fig1 illustrates examples of endo - cutter or micro - cutter and stapling systems 100 that can be alternatives or replacements to suturing . in particular , these endo - cutter or micro - cutter and stapling systems 100 are especially useful as alternatives or replacements to suturing in minimally - invasive surgical procedures . as illustrated in the figure , the operation of cutting and stapling is performed through a long slim shaft 104 . the actual operations of clamping , cutting , and stapling of tissue are performed at the distal - end 106 of the shaft 104 , and the control operations of these procedures are performed at the handle assembly 102 . the distal - end 106 may include a stapling system comprising of a staple channel and a staple anvil , which are illustrated in fig1 . the staple channel may include a staple holder or a staple cartridge for holding staples . the staple anvil deforms the staples as they are deployed . as the staples are deployed , the staples pierce the target tissue and the staple anvil deforms the staples to secure the staples against the target tissue . further illustrated , the shaft at the distal - end may be substantially flexible and may be articulated . for example , near the distal - end of the shaft may include an articulated section 108 . various versions of the endo - cutter or micro - cutter stapling systems may have non - articulated rigid shafts , while other versions may include substantially flexible or flexible portions that can be articulated . these and other features allow such examples of endo - cutter or micro - cutter and stapling systems ( e . g ., microcutter xpress ™ and microcutter xchange ™, which are designed and manufactured by cardica inc . of u . s . a .) to be ideally suited as alternatives or replacements to suturing . greater detailed discussions of endo - cutter or micro - cutter stapling systems are described in u . s . patent application ser . no . 12 / 323 , 309 , filed on nov . 25 , 2008 ; u . s . patent application ser . no . 12 / 400 , 760 , filed on mar . 9 , 2009 ; u . s . patent application ser . no . 12 / 400 , 790 , filed on mar . 9 , 2009 ; u . s . patent application ser . no . 12 / 477 , 065 , filed on jun . 2 , 2009 ; u . s . patent application ser . no . 12 / 787 , 708 , filed on may 26 , 2010 ; u . s . patent application ser . no . 13 / 093 , 791 , filed on apr . 25 , 2011 ; u . s . patent application ser . no . 12 / 477 , 302 , filed on jun . 3 , 2009 ; u . s . patent application ser . no . 12 / 489 , 397 , filed on jun . 22 , 2009 ; u . s . patent application ser . no . 12 / 612 , 614 , filed on nov . 4 , 2009 ; u . s . patent application ser . no . 12 / 840 , 156 , filed on jun . 20 , 2010 ; u . s . patent application ser . no . 13 / 028 , 148 , filed on feb . 15 , 2011 ; u . s . patent application ser . no . 13 / 048 , 674 , filed on mar . 15 , 2011 ; u . s . patent application ser . no . 13 / 094 , 716 , filed on apr . 26 , 2011 ; u . s . patent application ser . no . 13 / 094 , 805 , filed on apr . 26 , 2011 ; u . s . patent application ser . no . 13 / 093 , 743 , filed on apr . 25 , 2011 ; u . s . patent application ser . no . 13 / 105 , 799 , filed on may 11 , 2011 ; and u . s . patent application ser . no . 13 / 294 , 160 , filed on nov . 10 , 2011 , all of which are incorporated herein by reference . fig2 a through fig2 c illustrate exposed and exploded views of the body , handle , and trigger elements of one example of endo - cutter or micro - cutter and stapling system 100 handle assembly 102 where the clamp and deployment mechanisms ( e . g ., 310 and 1010 in fig2 a ) are illustrated . in addition , some of the piece - part components of the handle assembly 102 are separately marked with reference numerals for ease of illustration and discussion , as pertain to and illustrated in fig2 b and fig2 c . for ease of discussion and additional reference , component or parts identification to the referenced numerals associated with fig2 b are : ( 1 )— release ; ( 2 )— pin ( release ); ( 3 )— spring ( mode button ); ( 4 )— pin ( release spring ); ( 5 )— handle ( right ); ( 6 )— handle ( left ); ( 7 )— pin ( clamp lock ); ( 8 )— pin ( clamp slide ); ( 9 )— spring ( trigger ); ( 10 )— spring ( release ); ( 11 )— clamp lock ; ( 12 )— clamp lock tab ; ( 13 )— deployment pulley ; ( 14 )— pin ( deployment pulley ); ( 15 )— pin ( gear ); ( 16 )— slide ( clamp ); ( 17 )— slide ( deployment ); ( 18 )— washer ( gear ); ( 19 )— clamp pulley & amp ; gear ; ( 20 )— deploy pulley & amp ; gear ; ( 21 )— cable deploy ; ( 22 )— cable clamp ; ( 23 )— trigger subassembly ; ( 24 )— adhesive ; and ( 25 )— grease . for ease of discussion and additional reference , component or parts identification to the referenced numerals associated with fig2 c are : ( 1 )— mode button ; ( 2 )— spring ( ratchet ); ( 3 )— ratchet ; ( 4 )— spring ( trigger clamp gear ); ( 5 )— trigger gear ( deploy ); ( 6 )— trigger gear ( clamp ); ( 7 )— spring ( trigger deploy gear ); ( 8 )— trigger ( left ); ( 9 )— trigger ( right ); and ( 10 )— adhesive . as can be depicted from the fig2 a , fig2 b , and fig2 c , the system includes a trigger 302 in the handle assembly 102 to activate the gear system 300 ( as indicated in fig3 a ) that in turn operate either the clamp or deploy mechanisms ( e . g ., 310 , 1010 ), depending on which operational mode is selected by a mode switch mechanism 910 , 912 ( as illustrated in fig9 a , fig9 b , and fig1 ). fig3 , fig4 , and fig5 illustrate the clamp mechanism components 310 without the body and handle cover of the endo - cutter or micro - cutter and stapling system 100 for ease of illustration and discussion . as can be appreciated from the figures , the trigger member 302 activates a set of clamp gears 300 which in turn pulls on a clamp cable member 322 that asserts a pull force onto a clamp slide member 332 and clamp spool member 342 combination . to be discussed in further detail , as the clamp slide member 332 and clamp spool member 342 combination is either pulled back by the clamp cable member as may be appreciated from the illustration of fig3 or pushed forward by a spring member 412 as illustrated in fig4 , the position of the slide member 332 and spool member 342 combination may be locked into various clamping mode positions ( e . g ., first mode , second mode , or third mode ) by the clamp lock member 512 as illustrated in fig5 . the slide member 332 and spool member 342 can be locked in various positions as a clamp slide - pin member 522 travels either backward ( as pulled by the cable member 322 ) or forward ( as pushed by the spring member 412 ) along the clamp lock member 512 . the clamp slide - pin 522 may rest on the clamp lock member 512 or in the various notches or detents ( e . g ., 513 , 523 , etc .) that are on the clamp lock member 512 . the combination of the slide member 332 , spool member 342 , and clamp slide - pin member 522 are configured to operate in concert to hold the jaws ( e . g ., the staple channel and staple anvil ) of the stapling member 106 in various operational modes or positions — such as , a first mode or trocar mode , a second mode or open mode , or a third mode or clamping mode ( the stapling member of the distal - end 106 is illustrated in fig1 ). as illustrated in fig5 , the clamp slide - pin member 522 is resting near the tip of the clamp lock member 512 ( e . g ., in a first mode or trocar mode ), not in any one of the notches or detents ( e . g ., 513 , 523 ). these various clamp modes ( e . g ., first mode or trocar mode , second mode or open mode , or third mode or clamping mode , etc .) are associated with various clamp operational modes of the clamp member 106 or stapling member 106 located at substantially the distal portion of the long slim shaft 104 of the endo - cutter or micro - cutter and stapling system 100 as illustrated in fig1 . typically , in a first state or neutral state , the clamp mechanism components 310 set the clamp or stapling member 106 in a first mode or trocar mode . in this mode , the jaws of the clamp member 106 of the cutter and staple system 100 may be in a smallest or most compact configuration , which allows it to be inserted through a small opening or access port for executing cutting and stapling procedures in minimally invasive surgical operations . as mentioned previously , for example , the clamp 106 may be comprised of stapling jaw components including a staple channel ( with a staple holder or staple cartridge ) and a staple anvil . as can be observed in fig6 , the slide member 332 is substantially at its most extended position and the clamp slide - pin member 522 is positioned or resting at substantially the tip of the clamp lock member 512 . also , the trigger member 302 is in its released - state or extended - state , ready to be use — such as ready to be squeezed or activated by a surgeon . the clamp mechanism components 310 are activated by a partial - squeeze of the trigger member 302 , as illustrated in fig7 . the partial - squeeze of the trigger member 302 activates the clamp gears 300 to rotate and asserts a pull force onto the slide member 332 to slide backwards toward the proximal portion of the cutter and stapling system 100 . as illustrated in fig7 , the slide member 332 has been pulled back and the clamp slide - pin member 522 is resting in a first notch or first detent 513 on the clamp lock member 512 . the backward movement of the slide member 332 asserts a pull force on the components of the jaws of the clamp ( e . g ., stapling members : staple channel and staple anvil — not shown ) which causes the jaws of the clamp to open in this second mode or open mode . in this second mode or open mode , staples or staple cartridges can be loaded into the clamp or stapling system ( e . g ., staple channel & amp ; staple cartridge combination ). also , after the cutting and stapling system is inserted into the target operational site , in the second mode or open mode , the clamp ( 106 ) can be positioned to grasp tissue for stapling . further illustrated in fig7 is that a clamp pin - release member or clamp lock release member 524 is in a second - level position in a substantially triangular slot 533 or the first slot 533 , on the clamp lock member 512 , as compared to a first - level position , when the clamp mechanism components 310 are in a first mode or trocar mode as illustrated in fig6 . the clamp pin - release member 524 in a second - level position may cause the clamp lock member 512 to be in a substantially angular orientation as compared to the clamp release - pin 524 in a first - level position . alternatively , the clamp pin - release member 524 in a second - level position may cause the clamp lock member 512 to be in a substantially greater angular orientation as compared to the pin - release member 524 in the first - level position . when the clamp release - pin 524 is in the first - level position , the clamp lock member 512 may be oriented in a substantially horizontal orientation . whereas , when the clamp release - pin 524 is in the second - level position , the clamp lock member 512 may be oriented in a slightly or substantially angular orientation or in a substantially non - horizontal orientation . fig8 illustrates the clamp mechanism 310 components in a third mode or clamping mode as caused by a full - squeeze or full - activation of the trigger member 302 . the full - squeeze of the trigger member 302 further advances the clamp gears 300 that winds up the cable member 322 , which further pulls the slide member 332 and spool member 342 combination backwards further towards the proximal portion of the cutter and stapling system 100 . the backward movement of the slide member 332 causes the clamp slid - pin member 522 to travel into a second notch or second detent 523 of the clamp lock member 512 . in this mode , the spool member 342 which connects or couples to the components of the jaws of the clamp 106 ( e . g ., stapling members ) causes the jaws of the stapling members 106 to clamp onto the tissue that is ready to be stapled . in this position , in the second notch or second detent 523 , the jaws are secured or locked in clamping mode . further illustrated in fig8 , the pin - release member 524 is in a third - level position . in this third - level position , the clamp lock member 512 is at a substantial angular orientation , in which the clamp lock member has pivoted about a clamp pin - lock member 702 in a third notch or third detent 543 . in this position , the clamp lock member 512 securely holds the clamp slide - pin 522 in the second notch or second detent 523 of the clamp lock member 512 . to release the jaws of the clamp or the stapling member 106 , the clamp lock member 512 can be moved to “ unlock ” or “ release ” the clamp slide - pin member 522 from the second notch or second detent 523 by adjusting or pushing forward the pin - release member or clamp lock release member 524 in the triangular slot 533 . the releasing adjustment or movement of the pin - release member 525 causes the clamp lock member 512 to move or position itself in a substantially “ opposite ” angular orientation , which allows the clamp slide - pin member to be released from the second notch 523 as the spring member 412 pushes the clamp spool member 342 and clamp slide member 332 forward . similarly , the clamp slide - pin member 522 can be released from the first notch 513 in a substantially similar manner . with the clamp mechanism 310 is in the third mode and target tissue is clamped , the next phase of the operation is ready to be deployed . fig9 a and fig9 b illustrate a backside view of an endo - cutter or micro - cutter and stapling system 100 where a mode switch mechanism 910 and a mode selection member 912 are illustrated . a stand - off member 902 is shown to engage the clamp gears 300 that drive the clamp mechanism 310 . fig1 illustrates the deploy mechanism components 1010 that are used to deploy or drive an endo - cutter or micro - cutter 100 to cut target tissue . cutting and stapling of target issue may occur at substantially the same time or the operations may be separated by a substantially small time incremental period . as illustrated in fig1 , the deploy mechanism 1010 comprises of a set of deploy gears 1030 , a deployment cable member 1022 , a combination of deployment slide member 1032 and a deployment spool member 1042 , and a deploy pulley member 1052 . fig1 illustrates a backside - view of an endo - cutter or micro - cutter and stapling system where a mode switch mechanism 910 has been activated to place the endo - cutter or micro - cutter and stapling system 100 in a deployment mode . for example , a mode switch button 912 has been pushed or activated to move the stand - off member 902 of the mode switch mechanism 910 to engage the gears 1030 of the deploy mechanism 1010 , while disengaging with the clamp drive gears 300 of clamp mechanism 310 . once the deploy mechanism 1010 is engaged , activation of the trigger member 302 activates the gears 1030 of the deploy mechanism 1010 which advances or drives the endo - cutter or micro - cutter 100 to cut target tissue . additionally , the deployment mechanism 1010 may also advances or drives the endo - cutter or micro - cutter 100 to staple target tissue . fig1 a and fig1 b illustrate the deployment mechanism components of the endo - cutter or micro - cutter and stapling system in a deployment mode ; for example , in a condition ready to deploy an endo - cutter or micro - cutter . as illustrated in fig1 b , a deploy ratchet member 1212 engages a first tooth 1242 of a first deploy gear 1214 . fig1 a and fig1 b illustrate the deployment mechanism components of the endo - cutter or micro - cutter and stapling system in a first deployed mode ; for example , a first trigger - squeeze in the deployment mode . as the trigger member 302 is squeezed or activated , the deploy ratchet member 1212 urges or advances the first deploy gear 1214 , as illustrated in fig1 b . the first deploy gear 1214 acts on a second deploy gear 1216 which winds and pulls on a deploy cable member 1222 . the deploy cable member 1222 pulls on the combination of deploy slide member 1032 and deploy spool member 1042 to advance the combination to a first deployed position , illustrated in fig1 a . the movement of the combination advances the components associated with the endo - cutter or micro - cutter ( such as a deployment strip member 1252 , a knife member ( not shown ), etc .) to a first position ; cutting targeted tissue to a certain distance or interval . additional deployment members may also be activated , such as a wedge member ( not shown ) to drive and deploy staples in the clamp member 106 to correspondingly staple the targeted tissue to a certain distance or interval . fig1 a and fig1 b illustrate the deployment mechanism components of the endo - cutter or micro - cutter and stapling system in a second deployed mode ; for example , a trigger - release state after the first deployed mode . in fig1 a , it is illustrated that the trigger member 302 is released , which causes the deploy ratchet member to return or retreat and engages the second tooth 1244 of the first deploy gear 1214 . in this position , the deploy mechanism 1010 is ready for further deployment . fig1 a and fig1 b illustrate the deployment mechanism components of the endo - cutter or micro - cutter and stapling system in a third deployed mode ; for example , a second trigger - squeeze after the second deployed mode . as illustrated in fig1 a , the trigger member 302 is squeezed to advance the first deploy gear 1214 , which is illustrated in fig1 b . the advancement or rotation of the first deploy gear advances or rotates the second deploy gear 1216 in an opposite direction , which winds or pulls on the deploy cable member 1222 . the deploy cable member 1222 winds around a deploy pulley 1052 and pulls the combination of deploy slide member 1032 and deploy spool member 1042 . the deployment member combination ( 1032 and 1042 ) is moved forward or advanced to a second deployed position , as illustrated in fig1 a . the movement of the deployment member combination ( 1032 and 1042 ) advances or drives the components associated with the endo - cutter or micro - cutter further forward ( e . g ., a deployment strip member 1252 , a knife member ( not shown ), etc . ), thus further cutting the targeted tissue . additional deployment members may also be activated , such as a wedge member ( not shown ) to drive and deploy staples in the clamp member 106 to correspondingly staple the targeted tissue to a certain distance or interval . fig1 a and fig1 b illustrate the deployment mechanism components of the endo - cutter or micro - cutter and stapling system in a fourth deployed mode ; for example , a trigger - release state after the third deployed mode . as illustrated in fig1 a , the trigger member 302 is released , which allows the deploy ratchet member 1212 to return or retreat . the return of the deploy ratchet member 1212 allows it to engage a third tooth 1246 on the first deploy gear 1214 . the engagement of the deploy ratchet 1212 with the third tooth 1246 on the first deploy gear 1214 may provide sufficient adjustments to the engagement of the mode switch mechanism 910 to allow it to reset . for example , the adjustment may allow the mode switch mechanism 910 and / or the mode switch selection member 912 to reset or reengage the mechanisms and components of deploy and clamp operations to the first mode ( e . g ., clamp mechanism first mode ). the adjustment and engagement of the mode switch mechanism 910 and / or the mode switch selection member 912 may be triggered by the third tooth pushing on the deployment ratchet 1212 as the ratchet engages with the third tooth 1246 . the third tooth 1246 may be irregular - shaped or has a shape that is substantially different than the shape of the first tooth and / or second tooth of the first deploy gear 1214 . the mode switch mechanism 910 may be spring - loaded , such that the engagement of the deploy ratchet 1212 with the third tooth 1246 provides sufficient adjustment or movement to allow the spring - loaded mode switch mechanism 910 to reset . the resetting of the mode switch mechanism allows the stand - off 902 member to return to a position where the clamp gears 300 of the clamp mechanism 310 is engaged and in state of the first mode ( clamp mechanism first mode ), as illustrated in fig1 a and fig1 b . fig1 c and fig1 d illustrate side - views of the endo - cutter or micro - cutter and stapling system 100 illustrating that the mode switch mechanism 910 , 912 has been reset to place the endo - cutter or micro - cutter and stapling system 100 in the first mode or trocar mode . as may be appreciated from the illustrations , the clamp slide pin member 522 is positioned or resting near the tip of the clamp lock member 512 . also , the clamp pin - release member 524 is positioned or resting in the first - level position in the substantially triangular - shaped slot 533 in the clamp lock member 512 . the first - level position may allow the clamp lock member 512 to be in a substantially horizontal level , orientation , or position . fig1 a and fig1 b illustrate the deploy mechanism components in a deployed state illustrating that components or accessories ( e . g ., endo - cutter or micro - cutter ) attached or coupled to the deploying components have been deployed or advanced to their deployed state . for example , an endo - cutter or micro - cutter may be coupled to the deploy mechanism 1010 ( such as by way of the deployment slide member 1032 and deployment spool member 1042 ). as the deploy mechanism components are advanced in various modes , the endo - cutter or micro - cutter is correspondingly advanced forward to cut target tissue as part of the clamping , cutting , and stapling of the endo - cutter or micro - cutter and stapling system operations . multiple features , aspects , and embodiments of the invention have been disclosed and described herein . many combinations and permutations of the disclosed system may be useful in minimally invasive surgical procedures , and system may be configured to support various endo - cutters and / or stapling systems . one of ordinary skill in the art having the benefit of this disclosure would appreciate that the foregoing illustrated and describe features , aspects , and embodiments of the invention may be modified or altered , and it should be understood that the invention generally , as well as the specific features , aspects , and embodiments described herein , are not limited to the particular forms or methods disclosed , but also cover all modifications , equivalents and alternatives . further , the various features and aspects of the illustrated embodiments may be incorporated into other embodiments , even if not so described herein , as will be apparent to those ordinary skilled in the art having the benefit of this disclosure . although particular features , aspects , and embodiments of the present invention have been shown and described , it should be understood that the above discussion is not intended to limit the present invention to these features , aspects , and embodiments . it will be obvious to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the present invention . thus , the present invention is intended to cover alternatives , modifications , and equivalents that may fall within the spirit and scope of the following claims and their equivalents .
