fig1 - 6c shows various components of an exemplary embodiment of a device according to the present disclosure . as show in these drawings , the exemplary device has three primary parts , e . g ., a first part i , a second part ii and a third part iii . the first part i ( as shown in , e . g ., fig1 - 3d ) comprises a hollow portion 1 which includes a tapered end or insertion tip 16 which is structured or configured for an insertion into or propagation through a bodily lumen or another anatomical structure , a first handle grip 5 ( which is proximal with respect to the tip 16 ) and a connecting section 4 . the second part ii ( as shown in , e . g ., fig1 , 2 and 4 a - 4 d ) comprises a second handle grip 8 (( which is distal with respect to the tip 16 ) and a first closure member 9 , which can be non - releasably connected . the third part iii ( as shown in , e . g ., fig1 , 2 and 5 a - 5 d ) comprises a second closure member 10 . the exemplary device provides a handle 2 which comprises the first handle grip 5 of the first part i and the second handle grip 8 of the second part ii . referring to fig1 , 2 , 6 a and 6 b , the exemplary device has a first spring 12 and a second spring 13 , whereas the first spring 12 can be provided closer to the tip 16 than the second spring 13 , and both of which can have two or more fixation points . the first spring 12 can includes ( i ) a first fixation point 12 a provided at or on the first handle grip 5 of the first part i ( as also shown in fig3 a and 3c ) and ( ii ) a second fixation point 14 ( as also shown in fig4 a , 4 c and 4 d ) located on and below a surface of the first closure member 9 . the second spring 13 also has ( i ) a first fixation point 13 a located on or at the second closure member 10 ( as also shown in fig5 b and 5c ), and ( ii ) a second fixation point 15 located on and below the surface of the first closure member 9 ( as also shown in fig4 d ). when the exemplary device is assembled , the second spring 13 is provided or positioned just below a particular surface 20 of the second closure member 10 , while also being coupled to the first fixation point 13 a thereof . any of the fixation points 12 a , 13 a , 14 and / or 15 can be metal and / or plastic knob ( s ) or other members to which the respective first and second springs 12 , 13 can be attached , clipped unto and / or adhered to , e . g ., possibly with glue , clips , etc . the exemplary details of the first and second springs 12 , 13 are illustrated in fig6 a and 6b . however , it should be understood that other shapes and / or or sizes of the springs are conceivable and are within the scope of the exemplary embodiments of the present disclosure . fig1 and 2 show that the first spring 12 couples the first part i and the second part ii to one another . these drawings also illustrate that the second spring 13 couples the first and second closure members 9 , 10 to one another , which are slidably engaged with each other . as shown in fig1 and 2 , the exemplary device includes a window 6 which is enclosed between and formed by at least two opposing clamping surfaces , e . g ., a first opposing clamping surface 7 a ( which is part of the hollow portion 1 of the first part i ), and a second opposing clamping surface 7 b ( which is part of the second closure member 10 of the third part iii and provided on the edge thereof ). the second clamping surface 7 b is moved toward the first clamping surface 7 a by movable the third part iii toward the first clamping surface 7 a to close or reduce the size of the window 6 and away from such first clamping surface 7 a to open or increase the size of the window 6 . such movement of the third part iii can be actuated by squeezing and / or releasing the handle 2 of the exemplary device . for example , according to one exemplary embodiment of the present disclosure , when the second handle grip 8 is moved toward the first handle grip 5 by squeezing , during such exemplary squeezing motion by the operator &# 39 ; s hand , the window 6 size is reduce , by , e . g ., being closed until it meets an obstacle , such as , for example , a protruding tissue 17 ( as shown in fig1 ). in addition , the window 6 is intended to be closed when the first and second opposing clamping surfaces 7 a , 7 b meet each other ( as shown in fig2 ). thus , the window 6 becomes bigger when the second closure member 10 moves away from the first opposing clamping surface 7 a , and smaller when the second closure member 10 moves towards the first opposing clamping surface 7 a . in an exemplary operation , when the second handle grip 8 is moved toward the first handle grip 5 , for example , during a squeezing motion by the hand of the operator , the second part ii pulls on the second spring 13 . this is because the second spring 13 is connected at one end thereof to the second part ii via the second fixation point 15 ( as shown in fig4 a , 4 c and 4 d ) which is located on and below a surface of the first closure member 9 of the second part ii . the strength of the second spring 13 is selected or configured so as to facilitate the second main part ii to pull the second closure member 10 in the same direction as the direction of propagation of the first closure member 9 . indeed , during the exemplary operation , the second closure member 10 moves the first closure member 9 forward toward the first clamping surface 7 a by pulling ( e . g ., likely without significant stretching ) the second spring 13 , provided that the second closure member 10 does not meet the obstacle in the window 6 . indeed , such pulling motion is effectuated since another end of the second spring 13 is connected to the first fixation point 13 a located on or at the second closure member 10 and below the particular surface 20 thereof ( as also shown in fig5 b and 5c ). thus , the second spring 13 acts as a spring coupling arrangement between the second part ii and the third part iii . as shown in fig1 , if the second closure member 10 meets the obstacle in the window 6 ( e . g ., the protruding tissue ), the forward motion of the second closure member 10 in the same direction as that of the second part ii stops completely or for the most part . at the same time , the second part ii of the exemplary device continues to move forward in the same direction , and also ( simultaneously ) cause the second spring 13 to stretch . as a result , the first closure member 9 slides over the second closure member 10 towards the first clamping surface 7 a or the end or tip 16 , without further affecting the forward movement of the second closure member 10 and absent any further significant compression of the tissue situated within the window 6 . this exemplary effect is caused by the fact that when the second opposing clamping surface 7 b of the second closure member 10 contacts and attempts to press on the tissue provided within the window 6 , this negative pressure cases the second spring 13 to stretch . in this manner , while the second closure member 10 of the third part iii is prevented from moving forward by the tissue , a tension is continued on the second spring 13 , although allowing the first closure member 9 of the second part ii to continue its forward motion toward the tip 16 . such tension on the second spring 13 facilitates an approximately constant compression on the tissue . indeed , as a result , a constant tissue compression ( e . g ., on the tissue or on any other object ) can be accomplished in the window 6 . such constant tension or compression can be largely separate from or independent of the force exerted by the operator on the handle 2 , for example , the compression of the tissue can be mainly dependent upon various properties of the second spring 13 , the connections thereof to the first and second parts ii , iii , and the properties of the compressed tissue 17 in the window 6 . in addition , according to another exemplary embodiment of the present disclosure , the first spring 12 can be useful in facilitating the operation of the exemplary device . for example , when the second handle grip 8 is moved toward the first handle grip 5 , e . g ., during the squeezing motion by the hand of the operator , the second part ii is simultaneously pulls on and stretches the first spring 12 ( as shown in fig2 ). this is because one end of the first spring 12 is coupled to the second fixation point 14 ( as shown in fig4 a , 4 c and 4 d ) located on and below the surface of the first closure member 9 of the second part ii , and the other end of the first spring 12 is coupled to the first fixation point 12 a provided at or on the first handle grip 5 of the first part i ( as shown in fig3 a and 3c ). in this manner , the first spring 12 is stretched by the forward movement of the first closure member 9 toward the first clamping surface 7 a or the end or tip 16 , while the first part i is stationary with respect to the tip 16 . during the exemplary operation , and referring to fig1 , when the squeezed handle 2 is released , the first spring 12 has the tension to cause itself to return to its original ( e . g ., non - stretched or less - stretch ) configuration , thereby pulling on the first closure member 9 of the second part ii until the second part ii returns to its non - deployed ( e . g ., open or original ) position . again , this is caused by the first spring 12 being attached to a stationary first part i via the first fixation point 12 a , and pulling the first closure member 9 of the second part ii back to its original position due to the first spring 12 being connected to the second fixation point 14 of the first closure member 9 . in addition , as the second part ii is in the process of returning to its non - deployed position ( shown in fig2 ) with the assistance of the first spring 12 , the second part ii also pulls on and effectuates further tension of the second spring 13 , which pulls back the second closure member 10 due to its coupling to the first fixation point 13 a thereof until the second closure member 10 returns to its non - deployed position . when the second closure member 10 moves back to such position , the window 6 becomes enlarged , e . g ., until it is fully open ( as shown in fig2 ). it will further be appreciated
