the present invention will be described as it applies to its preferred embodiment . it is not intended that the present invention be limited to the described embodiment . it is intended that the invention cover all modifications and alternatives which may be included within the spirit and scope of the invention . the present invention includes an improvement to the prior art field dressing tool 10 as shown in fig1 and 2 . the tool 10 is formed about axis 14 . tool 10 has a tip 12 at a first end thereof that is distal from a handle 20 . a series of substantially triangular barbs 16 are formed in angularly dispersed portions around tip 12 to extend radially outwardly from the rear portion of tip 12 . as in fig1 , the tool 10 is formed with four barbs 16 , although different numbers of barbs can be used . the tip 12 has a diameter , and the barbs 16 extend in opposite sides of the axes 14 to a width that is greater than the diameter . the diameter of the tip 12 should be sized for being inserted into the anus of a slain animal , such as a deer . the barbs 16 having a width at least twice as great as the diameter of the tip 12 has been found suitable . a shank 18 is substantially a coaxial extension of tip 12 along the axis 14 . the shank 18 terminates in the handle 20 that is formed transverse to the axis 14 . the shank 18 is formed substantially long to allow insertion of the tip 12 and barbs 16 into the anus of the animal by at least 3 - 4 inches while the handle 20 is being held by the user outside the body of the animal . as shown in the figures , the shank 18 and tip portion 12 are formed as an orthogonal cross of ribs 22 and connects at its proximal end to the handle 20 , formed in cross section ( not shown ) in the form of the letter “ h ”. the handle 20 can also be a linear extension of the shank 18 . as an alternative , the tip portion 12 can take on a generally hemispherical shape . to field dress an animal , the tip 12 is inserted into the anus of the animal as the handle 20 is pushed to move the barbs 16 into the body cavity . once the barbs 16 are beyond the anus , the handle is rotated sufficiently to cause the exposed points of the barbs 16 to ensnare the wall of the rectum . the handle 20 is then pulled back to remove the barbs 16 and the tip 12 of the tool 10 from the body cavity of the animal , thereby extracting a portion of the intestine . the exposed portion of the intestine is then tied or clamped to prevent accidental spilling of body waste materials . the improved tool for field dressing big game animals will now be described . the structure of the tool 30 is illustrated in fig3 - 5 . similar to the prior art tool 10 previously described , the tool 30 of the present invention is formed on an axis 34 and includes a tip portion 32 that is distal from a handle 40 . the tip portion 32 can also have a generally hemispherical shape . triangular barbs 36 are disposed around the tip 32 and extend radially outwardly from the rear portion of the tip 32 . a shank 38 extends from the tip portion 32 along the axes 34 . the shank 38 terminates in the handle 40 that is formed transverse to the axes 34 . the shank 38 and handle 40 are formed on an orthogonal cross of ribs 42 . as compared with the prior art tool 10 , the tool 30 of the present invention is longer in length and includes a barrier member 44 that extends away from the shank and is disposed between the opposite ends of the tool 30 . it is preferred that the barrier member 44 maintain a spaced - apart relationship with the handle 40 to allow the user &# 39 ; s hand to comfortably fit between the handle 40 and the barrier member 44 while gripping the handle 40 . it is also preferred that the barrier member be positioned sufficiently rearward of the tip 32 and barbs 36 so that the tool can be inserted into the anus of the slain animal by approximately 3 - 6 inches while the handle is being held by the user outside the body of the animal . the barrier member 44 as shown is generally perpendicular to the shank 38 and has a planer surface extending therefrom . those skilled in the art will appreciate that similar configurations at different angles and with some curvature could be used . the barrier member 44 acts as a stop to limit the length of the tool that can be inserted into the anus of the animal . in addition , the user can firmly grip the handle 40 while keeping the barrier member 44 snug against the animal , which gives the user greater control over the tool 30 . those skilled in the art will appreciate that the barrier member can take various shapes and forms . the preferred embodiment shows a barrier member 44 that is an annular flange having a diameter approximately 3 : 2 times greater than the diameter or width of the shank 38 . however , the barrier member could take on other shapes and need not be a continuous structure . important to the present invention is that the barrier member effectively limit the length of the tool 30 that is inserted into the anus of the animal . in its preferred form , the tool 30 as designed for field dressing deer has a length of approximately 8 inches with the barrier member 44 disposed 2 inches from the handle 40 . it is preferred that the tool 30 is manufactured by an injection molding process and that all of the parts of the tool are integrally formed , with the choice of plastics resin to be determined by the manufacturer . the method of using the field dressing tool 30 will now be illustrated with reference to fig6 - 9 , which are side elevation views of the rear portion of a large game animal , here a deer 50 . each of the figures show select internal organs depicted in dashed lines . the animal &# 39 ; s rectum 52 , which is the last section of the intestine , connects to the anus 54 at the animal &# 39 ; s rump 56 . the internal end of the rectum 52 continues as intestines that ultimately terminate at the stomach ( not shown ). the field dressing tool 30 is positioned in fig6 in alignment with anus 54 with the tip 32 adjacent to the anus 54 . the tool 30 is to be pushed in the direction indicated by arrow a until the tip 32 and barbs 36 have passed the anus 54 and entered the rectum 52 in the position as shown in fig7 . when the tool 30 is fully inserted into the rectum 52 , the barrier member 44 abuts the rump 56 of the deer 50 at the anus 54 . the barrier member effectively limits how far the tip portion 32 and barbs 36 can be inserted into the rectum 52 . this avoids causing unnecessary damage to the wall of the intestines . the barrier member 44 also maintains a spaced - apart relationship with the handle 40 , which allows the user to comfortably maintain a grip on and control over the tool 30 . it also avoids direct contact between the user &# 39 ; s hand and the anus 54 . as shown in fig7 , rectum 52 is stretched radially to accommodate and engage barbs 36 therein . the barrier member 44 limits the length of the tool 30 that can be inserted through the anus 54 and into the rectum 52 . the tool 30 is next rotated as indicated by arrow b through an angle of approximately 180 °. because the barbs 36 are formed along a series of perpendicular planes that pass through the axis 34 of the tool 30 , rotation of the tool 30 can be either in a clockwise or counterclockwise direction . with the extended sharp points of the barbs 36 stretched over the membrane comprising the rectum 52 , rotation of the tool 30 causes the barbs 36 to dig into and ensnare the wall of the rectum 52 . now referring to fig8 , the tool 30 is withdrawn in the direction indicated by arrow c from the animal &# 39 ; s anus 54 , drawing a section of the rectum 52 outside of the anus 54 . to provide ample space to tie or clamp the end of the rectum 52 , the tool 30 is pulled out of the anus 54 by approximately 10 - 12 inches . the tool 30 is then removed from the rectum 52 by cutting the intestinal wall either before or after the clamping or tying is done , as described below . as shown in fig9 , the extended section of the rectum 52 is tied into a knot 58 . as an alternative , a clamp ( not shown ) is applied and pulled tight enough to prevent solid waste from escaping through the rectum 52 during the remaining field dressing process . twisting the rectum 52 outside the body cavity of the animal prior to clamping serves to further prevent waste leakage . once the intestines are tied or clamped to prevent waste leakage , the field dressing process continues . the extended section of the rectum 52 is repositioned in the body cavity either by pushing the extended section through the anus 54 or pulling the extended section from within the body cavity after the cavity has been opened . the intestines and the balance of the digestive track are then removed through the abdominal opening along with the urinary track . the present invention contemplates numerous additions , alternatives , and options . that which has been disclosed is merely exemplary . the present invention is not to be limited to or by the specific embodiment disclosed herein . the invention is only to be limited by the claims appended hereto .
a field dressing tool for big game animals and a method for using same is disclosed . the tool includes a tip portion , a plurality of barbs extending radially and rearwardly from the tip portion , a shank extending from a rear portion of the barbs , and the handle on the shank opposite the tip portion . a barrier member is provided between the tip portion and the handle , and is positioned in a spaced - apart relationship with the handle . inserting the tip and barbs into the rectum causes radial stretching of the intestinal wall , and rotation of the tool causes ensnarement of the rectum on the barbs . the tool is retracted from the anus , pulling a section of rectum external to the animal to be closed to prevent leakage of bodily waste materials .
