The mechanism design of internal hemorrhoid clamping, cutting, stitching:
Nail bin lower plate 39, nail bin lower plate 39 is shelly, nail bin lower plate 39 two sides of tail all have some through holes 40, the relative through hole 40 in both sides is corresponding one by one, cutting blade 3 heads shuttle back and forth in nail bin lower plate 39, are equipped with some resilient keys 38 in rail groove 36, and the two ends of some resilient keys 38 are supported on respectively in through hole 40, the bottom surface of nail bin lower plate 39 has a gathering sill 41, and the guide part 35 of cutting blade 3 is plugged in gathering sill 41 and is slidably connected;
Some pushing slice of nail 45, ejector pin bar head, over against pushing slice of nail 45 bottoms, has the binding groove 46 of binding on pushing slice of nail 45, and binding groove 46 correspondences the nail mouth of every nail mouth group 44;
Nail supporting base 47 and minor flaps 48, minor flaps 48 is interlocked with nail bin lower plate 39 afterbodys, nail supporting base 47 tops fasten nail supporting base lid 49, nail supporting base 47 two sides of tail are articulated in nail bin lower plate 39 afterbodys, nail supporting base 47 heads have lower indent 50 to the surface of afterbody, cutting blade 3 bizets 33 are arranged in lower indent 50, 47 times indent 50 both sides of nail supporting base have the suture trough 59 arranged corresponding to nail mouthful group 44, the bizet 33 of cutting blade 3 laterally runs through and is provided with a straight pin 51, straight pin 51 is positioned at nail supporting base 47 tops, be positioned at nail supporting base 47 afterbody upper surfaces and also be provided with V-reed 52, V-reed 52 middle parts have V-type groove 53 along its profile, the tip of V-reed 52 is towards nail supporting base 47 heads, V-reed 52 wherein is fixed in nail supporting base 47 upper surfaces on one side, another side is against on the inwall of minor flaps 48.
In the present embodiment, as Figure 23, nail bin 42 foremost to the small of the stock 2 length L 1 foremost be 136-267mm.
As Figure 17, effective stitch length L2 of nail bin 42 is 30-80mm, and the row of the nail mouth group 44 on every limit is 1-4 row, and it is identical or different that the nail mouth on every limit is organized 44 rows.Preferred every limit three nail mouth groups 44 in the present embodiment, both sides are symmetrical.
In actual operation, front is talked about, internal hemorrhoid is distributed as three orientation mostly, mostly be single hemorrhoid, after this anastomat is stretched into to anus, position situation difference for each patient due to hemorrhoid, therefore, if the front end of anastomat can't rotate, so just can only integrated overturn, at this time must cause the problem of the difficult operation of doctor, therefore the present embodiment has been done improvement to this, also comprise by two and break the rotary sleeve group 55 that rotary sleeve 54 is spliced into, the small of the stock 2 front ends have a circle swivelling chute 56, rotary sleeve group 55 front ends encase gun barrel 1 outer wall, rear end and swivelling chute 56 are rotationally connected, often break rotary sleeve 54 inwalls and there is protruding cylinder 57, gun barrel 1 locates to have near the small of the stock 2 the second pin-and-hole 58 run through foremost, the cylinder 57 of rotary sleeve 54 is plugged in the second pin-and-hole 58.After above-mentioned design, the small of the stock 2 main parts do not need to rotate, can hover over the position of the most applicable doctor's operation, at this moment as long as rotate rotary sleeve group 55, because the second pin-and-hole 58 of gun barrel 1 is grafting with the cylinder 57 on rotary sleeve, be also that both are synchronous rotations, and connect the spherical structure in axostylus axostyle 30 two ends exactly in order to produce relative rotation rather than to fix dead, and cutting blade 3, nail bin 42, nail bin lower plate 39, nail supporting base 47, nail supporting base covers 49 grades and gun barrel 1 for directly or indirectly connecting firmly, can know that thus anastomosed by instrument section is also along with the rotary synchronous of rotary sleeve group 55 rotates, just can rotate so like this proper site clamps hemorrhoid and carries out the cutting and stitching action, and the small of the stock 2 main parts do not need to rotate, facilitated medical worker's operation.
Specific works principle of the present utility model is as follows: press main handle 5, cingulum on main handle 5 moving first, the second duplicate gear rotates, the second duplicate gear is by rack-and-pinion driving rack slide block 21, at this moment rack slide 21 moves forward, promote to connect axostylus axostyle 30 reaches, and then drive cutting blade 3 moves, at this moment cutting blade 3 bizets 33 enter in the lower indent 50 of nail supporting base 47 along with cutting blade 3 reaches, and be positioned on bizet 33 straight pin 51 roles be exactly along with bizet 33 after lower indent 50 reaches, because straight pin 51 is positioned at nail supporting base 47 tops always, straight pin 51 can contact with nail supporting base 47 upper surfaces and by nail supporting base 47 belows, at this moment V-reed 52 can compressive deformations and in compressive state, closure along with nail supporting base 47, the staple that the nail mouth of below nail bin 42 is organized 44 interior layouts upwards ejects under the effect of pushing slice of nail 45, here pushing slice of nail 45 promotes by the ejector pin bar, ejector pin bar and pushing slice of nail 45 contact positions are wedge structure, ejector pin bar horizontal direction move through wedge structure after pushing slice of nail 45 just at vertical direction, eject, the ejector pin bar is fixed on blade coupling block 31, after staple is ejected, suture trough 59 stress deformations that run into nail supporting base 47 bottom surfaces can complete sews up action, 43 move to take advantage of a situation and just hemorrhoid are cut in cutting groove and the thing followed is exactly cutting blade 3, the hemorrhoid that cut tightly are clipped between nail bin 42 and nail supporting base 47, whole operation hemorrhoid cutting is extractd partly and has just been finished thus.
In this utility model, there is the nail of layout mouthful group 44 cutting groove 43 both sides, the purpose of doing like this is double-purpose, because single-point cutting hemorrhoid only need to be used wherein side three nail mouth groups 44, and opposite side does not need to use, such as hemorrhoid are positioned at the right of anus wall, only have so three of the right to queue effect, if hemorrhoid are positioned at the left side of anus wall, only have so three of the left side to queue effect.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, the relevant staff can, in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to the claim scope.
