Abstract

An L-shaped cut-suture instrument includes a nail bin 1, a nail anvil 2, a rotary segment 3, a handle 4, a close handle 5, and a trigger handle 6. The close handle 5 is connected with the nail bin 1. Two rows of interlaced nails 7, 7' are arranged at the two sides of the nail bin 1. A strip-shaped blade 8 is disposed in the middle slot of nail bin 1. Minitype cylinders 9, 9' are arranged respectively on the two ends of nail bin 1. Plugs are disposed respectively in minitype cylinders 9, 9'. The outer terminals of plug handles 10, 10' connecting fixedly with plugs are fixed with the two ends of the strip-shaped blade 8. The sockets ends of minitype cylinders 9, 9' communicate with a same air charging ball 12 through relevant air charging guide tubes 11, 11'. The L-shaped cut-suture instrument can do cutting and suturing at the same time, it is safe, convenient for operation and has a small size, and is especially suitable for excision of low position rectal cancer located at narrow deep position of pelvic cavity.

Description

" L " shape stapler

Technical field

This utility model relates to a kind of improvement of linear stiching instrument, and specifically a kind of " L " shape stapler is applicable to the narrow deep of pelvic cavity Low Rectal resection operation.

Background technology

In the Low Rectal resection operation of the narrow deep of pelvic cavity, need to adopt the linear suture device, to close the rectum stump, because the closure of rectum needs certain width, be generally 4-5cm, so need to adopt the apparatus of certain width, can realize operation, but because operation is operated in pelvic cavity, and the suitable apparatus of width can't enter darker pelvic cavity, this makes low Low Level rectal cancer patient be difficult to undergo surgery, at present, abroad for this type of patient, the general head rotatable type linear stiching instrument that adopts, it is the apparatus that the seam nail of two rows of mutually staggered is hammered into tissue with linear, its structure is by nail anvil, nail bin, rotate joint, handle, close handle, the percussion handle constitutes, and closes handle and is connected with nail bin, closes handle and makes nail bin and nail anvil closure by holding, and then press the percussion handle, suturing nail in the nail bin is pressed in the nail anvil, thereby sews up, this stiching instrument is according to intestinal tube thickness difference, divide 30mm, 55mm, three kinds of specifications of 60mm, but the obvious deficiency that this stiching instrument exists is locking to sew up, and can not cut simultaneously, can only cut off by the reuse shears after stitching, because pelvic cavity is narrow, so operation is very bothersome.The linear Endo-GIA of domestic use, be respectively to hammer into the seam nail that two rows of mutually staggered is arranged on the both sides of tissue, and can with scalpel the tissue between the suture be carried out from disconnected apparatus simultaneously, its model has 55mm, 75mm, 80mm, be used to do the storage bag of colon or small intestinal more, the advantage of this apparatus is safe and reliable, stitching convenience, neat, and its weak point is that volume is bigger, does not fit into operation of low rectal carcinoma.

Summary of the invention

The purpose of this utility model is to provide a kind of and can locking sews up, and can excise simultaneously again, and volume is little, can carry out " L " shape stapler of Low Rectal resection operation in the narrow deep of pelvic cavity.

For reaching above purpose, the technical scheme that this utility model adopted is: be somebody's turn to do " L " shape stapler, by nail bin, nail anvil, rotate joint, handle, close handle, the percussion handle constitutes, closing handle is connected with nail bin, the seam nail that the both sides of nail bin respectively have two rows of mutually staggered to arrange, it is characterized in that in the centre joint clip slot of nail bin, being provided with the strip blade, minitype cylinder is established at two ends at nail bin respectively, in minitype cylinder, be respectively equipped with piston, two ends of the outer end of the piston handle of fixedlying connected with piston and strip blade are fixed, the seat end of minitype cylinder is connected with same inflatable ball by corresponding inflating catheter respectively, by continuous compressive charge ball, make two piston handles overhanging synchronously, then can realize in the blade low water of strip insert tangential nail anvil.This utility model is also implemented by following measure: the width of described strip blade is 2-3mm, the height sum of the width of strip blade and minitype cylinder and the thickness of nail bin are consistent, the diameter of minitype cylinder is to be advisable in the nail bin housing of packing into, when the contraction of gas in the minitype cylinder, the strip blade is entered in the nail bin fully.

The beneficial effects of the utility model are: can sew up, can excise simultaneously again, and disposable finishing, safe and reliable, easy to operate, volume is little, is specially adapted to the excision of the narrow depths of pelvic cavity Low Rectal.

The specific embodiment

Make this utility model with reference to accompanying drawing 1,2,3,4.Be somebody's turn to do " L " shape stapler, by nail bin 1, nail anvil 2, rotate joint 3, handle 4, close handle 5, percussion handle 6 constitutes, closing handle 5 is connected with nail bin 1, the seam nail 7 that the both sides of nail bin 1 respectively have two rows of mutually staggered to arrange, 7 ', in the centre joint clip slot of nail bin 1, be provided with strip blade 8, minitype cylinder 9 is established at two ends at nail bin 1 respectively, 9 ', at minitype cylinder 9,9 ' in be respectively equipped with piston, the piston handle 10 of fixedlying connected with piston, 10 ' the outer end and two ends of strip blade 8 fix, minitype cylinder 9,9 ' seat end respectively by corresponding inflating catheter 11,11 ' be connected with same inflatable ball 12, by compressive charge ball 12, can make in the blade low water 13 of strip blade 8 tangential nail anvils 2.The width of described strip blade 8 is 2-3mm, the width of strip blade 8 and minitype cylinder 9,9 ' the height sum and the thickness of nail bin 1 consistent, minitype cylinder 9,9 ' the housing of diameter with the nail bin 1 of packing in be advisable, when the contraction of gas of minitype cylinder 9,9 ' interior, strip blade 8 is entered in the nail bin 1 fully.
