Description

Implement for anastomosing gallbladder with intestines

This utility model relates to a kind of medical operation apparatus, particularly makees the anastomat of gallbladder gut surgery.

At present,, adopt a kind of new art formula, promptly do hole shape resection and anastomosis art at 12 intestinal rear walls and common bile duct forearm to suffering from the patient that lower common bile duct is narrow, block.With rebuild gallbladder intestinal passage solve narrow because of lower common bile duct, block the cholestasis problem that causes.This new art formula is still tact anastomosis at present, and this identical method not only complicated operation, operating time is long, and is easy to pollute the art open country, and " funnel " syndrome takes place postoperative easily.

In order to solve long problem of suture manual technique complicated operation and time, once there be a kind of " circular stapler " can make the hole resection and anastomosis.But because of its structure is that operation with gastrointestinal and intestinal intestinal is an object, sews up to guide into and cut the hole with apparatus and coincide though this kind anastomat is cut the hole to maneuver, the hole of cutting that its frame mode is not suitable for the gallbladder intestinal coincide.Its main cause is: the locating rod of circular stapler is to be vertically fixed on the collet of disc type, like this, will be earlier before the operation cuts a mouth cutting the position, hole, then, again following locating rod in intestinal is passed from this mouth, make the disk collet be attached to intestinal wall fully, must turn round while passing.This is quite difficult in narrow biliary tract, and bigger collet is difficult again near distal common bile duct, therefore, forms " hopper zone " cut below the position, hole easily.If with less collet, though can solve the problem of close distal common bile duct, can produce and cut the big inadequately problem in hole, and this operation cut hole size and just particularly important.

The purpose of this utility model is that a kind of improved gallbladder intestine anastomat will be provided.It can rebuild lower and enough big passage with the hole shape and the location structure of uniqueness between common bile duct antetheca and resected duodenal posterior wall, effectively prevent the generation of postoperative " funnel syndrome ".Simultaneously,, cut the hole and sew up these three complicated operations, finish with apparatus once the location in the gallbladder gut surgery.

The purpose of this utility model is achieved in that the gallbladder intestine anastomat is made up of Hole cutting device and collet.The Hole cutting device cross section is that the ellipse or the angle of cut are rounded triangle.The locating rod separated into two parts: a part is a locating rod, and the one end is tapered and be threaded, and the other end has spanner.Locating rod is that the rear end from Hole cutting device is inserted into front end, and tapering point exposes at cutting knife and shuttle tube front.Another part is a collet, and collet is the semiellipsoid of a band handle, and the holder handle is a round bar, and the planar side of semiellipsoid studs with plastic plate and leaves conical bolt hole.Utilize the elasticity of biliary tract soft tissue during operation, following collet in biliary tract is directly shifted onto distal common bile duct, locate facing to cutting the hole with planar side, the tapering point that reuse exposes is aimed at the conical bolt hole on the collet, penetrate impact wrench behind the soft tissue, just can excise, coincide into an ellipse or the angle of cut is rounded triangle gallbladder intestinal passage.

Therefore this utility model, has not only been simplified operation sequence, and has been shortened operating time significantly because be to carry out the gallbladder intestinal with the operating theater instruments of special use to cut the hole anastomosis.Simultaneously, this knife-edge and collet are to press natural shaped design between the gallbladder intestinal, can not only directly push choledoch-lower position to collet, and reduced and located preceding otch, the complicated processes of turning round, thereby enough cut greatly under the prerequisite in hole in assurance, reduced the generation of " funnel syndrome " to greatest extent.In addition, collet has the function of biliary tract sound and gall stone scoop in the operation again concurrently, and this anastomat coincide as the hole of cutting that is applied between gastrointestinal and intestinal intestinal, and is also comparatively suitable.
