Abstract

The invention relates to a ureter bladder anastomat which comprises a sleeve, a pull rod, a needle ejector, a base and a handle. The pull rod and the needle ejector are arranged in the sleeve, one end of the pull rod is connected with the base, the other end of the pull rod is connected with a drive device, a nail seat is arranged at the top end of the sleeve, a groove is reserved at the bottom end of the base, a pad is arranged in the groove and corresponds to the nail seat, the rear end of the nail seat is connected with the needle ejector, an anastomotic nail is arranged in the nail seat and positioned in the middle of the nail seat, a push rod is arranged at the rear end of the nail ejector, the handle is divided into a movable handle and a fixed handle, the movable handle is connected with the push rod, and the fixed handle is connected with the sleeve. The ureter bladder anastomat has the advantages that when the anastomat is used for anastomosis, under the circumstance of keeping an opening of the ureter smooth, a double-J catheter needs not to be placed, the ureter bladder anastomat is convenient to operate and feasible, needed time for surgical operation is shortened, and complications can be reduced probably.

Description

A kind of tubal bladder anastomat

Technical field

The present invention relates to a kind of tubal bladder anastomat.

Background technology

In the Urology Surgery clinical position, comprise urological cancer, stricture of ureter, renal transplantation operation etc., use the Uretero-bladder and replant the operating technology of anastomosis for often using.

Yet, the bladder anatomical position is dark, operation appears poor, the tact anastomosis complicated operation of Uretero-bladder is consuming time, though the incidence rate height of postoperative leakage of urine and complication such as narrow is by adopting double J pipe to insert prevention of postoperative tissue edema and anastomotic stoma leakage of urine preferably, stricture of ureter, but it has also brought the complication of putting pipe simultaneously, increased the urinary system infection chance, influenced ureteral wriggling function, the postoperative double J pipe is kept somewhere for a long time in addition, tube wall easily forms calculus, take out difficulty, have the double J pipe fracture simultaneously, and the double J pipe retraction might take place in postoperative, displacement, cause taking out difficulty, even the risk that needs second operation to take out.Moreover the ureter rack tube of laying needs postoperative to carry out getting under the cystoscope pipe operation, has increased chance and the risk of aggressive operation virtually, has also brought unnecessary body and mind misery and financial burden to the patient simultaneously.The problems referred to above are perplexing the clinician, and therefore, people are expecting a kind of easy day by day, and quick, safety, unsupported new method are finished the Uretero-bladder and replanted identical.

Summary of the invention

Technical problem to be solved by this invention provides a kind of anastomat that can be used in the tubal bladder replantation.

In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of tubal bladder anastomat, and its innovative point is: comprise sleeve pipe, pull bar, thimble device, base and hands handle;

Described sleeve pipe is a hollow circular tube, is provided with pull bar and thimble device in sleeve pipe, and an end of pull bar stretches out with base from the top of sleeve pipe and links to each other, and the other end of pull bar stretches out from the bottom of sleeve pipe and is connected with driving device, is provided with the nail seat on the top of sleeve pipe;

Described base is coniform, base is slapped together by the identical small footprint of several shapes, each small footprint is connected with pull bar by connecting rod, fixedly connected between described connecting rod and the small footprint, and flexibly connect between the pull bar, described connecting rod is driven by driving device, the bottom of each small footprint all is connected with base, described base is corresponding with the nail seat, the rear end of nail seat is connected with the thimble device, be provided with anastomosis staple and blade in the described nail seat, anastomosis staple is positioned at the medium position of nail seat, and the base relative with the anastomosis staple position is the concave surface of certain radian, and blade is positioned at the inboard of anastomosis staple, and blade is connected with the thimble device, is provided with push rod in the rear end of thimble device;

Described handle is divided into flexible handle and fixed handle, described flexible handle is connected with push rod, hinged forming between flexible handle and the push rod, and clearance fit between flexible handle and the sleeve pipe, described fixed handle and telescopic joint, fix between fixed handle and the sleeve pipe, be provided with back-moving spring between described flexible handle and the fixed handle.

Further, described anastomosis staple is the nonmetal nail that absorbs.

Further, described anastomosis staple is 6-8, distributes ringwise.

The invention has the advantages that: use the identical and traditional manual suture reconstruction Uretero-bladder path of this anastomat and compare, it has simple, quick, safe characteristics, coincide fast, and the anastomotic stoma sealing can prevent urine leakage; No foreign body in the anastomotic stoma tube chamber, internal mold is smooth, anti back-flow, the unimpeded rate height of postoperative needn't be placed double J pipe in the art, avoided the secondary cystoscope to have the wound operation to take out saddle, also avoided simultaneously double J pipe to keep somewhere the complication that causes, adopted anastomosis staple to adopt the nonmetal nail that absorbs to prevent calculus simultaneously, and need not to take out, improve success rate of operation, reduced doctor's labor intensity.
