Ureter bladder anastomat

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

technical field [0001] The invention relates to a ureteral bladder stapler. Background technique [0002] Ureter-bladder reimplantation anastomosis is a frequently used operation technique in clinical work of urology, including urological tumors, ureteral strictures, and kidney transplantation. [0003] However, the anatomical position of the bladder is deep, the surgical exposure is poor, the manual anastomosis of the ureter-bladder is complicated and time-consuming, and the incidence of complications such as postoperative leakage and stenosis is high. Posterior tissue edema and anastomotic leakage lead to ureteral stenosis, but it also brings complications of catheterization, increases the chance of urinary system infection, and affects the peristaltic function of the ureter. It is easy to form stones and difficult to remove. At the same time, the double J tube is broken, and the double J tube may be retracted and displaced after the operation, making it difficult to remo...

AI Technical Summary

Problems solved by technology

[0003] However, the anatomical position of the bladder is deep, the surgical exposure is poor, the manual anastomosis of the ureter-bladder is complicated and time-consuming, and the incidence of complications such as postoperative leakage and stenosis is high. Posterior tissue edema and anastomotic leakage lead to ureteral stenosis, but it also brings complications of catheterization, increases the chance of urinary system infection, and affects the peristaltic function of the ureter. Easy to form stones, difficult to remove, double J tube breakage, and postoperative double J tube retraction and displacement may occur, resulting in difficult removal, and even the risk of requiring a second surgery to remove

Furthermore, the placed ureteral stent needs to be removed under cystoscope after operation, which virtually increases the chance and risk of invasive operation, and also brings unnecessary physical and mental pain and economic burden to the patient
