A collapsible bladder-urethral stapler

Abstract

The invention provides a degradable urethrovesical anastomosis apparatus, used for tensioning and connecting a urinary bladder (10) and the residual end of a urethral canal (20) in a urethrovesical anastomosis operation, wherein the anastomosis apparatus (40) comprises a ring (41) which is connected to the urinary bladder (10); a plurality of sharp nails (411), which are in charge of hooking the urinary bladder (10) downwards, are arranged in a mode of surrounding the periphery of the ring (41); a plurality of hook pins (42), which are connected to the urethral canal (20) and extend downwards, are arranged in a mode of surrounding the ring (41); and a barb (421), which is used for hooking the urethral canal (20) and faces upwards, is arranged at the tail end of each hook pin (42). The anastomosis apparatus provided by the invention, by virtue of the anastomosis ring and the barbs, can respectively hook the urinary bladder and the urethral canal to tension the urinary bladder and the residual end of the urethral canal, so that the service time of a catheter is shortened and pain and inconvenience of a patient are relieved; and the anastomosis apparatus is conducive to urinary bladder and urethral canal organ function recovery of the patient.

Description

technical field [0001] The invention relates to a medical device, in particular to a stapler used for anastomosis of bladder and urethra during operations such as prostate or bladder diseases. Background technique [0002] Bladder cancer is one of the most common tumors in clinical urology in my country. It is a disease that directly threatens the survival of patients. Standard treatment; while radical prostatectomy is one of the most effective methods to cure localized prostate cancer, the key and difficult point of the operation lies in the reconstruction of the lower urinary tract, that is, the key technical issue of vesicourethral anastomosis. At present, manual suture is mostly used, but because the anastomosis is located at the bottom of the pelvis, the position is deep, and the operating space is narrow, the suture technique is difficult, the operation takes a long time, the anastomotic effect is difficult to guarantee, and a series of complications such as urinary fis...
