Urethral anastomosis guide

Abstract

The invention belongs to the technical field of medical equipment, and provides a urethral anastomosis guide. The urethral anastomosis guide is used for facilitating urethral anastomosis for the difficulty of anastomosis of an existing urethral anastomosis guide. The urethral anastomosis guide comprises a main body, and a plurality of grooves are formed in the periphery of one end part of the mainbody and are distributed in the circumferential direction of the main body in an annular array mode. The six grooves are evenly distributed in the circumferential direction of one end of the main body. The part, provided with the grooves, of the main body is a bending part, and the groove forming positions are at angles of 30 degrees, 90 degrees, 150 degrees, 210 degrees, 270 degrees and 330 degrees with the bending direction of the bending part separately. The urethral anastomosis guide has the beneficial effects that the guide can be used for greatly reducing the difficulty of bladder neckurethral anastomosis. Due to the existence of the grooves, the positions of needles in and out are fixed, the suture distribution positions are relatively uniform, involution of the urethral mucosa and the bladder mucosa is well, and situations such as urine leakage or anastomotic stoma stenosis due to poor mucosal involution are prevented after surgery.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a urethral anastomosis guide. Background technique [0002] Prostate cancer is a common tumor of the male reproductive system. The incidence rate ranks first in developed countries in Europe and the United States, and it has risen rapidly in my country in recent years. Laparoscopic radical prostatectomy is the standard treatment for localized prostate cancer. In our hospital, more than 100 cases of radical prostatectomy are performed annually. The operation is complicated, and urethrovesical anastomosis is one of the difficulties. The difficulty in anastomosis is mainly due to the small space behind the pubic bone under the laparoscope, and the actions of holding, inserting, and withdrawing the needle are greatly restricted, and there are important organs and vascular plexuses in the anastomosis operation area, and inadvertent operation will cause bleeding and rectal inj...
