Abstract

The invention discloses an expansion device for ejaculatory duct obstruction, comprising a seminal vesicle probe tube capable of being inserted into the ejaculatory duct, an axially extending isolation plate is arranged in the seminal vesicle probe tube, and the isolation plate separates the inner cavity of the seminal vesicle probe tube into an observation cavity and an expansion chamber The tube is placed in a cavity, the front end of the observation cavity is equipped with a high-transmission objective lens, and the high-transmission objective lens is connected to the central processing unit through a visible optical fiber. The expansion device for ejaculatory duct obstruction also includes an expansion tube and a push rod. The expansion tube is a flexible tube made of degradable materials. The tube wall of the expansion tube is provided with a number of through holes that penetrate the inside and outside of the tube wall, and the outer tube of the expansion tube is provided. The wall is also provided with several swelling protrusions made of water-absorbing swelling material.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an expansion device for ejaculatory duct obstruction. Background technique [0002] The obstruction of the ejaculatory duct is the obstruction of the distal testis of the seminal duct. The causes are congenital and acquired, and the obstructive infertility caused by it accounts for about 1%-5% of male infertility. The main clinical symptoms are ejaculation pain, blood sperm, scrotal pain, perineal discomfort, chronic pelvic pain, ejaculation fatigue, low semen volume and abnormal urethral opening. A small number of patients may be combined with epididymitis or seminal vesiculitis. However, the traditional transurethral ejaculatory duct incision has obvious defects. This operation often needs to use electric cutting to cut the spermatozoa. During the operation, it is necessary to master the depth and scope of the electric incision, and observe whether the surgi...
