Abstract

The invention relates to the technical field of ejaculatory duct stents, especially to a disposable anti-falling ejaculatory duct stent. The disposable anti-falling ejaculatory duct stent comprises astent body; the top end of the stent body is connected with a seminal vesicle inside curved pipe; a drainage side-hole is formed in the surface of the top end of the stent body; and one end, away fromthe seminal vesicle inside curved pipe, of the stent body is connected with a connecting half tube. According to the invention, the seminal vesicle inside curved pipe and the connecting half tube arearranged; the stent body is integrally and conveniently fixed in the seminal vesicle through the seminal vesicle inside curved pipe; through the drainage side-hole, the seminal vesicle fluid can be drained; the stent body can be effectively and conveniently bent through the connecting half tube; by arranging a first fixing ring and a second fixing ring and inserting a limiting block into a limiting groove, the first fixing ring and the second fixing ring can be limited on the surface of the connecting half tube, and therefore the situation that placement of the stent body is affected due to movement of an inner guide wire can be prevented.

Description

technical field [0001] The invention relates to the technical field of ejaculatory tube stent tubes, in particular to a disposable ejaculatory tube stent tube that prevents falling off. Background technique [0002] The ejaculatory duct is the channel through which males transport sperm. The ejaculatory duct is about 2cm long and penetrates the prostate parenchyma and opens in the prostatic urethra. It is composed of mucous membrane, sarcolemma and fibrous membrane. When the ejaculatory duct needs treatment, it is generally observed with seminal vesiculoscopy. Seminal vesiculoscopy is widely used in clinical practice, and is often used for refractory hemospermia, seminal vesicle stones, Seminal vesicle cyst, ejaculatory duct obstruction examination and treatment, ejaculatory duct obstruction is one of the causes of severe infertility or azoospermia, seminal vesiculoscopic technique will use ejaculatory duct stent for support after treatment. [0003] However, when the exist...
