T-shaped cannula matched with sperm duct and working method of T-shaped cannula

Abstract

The invention relates to a T-shaped cannula matched with a sperm duct and a working method of the T-shaped cannula. The T-shaped cannula comprises a first pipeline, a second pipeline perpendicular tothe first pipeline is arranged in the middle of the first pipeline, the first pipeline communicates with the second pipeline, and barbs towards the first pipeline are arranged on the second pipeline.The T-shaped cannula disclosed by the invention is reasonable in structure and easy and convenient to operate, can effectively support the sperm duct and an epididymal duct, and can prevent the problem of narrow cavities of the sperm duct and the epididymal duct after an operation; and the recanalization rate is improved.

Description

technical field [0001] The invention relates to a T-shaped casing matched with the vas deferens and a working method thereof. Background technique [0002] With the development of microsurgical techniques and the wide application of microsurgical operations in andrology, many patients with spermatic tract obstruction had the possibility of recanalization through microsurgical operations, which made these patients have the possibility of fertility. Microscopic andrology surgery includes microscopic varicocele ligation, microscopic spermatic cord-epididymostomy, microscopic vasovasostomy, and microscopic sperm retrieval. It is a diversion and recanalization operation, which is to transect the vas deferens at the distal end of vas deferens obstruction, and then cut the epididymis and perform end-to-side anastomosis, and use 11-0 thread single needle or double needle method to anastomose the epididymis and vas deferens under the microscope. There are usually the following disad...

[0002] With the development of microsurgical techniques and the wide application of microsurgical operations in andrology, many patients with spermatic tract obstruction had the possibility of recanalization through microsurgical operations, which made these patients have the possibility of fertility. Microscopic andrology surgery includes microscopic varicocele ligation, microscopic spermatic cord-epididymostomy, microscopic vasovasostomy, and microscopic sperm retrieval. It is a diversion and recanalization operation, which is to transect the vas deferens at the distal end of vas deferens obstruction, and then cut the epididymis and perform end-to-side anastomosis, and use 11-0 thread single needle or double needle method to anastomose the epididymis and vas deferens under the microscope. There are usually the following disadvantages: 1. The anastomosis operation takes a long time; 2. The operator has high requirements for micromanipulation; 3. There is a certain failure rate after the anastomosis; 4. The operator has a long learning period and needs a period of special training.
