Abstract

The invention relates to a T-shaped sleeve matched with a vas deferens and a working method thereof. The invention has reasonable structure and simple and convenient operation, can effectively support the vas deferens and the epididymis duct, can prevent the problem that the vas cavity of the vas deferens and the epididymis duct is narrow after operation, and improves the recovery rate.

Description

T-shaped sleeve matched with vas deferens and working method thereof

Technical Field

The invention relates to a T-shaped sleeve matched with a vas deferens and a working method thereof.

Background

With the development of microsurgery technology and the wide application of microsurgery operation in andrology, many patients with obstruction of the spermatic tract have the possibility of microsurgery operation recovery, so that the patients have the possibility of fertility, the conventional microscopical andrology operation is carried out by operations such as spermatic varicocele ligation under a microscope, spermatic cord-epididymis anastomosis under a microscope, spermatic duct anastomosis under a microscope, microscopic semen collection and the like, the common epididymis-spermatic duct anastomosis under a microscope is a diversion recovery operation for obstructive azoospermia, the vas duct is transversely cut at the far end of obstruction of the vas duct, the epididymis duct is cut and then anastomosed at the end side, and the epididymis duct is anastomosed by using an 11-0 line single needle or a double needle method under a microscope, and the method has the following defects: 1. the anastomosis operation time is long; 2. the requirement on the micro-operation of an operator is high; 3. a certain disability rate exists after anastomosis; 4. the learning period of an operator is long, and special training needs to be carried out for a period of time.

Disclosure of Invention

In view of the above, the present invention provides a T-shaped sleeve matched with the vas deferens and a working method thereof, which have the advantages of reasonable structure and simple operation, can effectively support the vas deferens and the epididymis duct, can prevent the problem of the stenosis of the vas deferens and the epididymis duct after the operation, and can improve the recovery rate.

The technical scheme of the invention is as follows: the utility model provides a with vas deferens complex T type sleeve pipe, includes first pipeline, be provided with in first pipeline middle part with first pipeline vertically second pipeline, first pipeline and second pipeline intercommunication are provided with the barb towards first pipeline direction on the second pipeline.

Further, the first pipe has a diameter of 0.4mm and a length of 1 mm.

Further, the second pipe has a diameter of 2mm and a length of 3 mm.

Furthermore, the materials of the first pipeline and the second pipeline are both high-purity collagen.

The invention provides another technical scheme that the working method of the T-shaped sleeve matched with the vas deferens comprises the following steps: the end part of the disconnected spermaduct is sleeved on the end part of the second pipeline, the agnail can prevent the spermaduct from falling off, the epididymal duct is cut into a small opening, the first pipeline is plugged into the epididymal duct, the epididymal anastomosis of the spermaduct under a microscope is basically completed, and then the spermaduct and the epididymal serosal layer are sewn by using 11-0 silk threads.

Compared with the prior art, the invention has the beneficial effects that: the invention has reasonable structure and simple and convenient operation, can save operation time, can effectively support the vas deferens and the epididymis duct, can prevent the problem of narrow canals of the vas deferens and the epididymis duct after operation, and improves the recovery rate.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

Detailed Description

As shown in figures 1-3, a T-shaped sleeve matched with a vas deferens comprises a first pipeline 10, a second pipeline 20 perpendicular to the first pipeline 10 is arranged in the middle of the first pipeline 10, the first pipeline 10 is communicated with the second pipeline 20, and barbs 30 facing the first pipeline 10 are arranged on the second pipeline 20. The first tube 10 and the second tube 20 can be made in an integrated manner, and the barbs 30 can prevent the vas deferens 40 from falling off from the second tube 20 when in use.

In this embodiment, the first pipe 10 has a diameter of 0.4mm and a length of 1 mm.

In this embodiment, the second conduit 20 has a diameter of 2mm and a length of 3 mm.

In this embodiment, the materials of the first tube 10 and the second tube 20 are highly purified collagen.

A method of operating a T-shaped cannula for engagement with a vas deferens 40, comprising: the disconnected end of the vas deferens 40 is sleeved on the end of the second pipe 20, the agnail 30 can prevent the vas deferens 40 from falling off, the epididymal duct 50 is cut into a small opening, the first pipe 10 is plugged into the epididymal duct 50, the epididymal anastomosis of the vas deferens 40 under a microscope is basically completed, and then the vas deferens 40 and the serosal layer of the epididymal duct 50 are sewn by using 11-0 silk threads.

The above-mentioned operation flow and software and hardware configuration are only used as the preferred embodiment of the present invention, and not to limit the scope of the present invention, and all equivalent changes made by using the contents of the present specification and the drawings, or directly or indirectly applied to the related art, are included in the scope of the present invention.
