The present invention relates to a comprehensive surgical clip for improving vasectomy and an operating method thereof, comprising a comprehensive surgical clip; the comprehensive surgical clip comprises two clamps for clamping and fixing the two ends of the vas deferens, the two clamps being connected to the same scissors structure and being synchronously opened and closed by the scissors structure; and further comprising: a syringe, which is obliquely and slidably arranged on the comprehensive surgical clip and is used for injecting a mixed liquid into the vas deferens and promoting the discharge of semen. The present invention has a compact and reasonable structure and is easy to operate. By adopting a special surgical clip and a specific operating technique, work efficiency is improved. At the same time, on the basis of traditional vasectomy surgery, a special flushing technology is added to improve the efficiency of residual semen discharge, greatly shortening the patient's postoperative contraception time compared with traditional surgery, and can also judge the patency of the vas deferens according to the color of the discharged semen, providing preoperative evaluation guidance for some patients who need to restore fertility and undergo vasectomy.

Contraceptives and methods for reversible male birth control are disclosed herein. One method includes providing a polymer including a viscosity and reducing the viscosity of the polymer to create a polymer solution. The method further includes injecting the polymer solution into the vas deferens of a male subject while the viscosity of the polymer is reduced. The polymer solution forms a polymer barrier in the vas deferens to physically block the outflow of sperm in the vas deferens subsequent to injection.

The present invention introduces a groundbreaking solution in the field of male contraception-a reversible male birth control implant device. The device offers enhanced flexibility in family planning by controlling the amount of sperm ejaculated. It consists of a tubular component surgically inserted into each severed vas deferens, with a wireless receiver attached. The wireless receiver receives external wireless signals and enables the device to switch between a state that permits the flow of sperm and a state that impedes it. The device also features an outlet for the safe elimination of obstructed sperm. The use of biocompatible materials and compatibility with medical imaging devices, such as MRI, ensures safety and usability. This innovative device empowers individuals with convenient and discreet control over their fertility, revolutionizing male contraception and opening new possibilities in reproductive health.

The utility model relates to the technical field of veterinary inseminating inseminating inseminating inseminating inseminating inseminating inseminating inseminating inseminating inseminating inseminating inseminating inseminating inseminating inseminating inseminating inseminating inseminating inseminating inseminating inseminating inseminating inseminating inseminating inseminating inseminating inseminating inseminating inseminating inseminating inseminating inseminating inseminating inseminating inseminating Even if the low-temperature wax melts in advance due to the influence of high temperature, the seminal fluid is protected by a gel layer, so that the seminal fluid can be effectively prevented from overflowing in advance.

The invention relates to a device for controlling a flow circulating in the lumen of a male vas deferens, comprising a clamp configured to coaxially grasp an outer wall of the vas deferens and a long, slender element coupled to the clamp, a distal portion of which is adapted to be at least partially inserted into the vas deferens. Said distal portion has a deflection tube adapted to divert said flow out of the vas deferens when an inlet of said deflection tube is aligned with the lumen. Abstract figure: Fig. 1

Delivery systems for providing occlusive hydrogels in a tube lumen or void space within the body including but not limited to a reproductive tract such as the vas deferens or fallopian tubes for contraception are described. The delivery systems contain mechanisms that confirm proper placement of the system in the bodily lumen prior to the delivery of the occlusive material. The systems also can contain a confirmatory mechanism that demonstrates the blockage or occlusion in the bodily lumen has been achieved following the deposition of the occlusive material. Another aspect of this application is to provide a removal system that delivers dissolving material, agitates, aspirates, and confirms the patency of the bodily lumen following the removal of the occlusive material if so desired by the patient for the return to fertility.

The application discloses a kind of built-in anti-ejaculation devices of stallion, it is related to the technical field of animal husbandry, including placing hose, support tube is placed in the inside of placing hose;The outer side wall of the open end of support tube is installed with snap ring, and the opposite surface of snap ring is installed with fixed assembly;One of snap ring is in abutment with the inner side wall of placing hose, and the other snap ring is in abutment with the opening of placing hose.The application discloses a kind of built-in anti-ejaculation devices of stallion, not only can realize the filtration of sperm of stallion, but also can make that tissue fluid can normally flow and avoid vas deferens congestion, and will not affect normal mating behavior of stallion, further, anti-ejaculation behavior is reversible, does not affect stallion recovery reproductive capacity in later period, overall built-in structure design is compact, fixed assembly is assembled firmly, can be long-term retained and used, no exposed component, safe and non-irritating, adapt to stallion physiological structure, and practicality is strong.

1. Name of the designed product: insemination tube (single tube). 2. Use of the designed product: insemination tube for veterinary use. 3. Design points of the designed product: in shape. 4. Picture or photo that best shows the design points: perspective view.

The application discloses a vas deferens contraceptive device and a preparation method thereof, and relates to the technical field of medical devices. The device comprises a tubular outer wall, the inside of the tubular outer wall is filled with a sperm blocking layer and a mechanical support layer, the sperm blocking structure is a pore structure that can block sperm, and the mechanical support structure is a three-period minimal surface structure. The combination of the two structures can prevent sperm from passing through the vas deferens while ensuring the normal passage of tissue fluid. The device is mainly prepared through three steps of model slice design, ink configuration, 3D printing and device post-processing. Compared with vasectomy, the vas deferens contraceptive device and the preparation method thereof can avoid complications and fertility damage caused by epididymal stasis, and the implantation of the device has a smaller incision than vasectomy and is convenient for processing and manufacturing.
