Description

A kind of vas deferens fixed cutting forceps

technical field

The invention relates to the technical field of medical equipment, in particular to a vas deferens fixation incision forceps.

Background technique

Obstructive azoospermia refers to the normal spermatogenesis function of the testis, and the obstruction of the vas deferens makes the transportation of sperm obstructed, resulting in no sperm in the semen. According to relevant reports, the incidence of obstructive azoospermia is about 1%. , accounting for 10-15% of male infertility.

Obstructive azoospermia can be treated with vasoepididymis microanastomosis or vasovasostomy, and the vas deferens needs to be fixed and flatly transected during the operation. However, there are following defects and deficiencies in the prior art when carrying out the above-mentioned operations:

First of all, the vas deferens is a tubular and peristaltic tissue, which cannot be completely and firmly grasped with the incision forceps in the prior art, and repeated operations are required, which affects the efficiency of the operation.

Secondly, after the vas deferens is grasped by the incision forceps, it is necessary to cut off the vas deferens with a scalpel, and the incision forceps in the prior art do not have a guide device specially matched with the scalpel, which makes it difficult for the operator to cut and cut off the vas deferens , The section of the vas deferens is not neat, which affects the success rate of anastomosis.

In addition, because the incision forceps need to assist the scalpel to cut the vas deferens, the process of cutting the vas deferens is a force-bearing process, and this force will affect the clamping effect between the vas deferens and the incision forceps, which may easily lead to the vas deferens slipping, which is not available in the current technology Aiming at this problem, a corresponding auxiliary fixing device is designed.

Furthermore, the size specification of the incision forceps in the prior art is single, and the size of the vas deferens of different human bodies is different. Using the same size of incision forceps to process the vas deferens cannot be suitable for different sizes, and it is easy to damage the vas deferens.

Chinese patent document CN201620638685.7, application date 20160622, the patent name is: a new type of vas deferens fixer, which discloses a new type of vas deferens fixer, including a first connecting rod and a second connecting rod, a first connecting rod and a second connecting rod The inner ends of the rods are respectively provided with hinged holes, the first connecting rod and the second connecting rod pass through the two hinged holes through the hinged screw and are screwed with nuts to realize fastening connection, the outer ends of the first connecting rod and the second connecting rod are respectively The vas deferens fixation forceps are fixedly arranged, and the vas deferens fixation forceps include successively connected pressing parts, intersecting parts and clamping parts, and the clamping parts include two symmetrically arranged clamping arms, both of which are straight, and two The inside of the clamping arm is provided with engaging clamping serrations, the plane defined by the first connecting rod and the second connecting rod is a reference plane, and the two clamping arms are respectively perpendicular to the reference plane and located on the same side of the reference plane.

The vas deferens fixer of the above-mentioned patent documents fills the blank of the vas deferens fixer in China. It is simple in structure, convenient and practical, reliable in grip, can effectively protect the lumen of the vas deferens, and increase the success rate of deferens reconstruction. However, there is no corresponding disclosure about a technical solution that can completely and firmly grasp the vas deferens, has guiding cutting and assisting fixation, and avoids damage to the vas deferens.

To sum up, there is a need for a fixed incision forceps that can completely and firmly grasp the vas deferens, guide cutting and assist fixation, and avoid damage to the vas deferens. However, there is no report about this fixed incision forceps.
