Embodiment 1

[0040] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a closed state structure of a vas deferens 8 fixed incision forceps of the present invention. A vas deferens 8 fixed incision forceps, the vas deferens 8 fixed incision forceps includes a ring 1, forceps arm 2, pin shaft 3, semicircular forceps head 4, cutting and positioning guide groove 5, pawl 6, convex point 7; There are two pincer arms 2, and the two pincer arms 2 are hinged by a pin shaft 3; one end of the pincer arm 2 is fixedly connected to the finger ring 1, and the other end of the pincer arm 2 is connected to the semicircular pincer head 4; The pin shaft 3 is set on the upper part of the middle part of the pliers arm 2, and the two ends are riveted with the surface of the pliers arm 2 for positioning; the pawl 6 is set on the lower section of the pliers arm 2; the cutting positioning guide groove 5 is perpendicular to the semicircular pliers The axis of the head 4, and the two ends ...

Embodiment 2

[0052] Please see image 3 , image 3 It is a schematic diagram of the use state of a vas deferens 8 fixed incision forceps of the present invention. The use state of the vas deferens 8 fixed incision forceps refers to operating the vas deferens 8 fixed incision forceps, closing the semicircular forceps head 4 of the vas deferens 8 fixed incision forceps to clamp the vas deferens 8, and the bumps 7 firmly fixing the vas deferens 8, Avoid its activity, facilitate the scalpel 9 to cut and break the vas deferens 8 along the cutting positioning guide groove 5. The two semicircular pliers 4 can be closed to completely grasp the vas deferens 8, and then use the lock of the pawl 6, which is convenient to operate, reliable in grip, easy to cut and disconnect the vas deferens 8, and the section of the vas deferens 8 is neat, which is convenient for anastomotic surgery and improves the efficiency of anastomotic surgery Success rate.

Abstract

The invention relates to a pair of vas deferens fixing incision forceps. The pair of vas deferens fixing incision forceps comprises finger rings, two forcep arms, a pin shaft, semicircular forcep heads, a cutting positioning guide groove, pawls and protruded points; the two forcep arms are hinged to each other by the pin shaft; certain ends of the forcep arms are fixedly connected with the fingerrings, and the other ends of the forcep arms are connected with the semicircular forcep heads; the pin shaft is arranged at a part slightly upper than the middle of each forcep arm, and two end facesof the pin shaft are riveted and positioned with the surfaces of the forcep arms; the pawls are arranged at lower sections of the forcep arms; the cutting positioning guide groove is perpendicular tothe axes of the semicircular forcep heads, and two ends of the cutting positioning guide groove equally divides through grooves of the semicircular forcep heads; the inner sides of the semicircular forcep heads are provided with the protruded points. The pair of vas deferens fixing incision forceps has the advantages of filling the blank of domestic vas deferens fixing incision forceps, being capable of completely and firmly grasping a vas deferens, achieving a guiding cutting effect, achieving an auxiliary fixing effect, and avoiding damage to the vas deferens.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a vas deferens fixation incision forceps. Background technique [0002] 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. [0003] 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: [0004] 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 ar...
