Description

Technical Field

[0001] The utility model relates to the technical field of laparoscopic fallopian tube end-to-end automatic anastomosis device, in particular to a laparoscopic fallopian tube end-to-end automatic anastomosis device. Background Art

[0002] Tubal anastomosis is a surgical procedure that uses surgical techniques to suture the two ends of the ligated fallopian tube to restore the tubal canalization. It is a tubal repair surgery and an effective method for reconstructing the function of the reproductive system. Laparoscopic tubal anastomosis is a difficult operation because it requires good laparoscopic suturing techniques and good instruments and equipment. Conventional laparoscopic tubal serosal layer separation, surgical excision of the tubal scar, injection of diluted methylene blue solution from the uterine cavity to check the patency of the proximal end of the fallopian tube, insertion of an epidural anesthesia catheter from the umbrella end as a stent to check the patency of the distal end, and then insertion of the distal epidural anesthesia catheter into the proximal end, after the end-to-end anastomosis of the fallopian tube, 4 interrupted sutures with 5 / 0 absorbable sutures are performed. The suture order is generally 6 o'clock, 3 o'clock, 9 o'clock, and 12 o'clock of the tubal seromuscular layer. During the suture, the epidural anesthesia catheter is used as a support, and the sutures should not penetrate the tubal mucosa as much as possible. Then, the tubal serosal membrane is sutured with 4 interrupted stitches to bury the tubal anastomosis wound. After suturing, diluted methylene blue solution is injected through the uterine cavity. If methylene blue solution flows out of the fimbria of the fallopian tube, it indicates that the fallopian tube is unobstructed. However, the use of laparoscopic 5 / 0 absorbable sutures is difficult due to the small needle and fine thread. Precise operation increases the operation time and lacks structure for rapid and automatic suturing.

[0003] The current laparoscopic fallopian tube anastomosis has the following disadvantages:

[0004] (1) Use laparoscopic 5 / 0 absorbable sutures, which are difficult to sew with small needles and fine threads, increase the duration of the operation with precise operation, and lack the structure for rapid and automatic suturing;
