A laparoscopic knot pushing suture device

Abstract

The invention relates to a laparoscope suture knot pushing and suturing device. The device is characterized by comprising a guider (11) and a suturing probe (12); the opposite sidewalls of the guider are each obliquely provided with a guide hole (10), the two guide holes are staggered in the opposite directions of the guider, and the suturing probe is correspondingly matched with the guide holes in a guiding mode; the guider comprises a fixed sleeve, a pull rod (3) is connected into the fixed sleeve in a sliding fit mode, one side of the pull rod is connected with a locking handle (2), two movable wing plates (4) are hinged to the two symmetrical sides of the other end of the pull rod respectively, and a silicon thin film sheet (7) is arranged in each movable wing plate; the silicon thin film sheets are arranged on extension lines of the corresponding guide holes after the movable wing plates rotate. The laparoscope suture knot pushing and suturing device has the advantages of being reasonable in design, accurate in locating, ingenious in structure, easy to operate and capable of simplifying the suturing process; compared with a conventional suturing mode, the puncture hole suturing time is shortened obviously, so the laparoscope suture knot pushing and suturing device has an obvious safety function and will not hurt blood vessels in the body of a patient or potential visceral organs.

Description

technical field [0001] The invention relates to an abdominal wall suturing device for laparoscopic surgery, in particular to a laparoscopic thread knot pushing and suturing device. Background technique [0002] With the development and maturity of laparoscopic technology, diagnostic and therapeutic laparoscopy is widely used in the field of surgery. Due to the expansion of the scope of surgery and the increase in the difficulty of surgery, the types of surgical complications have also increased compared with the past. Puncture site hernia (Trocar Site Hernia, TSH), a rare surgical complication of laparoscopic surgery in the past, is gradually increasing, and the safety of laparoscopic treatment has attracted people's attention. [0003] At present, conventional surgical instruments are used to suture the incision at the abdominal wall puncture site in this field. Due to the small and deep puncture hole, the small operation field, and the large radian of the suture needle, i...

AI Technical Summary

Problems solved by technology

[0003] At present, conventional surgical instruments are used to suture the incision at the abdominal wall puncture site. Due to the small and deep puncture hole, the small surgical field, and the large radian of the suture needle, it is difficult to suture, and it is impossible to suture the peritoneal and fascial layers accurately.

Limited by conventional instruments and suturing methods, if the peritoneum and fascia layer cannot be closed when suturing the incision, the intra-abdominal omentum or intestinal tube may herniate into the incision gap to form an incisional hernia or local adhesions may lead to incomplete intestinal obstruction. It often causes puncture hole bleeding, delayed healing of puncture hole, puncture hole hernia, and other tissue planting in puncture hole. Complications increase the suffering of patients, increase medical expenses, and reduce the treatment effect
