Laparoscopic surgery casing hole stitching device

Abstract

The invention relates to surgery operation apparatus which is special for stitching casing holes at the end of laparoscopic surgeries. Due to the small diameter of the casing hole and the deep hole, the sewing is difficult. We designed a casing hole stitching device to easily and accurately suture the casing holes. The invention comprises: (1) a hook part: a hook is made of metal, the head end is1.2cm wide and 1.5cm long, the hook back is 2cm high, and a window about 0.8X2.5cm is at the hook head and the hook back, the position is covered by a thin layer of silica gel. The hook is 18cm long.(2) a needle part: a curved needle with a diameter of 1.5 mm and a length of 7 cm, the needle tip section is designed with a "u" shaped groove. Pulling hook and bending needle operation process: the pulling hook is placed on the side of the abdominal wall; the seton at the tip of the bending needle enters from the middle of the casing hole and passes through the special pull hook silicone membraneat the bottom of the casing hole. When the needle is withdrawn along the original path, the thread it is brought into is detached from the needle, and the silicone film portion of the hook clamps thethread. The thread caught at the silicone membrane is brought out together when the pulling hook is taken out.

Description

technical field [0001] The invention relates to a surgical instrument, which is specially designed for suturing the cannula hole after pulling out the cannula at the end of the laparoscopic operation. The tube hole is well sutured and closed, reducing and avoiding the occurrence of trocar hole hernia after operation, and improving the quality of laparoscopic surgery. Background technique [0002] Near the end of laparoscopic surgery, when the cannula at the linea alba around the umbilical cord is pulled out, a cannula hole with a diameter of 10-12 mm needs to be sutured. It is usually distributed on both sides of the abdomen, and there is no need to suture the hole in the part with abdominal muscle structure, because the abdominal muscle rebounds after the cannula is pulled out, which can naturally close the cannula hole. The casing holes located above and below the navel must be sutured, because once the alba fascia is poked open, the defect left cannot rebound and heal. ...

AI Technical Summary

Problems solved by technology

The casing holes located above and below the navel must be sutured, because once the alba fascia is poked open, the defect left cannot rebound and heal

Clinically, in thinner patients, it is easier to suture this hole

However, in obese patients, due to the small diameter of the hole (usually 10-12mm) and the deep hole (often up to 4-7cm), it is difficult to suture the hole, and some are very difficult

Often due to inaccurate suturing, trocar hole hernia occurs after operation, which brings new pain to patients
