Kits for Micro-incision Laparoscopic Surgery

Abstract

The invention discloses a kit for micro-incision laparoscopic surgery. The kit includes an electrocoagulation needle and a double sheath cannula. The sheath tube, the left sheath tube and the right sheath tube are both semicircular pipes, the two arc surfaces are opposite and hinged at the top by a hinge, the left side of the upper end of the left sheath tube is provided with a left air inlet, and the right sheath tube The right side of the upper end of the upper end is provided with a right air inlet, the left sheath above the left air inlet is provided with a left anti-leakage valve, and the right sheath above the right air inlet is provided with a right anti-leakage valve; The electrocoagulation needle includes a needle tail and a needle point, and the needle tail is connected with an electrocoagulation wire. Cooperating with the electrocoagulation needle and the double sheath cannula of the present invention, only one incision of 10 mm and one or two 2 mm incisions are required. On the premise that the difficulty of the operation does not increase significantly, the incisions are few and small, and the 2 mm incisions are restored. Incision scars are barely visible, and patients experience significantly less postoperative incision pain.

Description

technical field [0001] The invention relates to a laparoscopic surgical instrument, in particular to an electrocoagulation needle and a double sheath cannula which are used together in micro-incision laparoscopic surgery. Background technique [0002] At present, laparoscopic surgery is becoming more and more common clinically. Compared with traditional open surgery, it has the advantages of small incision and fast postoperative recovery. Among them, the most common one is laparoscopic cholecystectomy, which has replaced traditional open surgery. Abdominal cholecystectomy has become the standard procedure for the treatment of benign gallbladder diseases such as gallstones. With the advancement of society, people have higher and higher requirements for postoperative quality of life. One of them is the concern for abdominal surgical scars, requiring laparoscopic surgery with smaller scars or even no scars at all. In most laparoscopic operations at present, two incisions with ...

Problems solved by technology

For example, transumbilical single-port laparoscopic surgery combines the main operation port, observation port and auxiliary operation port into the subumbilical incision, but this operation needs to expand the subumbilical incision to about 20mm, which fails to meet the cosmetic requirements. In this operation, the main operation hole and the auxiliary operation hole are moved to the position below the navel, away from the operation area, and the operation with the lens interferes with each other, which greatly increases the difficulty of the operation and significantly prolongs the operation time.

Laparoscopic surgery through natural orifice, including gastroscopic transgastric surgery, transvaginal laparoscopy and transrectal laparoscopic surgery, although surgical scars are avoided, but laparoscopic surgery through natural orifice is more difficult and involves the patient's private parts, so it is difficult to provide Patients accept, while the possibility of intra-abdominal bacterial infection is also greatly increased

Therefore, both transumbilical single-port laparoscopy and natural port laparoscopy have the disadvantages of difficult operation, long time, and high surgical technical requirements. They are only carried out in large medical centers and are difficult to be widely promoted.
