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.

Embodiment 1

[0020] Example 1: Micro-incision laparoscopic cholecystectomy

[0021] Make a 10mm incision below the umbilical cord, insert a double sheath cannula, connect the left air inlet 6 and / or right air inlet 6' to the laparoscopic trachea and establish pneumoperitoneum, insert a 5mm laparoscope through the left sheath 4, and then Under direct vision, make a 2mm micro-incision under the xiphoid process, and insert the electrocoagulation needle. After going out of the body, use a needle holder to bend the needle tip in 3 folds at 90 degrees to form an electrocoagulation hook, and then return it to the abdominal cavity; make a 2mm microincision in the right upper abdomen and insert a 2mm grasping forceps to pull the gallbladder to a suitable position; use the electrocoagulation hook to dissect the gallbladder Triangular, the cystic artery and cystic duct are dissected out. After the electrocoagulation needle is used, it can be pulled out from the 2mm micro-incision under the xiphoid pr...

Embodiment 2

[0022] Example 2: Microincision Laparoscopic Appendectomy

[0023] Make a 10mm incision below the umbilical cord, insert a double sheath cannula, connect the left air inlet 6 and / or right air inlet 6' to the laparoscopic trachea and establish an insufflation, and insert a 5mm laparoscope from the left sheath 4; Under direct vision, make a 2mm microincision at the level of the umbilicus on the right abdomen, insert the electrocoagulation needle, and under direct vision under the laparoscope, protrude out of the body through the right sheath 4', and bend the needle tip 3 into a hook-shaped electrocoagulation hook with a needle holder , stretched back into the abdominal cavity; made a 2mm micro-incision in the lower abdomen, inserted 2mm grasping forceps, and pulled the appendix to a suitable position; dissected the mesappendix with an electric coagulation hook, dissected out the appendix artery, and inserted an absorbable 4' from the right sheath Clamp the appendix artery, inser...

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 ...
