Electrocoagulation needle used for microincision laparoscopic surgery and double-sheath sleeve

Abstract

The invention discloses an electrocoagulation needle used for microincision laparoscopic surgery and a double-sheath sleeve. The double-sheath sleeve comprises a left sheath and a right sheath which are same in size and arranged symmetrically, the left sheath and the right sheath are all semicircular tubes, the arc faces of the left sheath and the right sheath are arranged oppositely and hinged with each other through a hinged chain at the upper portions of the left sheath and the right sheath, the left side of the upper end of the left sheath is provided with a left air inlet, the right side of the upper end of the right sheath is provided with a right air inlet, the portion, arranged above the left air inlet, of the left sheath is provided with a left leakage-proof valve, and the position, arranged above the right air inlet, of the right sheath is provided with a right leakage-proof valve. The electrocoagulation needle comprises a needle tail and a needle tip, and the needle tail is connected with an electrocoagulation wire. By using the electrocoagulation needle and the double-sheath sleeve in a matched mode, only one 10 mm incision and one to two 2 mm incisions are needed, on the premise that the surgical difficulty is not improved obviously, the number of incisions is low, the incisions are small, after the 2 mm incisions are recovered, incision scars are nearly invisible, and the degree of incision pain of a patient after the surgery is greatly lowered.

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.
