Semicircular working sleeve for single-hole laparoscope

Abstract

The invention relates to a medical minimally invasive operation instrument, in particular to a semicircular working sleeve for a single-hole laparoscope. The semicircular working sleeve comprises a handle and a sheath connected with the handle, wherein the end face of the handle is provided with a plurality of channels, an air filling valve and an air inlet valve; the air filling valve is communicated with an air path of an inflatable air bag arranged on the concave surface at the inner side of the sheath; and the air inlet valve is connected with a carbon dioxide gas source. The semicircular working sleeve is characterized in that the handle, the sheath and the inflatable air bag form a semicircular shape. The invention has the advantages that the semicircular design of the end face of the handle increases the area and the space position for placing the plurality of channels, and a plurality of instruments can be put in; the semicircular sheath has small injuries to the abdominal wall during entering the abdominal cavity through the abdominal wall and is beneficial to the healing of an incision, and an instrument activity space is obviously increased; the port of a silicone tube is covered by an elastic soft material so as to ensure that the semicircular working sleeve for a single-hole laparoscope is easy to enter the incision of the abdominal cavity and have small resistance; and the end face of the handle forms a fusiform design. The invention can also be applied to operations with larger operation difficulties, such as rear abdominal cavity operations, front abdominal cavity operations, and the like.

Description

technical field [0001] The invention relates to a minimally invasive surgical equipment, in particular to a semi-circular working sleeve for single-hole laparoscopy. Background technique [0002] Laparoscopic technology uses puncture or small incision in the patient's abdominal wall, inserts laparoscopic instruments from the puncture working sleeve, fills the abdominal cavity or extraperitoneal cavity with gas, and completes the operation of removing or repairing organs under TV monitoring. Laparoscopic technology is An important milestone in the history of medical development in the 20th century. [0003] In 1979, laparoscopic technology was applied to urology. To complete laparoscopic operation, at least three puncture working sleeves should be inserted in the abdominal wall. For example, total cystectomy requires five working sleeves to be punctured in the abdominal wall, and multiple puncture working sleeves will cause great damage to the patient's abdominal wall, and t...

AI Technical Summary

Problems solved by technology

However, the single-hole laparoscopic working sleeve is circular, and the operation of the instruments is inconvenient and hinders each other. Moreover, because the third instrument cannot be placed, the surgical method and type of surgery are greatly restricted, and the operation is difficult and technically demanding. complete complex surgery
