Embodiment Construction

[0022] The present invention will be further described below in conjunction with the drawings.

[0023] Such as figure 1 As shown, the tooth-opening laparoscopic pneumoperitoneum device of the present invention is composed of a cylindrical rack 1, a locking nut 2, a support tube 3, a connecting ring 4, and a variable cross-section spoke 5. The cylindrical rack 1 passes through the support tube 3 The center hole is installed, the lock nut 2 is sleeved on the upper part of the cylindrical rack 1, and the variable cross-section spokes 5 are installed in the groove at the lower end of the support cylinder 3 through the connecting ring 4, and are in a vertical position. This is the initial state of work.

[0024] Working principle and process:

[0025] When working, lift the abdominal wall, make an incision of about 30mm at the umbilical ring, hold the support tube 3, figure 1 The tooth-open laparoscopic pneumoperitoneum device shown in the initial working state is inserted into the abdom...

Abstract

A pneumoperitoneum-free device for a gear open type laparoscope comprises a cylindrical rack, a support cylinder, variable-section spokes, a connecting ring and a locking nut. The cylindrical rack is nested into the hollow part of the support cylinder. A groove is formed on the periphery of the lower end face of the support cylinder. The variable-section spokes are mounted in the groove. The gears on the variable-section spokes are meshed with the cylindrical rack. The variable-section spokes spread on the inner abdominal wall in the abdominal cavity by the engaging force of the gears on the variable-section spokes and the cylindrical rack, the front abdominal wall is lifted sufficiently, the spread variable-section spokes form a spherical crown, and accordingly the problem that the existing pneumoperitoneum-free surgeries are insufficient in exposed space, poor in abdominal wall stress condition, and easily causes secondary damage is solved.

Description

Technical field: [0001] The invention relates to the technical field of medical equipment, in particular to a tooth-opening laparoscopic pneumoperitoneum-free device. Background technique: [0002] As a minimally invasive technique, laparoscopic surgery has become an important surgical method for tissues and organs such as liver, gallbladder, pancreas, spleen, stomach, intestine, abdominal wall hernia, uterus and ovaries. Traditional laparoscopic surgery uses CO 2 Pneumoperitoneum technology to create surgical operation space. Due to CO 2 Pneumoperitoneum has many adverse effects on the breathing, circulatory system and pregnant fetus. Various abdominal wall suspension devices have been developed to perform laparoscopic surgery without pneumoperitoneum. However, the existing pneumoperitoneum techniques all have the disadvantages of insufficient operating space exposure and poor abdominal wall stress, which can easily cause secondary injuries. The main reason is that the abdomin...
