Embodiment Construction

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

[0023] Such as figure 1 As shown, the open-toothed laparoscope-free pneumoperitoneum device of the present invention is composed of a columnar rack 1, a lock nut 2, a support tube 3, a connecting ring 4 and a variable-section spoke 5, and the columnar rack 1 passes through the support tube 3. The central hole is installed, the lock nut 2 is set on the top of the columnar rack 1, and the variable-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, and place the figure 1 The open-toothed laparoscope-free pneumoperitoneum device shown in the initial working state is inserted...

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 devices, in particular to an open-tooth laparoscope-free pneumoperitoneum 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 ovary. Traditional laparoscopic surgery using CO 2 Pneumoperitoneum technique to create surgical operation space. Due to CO 2 Pneumoperitoneum has many adverse effects on breathing, circulatory system and pregnant fetus. Various abdominal wall suspension devices have been developed to perform laparoscopic surgery without pneumoperitoneum. However, the existing pneumoperitoneum-free techniques have the disadvantages of insufficient exposure of the surgical space and poor stress on the abdominal wall, which may easily cause secondary injuries. The main reason is that t...
