Double-barrel type gasless abdominal single-aperture operating platform used for laparoscopic surgery

Abstract

A double-barrel type gasless abdominal single-aperture operating platform used for a laparoscopic surgery consists of a single-aperture channel, a suspension umbrella, a mechanical arm and a fixing pole, wherein the single-aperture channel is connected with the suspension umbrella by joints; the suspension umbrella is suspended on the mechanical arm; and the mechanical arm is arranged on the fixing pole. The single-aperture channel consists of a main pipe and a lengthened pipe, a perforated disk through which surgical equipment can pass is arranged in the middle of the interior of the main pipe of the single-aperture channel, the suspension umbrella consists of a spoke, a push-pull pipe, a needle core and a chain, and the spoke is folded towards the center through the near-end joint, the far-end joint and the middle joint to form the umbrella shape when the push-pull pipe slides downwards. According to the invention, the laparoscopic single-aperture technology and the gasless technology are combined organically, thereby overcoming the defects in the existing surgery adopting the gasless technology that the space is small and the exposure of the surgery field is poor, and simplifying the operation of the laparoscopic single-aperture gasless abdominal surgery, so that the double-barrel type gasless abdominal single-aperture operating platform can be promoted and applied easily.

Description

[0001] technical field [0002] The invention relates to the field of laparoscopic minimally invasive surgery, in particular to a double-tube pneumoperitoneum-free single-hole operating platform for laparoscopic surgery. Background technique [0003] 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. Laparoscopic surgery routinely utilizes 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 technologies include the Japanese "Kirschner wire" pneumoperitoneum-free device represented by Shanghai Island Medical Group, the ...
