Abstract

The invention provides a pipeline connecting structure and an endoscope smoke circulating system, the pipeline connecting structure comprises a gas transmission and smoke exhaust instrument, the gas transmission and smoke exhaust instrument is provided with an instrument gas transmission channel and an instrument smoke exhaust channel which are isolated from each other, and the gas transmission and smoke exhaust instrument comprises an instrument connector and a pipeline assembly; the pipeline assembly comprises a gas conveying pipeline, a smoke exhaust pipeline and a pipeline joint, the pipeline joint comprises a joint disc and a plug connector protruding out of the joint disc, a gas conveying disc hole communicated with the gas conveying pipeline and a smoke exhaust disc hole communicated with the smoke exhaust pipeline are formed in the joint disc, the gas conveying disc hole is located in the plug connector, and the smoke exhaust disc hole is located outside the plug connector; the connector is provided with a connector smoke exhaust cavity, an inserting piece is inserted into the connector smoke exhaust cavity so that a gas pipeline can be communicated with the instrument gas exhaust channel, and meanwhile the smoke exhaust disc hole in the connector disc is opposite to the connector smoke exhaust cavity so that a smoke exhaust pipeline can be communicated with the instrument smoke exhaust channel. And the phenomenon that the reliability of gas circulation is affected due to the fact that plugging errors occur is prevented.

Description

Technical field [0001] The present invention relates to the field of medical devices, and more particularly to a line connection structure and a cavity mirror smoke cycle system. Background technique [0002] Minimally invasive laparoscopic surgery is a newly developed minimally invasive method, minimally invasive surgical treatment model is an inevitable trend in the development of future surgical methods. [0003] In minimally invasive laparoscopic surgery, common equipment includes a gasketing machine and a matching filter, and the air supply pipe is connected to the filter and the puncture, and the filter is mainly filtered by a CO2 gas output from the gas. After the gas pipeline enters the puncture to enter the abdominal cavity to maintain the pressure balance in the abdominal cavity; [0004] Specifically, in use, there is a need to connect both ends of the air supply conduit to the filter and puncture, the gas limb, and the gas is crude through the gas, after filtering, af...
