Smoke and negative pressure suction device and method for endoscopic surgery

Abstract

The invention discloses a smoke and negative pressure suction device and a smoke and negative pressure suction method for the endoscopic surgery, for solving the problems that in the prior art, the connection for two suction pipelines in the endoscopic surgery is complicated, and the blockage of the suction apparatus influences the operating process. The device and the method have the effects that the cost is saved, the pressure abnormity in the pipeline caused by the blockage of the suction apparatus can be prevented, and the surgery is smooth. The technical scheme is as follows: the device comprises a main pipeline and an auxiliary pipeline communicating with each other, wherein two ends of the main pipeline are connected with the negative pressure suction device and a suction apparatus, and the auxiliary pipeline is connected with an endoscope puncture device; an air inlet hole is formed in the main pipeline, and pressure abnormity in the pipeline can be prevented through the air inlet hole.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a smoke and negative pressure suction device and method for endoscopic surgery. Background technique [0002] With the development of minimally invasive techniques, laparoscopic surgery is widely used due to its characteristics of less surgical injury, less pain, less scarring, and faster recovery. However, during the operation, the use of electrocoagulation hemostats and other equipment often produces strong and pungent coke smoke, which not only affects the clarity of the field of vision during the operation, but also has a certain impact on the operation process. Threats to the health of surgical medical staff. [0003] At present, in order to solve the smoke problem in endoscopic surgery, it is often necessary to connect two suction pipelines, which are respectively connected to the exhaust hole of the endoscopic trocar and the suction device, which is a cumbersome process and...

AI Technical Summary

Problems solved by technology

However, during the operation, the use of electrocoagulation hemostat and other instruments often produces strong smelling and pungent burnt smoke, which will not only affect the clarity of the field of vision during the operation, but also have a certain impact on the operation process. Threat to the health of surgical medical staff

[0003] At present, in order to solve the smoke problem in laparoscopic surgery, it is often necessary to connect two suction lines to connect the vent hole of the laparoscopic puncture device and the suction device respectively, which is cumbersome and will increase medical costs

Blockage will also occur during the suction of smoke by the suction device, which will cause abnormal pressure in the pipeline and affect the surgical effect

[0004] To sum up, in the prior art, there is still no effective solution to the problem of how to reduce the smoke in laparoscopic surgery and avoid abnormal pressure in the pipeline without increasing medical costs.
