Background

Laparoscopic surgery is a newly developed minimally invasive surgery and has the advantages of small surgical wound, low injury to patients and the like. Laparoscopic surgery requires the creation of an operative space in the abdominal cavity, which requires the infusion of gas into the abdominal cavity to raise the anterior abdominal wall for good vision and sufficient instrument space, which requires the use of a pneumoperitoneum machine. Pneumoperitoneum machine is one of the necessary medical instruments in laparoscopic surgery, and is used for delivering CO2 gas into the abdominal cavity of a patient and maintaining a certain pressure, so that a good visual field and a large enough operation space are provided for a main knife doctor. When an electric knife with high smoke generation is used for operation, the operation visual field is unclear, so that smoke absorption is required continuously, and a filter is required in the process of using a pneumoperitoneum machine to absorb smoke in laparoscopic operation.

The existing pneumoperitoneum machine and the filter are fixed in a mode that a button is pressed to release the filter. And a plurality of rebound structures are adopted, and torsion springs are utilized for resetting. And the existing pneumoperitoneum machine filter is complex in disassembly and assembly internal structure and is provided with a plurality of rebound points, as shown in fig. 1, the I position is a first rebound point, the II position is a second rebound point, and the stress is inconsistent with the resetting direction. The button is pressed down, so that the rebound device is easy to lose efficacy, and the rebound blocking phenomenon is generated. In surgery, the filter may be used twice, and the filter cannot be locked, so that the risk is high.
