Cavity smoke eliminating device for abdominal operation

Abstract

The invention belongs to the technical field of medical equipment, and particularly relates to a cavity smoke eliminating device for abdominal operation. The cavity smoke eliminating device comprises a suction mechanism and a smoke filtering mechanism, wherein the smoke filtering mechanism comprises a fixing shell, the inner wall of the fixing shell is in threaded connection with a filtering cylinder, a filtering pipe is arranged on the inner wall of the bottom of the filtering cylinder, filtering openings are formed in the outer wall of the periphery of the filtering pipe, filtering elements are arranged on the inner walls of the filtering openings, a first through hole is formed in the outer wall of one side of the fixing shell, an air inlet is connected to the inner wall of the first through hole in an inserted mode, one end of the air inlet is connected with a smoke guiding pipe in a sleeved mode, the end, away from the air inlet, of the smoke guiding pipe communicates with the filtering pipe, a second through hole is formed in the outer wall of the other side of the fixing shell, and an air outlet is connected to the inner wall of the second through hole in an inserted mode. According to the invention, harmful smoke can be effectively eliminated, smoke filtering effect is good, it can be guaranteed that the air environment of an operating room is clean, and the device can adapt to various operation environments.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a device for eliminating smoke in an abdominal operation cavity. Background technique [0002] At present, hemostatic equipment such as electric knife and ultrasonic knife are commonly used in laparoscopic surgery in hospitals. During the operation, smoke, aerosol fog and various harmful gases will be generated. If these fumes are not sucked out in time, the mirror surface will be fogged, which will affect the clear vision and hinder the smooth progress of the operation. The smoke is directly discharged into the air, which can easily cause air pollution in the operating room and damage the health of surgical personnel. [0003] The existing smoke exhaust methods commonly used in clinical practice are the open smoke exhaust through the side hole of the operating sheath of the trocar, or the closed smoke exhaust method using the aspirator. These methods cannot solve the ...

Problems solved by technology

[0004] Based on the existing smoke exhaust methods commonly used in clinical practice, the side hole of the operating sheath of the puncture device is open to exhaust the smoke, or the airtight smoke exhaust method is used by the aspirator. The continuity of the operation is interrupted, and the problem of handling after the smoke is collected, the present invention proposes a smoke elimination device for abdominal surgery cavity
