Integrated intra-cavity gas circulation processing device for laparoscopic surgery

Abstract

The invention provides an integrated intra-cavity gas circulation processing device for laparoscopic surgery. The device includes a filtering unit and a driving pump unit, the filtering unit is provided with a gas inlet channel, and the gas inlet channel communicates with a human abdominal cavity; the driving pump unit is arranged in the filtering unit, and communicates with the filtering unit; and the driving pump unit is provided with a gas discharge channel, and the gas discharge channel communicates with the human abdominal cavity. The integrated intra-cavity gas circulation processing device for the laparoscopic surgery provided by the invention realizes integrated arrangement of the filtering unit and the driving pump unit, has clever design, a compact structure, a small volume and asmall occupied space; and the device is convenient for medical workers to operate during the laparoscopic surgery, the stability of air pressure in the abdominal cavity is high and the gas circulation filtration effect is good the during the entire surgery, so that the device improves the surgical efficiency and quality, ensures that contaminated work pieces which cannot be disinfected (such as drive pumps) are not used repeatedly, and realizes true zero infection.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an integrated intracavity gas circulation processing device for laparoscopic surgery. Background technique [0002] With the advancement of laparoscopic surgery technology, laparoscopic minimally invasive surgery technology has been promoted. When electric knife equipment is used for cutting or electrocoagulation during surgery, a lot of smoke will be generated, which will blur the mirror surface of the endoscope. As a result, the display content transmitted to the monitor through the camera system becomes blurred, which is the most troublesome problem in laparoscopic surgery. Therefore, this smoke must be removed in time. [0003] The existing commonly used smoke removal method is to use the negative pressure equipment in the hospital to extract it. Most of the extracted smoke gas is CO2 and odorous smoke gas, which is directly discharged. This will not only cause ai...

Problems solved by technology

[0004] As can be seen from the above, the reflux suction device includes three filter parts (the first filter bottle 1, the second filter bottle 2 and the filter 3) and a driving part (piston pump 4), and the liquid and gas in the abdominal cavity are drawn by the piston pump 4. suction, and then filter through the first filter bottle 1, the second filter bottle 2 and the filter 3 in turn. When in use, the above-mentioned components are set independently of each other but communicated through each connecting pipe (5 / 6 / 7), so there will be The following defects: 1. The overall structure of the reflux aspirator is quite complex and cumbersome, with a large volume and a large space. During laparoscopic surgery, it is extremely inconvenient for medical staff to use and operate; There is a defect of poor connection sealing between the connecting pipes (5 / 6 / 7); 3. Multiple filtering parts and driving parts are connected and reused through connecting pipes (5 / 6 / 7), which leads to The problem of cross-infection of the filtered gas by bacteria again directly increases the risk of surgery
