Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a gas supply pipe heating device for a laparoscopic insufflator. Background Art

[0002] The pneumoperitoneum machine is a special device for establishing and maintaining pneumoperitoneum in laparoscopic minimally invasive surgery. Through the mechanical pressurization and inflation of the pneumoperitoneum machine, artificial pneumoperitoneum is established to separate the abdominal wall from the internal organs, providing sufficient operating space for surgery and avoiding damage to the internal organs when the puncture cannula penetrates the abdominal cavity. During minimally invasive abdominal surgery, high-purity carbon dioxide gas needs to be filled to make the abdominal cavity pressure reach 10-15mmhg, so that the operation can be performed safely and conveniently. The process of CO2 gas output from the gas cylinder is the process of converting liquid CO2 into gas. When used in surgery, it is decompressed and output to the pneumoperitoneum machine through the pressure reducing valve, and then the pneumoperitoneum machine controls the flow and pressure to deliver it to the patient's abdominal cavity. Although CO2 absorbs heat energy during the liquid / gas conversion, the output gas temperature is also very low. Due to the temperature difference between the gas and the abdominal cavity, water vapor condensation is easy to occur, which cannot meet the requirements of lens clarity. In addition, a large amount of low-temperature gas input into the abdominal cavity will cause the patient to have a risk of hypothermia. In the prior art, some pneumoperitoneum machines have built-in heating devices, but many hospitals have been carrying out laparoscopic surgery for a long time. The pneumoperitoneum machines purchased by the hospital in the early stage are not equipped with heating devices. If they continue to be used step by step, it is inconvenient for surgical personnel to operate the operation, and there is a risk of hypothermia in patients. If the problem of heating CO2 needs to be solved, new equipment needs to be replaced, which will increase the cost consumption of the hospital. For this reason, a laparoscopic pneumoperitoneum machine air supply pipe heating device is proposed. Utility Model Content
