Smoke Evacuation Heating Insufflator

Ⅰ. Subcutaneous emphysema Subcutaneous emphysema is the most common pneumoperitoneum complication, and the incidence of subcutaneous emphysema is as high as 2.7%. 1. Common reasons (1) Patient factors: patient weight and thickness of subcutaneous fat are closely related to the occurrence of subcutaneous emphysema, mainly due to the lack of subcutaneous adipose tissue in extremely emaciated patients, the weak blocking effect of adipose tissue on gas, and the rapid diffusion of gas along the subcutaneous to form subcutaneous emphysema. (2) Puncture technique, pneumoperitoneum needle is located...

First, before the epidemic, many literatures reported that the aerosol produced by the smoke in the operating room contained many harmful components, which had certain adverse effects on the health of medical workers. In the epidemic period, the control of aerosol in the operating room is particularly important. The SAGES and EAES report highlights the following considerations for avoiding aerosol production during surgery: 1. Improve the awareness of protection: awareness determines behavior, and improving the awareness and prevention awareness of medical staff in the operating room is the...

1. It has been found that laser instrument, ESU and ultrasonic knife can vaporize complete tissue cells and blood components. 2.the study confirmed that these vaporized cells are still active, the lower the energy used by the instrument, the shorter the time used each time, the greater the probability of the presence of active cells in the surgical smoke. 3. Studies have found that certain electric surgical tools can vaporize HIV-containing blood, and the smoke produced contains active HIV, which can infect cultured human T cells. HIV DNA can remain active in the smoke produced by CO2 laser...
