Full-automatic smoke exhausting and filtering system for minimally invasive surgery

Abstract

The invention discloses a full-automatic smoke exhausting and filtering system for minimally invasive surgery, which relates to the field of minimally invasive surgery, and comprises a host, a filter and a negative pressure suction pump, and further comprises a host, a display screen is fixedly arranged at the front end of the host, a button, a switch and a damping frame are arranged on the host on the same side of the display screen, and a pump mounting position is arranged on one side, far away from the display screen, of the host; a negative pressure suction pump is fixedly mounted in the pump mounting position, the damping frame is fixedly arranged between the negative pressure suction pump and the pump mounting position, the cleaning piece is movably mounted in the filter on one side where gas is sucked, a filtering layer is fixedly mounted in the filter, and the cleaning piece is arranged to be tightly attached to the filtering layer. Tissue fragments left after smoke filtration on the surface of the filtering layer are cleaned, the situation that the surface of the filtering layer hinders smoke circulation and weakens the filtering effect of the filtering layer is prevented, gas pressure in the abdominal cavity of a patient is kept dynamically balanced and stable, harm to medical workers is avoided, and the safety of an operation is improved.

Description

technical field [0001] The invention relates to the field of minimally invasive surgery, more particularly, to a fully automatic minimally invasive surgery smoke exhaust filter system. Background technique [0002] Surgical smog is a kind of pollution to the operating room environment. With the widespread use of energy-based active instruments such as electrosurgery, laser knives, and ultrasonic knives in surgery, the hazard of smog must be paid attention to. [0003] Surgical smoke is the smoke formed by the destruction and vaporization of the patient's tissue protein or fat under the action of high-energy instruments. The smoke is composed of water vapor and cell debris. The main components of cell debris include: blood and tissue debris, active virus, active Cells, harmful chemical components, inactive cells, mutagenic substances, and some small active virus cells can directly enter the human respiratory system and alveoli. Long-term exposure to mutagenic substances can c...

[0003] Surgical smoke is the smoke formed by the destruction and vaporization of the patient's tissue protein or fat under the action of high-energy instruments. The smoke is composed of water vapor and cell debris. The main components of the cell debris are: blood and tissue fragments, active viruses, active Cells, harmful chemical components, inactive cells, mutation-inducing substances, and some small active virus cells can directly enter the human respiratory system and alveoli. Long-term exposure to mutation-inducing substances can cause human gene mutations. There are two ways to emit smoke from minimally invasive surgery First, the sealing cap of the puncture device will deteriorate due to long-term use, and the smoke will be discharged through the gap of the puncture device; At this time, only the valve of the puncturer can be opened to discharge to the outside, relying on the carbon dioxide gas used for pneumoperitoneum to bring out the smoke, and also discharge a large amount of high-concentration carbon dioxide gas, which will also affect the health of medical staff. There are basically laminar air ventilation systems in operating rooms, but this does not rule out that perioperative medical staff are exposed to surgical smoke. Moreover, there are still many primary hospital operating rooms that do not have laminar air systems. Therefore, in summary, it is necessary to Related innovative design of equipment
