Description

Smoke removing device for laparoscopic surgery

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a laparoscopic surgery smog remove device.

Background

The laparoscopic surgery is a newly developed minimally invasive surgery method and is a necessary trend for the development of future surgery methods. With the rapid advance of industrial manufacturing technology, the fusion of related subjects lays a firm foundation for developing new technology and new method, and doctors perform more and more skillful operations, so that many past open operations are replaced by laparoscopic operations, the operation selection opportunities are greatly increased, and the operation wound is reduced.

The laparoscopic surgery is to make a plurality of small incisions with a diameter of 5 to 12 mm at different parts of the abdomen, insert a camera lens and various special surgical instruments through the small incisions, transmit images of various organs in the abdominal cavity shot by a camera inserted into the abdominal cavity to a display screen, and perform an operation outside the body by a surgeon using various laparoscopic instruments by observing the images. The laparoscopic surgery has small surgical trauma; the recovery of the patient after the operation is fast; the hospitalization time is short; the pain of the patient after the operation is light; the abdominal incision has small scar and is beautiful; the treatment effect is the same as the open abdomen operation, and the like.

However, in laparoscopic surgery, a large amount of smoke, consisting of 95% water or water vapor and 5% particles, is generated during the operation of many instruments (e.g., ultrasonic blade, monopolar or bipolar coagulation, etc.). The smoke contains CO, acrylonitrile, benzene-containing toxic substances and the like, and if the smoke is inhaled by a patient, the smoke can affect the health. And the operation remains in the body of the patient, which has an influence on the health of the patient, for example, the oxygen carrying capacity of red blood cells in the blood of the patient is reduced. In addition, the smoke can cover the laparoscope lens, thereby affecting the surgical field, interrupting the normal surgical operation and prolonging the time of the surgical operation.

In the prior laparoscopic surgery, the switch of the puncture outfit is continuously opened because smoke influences the surgical visual field in the surgical process of an operator, so that the pressure in the abdominal cavity of a patient is changed, and if the pressure in the abdominal cavity of the patient is too low, the space of the abdominal cavity is collapsed, the surgical visual field is influenced, and the surgical operation is influenced; meanwhile, when an operator sucks smog by adopting a laparoscopic aspirator, the suction pressure is overlarge, and the abdominal cavity space is collapsed. In addition, the puncture needs to be occupied for a long time, which is not beneficial to the multidirectional operation of the doctor and the surgical assistant. In addition, the same posture needs to be kept for a long time, which causes the wrist and the finger joint of the operator to be stiff, and greatly increases the workload of the laparoscopic surgery.
