Description

Smoke discharging device for laparoscopic surgery

Technical Field

The invention relates to the technical field of smoke discharging devices, in particular to a smoke discharging device for laparoscopic surgery.

Background

The laparoscopic surgery is a newly developed minimally invasive surgery, and compared with a large incision required in the traditional surgery process, the surgery performed in the abdomen through a small incision is a surgery with small wound surface and pain; when a laparoscopic surgery is performed, a doctor can cut a small hole of 8 mm in the abdomen of a patient, insert a pneumoperitoneum needle, inject a proper amount of carbon dioxide gas, prop open the abdominal cavity to form an operation space, then inject two or three small holes in the other position of the abdomen, extend an eyepiece which is similar to a camera and is illuminated by a laser beam and a surgical instrument, and rotate the eyepiece from all angles, so that the doctor can very clearly see the conditions of five viscera and six entrails in the abdomen from a television screen; electrosurgery, electrocautery and laser are used in surgical procedures, and due to the burning of tissues, surgical smoke is generated in a working space, so that the observation of the lesion area by the operation is influenced.

The mode of traditional getting rid of operation flue gas utilizes pneumoperitoneum needle to bleed air, exhaust the flue gas in the abdominal cavity to the greatest extent, nevertheless also can make the abdominal cavity shrink simultaneously, destroys the operating space of operation, need carry out reinflation through pneumoperitoneum needle to the abdominal cavity just can continue the operation, this kind of mode not only influences going on of operation, greatly increased doctor's operation burden moreover, increase operation time, all be not little burden to patient and doctor, we propose a peritoneoscope operation fog device of discharging fume for this reason and be used for solving above-mentioned problem.
