Description

Suction device capable of being loaded on ultrasonic knife

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a suction device which can be arranged on an ultrasonic knife.

Background

At present, laparoscopic minimally invasive therapy is the first choice in clinical surgery, and is more and more favored by surgeons because of the characteristics of small wound and quick recovery. In the minimally invasive surgery, the ultrasonic knife utilizes heat energy to cut and separate tissues, smoke is generated, the visual field of a laparoscope lens is easily influenced, the dissecting position in a deep place and a small space is more obvious, the operation of a surgeon is easily influenced, and the surgery time is increased. There is no good solution clinically, and when the abdominal cavity is heavily smoky, the laparoscopic lens is usually treated or warmed by temporary surgery, deflation from the operation hole or suction with a suction apparatus from the operation hole. Such methods are time consuming and tend to increase risk when bleeding from the tissue or other conditions arise.
