Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of shell suction heads, in particular to an adjustable surgical suction head. Background Art
[0002] During surgical operations, an aspirator is often needed to absorb smoke generated by electrosurgery or ultrasonic scalpels when cutting tissues, or to absorb liquid or blood to keep the surgical field clear. Traditional aspirators are mainly connected to a negative pressure pump for suction, and the aspirator includes a suction head. The traditional suction head has a simple structure and is directly through-hole. When the suction head is not in use, the liquid that has been sucked into the suction head is easy to flow back from the hose. In addition, there is no adjustment structure on the traditional suction head. When the suction head is in use, it is easy to cause secondary injury to the patient's wound due to the large suction force. Utility Model Content
