Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and specifically relates to a shadowless aspirator. Background Art

[0002] As an important medical device in the medical field, the aspirator is mainly used to aspirate foreign matter, secretions, blood, etc. in or on the body during surgery to keep the surgical area clean or for treatment. With the continuous advancement of medical technology and changes in social needs, the current aspirator usually adopts a handheld suction head design and is connected to the main body of the aspirator. Common aspiration methods of the aspirator main body include vacuum aspiration, which generates negative pressure inside the aspirator main body, thereby generating attraction to suck the target object into the container inside the main body through the suction head.

[0003] During the actual suction operation, the suction head is affected by its own structure. When it is extended into a narrow area, it is easily affected by insufficient light, resulting in an inability to determine whether the liquid is sucked cleanly, which greatly increases the risk of infection during surgery. Therefore, there is a problem of not being able to provide effective lighting during suction. Utility Model Content
