Description

A liquid suction device for inner lens

Technical Field

The utility model relates to the technical field of endoscope devices, in particular to a liquid aspiration device for an endoscope lens.

Background technique

Endoscopic surgery is a surgery performed by introducing an endoscope into the body cavity through the mouth or rectum. During the operation, due to the need for cutting or flushing, a large amount of blood and water often accumulate in the body cavity, blurring the surgeon's vision and hindering the progress of the operation. Therefore, when a large amount of blood and water appear, it is necessary to open the suction channel installed on the endoscope to suck the blood and water out of the body. However, during the operation, some surgical instruments often need to enter the body cavity through the suction channel, so the water absorption area of the suction channel is not enough to effectively absorb the blood and water.

Chinese patent CN213098388U discloses "a laparoscopic surgery smoke exhaust device" which uses a hose with threads and a one-way valve to exhaust smoke during laparoscopic surgery. It also has a silencer cap and a dust cap, and one end of the thread is connected to a poking card. Due to different targeting, the technical solution of CN213098388U is suitable for exhausting smoke but cannot effectively exhaust blood and water. The existing suction channel on the endoscope is blocked because it needs to be used as a channel for some surgical instruments. It is not enough to drain the blood and water. Therefore, it is necessary to further install a device that can drain the blood and water.

Summary of the invention

In order to further drain the blood and water and play a role in supplementing the existing suction potential channel, the utility model provides a liquid suction device for the inner lens, which can effectively drain the blood and water around the inner lens.
