Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a cannula-type electric flushing and suction device. Background Technology

[0002] During open or minimally invasive surgery, the surgical wound may produce blood, pus, exudate, etc., resulting in an unclear surgical field. In order to carry out the surgery normally and restore a clear field of vision, it is necessary to use an irrigation suction device connected to saline to irrigate the surgical wound. After irrigation, the blood and water are aspirated out of the body. At present, the suction device connected to a negative pressure generating device is widely used in surgery. It has a suction function and its function is to remove the blood and water produced at the surgical site.

[0003] Existing disposable irrigation and suction devices achieve irrigation and suction through a single stainless steel tube. During suction, blood and water remain inside the stainless steel tube. During irrigation, the blood and water are flushed towards the surgical wound, which can easily cause blockage.

[0004] Therefore, it is of great significance to provide a cannula-type electric flushing suction device to solve the problems existing in the prior art. Utility Model Content
