Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to a disposable flushing aspirator. Background Art

[0002] Traditional minimally invasive laparoscopic surgery has been gradually replaced by minimally invasive laparoscopic surgery due to its shortcomings such as large trauma area, heavy bleeding and slow postoperative recovery of patients. However, at the same time, minimally invasive laparoscopic surgery requires high operating skills of the surgeon and is highly dependent on the quality and advancement of surgical instruments. Therefore, minimally invasive laparoscopic surgery is currently only well performed in tertiary hospitals in first- and second-tier cities.

[0003] Laparoscopic surgery involves making several incisions of about 1 cm in diameter in the patient's abdominal or thoracic cavity, depending on the location and needs of the surgery. A small light source, laparoscope, and surgical instruments are inserted into the patient's body through a sheath puncture device. The surgeon performs various operations through a monitor connected to the laparoscope.

[0004] During the operation, bleeding is inevitable. Blood and other exudates will seriously interfere with the surgeon's operating field of view. The surgeon will not be able to see the surgical area he wants to see when observing the monitor screen. Therefore, a flushing suction device must be used to clean the surgical area to ensure the smooth progress of the operation.

[0005] When using the existing irrigation and suction device, the user holds the irrigation and suction tube in a vertical position with the arm. During surgery, the wrist is always bent, which is uncomfortable to operate and not conducive to successful surgery. To this end, we provide a disposable irrigation and suction device to solve the above problems. Utility Model Content
