Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a timely suction piece for dirty surgical fluid. Background Art

[0002] In modern minimally invasive surgery, doctors usually need to operate delicate surgical tools to perform complex surgical steps. During the operation, whether it is cutting, suturing or organ manipulation, blood, body fluids, and flushing fluids may be produced. If these dirty fluids are not removed in time, they will not only affect the doctor's field of vision, increase the difficulty of surgery and the risk of postoperative infection, but also flow onto the sterile sheet and wet the sterile sheet. In the long run, it may cause hypothermia and other phenomena. The traditional dirty fluid cleaning method relies on medical staff to use the drainage tube of the handheld negative pressure drainage system to remove these dirty fluids. This method has several problems: first, additional medical staff are required to be responsible for the cleaning of dirty fluids, which may affect the efficiency of the operation when manpower is tight; second, the handheld drainage tube may not be able to clean all the dirty fluids in time, and the leaked dirty fluids will still overflow to the surroundings, wet the sterile sheet or pollute the surgical environment; finally, the operation of the handheld drainage tube may also interfere with the surgical operation of the main surgeon and affect the progress of the operation.

[0003] Based on this, the applicant considered designing a timely suction device for surgical waste fluids to improve surgical efficiency and safety. Utility Model Content
