With the change of treatment concepts, the progress of surgical equipment and the improvement of surgical technology, many diseases which can be solved by open surgery in the past can be solved by minimally invasive surgery. In the prior bone joint surgery, the joint needs to be completely opened, and then the focus is treated. In contrast, arthroscopic surgery generally requires only two small incisions, one for placement into the arthroscope, and the orthopaedic surgeon performs viewing feedback based on video images returned by the endoscope, and the other for placement into surgical instruments used in the joint cavity, such as a gyratory sharpener, a occluder, etc. Therefore, the method has been widely used clinically due to the small surgical trauma, faster recovery, fewer scars and smaller incisions.
In arthroscopic surgery, lavage fluid such as normal saline is generally used for joint expansion to form a surgery space, so that the operation of medical staff is facilitated, and meanwhile soft tissue contusion is prevented. During the operation, due to the need of replacing the insertion device and the frequent rotation movement of the device, incision expansion is easily caused, and the surgical devices have different diameters, so that the condition that lavage fluid flows back from the incision in the joint and even is sprayed out is inevitably caused (figure 1). With the advancement of surgery, the towel and the operating table can be soaked, the operation of the operator is affected, and the lavage liquid sprayed out of the towel can splash the surgical gown or directly contact eyes, skin and the like, so that the exposure risk of the operator is greatly increased.

The other patent is improved on the basis of the method (publication number: CN 213429967U), the equipment is pulled out to form a closed space, but the device is only suitable for the use of columnar surgical instruments due to the long tubular rigid structure, so that the use of other surgical instruments (such as vascular clamps and tissue shears) is limited, the flexible operation of the operation is not facilitated, and the infection exposure risk of a patient is increased due to repeated disassembly. Therefore, there is a further need for an anti-reflux water-leakage arthroscopic surgical kit suitable for a variety of available instruments that can substantially reduce the operator's exposure and difficulty of operation while maintaining surgical efficiency.
