器械密封件
By designing instrument seals with diaphragm seals, winglets, and bellows structures, the problem of unstable instrument sealing during surgery was solved, achieving stable sealing during instrument insertion and withdrawal, and ensuring the stability of pressure within the patient's body and the controllability of the surgery.

AI Technical Summary
In surgical procedures, current technology struggles to maintain a proper seal between surgical instruments, leading to unstable pressure within the patient's body and impacting surgical outcomes.
An instrument seal is designed, comprising a diaphragm seal, multiple vanes, a bellows structure, a disc assembly, and a housing. The seal adapts to the insertion and movement of the instrument by the rotation of the vanes and the flexure of the bellows, ensuring a sealing effect. The seal is also protected against damage and leakage by a slit seal and a retaining structure.
It achieves a stable seal during instrument insertion and withdrawal in surgical procedures, maintains stable pressure within the patient's body, reduces confusion caused by inconsistent friction, and improves the controllability and safety of the surgery.
