Occlusion device for medical or surgical instrument valve, has cylindrical part deforming in torsion to create striction zone, two obturation organs pressing against each other to close passage when part is deformed

摘要

The device has a hollow cylindrical part (1) deformable in torsion along an axial direction to create a striction zone. Two obturation organs (2a, 2b) form an integral part of an inner wall of the cylindrical part by forming a passage. The organs are arranged to press against each other to close the passage when the cylindrical part is deformed in torsion. An Independent claim is also included for a valve for medical or surgical instrument.
