The adjusting nut (20) drives the sheath connector (13) to move axially. The sheath connector (13) presses the elastic sealing member (12) within the moving path to enable the elastic sealing member to switch between the first state and the second state. In the first state, the delivery channel is in a communication state, and in the second state, the delivery channel is in a closed state. The hemostasis valve (10) does not need to be disassembled from the delivery device (100) during surgery."
