A clamp device for hemostasis or closure of tissue, including clamp housing and at least two clamp arms, wherein clamp arms can be coupled to distal end of control wire of medical instrument to stop bleeding of blood vessel, clamp device can be actuated to open and close clamp arms, which are coupled to each other or can be coupled at proximal ends, clamp arms is provided with guide groove, and guide grooves of clamp arms partially overlap each other, and guide pin attached to clamp housing, and extending in overlapping part of guide grooves and passing therethrough, so that by means of fitting of guide pin and guide grooves, movement of pivot axis is converted into closing movement of clamp arms or opening movement of clamp arms about pivot axis, holding hole being provided on each of clamp arm, holding hole extending from side thereof into guide groove.

Clamp device for hemostasis or closure of tissue and medical instrument for hemostasis or closure of tissue

A medical device for tissue hemostasis or closure that is used by means of an endoscope, the medical device comprising: a handle (); a sheath apparatus () attached to the handle (); a clamping apparatus () comprising a clamping base () and at least or exactly two clamping arms (), the clamping base () specifically being a sleeve and being disposed on a distal end of the sheath apparatus (); a control wire () that extends to pass through the sheath apparatus () and that can move reversibly in a distal direction and a proximal direction; and an actuator (), the actuator () being coupled to a proximal end of the control wire () and being capable of actuating such that the control wire () moves reversibly in the distal direction and the proximal direction.

Medical device for tissue hemostasis or closure

Disclosed is a medical instrument, comprising: a protective sheath device; a clamp device comprising a clamp shell arranged on a distal end of the protective sheath device and at least or just two clamp arms; and a control line extending and passing through the protective sheath device, wherein the clamp shell is directly connected to the protective sheath device by means of at least one connection element and is fixedly attached to the clamp shell, or, a portion thereof is releasably connected to the protective sheath device; and a release mechanism cooperating with each connection element is provided, and when the clamp arms have been closed, the release mechanism can be actuated by means of moving the control line in a proximal end direction so as to release each connection element from the protective sheath device and thus release the clamp shell.
