Abstract:
Provided is a medical instrument, comprising a gripper (3), an operating head (2) and a handle (1), wherein the operating head (2) is connected to the gripper (3) and the handle (1). The operating head (2) comprises a housing (10), a triggering force applicator arranged inside the housing (10), a triggering rod (21), a placement cavity (22) arranged on one side of the triggering rod (21), and a clip cartridge assembly (23) arranged inside the placement cavity (22), wherein the triggering rod (21) is connected to the triggering force applicator and the gripper (3) respectively; and an inner cavity (11) in communication with the placement cavity (22) is formed inside the housing (10), and a positioning block (24) is arranged inside the inner cavity (11). The triggering force applicator comprises a push piece (41) and a movable member (42), wherein the push piece (41) is connected to the triggering rod (21) and the movable member (42), and the positioning block (24) is engaged with the push piece (41); and when the positioning block (24) moves forward, the push piece (41) rotates towards the gripper (3) via a first connecting portion to drive the triggering rod (21) to control the gripper (3) to open, otherwise the gripper (3) is closed. The positioning block (24) is engaged with the push piece (41) to drive the triggering rod (21) to move forward or backward so as to control the gripper (3) to open or close, such that the triggering rod (21), the gripper (3) and the clip cartridge assembly (23) can be operated simultaneously without the need to be operated separately and individually, thereby achieving the aims of simplifying a device, rapid triggering and improving efficiency.
