Abstract
The invention provides a clamping instrument and a clamping assembly, which mainly comprises a positioning base, a moving base, at least two clamping arms connected with the moving base, at least two linkage arms respectively connected with each of the clamping arms and the positioning base, and an actuating rod respectively penetrating through the positioning base and the moving base, wherein the positioning base is rotated circumferentially and fixed axially relative to the actuating rod, and the moving base is rotated circumferentially and moves axially relative to the actuating rod; when the movable rod is rotated circumferentially, a distance between the moving base and the positioning base can be changed, and then each of the clamping arms is linked to be rotated around the moving base to be in an unfolded position or a clamped position so as to clamp a preset site of a human tissue. Thus, the rotating amplitude of the clamping arms can be finely adjusted to provide a clamping force with high precision in the present invention.
