Adjustable tendon graft cutter

Abstract

The invention discloses an adjustable tendon graft cutter, and belongs to the field of medical instruments. The adjustable tendon graft cutter comprises a handle, the right side of the handle is fixedly connected with a telescopic cavity, the top end of the telescopic cavity is fixedly connected with a cutter clamping upper groove, the interior of the telescopic cavity is slidably connected with a telescopic plate, and the lower surface of the telescopic plate is fixedly connected with a telescopic column. The bottom end of the telescopic column is fixedly connected with a cutter clamping lower groove, and the interior of the cutter clamping upper groove and the interior of the cutter clamping lower groove are both connected with blades in a clamped mode. The rotary column and the threaded ring at the bottom end of the rotary column are driven to slide up and down in the threaded groove by rotating the rotary knob on the right side of the handle, so that the positions of the sliding plate and the telescopic plate connected with the sliding plate are accurately controlled, the distance between the upper clamping knife groove and the lower clamping knife groove is accurately adjusted, and the requirements of different operations for cutting depth and width are met. Meanwhile, the ranging rod on the front surface of the lower cutter clamping groove is matched with the buckle on the front surface of the telescopic cavity, and the ranging rod can synchronously slide along with the change of the distance between the blades.
