The coracoclavicular ligament reconstructor comprises a reduction bar, a reduction forceps for clamping the clavicle is arranged at the bottom end of the reduction bar, the top end of the reduction bar is hinged with one end of a C-shaped handle, the reductionbar is provided with a movable block movable along the axial direction of the reduction bar, the movable block is provided with a positioning block through a rotating shaft, and two positioning channels are arranged on the positioning block at intervals; The C-shaped handle is provided with a bar-shaped through hole at one end far from the reset lever, an adjusting screw is fixedly installed at the side of the reset lever, the adjusting screw passes through the bar-shaped through hole of the C-shaped handle, and an adjusting nut is arranged at the end of the adjusting screw. The C-shaped shank is provided with a guide plate through hole facing the direction of the reset lever under the bar-shaped through hole, the guide plate through hole is movably installed with the guide plate, and theC-shaped shank is provided with a guide plate locking bolt on the side of the guide plate through hole, and the guide plate locking bolt extends into the guide plate through hole.
Description
technical field [0001] The invention belongs to the field of medical technology, and in particular relates to a coracoclavicular ligament reconstructor for minimally invasive acromioclavicular joint reduction in orthopedic surgery and a method of use thereof. Background technique [0002] Patients with acromioclavicular joint dislocation usually require acromioclavicular joint reduction, followed by corresponding surgical fixation of the reduced joint, including plate fixation or coracoclavicular ligament (including conical and triangular ligament) reconstruction. In traditional surgery, regardless of the placement of plate fixation or coracoclavicular ligament reconstruction, it is necessary to expose the complete coracoclavicular ligament to establish the coracoclavicular ligament reconstruction channel. , nerve complex, surgery is extremely difficult. Contents of the invention [0003] The purpose of the present invention is to propose a coracoclavicular ligament recon...
