Abstract

The invention discloses a bone tunnel cross pin positioning tool used in the department of orthopaedics and the application thereof. The tool comprises a bone tunnel center hole guider, a cross pin inlet guider, a cross pin inlet preboring needle, a cross pin inlet guiding sleeve, a cross pin inlet grasping stabilizer, an opposite-side bone thickness detection guider, an opposite-side bone thickness detection needle, a bone tunnel center preset confirming needle and a cross pin driver. By the adoption of the tool, perpendicular interlocking and expanding fixation of a cross pin at the center of the interior of a bone tunnel is achieved during ligament reconstruction in the department of orthopaedics.

Description

technical field [0001] The invention belongs to the field of medical auxiliary devices, in particular to an orthopedic bone tunnel transversal nail positioning tool and its application. Background technique [0002] Orthopedic bone tunnel surgery is one of the more complex procedures in orthopedic surgery. Among them, the transversal nail is the most stable and important surgical method for tendon fixation in the bone tunnel. However, in the operation using the transverse nail technology for fixation, the transverse nail often deviates from the tunnel, resulting in the failure of the successful interlocking of the graft and the failure of the operation. In addition, during the operation, it is difficult for the physician to determine in advance whether the transversal nail will penetrate the contralateral cortical bone, which will lead to iatrogenic injury during the operation. In addition, during the operation, metal debris may be left in the operation area in the transve...
