Background
Myotendinous metastasis is a common procedure in orthopedic orthopedics. In tendon transfer surgery, the tendon is usually fixed to the bone by an anchor. Because the price of the anchor nail is high, the operation cost is high, and the tendon and the bone are not easy to be fused together because the pressing force and the pressing area between the tendon and the bone are small. In addition, the metal anchor is a foreign body, and the metal anchor is often in trouble in safety inspection when carrying the metal foreign body in the body. In order to reduce the operation cost and improve the fusion between the tendon and the bone, the applicant fixes the tendon and the bone by suturing, and the quality of the fusion of the tendon and the bone of a patient is high through multiple clinical practices. However, suturing requires drilling a plurality of blind holes in the bone, each blind hole communicating with at least one other blind hole to facilitate the introduction and removal of the suture. Clinical practice has shown that it is extremely difficult for ordinary medical personnel to drill blind holes in bones by a bare-handed electric drill and ensure communication between the blind holes, and waste holes are often made in bones.
