Problems solved by technology
[0006] The object of the present invention is to provide a trumpet-shaped implant and its implantation method, to solve the stress concentration on one side of the tunnel mouth caused by the "wiper effect" of the bone tunnel mouth after ligament reconstruction in the prior art, and the stress on the opposite side. Technical problems of bone resorption caused by disappearance, expansion of tunnel mouth and stress concentration of grafted ligaments, wear and fracture

The invention discloses a horn-like implant and an implanting method thereof, relates to the technical field of ligament reconstruction, and aims to solve the technical problem of stress concentrationon one side of a tunnel entrance due to windshield wiper effect at bone tunnel entrance after ligament reconstruction operation and the technical problems of bone resorption, tunnel entrance expansion as well as stress concentration, abrasion and fracturing of a transplanted ligament caused by opposite side stress disappearance in the prior art. The horn-like implant comprises a horn surface structure and a base column communicated with the reducing end of the horn surface structure, wherein the outer side wall of the base column is provided with a side wing; the horn surface structure is used for covering the bone tunnel; the base column extends into the bone tunnel, and is fixed in the bone tunnel by the side wing; the horn surface structure is made of a single curved surface or a plurality of curved surfaces in a connection manner; the plurality of curved surfaces are tangent to one another to serve as a transition surface at the bone tunnel entrance.
Description
technical field [0001] The invention relates to the technical field of ligament reconstruction, in particular to a trumpet-shaped implant and an implantation method thereof. Background technique [0002] Ligament injuries will greatly affect the normal life of patients. At present, there are many types of ligament injuries seen clinically, including knee ligament injuries, shoulder ligament injuries, elbow ligament injuries, and ankle ligament injuries. Among them, as an important stabilizing device of the knee joint, the anterior cruciate ligament (ACL) is one of the most vulnerable ligaments. ACL injury will directly lead to the instability of the knee joint, greatly reducing the quality of life of the patient, and long-term damage to the meniscus, etc. Secondary damage to other appendages of the knee eventually leads to arthritis. [0003] At present, the clinical treatment of ligament injury is mainly ligament reconstruction, which replaces the original ligament with au...
