Problems solved by technology

[0005] However, because the nail body of the existing threaded anchor is a whole, the anchor nail body always occupies a place in the bone tunnel, making it difficult for bone tissue to grow into the anchor nail through the anchor nail wall. Therefore, It is not conducive to bone growth and healing. Moreover, during the anchor implantation process, bone debris that is conducive to new bone growth will be completely squeezed out of the anchor, which is also not conducive to bone growth and healing.

Abstract

The invention discloses an anchor nail with a wire. The anchor nail comprises: at least two mutually independent anchor nail sections with preset intervals, and a connecting pin for connecting all theanchor nail sections, wherein the anchor nail section comprises at least one nail body section and one nail head section, and the nail head section is provided with a threading hole for threading a suture; each anchor nail section is fixedly sleeved on outer periphery of the connecting pin, and a through hole used for threading a suture is formed in the connecting pin along an axis of the connecting pin. After the anchor nail with wire is implanted in bone, the connecting pin can be withdrawn from each anchor nail section. After the connecting pin is withdrawn, the anchor nail sections are left in the bone, and since the anchor nail sections are independent from each other and have preset intervals, bone debris and bone tissue are filled in gap between the anchor nail sections, so that the bone tissue grows in the gap, and the bone growth and healing are facilitated.

Description

technical field [0001] The invention relates to the technical field of implantable medical devices, and more specifically, to a threaded anchor. Background technique [0002] Joint soft tissue injury mainly refers to a large category of trauma syndromes caused by direct or indirect violence or long-term chronic strain on tendons, ligaments, and joint capsules. It is a common disease in sports medicine, such as rotator cuff injury, cruciate ligament rupture, Achilles tendon rupture, etc. [0003] For mild soft tissue injuries, it can be relieved quickly after correct treatment by professional doctors; for severe soft tissue injuries, such as tendon avulsion, ligament tear or rupture, etc., surgical treatment is required. [0004] Clinically, for rotator cuff tears, knee collateral ligament injuries, ankle and elbow soft tissue injuries, etc., anchors with wires are usually implanted for repair and treatment. During the operation, a puncher is used to make a bone tunnel on t...
