Description

Anchor nail implantation device Technical Field The present disclosure relates to medical devices, and more particularly, to an anchor implanter. Background The band wire anchor is a very small implant commonly used in sports medical operations and can be used for fixing a suture in a bone, and is widely applied to clinical treatment of tendon, ligament and other soft tissue injuries at present. The affected parts treated by the band-line anchor have different recovery periods due to different physique of patients, and especially some old people with poor bone quality may have longer healing periods. Disclosure of utility model The present disclosure provides an anchor implanter capable of accelerating early healing of affected parts to improve use reliability of the anchor implanter. Aiming at the purposes, the present disclosure provides the following technical scheme: In one aspect of the present disclosure, an anchor implanter is provided that includes a stripline anchor including a trabecular bone-like porous structure, a head portion provided with an anchor blade, and a tail portion provided with a drive mount, and a drive structure detachably connected to the drive mount and capable of driving the stripline anchor into a predetermined bone location. In an exemplary embodiment of the present disclosure, the porosity of the trabecular bone-like porous structure is 50% -70%, and the pore size range is 300 μm-700 μm. Further, the belt line anchor is a bioabsorbable metal article. Optionally, the band wire anchor is made of zinc alloy or magnesium alloy, and/or the trabecular bone-like porous structure is arranged at the outer peripheral side of the band wire anchor and extends centrally from the outer peripheral side, and/or the outer peripheral side of the band wire anchor is provided with threads. In another exemplary embodiment of the present disclosure, the band wire anchor has two circumferential Xiang Chuanxian holes penetrating opposite sides of the band wire anchor, and the two circumferential threading holes are disposed at intervals along an extension direction of the band wire anchor.
