Description
Technical field
The utility model relates to a kind of band line holdfast, especially a kind of screw-in band line holdfast.
Background technique
Holdfast reconnects soft tissue and bone clinically by suture, and holdfast is embedded to stationary burst tendon in sclerotin
Tissue, to achieve the purpose that tendon-bone healing.Holdfast in the prior art is to have knot to design, i.e., the suture of holdfast end is in outside
It knots and fixes.Publication No. CN104027140A discloses the patent application that a key name is " a kind of three pore area line holdfasts ", in hand
When art, ground anchor body is fixed on bone, each threading hole respectively penetrates suture, and make the both ends of suture be respectively embedded into
In the wire casing that the import of threading hole is connected with the outlet of threading hole, then by the both ends of suture across extensor tendon stop, and
The upper end of extensor tendon stop knots, and extensor tendon stop is made to be fixed on bone surface.But since suture knot is exposed in bone
Head surface is easy to produce friction, causes knot breakage, holdfast to be not fixed firmly, if operative site implantation is undesirable, needs to be inserted into
New holdfast, original band line holdfast cannot be removed, and the above situation easily causes patient uncomfortable and is accompanied by inflammation, leads
Cause healing slow.
Utility model content
The purpose of the utility model is to provide a kind of screw-in band line holdfasts, this kind band line anchor structure is simple, are not necessarily to
