Example Embodiment

[0035] In order to better understand the object, structure, and function of the present invention, the following detailed description will be described in connection with the accompanying drawings.

[0036] Figure 1 - Figure 9 The structure of the exemplary anchor 10, including anchor body 1, an anchor body 1, an anchor body 1, an anchor body 1, an anchor body 1 including an anchor body 1, anchored body 1 including The threaded connection section 12, and at least one recess 13 is formed on the edge of the outer thread 124 of the threaded connection section 12.

[0037] When using the exemplary anchor 100 in the present invention, a positioning hole for implanting the free knot anchor 100 is first opened in the anchor implantation site on the human bone, and the soft tissue to be fixed by the suture will be fixed. After fixation, the free end of the suture can be passed through the freely tangible anchor 100, and then the exchanuous anchor 100 is implanted into a pre-preserved po...

Abstract

The invention belongs to the technical field of medical instruments, and discloses a knotting-free anchor and an anchor implantation instrument. The knotting-free anchor comprises an anchor body, an axial center hole axially penetrating through the anchor body is formed in the anchor body, and the anchor body comprises a threaded connection section. At least one notch is formed in the edge of theexternal thread of the threaded connection section. The knotting-free anchor has the advantages that sutures can be prevented from being cut off by the knotting-free anchor, and accordingly the fixingeffect of the knotting-free anchor is improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a knot-free anchor and an anchor implantation device. Background technique [0002] Knot-free anchors are implanted devices commonly used in sports medicine orthopedic surgery to fix soft tissue separated from human bone to human bone. [0003] The knot-free anchor in the prior art includes the anchor body and the suture set in the threading hole of the anchor body, and one end of the suture is fixed after the anchor body is embedded in the pre-drilled hole on the human bone. After being fixed, the other end of the suture is connected to the soft tissue and then passed through the threading hole of another knot-free anchor to be further fixed on the human bone. However, this knot-free anchor is in contact with the bone surface through the thread of the outer wall of the anchor body, so that the suture between the outer wall of the anchor body and the bone sur...
