Problems solved by technology

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 surface is squeezed to fix the suture. When the edge of the thread is sharp, the suture may be cut off, causing the suture to lose its fixation effect; when the edge of the thread is not sharp enough, the stability of the anchor in the pre-drilled hole on the human bone is not good, so the fixation effect will be affected

Embodiment Construction

[0035] In order to better understand the purpose, structure and function of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0036] Figure 1-Figure 9 The structure of the knot-free anchor 100 according to the embodiment of the present invention is shown, which includes an anchor body 1, and an axial center hole 11 axially penetrating the anchor body 1 is formed on the anchor body 1, and the anchor body 1 includes In the threaded connection section 12 , at least one notch 13 is formed on the edge of the external thread 124 of the threaded connection section 12 .

[0037] When the knot-free anchor 100 of the embodiment of the present invention is in use, a positioning hole for implanting the knot-free anchor 100 is opened at the anchor implantation site on the human bone, and the soft tissue to be fixed is fixed with sutures. After fixing, the free end of the suture can be passed through the...

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...
