Embodiment 1

[0051] This embodiment provides an anchor with a wire, including: an anchor body with a wire 1; a threaded part 2, the threaded part 2 is arranged on the outside of the anchor with a wire body 1; a threading structure is arranged on the anchor with a wire The wire anchor body 1; the force-bearing structure is set on the wire anchor body 1; the threaded part 2 is a threaded structure arranged in height.

[0052] The above-mentioned technical solution is the core technical solution of the threaded anchor of the present invention. By setting the thread structure arranged at high and low levels, the above-mentioned thread structure can resist pulling out better than the general thread structure, and when screwed into the bone, it can reduce the Screwing in the torque is not only convenient for the doctor to operate, but also reduces the pain of the patient. At the same time, the effect of fixing the bone is good, so that the anchor with the wire is not easy to loosen, and the patie...

Embodiment 2

[0057] This embodiment provides a handle used in conjunction with a wire anchor, including: a handle 6; a hollow body 7, one end of the hollow body 7 is connected to the handle 6, and the other end forms a Fitting inner cylinder hole 8 .

[0058] The above technical solution is the core technical solution of the handle of the present invention. By setting the handle, it is convenient to apply a rotating force to the hollow body, and then to apply a screwing force to the anchor with wire; It is more labor-saving when entering.

[0059] Specifically, such as Figure 3-5 As shown, the handle 6 is used to rotate the hollow body 7, and its shape is not limited. Preferably, the handle 6 is ergonomically designed to provide comfort and ease of use for doctors to hold. In order to reduce the weight of the handle 6, when making the handle 6, adopt as many empty groove interval designs as possible, that is, while conforming to the ergonomic design, reduce the doctor's holding strength...

Abstract

The invention relates to a suture anchor which comprises a suture anchor body, a thread part, a threading structure and a stress structure, wherein the thread part is arranged at the exterior of the suture anchor body; the threading structure is arranged on the suture anchor body; the stress structure is arranged on the suture anchor body; the thread part is of a thread structure distributed in a high-low manner. By virtue of the thread structure distributed in a high-low manner, the thread structure has stronger anti-pull capacity than a common thread structure; during a process of screwing into a bone, the screwing torque can be reduced, so that not only can medical operation be facilitated, but also pains of patients are reduced; furthermore, the effect of the bone fixation is good, the suture anchor is difficult to loose, secondary injury of the patients is avoided. The invention also relates to a handle matched with the suture anchor, and the handle is simple to use and convenient to install and dismount.

Description

technical field [0001] The invention relates to the technical field of surgical fixation nails for suturing wounds, in particular to a threaded anchor and a handle thereof. Background technique [0002] When the soft tissue is torn away from the bone and needs to be repaired, the surgeon is usually required to repair the separated soft tissue with sutures attached to the bone with threaded anchors. Among them, the parts where soft tissues are easily torn from bones are generally in the shoulder joints, knee joints, and hip joints. In use, the suture anchor is implanted into the bone, sutures are threaded through the soft tissue to be reattached, and the sutures are then secured to the anchor with the appropriate tension to achieve tendon-bone healing. [0003] The threaded anchors in the prior art generally include an anchor body and threads are provided on the anchor body, and at the same time, a threading structure and a force-bearing structure are provided on the anchor ...
