In order to better realize the utility model, the anchor rod, the connector and the anchor head are made of titanium alloy materials.

The beneficial effects of the utility model are as follows: according to the full-thread taper locking threaded anchor, the anchor rod, the connector, the anchor head, the threading hole, the first external thread, the second external thread and the like are matched to form a full-thread design in the length direction, so that a product can be well matched with a bone when implanted into the bone, and falling is prevented.

The conical design reduces resistance in the implantation process, shortens operation time, and reduces injury to patients.

The anchor rod is provided with the second external thread and the third external thread to form a high-low double-thread structure, so that larger anti-extraction force is provided, and the combined implant can be better fixed on the surface of a bone.

The anchor head comprises a tapping cone arranged at the lower end of the anchor rod, and a chip removing groove is formed in the lateral part of the tapping cone, so that the screw-in of the anchor and the discharge of bone fragments are facilitated.

Detailed Description

Embodiments of the technical scheme of the present utility model will be described in detail below with reference to the accompanying drawings. The following examples are only for more clearly illustrating the technical aspects of the present utility model, and thus are merely examples, and are not intended to limit the scope of the present utility model.

It is noted that unless otherwise indicated, technical or scientific terms used herein should be given the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

Examples:

as shown in fig. 1 to 3, the full-thread taper locking strip line anchor comprises an anchor rod 1, wherein a connector 2 is arranged at the upper end of the anchor rod 1, and an anchor head 3 is arranged at the lower end of the anchor rod 1; a threading hole 5 which penetrates horizontally is arranged on the connector 2, and a first external thread 8 is arranged on the connector 2; a second external thread 6 is provided on the shank 1.
