Abstract: A stitching anchor nail includes an anchor body in a shape of straight tube, a non-circular blade jack formed in and through an axis portion of the anchor body along an axis direction thereof, a thread-in structure at a rear-end part of the anchor body, and a spiral tooth structure formed on a side surface of the anchor body and extending from a rear-end part toward a front end of the anchor body along a spiral direction. The spiral tooth structure is formed with a tooth-in entrance at a front end thereof and has a cross section in a shape of a trapezoid having an included angle ranging from 45 to 55 degree between two side edges of the trapezoid and has a tooth top in a width ranging from 0.4 to 0.7 mm.

Abstract: This invention is related to an anchor implantation system capable of being fixed on a bone and including an anchor and an awl. The anchor comprises an inner side, an outer side and a perforation in connection therewith, and the anchor further includes an accommodating portion and a thread portion. The accommodating portion and the thread portion are disposed at the inner side and the outer side of the anchor, respectively. One end of the awl penetrates the accommodating portion and protrudes from the perforation, and the shape of the cross section of the awl is non-circular. The awl is rotatable to drive the anchor, so that the anchor is screwed into the bone with the thread portion. The present disclosure provides a rotating awl with a non-circular shape in cross section to enlarge a pilot hole when drilling the bone, so that the anchor can be screwed into the bone while drilling.
