Stitching Anchor Nail and System As Well As Implantation Method Thereof

#This application claims priority to Taiwan Application Serial Number 109142723, filed Dec. 4, 2020, which is herein incorporated by reference.

#This invention relates to a medical device, and in particular to a stitching anchor nail being implanted into a bone in a surgery and a system thereof as well as an implantation method thereof.

#An anchor nail is a surgical instrument applied to stitch soft tissues such as ligaments. In such a stitching surgery, the anchor nail is used to secure one end of a stitching thread to a bone. After the soft tissue is stitched with the thread, another anchor nail is used to tighten and secure the other end of the thread. In order to implant the anchor nail into the bone, the current practice uses a kind of instrument to chisel out a guiding hole in the bone, and then puts a driving rod into the anchor nail and turns the driving rod so as to drive the anchor nail into the bone along the guiding hole. However, there are some problems with the existing practices mentioned above.

#The invention will be described with reference to the following drawings, wherein like numerals refer to like elements, and wherein:

#FIG. 1 is an explosive diagram of the stitching anchor nail according to a preferred embodiment of the present invention;

#FIG. 2 is a three-dimensional diagram of the stitching anchor nail according to the preferred embodiment of the present invention;

#In the following, with reference to accompanying drawings of embodiments of this invention, technical features and practical effect of this invention will be clearly and completely described as below. Apparently, the embodiments of the invention described below only are a part of embodiments of the invention, but not all embodiments. Based on the described embodiments of the invention, all other embodiments obtained by ordinary skill in the art without creative effort belong to the scope of protection of the invention.

#In a preferred embodiment shown in FIG. 1 to FIG. 5, the present invention provides a stitching anchor system, including a stitching anchor nail 10 and a driving blade 20, wherein the stitching anchor nail 10 comprises an anchor body 11 that is in a shape of straight tube having a front end and a rear end.

#The stitching anchor nail 10 further comprises a non-circular blade jack 12 formed in and penetrating through an axis portion of the anchor body 11 along an axis direction of the anchor body 11. In this preferred embodiment, the blade jack 12 is in a shape of a square hole having a center on the axis of the anchor body 11. The blade jack 12 is formed with four blade corners 121 contained in a same hypothetic circular track A at the front end of the anchor body 11. The circular track A also have a center on the axis of the anchor body 11.
