Embodiment Construction

[0023] Since elements of the present invention match those shown in the '600 application, their reference numerals are retained. figure 1 There are shown side, top and cross-sectional views of a first exemplary modified elastic osteosynthetic clip 100 according to the present invention, as well as cross-sectional views along the drawn lines A-A, B-B and C-C. The clip 100 includes at least two engaging legs 105a and 105b, and a connecting bridge 110 connecting the connecting legs 105a, 105b to each other so as to form a single clip 100. Engagement legs 105a, 105b extend generally parallel to each other and include respective circular insertion tips 135a, 135b for insertion into bone tissue, and respective overlapping tips 140a, 140b connected to bridge 110. A taper can be made in the engaging legs 105a, 105b by linearly reducing the cross-sectional area along the distance between the overlapping tops 140a, 140b to the corresponding insertion tops 135a, 135b. Such as Figure 1...

Abstract

The present invention is an osteosynthetic clip for healing bone fragments, an improved insertion tool, a method of inserting the improved clip, and a surgical system implementing the improved clip and insertion tool. The clip comprises at least two substantially parallel to each other extending and comprising two engagement legs inserted into the top; a bridge, which is connected to the at least two engagement legs on a portion opposite to the insertion portion, the bridge comprising at least two elongated portions extending oppositely along the sides, the elongated portions extending along a non-linear trajectory to form a non-linear deformation region, such as a groove or a dome; Corresponding helical screw surfaces that extend substantially the entire distance of the screw allow for easy removal of the clip after fusion of the bone tissue fragments. The improved clip can be made of any biocompatible material including shape memory alloys such as Nitinol. The insertion tool has been modified to apply force to the lapped top of stepped or non-stepped clips.

Description

[0001] Related application materials [0002] This application is a continuation of the application published in the 2005 / 0049600 (hereinafter referred to as "Application No. 600"), filed on August 5, 2003, and published on March 3, 2005, entitled "Bone A composite clip and an insertion tool for inserting a bone composite clip into a fragment of bone tissue" has priority, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to an improved osteosynthetic clip having improved structural properties; and an improved device and method for inserting and removing the osteosynthetic clip into fragments of bone tissue and, in addition, to inserting the osteosynthetic clip into An improved insertion tool in bone tissue fragments. Background technique [0004] There are various known parts (e.g., castings and internal parts such as screws, plates, clips, etc.) that heal bone parts and / or fragments by holding them tog...
