The plane-shaped pressing plate 1 and the attaching surfaces of bones and ligaments are both planes, and the arc-shaped pressing plate 1 and the attaching surfaces of the bones and the ligaments have partial arc surfaces (the middle part or two ends) or integral arc surfaces; the middle part of the pressing plate 1 is an arc surface as shown in figure 5, the two ends of the pressing plate 1 are arc surfaces as shown in figure 4, and the whole pressing plate 1 is arc-shaped as shown in figure 6. This application sets up curved clamp plate 1 and makes the laminating degree of door type nail and skeleton and ligament higher, also more can adapt to different patients, reduces the postoperative pine and takes off the probability.
One or two columns 2 are arranged on the pressing plate 1. The column body 2 is in a pawl-shaped or gun head-shaped structure. The column body 2 comprises a head 202 and a column body 201. The cylinder 2 with the inverted tooth-like structure forms inverted teeth 203 on the outer wall of the cylinder 201, and the inner wall of the cylinder 201 is smooth and is positioned on the same plane with the inner wall of the head 202 (as shown in fig. 7). The head 202 of the body 2, which is in the form of a lance tip, is triangular pyramid shaped, and the base area of the head 202 is greater than the upper surface area of the shaft 201 (as shown in fig. 8). This application is 2 designs the cylinder and is pawl form or rifle head column structure, fixes with tissue around for better, prevents that door type nail from coming out from the tissue pine.
One or more screw holes 3 are formed on the pressing plate 1. The screw hole 3 is divided into two forms of a threaded (matched with a locking screw) and a non-threaded (matched with a cortical bone screw) according to different selected screws, the screw hole 3 with threads is shown in fig. 13, and the screw hole 3 without threads is shown in fig. 14; according to the different positions of the screws screwed into the pressure plate 1, screw holes 3 can be processed at the diagonal part, the middle part or the end part of the pressure plate 1; this application processes out screw hole 3 on clamp plate 1 to make door type nail be aided with cortex bone screw or locking screw and strengthen fixedly, thereby improved the fixed strength of door type nail, reduced the risk that the postoperative pine takes off.
The middle of the bottom surface of the pressure plate 1 is provided with sawteeth 4 or spikes 5. The sawteeth 4 and the spikes 5 are divided into a long type and a short type, wherein the long type sawteeth 4 are shown in figure 9, the short type sawteeth 4 are shown in figure 10, the long type spikes 5 are shown in figure 11, and the short type spikes 5 are shown in figure 12. This application sets up sawtooth 4 or spine 5 of different lengths through the bottom surface at clamp plate 1, can strengthen the adhesive force to the ligament after squeezing into on the one hand, and on the other hand also can select different structures according to different patients' different situations to increase the firmness of this application door type nail.
