[0031] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0032] In combination with the drawings Figures 1-11 A line pressing and locking plate for joint fixation, comprising:

[0033] A bottom plate 100, the bottom plate 100 is symmetrically provided with a locking nail hole 101 at both ends, the bottom plate 100 is provided with a groove 102 in the middle, the groove 102 in the middle of the bottom plate 100 is provided with a first screw hole 104 penetrating through the bottom plate 100, the bottom plate 100 is provided with a rice-shaped line groove 103 in the middle, the rice-shaped line groove 103 passes through from the groove 102;

[0034] Further comprising a line pressing plate 200, the line pressing plate 200 is arranged in the groove 102, the line pressing plate 200 is provided with a second screw hole 201, the second screw hole 201 is provided with a line locking device screw 202, the line pressing plate 200 is connected and matched with the first screw hole 104 through the line locking device screw 202;

[0035] The bottom of the line locking device screw 202 is provided with a notch 203.

[0036] In this case, it is a double-hole line pressing plate, the groove 102 and the line pressing plate 200 are the same shape, both of which are an oval in the middle, and the two ends of the oval are symmetrically provided with a circle;

[0037] Two first screw holes 104 are symmetrically provided in the groove 102, respectively set on the circles at both ends of the ellipse. The cross-shaped groove 103 passes through the middle of the groove 102 and extends out from both ends of the bottom plate 100.

[0038] The second screw hole 201 is symmetrically arranged at both ends of the pressure plate 200. The two second screw holes 201 are respectively set on the circles at both ends of the ellipse, that is, each pressure plate is individually fixed by two wire locking screws 202. This design is similar to butterfly wire pressing. Each wire locking screw 202 presses the line on one side, which is suitable for situations that require high flexibility and line splitting. It has strong line splitting ability and can adjust the line position as needed.

[0039] In this case, the groove 102 and the wire plate 200 have the same shape, both being a circle in the middle with symmetrically arranged ellipses at both ends.

[0040] The first screw hole 104 is located in the middle of the groove 102 and on the circle in the middle of the two ellipses. Two cross-shaped grooves 103 are symmetrically provided on the base plate 100, respectively located in the elliptical parts of the two grooves 102. The two cross-shaped grooves 103 pass through the grooves 102 and extend out from both ends of the base plate 100.

[0041] The second screw hole 201 is provided in the middle of the pressure plate 200, and is set on the circle in the middle of the two ellipses. A locking screw 202 simultaneously presses the two elliptical plates of the pressure plate. This design increases the firmness of the pressure plate because the two plates share the pressure of a screw, making the line more stable and less prone to movement.

[0042] The base plate 100 is made of titanium alloy.

[0043] The pressure plate 200 is made of titanium alloy.

[0044] In specific implementation, this utility model

[0045] Example 1, as Figures 1-5 As shown, this is a double-hole wire clamping plate, where each wire clamping plate 100 is individually fixed by two wire locking screws 202. This design is similar to butterfly wire clamping, with each wire locking screw 202 clamping the wire on one side. It is suitable for situations requiring high flexibility and wire separation. It has strong wire separation capabilities and can adjust the wire position as needed.

[0046] In use, the wire is placed in the herringbone wire slot 103, then the wire is inserted into the second screw hole 201 on the wire pressing plate 200 through the wire locker screw 202, then the wire is passed through the notch 203 at the bottom of the wire locker screw 202 and adjusted to the right position, then the wire locker screw 202 is screwed into the first screw hole 104, so that the wire pressing plate 200 and the wire locker screw 202 press the wire and fix it on the base plate 100; then the base plate 100 is placed at the joint to be fixed, etc., and the base plate 100 is fixed on the bone through the locking nail holes 102 at both ends with screws; in this way, the entire device forms a stable fixing structure, which can effectively prevent the joint from further dislocation, and the operation is relatively simple and the fixation is relatively firm.

[0047] When the shoulder and elbow joints are dislocated, the wire can be placed in the herringbone wire slot 103 of the base plate 100, and then fixed by the above-mentioned method.

[0048] When the ulnar diastasis occurs, the locking plate is placed at the diastasis to fix and prevent further dislocation; specifically, the locking plate is designed to allow the wire to pass through the herringbone wire slot 103 in the center, and the wire is fixed by the compression mechanism of the wire locker screw 202 to prevent the wire from retracting or loosening; the compression mechanism is similar to a key or butterfly-shaped structure, which can uniformly compress the wire in the wire slot on both sides, so that the wire is flatly attached to the titanium plate.

[0049] Example two, as shown in Figures 6-10 ; it is a single-hole wire pressing plate, that is, a wire locker screw 202 simultaneously compresses two oval plates of the wire pressing plate 200, which increases the firmness of the wire pressing, because the two plates jointly bear the pressure of a wire locker screw 202, so that the wire is more stable and not easy to move, however, the wire separation ability of this case is relatively weak, because the two plates are fixed as a whole, which may not be as firm as the double-wire plate in some positions;

[0050] In use, the wire is placed in the herringbone wire slot 103, then the wire is inserted into the second screw hole 201 on the wire pressing plate 200 through the wire locker screw 202, then the wire is passed through the notch 203 at the bottom of the wire locker screw 202 and adjusted to the right position, then the wire locker screw 202 is screwed into the first screw hole 104, so that the wire pressing plate 200 and the wire locker screw 202 press the wire and fix it on the base plate 100; then the base plate 100 is placed at the joint to be fixed, etc., and the base plate 100 is fixed on the bone through the locking nail holes 102 at both ends with screws; in this way, the entire device forms a stable fixing structure, which can effectively prevent the joint from further dislocation, and the operation is relatively simple and the fixation is relatively firm.

[0051] In the shoulder and elbow dislocation, the wire can be placed in the 100-meter cross-shaped slot 103 of the base plate, and then fixed by the above-mentioned way.

[0052] When the ulnar diastasis occurs, the locking plate is placed at the diastasis to fix and prevent dislocation; specifically, the design of the locking plate allows us to pass the wire through the 100-meter cross-shaped slot 103 in the center, and fix the wire by the compression mechanism of the locking screw 202, to prevent the wire from retracting or loosening; the compression mechanism is similar to a key or butterfly-shaped structure, which can uniformly compress the wire in the slot on both sides, so that it is flat on the titanium plate.

[0053] Compared with the double-hole wire compression plate, the single-hole wire compression plate may be slightly inferior in fastening, because the double-hole design usually provides more stable fixation, and the wire needs to pass through the slot 203 at the bottom of the two locking screws 202 to fix it; however, the single-hole wire compression plate has its unique advantages, because the wire is directly passed through the 100-meter cross-shaped slot 103 beside the first screw hole 104, once the wire loosens, it can be more easily adjusted or re-passed from the side, which makes the single-hole wire compression plate more convenient in occasions that require flexible adjustment or quick replacement of wire; in addition, the single-hole design also allows the wire to rotate or reverse when needed, increasing the flexibility of use; in actual operation, it can be selected as needed.
