[0028] Embodiment one: please refer to Figures 1 to 7 :
[0029] The utility model proposes a kind of whole lock nailer for skeleton reset, it include: main locking plate 1;
[0030] The left and right sides of main locking plate 1 are slidably installed with an auxiliary locking plate 2, and the main locking plate 1 and the auxiliary locking plate 2 can be fixed to the fracture site in cooperation;Four locking holes 3 are provided on the main locking plate 1, and one locking hole 3 is provided on the auxiliary locking plate 2, and when installing, bone nail 4 can be inserted into the locking hole 3 and nailed into the skeleton;Bone nail 4 is adaptedly installed in the locking hole 3, and when installing, bone nail 4 can be inserted into the locking hole 3 and nailed into the skeleton, so that the main locking plate 1 and the auxiliary locking plate 2 can be fixed on the surface of the skeleton;A locking block 5 is rotatably installed on the top inner side of bone nail 4, and the protruding block on the outer side of locking block 5 will be embedded in the vertical groove of L-shaped groove on the inner wall of locking hole 3 during the process of nailing bone nail 4 into the skeleton, and after nailing bone nail 4 into the skeleton, cross screwdriver can be inserted into the cross-shaped groove on the top of adjusting head 6 and driven to rotate clockwise by 90 °, so that locking block 5 can drive the protruding block on its outer side to rotate synchronously, at this time, the protruding block on the outer side of locking block 5 will be clamped in the horizontal groove of L-shaped groove on the inner wall of locking hole 3, so that the displacement of bone nail 4 in locking hole 3 can be limited;The top of locking block 5 is fixed with an adjusting head 6, and after nailing bone nail 4 into the skeleton, cross screwdriver can be inserted into the cross-shaped groove on the top of adjusting head 6 and driven to rotate clockwise by 90 °, so that locking block 5 can drive the protruding block on its outer side to rotate synchronously.
[0031] In the embodiments of the present disclosure, as Figures 5-7As shown, the outer side of the locking block 5 is provided with two protruding blocks, and the inner wall of the locking hole 3 is provided with two L-shaped grooves, and the protruding blocks on the outer side of the locking block 5 can slide up and down and rotate in the L-shaped grooves on the inner wall of the locking hole 3. During the process of driving the bone pin 4 into the bone, the protruding blocks on the outer side of the locking block 5 will be embedded in the vertical grooves of the L-shaped grooves on the inner wall of the locking hole 3. After the bone pin 4 is driven into the bone, the cross screwdriver can be inserted into the cross-shaped groove at the top of the adjusting head 6 and rotated clockwise by 90°, so that the locking block 5 can drive the protruding blocks on the outer side thereof to rotate synchronously. At this time, the protruding blocks on the outer side of the locking block 5 will be clamped in the horizontal grooves of the L-shaped grooves on the inner wall of the locking hole 3, so as to limit the displacement of the bone pin 4 in the locking hole 3.
[0032] In the embodiments of the present disclosure, as shown in Figure 4 As shown, the bottom of the main locking plate 1 is provided with a rectangular groove on the left and right sides, and the thickness of the rectangular groove is equal to the thickness of the auxiliary locking plate 2. After the device is produced, the auxiliary locking plate 2 can be rotated horizontally and pushed to the innermost side of the rectangular groove at the bottom of the main locking plate 1, so that the whole bone pin locking device can be shortened, and packaging and storage are facilitated.
[0033] In the embodiments of the present disclosure, as shown in Figure 5 and Figure 6 As shown, the top of the bone pin 4 is provided with a cylindrical groove in the middle, and the adjusting head 6 is located in the cylindrical groove in the middle of the top of the bone pin 4, and the top of the adjusting head 6 is provided with a cross-shaped groove. After the bone pin 4 is driven into the bone, the cross screwdriver can be inserted into the cross-shaped groove at the top of the adjusting head 6 and rotated clockwise by 90°, so that the locking block 5 can drive the protruding blocks on the outer side thereof to rotate synchronously.
[0034] In the embodiments of the present disclosure, as shown in Figures 1-4 As shown, the front and rear sides of the auxiliary locking plate 2 are also provided with a circular rod. The circular rods on the front and rear sides of the auxiliary locking plate 2 can slide left and right and rotate in the guide grooves on the front and rear sides of the rectangular groove at the bottom of the main locking plate 1. If the surface of the bone to be fixed is bent, the auxiliary locking plate 2 can be pulled outward to the outermost side first, and then the auxiliary locking plate 2 can be rotated and adjusted under the support of the circular rods on the front and rear sides thereof, so that the main locking plate 1 and the auxiliary locking plate 2 can adapt to the bone surface with different radii as a whole.
[0035] In the embodiments of the present disclosure, as shown in Figure 4 As shown, the inner side of the rectangular groove at the bottom of the main locking plate 1 is provided with two protruding plates, and when the auxiliary locking plate 2 is rotated to the horizontal state and pushed into the rectangular groove at the bottom of the main locking plate 1, the bottom surface of the auxiliary locking plate 2 will be in close contact with the top surface of the protruding plate. Therefore, when the auxiliary locking plate 2 is pushed into the rectangular groove at the bottom of the main locking plate 1, the protruding plates on the inner side of the rectangular groove at the bottom of the main locking plate 1 can limit the rotation of the auxiliary locking plate 2.
[0036] Example 2, based on Example 1, such as Figures 1-7 As shown, the bottom surface of the auxiliary locking plate 2 is on the same plane as the bottom surface of the main locking plate 1. The auxiliary locking plate 2 is also provided with a long strip opening, so when the main locking plate 1 and the auxiliary locking plate 2 are installed on a flat bone surface, they are easier to fit against the outer wall of the bone. The long strip opening on the auxiliary locking plate 2 can also be positioned below the locking hole 3 on the main locking plate 1 after adjustment, which makes it easier to drive the bone screw 4 into the bone.
[0037] The working principle of this embodiment is as follows: After the device is manufactured, the auxiliary locking plate 2 can be rotated horizontally and pushed to the innermost side of the rectangular groove at the bottom of the main locking plate 1. This shortens the overall length of the reduction locking device, making it easier to package and store. When using this device to fix a fracture site, if the bone surface to be fixed is flat, the auxiliary locking plate 2 can be pulled outward slightly to expose the locking holes 3 on the auxiliary locking plate 2. Then, the bone nail 4 can be inserted into the bone through the locking holes 3 on the main locking plate 1 and the auxiliary locking plate 2. If the bone surface to be fixed is bent, the auxiliary locking plate 2 can be pulled outward to the outermost side first. Then, the auxiliary locking plate 2 can be rotated and adjusted under the support of its front and rear round rods, thereby enabling... The main locking plate 1 and the auxiliary locking plate 2 are designed to adapt to bone surfaces with different curvatures. Finally, the bone screw 4 is inserted into the bone through the locking holes 3 on the main locking plate 1 and the auxiliary locking plate 2. During the insertion of the bone screw 4 into the bone, the protrusion on the outer side of the locking block 5 will be embedded in the vertical groove of the L-shaped groove on the inner wall of the locking hole 3. After the bone screw 4 is inserted into the bone, a Phillips screwdriver can be inserted into the Phillips-shaped groove at the top of the adjusting head 6 and rotated 90° clockwise. This allows the locking block 5 to rotate synchronously with the protrusion on its outer side. At this time, the protrusion on the outer side of the locking block 5 will be stuck in the horizontal groove of the L-shaped groove on the inner wall of the locking hole 3. This restricts the vertical displacement of the bone screw 4 in the locking hole 3, thereby firmly locking the main locking plate 1 and the auxiliary locking plate 2 with the bone screw 4.
