[0047] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0048] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0049] Combine the following Figures 1 to 11 The bone clamp structure 10 provided in this embodiment is described in detail.

[0050] Please refer to Figure 1 as well as Figure 2 The embodiment of the present invention provides a bone clamp structure 10, including a central axis 100, a first clamping leg 200 and a second clamping leg 300; the first clamping leg 200 and the second clamping leg 300 are both connected to the central axis 100, and the first clamping leg 200 and the second clamping leg 300 can rotate relative to each other; the first clamping leg 200 is provided with a first clamping portion 232, and the second clamping leg 300 is provided with a second clamping portion 331, and the first clamping portion 232 and the second clamping portion 331 are used to approach or move away from each other during the relative rotation of the first clamping leg 200 and the second clamping leg 300 to form an adjustable clamping space 400 for clamping bones; a first fitting portion 233 is provided on the side of the first clamping portion 232, and the first fitting portion 233 is used to fit and contact with the bone, and the first fitting portion 233 is used to clamp and fix the bone in the clamping space 400 together with the second clamping portion 331.

[0051] “The first clamping leg 200 and the second clamping leg 300 can rotate relative to each other” includes that the first clamping leg 200 is rotationally connected to the central axis 100, the second clamping leg 300 is fixed to the central axis 100, and the first clamping leg 200 rotates relative to the second clamping leg 300; or the first clamping leg 200 is fixed to the central axis 100, the second clamping leg 300 is rotationally connected to the central axis 100, and the second clamping leg 300 rotates relative to the first clamping leg 200; or both the first clamping leg 200 and the second clamping leg 300 are rotationally connected to the central axis 100, and the first clamping leg 200 and the second clamping leg 300 can both rotate relative to each other.

[0052] During the relative rotation of the first clamping leg 200 and the second clamping leg 300, the first clamping leg 200 and the second clamping leg 300 move closer to or farther from each other, and the first clamping portion 232 and the second clamping portion 331 move closer to or farther from each other simultaneously. A clamping space 400 is formed between the first clamping portion 232 and the second clamping portion 331. During the process of the first clamping portion 232 and the second clamping portion 331 moving closer to each other, the clamping space 400 becomes smaller, so that the bone located in the clamping space 400 can be clamped; during the process of the second clamping portion 331 moving away from each other, the clamping space 400 becomes larger, so that the bone can be placed in the clamping space 400.

[0053] During the operation, the first clamping portion 232 and the second clamping portion 331 pierce the tissue to form an embracing posture against the bone. The first fitting portion 233 is used to fit against the surface of the bone after the first clamping portion 232 pierces the tissue, which helps prevent the second clamping portion 331 from slipping during the process of holding the bone after piercing the tissue.

[0054] Reference Figure 1 In this embodiment, the tip of the second clamping portion 331 extends from the center of the clamping space 400 to the middle of the first fitting portion 233 to hold the bone. Specifically, the tip of the second clamping portion 331 points to the middle of the first fitting portion 233. The second clamping portion 331 holds the bone and presses the bone against the first fitting portion 233, which is not easy to slip.

[0055] Reference Figure 7 In this embodiment, a second fitting portion 332 is provided on the side of the second clamping portion 331, and the second fitting portion 332 corresponds to the position of the first fitting portion 233; the second fitting portion 332 is used to fit in contact with the bone, and the second fitting portion 332 and the first fitting portion 233 are used to clamp and fix the bone in the clamping space 400 together.

[0056] After the first clamping part 232 and the second clamping part 331 pierce the tissue, the first fitting part 233 and the second fitting part 332 both fit with the surface of the bone. The first fitting part 233 and the second fitting part 332 embrace and clamp the bone under the clamping action of the first clamping leg 200 and the second clamping leg 300, and the contact area with the bone is large, which is not easy to slip.

[0057] Reference Figure 1 as well as Figure 7 In this embodiment, the first fitting portion 233 and the second fitting portion 332 are both in an arcuate surface that at least partially fits with the bone surface. The first fitting portion 233 and the second fitting portion 332 at least partially fit with the bone, including two situations of partial fit or full fit. Specifically, the first clamping portion 232 is a tip formed at the bottom end of the first clamping leg 200, which can pierce the tissue, and the side of the tip is cut along the direction from top to bottom to form the first fitting portion 233 in an arcuate shape. The second fitting portion 332 has the same structure as the first fitting portion 233, which will not be repeated.

[0060] Specifically, the first fixing portion 210 is provided with a first fastening hole 510; the first fastener 500 is used to abut against the second fixing portion 320 when fixed with the first fastening hole 510, so that the first clamping leg 200 and the second clamping leg 300 have a movement tendency to approach each other and clamp. Further, the first fastener 500 is a first bolt, and the first fastening hole 510 is a first screw hole. The first bolt is used to gradually approach the second fixing portion 320 during the relative rotation relative to the first screw hole until the second fixing portion 320 is abutted, so that the first clamping leg 200 and the second clamping leg 300 approach each other, until the first clamping portion 232 and the second clamping portion 331 clamp the bone in the clamping space 400, and the rotation of the first bolt is stopped.

[0066] Specifically, the central shaft 100 is installed in the first section hole, and the central shaft 100 is only set in the first section hole, and the central shaft 100 is not set in the second section hole; the connecting rod 900 is passed through the central shaft 100, and the connecting rod 900 extends from the first section hole to the second section hole; the third fastener 225 passes through the fixing hole 226 and enters the second section hole, without the obstruction of the central shaft 100, and the third fastener 225 can directly abut on the connecting rod 900 to achieve the abutment and fixation of the connecting rod 900. Specifically, the groove 222 is set on the first section hole.

[0067] In other embodiments, an avoidance hole may also be provided on the central shaft 100 , the avoidance hole being connected to the fixing hole 226 , and the third fastener 225 passes through the fixing hole 226 and the avoidance hole at the same time to support and fix the connecting rod 900 .

[0068] Reference Figure 1 as well as Figure 2 In this embodiment, the number of the first clamping leg portions 230 is two, and the number of the second clamping leg portion 330 is one; the two second clamping leg portions 330 and the one second clamping leg portion 330 are distributed in a triangular structure to jointly clamp and fix the bone in the clamping space 400.

[0069] The two first clamping legs 230 are arranged at intervals, and the two first clamping legs 230 are connected to the first connecting portion 220. The two first clamping legs 230 have the same shape and structure, and the ends of the two first clamping legs 230 away from the first connecting portion 220 respectively form a first clamping portion 232. The first fixing portion 210, the first connecting portion 220 and the two first clamping legs 230 are integrally formed. The second clamping leg 330 is correspondingly located between the two first clamping legs 230, and the two first clamping legs 230 and the second clamping leg 330 are arranged in a triangular structure, which helps to enhance stability and prevent the first clamping leg 200 and the second clamping leg 300 from deflecting when clamped on the bone.

[0070] Reference Figure 8 In other embodiments, the number of the first clamping leg portion 230 is one, the number of the second clamping leg portion 330 is one, and one first clamping leg portion 230 is arranged opposite to one second clamping leg portion 330 .

[0071] Reference Figure 4 as well as Figure 5 , combined with Fig. 9In this embodiment, the first clamping leg portion 230 also includes a mounting portion 600 disposed on the first connecting portion 220; the mounting portion 600 is provided with an internal thread 640, and a through U-shaped groove 610 is opened on both sides of the internal thread 640, and the U-shaped groove 610 is used for the connecting rod to be inserted, and the connecting rod 900 is used to simultaneously connect at least two bone clamp structures 10; the bone clamp structure 10 also includes a screw plug 630; the screw plug 630 is used to be threadedly connected to the U-shaped groove 610; after the connecting rod 900 is inserted into the U-shaped groove 610, it is pressed and fixed by the screw plug 630.

[0072] Specifically, the top of the U-shaped groove 610 is open. The vertical cross-section of the U-shaped groove 610 is a "U"-shaped structure. When the connecting rod 900 is actually installed, the connecting rod 900 is inserted into the U-shaped groove 610, and then the screw plug 630 is inserted into the U-shaped groove 610 from the top of the U-shaped groove 610 to hold the connecting rod 900 until the connecting rod 900 is pressed and fixed, and the screw plug 630 is threadedly connected and fixed with the U-shaped groove 610. Since the connecting rod 900 is fixed by pressing, the bone clamp structure 10 can be used to clamp and fix bent or curved bones. For example, in combination with Fig. 9 , a connecting rod 900 having the same shape as the bone is used, the connecting rod 900 is inserted into the U-shaped grooves 610 of at least two bone clamp structures 10 at the same time, and is fixed in the U-shaped grooves 610 respectively by screw plugs 630, and at this time the connecting rod 900 is parallel to the bent or curved bone. That is, a bone that is approximately linear is connected by a linear connecting rod 900, and a bone that is bent or curved is connected by a bent or curved connecting rod 900. The fixing method in which the screw plug 630 cooperates with the mounting portion 600 is suitable for fixing the bent or curved connecting rod 900, preventing the connecting rod 900 from flipping over, and improving the stability of the fixation of the bone clamp structure 10.

[0073] As mentioned above, both the “through hole 110” and the “U-shaped groove 610” mentioned above can be used to install the connecting rod 900, and the specific method can be selected according to the specific situation.
