A sliding groove is provided at one end of the connecting plate away from the rotating disk, and the plurality of rotating components can be slidably arranged in the sliding groove.

[0032] The aforementioned finger fracture fixation device provides a first movable joint between a fixing seat and a connecting rod, enabling movement of the joint between the wrist and palm. A second movable joint between a rotating disk and a connecting plate enables rotation of the joint between the wrist and palm. Multiple rotating assemblies and multiple mounting finger cuffs enable movement of the joints between the palm and each finger. The multiple rotational arrangements provide relief to each joint, increasing the flexibility of the device and reducing the occurrence of complications.

[0033] The following embodiments of the present application are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0034] according to Figures 1-4 In an embodiment of the present application, a finger fracture fixation device 100 is provided, which includes a first movable joint 10, a second movable joint 20 and a third movable joint.

[0035] Among them, the first movable joint 10 includes a fixed seat 11 and a connecting rod 12, the fixed seat 11 is provided with a rotation groove 11a, and the connecting rod 12 is rotatably arranged in the rotation groove 11a; the second movable joint 20 includes a rotating disk 21 and a connecting plate 22, one end of the rotating disk 21 is fixed on the connecting rod 12, and the other end is fixed on the connecting plate 22; the third movable joint 30 includes a plurality of rotating components 31 and a plurality of mounting finger sleeves 32 connected to the plurality of rotating components 31, and the connecting plate 22 is provided with a sliding groove 22a at one end away from the rotating disk 21, and the plurality of rotating components 31 are slidably arranged in the sliding groove 22a.

[0036] Specifically, the fixing frame is an annular structure that is used to mount the wrist, allowing the wrist to be inserted into the fixing frame. The rotating groove 11a is a groove-shaped groove with openings on three sides. The connecting rod 12 is placed in the rotating groove 11a, allowing the connecting rod 12 to rotate within the rotating groove 11a. The second movable joint 20 is the active point on the back of the hand. The rotating disk 21 is located at the joint between the wrist and the palm, allowing the joint to move between the wrist and the palm. The connecting plate 22 is a fan-shaped structure, similar in shape to the palm, providing a support position for the palm. The connecting plate 22 is provided with a sliding groove 22a, similar in shape to the fan-shaped structure of the connecting plate 22, allowing the rotating assembly 31 to move within the sliding groove 22a. The sliding groove 22a is used to connect the multiple rotating assemblies 31 of the third movable joint 30. The multiple rotating assemblies 31 on the sliding groove 22a serve as the active points at the joints between the fingers and the palm. The multiple rotating assemblies 31 slide within the sliding groove 22a, allowing each finger to freely close and open.

[0037] Furthermore, the injured finger is inserted into the mounting finger sleeve 32, ensuring that the sleeve fits snugly against the surface of the finger. The wrist is secured to the mounting base 11. By moving the palm of the hand up and down around the wrist joint, the connecting rod 12 driving the first movable joint 10 rotates up and down relative to the mounting base 11. By rotating the palm of the hand left and right around the wrist joint, the rotating disk 21 is operated, causing the rotating disk 21 at one end connected to the connecting plate 22 to move left and right relative to the connecting rod 12 at the other end of the rotating disk 21. By adjusting the distance between the fingers, the fingers can be closed or opened. When the fingers are opened or closed, the mounting finger sleeve 32 drives the connected rotating assembly 31 to move within the sliding groove 22a, thereby moving the joints between the fingers. When the fingers move up and down around the joints between the palms, the mounting finger sleeve 32 can move around the rotating assembly 31, allowing the first movable joint 10 to move up and down relative to the second movable joint 20. Once all components are correctly adjusted, the device provides a stable and comfortable fixation environment for the fingers, facilitating fracture healing.

[0038] In a specific embodiment, the rotation slot 11 a includes a first support rod 111 , which is disposed in the rotation slot 11 a , and the connecting rod 12 includes a second support rod 121 , which is connected to the first support rod 111 .

[0039] Specifically, the first support rod 111 and the fixed base 11 are integrally structured, and the second support rod 121 and the connecting rod 12 are integrally structured. The first support rod 111 and the second support rod 121 serve as support points for the connecting rod 12 during rotation, thereby increasing the stability and durability of the rotation slot 11a and ensuring that the connecting rod 12 does not deviate from the track during rotation, thereby ensuring the overall stability and reliability of the device. The first support rod 111 and the second support rod 121 can be connected by plug-in connection or by a rotating shaft, so that the connecting rod 12 can rotate around the first support rod 111 and the second support rod 121, thereby ensuring that when the palm moves up and down around the wrist joint, the connecting rod 12 moves up and down around the first support rod 111 and the second support rod 121.

[0040] In a specific embodiment, a first spring clip 1111 is sleeved on the first support rod 111 , and the connecting rod 12 includes a support column 122 . The support column 122 and the second support rod 121 are arranged side by side, and the output end of the first spring clip 1111 abuts against the support column 122 .

[0041] Specifically, the first spring clip 1111 is mounted on the first support rod 111 and is used to provide elastic pressure to the connecting rod 12. The elastic properties of the first spring clip 1111 can cushion the impact and vibration of the connecting rod 12 during movement, improving the comfort and safety of the device. The support column 122 provides a stable support point for the first spring clip 1111, ensuring that the first spring clip 1111 can effectively function. When rotating the connecting rod 12, the elastic force of the first spring clip 1111 can help the user train wrist strength.

[0042] In a specific embodiment, the rotating disk 21 includes a first rotating portion 211 and a second rotating portion 212 . The first rotating portion 211 is connected to the connecting rod 12 , and the second rotating portion 212 is connected to the connecting plate 22 . The first rotating portion 211 and the second rotating portion 212 are embedded in each other.

[0043] Specifically, the rotating disk 21 is divided into two parts: a first rotating portion 211 and the connecting rod 12 are integrally formed, and a second rotating portion 212 and the connecting plate 22 are integrally formed. The first rotating portion 211 and the second rotating portion 212 are nested together to form a complete rotating disk 21. When the angle of the palm-to-palm joint needs to be adjusted, the adjustment is performed by operating the rotating disk 21. When adjusting the first rotating portion 211 connected to the connecting plate 22, the second rotating portion 212 and the connecting rod 12 remain in a stable fixed state, so that the first rotating portion 211 rotates relative to the rotation of the second rotating portion 212.

[0044] In a specific embodiment, the first rotating part 211 is provided with a connecting column 213, and the second rotating part 212 is provided with a connecting hole 214. The connecting column 213 is aligned with the connecting hole 214, and the connecting column 213 has a threaded hole 213a, and the threaded hole 213a is connected to the connecting column 213 through a screw.

[0045] Specifically, the connecting post 213 is fixed to the first rotating portion 211 by welding or integrally. The connecting post 213 is arranged perpendicular to the end surface of the first rotating portion 211, so that when the first rotating portion 211 and the second rotating portion 212 are engaged, the connecting post 213 can cooperate with the connecting hole 214 of the second rotating portion 212, so that a screw is passed through the connecting hole 214 and connected to the threaded hole 213a of the connecting post 213, thereby installing the first rotating portion 211 and the second rotating portion 212 of the rotating disk 21 together. When the rotating disk 21 is rotated, the first rotating portion 211 can rotate around the connecting post 213, thereby allowing the joints at the palm and wrist to move.

[0046] In a specific embodiment, a second spring clip 215 is formed on the periphery of the connecting post 213 , and a blocking post 216 is provided on the second rotating portion 212 . The output end of the second spring clip 215 abuts against the blocking post 216 .

[0047] Specifically, the second spring clip 215 is sleeved on the periphery of the connecting column 213 to provide an elastic connection mechanism, so that when the rotating disk 21 is rotated, the output end of the second spring clip 215 is abutted against the blocking column 216. The blocking column 216 provides the necessary positioning and fixing function for the entire device, preventing the components from loosening or falling off due to external forces.

[0048] In a specific embodiment, the rotating assembly 31 includes a stud 314, a connecting member 312 and a spring member 313. One end of the stud 314 extends into the sliding groove 22a, and the other end of the stud 314 is connected to the connecting member 312. One end of the spring member 313 is connected to the connecting member 312, and the other end of the spring member 313 is connected to the mounting finger sleeve 32.

[0049] Specifically, the rotating assembly 31 serves as a bridge connecting the connecting plate 22 of the second movable joint 20 and the mounting finger sleeve 32. One end of the stud 314 extends into the sliding slot 22a, and the other end connects to the connector 312, used to transmit torque and drive the entire rotating assembly 31 to slide. The end of the stud 314 extending into the sliding slot 22a is secured by a connecting nut. The other end of the stud 314 can be secured to the connector 312 by welding or by being removably threaded through the connector 312. The spring member 313 can be a spring, providing elastic support and cushioning.

[0050] Furthermore, when the joints between the fingers and the palm need to be moved, as the fingers rotate up and down around the palm joints, the springs of the rotating assembly 31, due to their elastic properties, cause the mounting finger sleeves 32 to rotate up and down around the connecting piece 312. When the fingers are opened or closed, the mounting finger sleeves 32 drive the studs 314 of the rotating assembly 31 to move, causing the studs 314 to move left and right within the sliding slots 22a, thereby moving the joints between the fingers and the palm.

[0051] In a specific embodiment, the connecting member 312 has a long rod 3121 and a connecting seat 3122, the connecting seat 3122 is connected to the stud 314, the long rod 3121 is generated along the bottom extension direction of the connecting seat 3122, and the extending end of the long rod 3121 is connected to the spring member 313.

[0052] Specifically, the connecting seat 3122 is a structure with openings on three sides. The long rod 3121 continues to extend along the bottom, so that the extended end of the long rod 3121 is connected to the spring member 313. By increasing the length of the long rod 3121, the elasticity of the spring member 313 is made stronger, and then the elastic tension between the installation finger sleeve 32 and the connecting plate 22 is adjusted to achieve the up and down rotation of the installation finger sleeve 32 around the connecting member 312.

[0053] In a specific embodiment, the mounting finger sleeve 32 includes a first mounting hole 32a, the connecting member 312 has a second mounting hole 312a, the first mounting hole 32a and the second mounting hole 312a are aligned, wherein; the rotating assembly 31 also includes a fixing member 315, and the fixing member 315 passes through the first mounting hole 32a and the second mounting hole 312a.

[0054] Specifically, the mounting finger cuff 32 is used to wrap and support the patient's finger, ensuring its stability during treatment and reducing finger movement or deformation caused by external forces, thereby promoting fracture healing. The fixing member 315, which can be a bolt or a threaded stud, is inserted through the first mounting hole 32a and the second mounting hole 312a to achieve a stable connection between the components. This allows the mounting finger cuff 32 to rotate around the fixing member 315 as each finger rotates up and down around the joint at the palm.

[0055] In a specific embodiment, the mounting finger sleeve 32 further includes a mounting tube 321 and a mounting rod 322 . One end of the mounting rod 322 is connected to the mounting tube 321 , and the other end is connected to the connecting member 312 .

[0056] Specifically, the mounting tube 321 is used to place fingers, the mounting rod 322 is connected to the connecting member 312, and the mounting rod 322 is connected to the connecting member 312 through the fixing member 315. At the same time, the mounting rod 322 is also connected to the spring member 313, and the elastic force of the spring member 313 is used to pull the mounting rod 322 and the mounting tube 321, so that the first mounting hole 32a on the mounting rod 322 is connected to the connecting member 312.

[0057] The above is only an implementation method of the present application. It should be pointed out that for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present application, but these all fall within the scope of protection of the present application.
