[0024] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the present application can be combined with each other.

[0025] like Figure 1-8As shown, according to one aspect of the present invention, a joint support and positioning device for assisting ankle repair surgery is provided, comprising a base plate 3, a support assembly 8 fixedly connected to the right side of the top center of the base plate 3, an adjustment assembly 9 disposed inside the support assembly 8, the support assembly 8 including a first support rod 801 fixedly connected to the right side of the top center of the base plate 3, a second support rod 802 disposed inside the first support rod 801, and the adjustment assembly 9 disposed between the inside of the first support rod 801 and the inside of the second support rod 802, and the second support rod 802 being slidably connected to the first support rod 801 through the adjustment assembly 9. A support rod 3 803 is fixedly connected to the top, and a positioning component 1 is provided at the top of the support rod 3 803. An auxiliary component 2 is provided above the outer surface of the support rod 2 802, and the auxiliary component 2 is installed with the adjustment component 9 and the positioning component 1. A support plate 4 is fixedly connected to the bottom left side of the base plate 3, and a connecting plate 5 is fixedly connected to the bottom of the support plate 4. Threaded holes 11 are provided at the front and rear of the connecting plate 5. A threaded rod 7 is threadedly connected inside the threaded holes 11. A clamping plate 6 is fixedly connected to the top of the threaded rod 7, and a clamping pad 10 is fixedly connected to the top of the clamping plate 6. During operation, the base plate 3 is first placed on the operating table. The device is placed on the patient's ankle joint. After placement, the threaded rod 7 is rotated and moves within the threaded hole 11. The rotation of the threaded rod 7 then causes the clamping plate 6 and clamping pad 10 to rotate and clamp the bottom edge of the operating table, ensuring a stable installation between the base plate 3 and the surgical drape. Next, the support rod assembly and positioning assembly 1 work together to support and position the patient's ankle joint, assisting the surgeon in performing ankle repair surgery. Therefore, during use, the device uses the support assembly 8 and positioning assembly 1 to support and position the patient's joint, assisting the surgeon. The device allows for smooth ankle repair surgery, resulting in better performance and greater practicality. During use, the height of the positioning component 1 can be adjusted via the adjustment component 9 inside the support component 8, accommodating various user needs. Simultaneously, the auxiliary component 2 allows the positioning component 1 to disengage from the patient's joint during adjustment, re-positioning it after adjustment. This avoids discomfort caused by the positioning component 1 remaining in one position during adjustment, making the device convenient and highly functional.

[0026] In this embodiment, the adjustment component 9 includes a mounting groove 904 located at the center of the support rod 801. The upper surface of the mounting groove 904 communicates with the outside, and the bottom end of the support rod 802 is inserted into the mounting groove 904. Sliding grooves 916 are provided on both the front and rear surfaces of the mounting groove 904. Sliding sliders 915 are slidably connected inside the sliding grooves 916, and the opposite sides of the two sliding sliders 915 are fixedly connected to the lower part of the outer surface of the support rod 802. Multiple evenly distributed slots 905 are provided on both the left and right sides of the mounting groove 904. A through mounting groove 912 is provided at the bottom of the support rod 802. Sliding grooves 912 are provided at the center of both the front and rear surfaces of the mounting groove 912. 918, sliders 917 are slidably connected to both sides of the inner side of the slide groove 918. A pressing rod 911 is fixedly connected between the two sliders 917 on the left and between the two sliders 917 on the right. A spring 919 is fixedly connected between the two sliders 917 inside each slide groove 918. A pressing block 913 is fixedly connected to the opposite end of each of the two pressing rods 911. A locking block 908 is fixedly connected to the opposite end of each of the two pressing rods 911, and the locking block 908 is engaged inside the locking groove 905. An arc-shaped inlet / outlet section 909 is provided on the side of the top and bottom of the locking block 908 away from the center of the inner side of the mounting groove 912. An arc-shaped inlet / outlet section 909 is provided on the side of the top and bottom of the locking block 908 near the center of the inner side of the mounting groove 912. A horizontal limiting section 910 is provided. A second mounting groove 903 is formed at the center of the upper surface of the fourth mounting groove 912. A second extrusion rod 906 is slidably connected inside the second mounting groove 903, and the bottom end of the second extrusion rod 906 is in contact with the side of the extrusion block 913 near the center of the fourth mounting groove 912. A first spring 907 is fitted onto the outer surface of the second extrusion rod 906, with its top end fixedly connected to the outer surface of the second extrusion rod 906 and its bottom end fixedly connected to the inner wall of the second mounting groove 903. A left-right through mounting groove 901 is formed on the upper surface of the second mounting groove 903, and extrusion rods 902 are slidably connected to both the left and right sides of the first mounting groove 901, with the outer surface of the first extrusion rod 902 in contact with the center of the fourth mounting groove 912. The top ends of 906 are fitted together. A spring 914 is sleeved on the outer surface of the first extrusion rod 902. One end of the spring 914, away from the center of the mounting groove 901, is fixedly connected to the outer surface of the first extrusion rod 902. One end of the spring 907, near the center of the mounting groove 901, is fixedly connected to the inner wall of the mounting groove 901. During operation, when the height of the second support rod 802 and the positioning component 1 inside the support component 8 is adjusted using the adjustment component 9, the auxiliary component 2 first releases the pressure on the first extrusion rod 902. After being released from pressure, the first extrusion rod 902 moves under the rebound force of the previously compressed spring 914. Then, after moving, the first extrusion rod 902 releases the pressure on the second extrusion rod 906.After the compression rod 906 is released from compression, it moves under the rebound force of the previously compressed spring 907. Immediately afterward, the compression rod 906 moves to release its pressure on the compression block 913. The rebound force of the previously stretched spring 919, after the compression block 913 is released from compression, drives the slider 917 to slide inside the groove 918. The slider 917, limited by its movement within the groove 918, drives the compression rod 911 and the compression block 913 to move. Then, the movement of the compression rod 911 causes the locking block 908 to move within the slot 905. The movement of the spring 919 is such that the limiting segment 910 of the locking block 908 can only move out of the slot 905, and the arc-shaped inlet / outlet segment 909 of the locking block 908 corresponds to the outlet of the slot 905. Then, the support rod 802 moves so that it moves under the limiting condition of sliding within the slide groove 916 via the slider 915. During the movement of the support rod 802, the locking block 908 is squeezed inside the slot 905 and contracted by the squeezing rod 911. When the squeezing rod 911 moves, it is compressed by the slider 916. 917 moves within the sliding groove 918 under the limiting condition. When slider 917 slides within the sliding groove 918, it will compress spring 919. Then, when block 908 disengages from slot 905 during the movement of support rod 802, and when block 908 moves and the spring 919 corresponding to another slot 905 is compressed, the rebound force causes slider 917 to move within the sliding groove 918, and causes compression rod 911 and block 908 to move and insert into slot 905 to pre-fix the position of support rod 802 after its movement. Therefore, when support rod 802... After 802 is moved to the appropriate position, the locking block 908 will insert into another locking slot 905. Each time the support rod 802 is moved to adjust its height, the locking block 908 is inserted into the locking slot 905 for pre-fixation, facilitating multiple adjustments to find the appropriate position. Once the appropriate position is reached, the auxiliary component 2 presses the compression rod 902, causing the compression rod 911 to move, which in turn moves the limiting section 910 of the locking block 908 into the locking slot 905, firmly limiting the adjusted height of the support rod 802 and ensuring stable support.

[0027] In this embodiment, the auxiliary component 2 includes a connecting thread 205 formed on the outer surface of the second support rod 802. An internally threaded collar 203 is threaded onto the outer surface of the connecting thread 205. A continuous gripping groove 204 is formed at the center of the outer surface of the internally threaded collar 203. An auxiliary collar 206 is fixedly connected to the bottom of the internally threaded collar 203. The auxiliary collar 206 is sleeved on the outer surface of the second support rod 802 and is movably connected to the second support rod 802. The lower part of the inner sidewall of the auxiliary collar 206 is in contact with the end of the first extrusion rod 902 away from the center of the first mounting groove 901. A continuous groove 204 is formed at the center of the inner surface of the auxiliary collar 206. 10. An inner groove 208 is formed at the top inside the support rod 202. A movable block 211 is slidably connected inside the inner groove 208. A through groove 207 is formed on both the left and right sides of the inner groove 208. A limit block 209 is fixedly connected to both sides of the movable block 211. The side of the limit block 209 furthest from the center of the inner groove 208 is inserted into the groove 210 and rotatably connected to it. An inner groove 201 is formed at the center of the support rod 303. An inner groove 212 is formed on the upper surface of the inner groove 208, and the interior of the inner groove 212 communicates with the interior of the inner groove 201. The movable block... Vertical rods 202 are fixedly connected to the top left and right sides of 211, and the top of the vertical rods 202 is set inside the positioning component 1. During operation, when the auxiliary component 2 is used to operate the positioning component 1 and the adjustment component 9, the internal threaded collar 203 is rotated by holding the grip groove 204, causing the internal threaded collar 203 to rotate and move. The rotation and movement of the internal threaded collar 203 drives the auxiliary collar 206 to rotate and move. Then, the rotation and movement of the auxiliary collar 206 drives the moving block 211 to move under the limit of the rotatable connection between the limit block 209 and the groove 210. After the moving block 211 moves, it can drive the vertical rod 202 to move, and after the vertical rod 202 moves, it can... This allows the positioning component 1 to operate. Subsequently, as the auxiliary collar 206 moves, it will also disengage from the squeezing rod 902 of the adjusting component 9. When the auxiliary collar 206 disengages from the squeezing of the adjusting component 9, the vertical rod 202 moves upward, causing the positioning component 1 to disengage. Conversely, when the auxiliary collar 206 squeezes the adjusting component 9, the vertical rod 202 moves downward, causing the positioning component 1 to reposition. Therefore, by using the auxiliary component 2, the positioning component 1 can disengage from the patient's joint during the adjustment of the adjusting component 9. After the adjustment is completed, it will resume positioning, thus avoiding discomfort to the patient caused by the positioning component 1 remaining in position throughout the adjustment process.

During operation, when the positioning assembly 1 is used...The auxiliary component 2 drives the positioning component 1 to work. When the vertical rod 202 of the auxiliary component 2 moves upward, it causes the swing plate 111 to rotate under the action of the rotating rod 121, which is limited by the movable connection between the limiting rod 124 and the limiting groove 123. The rotation of the swing plate 111 causes the connecting rod 113 and the gear 109 to move downward under the limited connection between the limiting rod 116 and the limiting groove 115. When the connecting rod 113 and the gear 109 move, they move under the limited connection of the sliding of the guide block 104 and the guide groove 103. Then the gear 109... The movement of rod 9 drives spur gear 117 to rotate, which in turn drives rotating rod 120 to rotate. After rotating rod 120 rotates, it causes positioning plate 106 and positioning pad 107 to rotate and disengage from their positioning of the patient's joint inside positioning groove 105. When vertical rod 202 moves downwards, it drives connecting rod 113 and gear 109 to move upwards. The upward movement of gear 109 drives spur gear 117 to rotate, which in turn drives positioning plate 106 and positioning pad 107 to rotate, thus positioning the patient's joint inside positioning groove 105.

[0029] In this embodiment, the side of the positioning plate 106 near the center of the positioning groove 105 is set in an arc shape, and the positioning pad 107 is made of sponge material. During operation, this avoids the end of the positioning plate 106 near the center of the positioning groove 105 causing discomfort to the patient, and the sponge material positioning plate 106 is more comfortable when positioning the patient's ankle joint.

[0030] In this embodiment, the top and bottom ends of the second extrusion rod 906 and the side of the extrusion block 913 near the center of the mounting groove 912 and the end of the first extrusion rod 902 away from the center of the mounting groove 901 are all set in an arc shape. During operation, it is convenient to extrude the top end of the second extrusion rod 906, and it is convenient for the bottom end of the second extrusion rod 906 to extrude the extrusion block 913, and it is convenient for the first extrusion rod 902 to be extruded.

[0031] In this embodiment, the bottom end of the threaded rod 7 passes through the bottom of the connecting plate 5 and is fixedly connected to a handle 12. The clamping pad 10 is made of rubber. During operation, the handle 12 facilitates the rotation of the threaded rod 7, and the rubber clamping pad 10 has a good anti-slip effect.

[0032] The working principle of this device is as follows: In use, the base plate 3 is first placed on the operating table and positioned at the patient's ankle joint. After placement, the threaded rod 7 is rotated within the threaded hole 11. This rotation causes the clamping plate 6 and clamping pad 10 to rotate and clamp the bottom edge of the operating table, ensuring a stable connection between the base plate 3 and the surgical instrument. Next, the support rod assembly and positioning assembly 1 work together to support and position the patient's ankle joint. This device assists the surgeon in performing ankle repair surgery. Therefore, in use, the support assembly 8 and positioning assembly 1 work together to support the patient... The device supports and positions the joint to assist doctors in performing ankle repair surgery, ensuring a smooth procedure. This results in a more effective and practical device. During use, the height of the positioning component 1 can be adjusted via the adjustment component 9 inside the support component 8, allowing the device to meet various usage needs. Simultaneously, the auxiliary component 2 allows the positioning component 1 to disengage from the patient's joint during adjustment, re-positioning it after adjustment. This avoids discomfort caused to the patient by the positioning component 1 remaining in one position during adjustment, making the device convenient to use and highly functional.

[0033] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention are also within the protection scope of the present invention.
