[0032] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0033] Reference Figures 1-8As shown, a joint injection precision positioning auxiliary device includes an upper bracket 1 and a lower bracket 2, two of each of the upper bracket 1 and the lower bracket 2 are provided, and the upper bracket 1 corresponds to the lower bracket 2 one by one, a rotating component 3 is provided between the upper bracket 1 and the lower bracket 2, and the upper bracket 1 and the lower bracket 2 are connected by the rotating component 3, an auxiliary component 4 is provided on the side away from each other of the two lower brackets 2, and the two auxiliary components 4 are connected by a first bandage 5, one of the upper brackets 1 and the lower bracket 2 is fixedly installed on the side away from each other, and the other upper bracket 1 and the lower bracket 2 are fixedly installed on the side away from each other, and the telescopic component 6 and the connecting component 7 are connected by an arc plate 8, two first buffer plates 9 are provided between the two upper brackets 1, and the two first buffer plates 9 correspond to the two upper brackets 1 one by one, two second buffer plates 10 are provided between the two lower brackets 2, and the two second buffer plates 10 Corresponding one to one with the two lower supports 2, a third buffer plate 11 is provided under the arc plate 8. When injecting the patient's knee joint, the leg to be injected is placed in the device. Since the leg characteristics of different patients are different and since the curvature of the arc plate 8 is certain, the doctor needs to adjust the length of the telescopic component 6 according to the characteristics of the patient's legs so that the arc plate 8 does not excessively squeeze the patient's legs. In the process of adjusting the telescopic component 6, the connecting component 7 is adjusted along with the adjustment of the telescopic component 6. The patient's legs need to be kept straight during injection, and the rotating component 3 works together with the patient's legs while the legs are kept relaxed. When the patient's legs are in a relaxed state, the doctor fixes the rotating component 3 and determines the injection position with both hands. In the process of determining the injection position, the doctor adjusts the position of the auxiliary component 4. After the injection position is determined, the first bandage 5 is fixed by the auxiliary component 4. The first bandage 5 assists the doctor in injection.

[0034] like Figure 2As shown, the rotating assembly 3 includes a fixed plate 301, two fixed plates 301 are provided, two rotating plates 302 are provided between the two fixed plates 301, and the two rotating plates 302 are rotatably connected to the two fixed plates 301, the two rotating plates 302 are symmetrically distributed about the center of the fixed plate 301, the two rotating plates 302 are fixedly connected to the upper bracket 1 and the lower bracket 2 respectively, and the two rotating plates 302 are fixedly installed with a sector gear 303 on the side close to each other, and the two sector gears 303 are meshed with each other, and the fixed plate 301 corresponding to the lower bracket 2 is provided with a first insertion groove 304 on the side away from the lower bracket 2, and the first insertion groove 304 corresponds to the rotating plate 302 inside There are several second insertion slots 305, which are distributed around the center line of the sector gear 303. An insertion rod 306 is provided inside the first insertion slot 304. When the patient's knee joint changes, the patient's thigh and calf respectively drive the upper limb plate and the lower limb plate to rotate, and the upper limb and the lower limb both drive the rotating plate 302 to rotate around the center of the sector gear 303. When the patient's legs are in a relaxed state, the doctor inserts the insertion rod 306 into the first insertion slot 304 and the corresponding second insertion slot 305, thereby limiting the patient's legs and preventing the patient from bending his legs due to pain during the injection process, thereby causing secondary injury to the patient.

[0035] like Figure 3 As shown, the auxiliary component 4 includes a main board 401, a sliding groove 402 is provided on the side of the main board 401 away from the lower limb plate, a guide rod 403 is fixedly installed on the inner wall of the sliding groove 402, and a slider 404 corresponding to the sliding groove 402 is sleeved on the outer surface of the guide rod 403, and a side plate 405 is fixedly installed on the left and right sides of the slider 404, a rebound mechanism 406 is provided between the two side plates 405, and a fixed rod 4061 and a rotating rod 4062 are provided inside the rebound mechanism 406, and the outer surfaces of the fixed rod 4061 and the rotating rod 4062 are sleeved with a push rod 407, and the two push rods 407 are fixed to the slider. The center line of 404 is symmetrically distributed, and a fixed claw 408 corresponding to the first strap is provided between the two push rods 407. The fixed claw 408 is fixedly connected to the two push rods 407. In the process of determining the injection position, the slide moves along the axial direction of the guide rod 403. In the process of determination, the rebound mechanism 406 makes the first strap in a tight state, realizing real-time close integration with the knee joint. After determining the injection position, the doctor pushes the push rod 407 to make the fixed claw 408 fix the current state of the first strap, preventing the rebound component from changing the state of the first strap, and ensuring the injection position determined by the first strap.

[0036] like Figure 4As shown, the rebound mechanism 406 includes a fixed rod 4061 and a rotating rod 4062, the end of the fixed rod 4061 close to the side plate 405 is fixedly connected to the side plate 405, the end of the fixed rod 4061 away from the side plate 405 is fixedly installed with a first circular plate 4063, the rotating rod 4062 is rotatably connected to the side plate 405 away from the fixed rod 4061, and a second circular plate 4064 is fixedly installed on the outer surface of the rotating rod 4062 corresponding to the first circular plate 4063. The rotating rod 4062 is rotatably connected to the fixed rod 4061, and the first circular plate 4063 and the second circular plate 4064 are rotatably connected. A chamber 4065 is opened between the first circular plate 4063 and the second circular plate 4064, and a spiral spring 4066 is provided inside the chamber 4065. A baffle 4 is provided at the end of the spiral spring 4066 away from the rotating rod 4062. 067, the baffle 4067 is fixedly connected to the first circular plate 4063, and the two ends of the spiral spring 4066 are respectively fixedly connected to the baffle 4067 and the rotating rod 4062. The spiral spring 4066 is preset with a certain elastic potential energy. When the equipment is in the initial state, the spiral spring 4066 uses the rotating rod 4062 to make the first bandage 5 in a tight state and the length of the first strap wound on the rotating rod 4062 is the same. In the process of determining the injection position, the doctor pushes the first bandage 5 close to one of the auxiliary components 4, and the corresponding spiral spring 4066 in the rebound mechanism 406 rotates the rotating rod 4062 so that the rotating rod 4062 retracts the first strap. The elastic potential energy of the spiral spring 4066 in the rebound mechanism 406 in the other auxiliary component 4 increases, thereby ensuring that the first strap is always in close contact with the patient's leg.

[0037] like Figure 5As shown, the telescopic component 6 includes a first main body 601, a first movable groove 602 is opened inside the first main body 601, a first movable plate 603 is set inside the first movable groove 602, the first movable plate 603 is fixedly connected to the arc plate 8 and the third buffer plate 11, a plurality of third insertion grooves 604 are opened inside the first movable plate 603, and the plurality of third insertion grooves 604 are linearly distributed along the edge direction of the first movable plate 603, a fourth insertion groove 605 identical to the third insertion groove 604 is opened on the side of the first main body 601, an insertion plate 606 is set inside the fourth insertion groove 605, and a limiting plate 607 is fixedly installed on the end surface of the insertion plate 606 corresponding to the first main body 601. The first guide rods 608 are fixedly installed on the upper and lower sides of the fourth insertion slot 605, and the limit plate 607 is slidably connected to the two first guide rods 608. The outer surface of the first guide rod 608 is sleeved with a first spring 609, and the two ends of the first spring 609 are respectively fixedly connected to the first guide rod 608 and the limit plate 607. When adjusting the telescopic assembly 6, the staff pulls the limit plate 607 to make the insertion plate 606 leave the fourth insertion slot 605, and the doctor pushes the arc plate 8 to move the first movable plate 603. When it moves to the appropriate position, the first spring 609 pushes the limit plate 607 to make the first movable plate 603 quickly enter the corresponding third insertion slot 604, completing the deployment of the telescopic assembly 6.

[0038] like Figure 6 As shown, the connecting component 7 includes a second main body 701, a second movable groove 702 is opened inside the second main body 701, a second movable plate 703 is arranged inside the second movable groove 702, and a second guide rod 704 is fixedly installed on the inner wall of the second movable groove 702 corresponding to the second movable plate 703, and a second spring 705 is sleeved on the outer surface of the second guide rod 704, and the two ends of the second spring 705 are respectively fixedly connected to the inner wall of the second movable groove 702 and the second movable plate 703. During the expansion of the telescopic component 6, the second spring 705 pushes the second movable plate 703, and the second spring 705 provides support for the second movable plate 703, so that the second movable plate 703 moves synchronously with the first movable plate 603 to prevent the second movable plate 703 from getting stuck.

[0039] like Figure 7 As shown, a positioning groove 12 is provided inside the first strap, and a fixing ring 13 is fixed inside the positioning groove 12. The doctor places a finger in the fixing ring 13, and drives the first strap close to the auxiliary component 4 on one side through the fixing ring 13. The fixing ring 13 increases the force on the finger and the first strap, and prevents the first strap from being deformed, thereby ensuring the accuracy of the injection positioning.

[0040] like Figure 8As shown, the outer surface of the first movable plate 603 is provided with a buffer pad 14, and the buffer pad 14 is fixedly connected to the arc plate 8 and the third buffer plate 11. When the telescopic component 6 is stored, the buffer pad 14 absorbs the impact force between the arc plate 8 and the third buffer plate 11 and the first main body 601, avoiding stress concentration and causing cracks or damage in the connection parts.

[0041] like Figure 1 As shown, the first buffer plate 9 is connected to the upper bracket 1 through a first ear 15, the second buffer plate 10 is connected to the lower bracket 2 through a second ear 16, and the arc plate 8 is connected to the third buffer plate 11 through two third ears 17. The two first ears 15, the two second ears 16 and the two third ears 17 are all connected by a second strap 18. The ear, as a connecting component, provides a stable connection point between the buffer plate and the corresponding frame (upper limb plate, lower limb plate) and between the arc plate 8 and the third buffer plate 11. By fixing the buffer plate and the frame or the arc plate 8 and the third buffer plate 11 respectively on the ear, it can be ensured that they maintain a relatively fixed position relationship during the use of the device and will not easily fall off or shift, thereby ensuring the integrity and stability of the overall structure of the device. The patient's legs can be fixed in the device through the second strap 18.

[0042] like Figure 3 As shown, a magnet 19 is provided on the bottom surface of the main board 401 corresponding to the slider 404. The slider 404 is made of metal. The magnet 19 can quickly fix the slider 404 in a suitable position to prevent the slider 404 from sliding and causing changes in the injection positioning.

[0043] Working principle: When injecting the patient's knee joint, the leg to be injected is placed in the device. Since the leg characteristics of different patients are different and the curvature of the arc plate 8 is fixed, the doctor needs to adjust the length of the telescopic component 6 according to the characteristics of the patient's leg so that the arc plate 8 does not squeeze the patient's leg too much. When adjusting the telescopic component 6, the staff pulls the limit plate 607 to make the insertion plate 606 leave the fourth insertion slot 605. The doctor pushes the arc plate 8 to move the first movable plate 603. When it moves to the appropriate position, the first spring 609 pushes the limit plate 607 to make the first movable plate 603 quickly enter the corresponding third insertion slot 604, the expansion of the telescopic component 6 is completed, and at the same time, the second spring 705 in the connecting component 7 pushes the second movable plate 703, and the second spring 705 provides support for the second movable plate 703, so that the second movable plate 703 moves synchronously with the first movable plate 603. When the telescopic component 6 is fixed, the doctor fixes the patient's legs in the device through the second strap 18. During the injection, the patient's legs need to be kept straight. In the process of keeping the patient's legs relaxed, the rotating component 3 works together, and the upper limbs and lower limbs drive the rotating plate 302 to rotate around the center of the sector gear 303. When the patient's legs are in a relaxed state, The doctor inserts the insertion rod 306 into the first insertion slot 304 and the corresponding second insertion slot 305, thereby limiting the position of the patient's leg. In the process of determining the injection position, the doctor places a finger in the fixing ring 13, and drives the first bandage close to the auxiliary component 4 on one side through the fixing ring 13. At the same time, the doctor removes the magnet 19 to release the slider 404 from the fixed state. The doctor adjusts the position of the slider 404 in the auxiliary component 4. During the movement of the slider 404, the spiral springs 4066 on both sides keep the first bandage 5 in a tight state through the rotating rod 4062. The doctor pushes the first bandage 5 close to one of the auxiliary components 4 The corresponding spiral spring 4066 in the rebound mechanism 406 rotates the rotating rod 4062 so that the rotating rod 4062 retracts the first strap, and the elastic potential energy of the spiral spring 4066 in the rebound mechanism 406 in the other auxiliary component 4 increases, thereby ensuring that the first strap is always in close contact with the patient's leg. After determining the injection position, the doctor places the magnet 19 under the main board 401 corresponding to the slider 404 to fix the slider 404. The doctor pushes the push rod 407 to make the fixing claw 408 fix the current state of the first strap, preventing the rebound component from changing the state of the first strap and ensuring the injection position determined by the first strap.
