Technical Field

[0001] The present application relates to the technical field of sports medicine, and in particular to a post-operative recovery training device and method for joint surgery for sports medicine. Background Art

[0002] The joint surgery postoperative recovery training device for sports medicine is a device for rehabilitation training of patients after joint surgery, aiming to help patients restore joint function, enhance muscle strength and improve joint mobility.

[0003] In the related art, when training the knee joints of patients who have undergone joint surgery, the postoperative recovery training device for sports medicine usually causes the patient's legs to perform linear reciprocating motions in the walking direction. The single training mode leads to poor recovery effects. Summary of the invention

[0004] The embodiments of the present application provide a post-operative recovery training device and method for joint surgery for sports medicine, which can improve the technical problem in the related art that the post-operative recovery training device for joint surgery for sports medicine has a single training mode, resulting in poor recovery effect.

[0005] In a first aspect, the present application provides a postoperative recovery training device for joint surgery for sports medicine, comprising: A support portion having a placement portion for supporting a user's legs, the support portion having a support accommodation space; a rotating portion, located in the support accommodating space and disposed on the support portion; and A plurality of moving parts, wherein the moving parts include a rotating mechanism and a moving mechanism, wherein the rotating mechanism is located in the supporting and accommodating space and is arranged on the rotating part and is in frictional contact with the supporting part, wherein the moving mechanism is partially located in the supporting and accommodating space and is movably arranged on the rotating mechanism, wherein the moving mechanism has a accommodating part for supporting the legs of the user, wherein the accommodating part is located beside the placing part, wherein the moving mechanism is used to clamp the legs of the user and make the legs of the user approach or move away from the supporting and accommodating space in a first direction, and wherein the rotating mechanism is used to drive the moving mechanism to rotate around a first axis; Among them, the rotating part is used to drive each of the rotating mechanisms to rotate around the user's pelvis, and then drive each of the moving mechanisms to rotate, so that the accommodating part moves away from or close to the placing part, the first direction is the direction of gravity, and the first axis is the central axis of the leg bone when the user's leg is clamped by the moving mechanism.

[0006] The above technical solutions in the embodiments of the present application have at least the following technical effects: The joint surgery postoperative recovery training device for sports medicine provided by the embodiment of the present application supports the user's body through the support part to prevent the user from accidentally falling during the recovery training process. The user's thigh and calf are clamped by multiple motion mechanisms respectively, and the user's legs are driven to approach or move away from the support accommodation space along the first direction to simulate the user's walking process, thereby promoting blood return to the lower limbs and relieving muscle tension and fatigue, thereby indirectly benefiting the health of the knee joint. The motion mechanism that clamps the user's leg is driven by the rotating mechanism to rotate around the first axis, so that the user's thigh and calf are relatively rotated outward or inward at a certain angle, and the motion mechanism can realize oblique leg movement when driving the user's leg to move. The rotating part drives each rotating mechanism to rotate around the user's pelvis as the center, and then drives each motion mechanism to rotate, so that the accommodation part of each motion mechanism is away from or close to the placement part. When one leg of the user is on the placement part, it can simulate the situation where the user spreads his legs.

[0007] In a second aspect, an embodiment of the present application provides a control method for a postoperative recovery training device for joint surgery for sports medicine, which is applied to the postoperative recovery training device for joint surgery for sports medicine in the above embodiment, and the method comprises: Allowing the user to lie flat on the support portion, and fixing the thigh and calf of at least one leg of the user to at least one of the movement mechanisms respectively, and then fixing the user's body to the support portion; Clamping the user's legs through each of the movement mechanisms and moving the user's legs closer to or farther from the support and accommodation space along the first direction, so that the user's legs are higher than or lower than the placement portion; When the thigh and calf of the user are respectively clamped by at least one of the movement mechanisms, the movement mechanism is driven to rotate around the first axis by the rotation mechanism, so that the thigh and calf of the user are relatively rotated outward or inward by a preset angle; When the thigh and calf of the user are respectively clamped by at least one of the movement mechanisms and one leg of the user is located on the placement portion, the rotation portion drives the movement portions to rotate as a whole around the user's pelvis.

[0008] As can be seen from the above, the control method of the joint surgery postoperative recovery training device for sports medicine provided by the embodiment of the present application prevents the user from accidentally falling during the recovery training by allowing the user to lie flat on the support part, and fixing the thigh and calf of at least one leg of the user to at least one motion mechanism respectively, and then fixing the user's body to the support part. Through each motion mechanism, the user's legs are clamped and the user's legs are respectively moved closer to or away from the support accommodating space at different distances in the first direction, so that the user's legs are higher than or lower than the placement part, simulating the user's walking process to promote blood return to the lower limbs and relieve muscle tension and fatigue, which is beneficial to the health of the knee joint. The motion mechanism is driven by the rotating mechanism to rotate around the first axis, so that the user's thigh and calf are relatively rotated outward or inward at a preset angle to stretch the muscles and ligaments around the knee joint and enhance the stability and flexibility of the knee joint. The rotating part drives each motion part to rotate as a whole with the user's pelvis as the center, thereby stretching the knee joint, enhancing the strength of the muscles around the knee joint and improving the stability of the knee joint.

[0019] The joint surgery postoperative recovery training device for sports medicine is a device for rehabilitation training of patients after joint surgery, aiming to help patients restore joint function, enhance muscle strength and improve joint mobility.

[0020] In the related art, when training the knee joints of patients who have undergone joint surgery, the postoperative recovery training device for sports medicine usually causes the patient's legs to perform linear reciprocating motions in the walking direction. The single training mode leads to poor recovery effects.

[0021] Based on this, in order to improve the technical problem in the related art that the single training mode of the postoperative recovery training device for joint surgery in sports medicine leads to poor recovery effect, the embodiment of the present application provides the following solution.

[0022] See also Figure 1 The embodiment of the present application provides a sports medicine joint surgery postoperative recovery training device 100, which includes a support part 10, a rotating part 20 and a plurality of moving parts 30, wherein: The support portion 10 has a placement portion 13 for supporting the legs of a user, and the support portion 10 has a support accommodation space.

[0023] The rotating portion 20 is located in the supporting accommodating space and is disposed on the supporting portion 10 .

[0024] The moving part 30 includes a rotating mechanism 31 and a moving mechanism 32. The rotating mechanism 31 is located in the supporting accommodating space and is arranged on the rotating part 20, and is in friction contact with the supporting part 10. The moving mechanism 32 is partially located in the supporting accommodating space and is movably arranged on the rotating mechanism 31. The moving mechanism 32 has a accommodating part 33 for supporting the user's legs. The accommodating part 33 is located next to the placing part 13. The moving mechanism 32 is used to clamp the user's legs and make the user's legs approach or move away from the supporting accommodating space along a first direction. The rotating mechanism 31 is used to drive the moving mechanism 32 to rotate around a first axis.

[0025] Among them, the rotating part 20 is used to drive each rotating mechanism 31 to rotate around the user's pelvis, that is, when each movement mechanism 32 is fixed to the user's leg, the outer side of the user's leg is rotated along a horizontal plane around the user's pelvis to approach the outer side of the user's torso, thereby driving each movement mechanism 32 to rotate, so that the accommodating part 33 is away from or close to the placement part 13, the first direction is the direction of gravity, and the first axis is the central axis of the leg bone when the user's leg is clamped by the movement mechanism 32, that is, the length direction or extension direction of the leg bone.

[0026] It can be understood that the support part 10 is a shell that can provide support for the user. For example, the support part 10 can be an aluminum shell, a plastic shell, etc., but it is not limited to this. The rotating part 20 is a device that can drive the rotating mechanism 31 to rotate. For example, the rotating part 20 can be a servo motor, a DC motor, etc., but it is not limited to this. The rotating mechanism 31 is a device that can drive the motion mechanism 32 to rotate around the first axis. For example, the rotating mechanism 31 can be an electric rocker, a drive motor, etc., but it is not limited to this. The motion mechanism 32 is a device that can clamp the user's legs and drive the user's legs to move closer to or away from the support accommodation space along the first direction. For example, the motion mechanism 32 can include a driving mechanism (double-acting cylinder, guide rod cylinder, etc.) and a clamping device (electric clamp, pneumatic clamping device, etc.) arranged on the power output end of the driving mechanism, but it is not limited to this.

[0027] As can be seen from the above, the joint surgery postoperative recovery training device 100 for sports medicine provided by the embodiment of the present application supports the user's body through the support part 10 to prevent the user from accidentally falling during the recovery training process. The user's thigh and calf are clamped by multiple motion mechanisms 32 respectively, and the user's legs are driven to approach or move away from the support accommodation space along the first direction to simulate the user's walking process, thereby promoting blood return to the lower limbs and relieving muscle tension and fatigue, thereby indirectly benefiting the health of the knee joint. The motion mechanism 32 that clamps the user's leg is driven by the rotating mechanism 31 to rotate around the first axis, so that the user's thigh and calf are relatively rotated outward or inward at a certain angle, and the motion mechanism 32 can realize oblique leg movement when driving the user's leg to move. The rotating part 20 drives each rotating mechanism 31 to rotate around the user's pelvis as the center, and then drives each motion mechanism 32 to rotate, so that the accommodation part 33 of each motion mechanism 32 is away from or close to the placement part 13. When one leg of the user is located on the placement part 13, it can simulate the situation where the user spreads his legs.

[0028] In some embodiments, see Figure 1 The supporting portion 10 includes a supporting member 11 and a supporting mechanism 12 .

[0029] The support member 11 has a support accommodation space, and the support member 11 is used to support the lower body of the user. The support member 11 has a placement portion 13 .

[0030] The support mechanism 12 is rotatably disposed on the support member 11 , and the support mechanism 12 is used to support the upper body of the user.

[0031] The rotating portion 20 is disposed on the supporting member 11 , and the rotating mechanism 31 is in frictional contact with the supporting member 11 .

[0032] It can be understood that the support member 11 is a shell, for example, the support member 11 can be an aluminum shell, a plastic shell, etc., but not limited thereto. The support mechanism 12 is a device capable of fixing the upper body of the user, for example, the support mechanism 12 can include a support plate (aluminum plate, rubber plate, etc.) and a fixing device (elastic fixing belt, external fixing bracket), etc., but not limited thereto, wherein the support plate is rotatably arranged on the support member 11, and the fixing device is arranged on the support plate.

[0033] With such arrangement, when the user needs to perform recovery training, the user can first sit on the support member 11, place one leg on the placement portion 13, and the other leg on the movement mechanism 32, and then fix the upper body to the support mechanism 12 and adjust the rotation angle of the support mechanism 12 to rotate the support mechanism 12 to a position that is conducive to the user's recovery training, thereby preventing the user from accidentally falling during the recovery training.

[0034] In some embodiments, see Figure 1and Figure 2 The rotating part 20 includes a rotating driving member 21 and a rotating plate 22 .

[0035] The rotation driving member 21 is located in the support accommodating space and is disposed on the support portion 10 .

[0036] The rotating plate 22 is located in the supporting accommodation space and is connected to the rotating shaft of the rotating driving member 21 .

[0037] The rotating mechanism 31 is disposed on the rotating plate 22 , and the rotating driving member 21 is used to drive the rotating plate 22 to rotate around the rotating shaft of the rotating driving member 21 .

[0038] It can be understood that the rotating drive member 21 is a driving device that can drive the rotating plate 22 to rotate. For example, the rotating drive member 21 can be a DC motor, a stepping motor, etc., but not limited thereto. The rotating plate 22 is a plate-like structure. For example, the rotating plate 22 can be an aluminum plate, a plastic plate, etc., but not limited thereto. The rotating part 20 drives each rotating mechanism 31 to rotate around the user's pelvis. That is, when the user's pelvis is located directly above the rotating drive member 21, the rotating drive member 21 drives the rotating plate 22 to rotate around the rotation axis of the rotating drive member 21, thereby driving each rotating mechanism 31 to rotate around the rotation axis of the rotating drive member 21.

[0039] In this arrangement, when one leg of the user is located on the placement portion 13 and the other leg is clamped by each movement mechanism 32, the rotating drive member 21 can drive the rotating plate 22 to rotate and move the rotating plate 22 away from the support accommodating space, so as to drive the rotating mechanism 31 away from the support accommodating space, and then drive the movement mechanism 32 away from the support accommodating space, thereby driving the user's legs away from the placement portion 13 along the same horizontal plane, so as to simulate the situation where the user spreads his legs.

[0040] In some embodiments, see Figure 1 and Figure 2 The rotating mechanism 31 includes a rotating moving component 311 and a rotating driving component 312 The rotational moving component 311 is located in the supporting accommodation space, and is disposed on the rotating portion 20 , and is in frictional contact with the supporting portion 10 . An arc-shaped moving sliding groove 313 is formed on the rotational moving component 311 .

[0041] The rotary driving member 312 is rotatably disposed on the rotary moving assembly 311 .

[0042] The motion mechanism 32 is movably disposed on the rotating moving component 311 and connected to the power output end of the rotating driving member 312. The rotating driving member 312 is used to drive the motion mechanism 32 to move along the arc-shaped moving slot 313, and the rotating part 20 is used to drive the rotating moving component 311 to rotate.

[0043] It can be understood that the rotating moving assembly 311 is a device that can provide support for the motion mechanism 32. For example, the rotating moving assembly 311 can be an aluminum support frame, a copper support frame, etc., but is not limited thereto. The rotating driving member 312 is a driving device that can drive the motion mechanism 32 to move along the arc-shaped moving slide 313. For example, the rotating driving member 312 can be a guide rod cylinder, a double-axis cylinder, etc., but is not limited thereto.

[0044] With such arrangement, when the user's legs need to be rotated outward as a whole, each rotating driving member 312 simultaneously drives one end of the connected motion mechanism 32 close to the rotating moving assembly 311 to move close to the placement portion 13 along the arc-shaped moving slot 313. While the height of one end of the motion mechanism 32 close to the rotating moving assembly 311 is rising, the other end of the motion mechanism 32 is fixed to the user's legs, so that the center of gravity of the fixed legs is shifted outward, thereby causing the user's legs to rotate outward as a whole. After the user's legs rotate outward, the motion mechanism 32 can drive the user's legs to move closer to or away from the support accommodation space along the joint movement direction of the user's legs, so as to achieve oblique movement of the user's legs.

[0045] In some embodiments, see 1 and Figure 2 The rotating moving assembly 311 includes a moving support rod 3111 , a moving plate 3112 , a plurality of moving wheels 3113 and a moving support member 3114 .

[0046] The movable support rod 3111 is disposed on the rotating part 20 .

[0047] The moving plate 3112 is disposed on one end of the moving support rod 3111 .

[0048] A plurality of moving wheels 3113 are disposed on the moving plate 3112 and are in rolling and frictional contact with the supporting portion 10 respectively.

[0049] The movable support member 3114 is disposed on the other end of the movable support rod 3111 , and the movable support member 3114 defines an arc-shaped movable sliding groove 313 .

[0050] The rotary driving member 312 is rotatably disposed on the movable support rod 3111 , and the motion mechanism 32 is movably disposed on the movable support member 3114 .

[0051] It can be understood that the movable support rod 3111 is a rod-shaped structure, for example, the movable support rod 3111 can be an aluminum rod, a copper alloy rod, etc., but not limited thereto. The movable plate 3112 is a plate-shaped structure, for example, the movable plate 3112 can be a copper plate, an aluminum plate, etc., but not limited thereto. The movable wheel 3113 is a wheel, for example, the movable wheel 3113 can be a 360-degree free-rotating wheel, a brake-type movable pulley, etc., but not limited thereto. The movable support member 3114 is a support mechanism having an arc-shaped movable groove, for example, the movable support member 3114 can be an arc-shaped support seat, an arc-shaped support fixture, etc., but not limited thereto. In this way, the moving support rod 3111, the moving plate 3112 and the moving support member 3114 provide support for the moving mechanism 32. By setting the moving slide groove to an arc shape, the moving mechanism 32 can change its height when moving along the arc moving slide groove 313, thereby changing the center of gravity of the clamped leg. When the moving mechanism 32 moves along the arc moving slide groove 313 to the closest to the placement portion 13, the clamped leg rotates outward at the maximum angle. When the moving mechanism 32 moves along the arc moving slide groove 313 to the farthest from the placement portion 13, the clamped leg rotates inward at the maximum angle. By making the moving wheel 3113 roll and frictionally contact with the support portion 10, the moving plate 3112 can move more smoothly when driven to rotate.

[0052] In some embodiments, see Figures 1 to 3 The motion mechanism 32 includes a motion driving member 321 and a fixing mechanism 322 .

[0053] The motion driving member 321 is located in the supporting accommodation space and is movably disposed on the moving supporting member 3114 .

[0054] The fixing mechanism 322 is partially located in the supporting accommodation space and is rotatably disposed on the power output end of the motion driving member 321 . The fixing mechanism 322 is used to clamp the legs of the user, and the fixing mechanism 322 has an accommodation portion 33 .

[0055] The motion driving member 321 is used to drive the fixing mechanism 322 to move closer to or away from the supporting accommodation space along a first direction, and the rotating driving member 312 is used to drive the motion driving member 321 to move along the arc-shaped moving sliding groove 313 .

[0056] It can be understood that the motion driver 321 is a driving device that can drive the fixing mechanism 322 to move closer to or away from the supporting accommodation space. For example, the motion driver 321 can be a guide rod cylinder, a dual-axis cylinder, etc., but is not limited to this. The fixing mechanism 322 is a device that can clamp the user's legs. For example, the fixing mechanism 322 can be an electric clamp, a pneumatic clamping device, etc., but is not limited to this. While the rotating driver 312 drives the motion driver 321 to move along the arc-shaped moving groove 313 from the lowest point of the arc-shaped moving groove 313 to the high points on both sides of the arc-shaped moving groove 313, the motion driver 321 can shorten the power output end so that the height of the fixing mechanism 322 connected to the power output end of the motion driver 321 remains unchanged.

[0057] With such a configuration, when the user's legs are placed on the accommodation portion 33, the fixing mechanism 322 can clamp the user's legs, so that the user's legs are fixed in position with the fixing mechanism 322; when the user's legs are clamped by the fixing mechanism 322, the motion driving member 321 can drive the fixing mechanism 322 to approach or move away from the supporting accommodation space along the driving direction of the motion driving member 321, so as to simulate the user walking. Each motion driving member 321 can adjust the height of the connected fixing mechanism 322 separately.

[0058] In some embodiments, see Figure 2 and Figure 3 The fixing mechanism 322 includes a first fixing member 3221 , a rotating connection mechanism 3222 , a second fixing member 3223 and a pressing assembly 3224 .

[0059] The first fixing member 3221 has a first fixing accommodation space and an accommodation portion 33 .

[0060] The rotation connection mechanism 3222 is disposed on a side of the first fixing member 3221 close to the motion driving member 321 , and is rotationally connected to a power output end of the motion driving member 321 .

[0061] The second fixing member 3223 is partially located in the first fixing accommodation space and is movably disposed on the first fixing member 3221 .

[0062] The pressing assembly 3224 is disposed on the first fixing member 3221 .

[0063] A leg accommodating space for accommodating the user's legs is formed between the first fixing member 3221, the second fixing member 3223 and the pressing component 3224. The second fixing member 3223 is used to approach the first fixing member 3221 along the first fixed accommodating space and contact the user's legs to fix the side of the user's legs to the first fixing member 3221. The pressing component 3224 is used to approach the leg accommodating space and contact the user's legs to fix the front of the user's legs to the first fixing member 3221.

[0064] It can be understood that the first fixing member 3221 is a bent plate-like structure. For example, the first fixing member 3221 can be an "L"-shaped plate, a "C"-shaped plate, etc., but is not limited thereto. The rotating connection mechanism 3222 is a mechanism that can rotate in a direction parallel to the length direction of the user's legs. For example, the rotating connection mechanism 3222 can include a connecting plate (aluminum plate, copper plate, etc.) and a rotating joint (coupling, universal joint, etc.), etc., but is not limited thereto, wherein the rotating joint is rotatably arranged on the connecting plate, and the rotating joint is connected to the power output end of the motion driving member 321. The second fixing member 3223 is a bent plate-like structure. For example, the first fixing member 3221 can be an "L"-shaped plate, a "C"-shaped plate, etc., but is not limited thereto. The pressing component 3224 is a device that can approach the user's legs and contact the user's legs so that the user's legs are simultaneously contacted by the pressing component 3224 and the first fixing member 3221. For example, the pressing component 3224 may include a driving device (guide rod cylinder, double-axis cylinder, etc.) and a contact plate (rubber plate, plastic plate, etc.), but is not limited to this. The driving device can be arranged on the first fixing member 3221, and the contact plate can be arranged on the power output end of the driving device. The driving device is used to drive the contact plate to approach and contact the user's legs.

[0065] With such a configuration, when the user's legs are placed on the accommodating portion 33, the second fixing member 3223 is moved so that the second fixing member 3223 is close to and in contact with the user's legs, and the user's legs are simultaneously in contact with the second fixing member 3223 and the first fixing member 3221, so as to achieve preliminary fixation of the user's legs, and then the pressing component 3224 is moved close to the user's legs and in contact with the user's legs so that the user's legs are simultaneously in contact with the pressing component 3224 and the first fixing member 3221, so as to achieve further fixation of the user's legs. By rotatably connecting the rotating connecting mechanism 3222 with the power output end of the motion driving member 321, the motion driving members 321 of each motion mechanism 32 can respectively lift the connected connecting mechanisms to different heights, so that the relative positions of the first fixing member 3221, the second fixing member 3223 and the downward pressing component 3224 remain unchanged (the user's legs are still fixed by the first fixing member 3221, the second fixing member 3223 and the downward pressing component 3224), and the angle formed between the user's thigh and calf is less than 180 degrees, so as to achieve bending of the user's legs.

[0066] In some embodiments, see Figure 3 to Figure 4 The rotating connection mechanism 3222 includes a rotating connection member 32221, a rotating connection plate 32222 and a plurality of rotating wheels 32223.

[0067] The rotating connecting member 32221 is arranged on a side of the first fixing member 3221 close to the motion driving member 321 . The rotating connecting member 32221 has a motion accommodating space. A motion groove 322211 connected to the motion accommodating space is provided on a side of the rotating connecting member 32221 close to the motion driving member 321 .

[0068] The rotating connecting plate 32222 is movably disposed in the motion accommodating space, and the power output end of the motion driving member 321 is rotationally connected to the rotating connecting plate 32222 via the motion groove 322211 .

[0069] A plurality of rotating wheels 32223 are disposed on the rotating connecting plate 32222 and are in frictional contact with the inner wall of the movement accommodating space.

[0070] It can be understood that the rotating connection member 32221 is a shell having a motion accommodating space and a motion groove 322211 connected to the motion accommodating space. For example, the rotating connection member 32221 can be an aluminum shell, a copper shell, etc., but not limited thereto. The rotating connection plate 32222 is a plate-like structure. For example, the rotating connection plate 32222 can be an aluminum plate, a copper plate, etc., but not limited thereto. The rotating wheel 32223 is a wheel. For example, the rotating wheel 32223 can be a 360-degree free-rotating wheel, a rubber moving wheel 3113, etc., but not limited thereto.

[0071] In this way, when the power output end of the motion driver 321 is extended to drive the user's legs away from the support accommodation space, the rotating connecting plate 32222 is resisted by the power output end of the motion driver 321 and moves along the motion groove 322211 to the side of the motion accommodation space away from the user's pelvis; when the power output end of the motion driver 321 is shortened to drive the user's legs outside the support accommodation space to approach the support accommodation space, the rotating connecting plate 32222 is driven by the power output end of the motion driver 321 and moves along the motion groove 322211 to the side of the motion accommodation space close to the user's pelvis. By movably arranging the rotating connecting plate 32222 in the motion accommodation space, the user's legs can be moved without rotating the motion driver 321 along the length direction of the user's legs, so that the user's legs are close to or away from the support accommodation space, thereby enhancing the structural stability of the motion driver 321.

[0072] In some embodiments, see Figure 3 and Figure 5 A plurality of fixing holes 32211 communicating with the first fixing accommodation space are provided on both sides of the first fixing member 3221 , and the second fixing member 3223 includes a fixing plate 32231 , two movable members 32232 and an elastic member 32233 .

[0073] The fixing plate 32231 is partially located in the first fixed accommodating space, and the fixing plate 32231 has a second fixed accommodating space. Connecting holes 322311 corresponding to the fixing holes 32211 are provided on both sides of the fixing plate 32231, and movable holes 322312 connected to the second fixed accommodating space are provided at both ends of the side of the fixing plate 32231 away from the first fixing piece 3221.

[0074] The two movable parts 32232 are partially located in the second fixed accommodating space, and are movably arranged on both sides of the second fixed accommodating space relative to each other. The movable part 32232 can be partially located outside the first fixed accommodating space through the connecting hole 322311 and the fixed hole 32211, and the movable part 32232 can be partially located outside the second fixed accommodating space through the movable hole 322312.

[0075] The elastic member 32233 is located in the second fixed accommodation space and between the two movable members 32232 . Both ends of the elastic member 32233 are respectively connected to the two movable members 32232 . The elastic member 32233 is used to drive the two movable members 32232 to move away from each other.

[0076] It can be understood that the fixed plate 32231 is a plate-like structure having a second fixed accommodation space, for example, the fixed plate 32231 can be an aluminum plate, a copper plate, etc., but not limited thereto. The movable member 32232 is a block-like structure, for example, the movable member 32232 can be an aluminum block, a copper block, etc., but not limited thereto. The elastic member 32233 is a spring, for example, the elastic member 32233 can be a coil spring, a disc spring, etc., but not limited thereto.

[0077] With such arrangement, when the user's leg is placed on the accommodating portion 33, the user or doctor can continuously push the movable member 32232 through the movable hole 322312 to be located outside the second fixed accommodating space, so that the two movable members 32232 are close to each other and compress the elastic member 32233, and the two movable members 32232 are moved to the first fixed accommodating space through the connecting hole 322311 and the fixing hole 32211 to be located outside the first fixed accommodating space, and then push the fixing plate 32231 to make the fixing plate 32231 close to the first fixing member 3221, so that the user's leg is simultaneously moved by the first fixing member 3221 and the fixing plate 32233 1 to fix the user's legs; when the user's legs are simultaneously contacted by the first fixing member 3221 and the fixing plate 32231, the user or the doctor can loosen the movable member 32232 so that the portion located outside the second fixed accommodation space passes through the movable hole 322312, and the two movable members 32232 move away from each other under the elastic force of the elastic member 32233, and are partially located outside the first fixed accommodation space through the connecting hole 322311 and the fixing hole 32211, so that the position of the fixing plate 32231 is fixed with the first fixing member 3221, and further the position of the user's legs is fixed with the fixing plate 32231 and the first fixing member 3221.

[0078] The present application also provides a method for controlling a postoperative recovery training device for joint surgery for sports medicine. The postoperative recovery training device for joint surgery for sports medicine of the above embodiment is used. The method for controlling the postoperative recovery training device for joint surgery for sports medicine includes: The user is made to lie flat on the support part 10 , and the thigh and calf of at least one leg of the user are respectively fixed to at least one movement mechanism 32 , and then the user's body is fixed to the support part 10 .

[0079] Each movement mechanism 32 clamps the user's legs and moves the user's legs toward or away from the supporting and accommodating space along the first direction, so that the user's legs are higher than the placement portion 13 or lower than the placement portion 13 .

[0080] When the thigh and calf of the user are respectively clamped by at least one motion mechanism 32, the rotation mechanism 31 drives the motion mechanism 32 to rotate around the first axis, so that the thigh and calf of the user are relatively rotated outward or inward by a preset angle.

[0081] When the thigh and calf of the user are respectively clamped by at least one motion mechanism 32 and one leg of the user is placed on the placement portion 13, the rotating portion 20 drives the various motion portions 30 to rotate as a whole around the user's pelvis.

[0082] As can be seen from the above, the control method of the joint surgery postoperative recovery training device for sports medicine provided by the embodiment of the present application prevents the user from accidentally falling during the recovery training by allowing the user to lie flat on the support part 10, and fixing the thigh and calf of at least one leg of the user to at least one motion mechanism 32 respectively, and then fixing the user's body to the support part 10. Through each motion mechanism 32, the user's legs are clamped and the user's legs are respectively moved closer to or away from the support accommodating space by different distances in the first direction, so that the user's legs are higher than the placement part 13 or lower than the placement part 13, simulating the user's walking process to promote blood return to the lower limbs and relieve muscle tension and fatigue, which is beneficial to the health of the knee joint. The rotation mechanism 31 drives the motion mechanism 32 to rotate around the first axis, so that the user's thigh and calf are relatively rotated outward or inward at a preset angle to stretch the muscles and ligaments around the knee joint, and enhance the stability and flexibility of the knee joint. Through the rotating part 20, each motion part 30 is driven to rotate as a whole with the user's pelvis as the center, thereby stretching the knee joint, enhancing the strength of the muscles around the knee joint and improving the stability of the knee joint.

[0083] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
