TECHNICAL FIELD
[0001] The present application relates to the technical field of postoperative care devices, in particular to an interventional postoperative care device and a use method thereof. BACKGROUND
[0002] Interventional therapy is a technique of diagnosing and treating lesions in the body by using minimally invasive instruments such as catheters and guide wires under the guidance of medical imaging equipment (such as X-ray, ultrasound, CT, etc.). Compared with traditional surgical operation, it has the advantages of small trauma, fast recovery, and few complications, and has been widely used in clinical fields such as cardiovascular system, digestive system, respiratory system, nervous system, and tumor treatment, such as percutaneous coronary intervention (PCI), transcatheter arterial chemoembolization (TACE) for liver cancer, and embolization of cerebral aneurysm. With the continuous innovation of interventional therapy technology and the continuous expansion of its clinical application range, the number of patients receiving interventional surgery is increasing year by year, and the quality and efficiency of postoperative care have a decisive influence on the rehabilitation effect, complication rate and prognosis of patients, so the research and development of interventional postoperative care related technology and devices have become one of the focuses in the medical field.
[0003] Vital sign monitoring and body position management are the basic content of postoperative care, and for interventional surgery of the leg joint, postoperative rehabilitation training and joint support protection are the key links to determine the recovery of joint function. Postoperative patients often have joint stiffness and muscle atrophy due to pain and immobilization, so they need to use continuous passive motion (CPM) rehabilitation machines for early rehabilitation training, which can maintain joint range of motion, promote local blood circulation, and prevent tissue adhesion by simulating the physiological motion trajectory of the joint. However, in the clinical application of CPM machines, a fixed size leg is often used to fix and support the patient's leg, and the knee joint lacks precise support, which can easily cause stress concentration on the medial and lateral sides of the joint during rehabilitation exercise, increasing the risk of meniscus and ligament damage. SUMMARY
[0004] To solve the above technical problems, the present application provides an interventional postoperative care device, which comprises a base, a driving motor fixedly connected to the inner wall of the base, and a threaded rod fixedly connected to the outer wall of the driving motor shaft, and further comprises: a support mechanism fixedly connected to the inner wall of the base at the outer wall of the support mechanism, the support mechanism being used to support the patient's leg; a limiting mechanism rotatably connected to the inner wall of the support mechanism at the outer wall of the limiting mechanism, the limiting mechanism being used to limit the rotation amplitude of the patient's joint; an adjusting mechanism fixedly connected to the outer wall of the limiting mechanism at the outer wall of the adjusting mechanism, the adjusting mechanism being used to adjust the movement position of the patient's leg during rehabilitation; In use, first, the device is placed in a suitable position for nursing the patient, then the leg of the patient needing nursing is placed on the device, and then a special elastic bandage is used to fix the leg of the patient on the device with appropriate force, and then the parameters of the driving motor are adjusted according to the data provided by the doctor, and the driving motor is started to start nursing the leg of the patient. The inner wall of the base is fixedly connected with a profile, the outer wall of the profile is slidably connected with a sliding block, the inner wall of the sliding block is rotatably connected with a connecting rod, and the inner wall of the connecting rod is fixedly connected with two supporting rods.
[0005] The inner wall of the sliding block is threadedly connected with the outer wall of the threaded rod.
[0006] Preferably, the supporting mechanism comprises: The outer wall of the supporting assembly is rotatably connected with the inner wall of the supporting rod.
[0007] Preferably, the limiting mechanism comprises: The outer wall of the limiting assembly is rotatably connected with the inner wall of the supporting assembly; The outer wall of the following assembly is fixedly connected with the inner wall of the limiting assembly.
[0008] Preferably, the adjusting mechanism comprises: The outer wall of the elastic assembly is fixedly connected with the outer wall of the following assembly; The outer wall of the adjusting assembly is slidably connected with the inner wall of the elastic assembly.
[0009] Preferably, the supporting assembly comprises two supporting rods one fixedly connected with the inner wall of the two supporting rods, two supporting rods two rotatably connected with the inner wall of the two supporting rods one, and a supporting cloth one fixedly connected with the outer wall of the two supporting rods one and a supporting cloth two fixedly connected with the outer wall of the two supporting rods two. When placing the leg of the patient, first, the patient is assisted to place the thigh of the patient on the supporting cloth two and the calf on the supporting cloth one, and then the foot is fixed on the foot pedal, and at the same time, the position of the knee joint of the patient is adjusted to be located at the connection between the supporting rod one and the supporting rod two. The outer wall of the two supporting rods two is rotatably connected with the inner wall of the base.
[0010] Further, after the driving motor is started, the driving shaft of the driving motor drives the threaded rod to rotate, and the rotation of the threaded rod drives the sliding block to move, causing the sliding block to start to move away from the driving motor, and the movement of the sliding block causes the connecting rod to move, and the movement of the connecting rod also drives the supporting rod to move. When placing the patient's leg, adjust the angle between the supporting rod and the supporting rod to make the device meet the angle change required during the patient's leg movement during rehabilitation nursing. After the supporting rod moves with the connecting rod, it moves together with the connecting part of the supporting rod. The movement of the supporting rod one causes the supporting rod one and the supporting rod two to rotate relative to each other, and the other end of the supporting rod two is rotatably connected with the inner wall of the base, so that the supporting rod two rotates around the connecting part of the base, and the angle change of the supporting rod one and the supporting rod two drives the supporting cloth one and the supporting cloth two on them to change, and in turn drives the large and small legs fixed thereon to make a bending leg action, and through the reciprocating movement of the driving motor, the patient's leg makes a reciprocating bending leg movement. Preferably, the limiting assembly comprises two rotating rods rotatably connected to the inner walls of the two supporting rods, two limiting nuts threadedly connected to the outer walls of the two rotating rods, two spacers slidably connected to the outer walls of the two rotating rods, and two limiting springs sleeved on the outer walls of the two rotating rods. The outer wall of the limiting spring is fixedly connected with the outer wall of the limiting nut, and the outer wall of the end of the limiting spring away from the limiting nut is fixedly connected with the spacer.
[0011] Preferably, the follower assembly comprises a supporting plate fixedly connected to the outer walls of the two rotating rods, two sliding blocks slidably connected to the inner wall of the supporting plate, two connecting columns slidably connected to the inner walls of the two sliding blocks, and two return springs fixedly connected to the outer walls of the two connecting columns. The outer wall of the end of the two return springs away from the connecting column is fixedly connected with the outer wall of the sliding block.
[0012] Preferably, the elastic assembly comprises an articulation supporting plate fixedly connected to the outer wall of the sliding block, an elastic plate fixedly connected to the inner wall of the articulation supporting plate, and two sliding grooves formed in the outer wall of the articulation supporting plate.
[0013] When patients use this device for rehabilitation care, the joints swing to varying degrees during movement. As the device moves the patient's leg, the force on the joints is concentrated on the meniscus, cruciate ligaments, and other areas. Without proper support, this can lead to ligament sprains, meniscus wear, and potentially joint damage. Furthermore, the movement of the supported joint can cause trajectory deviation, resulting in knee varus, valgus, or anterior-posterior displacement. Over time, this can lead to uneven stress on the articular cartilage, potentially inducing joint degeneration and affecting function. Therefore, when stabilizing the patient's leg, the joint is placed on a joint support plate. The weight of the leg applies pressure to the joint support plate, causing it to move closer to the support plate. The movement of the joint support plate also moves the sliding block on it, stretching the return spring. Furthermore, when the leg is placed on the joint support plate, the elastic plate inside the plate, under the combined force of the sliding block and the leg, keeps the joint support plate firmly against the patient's leg, thus better protecting and supporting the leg during care and reducing the chance of injury. When caring for various leg types, such as X-shaped legs and O-shaped legs, the joint position may turn outward or inward during the procedure. When the surgical site is near these leg types, prolonged care can increase the risk of uneven weight distribution and bleeding, affecting postoperative recovery. In such cases, the knee's movement trajectory differs from that of normal patients, exhibiting more irregular changes. For example, in X-shaped legs, the joint may initially move closer to the knee and then further away, with the leg prone to outward turning. This causes a conflict between the device's movement trajectory and the joint's natural mechanical axis, resulting in… The device causes joint torsion, increasing the risk of ligament tears and tendon strains. When the joint position changes, pressure is applied to one side of the joint support plate, and pressure is also applied to the sliding block on that side, causing the joint support plate to tilt to one side. Under the action of the elastic plate and the sliding block on the other side, the joint support plate will continue to be pressed tightly against the leg. At the same time, when the pressure applied by the leg shifts, the joint support plate will also move with the movement of the leg joint. Under the action of the sliding block, connecting column and return spring, the joint support plate will slide along the support plate, thereby better protecting the joint. Since the joint part moves up and down along its natural mechanical axis when the device is used to care for the patient's leg, and since the thigh position at the two support cloth positions gradually moves away from the driving motor, the joint position also moves away from the driving motor during the upward movement, and further, due to the structure of the leg joint, the joint support plate will form a certain angle with the joint, so that the joint support plate will rub against the joint, and if the leg is fixed tightly, it may cause damage to the joint inside the joint support plate, at this time, since the rotating rod can rotate around the connection of the support rod two, the joint support plate can change according to the angle change of the joint, and at the same time, by adjusting the pressure of the limiting spring exerted by the limiting nut, the rotating degree of the joint support plate can be limited, and the fitting effect of the joint support plate on the joint is enhanced, and the joint care is better. Preferably, the adjusting assembly comprises a plurality of sliding limiting blocks slidingly connected at the inner walls of the two sliding grooves, and a plurality of top screws are threadedly connected at the inner walls of the plurality of sliding limiting blocks.
[0014] Since the patient's intervention surgery site may be at the joint part during the use of the device for care, it is necessary to avoid the surgery site during use to reduce the compression on the surgery site and reduce the probability of injury to the patient, at this time, the top screws on the sliding limiting blocks are loosened, so that the sliding limiting blocks can slide on the sliding grooves, and the position of the sliding limiting blocks is adjusted, so that the sliding limiting blocks can adjust the position of the counterweight, and since the position of the counterweight changes, the joint support plate will also rotate, and the opening position of the joint support plate changes to the surgery site at the joint, so that the position of the joint support plate can be adjusted within a certain range to reduce the probability of damage to the surgery site. A use method of an intervention postoperative care device, comprising the following steps, S1: Fix the leg: first place the patient's leg on the device, and fix it on the device using the binding belt; S2: Start the device: turn on the driving motor and start the rehabilitation care for the patient.
[0015] The present application has the following advantages: (1) The present application is used for rehabilitation nursing of patients, and the joint will swing in different degrees during the movement of the patient, and the stress of the joint is concentrated on the meniscus and the cross ligament during the movement of the device driven by the patient's leg, if the joint is not properly supported, the ligament may be injured, the meniscus may be worn, and the joint may be damaged, and the trajectory of the joint supported by the support plate may be offset during the movement, the knee may be turned in, turned out or displaced forward and backward, and the uneven stress on the joint cartilage may cause joint degeneration and affect the function, at this time, the joint is placed on the joint support plate when the patient's leg is fixed, and the joint support plate is close to the support plate due to the weight of the leg, and the movement of the joint support plate also drives the sliding block on the joint support plate to move, and the reset spring is stretched, further, the elastic plate inside the joint support plate is close to the patient's leg under the action of the sliding block and the leg force when the leg is placed on the joint support plate, so that the patient's leg is better protected during nursing, and the probability of injury is reduced; (2) The present application is used for rehabilitation nursing of patients, and the joint will swing in different degrees during the movement of the patient, and the stress of the joint is concentrated on the meniscus and the cross ligament during the movement of the device driven by the patient's leg, if the joint is not properly supported, the ligament may be injured, the meniscus may be worn, and the joint may be damaged, and the trajectory of the joint supported by the support plate may be offset during the movement, the knee may be turned in, turned out or displaced forward and backward, and the uneven stress on the joint cartilage may cause joint degeneration and affect the function, at this time, the joint is placed on the joint support plate when the patient's leg is fixed, and the joint support plate is close to the support plate due to the weight of the leg, and the movement of the joint support plate also drives the sliding block on the joint support plate to move, and the reset spring is stretched, further, the elastic plate inside the joint support plate is close to the patient's leg under the action of the sliding block and the leg force when the leg is placed on the joint support plate, so that the patient's leg is better protected during nursing, and the probability of injury is reduced; (3) When the device is used to care for various leg shapes, such as X-shaped legs and O-shaped legs, the joint position may appear to be outwardly or inwardly tilted during the care process. When the surgical site is located near the joint position, the uneven stress on the leg during the long-term care process may increase the risk of bleeding, affecting the patient's postoperative recovery. At this time, the movement trajectory of the knee joint of such patients is different from that of normal patients, and the trajectory changes irregularly. For example, for X-shaped legs, the joint position first approaches and then moves away, and the leg is prone to an outward tilt, which may cause the movement trajectory of the device to conflict with the natural mechanical axis of the joint, causing the device to twist the joint and increasing the risk of ligament tears and tendon injuries. At this time, when the joint position changes, pressure is exerted on one side of the joint support plate, and pressure is also exerted on the sliding block on the same side, causing the joint support plate to tilt toward one side. Under the action of the elastic plate and the sliding block on the other side, the joint support plate is continuously pressed against the leg. At the same time, due to the shift in pressure exerted by the leg, the joint support plate will also change along with the changes in the joint of the leg. Under the action of the sliding block, the connecting column, and the return spring, the joint support plate will slide along the support plate, thereby better protecting the joint. (4) When the device is used to care for the patient's leg, the joint position will move up and down along its natural mechanical axis. At the same time, the thigh position away from the driving motor will gradually move away from the driving motor during the upward movement of the joint position. Further, due to the structure of the leg joint, the joint support plate will form a certain angle with the joint, causing the joint support plate to press against the joint. If the leg is fixed tightly, it may cause damage to the joint inside the joint support plate. At this time, since the rotating rod can rotate around the connection of the support rod two, the joint support plate can change according to the angle change of the joint. At the same time, by adjusting the pressure exerted by the limiting nut on the limiting spring, the rotating degree of the joint support plate can be limited, enhancing the fitting effect of the joint support plate on the joint and better protecting the joint.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] Example 1, please refer to Figure 1 - Figure 6 This invention relates to a post-interventional nursing device, comprising a base 13, a drive motor 14 fixedly connected to the inner wall of the base 13, and a threaded rod 15 fixedly connected to the outer wall of the drive shaft of the drive motor 14, and further comprising: Support mechanism 1, the outer wall of support mechanism 1 is fixedly connected to the inner wall of base 13, and support mechanism 1 is used to support the patient's legs; The limiting mechanism 2 is rotatably connected to the inner wall of the supporting mechanism 1 at its outer wall. The limiting mechanism 2 is used to limit the range of rotation at the patient's joint. Adjustment mechanism 3 is fixedly connected to the outer wall of restriction mechanism 2. Adjustment mechanism 3 is used to adjust the movement position of the patient's leg during rehabilitation. When using it, first place the device in a suitable position for the patient, then place the leg that needs care on the device, and then use a special elastic bandage to apply appropriate force to fix the patient's leg on the device. After that, adjust the parameters of the drive motor 14 according to the data provided by the doctor, start the drive motor 14, and let it begin to care for the patient's leg. A profile 111 is fixedly connected to the inner wall of the base 13. A slider 112 is slidably connected to the outer wall of the profile 111. A connecting rod 113 is rotatably connected to the inner wall of the slider 112. Two support rods 114 are fixedly connected to the inner wall of the connecting rod 113. A fixing rod 115 is rotatably connected to the inner wall of the two support rods 114. A foot pedal 116 is fixedly connected to the outer wall of the fixing rod 115.
[0021] The inner wall of slider 112 is threaded to the outer wall of threaded rod 15.
[0022] Supporting mechanism 1 includes: The outer wall of the support assembly 12 is rotatably connected to the inner wall of the support rod 114.
[0023] Restricted agency 2 includes: The outer wall of the limiting component 21 is rotatably connected to the inner wall of the supporting component 12; Follower component 22 is fixedly connected to the inner wall of restraint component 21 at its outer wall.
[0024] Adjustment mechanism 3 includes: The elastic component 31 is fixedly connected to the outer wall of the follower component 22 at its outer wall. Adjustment component 32 is slidably connected to the inner wall of elastic component 31 at its outer wall.
[0025] The support assembly 12 includes two support rods 121 fixedly connected to the inner walls of the two support rods 114, two support rods 122 rotatably connected to the inner walls of the two support rods 121, a support cloth 123 fixedly connected to the outer walls of the two support rods 121, and a support cloth 124 fixedly connected to the outer walls of the two support rods 122. When placing the patient's legs, first assist the patient to place their thigh on support cloth 2 124 and their lower leg on support cloth 1 123. Then fix the foot on foot pedal 116. At the same time, adjust the position of the patient's knee joint so that it is located at the connection between support rod 1 121 and support rod 2 122. The outer walls of the two support rods 122 are rotatably connected to the inner wall of the base 13.
[0026] Furthermore, after the drive motor 14 is started, the drive shaft of the drive motor 14 drives the threaded rod 15 to rotate. The rotation of the threaded rod 15 will drive the slider 112 to move, causing the slider 112 to move away from the drive motor 14. The movement of the slider 112 will cause the connecting rod 113 to move as well. The movement of the connecting rod 113 will also drive the support rod 114 to move. When placing the patient's leg, the angle between the support rod 121 and the support rod 114 is adjusted so that when the device is running, the angle of the patient's leg movement meets the angle change required for rehabilitation care. After the support rod 114 moves with the connecting rod 113, it will drive the connection point with the support rod 121 to move together. The movement of the support rod 121 will cause the support rod 121 and the support rod 122 to rotate relative to each other. The other end of the support rod 122 is rotatably connected to the inner wall of the base 13, so that the support rod 122 will rotate around the connection point with the base 13. The change in the angle of the support rod 121 and the support rod 122 will drive the support cloth 123 and the support cloth 124 on them to change together, thereby driving the legs fixed on them to perform flexion and extension movements. Through the reciprocating motion of the drive motor 14, the patient's legs will perform reciprocating flexion and extension movements. The limiting component 21 includes two rotating rods 211 rotatably connected to the inner wall of the two support rods 121, two limiting nuts 212 threadedly connected to the outer wall of the two rotating rods 211, two washers 213 slidably connected to the outer wall of the two rotating rods 211, and two limiting springs 214 sleeved on the outer wall of the two rotating rods 211. The outer wall of the limiting spring 214 is fixedly connected to the outer wall of the limiting nut 212, and the outer wall of the end of the limiting spring 214 away from the limiting nut 212 is fixedly connected to the washer 213.
[0027] The follower assembly 22 includes a support plate 221 fixedly connected to the outer wall of the two rotating rods 211, two sliding blocks 222 slidably connected to the inner wall of the support plate 221, two connecting posts 223 slidably connected to the inner wall of the two sliding blocks 222, and two return springs 224 fixedly connected to the outer wall of the two connecting posts 223. The outer wall of the two return springs 224 away from the connecting post 223 is fixedly connected to the outer wall of the sliding block 222.
[0028] Example 2, please refer to Figure 2 - Figure 9 The present invention is a post-interventional nursing device. Based on the first embodiment, the elastic component 31 includes a joint support plate 311 fixedly connected to the outer wall of the sliding block 222, an elastic plate 312 fixedly connected to the inner wall of the joint support plate 311, and two sliding grooves 313 formed on the outer wall of the joint support plate 311.
[0029] When patients use this device for rehabilitation care, the joints will swing to varying degrees during movement. As the device moves the patient's leg, the stress on the joints is concentrated on the meniscus and cruciate ligaments. Without proper support, this can lead to ligament sprains, meniscus wear, and potentially joint damage. Furthermore, the joint supported by the device may deviate from its trajectory during movement, causing the knee to varus, valgus, or anteroposterior displacement. Over time, this can lead to uneven stress on the articular cartilage, potentially inducing joint degeneration and affecting function. Therefore, when stabilizing the patient's leg, placing the joints on the joint support... On the support plate 311, the weight of the leg will exert pressure on the joint support plate 311, causing the joint support plate 311 to move closer to the support plate 221. At the same time, the movement of the joint support plate 311 will also drive the sliding block 222 on it to move together, and stretch the return spring 224. Furthermore, when the leg is placed on the joint support plate 311, the elastic plate 312 inside the joint support plate 311 will make the joint support plate 311 fit tightly against the patient's leg under the action of the sliding block 222 and the force of the leg, thereby better protecting and supporting the patient's leg during care and reducing the chance of injury. When caring for various leg types, such as X-shaped legs and O-shaped legs, the joint position may turn outward or inward during the procedure. When the surgical site is near these leg types, prolonged care can increase the risk of uneven weight distribution and bleeding, affecting postoperative recovery. In these cases, the knee's movement trajectory differs from that of normal patients, exhibiting more irregular changes. For example, in X-shaped legs, the joint initially moves closer and then further away, and the leg is prone to outward turning. This causes the device's movement trajectory to conflict with the joint's natural mechanical axis, leading to joint twisting and increasing the risk of ligament and tendon tears. The risk of strain is that when the joint position changes, pressure is applied to one side of the joint support plate 311, and pressure is also applied to the sliding block 222 on this side, causing the joint support plate 311 to tilt to one side. Under the action of the elastic plate 312 and the sliding block 222 on the other side, the joint support plate 311 will continue to be pressed against the leg. At the same time, when the pressure applied to the leg shifts, the joint support plate 311 will also move with the movement of the leg joint. Under the action of the sliding block 222, the connecting column 223 and the return spring 224, the joint support plate 311 will slide along the support plate 221, thereby better protecting the joint. When the device cares for the patient's leg, the joint moves up and down along its natural mechanical axis. Simultaneously, as the thigh position at support cloth 2 124 gradually moves away from drive motor 14, the joint position also moves away from drive motor 14 during the upward movement. Furthermore, due to the structure of the leg joint, the joint support plate 311 will be at a certain angle to the joint, causing it to press against the joint. If the leg is fixed too tightly, the joint support plate 311 may cause damage to the joint's interior. At this point, since the rotating rod 211 can rotate around the connection point of support rod 2 122, the joint support plate 311 can change according to the angle of the joint. At the same time, by adjusting the pressure applied to the limiting spring 214 by the limiting nut 212, the rotational force of the joint support plate 311 can be limited, enhancing the fit of the joint support plate 311 to the joint and providing better joint care. The adjustment assembly 32 includes a plurality of sliding limit blocks 321 slidably connected to the inner walls of the two slide grooves 313, a plurality of set screws 322 threadedly connected to the inner walls of the plurality of sliding limit blocks 321, and a plurality of counterweight blocks 323 slidably connected to the inner walls of the two slide grooves 313.
[0030] Since the patient's surgical site may be at the joint when using the device for care, it is necessary to avoid the surgical site during use to reduce pressure on the surgical site and reduce the probability of injury to the patient. At this time, the set screw 322 on the sliding limit block 321 is released so that the sliding limit block 321 can slide on the slide groove 313. At the same time, the position of the sliding limit block 321 is adjusted so that the position of the counterweight block 323 can be adjusted. Due to the change in the position of the counterweight block 323, the joint support plate 311 will also rotate, and the opening position of the joint support plate 311 will change to the surgical position at the joint. Thus, the position of the joint support plate 311 can be adjusted within a certain range to reduce the probability of damage to the surgical site. A method of using a post-interventional care device includes the following steps: S1: Leg fixation: First, place the patient's leg on the device and secure it to the device with straps; S2: Start device: Turn on the drive motor 14 to begin rehabilitation care for the patient.
[0031] One specific application of this embodiment is as follows: When using it, first place the device in a suitable position for caring for the patient, then place the leg that the patient needs to be cared for on the device, and then use a special elastic bandage to apply appropriate force to fix the patient's leg on the device. After that, adjust the parameters of the drive motor 14 according to the data provided by the doctor, start the drive motor 14, and make it start to care for the patient's leg. When placing the patient's legs, first assist the patient to place their thigh on support cloth 2 124 and their lower leg on support cloth 1 123. Then fix the foot on foot pedal 116. At the same time, adjust the position of the patient's knee joint so that it is located at the connection between support rod 1 121 and support rod 2 122. Furthermore, after the drive motor 14 is started, the drive shaft of the drive motor 14 drives the threaded rod 15 to rotate. The rotation of the threaded rod 15 will drive the slider 112 to move, causing the slider 112 to move away from the drive motor 14. The movement of the slider 112 will cause the connecting rod 113 to move as well. The movement of the connecting rod 113 will also drive the support rod 114 to move. When placing the patient's leg, the angle between the support rod 121 and the support rod 114 is adjusted so that when the device is running, the angle of the patient's leg movement meets the angle change required for rehabilitation care. After the support rod 114 moves with the connecting rod 113, it will drive the connection point with the support rod 121 to move together. The movement of the support rod 121 will cause the support rod 121 and the support rod 122 to rotate relative to each other. The other end of the support rod 122 is rotatably connected to the inner wall of the base 13, so that the support rod 122 will rotate around the connection point with the base 13. The change in the angle of the support rod 121 and the support rod 122 will drive the support cloth 123 and the support cloth 124 on them to change together, thereby driving the legs fixed on them to perform flexion and extension movements. Through the reciprocating motion of the drive motor 14, the patient's legs will perform reciprocating flexion and extension movements. When patients use this device for rehabilitation care, the joints will swing to varying degrees during movement. As the device moves the patient's leg, the stress on the joints is concentrated on the meniscus and cruciate ligaments. Without proper support, this can lead to ligament sprains, meniscus wear, and potentially joint damage. Furthermore, the joint supported by the device may deviate from its trajectory during movement, causing the knee to varus, valgus, or anteroposterior displacement. Over time, this can lead to uneven stress on the articular cartilage, potentially inducing joint degeneration and affecting function. Therefore, when stabilizing the patient's leg, placing the joints on the joint support... On the support plate 311, the weight of the leg will exert pressure on the joint support plate 311, causing the joint support plate 311 to move closer to the support plate 221. At the same time, the movement of the joint support plate 311 will also drive the sliding block 222 on it to move together, and stretch the return spring 224. Furthermore, when the leg is placed on the joint support plate 311, the elastic plate 312 inside the joint support plate 311 will make the joint support plate 311 fit tightly against the patient's leg under the action of the sliding block 222 and the force of the leg, thereby better protecting and supporting the patient's leg during care and reducing the chance of injury. Since the patient's surgical site may be at the joint when using the device for care, it is necessary to avoid the surgical site during use to reduce pressure on the surgical site and reduce the probability of injury to the patient. At this time, the set screw 322 on the sliding limit block 321 is released so that the sliding limit block 321 can slide on the slide groove 313. At the same time, the position of the sliding limit block 321 is adjusted so that the position of the counterweight block 323 can be adjusted. Due to the change in the position of the counterweight block 323, the joint support plate 311 will also rotate, and the opening position of the joint support plate 311 will change to the surgical position at the joint. Thus, the position of the joint support plate 311 can be adjusted within a certain range to reduce the probability of damage to the surgical site. When caring for various leg types, such as X-shaped legs and O-shaped legs, the joint position may turn outward or inward during the procedure. When the surgical site is near these leg types, prolonged care can increase the risk of uneven weight distribution and bleeding, affecting postoperative recovery. In these cases, the knee's movement trajectory differs from that of normal patients, exhibiting more irregular changes. For example, in X-shaped legs, the joint initially moves closer and then further away, and the leg is prone to outward turning. This causes the device's movement trajectory to conflict with the joint's natural mechanical axis, leading to joint twisting and increasing the risk of ligament and tendon tears. The risk of strain is that when the joint position changes, pressure is applied to one side of the joint support plate 311, and pressure is also applied to the sliding block 222 on this side, causing the joint support plate 311 to tilt to one side. Under the action of the elastic plate 312 and the sliding block 222 on the other side, the joint support plate 311 will continue to be pressed against the leg. At the same time, when the pressure applied to the leg shifts, the joint support plate 311 will also move with the movement of the leg joint. Under the action of the sliding block 222, the connecting column 223 and the return spring 224, the joint support plate 311 will slide along the support plate 221, thereby better protecting the joint. When the device cares for the patient's leg, the joint moves up and down along its natural mechanical axis. Simultaneously, as the thigh position at support fabric 124 gradually moves away from drive motor 14, the joint position also moves away from drive motor 14 during the upward movement. Furthermore, due to the structure of the leg joint, the joint support plate 311 will be at a certain angle to the joint, causing it to press against the joint. If the leg is fixed too tightly, the joint support plate 311 may cause damage to the joint's interior. At this point, since the rotating rod 211 can rotate around the connection point of support rod 122, the joint support plate 311 can change according to the angle of the joint. At the same time, by adjusting the pressure applied to the limiting spring 214 by the limiting nut 212, the rotational force of the joint support plate 311 can be limited, enhancing the fit of the joint support plate 311 to the joint and providing better joint care.
