Description

Technical Field

[0001] The present invention relates to the technical field of joint rehabilitation, and more specifically, to an orthopedic leg joint rehabilitation mobilizer. Background Art

[0002] The leg joints mainly include ankle joints, hip joints and knee joints. Different joints have different structures and characteristics. They are involved in the joint activities of various parts of the leg. Factors such as cold, long-term exercise, strain, osteoarthritis, rheumatoid arthritis, etc. can cause leg joint pain. After surgery or drug treatment, leg joint pain requires the use of leg joint rehabilitation devices to rehabilitate the leg joints and improve the recovery effect of the leg joints.

[0003] However, the existing leg joint rehabilitation mobilizers have the following shortcomings in assisting the patient's leg joints in rehabilitation: the structure of the joint rehabilitation mobilizer is relatively simple and fixed, and the joint rehabilitation mobilizer is prone to jamming and damage to parts during long-term rehabilitation activities, making it difficult to disassemble, repair and replace, and the corresponding joint rehabilitation mobilizer can only perform rehabilitation activities on the corresponding joints of the leg. The leg includes three joints: ankle joint, hip joint and knee joint, so three different joint rehabilitation mobilizers are needed to perform rehabilitation activities, reducing the effect of the leg joint rehabilitation mobilizer in performing comprehensive rehabilitation activities on the leg joints at one time. Summary of the invention

[0004] The technical solution adopted by the present invention to achieve the technical purpose is: an orthopedic leg joint rehabilitation mobilizer, whose structure includes a support base, a backrest, a sponge pad, a seat, a lifter, and a rehabilitation mechanism. The rear side of the upper end surface of the support base is welded to the lower end of the backrest, and a sponge pad is fittedly installed at the front end of the backrest. The seat is located in front of the backrest, and the bottom of the seat is welded to the top of the lifter. The lower end of the lifter is installed on the upper end surface of the support base, and the rehabilitation mechanism is installed at the front end of the support base. The rehabilitation mechanism includes an abduction mechanism and a movable mechanism. The rear end of the abduction mechanism is slidably installed inside the front end of the support base, and the front end of the abduction mechanism is engaged and connected with the rear end of the movable mechanism. Two of the abduction mechanism and the movable mechanism are provided, and are symmetrically installed at the front end of the support base.

[0005] As a further improvement of the present invention, the outward expansion mechanism includes a sliding block, a pulley, an elastic component, a connecting shell, and a clamping mechanism. The sliding block is slidably installed inside the front end of the supporting base plate, and a pulley is installed in the middle of the sliding block. The pulley is slidably connected to the front end of the supporting base plate. The right side of the sliding block is fixed to the left end of the elastic component, and the elastic component is fixedly installed inside the front end of the supporting base plate. A connecting shell is fixedly installed at the front end of the sliding block, and a clamping mechanism is provided inside the front end of the connecting shell. The connecting shell is clamped and connected to the rear end of the movable mechanism through the clamping mechanism. The elastic component is composed of a round tube sleeve, a spring, and an extrusion rod, and elastic force is applied to the extrusion rod by the spring inside the round tube sleeve.

[0006] As a further improvement of the present invention, the clamping mechanism includes a knob, a sliding rod, a threaded rod, and a clamping block. The knob is installed on the outer surface of the connecting shell, and the knob is fixed to the right end of the threaded rod. The threaded rod is passed through the interior of the sliding rod with a clearance fit and is threadedly connected. The front end of the sliding rod is welded to the rear end of the clamping block, and the clamping block is located on the front surface of the connecting shell. The clamping block is snap-fitted and installed inside the rear end of the movable mechanism. Two of the sliding rod, threaded rod, and clamping block are each provided and are installed symmetrically on the left and right. The threads on the two threaded rods are reverse threads.

[0007] As a further improvement of the present invention, the movable mechanism includes a connecting base, a footrest, a spring rod, a lifting plate, a resistance piece, and a running mechanism. The connecting base is fixedly mounted on the bottom of the footrest, and the connecting base is mounted on the upper end of the running mechanism. A spring rod is mounted in the middle of the edge of the footrest, and the lower end of the spring rod is clearance-fitted and penetrates the edge of the lifting plate. A resistance piece is provided at the bottom of the lifting plate, and the resistance piece is located in the middle of the footrest. The rear end of the running mechanism is clamped and connected with the clamping block. The front end of the footrest is in an arc-wrapped state, and a spring rod is mounted on both side edges of the middle of the footrest. Vertical elastic force is applied to both sides of the lifting plate through the spring rods on both sides. The bottom of the resistance piece is an inclined arc structure, and the inclined arc structures of the two resistance pieces on the two movable mechanisms are symmetrical on the left and right, which is more consistent with the instep of the human foot.

[0008] As a further improvement of the present invention, the operating mechanism includes a running base plate, a ball bearing, a snap-fit ​​groove, a propulsion block, an elastic rod, and a rotating mechanism. A ball bearing is provided at the bottom of the running base plate, and a snap-fit ​​groove is installed at the rear end of the running base plate. The running base plate is snap-fitted with the clamping block through the snap-fitting groove at the rear end. The propulsion block is slidably installed inside the upper end of the running base plate. The rear end of the elastic rod is clearance-fitted and penetrates the propulsion block, and the elastic rod is fixedly installed at the middle end of the running base plate. A rotating mechanism is installed on the top of the propulsion block, and the rotating mechanism is snap-fitted inside the lower end of the connecting base. Fifteen ball bearings are provided and distributed in a matrix at the bottom of the running base plate. The elastic rod is installed at a front-to-back horizontal angle at the center position inside the running base plate, and the elastic rod is at a vertical angle to the propulsion block.

[0009] As a further improvement of the present invention, the rotating mechanism includes a chassis, a center groove, a guide groove, a rotating disk, a center ball, and a sliding ball. The bottom of the chassis is fixedly installed on the top end face of the thrust block, and a center groove is provided at the middle end inside the chassis. The guide groove is embedded in the upper end of the chassis. The rotating disk is located above the chassis, and a center ball is provided at the middle end of the bottom of the rotating disk. The center ball is installed in the center groove with a clearance fit. The rotating disk is clamped and installed in the lower end of the connecting base. The sliding ball is arranged at the bottom of the rotating disk, and the lower end of the sliding ball is slidably connected to the inner wall of the guide groove inside the upper end of the chassis. The interior of the chassis is made of rubber material, so that the center ball can be elastically squeezed into the center groove, thereby enabling fixed-axis installation between the chassis and the rotating disk, and fixed-axis rotation is performed in the center groove through the center ball.

[0010] The beneficial effects of the present invention are:

[0011] 1. After the patient's foot is placed inside the upper end of the movable mechanism, the patient's two thighs are used to move outward, which pushes the movable mechanism to move, and the connecting shell at the rear end of the movable mechanism drives the sliding block to move inside the front end of the supporting base plate. At the same time, the spring inside the round tube sleeve on the elastic component applies elastic force to the extrusion rod, so that the elastic component applies elastic resistance to the sliding of the sliding block, and applies a certain elastic resistance to the lateral sliding of the movable mechanism, thereby improving the effect of the patient's hip joint rehabilitation activity training;

[0012] 2. After the rehabilitation activity is completed, the two threaded rods can be driven to rotate synchronously by turning the knob, and the sliding rods on both sides can be driven to drive the two clamping blocks to slide in the opposite direction. When the two "L"-shaped clamping blocks slide in the middle, the two clamping blocks can be removed from the rear end of the movable mechanism, making it easier to disassemble and repair the movable mechanism from the joint rehabilitation mobilizer;

[0013] 3. When the sole of the patient's foot is placed inside the foot rest, the lifting plate is pulled upward to drive the resistance piece to move upward. After the sole of the foot is placed, the lifting plate is released. At this time, the lifting plate is applied with a reset elastic force through the spring rods on both sides, so that the lifting plate drives the resistance piece to reset and descend. At this time, the resistance piece is in contact with the patient's instep, and the inclined arc structure of the two resistance pieces on the two foot rests is symmetrical on the left and right, which is consistent with the instep of the human body. The resistance pieces on both sides can fit on the instep of the patient for resistance and fixation, which improves the comfort and ensures that the sole of the patient's foot will not fall off from the foot rest when the patient's foot is placed inside the foot rest for joint activities;

[0014] 4. The patient's calf exerts force to push the footrest forward, and the propulsion block at the bottom of the footrest moves synchronously. At this time, the elastic rod can apply a forward and backward sliding guide elastic force to the propulsion block inside the running bottom plate to assist the patient's knee joint in rehabilitation training;

[0015] 5. While performing knee joint rehabilitation activities, the patient can rotate the sole of the foot to drive the footrest to rotate. The center ball rotates on a fixed axis inside the center groove, and the sliding ball assists in sliding on the inner wall of the guide groove inside the upper end of the chassis, thereby improving the smoothness of the rotation of the rotating disk on the upper end of the chassis, so that the footrest on the upper end of the rotating disk can rotate on a fixed axis to assist the patient's ankle joint in rehabilitation activities. The joint rehabilitation mobilizer can simultaneously perform rehabilitation activities on the patient's ankle, hip and knee joints, thereby improving the effect of comprehensive rehabilitation activities on the leg joints.

DETAILED DESCRIPTION

[0026] The present invention is further described below in conjunction with the accompanying drawings:

[0027] Embodiment 1:

[0028] As attached Figure 1 To Attachment Figure 4 As shown:

[0029] The present invention discloses an orthopedic leg joint rehabilitation mobilizer, which comprises a support base plate D, a backrest plate C, a sponge pad K, a seat plate Z, a lifter S, and a rehabilitation mechanism H. The rear side of the upper end surface of the support base plate D is welded to the lower end of the backrest plate C, and the sponge pad K is fitted and installed at the front end of the backrest plate C. The seat plate Z is located in front of the backrest plate C, and the bottom of the seat plate Z is welded to the top of the lifter S. The lower end of the lifter S is installed on the upper end surface of the support base plate D. The rehabilitation mechanism H is installed at the front end of the support base plate D. The rehabilitation mechanism H comprises an abduction mechanism h6 and an active mechanism h1. The rear end of the abduction mechanism h6 is slidably installed inside the front end of the support base plate D, and the front end of the abduction mechanism h6 is engaged and connected with the rear end of the active mechanism h1.

[0030] There are two abduction mechanisms h6 and movable mechanisms h1, and they are installed symmetrically at the front end of the support base D. During rehabilitation training, the patient's feet are placed on the movable mechanisms h1 on both sides. The abduction mechanisms h6 on both sides assist the movable mechanisms h1 on both sides to slide horizontally left and right, so that the patient's legs can move left and right and unfold, assisting the patient's hip joint in rehabilitation training.

[0031] The extension mechanism h6 includes a sliding block h66, a pulley h64, an elastic component h67, a connecting shell h69, and a clamping mechanism h61. The sliding block h66 is slidably installed inside the front end of the supporting base plate D, and a pulley h64 is installed in the middle of the sliding block h66. The pulley h64 is slidably connected to the front end of the supporting base plate D. The right side of the sliding block h66 is fixed to the left end of the elastic component h67, and the elastic component h67 is fixedly installed inside the front end of the supporting base plate D. The front end of the sliding block h66 is fixedly installed with a connecting shell h69, and a clamping mechanism h61 is provided inside the front end of the connecting shell h69. The connecting shell h69 is connected to the rear end of the movable mechanism h1 by clamping through the clamping mechanism h61.

[0032] The elastic component h67 is composed of a circular tube sleeve, a spring and an extrusion rod. The spring inside the circular tube sleeve applies elastic force to the extrusion rod, so that the elastic component h67 applies elastic resistance to the sliding of the sliding block h66 and applies a certain elastic resistance to the lateral sliding of the movable mechanism h1, thereby improving the effect of the patient's hip joint rehabilitation activity training.

[0033] The clamping mechanism h61 includes a knob 1n, a sliding rod 1k, a threaded rod 1w, and a clamping block 1j. The knob 1n is installed on the outer surface of the connecting shell h69, and the knob 1n is fixed to the right end of the threaded rod 1w. The threaded rod 1w is passed through the inside of the sliding rod 1k by a clearance fit and is threadedly connected. The front end of the sliding rod 1k is welded to the rear end of the clamping block 1j, and the clamping block 1j is located on the front surface of the connecting shell h69. The clamping block 1j is clamped and installed inside the rear end of the movable mechanism h1.

[0034] The sliding rod 1k, threaded rod 1w and clamping block 1j are each provided with two and are installed symmetrically on the left and right. The threads on the two threaded rods 1w are reverse threads. By turning the knob 1n, the two threaded rods 1w can be driven to rotate synchronously, and the sliding rods 1k on both sides are driven to drive the two clamping blocks 1j to slide in the opposite direction. The two "L"-shaped clamping blocks 1j can be firmly engaged and installed inside the rear end of the movable mechanism h1 by sliding to the outermost side. When the two clamping blocks 1j move to the middle, they can be removed from the rear end of the movable mechanism h1, which is convenient for disassembly and maintenance of the movable mechanism h1.

[0035] The specific usage and function of this embodiment are as follows:

[0036] In the present invention, when performing leg joint rehabilitation, the patient sits on the seat board Z with his back resting on the sponge pad K at the front end of the backrest board C. The lifter S is started and adjusted according to the patient's height to adjust the height of the seat board Z so that after the patient sits on the seat board Z, the patient's feet can be placed inside the upper end of the movable mechanism h1. After the patient's soles are placed inside the upper end of the movable mechanism h1, the patient's two thighs are used to move outward, and then the movable mechanism h1 is pushed to move, and the connecting shell h69 at the rear end of the movable mechanism h1 drives the sliding block h66 to move inside the front end of the supporting bottom plate D. With the assistance of the sliding of the pulley h64, the smoothness of the sliding of the sliding block h66 is improved to avoid the occurrence of At the same time, the spring inside the round tube sleeve on the elastic component h67 applies elastic force to the extrusion rod, so that the elastic component h67 applies elastic resistance to the sliding of the sliding block h66, and applies a certain elastic resistance to the lateral sliding of the movable mechanism h1, thereby improving the effect of the patient's hip joint rehabilitation training. After the rehabilitation activity is completed, the two threaded rods 1w can be driven to rotate synchronously by turning the knob 1n, and the sliding rods 1k on both sides are driven to drive the two clamping blocks 1j to slide in the opposite direction. When the two "L"-shaped clamping blocks 1j slide in the middle, the two clamping blocks 1j can be moved out from the rear end of the movable mechanism h1, which is convenient for disassembly and maintenance of the movable mechanism h1 from the joint rehabilitation mobilizer.

[0037] Embodiment 2:

[0038] As attached Figure 5 To Attachment Fig. 9 As shown:

[0039] The movable mechanism h1 includes a connecting base h17, a footrest h15, a spring rod h19, a lifting plate h13, a contact piece h18, and a running mechanism h12. The connecting base h17 is fixedly mounted on the bottom of the footrest h15, and the connecting base h17 is mounted on the upper end of the running mechanism h12. A spring rod h19 is mounted on the middle of the edge of the footrest h15, and the lower end of the spring rod h19 is fitted through the inside of the edge of the lifting plate h13 with a clearance fit. A contact piece h18 is provided at the bottom of the lifting plate h13, and the contact piece h18 is located in the middle of the footrest h15.

[0040] The front end of the footrest h15 is in an arc-wrapped state, and a spring rod h19 is installed on both sides of the edge of the middle part of the footrest h15. The spring rods h19 on both sides apply vertical elastic force to both sides of the lifting plate h13, so that the lifting plate h13 can be elastically lifted and lowered in the middle part of the footrest h15, which is conducive to the contact and fixation of the instep of the patient placed on the footrest h15. The bottom of the contact piece h18 is an inclined arc structure, and the inclined arc structures of the two contact pieces h18 on the two movable mechanisms h1 are symmetrical on the left and right, which are more consistent with the instep of the human body. The contact pieces h18 on both sides can fit on the instep of the patient for contact and fixation, which improves the comfort while ensuring that the sole of the patient's foot will not fall off from the inside of the footrest h15 when the joint is placed inside the footrest h15 for joint movement.

A rotating mechanism 2x is installed on the top of the propulsion block 2k, and the rotating mechanism 2x is snap-fitted inside the lower end of the connecting base h17.

[0042] There are fifteen balls 2g, which are distributed in a matrix at the bottom of the running base plate 2d. The balls 2g assist in sliding at the bottom of the running base plate 2d to improve the smoothness of sliding of the running base plate 2d on the floor. The elastic rod 2t is installed at a front-to-back horizontal angle at the center position inside the running base plate 2d, and the elastic rod 2t is at a vertical angle to the propulsion block 2k. The elastic rod 2t can apply a front-to-back sliding guide elastic force to the propulsion block 2k inside the running base plate 2d, so that the patient's foot can be placed on the foot rest h15 to move forward and backward, thereby assisting the patient's knee joint in rehabilitation activity training.

[0043] Wherein, the rotating mechanism 2x includes a chassis x7, a center groove x1, a guide groove x3, a rotating disk x4, a center ball x9, and a sliding ball x6. The bottom of the chassis x7 is fixedly installed on the top end surface of the propulsion block 2k, and a center groove x1 is provided at the middle end inside the chassis x7. The guide groove x3 is embedded in the upper end of the chassis x7.

The sliding ball x6 is provided at the bottom of the rotating disk x4, and the lower end of the sliding ball x6 is slidably connected to the inner wall of the guide groove x3 inside the upper end of the chassis x7.

[0044] The interior of the chassis x7 is made of rubber material, so that the center ball x9 can be elastically squeezed into the center groove x1, so that the chassis x7 and the rotating disk x4 can be installed with a fixed axis, and the center ball x9 can rotate on a fixed axis inside the center groove x1, and cooperate with the sliding ball x6 to assist in sliding on the inner wall of the guide groove x3 inside the upper end of the chassis x7, thereby improving the smoothness of the rotation of the rotating disk x4 on the upper end of the chassis x7, so that the foot rest h15 on the upper end of the rotating disk x4 can rotate on a fixed axis to assist the patient's ankle joint in rehabilitation activities.

[0045] The specific usage and function of this embodiment are as follows:

[0046] In the present invention, when the sole of the patient's foot is placed in the footrest h15, the lifting plate h13 is pulled upward to drive the resistance piece h18 to move upward. After the sole of the foot is placed, the lifting plate h13 is released, and at this time, the lifting plate h13 is applied with a reset elastic force through the spring rods h19 on both sides, so that the lifting plate h13 drives the resistance piece h18 to reset and descend. At this time, the resistance piece h18 is in contact with the patient's instep, and the two resistance pieces h18 on the two footrests h15 are inclined arc-shaped structures that are symmetrical on the left and right and are relatively consistent with the instep of the human body. The resistance pieces h18 on both sides can fit on the instep of the patient for resistance and fixation, thereby improving the comfort and ensuring that the sole of the patient's foot will not fall off from the footrest h15 when the patient's foot is placed in the footrest h15 for joint movement. After the patient's foot is fixed, the patient's calf is used to apply force to push the footrest h15 forward, and the propulsion block 2k at the bottom of the footrest h15 moves synchronously. At this time, the elastic rod 2t can be used to push the propulsion block 2 k applies forward and backward sliding guide elastic force inside the running base plate 2d to assist the patient's knee joint in rehabilitation training, and the ball 2g set at the bottom of the running base plate 2d assists in sliding at the bottom of the running base plate 2d, thereby improving the smoothness of driving the running base plate 2d to slide on the floor when the patient performs hip joint rehabilitation activities. The patient can rotate the soles of the feet to drive the footrest h15 to rotate while performing knee joint rehabilitation activities. During the rotation of the footrest h15, the center ball x9 is used to rotate inside the center groove x1 on a fixed axis, and the sliding ball x6 cooperates to slide on the inner wall of the guide groove x3 inside the upper end of the chassis x7 to improve the smoothness of the rotation of the rotating disk x4 on the upper end of the chassis x7, so that the footrest h15 on the upper end of the rotating disk x4 can rotate on a fixed axis to assist the patient's ankle joint in rehabilitation activities. Through this joint rehabilitation mobilizer, the patient's ankle, hip and knee joints can be rehabilitated at the same time, thereby improving the effect of comprehensive rehabilitation activities for the leg joints.
