Description

Technical Field

[0001] This invention relates to the field of medical assistive device technology, and in particular to a postoperative rehabilitation device for patients and its usage method. Background Technology

[0002] Pelvic floor muscle dysfunction is a common complication after urological surgery, mainly manifested as urinary incontinence and pelvic organ prolapse, which seriously affects the patient's postoperative quality of life and physical and mental recovery. As a key muscle group in the pelvic cavity, the pelvic floor muscles are like a tough "hammock" that firmly supports pelvic organs such as the bladder, uterus, and rectum. Their function is directly related to many important physiological aspects such as urination and defecation control and reproductive health. Rehabilitation training is a means to promote the recovery of pelvic floor muscle function. The bridge leg abduction and inward clamping exercise is one of the effective training methods for postoperative pelvic floor muscle rehabilitation. This exercise can achieve pelvic floor muscle training by naturally contracting the pelvic floor muscles when the buttocks are raised, combined with the force of abducting and clamping the legs. Currently, patients experiencing pelvic floor muscle rehabilitation training exhibit the following deficiencies: 1. It is difficult to grasp the requirement of "lifting the buttocks (lifting the pelvic floor muscles) before abducting and inwarding the legs". Often, the legs are abducted arbitrarily when the buttocks are not lifted and the pelvic floor muscles are not contracted, resulting in poor training effect and even aggravating pelvic floor muscle injury due to improper force exertion. 2. During training, patients have difficulty controlling the range and force of leg abduction and inward clamping, which reduces the training effect; 3. The height cannot be adjusted according to the patient's lower leg length, which reduces the patient's comfort during training and affects the rehabilitation effect. Summary of the Invention

[0003] In view of the above situation and to overcome the defects of the prior art, the purpose of this invention is to provide a postoperative rehabilitation device for patients and its usage method, which effectively solves the problems that patients cannot perform the movements properly when doing pelvic floor muscle training, thus affecting the training effect and making it difficult to control the training range and intensity.

[0004] The technical solution is as follows: The present invention includes a base plate, a rectangular tube with an upward opening fixed on the left side of the base plate, a column that can move up and down inside the rectangular tube, a support beam in the front-back direction fixed at the upper end of the column, a moving groove in the front-back direction with an opening to the right on the support beam, two inverted triangular annular grooves facing each other in the front and back connected on the left side of the moving groove, the two inverted triangular annular grooves being symmetrical in the front and back, two moving rods facing each other in the front and back slidingly connected inside the moving groove, a moving block that can move up and down on the left side of the moving rod, a guide post that can move back and forth on the moving block, the guide post being able to be inserted into the corresponding inverted triangular annular groove, the two moving rods moving in the order of first moving simultaneously in opposite directions - then moving relative to each other - finally moving in opposite directions, an inverted L-shaped moving plate fixed on the lower side of the two moving rods respectively, and a constraint strap for restraining the lower leg on the opposite side of the two moving plates respectively; The support beam has an inverted L-shaped support rod fixed at the middle of the right end. The support rod is fixed with a support shaft in the front and rear axial direction. A mountain-shaped swing plate is rotatably connected to the support shaft. A coil spring is fitted on the support shaft. One end of the coil spring is fixed to the support shaft and the other end is fixedly connected to the swing plate. Arc-shaped grooves coaxial with the support shaft are opened on the two movable plates respectively. Two arc-shaped rods are fixed on the left side of the swing plate. The arc-shaped rods can be inserted into the corresponding arc-shaped grooves. The support beam has a U-shaped groove with an opening facing right on the left side. The right side of the U-shaped groove is connected to the moving groove. A U-shaped rod that can move left and right is provided in the U-shaped groove. Friction blocks are fixed at the upper and lower ends of the right side of the U-shaped rod, and the friction blocks can contact the left end face of the moving rod.

[0005] Compared with the prior art, the present invention has the following advantages: This invention is novel in concept and ingenious in structure. It is designed with a swing plate, an arc-shaped rod and an arc-shaped groove. The locking of the moving rod can only be released when the patient’s buttocks are raised to form a straight line with the thighs and upper body (i.e. the pelvic floor muscles are fully contracted), allowing the legs to perform abduction and inward clamping movements. This ensures that the training movements are standardized and improves the effect of pelvic floor muscle training. The system is equipped with an inverted triangular annular groove, a first limiting groove, and a second limiting groove to limit the range of abduction and inclination of the legs, preventing the range from being too large or too small. Furthermore, by rotating the handwheel to adjust the resistance of the friction block to the moving rod, the force exerted by the legs can be adjusted. This allows for flexible adjustment of the training intensity based on the patient's postoperative recovery, enabling personalized rehabilitation training.

[0006] The rectangular tube, column, and limiting holes allow for flexible adjustment of the support beam height according to the patient's lower leg length, ensuring a proper fit between the patient's knee and the pad. The pad and restraint straps, secured with Velcro, provide convenient fixation and a close fit to the lower leg, reducing patient discomfort during training, enhancing the rehabilitation experience, and facilitating efficient recovery of pelvic floor muscle function. It also trains abdominal and inner thigh muscles, making it highly practical. Attached Figure Description

The right side of the U-shaped groove 17 is connected to the movable groove 5. The U-shaped groove 17 is equipped with a U-shaped rod 18 that can move left and right. Friction blocks 19 are fixed at the upper and lower ends of the right side of the U-shaped rod 18, and the friction blocks 19 can contact the left end face of the movable rod 7.

[0019] In order to enable the column 3 to move up and down within the rectangular tube 2 and to limit the height of the column 3, the column 3 is slidably connected to the rectangular tube 2. The column 3 has multiple limiting holes 20 distributed in the vertical direction and facing forward. A T-shaped column 21 is slidably connected to the front side of the rectangular tube 2. The rear end of the T-shaped column 21 can be inserted into the corresponding limiting hole 20. A tension spring 22 is fitted on the T-shaped column 21. One end of the tension spring 22 is fixed to the rectangular tube 2 and the other end is fixedly connected to the stepped surface of the T-shaped column 21.

[0020] To enable the movable block 8 to move up and down on the movable rod 7, and the guide post 9 to move back and forth on the movable block 8, two vertical T-slots 23 are provided on the left side of the movable rod 7. The movable block 8 is slidably connected to the T-slots 23. A spring 24 is fixed at the lower end of the movable block 8, and the other end of the spring 24 is fixedly connected to the bottom of the T-slots 23. A sliding hole with an opening facing left is provided on the movable block 8. The guide post 9 is slidably connected to the sliding hole. A compression spring 25 is fixed at the right end of the guide post 9, and the right end of the compression spring 25 is fixedly connected to the bottom of the sliding hole.

[0021] To enable the two moving rods 7 to move in the order of first moving simultaneously in opposite directions, then moving relative to each other, and finally moving in opposite directions, the left sides of the opposite sides of the two inverted triangular annular grooves 6 are respectively connected to the first limiting grooves 26. The opposite sides of the two first limiting grooves 26 are respectively connected to the corners of the lower sides of the corresponding inverted triangular grooves. The opposite sides of the two first limiting grooves 26 are inclined surfaces. The left sides of the upper sides of the two inverted triangular annular grooves are respectively connected to the second limiting grooves 27. The opposite ends of the two second limiting grooves 27 are respectively connected to the outer corners of the corresponding inverted triangular grooves. The opposite sides of the two second limiting grooves 27 are inclined surfaces.

[0022] In order to restrain the patient's lower leg on the movable plate 10 and increase the patient's comfort, the opposite sides of the two movable plates 10 are respectively fixed with soft pads 28 of the same shape, and the right ends of the two movable plates 10 are respectively fixed with U-shaped cloth strips 29. The restraint strap 11 is fixedly connected to the left end of the movable plate 10, and the free end of the restraint strap 11 passes through the U-shaped cloth strip 29 and is then glued to itself by the Velcro assembly.

[0023] To facilitate the operation of the swing plate 13, a first fixing ring seat 30 is fixed to the rear side of the base plate 1. Multiple second fixing ring seats 31 are fixed on the base, distributed in the left and right direction and located to the right of the first fixing ring seat 30. The rear side of the second fixing ring seat 31 has a notch 32 with the opening facing downward. A pull rope 33 is fixed to the left side of the swing plate 13. The free end of the pull rope 33 passes through the lower side of the rectangular tube 2 and through the first fixing ring seat 30 before being fixed with a ball stop 34.

[0024] In order to enable the U-shaped rod 18 to move left and right, the left side of the support beam 4 is threaded with a screw 35, the right end of the screw 35 extends into the U-shaped groove 17 and is rotatably connected to the U-shaped rod 18, and the left end of the screw 35 extends out of the support beam 4 and is fixed with a handwheel.

[0025] To achieve better performance, clearance grooves 36 are provided on the opposite sides of the two movable rods 7 and the opposite sides of the two soft pads 28.

[0026] A postoperative rehabilitation device for patients and its method of use, the method of use including the following steps: Step 1: The patient restrains both lower legs on the corresponding movable plates 10 respectively, and the patient lies flat on his / her upper body. The patient inhales and lifts his / her buttocks upward. At the same time, the swing plate 13 swings upward under the action of the coil spring 14. When the patient's thighs, buttocks and upper body are in a straight line, the pelvic floor muscles naturally lift and contract, and the arc rod 16 completely disengages from the arc groove 15, releasing the lock on the movable rod 7. Step Two: The patient's legs simultaneously abduct the moving plate 10, causing the two moving rods 7 to move in opposite directions. When the guide post 9 moves to the outer corner of the inverted triangular annular groove 6, it inserts into the second limiting groove 27 under the action of the compression spring 25. At this time, the legs can only perform an inward clamping motion, and the legs cause the two moving plates 10 to move relative to each other. When the patient's knees move inward to their limit, the guide post 9 moves to the inner corner of the inverted triangular annular groove 6. As the patient's legs abduct, the guide post 9 inserts into the first limiting groove 26 under the action of the compression spring 25, and the two moving rods 7 move back to their initial state, completing a complete sequence of "abduction-clamping-slight abduction to the initial state". The patient can maintain the posture of raising the hips and the upper body in a straight line, and repeat the above movements 3-5 times. Each movement is coordinated with the breathing rhythm to train the pelvic floor muscles, abdominal muscles, and inner thigh muscles. Step 3: After the training, the patient keeps both legs in the initial position, then slowly lowers the buttocks and presses down on the swing plate 13. The pelvic floor muscles relax, the swing plate 13 swings downward and compresses the coil spring 14, the arc plate is inserted into the arc groove 15, and the moving plate 10 is locked, restricting the patient's thighs from moving freely and preventing the patient from performing the abduction and inward clamping of both legs, thus completing one training cycle.

[0027] When the present invention is in use, the column 3 is set to the lowest position, the angle between the swing plate 13 and the column 3 is the smallest, the ball stop 34 is located to the right of the second fixed ring seat 31 on the far right, the compression spring 25 is compressed, the guide column 9 is set in the first limiting groove 26, the moving block 8 is located at the lowest side, the friction block 19 is not in contact with the left end face of the moving rod 7, the arc rod 16 is inserted into the arc groove 15, and the two moving rods 7 are locked in the initial state. When a patient needs to perform pelvic floor muscle training, the patient first stands on the base plate 1, with the inner side of the left knee joint in contact with the front soft pad 28. Observe the height of the knee joint and the soft pad 28. If the height of the upright 3 needs to be adjusted, move the pull rope 33 out from the notch 32 of the multiple second fixed ring seats 31. The swing plate 13 will swing upward under the action of the coil spring 14, but not to the point that the arc rod 16 moves out of the arc groove 15. Then pull the T-shaped rod outward, the tension spring 22 is stretched, and after the inner end of the T-shaped rod disengages from the limiting hole 20, maintain the current state and move upward. The moving column 3 and support beam 4, the moving rod 7, the moving plate 10 and the swing plate 13 move upwards. When the highest position of the patient's knee is level with the upper end of the soft pad 28, the support beam 4 stops moving, the T-shaped rod is released, and the inner end of the T-shaped rod is inserted into the corresponding limiting hole 20 under the action of the tension spring 22. The height of the support beam 4 is limited. The blocking ball 34 is pulled, the pull rope 33 is tensioned, and the swing plate 13 swings downward to the initial angle. Then, the free end of the pull rope 33 is embedded in the notch 32, and the retaining ring is blocked at the right end of the corresponding second fixed ring seat 31. The patient sits on the base plate 1 with knees bent. The restraint strap 11 is wrapped around the lower legs and then passed through the U-shaped cloth strip 29 and glued to itself via the Velcro assembly. The two lower legs are restrained to the corresponding moving plates 10 respectively. The patient's upper body is lying flat. At this time, the patient's buttocks are in contact with the swing plate 13. The pull rope 33 is moved out of the notch 32. The blocking ball 34 is no longer blocked by the second fixed ring seat 31. The patient inhales and lifts his buttocks upward. At the same time, the swing plate 13 swings upward gradually under the action of the coil spring 14. When the patient's thighs, buttocks and upper body are in a straight line, the pelvic floor muscles naturally lift and contract. The arc rod 16 is completely disengaged from the arc groove 15, releasing the lock on the moving rod 7. The patient maintains a raised buttocks and contracted pelvic floor muscles, with both legs simultaneously abducting the movable plate 10. This causes the two movable rods 7 to move in opposite directions. The guide post 9 gradually slides from the first limiting groove 26 into the inverted triangular annular groove 6, compressing the compression spring 25. This causes the two movable blocks 8 to move in opposite directions and upwards, stretching the spring 24. When the guide post 9 moves to the outer corner of the inverted triangular annular groove 6, it inserts into the second limiting groove 27 under the action of the compression spring 25. At this point, the patient's legs are abducted to their maximum angle. Under the action of the second limiting groove 27, the legs can only be clamped inwards. The legs cause the two movable plates 10 to move relative to each other. The guide post 9 moves from the second limiting groove 27 to the upper side of the inverted triangular annular groove 6, compressing the compression spring 25. When the patient's knees move inwards to their limit, the support rod 12 and the movable rod 7... Within the clearance groove 36, the guide post 9 moves to the corner of the inner side of the inverted triangular annular groove 6, allowing the patient's legs to only abduct. As the patient's knees move outward, the moving block 8 moves downward under the action of the spring 24, causing the moving block 8 to slide the guide post 9 into the inner side of the inverted triangular annular groove 6. As the patient's legs abduct, the guide post 9 gradually moves to the corner of the lower side of the inverted triangular annular groove 6, corresponding to the first restriction groove 26. Under the action of the compression spring 25, the guide post 9 inserts into the first restriction groove 26, and the two moving rods 7 move to the initial state, completing a complete sequence of "abduction-inclination-slight abduction to the initial state". The patient can maintain the posture of raising the hips and the upper body in a straight line, repeating the above movements 3-5 times. Each movement is coordinated with the breathing rhythm to train the pelvic floor muscles, abdominal muscles, and inner thigh muscles. After the training, the patient keeps both legs in the initial position, then slowly lowers the buttocks and presses down on the swing plate 13. The pelvic floor muscles relax, the swing plate 13 swings downward and compresses the coil spring 14, the arc plate is inserted into the arc groove 15, and the moving plate 10 is locked, restricting the patient's thigh movement and making it impossible to perform the abduction and inward clamping of both legs, thus completing one training cycle.

[0028] It is noteworthy that during the process of the patient's buttocks and upper body being in a straight line and maintaining this posture, the legs drive the moving plate 10 to move. If the buttocks are lowered during the process of the legs being abducted and clenched, the arc-shaped plate may not be inserted into the arc-shaped groove 15, but the arc-shaped plate will be located in front of or behind the moving plate 10. Combined with the limiting effect of the first limiting groove 26 or the second limiting groove 27 on the guide post 9, the movement of the moving plate 10 will be restricted, thereby restricting the free movement of the patient's legs. Therefore, the patient can only perform the abduction and clenching of the legs when the buttocks and upper body are in a straight line. Thus, the pelvic floor muscles are exercised by the natural contraction of the pelvic floor muscles when the buttocks are raised, combined with the force of the abduction and clenching of the legs, thereby improving the training effect of the pelvic floor muscles.

[0029] If the training intensity needs to be adjusted according to the patient's postoperative physical condition, turn the handwheel. The handwheel drives the screw 35 to rotate and move to the right. Since the U-shaped rod 18 is slidably connected to the U-shaped groove 17, the U-shaped rod 18 drives the friction block 19 to move to the right and squeezes the moving rod 7. At the same time, the patient can move the moving rod 7 with both hands and feel the friction (resistance) applied by the friction block 19 to the moving rod 7. If it meets the patient's physical training needs, stop turning the handwheel. Due to the self-locking characteristic of the screw drive, the friction block 19 always remains in the current state. The patient can then lift their hips and perform abduction and adduction exercises with both legs. By adjusting the resistance applied to the moving rod 7, the training effect on the pelvic floor muscles can be enhanced.

[0030] When using this invention, the number of training sessions can be adjusted according to the patient's postoperative recovery and under the guidance of medical staff, so as to achieve personalized and gradual pelvic floor muscle rehabilitation training.

[0031] The invention includes a first fixing ring seat 30 to fix the pull rope 33, prevent the free end of the pull rope 33 from being placed randomly, and facilitate the user to adjust the stop ball 34 and the free end of the pull rope 33.

[0032] The hook and loop fastener assembly in this invention includes hook and loop fastener attachments and hook and loop fastener attachments, which are existing technologies and will not be described in detail here.

[0033] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, which will not be described in detail here.

When the patient's knees move inward to their limit, the guide post (9) moves into the inverted triangular annular groove (6). At the inner corner, as the patient abducts both legs, the guide post (9) is inserted into the first limiting groove (26) under the action of the compression spring (25), and the two moving rods (7) move to the initial state, completing a complete sequence of "abduction-in-slight abduction to the initial state". The patient can maintain the posture of raising the buttocks and the upper body in a line, and repeat the above movements (3)-(5) times. Each movement is coordinated with the breathing rhythm to achieve training of the pelvic floor muscles, abdominal muscles and inner thigh muscles. Step 3: After the training, the patient keeps both legs in the initial position, then slowly lowers the buttocks and presses down the swing board (13), relaxes the pelvic floor muscles, swings the swing board (13) downward and compresses the coil spring (14), inserts the arc plate into the arc groove (15), locks the moving plate (10), restricts the patient's thighs from moving freely, and makes it impossible to perform the abduction and inward clamping of both legs, thus completing one training cycle.
