Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a post-operative recovery training auxiliary device for joint surgery. Background Art

[0002] Joints refer to the places where bones are connected. According to different connection relationships, they can be mainly divided into movable joints and immovable joints. The elbows, wrists, knees, ankles and other parts of the limbs are all movable joints, and the knee joints are particularly important to the human body. The knee joint is the joint connecting the thigh bone and the calf bone. The knee joint can flex and extend, enabling the human body to perform normal walking, running, jumping and other activities. The cartilage and synovial fluid in the knee joint can cushion the impact of the body during exercise and reduce damage to the body.

[0003] Most of the existing auxiliary devices for post-operative recovery training of the knee joint control the lifting and lowering of the knee to perform rehabilitation training on the knee joint, but cannot perform simultaneous massage on the calf. Massaging the calf can promote local blood circulation, prevent muscle atrophy, promote movement of the lower limb muscles and help restore lower limb motor function. The existing devices do not have an automatic adjustment function. Since the leg lengths of patients are different, the device needs to be manually adjusted when performing recovery training on different patients. After debugging is completed, the patient's leg needs to be manually fixed with a strap.

[0020] refer to Figures 1-8, the shown device is an auxiliary device for postoperative recovery training of joint surgery, comprising a base plate 1 and an air cylinder 11, an adjusting component, comprising two vertical plates 2 symmetrically mounted on the upper surface of the base plate 1, the vertical plate 2 is slidably mounted with a sliding plate 4 at one end away from the air cylinder 11, and a spline shaft 7 is rotatably connected between the two sliding plates 4 at one end away from the air cylinder 11, the outer wall of the spline shaft 7 is symmetrically slidably connected to two support rods 3, the outer wall of the support rod 3 is slidably mounted with a sleeve rod 9, the sleeve rod 9 is fixedly connected to one end away from the support rod 3 with a connecting seat 10, an adjusting rod 12 is rotatably connected in the connecting seat 10, a connecting column 39 is slidably connected in the adjusting rod 12, and two springs 40 are symmetrically mounted on one end of the support rod 3 close to the sleeve rod 9, a snap-fitting hole 42 is provided on the sleeve rod 9, and the spring 40 is adapted to the snap-fitting hole 42; the end of the connecting block 23 away from the base plate 1 is fixedly connected with a universal seat 24, and the universal seat 24 is rotatably connected to the support seat 25, The connecting plate 18 is provided with a slide groove 26, which is slidably connected to the slide seat 28. The end of the slide seat 28 near the connecting block 23 is fixedly connected to the arc clamping plate 29. The end of the connecting block 23 near the slide seat 28 is fixedly connected to the connecting rod 31, and the connecting rod 31 is adapted to the slide seat 28. The connecting plate 18 near the connecting block 23 is fixedly connected to the toothed plate 27. The connecting plate 18 is provided with a connecting hole 17, and the connecting hole 17 is fixedly connected to the clamping block 16, and the clamping block 16 is adapted to the toothed plate 27. The end of the vertical plate 2 near the sliding plate 4 is fixedly connected to the positioning plate 5. A plurality of positioning holes 33 are evenly provided on the positioning plate 5. The sliding plate 4 is slidably connected to the end of the positioning plate 5 by a positioning pin 34, and the positioning pin 34 is adapted to the positioning hole 33. The support rod 3 and the connecting column 39 are both provided with a mounting groove 32, and the mounting groove 32 is fixedly connected to the electric push rod 41, and the output end of the electric push rod 41 is fixedly connected to the arc block.

[0021] In order to improve the convenience of the device, the present invention is provided with an adjustment component, which automatically adjusts the length of the thigh by moving the sliding plate 4 and the sleeve rod 9 in the adjustment component, and automatically adjusts the length of the patient's calf by contracting the adjustment rod 12. As the patient's legs move to the support seat 25, the patient's legs are automatically clamped, and the legs are fixed by the engagement of the tooth plate 27 and the clamping block 16 to avoid accidental injury caused by leg movement during recovery training.

[0022] Specifically, first, place the patient's legs on the support seat 25, slowly push the support plate 14 to move it along the guide seat 13 to perform recovery training on the patient, the patient's thigh squeezes the support rod 3 along the inner wall of the sleeve rod 9, and squeezes the spring in the sleeve rod 9 during the movement, the sliding plate 4 moves along the vertical plate 2, and the positioning pin 34 moves along the positioning plate 5. When the sliding plate 4 and the support rod 3 automatically move to a position suitable for the legs and stop moving, the arc block is squeezed by controlling the electric push rod 41 to move and the spring 40 is squeezed. , so that the protrusion on the spring 40 is engaged with the engaging hole 42 opened on the sleeve rod 9, and the positioning pin 34 is engaged with the positioning hole 33 on the positioning plate 5 under the pressure of the spring, completing the automatic adjustment of the thigh length of the device. It is worth noting that the positioning pin 34 is designed with a bevel and is adapted to the protrusion in the positioning hole 33. When the thrust is too large, the positioning pin 34 will automatically slide out of the positioning hole 33, but when pulled in the opposite direction, the positioning pin 34 is engaged with the positioning hole 33 and cannot slide out, and the spring in the sleeve rod 9 buffers and shocks the leg length adjustment process.

[0023] Secondly, as the support plate 14 slowly moves, the arc plate installed on the shaft between the two connecting seats 10 supports the patient's knees, and the height of the arc plate should be higher than the height of the connecting seat 10 to avoid affecting the movement of the connecting seat 10. The device adjusts the rod 12 along the connecting column 39 under the weight of the patient's calf. When the patient's foot falls into the carrier box 15, the electric push rod 41 is controlled to make the arc block squeeze the spring 40 so that the protrusion on the spring 40 is engaged with the engaging hole 42 on the adjusting rod 12, completing the automatic adjustment of the length of the calf by the device. At the same time, as the patient's leg presses the support seat 25 downward, the connecting block 23 moves downward and pulls the connecting plates 18 closer to each other. Since the slide 28 moves synchronously with the connecting rod 31, when the connecting block 23 moves downward, the slide 28 moves downward synchronously, and the connecting rod 31 gradually extends out along the groove opened on the connecting plate 18. As the connecting plate 18 moves, the support rod 3 gradually approaches along the spline shaft 27, and the connecting column 39 The support base 25 is supported by the support rail 28 and the support rail 29 is supported by the support rail 28. The support rail 25 is supported by the support rail 28 and the support rail 25 is supported by the support rail 28. The support rail 25 is supported by the support rail 28 and the support rail 25 is supported by the support rail 28. The support rail 25 is supported by the support rail 28 and the support rail 25 is supported by the support rail 28. The support rail 25 is supported by the support rail 28 and the support rail 25 is supported by the support rail 28. The support rail 25 is supported by the support rail 28 and the support rail 25 is supported by the support rail 28. The support rail 25 can be rotated at multiple angles to facilitate recovery training. When the leg is automatically clamped, the teeth of the tooth plate 27 are engaged with the block 16 in the connecting hole 17 to prevent the arc plate 29 from loosening during rehabilitation training. It is worth noting that the tooth plate 27 is made of elastic material and will bend and deform when it is engaged with the block 16. It will automatically return to its original shape when the engagement is completed. The above-mentioned clamping and fixing structure and principle for the thigh and calf are the same and will not be repeated here. Moreover, the automatic adjustment of the length of the calf and thigh and the automatic clamping of the leg are performed synchronously by the above device.

[0024] refer to Figures 1-8, an auxiliary component includes a connecting plate 18 fixedly connected to the adjusting rod 12, and the connecting plate 18 is rotatably connected to the support plate 30 at one end close to the air cylinder 11. The two support plates 30 are rotatably connected to the connecting block 23 at one end away from the connecting plate 18. Two mounting plates 35 are fixedly connected at both ends of the connecting block 23. Two pulleys 38 are symmetrically mounted on the mounting plate 35, and the pulleys 38 are rotatably connected to the mounting plate 35. The outer walls of each two pulleys 38 are rotatably connected to a slot belt 36, and a plurality of rollers 37 are evenly mounted in the slot belt 36, and the rollers 37 are rotatably connected to the slot belt 36. Two guide seats 13 are symmetrically mounted on the upper surface of the base plate 1, and a support plate 14 is slidably connected in the guide seat 13. A spline shaft 6 is rotatably connected between the two support plates 14, and a connecting column 39 is connected to the The support plate 14 is rotatably connected, the outer wall of the spline shaft 6 is fixedly connected to the carrier box 15, the outer wall of the carrier box 15 is fixedly connected to the medicine storage box 20, and a plurality of nozzles are evenly installed in the carrier box 15. The upper surface of the bottom plate 1 is slidably connected to the guide rod 19, and the end of the guide rod 19 close to the air cylinder 11 is fixedly connected to the tensioning wheel 45, and the piston plate 8 is slidably connected in the air cylinder 11. The end of the piston plate 8 close to the tensioning wheel 45 is rotatably connected to the hinged plate 43, and the end of the hinged plate 43 away from the piston plate 8 is rotatably connected to the rotating plate 44. An air inlet is provided at the end of the air cylinder 11 away from the tensioning wheel 45, and the end of the air cylinder 11 away from the tensioning wheel 45 is fixedly connected to the mounting bracket 21, and a slide rod 22 is slidably connected to the mounting bracket 21, and a block is fixedly connected to the end of the slide rod 22 away from the piston plate 8.

[0025] In order to improve the patient's recovery speed, the present invention is provided with an auxiliary component. The pulley 38 in the auxiliary component rotates and drives the roller 37 in the slot belt 36 to fit the patient's calf for rolling massage to accelerate blood circulation and promote the recovery of lower limb muscles. The patient's feet are automatically cleaned and dried during the massage process to avoid the inconvenience of cleaning the feet and the breeding of bacteria to infect the wound, which can improve the recovery speed of the patient's wound.

[0026] Specifically, first, after the above-mentioned recovery training device automatically adjusts the leg length and clamps the leg, the motor rotates to drive the belt strip to rotate, and the belt strip rotates to drive the pulley 38, and the rotation of the pulley 38 drives the rotation of the slot belt 36. Since the slot belt 36 is installed on both sides of the connecting block 23 and is arranged parallel to the adjusting rod 12, the slot belt 36 will move synchronously with the movement of the connecting block 23. The rotation of the slot belt 36 drives the roller 37 to rotate close to the patient's calf for massage. As the adjusting rod 12 moves, the tightness of the belt strip changes. The tensioning wheel 45 installed on the guide rod 19 automatically adjusts the tightness of the belt strip to avoid the situation where the belt strip is too loose and cannot drive the slot belt 36 to rotate during the movement of the adjusting rod 12. The rotation of the slot belt 36 does not affect the clamping and fixation of the leg by the arc-shaped clamping plate 29. As the support plate 14 pushes the connecting column 39 gradually rotates, driving the carrier box 15 on the spline shaft 6 to move synchronously.

[0027] Secondly, since the rotating plate 44 is fixedly connected to the output end of the motor, the motor drives the rotating plate 44 to rotate, and the rotating plate 44 pulls the hinged plate 43 and the piston plate 8 to move synchronously. When the piston plate 8 moves along the air cylinder 11 toward the mounting bracket 21, the air cylinder 11 is in the exhaust state. It is worth noting that the piston plate 8 does not contact the mounting bracket 21 during the movement. At this time, the air inlet hole on the air cylinder 11 is pushed by the slide bar 22 to seal the air inlet hole. The air guide tube inputs the gas generated in the air cylinder 11 into the medicine storage box 20. The medicine storage box 20 evenly sprays the cleaning agent inside it onto the patient's feet through the nozzle on the carrier box 15 for disinfection and cleaning. It is worth noting that the medicine storage box 20 is in a sealed state during the operation of the device, and the solubility of air and cleaning agent is very low. When When the piston plate 8 is away from the mounting bracket 21, the air cylinder 11 is in an intake state, and gas enters the air cylinder 11 through the air inlet hole. It is worth noting that when the air cylinder 11 is intaken, the one-way valve in the air guide tube is in an open state to prevent the cleaning agent in the medicine box 20 from flowing back into the air cylinder 11. The air cylinder 11 moves intermittently to spray all the medicines in the medicine box 20 onto the patient's feet. The cleaned medicines are discharged and collected in time along the groove opened at the bottom of the carrier box 15. As the cleaning agent in the medicine box 20 is sprayed and emptied, the gas discharged from the air cylinder 11 automatically dries the patient's feet through the nozzle. It is worth noting that the above-mentioned calf massage and foot cleaning are carried out simultaneously, and the speed of foot cleaning and calf massage is faster than the leg recovery training speed.

[0028] The working principle of the present invention is as follows: the patient's legs are placed on the support seat 25, and the support plate 14 is slowly pushed to move it along the guide seat 13 to perform recovery training on the patient. The patient's thighs are squeezed to move the support rod 3 along the inner wall of the sleeve rod 9, and the sliding plate 4 moves along the vertical plate 2. At the same time, the positioning pin 34 moves along the positioning plate 5. When the sliding plate 4 and the support rod 3 automatically move to a position suitable for the legs and stop moving, the electric push rod 41 is controlled to move to squeeze the arc block to squeeze the spring 40, so that the protrusion on the spring 40 is engaged with the engaging hole 42 opened on the sleeve rod 9. The positioning pin 34 is engaged with the positioning hole 33 on the positioning plate 5 under the pressure of the spring, completing the automatic adjustment of the length of the thigh by the device. As the support plate 14 slowly moves, the space between the two connecting seats 10 is The arc plate installed on the shaft supports the patient's knee. The device adjusts the rod 12 along the connecting column 39 under the weight of the patient's calf. When the patient's foot falls into the carrier box 15, the arc block is squeezed by the electric push rod 41 to make the protrusion on the spring 40 engage with the engaging hole 42 on the adjusting rod 12, thereby completing the device's automatic adjustment of the calf length. At the same time, as the patient's leg presses the support seat 25, the connecting block 23 moves downward to pull the connecting plates 18 closer to each other. Since the slide 28 moves synchronously with the connecting rod 31, when the connecting block 23 moves downward, the slide 28 moves downward synchronously, and the connecting rod 31 gradually extends out along the groove opened on the connecting plate 18. As the connecting plate 18 moves, the support rod 3 gradually approaches along the spline shaft 27, and the connecting plate 18 is connected. The connecting column 39 gradually approaches along the spline shaft 6. When the arc-shaped clamping plate 29 clamps the patient's leg, the support seat 25 stops moving down. When the leg is automatically clamped, the teeth of the toothed plate 27 engage with the clamping block 16 in the connecting hole 17 to prevent the arc-shaped clamping plate 29 from loosening during rehabilitation training. After the above-mentioned recovery training device automatically adjusts the leg length and clamps the leg, the motor rotates to drive the belt strip to rotate, and the belt strip rotates to drive the pulley 38. The rotation of the pulley 38 drives the rotation of the slot belt 36. Since the slot belt 36 is installed on both sides of the connecting block 23 and is arranged parallel to the adjusting rod 12, the slot belt 36 will move synchronously with the movement of the connecting block 23. The rotation of the slot belt 36 drives the roller 37 to rotate close to the patient's calf. During massage, the motor drives the rotating plate 44 to rotate, and the rotating plate 44 pulls the hinged plate 43 and the piston plate 8 to move synchronously. When the piston plate 8 moves along the air cylinder 11 toward the mounting frame 21, the air cylinder 11 is in the gas outlet state. The air guide tube inputs the gas generated in the air cylinder 11 into the medicine storage box 20, and the medicine storage box 20 evenly sprays the cleaning agent inside the medicine storage box 20 onto the patient's feet through the nozzle on the carrier box 15 for disinfection and cleaning. The intermittent movement of the air cylinder 11 sprays all the medicine in the medicine storage box 20 onto the patient's feet. The cleaned medicine is discharged and collected in time along the groove opened at the bottom of the carrier box 15. As the cleaning agent in the medicine storage box 20 is sprayed and emptied, the gas discharged from the air cylinder 11 automatically dries the patient's feet through the nozzle.
