Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a joint recovery training device after orthopedic surgery. Background Technology
[0002] After surgery for a joint injury, patients typically rest in bed. However, prolonged bed rest is detrimental to recovery. To prevent joint contractures or stiffness caused by fibrous adhesions during bed rest, it is necessary to move the joints to promote blood flow. Patients need to undergo rehabilitation training. In addition, rehabilitation training is of great therapeutic value for patients with hemiplegia, muscle disorders, neurological diseases, and cerebrovascular diseases. It can significantly reduce pain and accelerate the recovery of joint function.
[0003] Currently, existing joint rehabilitation training devices are mostly divided into two types: upper limb elbow joint training and lower limb knee joint training. Each is used for different joint rehabilitation training. However, there is no joint rehabilitation training device on the market that can be used for both upper limb and lower limb joint training, resulting in poor compatibility and certain shortcomings. Therefore, we propose a joint rehabilitation training device for postoperative orthopedic surgery. Utility Model Content

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Please see Figures 1 to 5 This utility model provides a technical solution: a joint recovery training device after orthopedic surgery, including a seat 1 and two training rods 2. A backrest 3 is fixedly installed on one side of the seat 1, and two lower mounting plates 4 are fixedly installed on the bottom of the seat 1. Side mounting plates 5 are fixedly installed on both sides of the backrest 3. The lower mounting plates 4 and the side mounting plates 5 are provided with mounting grooves 6. The training rods 2 cooperate with the mounting grooves 6. Several insertion holes 7 are provided inside the bottom of the training rods 2. Pull grooves 8 are provided inside the lower mounting plates 4 and the side mounting plates 5 and below the mounting grooves 6. A sliding rod 9 is slidably installed inside the pull groove 8. A sliding plate 10 is fixedly installed at one end of the sliding rod 9. Two insertion rods 11 are fixedly installed on the top of the sliding plate 10. The insertion rods 11 cooperate with the insertion holes 7. A first spring 12 is installed on the outside of the sliding rod 9. The sliding plate 10 cooperates with the first spring 12. The sliding plate 10 is slidably connected to the inner wall of the pull groove 8. A pull plate 13 is fixedly installed at the other end of the sliding rod 9.
[0022] The training rod 2 has a groove 14 inside its top. A lead screw 15 is rotatably mounted inside the groove 14. A sleeve block 16 is threaded onto the outside of the lead screw 15. A limit ring is fixedly mounted in the middle of the lead screw 15, and the limit ring mates with the sleeve block 16. Two guide rods 17 are fixedly mounted inside the groove 14 and above the lead screw 15. The sleeve block 16 is slidably connected to the guide rods 17. The sleeve block 16 has holes inside that mate with the lead screw 15 and the guide rods 17. The sleeve block 16 is slidably connected to the inner wall of the groove 14. A second spring 18 is mounted on the outside of the guide rod 17. One end of the second spring 18 is fixedly connected to one side of the sleeve block 16. A slider 19 is mounted on the side. The other end of the second spring 18 is fixedly connected to one side of the slider 19. The slider 19 has a hole inside that mates with the guide rod 17. The slider 19 mates with the second spring 18. An L-shaped push plate 20 is fixedly mounted on the top of the slider 19. The other end of the lead screw 15 extends to the outside of the training rod 2 and a turntable 21 is fixedly mounted thereon. A pin is inserted inside the turntable 21. Several pin holes are opened inside one side of the training rod 2. The pin and pin holes are used to fix and limit the turntable 21, so as to prevent the lead screw 15 from rotating during training, which would cause the sleeve 16 to shift and affect the training intensity.
[0023] In summary, when using this orthopedic postoperative joint recovery training device, the training rod 2 is installed according to whether the patient's training needs are for the upper or lower limb. For the lower limb, the pull plate 13 at the bottom of the mounting plate 4 is pulled down, which in turn pulls the sliding rod 9 and the sliding plate 10 downwards, causing the insertion rod 11 to move into the pull groove 8. Then, the training rod 2 is inserted into the mounting groove 6. The installation position of the training rod 2 is adjusted according to the length of the patient's lower limb. After adjusting to the appropriate length, the pull plate 13 is released, and the first spring 12 will rebound and push the sliding plate 10 back to its original position. Then, the insertion rod 11 can be inserted into the insertion hole 7 to install and fix the training rod 2. Then, according to the patient's training intensity requirements, the position of the sleeve block 16 can be adjusted. When adjusting, first pull out the pin inside the turntable 21, then rotate the turntable 21 to drive the lead screw 15 to rotate, thereby driving the sleeve block 16 to move through the thread. After the adjustment is completed, insert the pin into the turntable 21 and then insert it into the pin hole on one side of the training rod 2. Finally, training can be carried out. During training, the patient sits on the seat 1 and then puts his feet on the L-shaped push plate 20 and extends them forward to carry out training.
[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
