Description

Technical Field

[0001] This utility model relates to the field of medical rehabilitation equipment technology, specifically a tendon recovery device for rehabilitation medicine. Background Technology

[0002] Rehabilitation medicine is an important branch of clinical medicine, primarily targeting patients with functional impairments caused by diseases, trauma, surgery, or congenital defects. Through comprehensive interventions, it helps them restore or improve physical function, enhance their self-care ability, and improve their quality of life. Tendons, as a type of tough connective tissue in the human body, mainly connect muscles and bones. They are key structures that transmit force and drive joint movement during muscle contraction. Tendons are widely distributed; for example, the flexor and extensor tendons in the hand control the bending and straightening of the fingers, while the Achilles tendon connects the calf muscles to the calcaneus, assisting in actions such as tiptoeing and jumping. After tendon injury, tendon recovery devices become important rehabilitation tools. The core function of these specialized devices is to promote tendon healing, restore tendon elasticity and tension through assisted movement, and prevent complications such as adhesions and muscle atrophy, ultimately helping patients regain normal limb function.

[0003] Chinese Utility Model Patent Publication No. CN212016596U discloses a lower limb exercise device for rehabilitation. The device, as described in the specification, allows the inner cylinder to reciprocate via a drive screw in a double telescopic mechanism when the patient's limbs are weak. This movement of the patient's foot, fixed to the foot pedal structure, assists in training. However, the foot pedal, being a component in direct contact with the patient's foot, is prone to accumulating dirt after prolonged use. The lack of an effective disassembly and assembly structure makes cleaning and maintenance of the foot pedal extremely cumbersome. Furthermore, the absence of an effective hand support structure may affect the patient's balance and safety during training. Summary of the Invention

A limit groove 1407 is opened on the side of the rectangular rod 1401 away from the backrest 2.

[0036] The quick-release assembly 15 includes a crossbar 1501 and a connecting rod 1511. The crossbar 1501 has an insertion hole 1502 on the side near the support beam 7, and a sliding hole 1503 and an arc-shaped hole 1504 on the side away from the backrest 2. The crossbar 1501 has a movable groove 1505 inside, and a spring 1506 is slidably installed on the inner wall of the movable groove 1505. The crossbar 1501 is slidably connected to a pin 1507 through the sliding hole 1503 and the arc-shaped hole 1504. A circular piece 1508 and a circular piece 2 1509 are fixedly installed on the outside of the pin 1507. A protrusion 1510 is fixedly installed on the end of the pin 1507 away from the backrest 2. The connecting rod 1511 has a fixing hole 1512 and an arc-shaped hole 2 1513 on the side near the support beam 7.

[0037] Specifically, a foot pedal 1514 is connected to the end of the connecting rod 1511 away from the crossbar 1501. An elastic bandage 1515 is fixedly installed on the outer side of the connecting rod 1511. A protrusion 1516 is fixedly installed on the outer surface of the foot pedal 1514. Multiple protrusions 1516 of the same size are provided. The advantage is that through the design of the foot pedal 1514 and the protrusions 1516, the foot pedal 1514 fits the arch of the foot better, making it easier for the patient to apply force.

The advantage is that, through the design of the movable groove 1505, the spring 1506 and the disc 1509, when the pin 1507 is pulled, the disc 1509 will continue to slide along the movable groove 1505, compressing the spring 1506 and causing it to contract. After the pin 1507 is released, the spring 1506 loses its restriction and quickly rebounds, which can quickly complete the fixing and unlocking of the connecting rod 1511, making it highly practical.

[0040] Example 2: Figure 2-9 As shown, this is an improvement on the previous embodiment.

[0041] Specifically, the limiting groove 1407 has at least three of the same size. The limiting groove 1407 is adapted to the end of the grip 1406 near the sleeve 1404. The advantage is that, through the design of the sleeve 1404, the limiting groove 1407 and the grip 1406, the height of the grip 1406 can be adjusted by rotating the sleeve 1404 to make the grip 1406 fit into different limiting grooves 1407, thus improving the applicability.

[0042] Specifically, there are two identical adjustment components 14 and quick-release components 15, symmetrically distributed along the central axis of the seat cushion 3. The cross-sections of the rectangular rod 1401 and the crossbar 1501 are arranged in a "T" shape. The advantage is that the vertical connection between the rectangular rod 1401 and the crossbar 1501 provides strong structural stability, and the crossbar 1501 is not prone to bending or breaking even when subjected to a large thrust.

[0043] Specifically, a rectangular rod 10 is fixedly installed at the end of the rotating shaft 9 away from the support beam 7. A connector 11 is fixedly installed on the outside of the rectangular rod 10. A counterweight rod 12 is fixedly installed at the end of the connector 11 away from the sleeve column 8. A counterweight plate 13 is inserted and installed on the outside of the counterweight rod 12. The advantage is that, through the design of the counterweight rod 12 and the counterweight plate 13, patients can adjust the training intensity by adding or removing the counterweight plate 13 with the help of medical staff or family members, which helps to develop a targeted recovery plan.

[0044] Working principle: During use, the patient sits on the seat cushion 3. When tendon recovery training is needed, the patient can adjust the grip 1406 using the adjustment component 14 according to their own situation. First, the height of the grip 1406 is adjusted by sliding the circular sleeve 1404 on the rectangular rod 1401. Rotating the circular sleeve 1404 causes the grip 1406 to be inserted into different limiting grooves 1407, fixing the height of the grip 1406. The grip 1406 assists in lower limb exertion, and then the foot is placed against the foot pedal 1514. At the same time, the elastic bandage 1515 can be used for further fixation. The protrusion 1516 on the outer side of the foot pedal 1514 increases the friction between the sole of the foot and the foot pedal 1514. When the patient applies force to push the foot pedal 1514, it simultaneously drives the crossbar 1501, the second rectangular bar 1401, and the pivot 9 to rotate around the sleeve column 8. At the same time, the first rectangular bar 10, the connector 11, the second counterweight bar 12, and the second counterweight plate 13 on the other side of the pivot 9 will generate resistance to ensure training intensity. After long-term use, when the foot pedal 1514 becomes dirty, it can be disassembled and cleaned using the quick-release assembly 15. First, rotate the pin 1507 to turn the side... Align the protrusion 1510 with the arc-shaped hole 1504, pull the pin 1507 to slide along the sliding hole 1503, and at the same time, the circular piece 1509 on the outside of the pin 1507 presses the spring 1506 along the movable groove 1505. After the pin 1507 leaves the fixed hole 1512 and the arc-shaped hole 1513, the connecting rod 1511 can be separated from the crossbar 1501. After cleaning, pull the pin 1507 again to insert the connecting rod 1511 into the insertion hole 1502. Release the pin 1507 to allow the spring 1506 to lose its restraint and drive the pin 1506. 07. Upon rebound, the pin 1507 and the protrusion 1510 pass through the fixing hole 1512, the sliding hole 1503, the arc-shaped hole one 1504, and the arc-shaped hole two 1513 to fix the connecting rod 1511 and the crossbar 1501. At the same time, after the protrusion 1510 passes through the arc-shaped hole one 1504, the pin 1507 is rotated again, and the protrusion 1510 rotates accordingly, so that the protrusion 1510 and the crossbar 1501 come into contact. With the cooperation of the disc one 1508, the pin 1507 and the crossbar 1501 can be fixed. This completes the use process of a tendon recovery device for rehabilitation.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
