Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a rehabilitation stretching device for postoperative Achilles tendon shortening and ankle joint stiffness. Background Art

[0002] During clinical rehabilitation treatment, it was found that ankle stiffness and Achilles tendon contracture are caused by various reasons, mainly fractures near the ankle joint, ankle-related ligament surgery, Achilles tendon rupture repair surgery, Achilles tendon shortening caused by neurological diseases, and other functional problems. Due to prolonged immobilization and lack of effective rehabilitation measures, varying degrees of ankle joint dysfunction (such as joint stiffness, muscle atrophy, and limited range of motion) are caused. Due to the anatomy of the ankle joint and Achilles tendon, the functional impairment caused by Achilles tendon contracture is difficult to rehabilitate, and is time-consuming and labor-intensive, bringing great difficulties to patients and therapists. To address this problem, the current rehabilitation method is usually to stretch the Achilles tendon with manual techniques. However, due to the high tension of the Achilles tendon and the poor ductility of the contracted tissue, it is difficult to effectively expand the range of motion of the joint, and it also causes significant strain on the therapist's hands, bringing uncertainty to the patient's later rehabilitation effect.

DETAILED DESCRIPTION

[0017] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following is a brief introduction to the drawings required for use in the embodiments. Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0018] Please see Figures 1 to 3 A rehabilitation stretching device 10 for postoperative Achilles tendon shortening and ankle stiffness includes a traction plate 20, an instep strap 30, an ankle strap 40, an Achilles tendon strap 50, and a strap adjustment mechanism 60. One end of the traction plate 20 is a foot binding part for fixing the foot, and the other end of the traction plate 20 is a traction part for the rehabilitation therapist to traction. The instep strap 30, the ankle strap 40, the Achilles tendon strap 50, and the strap adjustment mechanism 60 are located at the foot binding part. The instep strap 30, the ankle strap 40, the Achilles tendon strap 50 are located at the On the front side of the traction plate 20, the strap adjustment mechanism 60 is located on the back side of the traction plate 20, and the instep strap 30, ankle strap 40, and Achilles tendon strap 50 are respectively fixedly connected to the strap adjustment mechanism 60 to adjust the length of the strap. The instep strap 30 is located at the front end of the foot binding, the ankle strap 40 is located at the rear end of the foot binding, and the Achilles tendon strap 50 is adjacent to the instep strap 30; when the foot is fixed, the ankle strap 40 intersects with the Achilles tendon strap 50, and the ankle is restrained between the ankle strap 40 and the Achilles tendon strap 50.

[0019] The traction plate 20 of the present invention has three functions. The first function is to support the foot. The second function is to fix the foot in conjunction with the strap. The third function is the principle of a force-saving lever, which makes it easier for therapists to perform rehabilitation treatment and for rehabilitation therapists to perform rehabilitation treatment on patients. For example, anyone who has had an Achilles tendon rupture knows that if the foot remains motionless after the Achilles tendon is injured, the muscles and Achilles tendon will atrophy, but the patient will not be able to mobilize the muscle groups for movement. Even if they can move, the movement is not standardized, which will affect recovery. At this time, the rehabilitation therapist must use the traction plate 20 to perform professional and standardized movements on the foot, which will help the foot recover as soon as possible.

[0020] The material of the bandage should be breathable and have poor elasticity, so that the patient cannot easily move his foot out of the bandage and affect recovery.

[0021] In order to allow the sole of the foot to breathe, a plurality of holes may be added to the bottom of the traction plate 20 .

[0022] The strap adjustment mechanism 60 of the present invention is used to adjust the tightness of the strap. Different people have different foot shapes, so different people need different strap lengths.

[0023] In a preferred embodiment, the strap adjustment mechanism 60 includes three strap adjustment components with the same structure and corresponding to the instep strap 30, ankle strap 40, and Achilles tendon strap 50. The strap adjustment component includes two support plates 601, a reel 602, and a knob 603. The support plate 601 is fixedly connected to the back of the traction plate 20. The support plate 601 is provided with a threaded hole. Both ends of the reel 602 pass through the threaded holes and are mounted on the support plate 601. The reel 602 is provided with an external thread for easy rotation. One end of the reel 602 is sleeved and connected to the knob 603 to control the rotation of the reel 602, and the strap is wrapped around the reel 602.

[0024] Under the action of the thread, although the reel 602 will also move along the axial direction during the rotation process, the adjustable length of the strap is generally only 0 to 2 cm, and one turn of the thread can basically meet the required length without increasing the length too much, and the strap will not interfere with the support plate 601.

[0025] Of course, in other preferred embodiments, the reel 602 can also be fixed by means of a ratchet or pawl. The present invention does not recommend the use of motor control because motors are not as reliable as manual control, manual operation is not prone to accidents, and manual operation is also very convenient, so there is no need to increase costs by using motors.

[0026] The width of the strap can be adjusted according to actual conditions, and the principle is that the patient will not feel tightened.

[0027] In a preferred embodiment, the width of the instep strap 30 is 3 to 6 centimeters.

[0028] In a preferred embodiment, the width of the ankle strap 40 is 4 to 6 centimeters.

[0029] In a preferred embodiment, the width of the Achilles tendon strap 50 is 4 to 6 centimeters.

[0030] In a preferred embodiment, the length of the traction plate 20 is 80-100 cm.

[0031] Patients typically lie in bed for treatment, inevitably moving their feet side to side, causing them to pronate or supinate. This is especially true given the curved surface of the heel, which provides poor support stability. Furthermore, due to the steep slope of the heel, the Achilles tendon strap 50 may occasionally slip downward.

[0032] Therefore, in a preferred embodiment, the rehabilitation stretching device 10 for postoperative Achilles tendon shortening and ankle joint stiffness further includes a correction plate 70. The correction plate 70 is perpendicularly and fixedly connected to the end of the binding part of the traction plate 20. A parabolic limiting hole 701 is provided at the connection between the correction plate 70 and the binding part to limit the heel.

[0033] When the patient lies flat on the bed, under the support of the correction plate 70, the foot will not swing left and right. At the same time, with the limiting hole 701 provided on the correction plate 70, the heel is limited in the limiting hole, and the foot will not move relatively to the traction plate 20, which is more conducive to fixation. The Achilles tendon strap 50 will also be limited between the heel and the correction plate 70 and will not slide down.

[0034] Please refer to Figure 4 , in a preferred embodiment, the rehabilitation stretching device 10 for postoperative Achilles tendon shortening and ankle joint stiffness further includes an independent traction mechanism 80 for facilitating the patient's independent operation. The independent traction mechanism 80 includes a traction member 801, a connecting plate 802, a U-shaped support frame 803, a pull rope 804, and a handle 805. One end of the traction member 801 is hinged to the traction plate 20, and the other end of the traction member 801 is fixedly connected to the connecting plate 802. Both ends of the connecting plate 802 are slidably connected to the U-shaped support frame 803. The connecting plate 802 can slide along the traction direction. Both ends of the connecting plate 802 are also connected to one end of the pull rope 804, and the other end of the pull rope 804 is fixedly connected to the handle 805.

[0035] The traction member 801 can be a rope or a rod, and its function is to be able to drive the traction plate 20 to move along the human body direction.

[0036] In the middle and late stages of rehabilitation, when the patient has a relatively good recovery, in addition to the rehabilitation therapist operating the traction plate 20 to conduct rehabilitation training on the patient, the patient himself can also use the independent traction mechanism 80 for rehabilitation treatment, so that the recovery can be faster. Especially when the patient meets the discharge conditions and without the help of a rehabilitation therapist, the patient can also conduct rehabilitation training at home by himself, making the rehabilitation effect better.

[0037] The above-disclosed are only the preferred embodiments of the present invention. Of course, the scope of the rights of the present invention cannot be limited by this. Those of ordinary skill in the art can understand the implementation of all or part of the above processes, and the equivalent changes made according to the claims of the present invention still fall within the scope covered by the invention.
