Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a multi-morphological adjustable ankle joint adapter. Background Technology

[0002] The ankle, located at the junction of the lower leg and foot, consists of seven tarsal bones, the metatarsals of the foot, and the bones of the lower leg. It is crucial for normal lower limb movement. The ankle is an extremely complex joint structure, and coupled with the weight it bears throughout the body in daily life, these factors make it more prone to problems.

[0003] Ankle sprains are the most common sports injury, accounting for approximately 40% of all sports injuries. The ankle joint is formed by the distal ends of the tibia and fibula and the talus. Its anatomical and physiological characteristics make it relatively prone to inversion and eversion sprains during plantar flexion. If ankle injuries are not treated and rehabilitated promptly and correctly, the strength of the ankle ligaments will decrease, leading to reduced ankle stability and decreased proprioception. This instability makes the ankle joint more susceptible to re-injury, or causes chronic injury symptoms such as pain and swelling during movement. It can also lead to postural imbalances and chronic injuries to other joints, resulting in a chain reaction of injuries.

[0004] Ankle rehabilitation training is particularly important, and scientific and accurate rehabilitation training has a positive impact on prognosis. Current ankle rehabilitation training equipment only provides exercise training for one dimension of the ankle joint and cannot meet the multi-dimensional training needs of the ankle.

One end of the connecting component is rotatably connected to the rotational power component, and the other end is detachably and fixedly connected to the flipping component. The foot fitting component is fixedly mounted on the flipping component. The flipping component includes a displacement seat and an adjustment rod. The foot fitting component includes a foot pedal, which is fixed to the displacement seat. One end of the adjustment rod is rotatably connected to the displacement seat, and the rotation angle is adjustable. The other end can be connected to the connecting component. Flexing rods are horizontally arranged on both sides of the displacement seat, and the end of the flexing rod facing away from the displacement seat can be connected to the connecting component.

[0008] Optionally, the displacement seat consists of a fixed plate and side plates disposed on both sides of the fixed plate.

[0024] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0025] This application discloses a multi-form adjustable ankle joint adapter. (Refer to...) Figure 1 The ankle adapter includes a foot fitting component 1, a flip component 2, an adapter component 3, and a rotational power component 4. The adapter component 3 connects the flip component 2 and the rotational power component 4 and is fixed to the rotational power component 4. The flip component 2 and the adapter component 3 are detachably connected. The foot fitting component 1 is fixed to the flip component 2. The patient can place their foot on the foot fitting component 1. The flip component 2 can be used to adjust the relative position of the patient's foot and the rotational power component 4, thereby enabling multi-dimensional training adjustments for the user's ankle abduction / adduction, inversion / eversion, and toe flexion / dorsiflexion.

[0026] Reference Figure 2 , Figure 3The foot adapter component 1 includes a foot pedal 11 and a foot length adjustment block 12. The foot pedal 11 is horizontally fixed on the flip component 2, and the foot length adjustment block 12 is movably disposed at one end of the top of the foot pedal 11. The foot length adjustment block 12 has two positioning grooves 124, which are parallel and spaced apart. The opening direction of the positioning grooves 124 is consistent with the length extension direction of the foot pedal 11. The foot pedal 11 has a fixing hole, and locking screws 121 for fixing the positions of the foot pedal 11 and the foot length adjustment block 12 are inserted into the positioning grooves 124 and the fixing hole. A positioning hole is formed between the two positioning grooves 124. The foot pedal 11 has a strip groove 111, which is parallel to the two positioning grooves 124. A sliding screw 123 is inserted into the strip groove 111 and the positioning hole, and the foot pedal 11 is fixed by a sliding nut 122. The foot length adjustment block 12 can be adjusted within the limitation of the strip groove 111, so that the foot length adjustment block 12 can be adjusted and fixed according to the foot length of different users.

[0027] Furthermore, a foot strap 13 is provided at the end of the foot pedal 11 away from the foot length adjustment block 12, and an ankle strap 14 is provided between the foot strap 13 and the foot length adjustment block 12, which, together with the foot length adjustment block 12, increases the stability of the patient's foot fixation.

[0028] refer to Figure 4 The flipping assembly 2 includes a positioner 21, which consists of a fixed plate 211 and side plates 212 vertically fixed to both sides of the fixed plate 211. The bottom wall of the foot pedal 11 is horizontally fixed to the top wall of the fixed plate 211. An adjustment rod 22 is rotatably mounted between the two side plates 212 via a pivot. A gasket is installed between the side wall of the adjustment rod 22 and the inner side wall of the side plate 212. Multiple pin holes 213 are provided on both side walls, and the pin holes 213 are evenly spaced in a semi-circle with one end of the pivot as the center. A through hole is provided on the side wall of the adjustment rod 22 opposite to the pin hole 213. An adjustment pin 214 for fixing the angle of the adjustment rod passes through the pin hole 213 and the through hole, so that the angle of the adjustment rod 22 relative to the foot pedal 11 can be rotated according to training needs. When ankle inversion / eversion and adduction / abduction training is required, the end of the adjustment rod 22 away from the side plate 212 is inserted and fixed to the rotating assembly.

[0029] The adapter assembly 3 includes an adapter rod 31, a connecting tube 32, and a clamping handle 33.

[0030] Reference Figure 5Flexing rods 23 are horizontally welded to the outer walls of both side plates 212. When the ankle needs to perform toe flexion / dorsiflexion training, the end of the flexing rod 23 away from the side plate 212 can be inserted and fixed in the connecting tube 32. The flexing rod 23 is set perpendicular to the rotation power assembly 4. The foot pedal 11 is parallel to the ground. The patient places his foot on the foot pedal 11 to achieve toe flexion / dorsiflexion training of the ankle.

[0031] Reference Figure 6 When the ankle needs inversion / outversion training, the free end of the adjustment rod 22 can be inserted into the connecting tube 32 for fixation. The adjustment rod 22 is set parallel to the foot pedal 11 and perpendicular to the rotation power component 4, so that the patient sits on the chair with his legs straight and his feet fixed on the foot pedal 11, thereby realizing the inversion / outversion training of the ankle.

[0032] Reference Figure 7 When the ankle needs adduction / abduction training, the free end of the adjusting rod 22 can be inserted into the connecting tube 32 for fixation. The adjusting rod 22 is set perpendicular to the foot pedal 11, and the foot pedal 11 is set parallel to the rotary power assembly 4. The patient sits on a chair with his legs straight and his feet fixed on the foot pedal 11, thereby achieving ankle adduction / abduction training.

[0033] See again Figure 1 Insert the free end of the adjusting rod 22 into the connecting tube 32 and fix it with the adjusting pin 214. At this time, the adjusting rod 22 and the foot pedal 11 are set at a certain angle. The foot pedal 11 is located above the rotary power assembly 4. The patient sits on the chair with his feet extended downwards and diagonally forward, and his feet are fixed on the foot pedal 11, thereby realizing the training of ankle inversion / eversion combined adduction / abduction.

[0034] The implementation principle of the multi-morphological adjustable ankle adapter in this application is as follows: by mimicking the three-dimensional rotational axis of the ankle joint, precise settings for the three training dimensions of the ankle joint can be achieved. Through the combination and adjustment of structures, it adapts to the rehabilitation training of different users' ankle joints for dorsiflexion / plantarflexion, inversion / eversion, and adduction / abduction.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
