Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a leg length adjustment mechanism for a hemiplegic exoskeleton. Background Technology

[0002] Hemiplegia, a common sequela of neurological diseases, causes motor dysfunction in one side of the body, severely impacting patients' mobility and quality of life. Exoskeletons play a crucial role in the rehabilitation and assisted walking processes of hemiplegic patients, providing essential support and assistance to help them regain the ability to walk and promote the recovery of limb function.

[0003] Existing hemiplegic exoskeleton leg length adjustment devices typically use screws or other fixing devices to adjust the extension and retraction of the leg support before use. However, current devices require repeated tightening and loosening of screws for disassembly and tightening, making the adjustment process cumbersome and difficult to lock and unlock quickly. This increases the difficulty and time cost of operation, resulting in low efficiency. Furthermore, the adjustment accuracy is limited, and it is easy to over-adjust or under-adjust, increasing the patient's discomfort when walking.

[0004] Therefore, it is necessary to design a leg length adjustment mechanism for hemiplegic exoskeleton that can quickly lock and unlock the position of the internal connecting tube to achieve leg length adjustment, is easy to operate, can be adapted to different patients with different leg lengths, improves the accuracy and efficiency of adjustment, and is flexible and convenient to use. Utility Model Content

[0005] To overcome the shortcomings of current equipment, which requires repeated tightening and loosening of screws for disassembly and tightening, resulting in a cumbersome adjustment process, difficulty in quickly locking and unlocking, increased operational difficulty and time costs, low efficiency, and limited adjustment accuracy, which easily leads to over- or under-adjustment and increases patient discomfort while walking, this utility model provides a leg length adjustment mechanism for hemiplegic exoskeleton that can quickly lock and unlock the position of the internal connecting tube for leg length adjustment. It is simple to operate, easy to adapt to different patients with different leg lengths, improves adjustment accuracy and efficiency, and is flexible and convenient to use.

[0006] The technical solution is as follows: A leg length adjustment mechanism for a hemiplegic exoskeleton includes a pretensioning strip, an elastic groove, an elastic plate, a locking head, an outer connecting tube, a guide sleeve, and an inner connecting tube. The inner connecting tube is slidably locked inside the outer connecting tube. An elastic groove is locked on the left side of the inner connecting tube. Multiple pretensioning strips are connected to the outer side of the right side of the elastic groove. All pretensioning strips are in contact with the inner connecting tube. Two locking heads are slidably locked on the inner connecting tube. An elastic plate is connected between the locking heads and is in contact with the inner connecting tube. A guide sleeve is locked on the right side of the outer connecting tube and is in contact with the inner connecting tube.

[0007] Preferably, the pretensioning strips are all made of rubber.

[0008] Preferably, the elastic sheet is V-shaped.

[0009] Preferably, the diameter of the outer connecting pipe is larger than the diameter of the inner connecting pipe.

[0010] As a preferred option, multiple external tube holes are opened on both the front and rear sides of the external connecting tube.

[0011] As a preferred option, the inner connecting tube has two inner tube holes on both the left and right sides for easy adjustment.

[0012] Beneficial effects: 1. This utility model allows the clamp head to be pressed and moved away from the outer tube hole and into the inner tube hole. Then, the outer connecting tube is fixed by hand, and the inner connecting tube is pulled to move and adjust, so that the clamp head can be locked with any outer tube hole. This allows for quick locking and unlocking of the inner connecting tube position adjustment to achieve leg length adjustment. The operation is simple and easy to adapt to different patients with different leg lengths, improving the accuracy and efficiency of adjustment, and making it flexible and convenient to use.

[0013] 2. During the adjustment process, the elastic groove tension ensures that the upper ends of the outer connecting pipe and the inner connecting pipe are always in a pre-tightened state. The pre-tightening strip prevents the elastic groove from slipping, and the guide sleeve guides the device to prevent shaking. This ensures that the device does not shake when locked, reduces the risk of falling, makes it sturdy and reliable, and improves the stability of use. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0020] A leg length adjustment mechanism for a hemiplegic exoskeleton, such as Figures 1-4 As shown, the device includes a pretensioning strip 1, an elastic groove 11, an elastic sheet 2, a clamping head 21, an outer connecting tube 3, a guide sleeve 4, and an inner connecting tube 5. The inner connecting tube 5 is slidably clamped to the inner side of the outer connecting tube 3. The diameter of the outer connecting tube 3 is larger than that of the inner connecting tube 5. The elastic groove 11 is clamped to the left side of the inner connecting tube 5. Three pretensioning strips 1 are connected to the outer right side of the elastic groove 11. All pretensioning strips 1 are in contact with the inner connecting tube 5. All pretensioning strips 1 are made of rubber and have good elasticity. For improved durability and wear resistance, the inner connecting tube 5 is slidably secured with two front and rear clamping heads 21, with an elastic sheet 2 connected between the clamping heads 21. The elastic sheet 2 is in contact with the inner connecting tube 5 and is V-shaped. The outer connecting tube 3 has seven external tube holes 31 on both its front and rear sides for easy adjustment. The guide sleeve 4 is secured to the right side of the outer connecting tube 3 and contacts and cooperates with the inner connecting tube 5. The inner connecting tube 5 has two front and rear internal tube holes 51 on both its left and right sides for easy adjustment.

[0021] This device can be used when adjusting leg length in hemiplegic exoskeleton patients. The elastic plate 2 contacts the inner connecting tube 5, and the elastic plate 2 is pushed to insert into the inner connecting tube 5, allowing the locking head 21 to pass through the inner tube hole 51. The elastic plate 2 is V-shaped. Next, the elastic groove 11 is engaged with the inner connecting tube 5, allowing the pre-tensioning strip 1 to contact the inner connecting tube 5. The pre-tensioning strip 1 is made of rubber, possessing good elasticity and wear resistance. Then, the inner connecting tube 5 contacts the outer connecting tube 3, and the outer connecting tube 3 is pushed to move, allowing the locking head 21 to pass through any of the outer tube holes 31. Next, the guide sleeve 4 is engaged with the outer connecting tube 3, allowing the guide sleeve 4 to contact the inner connecting tube 5. The device is then assembled. The diameter of the outer connecting tube 3 is larger than the diameter of the inner connecting tube 5. When adjustment is needed, the locking head 21 is pressed to disengage from the outer tube hole 31 and move into the inner connecting tube. Inside the inner tube hole 51, the elastic sheet 2 deforms. Then, the outer connecting tube 3 is fixed by hand, and the inner connecting tube 5 is pulled to move and adjust. After moving to the appropriate position, the clamp 21 is released, and the elastic sheet 2 returns to its original position, so that the clamp 21 engages with any of the outer tube holes 31 for locking. This allows for quick locking and unlocking to adjust the position of the inner connecting tube 5 to achieve leg length adjustment. The operation is simple and easy to adapt to different patients with different leg lengths, improving the accuracy and efficiency of adjustment. It is flexible and convenient to use. During the adjustment process, under the tension of the elastic groove 11, the upper ends of the outer connecting tube 3 and the inner connecting tube 5 are always kept in a pre-tight state. The pre-tightening strip 1 prevents the elastic groove 11 from slipping. The guide sleeve 4 guides and prevents shaking, thus ensuring that the device does not shake when locked, reducing the risk of falls. It is sturdy and reliable, improving the stability of use. Then, the device can be used.
