Description

Technical Field

[0001] This utility model belongs to the field of medical devices, and more specifically, it relates to a foot fixation device. Background Technology

[0002] Foot immobilizers are commonly used devices for the treatment and rehabilitation of sports injuries. Their function is to provide support and fixation for the foot, protecting the injured joint during postoperative healing, reducing pain, and shortening recovery time. Currently, traditional foot immobilizers mostly use an L-shaped fixation frame structure with elastic bandages to support and fix the joint between the leg and foot. However, in actual treatment, depending on the severity of the joint injury, different support and bending angles are required between the leg and foot. Therefore, the fixed structure of traditional foot immobilizers prevents adjustment of the support angle between the leg and foot. Furthermore, the installation position of the traditional elastic bandages within the L-shaped fixation frame cannot be changed. Since human feet vary in size, traditional foot immobilizers are not effectively suitable for patients with different foot sizes, resulting in poor flexibility in wearing them. Utility Model Content

Threaded rod 13, leg strap 18, foot strap 22, and foot strap 23; one end of the leg strap 18 is installed on the left side of the left side plate 1, and the other end of the leg strap 18 is hinged with a buckle 5; one end of the leg strap 3 is installed on the right side of the right side plate 1, and Velcro 4 is sewn onto the leg strap 3; one end of the foot strap 22 is installed on the upper side of the clip 9, and Velcro 4 is sewn onto the foot strap 22; the clip 9 has a through hole running through both sides. Structure: One end of the foot strap 23 is installed on the upper side of the clamping plate 9, and the other end of the foot strap 23 is hinged to a buckle 5; a clamping nut 11 is screwed onto the outer side of the clamping bolt 10; a knob 8 is installed at the front end of the threaded rod 13, and a sliding block 24 is engaged with the outer side of the threaded rod 13. A pull rod 17 is hinged to the left and right sides of the sliding block 24. The rear end of the pull rod 17 is hinged to the non-center position of the turntable 16. The turntable 16 is welded to the end of the protruding post of the fixed plate 20; there are two sets of turntables 16, which are symmetrically distributed on the left and right sides. The left side of the right turntable 16 has a protruding post, and the outer side of the left turntable 16 is printed with markings; there are two sets of brackets 21, which are symmetrically distributed on the left and right sides. A scale 15 is welded to the rear end of the left bracket 21, and a limit plate 14 is welded to the rear end of the right bracket 21. A guide rod 12 is welded to the front end of the bracket 21, and a base frame 7 is welded to the front end of the guide rod 12.

[0025] When wearing the foot fixation device, the knob 8 is first manually turned. The knob 8 rotates the threaded rod 13. Since the outer thread of the threaded rod 13 is threadedly engaged with the threaded through-hole of the sliding block 24, and the guide rod 12 is inserted into the through-hole of the sliding block 24, the threaded rod 13 can drive the sliding block 24 to slide back and forth along the guide rod 12. The sliding block 24 drives the pull rod 17, which is hinged to the left and right sides, to move back and forth synchronously. The pull rod 17 then pushes and pulls the turntable 16, which is hinged to the rear end, to rotate. 6 drives the welded fixing plate 20 to rotate, which in turn drives the leg pad 2 to flip forward or backward. At this time, according to the 0-90 degree scale marking on the dial 15 aligned with the outer side marking of the left turntable 16, a suitable rotation angle is selected to complete the positioning and adjustment of the folding angle between the leg pad 2 and the foot plate 6. Then, the through hole of the clamping piece 9 is aligned with the long through groove of the base frame 7 and a suitable position is selected. Then, the clamping bolts 10 are inserted into the through hole of the clamping piece 9 and the long through groove of the base frame 7 in sequence. Tighten the clamping nut 11 onto the threaded part of the clamping bolt 10. The clamping nut 11, together with the clamping bolt 10, secures the foot strap 22 and foot pull strap 23 to the appropriate position on the base frame 7 to fit the length of the patient's foot. Then, place the patient's foot on the upper side of the footplate 6, and place the patient's leg inside the concave arc-shaped structure of the leg pad 2. Then, slip the leg pull strap 18 and leg strap 3 onto the outside of the patient's leg. The leg strap 3 is inserted into the buckle 5 and then folded over to extend. At this point, adjust the leg strap according to the size of the patient's leg. Tighten the leg strap 3, then attach the two sets of Velcro 4 of the leg strap 3 together to fix the leg strap 3 and the leg strap 18 to the patient's leg. Put the foot strap 22 and the foot strap 23 on the outside of the human foot. Insert the foot strap 22 into the buckle 5 and then fold it over and extend it. At this time, tighten the foot strap 22 according to the size of the human foot, and then attach the two sets of Velcro 4 of the foot strap 22 together to fix the foot strap 22 and the foot strap 23 to the patient's foot, thus completing the wearing of the foot fixation device.

[0026] In this embodiment, a threaded through hole is provided at the center of the front side of the sliding block 24. The threaded rod 13 is engaged with the threaded through hole of the sliding block 24. The left and right sides of the threaded through hole of the sliding block 24 are symmetrically provided with through holes. The guide rod 12 is inserted into the through hole of the sliding block 24, so that the threaded rod 13 drives the sliding block 24 to move back and forth stably along the guide rod 12, so that the sliding block 24 pulls the pull rod 17 to make the turntable 16 rotate, thus completing the flip adjustment of the leg pad 2.

[0027] In this embodiment, the upper side of the foot plate 6 is provided with a large number of ventilation holes, which not only facilitates the ventilation of the foot skin, but also facilitates the operation of the heat lamp.

[0028] In this embodiment, the limiting plate 14 is provided with a 90-degree arc-shaped through groove that runs from left to right. The protrusion of the right turntable 16 is inserted into the arc-shaped through groove of the limiting plate 14. The protrusion of the right turntable 16 slides along the arc-shaped through groove of the limiting plate 14 and is limited from 0 to 90 degrees to prevent the hinge structure between the leg pad 2 and the foot plate 6 from over-rotating and exceeding the limit range of foot joint movement.

[0029] In this embodiment, the left side of the dial 15 is provided with angle markings from 0 to 90 degrees, and the outer side markings of the left turntable 16 are opposite to the angle markings of the dial 15, making it easier for users to accurately observe the flip angle of the leg pad 2 and the footboard 6, and making the adjustment more intuitive.

[0030] In this embodiment, the leg pad 2 has a concave arc-shaped structure, which makes the human leg fit the leg pad 2 more closely. The outer surface of the concave arc-shaped structure of the leg pad 2 is densely covered with a large number of breathable holes, which not only facilitates the skin of the leg to breathe, but also facilitates the operation of the heat lamp.

[0031] In this embodiment, a through hole is provided at the center of the front side of the base frame 7. The unthreaded end of the outer side of the threaded rod 13 is rotatably connected to the through hole of the base frame 7. Both the left and right sides of the base frame 7 are provided with elongated through grooves.
