[0022] Referring to the accompanying drawings, a chuck-type external fixing clamp includes a clamping plate 10 and a coiling member 20 located at both ends of the clamping plate 10. The coiling member 20 is movable along the length direction of the clamping plate 10. The clamping plate 10 includes a first clamping plate 11 and a second clamping plate 12. A rotating disk 30 is disposed between the first clamping plate 11 and the second clamping plate 12. A rotation limiting mechanism is disposed on the rotating disk 30. The coiling member 20 includes a first chuck 21 and a second chuck 22.

[0023] Figure 1 The bottommost strap mounting opening is shown as a comparative example, without the strap installed. The rear view and front view of this utility model are symmetrical. And for ease of illustration, Figure 4-6 The return spring is omitted.

[0024] Reference Figure 1 , Figure 1 The leg is fitted with a chuck-type external fixation splint, with the upper splint being the first splint 11 and the lower splint being the second splint 12.

[0025] The movable coiling component 20 along the length of the clamping plate 10 includes three options: only the first chuck 21 is movable along the length of the first clamping plate 11; only the second chuck 22 is movable along the length of the second clamping plate 12; and both the first chuck 21 and the second chuck 22 are movable along the length of the first clamping plate 11 and the second chuck 22 are movable along the length of the second clamping plate 12. Preferably, the first chuck 21 is movable along the length of the first clamping plate 11, so that the translation of the upper section can accommodate different leg lengths. The first chuck 21 and the second chuck 22 are respectively coiled around the thigh and calf.

[0026] The splint 10 is used for external fixation of fractures or soft tissue injuries. Compared with existing one-piece bindings, the disc binding 20 of this invention is lighter in weight, and the gaps between the disc bindings 20 provide good air permeability. Furthermore, the tightness can be adjusted at any time by attaching straps to the disc binding 20, and the joint angle can be adjusted by rotating the disc 30, making it flexible and convenient.

[0027] Furthermore, the rotating disk 30 includes a limiting disk 31 fixedly connected to the first clamping plate 11 and a gear disk 32 fixedly connected to the second clamping plate 12. A hinge shaft 33 is provided at the center of the limiting disk 31 and the gear disk 32. A rotary switch 40 is rotatably hinged to the hinge shaft 33. The rotary switch 40 restricts the rotation of the limiting disk 31 relative to the gear disk 32.

[0028] Furthermore, two sets of limiting discs 31 and two sets of toothed discs 32 are arranged in parallel. The limiting discs 31 are located inside the two sets of toothed discs 32. The rotary switch 40 is located between the two sets of limiting discs 31. The rotary switch 40 includes a rotary pressure rod 41. A rotary groove 42 is provided at the front end of the rotary pressure rod 41. The front end of the rotary groove 42 is sleeved on the hinge shaft 33. A return spring 43 is provided between the rear inner wall of the rotary groove 42 and the hinge shaft 33. A limiting rod 44 is provided on the rotary pressure rod 41 at the tooth opening of the toothed disc 32. When the return spring 43 is in its natural state, the limiting rod 44 is located in the tooth groove 321 of the toothed disc 32.

[0029] Furthermore, the limiting disk 31 and the toothed disk 32 are concentric, the limiting disk 31 is provided with a limiting claw 311, the tooth groove 321 of the toothed disk 32 is located on the outside of the limiting disk 31, and the limiting rod 44 is provided between the limiting disk 31 and the tooth groove 321.

[0030] Furthermore, a pair of toothed grooves 321 are symmetrically arranged on both sides of the clamping plate 10, and the limiting rods 44 are respectively located in the toothed grooves 321 on their respective sides.

[0031] Thus, when the angle needs to be adjusted, press the rotary switch 40, rotate the pressure rod 41 to drive the limit rod 44 to disengage from the tooth groove 321 of the toothed disc 32, rotate the first clamping plate 11 and / or the second clamping plate 12 along the limit disc 31 to the required angle, release the rotary switch 40, and the return spring 43 causes the rotating pressure rod 41 to drive the limit rod 44 back into the tooth groove 321, and lock the clamping plate 10.

[0032] Referring to the accompanying drawings, the adjustment range of the rotating disc of this utility model is at least -10° to 120°. Preferably, the length of the tooth groove 321 of the toothed disc 32 can be set longer as needed, so that the adjustment angle can be larger to accommodate different angles of knee flexion and flexion, making rehabilitation more convenient.

[0033] Furthermore, the inner wall of the coiled component 20 is provided with a mounting limiting groove 23 along the arrangement direction of the clamping plate component 10, and the first clamping plate 11 and the second clamping plate 12 are fixed in the mounting limiting groove 23 with screws.

[0034] This makes it convenient for the tray bundle 20 to be moved and installed along the arrangement direction of the clamping plate 10.

[0035] Furthermore, the first chuck 21 is movable along the arrangement direction of the first clamping plate 11, and the first clamping plate 11 is provided with a plurality of adjustment holes 111 in sequence along its length direction, and a locking screw is provided between the adjustment hole 111 and the first clamping plate 11.

[0036] This makes it easy to adjust the height of the first chuck 21 to accommodate different leg lengths.

[0037] Furthermore, the said coiled bundle 20 is provided with strap mounting openings 24 on both sides, and straps are provided on the strap mounting openings 24, with Velcro straps on the straps.

[0038] The product's tray strap 20 is designed in groups and separates, and uses Velcro closures for easy observation of wounds or surgical incisions, facilitating dressing changes and treatment. This Velcro closure design also allows for adjustment for individuals with different leg sizes, making it more comfortable to wear. Furthermore, the straps in this product are perforated, providing good breathability.

[0039] Furthermore, the first chuck 21 is provided in two sets along the length of the first clamping plate 11; the second chuck 22 is provided in two sets along the length of the second clamping plate 12.

[0040] Referring to the attached drawings, this utility model is a chuck-type external fixation splint. Alternatively, the chuck-type binding component 20 can be controlled by a zipper for opening, closing, and tightening; that is, a zipper is installed on the straps of the binding component 20. This utility model uses a grouped, separate binding component 20, making it more suitable for emergency medical situations, but also suitable for general cases. For individuals with broken skin, dressings need to be changed 3 to 7 days after splint fixation, eliminating the need for removal of traditional fixation splints. Furthermore, compared to integrated Velcro or integrated zipper-type splints, it eliminates the need for additional straps and is lighter in weight.

[0041] In summary, this utility model is lightweight, breathable, and allows for easy adjustment of tightness and joint angle, making it flexible and convenient.

[0042] This invention can be used not only for leg fractures, but also for the fixation of fractures in other limbs and the trunk. It can also be used for external fixation of muscle, ligament, and soft tissue injuries.
