Description

Technical Field

[0001] This utility model relates to the field of assistive rehabilitation protective gear technology, and in particular to an orthopedic medical clamping and fixation device. Background Technology

[0002] Orthopedics is one of the most common departments in major hospitals. It mainly studies the anatomy, physiology and pathology of the musculoskeletal system and uses drugs, surgery and physical methods to maintain and develop the normal shape and function of this system. In orthopedic medical treatment, it is often necessary to fix and clamp the patient's arm. Therefore, orthopedic clamping and fixation devices are usually used to stabilize and fix fractures, dislocations or other orthopedic surgeries. They play an important role in treating fractures and supporting bone healing, and can greatly improve the patient's recovery.

[0003] Existing orthopedic medical clamping and fixation devices are not easy to adjust the spacing of the clamps in actual use. If the user's arm is too thick or too thin, it can easily lead to unstable clamping and affect bone recovery. Utility Model Content

Straps B are convenient to cooperate with straps A for fixation.

[0009] As a further embodiment of this utility model, one side of both the upper arm clamp and the forearm clamp is fixedly connected to a support rod by bolts, wherein one side of each set of support rods is fixedly connected to a fixing plate, and the fixing plate facilitates the support of the adjustment plate.

[0010] As a further embodiment of this utility model, a limit bolt is fixedly connected to the surface of the fixed plate, and a fixing nut is threaded to one end of the limit bolt, which facilitates positioning.

[0011] As a further embodiment of this utility model, the bottom of the other two sets of support rods is fixedly connected to an adjustment plate.

[0014] (III) Beneficial Effects

[0015] This utility model provides an orthopedic medical clamping and fixation device, which has the following beneficial effects:

[0016] 1. This orthopedic medical clamping and fixation device, through the adjustment of component settings, allows the user's arm to be placed on the corresponding clamp during use. Depending on the user's arm thickness, rotating the knob causes the threaded rod to rotate on one side of the positioning plate, while simultaneously rotating on the limiting plate. This, in turn, causes the two sets of upper arm clamps or two sets of forearm clamps to separate to a suitable distance, thus achieving the effect of adjusting the clamp spacing. This prevents the user's arm from being too thick or too thin, which could lead to unstable clamping and affect bone recovery, thereby improving the adjustability and applicability of the orthopedic medical clamping and fixation device.

[0017] 2. This orthopedic medical clamping and fixation device, through the setting of an inflation component and a buffer component, allows the user to clamp and fix the patient's arm while continuously pressing the balloon through the connecting tube. This inflates the balloon, providing support. Because the balloon is relatively soft, it can better conform to the patient's arm. In the event of an external impact, the impact force compresses the protective plate, causing it to compress the positioning telescopic rod and the buffer spring to deform and generate elasticity, thus buffering the impact. Furthermore, the internal inflatable balloon can also effectively cushion the impact, thereby improving the safety of the orthopedic medical clamping and fixation device. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figures 1 to 6This utility model provides a technical solution: an orthopedic medical clamping and fixation device, including two sets of upper arm clamps 1 and two sets of forearm clamps 2. Several sets of adjustment components 3 are fixedly connected to the bottom of the upper arm clamps 1 and one side of the forearm clamps 2. The adjustment components 3 allow for adjustment of the clamp spacing, preventing unstable clamping due to excessively thick or thin arms, which could affect bone recovery. This improves the adjustability and applicability of the orthopedic medical clamping and fixation device. Sub-hook and loop fasteners 4 are fixedly connected to the inner walls of both the upper arm clamps 1 and the forearm clamps 2. A female hook and loop fastener 5 is adhesively connected to the surface of the sub-hook and loop fastener 4. An inflation component 6 is fixedly connected to the top of the female hook and loop fastener 5. The inflation component 6 and the buffer component 7 buffer impacts, improving the safety of the orthopedic medical clamping and fixation device. Several sets of buffer components 7 are fixedly connected to the bottom of the upper arm splint 1 and the outer side of the forearm splint 2. A protective plate 8 is fixedly connected to one end of the buffer component 7. The adjustment component 3 includes a positioning piece 301 fixedly connected to the bottom of the upper arm splint 1. A threaded rod 302 is rotatably connected to one side of the positioning piece 301. A limiting piece 303 is threadedly connected to the surface of the threaded rod 302. The limiting piece 303 is fixedly connected to the bottom of one set of upper arm splint 1. The inflation component 6 includes an inflatable airbag 601 fixedly connected to the top of the female Velcro 5. A connecting tube 602 is connected to one side of the inflatable airbag 601. A balloon 603 is connected to one end of the connecting tube 602. The buffer component 7 includes a positioning telescopic rod 701 fixedly connected to the outer side of the forearm splint 2. A buffer spring 702 is sleeved on the surface of the positioning telescopic rod 701.

[0027] Two sets of straps A9 are fixedly connected to one side of the upper arm splint 1 and the forearm splint 2, and two sets of straps B10 are fixedly connected to one side of the other upper arm splint 1 and the forearm splint 2. The straps B10 are used to cooperate with the straps A9 for fixation.

[0028] One side of both the upper arm clamp 1 and the forearm clamp 2 is fixedly connected to a support rod 11 by bolts. One side of each of the two sets of support rods 11 is fixedly connected to a fixing plate 12. The fixing plate 12 serves to support the adjusting plate 15.

[0029] A limit bolt 13 is fixedly connected to the surface of the fixed plate 12. One end of the limit bolt 13 is threadedly connected to a fixing nut 14, which serves as a positioning device.

[0030] The bottom of the other two sets of support rods 11 are fixedly connected to adjustment plates 15. The surface of the adjustment plates 15 is provided with a sliding groove. The fixed plate 12 is rotatably connected to one side of the adjustment plate 15. The adjustment plate 15 facilitates the adjustment of the support angle.

[0031] The bottom surface of one end of the strap A9 is provided with a hook surface, and the surface of the strap B10 is provided with a rough surface. The rough surface serves to connect and fix the strap A9 to the hook surface.

[0032] The surface of the limiting piece 303 is provided with a threaded hole that matches the threaded rod 302. One end of the threaded rod 302 is fixedly connected to a knob 16. The knob 16 facilitates the rotation of the threaded rod 302.

[0033] In this invention, the working steps of the device are as follows:

[0034] First step: When using, place the person's arm on the corresponding clamp plate, and turn the knob 16 according to the different arm thicknesses of the person, so that the threaded rod 302 rotates on the side of the positioning plate 301, and at the same time the threaded rod 302 rotates on the limiting plate 303, thereby driving the two sets of upper arm clamp plates 1 or the two sets of forearm clamp plates 2 to separate to a suitable distance.

[0035] The second step: When in use, while the person clamps and fixes the arm with the corresponding clamp, they continuously press the balloon 603 to add air to the inside of the inflatable balloon 601 through the connecting tube 602, so that the inflatable balloon 601 inflates to support the patient's arm. Because the inflatable balloon 601 is relatively soft, it can better fit the patient's arm.

[0036] Third step: When subjected to external impact, the impact force squeezes the protective plate 8, causing the protective plate 8 to compress the positioning telescopic rod 701 and the buffer spring 702 to deform under force and generate elastic force to buffer the impact. In turn, the internal inflatable airbag 601 can also effectively buffer the impact.
