Description

Technical Field

[0001] This utility model relates to the field of medical finger bone fixation technology, specifically to an adjustable medical finger bone external fixation splint. Background Technology

[0002] Finger fractures are common bone injuries of the hand, also known as bamboo fractures. They are usually caused by direct external force on the finger, and can be transverse, oblique, spiral, comminuted, or involve the articular surface. After a fracture, local pain and swelling occur, and finger flexion and extension are limited. When there is significant displacement, angular deformities may occur in the proximal and middle phalanges, preventing the finger from actively straightening. After treatment, finger fractures require external fixation. Splints made of wood, bamboo, cardboard, or plastic are fixed to the reduced limb using bandages or ligatures to facilitate healing of the fracture ends under relatively static conditions. This is combined with gradual functional exercises to promote fracture healing and restore limb function; this treatment method is also known as splinting therapy.

[0003] Small splint fixation is a commonly used method for phalangeal fractures, suitable for transverse fractures and mild oblique fractures. By using small splints and bandages, the fracture site is fixed in the appropriate position to promote fracture healing. Small splint fixation is widely used in clinical practice due to its ease of operation and low cost. Existing medical external fixation splints for phalanges mostly use fixed-length splints. However, since the length of each person's finger is different, mismatches in length can easily occur during use, leading to unsatisfactory fixation results and affecting the recovery outcome. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable medical finger bone external fixation splint to improve the problem of mismatched lengths during the use of fixation splints.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An adjustable medical finger bone external fixation splint includes two splints, an elastic element connecting the two splints, and a fixing element. The splints are available in various lengths and have a first extension plate at one end. The elastic element has second extension plates at both ends. The first extension plate has a first threaded hole through it, and the second extension plate has a connecting through hole. A bolt that is threadedly connected to the first threaded hole is inserted into the connecting through hole.

[0007] By adopting the above technical solution, when the length of the splint needs to be adjusted, the bolt is turned to unscrew it from the first threaded hole, thus disassembling the splint. A splint of suitable length is then replaced and secured with bolts, allowing for splint length adjustment to meet the needs of different splint lengths during finger bone fixation. Furthermore, the elastic components can be reused for targeted splint replacement, further conserving resources.

[0008] Optionally, the bolt has a rotating handle at one end of its nut, the rotating handle being made of an elastic plastic material, and the end wall of the rotating handle having a mounting groove for the bolt nut to be inserted.

[0009] By adopting the above technical solution, rotating the handle increases the friction during bolt tightening, achieving a labor-saving effect. This ensures convenience and comfort when connecting the clamping plate and elastic element using the bolt through the first and second extension plates. No additional wrench or screwdriver is needed, making it convenient for operators.

[0010] Optionally, the rotary handle is embedded with a magnetic element that attracts the bolt.

[0011] By adopting the above technical solution, after the bolt nut is embedded in the mounting groove, the fixing force between the bolt and the rotating handle can be increased, and the bolt will not easily fall off when the outer plastic material of the rotating handle wears.

[0012] Optionally, the outer wall of the rotating handle is provided with anti-slip texture.

[0013] By adopting the above technical solution, a labor-saving effect can be achieved when tightening bolts using a rotary handle.

[0014] Optionally, the outer wall of the rotary handle is provided with a force-applying groove.

[0015] By adopting the above technical solution, the use of the rotary handle to tighten bolts can achieve the effects of saving effort and preventing slippage, thereby increasing the comfort of the user experience.

[0016] Optionally, the first extension plate is provided with an extension tube that is threadedly connected to a bolt on the side away from the second extension plate, and the inner wall of the extension tube is embedded with an anti-slip rubber ring.

[0017] By adopting the above technical solution, the length of the thread engagement between the bolt and the first extension plate can be increased, the fixing force of the bolt screwing into the first extension plate and the second extension plate can be increased, and the bolt can be prevented from loosening.

[0018] Optionally, a protective cover is fitted onto the outer wall of the extension tube.

[0019] By adopting the above technical solution, the extension tube is fitted inside the protective cover to prevent the protruding parts of the bolts or extension tube from abrading the skin, thus ensuring comfort during use.

[0020] In summary, this utility model has at least one of the following beneficial technical effects:

[0021] 1. This utility model divides the splint into three parts: two symmetrical splints and an elastic element. The splints and the elastic element are connected by an extension plate and bolts. By adjusting the length of the splints, the problem of poor recovery effect caused by the mismatch between the finger length and the splint length is solved.

[0022] 2. This utility model has a rotating handle at one end of the bolt located at its nut, which facilitates the rotation of the bolt. In addition, an extension tube that engages with the bolt is provided on the side of the first extension plate away from the second extension plate, which makes it less prone to loosening and ensures its convenience and stability during use.
