Description

Small splint external fixation device in traditional Chinese medicine

technical field

The invention belongs to the technical field of small splints of traditional Chinese medicine, in particular, the invention relates to an external fixation device of small splints of traditional Chinese medicine.

Background technique

In the existing small splint external fixation device in traditional Chinese medicine, the combination technology of the splint body only considers the adaptability to the human limbs, and does not pay attention to the orthotropic characteristics of the combined splint component and the biomechanics between the splint component and the fixed part of the bone. Compatibility and adaptability have been affected, and the adaptability of the splint stiffness and callus strength and the avoidance of stress shielding are not perfect; the external fixation device of the small splint in traditional Chinese medicine is composed of four splints, and the existing device system cannot solve the four splints. Due to the problems of longitudinal length matching adjustment and lateral shaping adjustment of the splint, the combination of the coupling body and the splint member is suitable for a small range of people; moreover, it is difficult to obtain an accurate tension value through fine-tuning the hair and hook strap binding mode. Ribbon binding is a better choice, but the splint is easy to move, and the end of the ribbon is difficult to handle, especially if a single ribbon is used, it is easy to cause the splint to slide and the external fixation to loosen; the operation of external fixation is not yet highly simple.

Therefore, the modernization of traditional Chinese medicine small splint technology must continue to innovate and further improve.

Preferably, the first end of the lock hook plate 15 is fixedly connected with the rotating plate 12, and the lock hook plate 15 The second end is a hook structure, the first end and the second end of the lock hook plate 15 are opposite ends on the width direction of the lock hook plate 15, and the second end of the lock hook plate 15 is for When the clamping part is in the fastening position, hook the locking support 10, and then keep the clamping part in the fastening position, so that the clamping part and the locking support 10 are kept in the state of clamping the belt, so as to avoid the loosening of the belt , convenient, fast, safe and reliable.

The TCM small splint external fixation device with the above structure has the following advantages:

1. A single strap is used to facilitate the adjustment of the position of the splint and maintain the sensitivity of the binding ring; the locking device is used to limit the loosening of the strap to ensure the reliability of the binding ring of the splint device;

2. The horizontal connection device is to make the overall splint device shape according to the lateral biological shape of the patient's arm before wearing the external fixation, and position the splint according to the position where the splint should be placed. It mainly connects the first, second, and third splint components. After shaping The splint device can be placed on the affected limb from bottom to top to form a painless wearing, and the ring buckle and limiter structure are used to limit the free sliding of the splint;

3. The aluminum alloy track is used to position the splint with lateral shaping, which improves the simplicity of external fixation operation.

The present invention has been exemplarily described above with reference to the accompanying drawings. As long as various insubstantial improvements are made by adopting the method concept and technical solutions of the present invention, they all fall within the protection scope of the present invention.
