Background

In medical work, bone surgery is common, where use of a contoured bone extension pin splint is used. The prior art special-shaped bone lengthening needle splints are generally square, and the needle tracks therein are all parallel, such as straight needle tracks. Because the needle tracks are parallel to each other, the special-shaped bone extension needle cannot bear transverse shearing force, and the bone healing of a patient can be adversely affected. Some clamping blocks can achieve the effect of dispersing stress by changing the direction of the needle track, but the clamping blocks are square, so that uneven stress is also possible during use.

Therefore, there is a need to design a device that better relieves stress and improves the healing efficiency of human bone.
