What's more serious is that in the process of recovering the injured part, the traditional stent is formed at one time, thick and the internal conditions cannot be observed, so the cast cannot fit the injured part of the patient well, and sometimes the stent compresses tissue, resulting in poor blood circulation, and severe cases can even lead to tissue necrosis

Embodiment
[0050] In this embodiment, the 3D printing method is used to produce the bone scaffold. The use of 3D scanning and additive manufacturing methods can meet this requirement for a patient-tailored fracture support bracket that meets the doctor's requirements. Selecting the appropriate material for 3D printing of the mold can achieve the requirements of lightness, water resistance and ventilation. In terms of appearance, different colors can also be selected according to the requirements of patients.

Abstract
The invention relates to a support and a preparation method, belongs to the field of medical apparatus and instruments, and particularly relates to a skeleton auxiliary support and a preparation method thereof. By means of a three-dimensional scanning technology, three-dimensional model establishing is carried out on the damaged parts of a patient, and the support is generated through the three-dimensional printing technology. Triangular and/or hexagonal hollowed holes are formed in a shell of the support. The skeleton support prepared through the method is good in breathability, small in size, low in weight and sufficient in supporting force, the requirements for small weight, convenience, water preventing and ventilation can be met, and using is more comfortable.
Description
technical field [0001] The invention relates to a bracket and a preparation method, belonging to the field of medical devices, in particular to a bone auxiliary bracket and a preparation method. Background technique [0002] Fractures are a common trauma symptom. Most fractures are repositioned in their original location and immobilized with a cast after emergency treatment and reduction by a physician. These molds can be gypsum, fiberglass, or other synthetic materials. Most of these techniques and materials have been used today without significant improvement since the 19th century. Although these casts can meet the basic requirements clinically, there are some disadvantages of such casts in rehabilitation and orthopaedics. [0003] Typically, a typical patient with a fractured hand and forearm will be placed in the emergency room with a cast or fiberglass cast bracket that weighs about 3-4 pounds. These gypsum or fiberglass cast stents are highly water-repellent, whic...
