Freely detachable personalized neck brace based on 3D printing and preparation method thereof

Abstract

The invention relates to a personalized neck brace that can be removed at will based on 3D printing, including front and rear parts of the neck brace, lightweight through holes, threaded fixing parts of different shapes and sizes, and fixing screws. It adopts personalized customization, is consistent with the natural curve of the patient's neck and shoulders, and fits perfectly, which can effectively solve the patient's discomfort caused by long-term wearing. The development and application of 3D printed screw fasteners makes the cervical collar more precise and easier to disassemble and assemble. Several lightweight through-holes designed based on the injury site and the stress analysis of the cervical collar can make the cervical collar both strong and light, relieving the patient's sense of oppression when wearing the cervical collar.

Description

Technical field [0001] The invention relates to the field of medical devices, and in particular provides a detachable personalized cervical collar based on 3D printing and a preparation method thereof. Background technique [0002] A cervical collar is a neck fixation device. Its purpose is to immobilize the neck and rest the neck muscles. It can limit excessive activities of the neck and reduce the impact of cervical vertebra hyperplasia, bone spurs, herniated discs and other compression objects on nerve roots and sympathetic nerves. , the relative friction between the vertebral artery and the cervical spinal cord, reducing the traumatic reaction of the intervertebral joints, relieving and improving the pressure state of the intervertebral space, increasing the supporting role of the neck, reducing continued injury and strain, and conducive to the subsidence and recovery of tissue edema. The repair of damage can also consolidate the curative effect and prevent recurrence. ...

AI Technical Summary

Problems solved by technology

[0004] 1. Most of the existing neck braces and other fixing devices are pasted and fixed with the Velcro structure of the restraint belt. Repeated disassembly is easy to loosen and it is troublesome to wear, which cannot meet the needs of patients.

[0005] 2. Existing neck braces and other fixed devices cannot be made according to individual differences, so the suitability and comfort are poor, and long-term wearing increases the pain of patients

[0006] 3. The existing fixed devices such as neck braces are not reliable because they are general-purpose, heavy and expensive
