Medical research

Medicine has always been at the forefront of technology. The emergence of various new technologies has relieved humans from physical pain, compensated for physical disabilities, and helped patients return to a normal life.

In the field of personalized customization of medical rehabilitation equipment and prostheses, traditional contact limb data acquisition methods can no longer meet the needs of modern medical treatment in terms of accuracy and efficiency, and three-dimensional scanning technology solves this problem.

A three-dimensional scanner is a non-contact scientific instrument used to detect and analyze the shape (geometric structure) and appearance data (such as color, surface albedo, etc.) of objects or environments in the real world. The 3D scanner has the characteristics of fast scanning speed and high accuracy.

Solution

This time, we scanned the design prototype shell of the prosthesis.

1.Stick anchor points

Stick the reflective mark points, the principle of positioning and splicing of the scanner is to scan and splice the reflective mark points. When pasting points to the parts of the prosthesis that need to be scanned, stick points to the transition surface according to different parts.

2.Dismantle the prosthesis

Dismantle the entire prosthesis, and scan each part one by one (shown in the figure below)

3.Scan the prosthesis

Use a handheld laser 3D scanner to scan the shell of the prosthesis, and the details can be used for fine scanning.

4.Data processing

The software can automatically spliceand eliminatethe impurity of the platform. Finally, you can quickly output asc, stl, obj, ply, txt and other file formats. The highest resolution can reach 0.02mm, so the subtle features can be scanned perfectly and the real model can be completely restored.

Finally, combined with 3D printing technology, the time of making a limb model can be shortened to only two hours, which greatly shortens the cycle of prosthetics. Effectively improve accuracy, help companies improve efficiency, and make patients more comfortable to wear. The shell of prosthetic mode made by the three-dimensional scanning technology can make the prosthetic body more realistic. Help patients reduce their burden, integrate into society faster, and enrich their confidence in life.
