Customized personalized 3D printing simulated prosthetic finger

Abstract

The invention discloses a customized personalized 3D printing simulated prosthetic finger. A method includes the following steps of information collection and three-dimensional reconstruction, printing of a planting body, planting of the planting body, three-dimensional reconstruction of the simulated prosthetic finger and mounting of the prosthetic finger. Determining of a planting nail and making of the customized physiological simulated prosthetic finger are realized through three-dimensional image technology, and needs on functions and appearance of a patient are met. Raw materials and operation are advanced, scientific, simple and practical, convenience is brought to mounting of a wound finger, and the objective of saving cost can be achieved when compared with oral implantology. Trauma to the patient is minimal, operating time is short, and personalized treatment effect is obvious.

Description

technical field [0001] The invention relates to an implant prosthesis, in particular to a customized personalized 3D printed artificial prosthetic finger. Background technique [0002] my country is a developing country, with the rapid development of industry, agriculture and transportation, a large number of patients with hand trauma have emerged. In Heilongjiang province alone, the number of hand injuries can reach 50,000 per year, among which injuries to the distal joints of the fingers are the most common. By analogy, there are about one million patients with finger injuries every year, and dozens of them need implant prosthesis repair. This is a huge market. Since the 1980s and 1990s, labor-intensive industries have developed rapidly in China. If the average annual hand injury is 500,000, the number of people who have installed finger injuries is 300,000 per year. , the group is conservatively estimated to exceed 5 million. If the conversion rate is 50%, the per capita...

AI Technical Summary

Problems solved by technology

Wearing a highly simulated finger prosthesis can improve the appearance of the patient's incomplete fingers to a certain extent, but because most of the finger prostheses currently on the market are made of soft silicone materials, they are only for decoration and cannot greatly improve the patient's hand function.

[0005] With the maturity of oral implant technology, some doctors carry out clinical work of finger implant prosthesis, all of which use dental implant prosthesis. From the perspective of appearance, biomechanics and physiology, it is not completely suitable for the tubular bone of the finger, so it cannot achieve Ideal requirements for improving hand function and appearance
