Description

technical field

[0001] The invention relates to a manufacturing technology of medical supplies, in particular to a device for manufacturing medical implants, in particular to a special laser selective melting device for directly manufacturing metal orthopedic implants. Background technique

[0002] At present, orthopedic implants, especially hip replacement, have become one of the fields with the largest investment and most prominent development in orthopedic surgery. According to statistics, there are 1.1 million hip implants in the world every year, and the trend is increasing year by year. Therefore, the research on metal orthopedic implant technology has important scientific value and social economic value.

[0003] The implanted prosthesis currently used in my country is mainly a series of standard parts imported from abroad. The imported products are designed for Caucasians. Measurement data show that there is a significant difference in the neck-shaft angle between ...
