Special laser selecting area melting equipment for directly manufacturing metal orthopedics implant

Abstract

The invention discloses special laser selecting area melting equipment for directly manufacturing a metal orthopedics implant. The equipment is characterized by comprising a forming system, a powder recovery system, a powder paving system, a laser transmission system, a dust filter and water / oxygen purification double-circulation system, and a sealing cavity; the forming system, the powder recovery system and the powder paving system are all positioned in the sealing cavity; the laser transmission system is positioned at the upper part of the sealing cavity; the dust filter and water / oxygen purification double-circulation system is positioned out of the sealing cavity; the forming system includes a forming cylinder, a forming cylinder piston, a ball screw, a servo motor and a grating ruler; a heating copper plate, a water cooling system and a temperature sensor are arranged in the forming cylinder piston; the powder paving system paves powder by an upper powder paving mode; and the forming process is performed under argon protection, and is provided with the dust filter and water / oxygen purification double-circulation system. The equipment is high in atmosphere cleanness of the forming cavity and high in forming part size precision, can form such bionic structures as porous structures and biological channels, and is suitable for quick and personalized customization of artificial hip joints.

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 ...
