ABSTRACT:
The present invention relates to a system and a method of manufacturing a porous bio-implant having a connecting member integrally formed therewith, and more particularly, to a system and a method of manufacturing a porous bio-implant in which a connecting member is integrally formed by sintering a metal powder by a high voltage instant discharge in the state that the connecting member is inserted in a pyrex tube and then the metal powder is put in the pyrex tube. A system of manufacturing a porous bio-implant having a connecting member formed integrally therewith includes a power supply supplying a low voltage; a voltage booster for boosting the low voltage supplied from the power supply to a high voltage; a condenser charging the high voltage boosted by the voltage booster through a switch; a vacuum switch for instantaneously discharging the high voltage charged in the condenser; and a bio-implant manufacturing apparatus for manufacturing a bio-implant by the high voltage discharged instantaneously from the vacuum switch.
