MEDICAL ROBOT DRIVING SAFETY FOR MULTIPLE SAFETY APPARATUS

摘要

The present invention relates to a multi-safety device for securing driving safety of a medical robot, which is able to secure a high driving reliability and safety in the instrument via a multi-safety device connected in a series. The multi-safety device according to the present invention comprises the followings in a series: an instrument unit (100) consisting of a power input safety check device (110) for detecting a malfunction of a power input device of a motor (111), a power output safety check device (120) for detecting a malfunction of the output terminal of a reducer (121), a power delivery unit safety check device (130) for detecting validity of the process of delivering the driving power between the input unit and the output unit, an input terminal control device (140) in the power output, and an output terminal control device (141) in the power output; a control unit (200) having a controller (201) operated by a power supply (202) so as to control a medical robot with a delivered signal of the instrument unit (100); a switching unit (300) connected between the control unit (200) and the instrument unit (100), and switched so as to deliver signals to the control unit (200) according to detecting signals of safety check (S1, S2, S3) of the instrument unit (100); and an emergency stopper (210) for stopping the medical robot according to the signal of the control unit (200).
