Surgical Energy

APPLICATION

In today’s robotic surgical cutting processes, knives are no longer in use. The modern manner of cutting is done by Electrosurgery which is a high-frequency (radio frequency) alternating polarity, electrical current.

This “Surgical Energy” is a new and challenging noise source that must be handled correctly by the sensitive servo system and especially by the high-level sensors.

As Netzer’s Capacitive Rotary Encoders are inherently designed for very noisy environments, the DS line of products was found to be immune to this challenging noise.

REQUIREMENTS

  • “Surgical Energy” immunity
  • Hollow shaft & low profile
  • High precision
  • BIT-Built In Test function
  • References in the field for a simple FDA approval

POSITION SENSOR

  • Netzer DS-16 and DS-40 Absolute Position Electric Encoder™ incorporated in the robotic arm and master/controller part of the robot
  • Compact, low profile, lightweight & wide bore: Allowing high-level integration for a low profile arm joint and controller design
  • Frame-less & contact-less with a negligible rotor weight: No mechanical parts operating, introducing no extra weight & inertia (load) to the system
  • Immune to magnetic interference: Can be very close to the frameless motor magnets
