End-effectors for surgical robotic systems having sealed optical components

A ruggedized auto-clavable end-effector for a surgical robot system, comprising:

• an end-effector body configured to guide a surgical instrument and adapted to attach to a robotic arm, the end effector including:
• an optical sub-assembly received in the end-effector body and including:
• a window that is transparent to a predetermined range of light radiation wavelengths;
• a gasket disposed below the window and between the end-effector body and the window to define an internal cavity of the end effector body;
• a retainer cover disposed over the window and compressing the gasket between the window and the end effector body to form a seal between the window and the end effector body;
• and
• a light emitter disposed in the internal cavity for tracking by an external navigation camera system, the light emitter configured to emit light in the predetermined range of light radiation wavelengths through the window;
• wherein an interior portion of the end effector body includes electronic components coupled to the light transmitter and the entire interior portion of the end effector body is free of any potting material.
