Abstract: A system detects whether a pneumatic surgical instrument is attached to a surgical system. A drive valve has an input for connection to a source of pressurized air, an output for connection to the surgical instrument, and an exhaust for exhausting pressurized air during operation of the surgical instrument. A pressure transducer in communication with the exhaust senses a pressure profile of air flow from the exhaust. A first sensed pressure profile indicates that the surgical instrument is connected to the output and a second sensed pressure profile indicates that the surgical instrument is not connected to the output. A detection circuit connected to an output of the pressure transducer detects whether the surgical instrument is attached to the surgical system based on the sensed pressure profile.

Abstract: An ophthalmic instrument 10 for providing illumination to a surgical site, includes a housing 12 defining an internal volume 14, at least one pathway 16 extending through the internal volume of the housing to external of the instrument that is designed for irrigation or aspiration during surgery, and a fiber optic component 18 positioned within the at least one pathway 16 for providing illumination to a surgical site. A modified aspiration tube 300, includes aspiration tubing 350 with an internal volume 360 and a fiber optic component 318 spliced within internal volume 360.
