Abstract
A method and system provide a surgical hand piece including an aspiration line, a tip and a sensor. The tip is coupled with the aspiration line. The sensor is in the aspiration line. The sensor measures a change in at least one of flow through the aspiration line, pressure in the aspiration line and motion of an additional portion of the hand piece within the aspiration line.
Claims15
A surgical hand piece, comprising:
- an aspiration line;
- a sensor residing in the aspiration line, the sensor for measuring a change in velocity of a piston of the surgical hand piece within the aspiration line, wherein the sensor is selected from a Hall effect sensor, a Hall effect encoder, an accelerometer, and an optical motion sensor;
- and
- a tip coupled with the aspiration line.

A surgical hand piece, comprising:
- an irrigation line;
- an aspiration line;
- a piston residing in the aspiration line;
- a motion sensor residing in the aspiration line, the motion sensor for measuring a change of at least one hundred percent in speed of the piston within the aspiration line, the motion sensor being selected from a Hall effect sensor, a Hall effect encoder, an accelerometer, and an optical motion sensor;
- and
- a tip coupled with the aspiration line and the irrigation line, a portion of the tip being configured to be inserted into a patient's eye, the motion sensor providing a signal in response to the change and wherein a vacuum source is controlled to reduce a vacuum in response to the signal.
