摘要:
In various embodiments, a handpiece may include an irrigation line coupled to an adjacent line reservoir with a piston configured to move within the adjacent line reservoir to increase an irrigation pressure in the irrigation line near a surgical site. In some embodiments, a sensor may be used to detect an occlusion break in the aspiration line and information from the sensor may result in signaling an actuator to move the piston in response to the occlusion break detection to compensate for a vacuum pressure drop associated with the occlusion break. The handpiece may further include a purge bypass line between the irrigation line and the adjacent line reservoir to allow flow from the irrigation line to travel through the adjacent line reservoir to purge the adjacent line reservoir.
