摘要： A heart-synchronized pulsed laser system includes a laser; means for sensing the contraction and expansion of a beating heart to be synchronized with the laser; means, responsive to the means for sensing, for generating a trigger pulse; means for positioning the leading edge of the trigger pulse; means for positioning the leading edge of the trigger pulse during the contraction and expansion cycle of the heartbeat; means for defining the width of the trigger pulse to occur during the heartbeat cycle; and means responsive to the trigger pulse for firing the laser to strike the beating heart at the time indicated by the trigger pulse position and for the period indicated by the width of the trigger pulse. In addition, the invention feature a handpiece for a medical laser system comprising a barrel for having a passage for transmitting a laser beam and a contacting wall on one end of said barrel including an aperture in communication with the passage, a solid face extending radially outward from the aperture to the periphery of said contacting wall, and a knurled surface on the face for preventing movement of the contacting wall with respect to the heart wall during surgery.

摘要： A decoupled dual-beam control system for a compact micromanipulator unit for a surgical laser system includes a focusing mechanism for focusing a first laser beam of a first wavelength at a predetermined focal point; and a control mechanism for directing a second laser beam of a second wavelength onto the focusing mechanism; the control mechanism includes a device for varying the diameter and wavefront of the second laser beam at the focusing mechanism for enabling the focusing mechanism to focus the second beam in the same focal plane as the first beam. The control mechanism further includes a device for translating the second beam relative to the focusing mechanism for enabling the focusing mechanism to coincidentally position the foci of the surgical and aiming beams in the focal plane.
