Abstract: An apparatus includes a counter top sized outer case; first and second electric motors disposed inside of the case. A positive displacement liquid pump with a pulsating output is operatively connected to said first electric motor and has an input and output port. A positive displacement gas pump with a pulsating output is operatively connected to the second electric motor and has an input and output port. A liquid source is fluidly connected to the input port of the liquid pump. The method further includes connecting a medical line or instrument to be cleaned to the output port of the liquid pump and operating the pump until the line or instrument has been cleaned. The line or instrument is then disconnected and connected to the output line of the gas pump. The gas pump is operated until the line or instrument has been cleared of liquid and then disconnected.

Abstract: A multi-function surgical instrument for facilitating ophthalmic surgery of the eye (3) by laser means, included are a lower ring (1) and an upper ring (2). One or two intermediate rings may also be included. The lower ring (1) includes a central aperture (11) to capture the limbus and aid in positioning of the eye (3). Protuberances on the lower surface (18) of said ring (1), application of vacuum between the lower surface (18) of the ring (1) and the eye (3), or both may be used to more firmly grip the eye (3). Ports (14) disposed on the upper surface (13) of the lower ring (1) and connected to a vacuum source may be used to control hydration of the surgical field. Attached to structures of the lower ring (1) is a sterile platform (17) for reposing temporarily removed tissues (32) during the administration of laser pulses to other tissues. The upper ring (2) is disposed above the surgical bed.

Abstract: A method and system for laser surgery produces controlled laser pulses and simultaneously verifies that a correct sequence of pulses are being delivered to the patient. A photo detector receives a predetermined portion of the energy of the treatment pulses as they exit the system. A separate monitoring computer compares an output signal from the photo detector with reference information for the treatment sequence. The system is exemplified in an implementation in an ophthalmic laser surgery system.

Abstract: The multi-function surgical instrument for facilitating corneal surgery by laser includes lower and upper rings. Lower ring includes a wall structure about a central aperture. Wall of the lower ring isolates a cornea disposed within the central aperture. Drainage system of the lower ring is used to control hydration of corneal tissue disposed in the central aperture. Platform of the lower ring isolates and prevents excessive hydration of a corneal flap reposed thereon. Upper ring includes a plurality of passages having directed ports and may be used to evacuate plume, direct beneficial fluids or gases onto tissues below.

Abstract: A method and system for laser surgery produces controlled laser pulses and simultaneously verifies that a sequence of pulses of prescribed energy are being delivered to the patient. A photo detector receives a predetermined portion of the energy of each treatment pulse. A separate monitoring computer compares an output signal from the photo detector corresponding to each treatment laser pulse with a reference value for that type of pulse obtained in a calibration sequence. Implementation in an ophthalmic laser surgery system is also disclosed.
