The invention relates to a device (1) for use in eye surgery, comprising a container (9) with fluid (5) which is connected via an irrigation line (12) to a surgical handpiece for delivering the fluid (5) for rinsing an eye (3) on which surgery has been performed, wherein a pillar (8), which in particular is electrically adjustable in its height, is provided for supporting the container (9) and for adjusting the height (H) between the container (9) and the surgical handpiece, and wherein a control for adjusting the height of the pillar (8) is provided in order to deliver the fluid (5) from the surgical handpiece into the eye (3) at an irrigation pressure predetermined by the surgeon, wherein pressurizing means (10) are provided which are designed for charging the fluid (5) to be delivered from the container (9) to the irrigation line (12) with an atmospheric overpressure (P.sub.AT) and wherein the control for adjusting the desired irrigation pressure is designed both for adjusting the height (H) of the pillar (8) and for adjusting the atmospheric overpressure (P.sub.AT) to be charged.

Vacuum motor for operation of a lavage system
09861770 · 2018-01-09 · ·

A vacuum motor comprising a working plunger, an internal space, in which the working plunger is arranged such that it is mobile in linear direction, a resetting element that exerts, at least for part of the time, a force on the working plunger that acts in the direction of a front side of the internal space, a gas inlet opening for supplying ambient air or a compressed gas into the internal space, and a gas outlet opening for discharging the gas from the internal space. The gas outlet opening is connectable to a negative pressure source, whereby a control plunger is arranged between the working plunger and a rear side of the internal space such as to be mobile in linear direction in the internal space. The control plunger is supported as in a bearing such as to be mobile with respect to the working plunger, and a catch element and/or a spacer is arranged on said working plunger and/or control plunger, whereby the catch element, upon a motion of the working plunger towards the front side of the internal space, transfers the control plunger into the first position, and whereby the catch element or the spacer, upon a motion of the working plunger towards the rear side of the internal space, transfers the control plunger into the second position.

Automatic irrigation-coordinated lithotripsy
12161289 · 2024-12-10 · ·

Systems and methods for controlling an energy output setting of a lithotripsy device during a lithotripsy procedure are provided. The system includes a laser or other lithotripsy device configured for facilitating the lithotripsy procedure, an irrigation system configured for supplying an irrigant such as saline to a surgical site, and a temperature sensor configured to provide temperature data associated with the irrigant. The system can modulate the energy output setting of the lithotripsy device based on an estimated temperature that is determined based at least in part on the temperature data and one or more other factors such as a current energy output setting or a flow rate of the irrigant.

Irrigation system for an ultrasonic surgical handpiece

An ultrasonic surgical handpiece includes a motor having a transducer assembly along a central axis of the surgical handpiece. The motor is configured for operative connection to a power source. A surgical attachment has a proximal end detachably connected to the motor and a distal end defining a working plane for engagement with biological tissue. A housing has a housing distal end, a housing proximal end, and a cavity configured to receive the motor and the surgical attachment. An irrigation path of the housing is configured to communicate irrigation fluid. The irrigation path has an inlet proximate the housing proximal end operatively connected to an irrigation fluid source, and an outlet proximate to the working plane. The irrigation path is separated from the housing cavity to prevent contact between the irrigation fluid and an operational portion of the surgical attachment.
