In various embodiments, a surgical console may include a sensor strip with sensor strip sensors (e.g., field effect or capacitive sensors) offset vertically and configured to receive an input from a user corresponding to a vertical height of a patient's eyes relative to the surgical console. The surgical console may use the input from the sensor strip to determine a patient eye level (PEL) relative to a surgical console component and then use the PEL and the at least one component in controlling operation of at least one of a source of irrigation or a source of aspiration during an ophthalmic procedure. The surgical console may further include a plurality of visual indicators positioned relative to at least two of the plurality of sensor strip sensors and configured to be illuminated to correspond to a sensor detecting the touch input.

In various embodiments, a braking system may include an actuator, a pawl gear coupled to the actuator, and a wheel gear plate. The braking system may further include a brake pad, an outer wheel coupled to the brake pad, and a spring washer plate configured to press the wheel gear plate against the brake pad such that the wheel gear plate is configured to inhibit rotation of the outer wheel through friction between the wheel gear plate and the brake pad when the pawl gear inhibits rotation of the wheel gear plate. In some embodiments, the braking system may further include a sensor and the actuator may be triggered to actuate the pawl gear in response to signals from the sensor.

A graphical user interface for use in an ocular surgical system, such as phacoemulsification and vitreo-retinal surgical systems. A display screen shows a display element that includes a representation of a parameter of pulses generated by the ocular surgical system relative to a position of the controller. A window is displayed on the display screen and generated in response to touching the display screen of the ocular surgical system. The window includes a display element having a value of a parameter of the system. A value of the parameter is changed by touching the display screen at the adjustment element. The window can also include a representation of the parameter of the pulses relative to the position of the controller and an adjustment element for changing a value of the parameter represented in the display element. The representation in the window can be linear or non-linear, indicating the function of the parameter relative to a position of a controller, such as a foot pedal. A current representation of the parameter displayed in the window is changed to a different representation of the parameter in response to touching the display screen at the window. The window is closed by touching the display screen at a pre-defined area of the window. The window can also be configured to fade away or close after a pre-determined amount of time of inactivity or in response to a user.

In various embodiments, a pressure sensor may be configured to detect pressure information associated with pressure in an eye during an ophthalmic surgical procedure. The pressure information may be wirelessly communicated, through a transmitter coupled to the pressure sensor, to a receiver communicatively coupled to a surgical console. The receiver may provide the received pressure information to the surgical console to use in controlling pressure at a surgical site during the surgical procedure. For example, controlling the pressure may include maintaining a desired IOL pressure level within the surgical site at the eye. In some embodiments, the pressure sensor may include a strain gage coupled to a contact lens or a sleeve of an ocular surgical handpiece. Other pressure sensor configurations are also contemplated.
摘要:
A surgical system that is able to sense the onset of an occlusion or other surgical event as well as when an occlusion breaks. To help avoid overheating of the tip, the system of the present invention predicts the temperature of the eye using irrigation flow rate and reduces the power to the handpiece automatically if an overheating situation is predicted. Alternatively or in addition, the system of the present invention monitors the power drawn by the handpiece, which is indicative of the cutting load on the tip, and automatically adjusts the power or stroke of the tip to compensate for increased loads on the tip.

A surgical system that is able to sense the onset of an occlusion or other surgical event as well as the instant an occlusion breaks. To help avoid overheating of the tip, the system determines an approximate temperature of the eye using an irrigation flow rate and reduces the power to the handpiece automatically if an overheating situation is predicted. Alternatively or in addition, the system monitors the power drawn by the handpiece, which is indicative of the cutting load on the tip, and automatically adjusts the power to the tip to compensate for increased loads on the tip.

A handpiece having a single set of piezoelectric elements polarized to produce longitudinal motion when excited at the relevant resonant frequency. The piezoelectric crystals are connected to an ultrasonic horn to which a cutting tip is attached. The horn and/or the cutting tip contains a plurality of diagonal slits or grooves. The slits or grooves produce optimized torsional movement in the cutting tip when the piezoelectric crystals are excited at a second resonant frequency. Preferably, the two drive frequencies are not coincident, but provided in non-overlapping pulses.

Embodiments of systems and methods for a simplified interface are disclosed. More specifically, embodiments of modes of interaction with a surgical console may be provided such that these modes of interaction limit or curtail the range of functionality which may be adjusted. In particular, certain embodiments may present one or more interfaces for user interaction which allow a user to select from a set of preprogrammed options, where the interface or the set of preprogrammed options may correspond to the mode in which a user is interacting with the surgical console. Each of these preprogrammed options may correspond to settings for one or more parameters such that by selecting a preprogrammed option the surgical console is configured according to these settings.
