Abstract:
PROBLEM TO BE SOLVED: To provide a system and method for identifying a component, such as an optical probe or pneumatic scissors, of an ophthalmic surgical device.SOLUTION: The component of the surgical device includes an identifier, such as an RFID tag 102. Data 104 from the RFID tag is transmitted to a RFID reader 112 of the device. A controller 115 determines whether the component corresponding to the received data can be used with the surgical device based on criteria, such as whether the received data is an authorized code that matches data stored in memory 114 or whether the received data solves or satisfies an algorithm. The authorized codes are selected from a larger set of available codes. The controller enables or disables the operation of the device with the component based on whether the criteria is satisfied, the number of uses of the component, an amount of time that has passed since the component has been used, or a geographic location.

PROBLEM TO BE SOLVED: To provide a reliable footswitch that functions to communicate with a surgical system while avoiding potential hazard or a restrictive environment created by entangled cables.SOLUTION: The surgical footswitch includes a base, a pedal, an encoder assembly, a wireless interface, and an internal power generator, and includes a first switch and a second switch. The wireless interface sends control signals from an encoder to a surgical controller and then instructs surgical equipment based on the control signal. This wireless interface eliminates the tangle of wires or tethers, which may be a hazard in a surgical theater. The internal power generator converts footswitch movement into stored energy, in order to eliminate potential failures of the footswitch during a surgery and to overcome the need to replace batteries of the footswitch.

PROBLEM TO BE SOLVED: To provide a reliable footswitch that avoids potential hazards or a regulated environment formed by a tangled cable and simultaneously functions to work on a surgical system.SOLUTION: The present invention provides a surgical footswitch that includes a base, a pedal, an encoder assembly, a wireless interface, and an internal power generator. The wireless interface passes a control signal from the encoder to the surgical console, which then directs the surgical apparatus based on the control signal. This wireless interface eliminates the tangle of wires or tethers, which may be a hazard in the surgical theater. The internal power generator translates footswitch movement into stored energy to eliminate potential failures of the footswitch during a procedure and overcome the need to replace batteries within the footswitch.

Abstract:
PROBLEM TO BE SOLVED: To provide even and parallel light curtain to solve the problem wherein a linear light source of high-resolution optical liquid level for continuous monitoring of a system generally uses high-diffusion LED array, in order to achieve even light intensity, as a result, it will have a very large visual angle that the rays, i.e., light beams no longer become parallel. SOLUTION: The point source is located on focal point of parabolic reflector to illuminate the parabolic reflector. The parabolic reflector reflects light from the point source to generate parallel light curtain. This parallel light curtain becomes parallel to the symmetric axis of the parabolic reflector, to illuminate ophthalmic surgery chamber for storing fluid. Sensor array, combined with the chamber, detects the parallel light curtain for illuminating the chamber and supplies an output to a sensing, processing, control system in order to determine the liquid level of the chamber. This optical method for determining the liquid level of surgical fluid has the advantage of preventing surgical fluid from physical contamination. COPYRIGHT: (C)2008,JPO&INPIT

Abstract:
System and method for identifying a component, such as an optical probe or pneumatic scissors, of an ophthalmic surgical device. A component of a surgical device includes an identifier (102), such as a RFID tag. Data from the RFID tag is transmitted to a RFID reader in the device. A controller (115) determines whether the component corresponding to the received data is operable with the surgical device based on criteria, such as whether the received data is an authorized code that matches data stored in memory or whether the received data solves or satisfies an algorithm. The authorized codes are selected from a larger set of available codes. The controller enables or disables the operation of the device with the component based on whether the criteria is satisfied, the number of uses of the component, an amount of time that has passed since the component has been used, or a geographic location. The RFID data can also be used to calibrate the surgical device for use with the particular component and for inventory and monitoring purposes.
Abstract:
A continuous high resolution fluid level monitoring system (300) is provided by embodiments of the present invention. This continuous high resolution fluid level monitoring system includes a unique fluid level sensor having a point light source (202), parabolic reflector (204), sensor array (308), and detection, processing and control system (310). The point light source illumines a parabolic reflector wherein the point light source is located at the focus of the parabolic reflector. The parabolic reflector reflects light from the point light source to produce a parallel light curtain (210). This parallel light curtain is parallel to an axis of symmetry of the parabolic reflector. The parallel light curtain illumines a chamber (302) such as a chamber in an ophthalmic surgical device used to contain surgical fluid (304). The sensor array coupled to the chamber detects the parallel light curtain illuminating the chamber. The sensor array provides an output to a detection/processing/control system in order to determine the fluid level within the chamber. This optical method of determining the surgical fluid levels may be advantageous in that it prevents physical contamination of the surgical fluids.
Abstract:
A filter and method for filtering an optical beam are disclosed. One embodiment of the filter is an optical filter for filtering an incident light beam, comprising an optically effective material characterized by: a light transmittance of less than 1% for wavelengths below 420 nm; and a light transmittance for wavelengths complimentary to wavelengths below 420 nm that, combined with the transmittance for wavelengths below 420 nm, will yield a filtered light beam having a luminosity of about 90% and an excitation purity of 5% or less. The complimentary wavelengths can be wavelengths above about 640 nm, wavelengths above about 660 nm, and/or wavelengths from about 540 nm to about 560 nm. Further, in one embodiment the difference between the light transmittance just below 420 nm and the light transmittance just above 420 nm can be greater than 90%. Above 420 nm, in some embodiments, the light transmittance can be arbitrarily determined. The optically effective material can be optical-grade glass, an optical-grade plastic or polymer, a thin-film dielectric coating, or an optical-grade glass or plastic coated with a dielectric coating. The optical filter can be mounted downstream of an illumination source exit aperture, wherein the illumination source produces the incident light beam, and upstream of a site to be illuminated by the filtered light beam. Alternatively, the optical filter can be operably mounted on a set of viewing optics of a surgical microscope to filter a reflected portion of a light beam produced by an illumination source and used to illuminate a site, such as a surgical site.
