Abstract: A surgical control device includes a housing, a power source held within the housing, at least 1 switch mounted on a housing surface, and a transmitter held within the housing in communication with the switch. The device is for attachment to a surgical instrument, such that a user activates the switch by placing the switch and an opposing housing surface between a thumb and a finger and squeezing the thumb and finger towards each other, whereby the squeezing does not induce movement of the attached surgical instrument. The device transmits an activation signal from the switch to a remote controller for controlling a surgical function. The device also includes a removable attachment device for attaching the housing to the surgical instrument.

Abstract: A foot pedal assembly for remotely controlling an instrument is disclosed. The foot pedal assembly comprises a base member upon which a foot pedal is mounted. The foot pedal assembly also comprises a means for providing an optical transmitted signal for use in controlling the instrument in response to the movement of the foot pedal. The means for providing an optically transmitted signal comprises a plurality of individual light channels.

Abstract: An ultrasonic diagnostic scanner for obtaining ocular measurements is described. The ultrasonic diagnostic scanner generally comprises transmitter means for generating an ultrasonic signal, receiver means for receiving echo signals and for producing a peak signal at substantially the maximum amplitude of the echo signals when the echo signals exceed a predeterminable threshold level, programmable means for producing count signals indicative of the times between the transmission of the ultrasonic signal and the occurrence of a selected number of peak signals, and between the occurrence of predetermined peak signals, microcomputer means for controlling the transmitter and programmable means, and output means for generating a perceptible output indicative of the ocular parameter being measured. The ultrasonic diagnostic scanner also includes sensitivity adjustment means for maintaining a predetermined amplitude level of at least one of the echo signals under the control of the microcomputer means.
