Abstract: A robotic surgical system or simulator includes an input device, a display device, and a processing unit. The display device includes a representation of a surgical tool that is operably associated with the input device. The processing unit is in communication with the input device and is associated with the representation of a surgical tool to rotate the representation about a first axis of movement based on a scaled rotation of the input device about a first axis of rotation. In an aligned configuration, the input device is aligned with the representation about the first axis of rotation. When the input device is misaligned with the representation, the processing unit varies the scaled rotation of the input device to return the input device to the first aligned configuration until the input device is misaligned about the first axis of rotation a first predetermined offset from the aligned configuration.

Abstract: Apparatuses and methods are disclosed for applying laser energy having desired pulse characteristics, including a sufficiently short duration and/or a sufficiently high energy for the photomechanical treatment of skin pigmentations and pigmented lesions, both naturally-occurring (e.g., birthmarks), as well as artificial (e.g., tattoos). The laser energy may be generated with an apparatus having a resonator with the capability of switching between a modelocked pulse operating mode and an amplification operating mode. The operating modes are carried out through the application of a time-dependent bias voltage, having waveforms as described herein, to an electro-optical device (e.g., a Pockels cell) positioned along the optical axis of the resonator.

Abstract: Disclosed is a surgical instrument for cataract eye surgery. The instrument generally includes a handpiece that delivers sub-ultrasonic and ultrasonic vibrations in either a continuous emulsification mode or with on-off pulses that dynamically drive a hollow needle in either a pulsed fragmentation mode or a pulsed emulsification mode. The pulsed fragmentation mode is efficient at cutting lens tissue and the pulsed emulsification mode is efficient in emulsifying the cut lens tissue. The pulsed modes manage heat buildup from becoming excessive in the eye during the cataract surgery. While in the pulsed fragmentation mode, the hollow needle is never given the chance to vibrate at an established resonant frequency of the handpiece due to the short on-off period. In contrast, the pulsed emulsification mode has a long enough on-off period to permit an ultrasonic resonant frequency in the handpiece to develop, which drives the hollow needle at a higher energy than the pulsed fragmentation mode.

The distal portion of the distance indication member can be further configured to return to a non-deflected configuration when no longer in contact with the tissue surface.

Abstract: Systems and methods for stimulating the sensory cortex of an individual by obtaining a neuronal stimulation signal adapted to provide a movement cue for the individual and transmitting the neuronal stimulation signal to an electric contact of a neuronal stimulation electrode that is already implanted into the brain of the individual for a purpose different from providing the movement cue. Proprioceptive information is communicated to the individual by obtaining information about the body posture of the individual and applying a neuronal stimulation signal to an afferent axon targeting a sensory neuron in the cortex of the individual. The neuronal stimulation signal is determined based on the obtained body posture information and corresponds to the proprioceptive information. A first neuronal stimulation signal providing the movement cue and a second neuronal stimulation signal providing the proprioceptive information may be applied together to the cortex of the individual.

Abstract: A telesurgical system operates in a first operating mode and in a second operating mode. In the first operating mode, a moveable component is driven within a first range of an operating parameter. In the second operating mode, the moveable component is driven with a second range of the operating parameter, less than the first range. Usable instrument life is increased by decreasing mechanical degradation of the moveable component as a result of operating in the second range. A surgeon may select either operating mode.
