The ultrasound transmitter is configured to generate and focus an ultrasound beam into a lens capsule of an eye of a patient, to emulsify a lens of the eye. The irrigation-aspiration tool having a distal end including an outlet of an irrigation channel for flowing irrigation fluid into the lens capsule, and an inlet of an aspiration channel for removing material from the lens capsule. The robotic arm is configured to move the distal end of the irrigation-aspiration tool inside the lens capsule. The processor is configured to control the ultrasound transmitter to irradiate one or more target locations in the eye capsule with the focused ultrasound beam, and control the robotic arm to move the distal end of the irrigation-aspiration tool in coordination with the target locations irradiated by the ultrasound transmitter.

Abstract: Phacoemulsification apparatus, consisting of a phacoemulsification probe having a distal end including a combination of a needle and a sleeve, the combination being configured for insertion into an eye of a patient, and being configured for fluid transfer between the eye and the combination. The apparatus has an ultrasound actuator configured to vibrate the needle, a first sensor configured to output a first indication indicative of physical contact between the needle and a lens of the eye, and a second sensor configured to output a second indication indicative of a parameter associated with the fluid transferred by the combination. A microcontroller is configured to receive the first and the second indication, to calculate a threshold for the first indication in response to the second indication, and to activate and deactivate the ultrasound actuator in response to the first indication crossing the threshold.

Abstract: A medical visualization apparatus includes two or more imaging devices, two or more robotic arms, multiple magnetic sensors coupled with the imaging devices, and a processor. The two or more imaging devices are configured to acquire images of an organ of a patient. The two or more robotic arms are configured to move the respective imaging devices. The multiple magnetic sensors are configured to output, in response to a magnetic field of a position tracking system, signals indicative of positions and viewing directions of the imaging devices. The processor is configured to estimate a position and a viewing direction of each of the imaging devices based on the signals, and, using the estimated positions and viewing directions, combine the images of the organ acquired by the imaging devices into a virtual reality (VR) image of the organ, and present the VR image to a user on a VR viewer.

Abstract: A pumping system for a phacoemulsification system, consisting of: a phacoemulsification probe, an irrigation tube providing irrigation fluid into an eye, an irrigation pump pumping the irrigation fluid, an aspiration tube conveying aspiration fluid from the eye, an aspiration pump pumping the aspiration fluid from the eye, an aspiration pump sensor providing a first signal indicating activation of the aspiration pump, and a pressure sensor providing a second signal indicating intraocular pressure (IOP) in the eye. A controller receives the first signal and second signals, and in response controls the irrigation pump to alter a registered flow rate of the irrigation fluid to a preset adjusted flow rate until a threshold, dependent on at least one of a time of operation of the irrigation pump at the preset adjusted flow rate and the second signal, is crossed. When crossed the irrigation fluid is pumped at the registered flow rate.

Abstract: A phacoemulsification system includes a phacoemulsification handpiece, an irrigation line and an aspiration line connected to the phacoemulsification handpiece, an Anti-Vacuum Surge (AVS) module inserted at least in the aspiration line, and a processor. The processor is configured to automatically detect whether an extension tubing is present in the aspiration line between the phacoemulsification handpiece and the AVS module, to set a first parameter setting, for detecting vacuum surges in the aspiration line, in response to detecting that the extension tubing is present, and, in response to detecting that the extension tubing is not present, to set a second parameter setting, different from the first parameter setting, for detecting the vacuum surges in the aspiration line.

Abstract: A system and method that includes inserting a needle of a phacoemulsification handpiece into an eye of a patient and vibrating the needle in a first trajectory. Matter from the eye is aspirated via an aspiration line while the needle is vibrated in the first trajectory. An indication is received, of a vacuum level in the aspiration line. Determined is, that the vacuum level has changed by at least a preset vacuum level change, and in response vibrating the needle is switched to a second trajectory, different from the first trajectory.
