First Claim
Patent Images
1. A system configured for medical operation comprising:
- a water jet device having an instrument drive mechanism;
an aspiration device separate from the water jet device; and
a robotic control system comprising a controller, a flow rate meter, a throttle valve, and a pump,wherein the flow rate meter is in communication with the controller and the controller is in communication with the pump and the throttle valve to form a feedback loop,wherein the flow rate meter is configured to generate and send a feedback signal to the controller,wherein the controller is configured to;
generate and send a control signal to the pump in response to the feedback signal, and generate and send a throttle control signal to the throttle valve to control a flow rate of the water jet device in response to the feedback signal,wherein the water jet device is configured to be coupled to the robotic control system via the instrument drive mechanism to generate a cutting jet based at least in part on the control signal from the controller so as to have a desired jet cutting area,wherein the flow rate meter is upstream from the instrument drive mechanism,wherein the aspiration device is configured to be coupled to the robotic control system to provide aspiration, andwherein the robotic control system is configured to operate the water jet device aspiration device, the flow rate meter, the throttle valve, and the pump to perform the medical operation according to a predetermined workflow.

Abstract
A water jet instrument may be used for manually performing eye surgery such as, cataract, or perform micro-surgery (remove cartilage), or any emulsification technique. The water jet instrument may be manually controlled or controlled by a system with a robotic control. The water jet apparatus defines a jet cutting area that is based at least in part on a flow rate meter and a feedback loop.
