Patent number: 11185373Abstract: A method for re-registration between a robotic coordinate system and an image data set is provided. The inventive re-registration method includes the steps of providing an image data set that has been registered within a robotic coordinate system based on an initial bone position; locating a first conserved point and a line segment that is fixed relative to the initial bone position prior to any detectable change in bone position from the initial bone position; relocating the first conserved point and at least a portion of the line segment after bone motion may have occurred to determine the locational change in the first conserved point and the line segment; and re-registering the image data set within the robotic coordinate system based on the determined locational changes. A system for performing this method is also provided.Type: GrantFiled: March 1, 2017Date of Patent: November 30, 2021Assignee: THINK SURGICAL, INC.Inventors: Nathan A. Netravali, Feimo Shen

Patent number: 10888337Abstract: Systems and methods for monitoring an operative site during a surgical procedure using a computer controlled surgical device. In general, the methods include the steps of processing one or more defined cutting paths having one or more cut regions; determining a correlation between the cut region and one or more critical regions to generate an alert, wherein the alert indicates a movable end-effector is within a defined proximity of the critical region; and requiring a user acknowledgment of the alert to allow processing of the cutting path to continue. Also described herein are systems and methods for minimizing user fatigue during a semi-computer controlled surgical procedure. In general, the methods includes the step of requiring a user generated acknowledgment in response to a computer generated alert, wherein the user acknowledgment is generated using a user controller, the user controller being minimally intrusive to the user experience.Type: GrantFiled: February 6, 2018Date of Patent: January 12, 2021Assignee: THINK SURGICAL, INC.Inventors: Feimo Shen, In K.

Publication number: 20200005666Abstract: A system and method are provided that permits a mentor to remotely observe, train, or mentor an end-user of a medical device. The remote mentor is able to observe and take control, if necessary, of a medical device during a surgical procedure from a remote location using a network connection. New end-users, or end-users requiring assistance, may obtain feedback directly from the mentor in real-time. The remote mentor may remove power from the medical device at any time to provide assistance or recommendations to the end-user. The remote mentor can then re-activate the power, or allow the device to re-power, after assessing the situation.Type: ApplicationFiled: November 7, 2017Publication date: January 2, 2020Inventors: Feimo SHEN, Peter NAKAMOTO, In K.

Publication number: 20120258418Abstract: A portable dental prophylaxis and bleaching system is provided for simultaneous tooth polishing and bleaching. It includes an oscillatory driving handpiece, a dental angle with a disposable rubber cup assembly, a dual-component dispenser, and a disposable mouthpiece. The battery-powered handpiece transforms a continuous rotation through a driving cam into a rotary oscillation which is then transferred through the attached dental angle to the rubber cup with an obtuse angle at its distal output end. The dispenser is operated manually to correctly apportion and mix the dual treatment materials into the rubber cup. In order to provide longer shelf life and effective bleaching action, the treatment materials are maintained at optimal pH values in separate compartments within the dispenser before use. The disposable mouthpiece is shaped for easy access to the user's teeth while protecting the gum surfaces. The system can be used both in dental clinics and at home.Type: ApplicationFiled: April 5, 2011Publication date: October 11, 2012Inventor: Feimo Shen
