  • Publication number: 20230310087
    Abstract: A navigation method and a navigation system for a surgical instrument are provided. The navigation method includes: setting a predetermined surgical path; measuring a position and an orientation of the surgical instrument through a positioning unit, in which the surgical instrument has a transmission mechanism and an operating end; measuring a stress condition of the operating end of the surgical instrument by a force sensor; calculating first deformation information, induced due to the stress condition, of the surgical instrument according to a force deformation model; calculating a compensation amount according to the first deformation information and the measured position and orientation of the surgical instrument; and adjusting the surgical instrument to a new position or orientation according to the compensation amount, so as to maintain the surgical instrument on the predetermined surgical path.

  • Patent number: 11612438
    Abstract: A navigation method for a medical operation and implemented by a robotic system is provided. The method includes the steps of: receiving, at a processor of the robotic system, at least one set of navigation data; receiving or generating at least one three-dimensional model of the virtual object in the navigation data; calculating the navigation data to generate a virtual environment and at least one navigation instruction; and presenting, at a user interface associated with the robotic system, the virtual environment and/or the navigation instruction to a user of the robotic system for the user to refer to during the medical operation.

  • Patent number: 11298186
    Abstract: A surgery assistive system includes an instrument having a tool and a manipulator connected to the tool, a spatial sensor system for detecting spatial information of the tool, and a computer system for manipulating a kinematic state of the manipulator. A method for obtaining surface information by the surgery assistive system includes the steps of: defining a target region and a plurality of reference points on a virtual anatomical model of a subject; prompting a user to generate sampling information by using the instrument to sample a plurality of sampling points on the subject corresponding to the reference points; and designating the sampling information as surface information of the sampling points. Each piece of the sampling information includes a coordinate of one of the sampling points, an angle of a contact of the tool at the sampling point, and parameters associated with the contact.
