Abstract
Systems, instruments, and methods are provided verifying the surgery is being performed in accordance with a surgical plan, wherein a surgical tool having a sensor outputs a data signal that enables the trajectory of the surgical tool to be displayed as an overlay on an image of an anatomical portion of a patient and a visual or audible signal that confirms the surgical tool is penetrating the anatomical portion in accordance with the surgical plan and/or that issues an alert indicating that the surgical tool is not being inserted into the anatomical portion according to the surgical plan.
Claims20
A surgical system for executing a surgical plan of penetrating an anatomical portion, the surgical system for use in conjunction with an imaging system, the surgical system comprising:
- a surgical tool having a cutting tip configured to penetrate the anatomical portion and a sensor to measure an electrical characteristic of the anatomical portion;
- a guidance system coupled to the imaging system and the surgical tool, wherein the guidance system is configured to:
- receive the surgical plan, the surgical plan identifying a specified orientation, trajectory and depth for penetration of the anatomical portion;
- receive and display images from the imaging system of the anatomical portion;
- receive sensor data from the sensor during penetration of the anatomical portion, wherein the sensor data corresponds to an electrical characteristic of the anatomical portion;
- determine whether the sensor data corresponds to the surgical plan;
- and
- display an indication of the orientation, trajectory and depth of the surgical tool as an overlay on the images of the anatomical portion,
- wherein the guidance system further is configured to continuously update the overlay of the indication of the orientation, trajectory and depth of the surgical tool on the display and to adjust real-time registration of the indication of the orientation, trajectory and depth of the surgical tool in the overlay responsive to the sensor data.
A surgical system for use with an imaging system, the surgical system comprising:
- a surgical tool having a sensor to measure electrical characteristics of an anatomical portion;
- a guidance system coupled to the imaging system and the surgical tool, wherein the guidance system is configured to:
- receive a surgical plan that identifies a specified orientation, trajectory and depth for penetration of the anatomical portion, the surgical plan including a variation in an expected electrical characteristic of the anatomical portion to be encountered during execution of the surgical plan;
- receive from the imaging system and display real-time images of the anatomical portion;
- receive sensor data from the sensor during penetration of the anatomical portion, the sensor data corresponding to a measured electrical characteristic of the anatomical portion;
- determine whether the sensor data corresponds to the surgical plan by comparing the measured electrical characteristic to the expected electrical characteristic;
- and
- display an indication of the orientation, trajectory and depth of the surgical tool as an overlay on the images of the anatomical portion,
- wherein the guidance system further is configured to continuously update the overlay of the indication of the orientation, trajectory and depth of the surgical tool on the display and to adjust real-time registration of the indication of the orientation, trajectory and depth of the surgical tool in the overlay responsive to the sensor data.
