Abstract
Various systems and methods of controlling a surgical visualization system and controlling devices according to the displayed point of view of the surgical visualization system are disclosed. The visualization system can allow users to change, update, or manipulate the displayed visualization utilizing overlapping or multiple images. Further, the controls and/or display screens of surgical instruments coupled to the visualization system can be adjusted to correspond to the orientation of the surgical instrument as visualized by the visualization system.
Claims19
A control system for a handheld surgical instrument comprising a user control, the control system comprising:
- an imaging system, comprising:
- an emitter configured to emit electromagnetic radiation (EMR);
- and
- an image sensor configured to receive the EMR reflected from a surgical site;
- and
- a control circuit in signal communication with the imaging system and the handheld surgical instrument, wherein the control circuit is configured to:
- generate an image of the surgical site based on the EMR received by the image sensor;
- define a first coordinate system with respect to the surgical site according to the image;
- receive a second coordinate system defined by the handheld surgical instrument;
- determine a transfer function to translate a coordinate in the second coordinate system to the first coordinate system;
- and
- provide the transfer function to the handheld surgical instrument to cause the handheld surgical instrument to adjust the user control according to the transfer function.
A control system, comprising:
- an imaging system configured to capture a live feed of a surgical site from a first point of view, wherein the imaging system comprises:
- an emitter configured to emit structured electromagnetic radiation (EMR);
- and
- an image sensor configured to receive the structured EMR reflected from the surgical site;
- a display screen;
- and
- a control circuit communicatively coupled to the imaging system and the display screen, wherein the control circuit is configured to:
- generate a first image of the surgical site based on the structured EMR received by the image sensor;
- receive a second image of the surgical site;
- align the first image and the second image;
- generate a three-dimensional representation of the surgical site based on the first image and the second image as aligned;
- display the live feed of the surgical site from the first point of view on the display screen, wherein the live feed is displayed with a first visual characteristic;
- receive a user selection to manipulate a point of view of the surgical site;
- and
- according to the user selection, update the point of view as displayed on the display screen from a first state, in which the live feed of the surgical site from the first point of view is displayed on the display screen with the first visual characteristic, to a second state, in which a second point of view of the surgical site is displayed on the display screen, wherein, in the second state, an out-of-sight portion of the surgical site from the first point of view is shown on the display screen, wherein the out-of-sight portion is displayed based on the three-dimensional representation of the surgical site, and wherein the out-of-sight portion is displayed with a second visual characteristic different than the first visual characteristic.
