Surgical needle for a surgical system with optical recognition
First Claim
Patent Images
1. A system for image-guided surgery comprising:
- an imaging probe;
a medical tool comprising a tip, wherein the medical tool includes an optically detectable non-repeating pattern extending along a sufficient portion of said tool such that at least a portion of said optically detectable non-repeating pattern remains visible outside of a patient during surgery so as to allow a position of the tip to be determined based on said visible portion;
a visual imaging system in communication with the imaging probe, the visual imaging system comprising a plurality of light-sensitive devices to be arranged outside of the patient, the light-sensitive devices being configured to generate an input and detect said portion of said optically detectable non-repeating pattern that is visible outside of said patient during surgery based on said input, the visual imaging system being configured to resolve the optically detectable non-repeating pattern to identify the medical tool and to track the medical tool; and
a display configured to display an image from the imaging probe and to overlay a real-time representation of the medical tool and tracking information over and registered to said image including the position of the tip, based on the resolved pattern, regardless of whether the tip is obstructed or visible.

Abstract
A system for image-guided surgery may include a visual imaging system, a medical tool comprising a shaft and a tip, wherein the shaft of the tool includes an optically detectable feature that allows a position of the tip to be determined, and a display configured to display a real-time representation of the medical tool including the position of the tip regardless of whether the tip is obstructed or visible.

16. A method for image guided surgery comprising:
-
receiving, by one or more processors, input from one or more light-sensitive devices mounted on an imaging probe and arranged outside of a patient, the input being based on light reflected from a tool, wherein the tool includes an optically detectable non-repeating pattern extending along a sufficient portion of said tool such that at least a portion of said optically detectable non-repeating pattern remains visible outside of a patient during surgery; detecting, by the one or more processors, the optically detectable non-repeating pattern extending along the tool based on said input from one or more light-sensitive devices; identifying, by the one or more processors, the tool based on the optically detectable non-repeating pattern; tracking, by the one or more processors, the tool based on the portion of said optically detectable non-repeating pattern that remains visible outside of said patient during surgery; calculating, by the one or more processors, one or more candidate tip locations in a three dimensional space using the portion of said optically detectable non-repeating pattern that remains visible outside of said patient during surgery; receiving, by the one or more processors, images from the imaging probe; and displaying, by the one or more processors, output from the imaging probe and overlaying a real-time representation of the tool and an insertion depth of the tip and the one or more candidate tip locations. - View Dependent Claims (17, 18, 19)
