US 12,527,599 B2 · System for a tissue resection margin measurement device

Abstract

Embodiments of the invention provide a system and method for resecting a tissue mass. The system for resecting a tissue mass includes a first sensor for measuring a signal corresponding to the position and orientation of the tissue mass. The first sensor is dimensioned to fit inside of or next to the tissue mass. The system also includes a second sensor attached to a surgical instrument configured to measure the position and orientation of the surgical instrument. A controller is in communication with the first sensor and the second sensor, and the controller executes a stored program to calculate a distance between the first sensor and the second sensor. Accordingly, visual, auditory, haptic or other feedback is provided to the clinician to guide the surgical instrument to the surgical margin.

Dependent claims

A system for determining a position and orientation of an instrument relative to a tissue mass disposed in or on an anatomical structure, the system comprising:

a deployment assembly comprising:
a needle cannula comprising a proximal end, a distal end, and a lumen extending therebetween;
a sensor assembly disposed in the lumen of the needle cannula, the sensor assembly comprising:
a fiducial tracker for providing a fiducial signal representative of a position of the fiducial tracker, the fiducial tracker comprising a distal end and a proximal end, the fiducial tracker being adapted to be secured in the anatomical structure in a vicinity of the tissue mass;
and
an electrical lead for providing electrical power to the fiducial tracker, the electrical lead extending distally from the distal end of the fiducial tracker towards the distal end of the needle cannula;
an instrument;
an instrument tracker for providing an instrument signal representative of a position and orientation of the instrument tracker, the instrument tracker being carried by the instrument;
and
a controller for determining the position and orientation of the instrument relative to the fiducial tracker.
