Surgical navigation system with one or more body borne components and method therefor

Abstract

A system for performing a navigated surgery comprises a first target attached to a patient at a surgical site and a second target at the surgical site. An optical sensor is coupled to the user and detects the first target and second target simultaneously in a working volume of the sensor. An intra-operative computing unit (ICU) receives sensor data concerning the first target and second target, calculates a relative pose and provides display information. The sensor can be handheld, body-mounted or head-mounted, and communicate wirelessly with the ICU. The sensor may also be mountable on a fixed structure (e.g. proximate) and in alignment with the surgical site. The ICU may receive user input via the sensor, where the user input is at least one of sensor motions, voice commands, and gestures presented to the optical sensor by the user. The display information may be presented via a (heads-up) display unit.

AI Technical Summary

Benefits of technology

The patent describes a system and method for performing a navigated surgery using a sensor and an intra-operative computing unit (ICU). The sensor detects targets attached to a patient at a surgical site and the ICU calculates the relative position of these targets. The system can provide display information to a user through a heads-up display or other display unit, and can also receive user input through the sensor. The technical effects of this system include improved precision in surgery and reduced risk of complications.

Problems solved by technology

The binocular cameras are part of large and expensive medical equipment systems.

There are several limitations to existing binocular-based navigation systems, including line-of-sight disruptions between the cameras and the objects, ability to control computer navigation software, cost, and complexity.
