Abstract
Techniques for enhancing awake brain surgery include a navigation system to track a pose of a surgical instrument relative to a pose of the target anatomy of a patient. A head-mounted device (HMD) is worn by the patient during surgery. A control system is in communication with the navigation system and the HMD. The control system registers one or more images with the target anatomy. The control system identifies a structure of the target anatomy based on the one or more images of the target anatomy. The control system detects the pose of the surgical instrument being proximate to the identified structure of target anatomy, and based on such, the control system controls the HMD to generate an output to provoke a response of the patient.
Claims20
A surgical system comprising:
- a navigation system configured to track a pose of a surgical instrument relative to a pose of a target anatomy of a patient;
- a head-mounted device (HMD) configured to be worn by the patient during surgery;
- and
- a control system in communication with the navigation system and the HMD, the control system configured to:
- register one or more images with the target anatomy;
- identify a structure of the target anatomy based on the one or more images of the target anatomy;
- detect the pose of the surgical instrument being proximate to the identified structure of target anatomy;
- and
- based on detection of the pose of the surgical instrument being proximate to the identified structure, control the HMD to generate an output to provoke a response of the patient.
A head-mounted device (HMD) for use with a navigation in awake brain surgery of a patient, the HMD comprising:
- a support structure to be worn by the patient during surgery;
- a display supported by the support structure and being visible by the patient;
- a speaker system supported by the support structure and being audible to the patient;
- one or more sensors supported by the support structure;
- and
- an HMD controller coupled to the display, speaker system, and one or more sensors, wherein the HMD controller is configured to:
- obtain an instruction from a navigation system in response to the navigation system detecting that a surgical instrument is proximate to a specific brain region of the patient;
- based on receipt of the instruction, control one or both of the display and the speaker system to generate an output to provoke a response of the patient;
- and
- utilize the one or more sensors to monitor the response of the patient and functionally evaluate the specific brain region.
