Title
(EN) SURGICAL INSTRUMENTS WITH SENSORS FOR DETECTING TISSUE PROPERTIES, AND SYSTEMS USING SUCH INSTRUMENTS
(FR) INSTRUMENTS CHIRURGICAUX DOTES DE CAPTEURS DESTINES A DETECTER DES PROPRIETES TISSULAIRES ET SYSTEMES UTILISANT CES INSTRUMENTS
Abstract
(EN)



A system is provided that furnishes expert procedural guidance based upon
patient-specific data gained from surgical instruments incorporating sensors
on the instrument's working surface, one or more reference sensors placed
about the patient, sensors implanted before, during or after the procedure,
the patient's personal medical history, and patient status monitoring
equipment. Embodiments include a system having a surgical instrument with a
sensor for generating a signal indicative of a property of a subject tissue of
the patient, which signal is converted into a current dataset and stored. A
processor compares the current dataset with other previously stored datasets,
and uses the comparison to assess a physical condition of the subject tissue
and/or to guide a procedure being performed on the tissue.
