Surgical instruments with sensors for detecting tissue properties, and system using such instruments
First Claim
1. A system comprising:
- a surgical instrument having a sensor configured to generate a signal indicative of a property of a subject tissue of a patient;
a signal processor configured to receive the signal and convert the signal into a current dataset;
a memory configured to store the current dataset; and
a processor configured to determine a relationship between the current dataset and datasets of signals indicative of the property of a subject tissue of other patients previously stored in the memory, to determine a weighting factor based on the determined relationship between the current dataset and the previously stored datasets, and to interpolate or extrapolate a physical condition of the subject tissue or guide a current procedure being performed on the subject tissue based on the determined weighting factor and outcomes of the other patients previously stored in the memory,wherein the processor is further configured to predict the likelihood of success of the current procedure being performed on the subject tissue based on the weighting factor and the outcomes of the other patients previously stored in the memory.

Abstract
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.
