US 2026/0144676 A1 · IDENTIFICATION OF ASPIRATED MATERIAL DURING SURGICAL PROCEDURES

Abstract

In certain embodiments, a method of identifying a composition of an aspirated material includes: controlling a surgical instrument to aspirate material through a probe that is fluidly connected with a vacuum source in an aspiration path. The method further includes estimating, during aspiration of the material, a flow rate of the material at the probe. The method further includes determining, using one or more sensors disposed along one or both of the aspiration path and infusion path, a change in pressure across the probe during aspiration. The method further includes determining a fluidic resistance of the material using the flow rate and the change in pressure, and providing feedback based, at least in part, on the fluidic resistance of the material and a reference value.

A method of identifying a composition of an aspirated material during a surgical procedure, the method comprising:

controlling a surgical instrument to aspirate material through a probe of the surgical instrument, wherein the probe is fluidly connected with a vacuum source in an aspiration path;
estimating, during aspiration of the material, a flow rate of the material at the probe;
determining, using one or more sensors disposed along one or both of the aspiration path and an infusion path, a change in pressure across the probe during aspiration;
determining a fluidic resistance of the material using the change in pressure;
and
providing feedback based, at least in part, on the fluidic resistance of the material and a reference value.
