METHOD AND SYSTEM FOR SURFACE SAMPLING

摘要

A system and sampling probe adaptable to an ultrasonic surgical instrument applies irrigation fluid and ultrasonic or vibrational energy to a target, and aspirates material desorbed from the target into a pick-up conduit. A suction source at the distal end of the conduit may aspirate the material released from the target with the irrigation fluid, thus efficiently sampling a broad range of materials from an arbitrary target to produce an analyzable effluent analyte stream which may be ionized and provided to the inlet of an ion-type analysis instrument, or may be fed directly to an instrument such as a flow cytometer, IR or fluorescence spectrophotometer, or other analyzer. Carrier gas may be provided to more effectively transport the desorbed material, and the probe may be incorporated into a robotic device to automatically carry out surface imaging or to effect sampling in hazardous environments.
