Optics-Based Surgical Debridement Assist Probe System

To address the Army’s need for a surgical debridement assisting device, Physical Optics Corporation (POC) proposes to develop new Optics-based Surgical Debridement Assist Probe (OSAP) system based on active optothermal radiometry for detecting debris in tissue and hyperspectral imaging technology that spectrally delineates dead tissue. The innovation in OSAP system design enables the system to detect small foreign bodies (1/2 mm) within the tissue with a detection rate >95% at tissue depths of about 6 cm. The unique system design allows low-power operation, avoiding extensive electrical power requirements; and eliminates surgeon/video interaction and extensive operational training requirements for the surgeon. The OSAP device will result in major cost savings for the government in terms of reduced clinical complications. In Phase I, POC will (1) demonstrate the feasibility on an in vitro tissue phantom; (2) develop an engineering design; (3) assemble a proof-of-concept prototype; and (4) in the Option, develop a plan and protocol for performing preclinical work. At the end of Phase II, the OSAP system will satisfy the general safety requirements of the International Organization for Standardization (ISO) Shelters and IEC 60601-1 Medical Electrical Equipment, and attain sufficient maturity to apply for FDA approval and clinical trials.
