Abstract
A surgical stapler system for real-time tissue perfusion assessment during clamping includes a powered surgical stapler with a handle assembly, adapter assembly, and an end effector comprising a reload assembly with staples and an anvil assembly. Integrated into the system is a near-infrared spectroscopy (NIRS) system featuring light sources and photodetectors. The method involves clamping tissue between the reload and anvil assemblies, transmitting near-infrared light through the clamped tissue, and detecting backscattered light to determine tissue perfusion levels. The perfusion data is processed and displayed in real-time, allowing adjustments to the clamping force to ensure adequate perfusion before stapling. The system enhances surgical outcomes by providing real-time feedback on tissue viability during critical phases of the stapling procedure.
