Endoscopic Tissue Liquidization and Surgical Aspiration*

Abstract

A series of experiments has transformed a kitchen blender into an instrument worthy of evaluation in all forms of endoscopic surgery, namely the patented Endoscopic Tissue Liquidiser and Aspirator (ELSA). Robotic integration has been a successful academic exercise and could be the starting point for a new initiative (e.g., robot-guided biopsy of various organs). For soft, nonfibrous tissues, the ELSA is superior to the widely acclaimed Cavitron ultrasonic surgical aspirator in open surgery and is capable of being used endoscopically. Although prostatic tissue removal is difficult, it has been accomplished clinically in four cases. Urinary stones can also be destroyed.
