摘要: Objective To assess critical heat spread of cautery instruments used in robot-assisted laparoscopic (RAL) surgery. Materials and methods Thermal spread along bovine musculofascial tissues was examined by infrared camera, histology and enzyme assay. Currently used monopolar, bipolar and ultrasonic laparoscopic instruments were investigated at various power settings and application times. The efficacy of using an additional Maryland clamp as a heat sink was evaluated. A temperature of 45 C was …
