The study will examine the safety and performance of a new surgical smoke clearance system designed for use during laparoscopic surgery.

The study will examine the safety and performance of a new surgical smoke clearance system which has been developed to maintain a visually clear operative field during laparoscopic surgery by using electrostatic precipitation to clear, from the surgical field, smoke and plume produced by energy based surgical instruments e.g. electrocautery, laser tissue ablation and ultrasonic scalpel tissue dissection.
