OBJECTIVE :

On completion of this module the student should be able to:
• Apply the established principles of ergonomics to theatre set up and instrument placement in practical
situations
• Demonstrate an understanding of the effect of the laparoscopic approach on the surgeon's movements
and performance
• Carry out a task analysis and assess endoscopic performance
• Assess the impact of new technology or instrumentation on surgical practice
• Appreciate what strategies need to be applied during the introduction of new technology

(MODULE 4 VISION)
