This chapter provides a practical overview of essential surgical tools and imaging techniques used in emergency and trauma surgery, with particular emphasis on minimally invasive approaches. It outlines key principles for optimizing the safe use of surgical technology in acute settings, including patient and trocar positioning as prerequisites for effective tool deployment. The chapter reviews haemostatic and energy-based devices, mechanical stapling systems, and adjunct tools that support tissue dissection and reconstruction under time- and physiology-constrained conditions. In addition, perioperative and intraoperative imaging modalities—ranging from ultrasound and cross-sectional imaging to fluorescence-guided surgery and targeted endoscopic techniques—are discussed with respect to their role in diagnosis, operative planning, and intraoperative decision-making. Finally, the chapter addresses the limits and safe use of technology in emergency surgery, highlighting situations in which conversion to open surgery represents a prudent and patient-centered strategy. Overall, this chapter aims to support surgeons in the rational, context-driven integration of surgical tools and imaging technologies to enhance safety and outcomes in emergency settings.
