Ergonomic deficiencies in the operating room: examples from minimally invasive surgery

Area of Science:

• Surgical Technology
• Human Factors Engineering
• Orthopedics

Background:

• Minimally invasive surgery (MIS), particularly laparoscopic gallbladder removal, is increasingly prevalent.
• Laparoscopy limits surgeon's direct visualization and tactile feedback compared to open surgery.
• Current laparoscopic setups often lead to suboptimal ergonomics for surgical teams.

Purpose of the Study:

• To identify ergonomic challenges faced by surgeons during laparoscopic procedures.
• To define ideal surgeon posture and ergonomic requirements for laparoscopic surgery.
• To discuss necessary adjustments in operating tables, monitor placement, and interfaces.

Main Methods:

• Review of existing literature on MIS ergonomics.
• Analysis of surgeon's visual and physical constraints during laparoscopy.
• Description of an ideal ergonomic setup for laparoscopic surgeons.

Main Results:

• Laparoscopic surgery restricts the surgeon's view and reduces hand-eye coordination.
• Instrument design and operating table height contribute to unnatural postures.
• Limited monitor positioning and lack of tactile feedback negatively impact surgeons.

Conclusions:

• Ergonomic factors in MIS significantly influence surgeon comfort and potentially patient outcomes.
• Optimizing operating table height, monitor placement, and instrument design is essential.
• Addressing these ergonomic issues can lead to improved surgical performance and reduced surgeon strain.
