Building a framework for ergonomic research on laparoscopic instrument handles

Area of Science:

• Surgical Technology
• Ergonomics
• Human Factors Engineering

Background:

• Laparoscopic surgery offers minimal invasiveness but instrument design, particularly handles, has lagged.
• The ergonomic quality of laparoscopic instrument handles significantly impacts surgical outcomes and surgeon health.
• Existing research on handle ergonomics lacks standardization, hindering progress.

Purpose of the Study:

• To review the field of laparoscopic instrument handle ergonomics.
• To propose an evaluation framework for assessing handle ergonomics.
• To standardize future research and development in instrument handle design.

Main Methods:

• Comprehensive literature review of ergonomic studies on laparoscopic instrument handles.
• Analysis of existing evaluation frameworks, assessment systems (objective and subjective), and data analysis methods.
• Development of a proposed framework for ergonomic research.

Main Results:

• Identification of key ergonomic factors influencing surgical performance and surgeon health.
• Evaluation of current assessment methodologies in handle ergonomics.
• Proposal of a structured framework to guide future ergonomic research.

Conclusions:

• Standardized ergonomic research is essential for advancing laparoscopic instrument design.
• Implementing the proposed framework can lead to improved instrument handles.
• Better handle ergonomics will enhance surgical efficiency and protect surgeon well-being.
