摘要
Objective Based on the development background of digital medical technology,this study aimed to establish design guidelines and references in relevant fields to better serve clinical medical treatment using intelligent technology to enhance the usability of the interaction interface of robotic surgical systems and reduce potential human-factor risks during digital surgery.Methods Considering the robotic liver cancer ablation surgery system as the research object,subjective and objective evaluation indicators were established from 3 dimensions of effectiveness,efficiency,and satisfaction based on the usability theory.Using the hierarchical task analysis method,usability experiments were conducted to collect relevant data.Feedback on issues during the experimental process was obtained through observation and interviews.Failure mode and effect analysis and fault tree analysis were used to assess risk levels and formulate design strategies.Results The interface design of the liver cancer ablation surgery robot was iteratively optimized.The results showed that the interface after iteration improved in skilled operation time,subjective evaluation scores,risk priority number value,and risk level.The rationality of the scheme was verified,and interface design paradigm was constructed based on intelligent technology.Conclusion After improving the design,the interface effectively reduced the frequency of problems and average skilled operation time,thereby,improving the subjective satisfaction score of users.
