Validation of a training system for laparoscopic longitudinal suturing in lesion
Background
A training system that allows the trainee to perform laparoscopic suturing in a realistic environment and measures the force applied to the tissue would be invaluable. This study aims to establish the construct and content validity of the training system we developed for the objective assessment of surgeons' skills.
Methods
Ten novices, 6 residents, and 6 experts performed the suturing and knot-tying task using the training system. Ten force-related parameters were used to analyse the system's construct validity. Experts were invited to evaluate the content validity with questionnaires.
Results
Eight parameters showed significant differences between the three groups. The construct validity results demonstrated that the system could distinguish the tissue handling ability of operators. The experts agreed that the system had excellent content validity with an average score of 4.71/5.
Conclusions
The training system is likely valid for surgical training. It can realistically simulate surgical scenarios and evaluate the tissue handling ability of trainees.
期刊介绍：
The International Journal of Medical Robotics and Computer Assisted Surgery provides a cross-disciplinary platform for presenting the latest developments in robotics and computer assisted technologies for medical applications. The journal publishes cutting-edge papers and expert reviews, complemented by commentaries, correspondence and conference highlights that stimulate discussion and exchange of ideas. Areas of interest include robotic surgery aids and systems, operative planning tools, medical imaging and visualisation, simulation and navigation, virtual reality, intuitive command and control systems, haptics and sensor technologies. In addition to research and surgical planning studies, the journal welcomes papers detailing clinical trials and applications of computer-assisted workflows and robotic systems in neurosurgery, urology, paediatric, orthopaedic, craniofacial, cardiovascular, thoraco-abdominal, musculoskeletal and visceral surgery. Articles providing critical analysis of clinical trials, assessment of the benefits and risks of the application of these technologies, commenting on ease of use, or addressing surgical education and training issues are also encouraged. The journal aims to foster a community that encompasses medical practitioners, researchers, and engineers and computer scientists developing robotic systems and computational tools in academic and commercial environments, with the intention of promoting and developing these exciting areas of medical technology.
