New sensorized laparoscopic instruments can distinguish between novice and expert surgeons during suturing tasks. These tools offer potential for improved minimally invasive surgical training and performance assessment.

Area of Science:

Surgical Technology
Medical Simulation
Robotics in Medicine

Background:

Minimally invasive surgery (MIS) training faces challenges due to environmental constraints.
Developing objective metrics for surgical skill assessment is crucial for effective training.

Purpose of the Study:

To evaluate novel sensorized laparoscopic instruments for their ability to differentiate surgical skill levels.
To assess the construct validity of force and position data from these instruments in a surgical task.

Main Methods:

Sensorized laparoscopic instruments with 5 degrees of freedom (DOF) force sensing and 6 DOF position sensing were utilized.
Novice and expert laparoscopists performed a standardized suturing task using the novel instruments.
Force and position data profiles were collected and compared between skill groups.
