摘要

Background Handheld laparoscopic robotized instruments have been developed to combine the advantages of a robotic operation system and conventional laparoscopic instruments. Direct objective standards are needed to quantify surgeons' skill level and validate the advantages of new instruments. This study describes and objectively evaluates the use of a robotized instrument using a force-sensing test platform. Methods The test platform consists of 12 rings on a hypersensitive force sensor. Forty volunteers were recruited: the expert group included 20 laparoscopic experts and the novice group included 20 medical students in their 4th year without laparoscopic skills. The baseline of the two groups was identified using a conventional needle holder. Participants then repeated the test with the robotized needle holder after training. The maximum force and impulse of each ring were analyzed for each group. Institutional review board approval is not needed for this study. Results Significantly lower maximum force and impulse were observed in the expert group than in the novice group during the baseline test (all P 0.05). Conclusions The maximum force and impulse recorded by a test platform can accurately identify participants' laparoscopic skill level. Six hours' training can ensure that experts master the use of the robotized needle holder, but this training session is too short for novices to improve their performance with a new instrument. The force-sensing test platform can reflect the suturing characteristics of users based on the skill level and is useful for laparoscopic suture training.
