The da Vinci 5 (dV5) system is the first da Vinci platform to incorporate true force feedback (FFB), enabling real\u2010time transmission of instrument\u2010tip forces to the surgeon. However, the quantitative impact of FFB sensitivity settings remains unclear. This study represents the first Japanese clinical evaluation of dV5 FFB in colorectal surgery.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n We conducted a case\u2010series analysis of 10 consecutive robotic colorectal cancer resections performed using the daV5 system by a single Japan Society for Endoscopic Surgery\u2013certified surgeon. Instrument\u2010tip force data (Newtons) from the first arm were extracted from system logs. Average forces were analyzed according to FFB sensitivity settings. Analyses were descriptive given the small sample size.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n Under the medium sensitivity setting, the overall mean instrument\u2010tip force was 1.68\u2009N. Mean forces increased stepwise as sensitivity decreased: high 1.40\u2009N, medium 1.68\u2009N, low 2.60\u2009N, and off 2.70\u2009N, demonstrating a clear dose\u2010dependent relationship (off\/low\u2009>\u2009medium\u2009>\u2009high). Left\u2010sided and rectal procedures tended to require slightly higher forces than right\u2010sided colectomy. Transient force peaks were mainly attributable to instrument interference. No tissue injury was identified on video review.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n FFB in the dV5 system may enable quantitative, sensitivity\u2010dependent modulation of instrument\u2010tip force during colorectal surgery. FFB reduced applied forces in a dose\u2010dependent manner, supporting its role as a force\u2010control mechanism rather than merely a sensory adjunct. However, its impact on tissue handling and clinical outcomes remains unclear, given the absence of grasping force evaluation.<\/jats:p>\n
