The da Vinci Surgical System is a medical robotic technology used for minimally invasive surgery. When used according to instructions, the cannulae are unlikely to become damaged. The total reported cannulae damage occurrence rate is approximately 0.52%. In addition to the recall, Intuitive Surgical is revising its Single-Site labeling to instruct users how to inspect cannulae prior to use and to appropriately handle cannulae during use.
Affected lots were manufactured between December 2010 and August 2012. All affected cannulae will be replaced with a new version that can withstand higher force and is less likely to become damaged by incorrect placement. For more information see intuitivesurgical.com.
