So it should come as no surprise that J&J’s DePuy Synthes business has kept relatively mum about the robotically assisted knee surgery device it’s been developing. J&J entered the competitive surgical orthopedic robot world when DePuy Synthes bought Paris-based Orthotaxy and its orthopedic-surgery robot prototype in 2018.
DePuy Synthes gave attendees at the recent American Academy of Orthopedic Surgeons conference a peek at the latest prototype of the Orthotaxy device. It’s is the size of a shoebox, attaches to an operating table and includes a saw, but does not do the sawing for the surgeon. Instead, the Orthotaxy platform will design the surgery plan and lock the saw into a plane, allowing the surgeon to do the cutting, according to Liam Rowley, VP of R&D for knees at DePuy.
“There are no blocks required. There’s no pinning required,” Rowley said. “We saw this as what the world actually needs. This is bed-mounted. It’s not a huge device that sits on the floor.”
