Robotic Assisted Tensioner- 2023
CORI Robotic Knee Tensioner
Advancing procedural innovation in robotic-assisted surgery, the CORI Digital Tensioner is a differentiated technology that helps solve challenges for surgeons
The CORI Digital Tensioner produces a surgeon-defined, quantifiable force to distract the knee joint, apply consistent tension to the ligaments, and provide objective gap data for procedure planning and execution.1,3 A small clinical case series showed the CORI Digital Tensioner reduced variability of tensioning by 64% when compared to a manual technique.
I worked as the Industrial Design Lead for the CORI Robotic Knee Tensioner as part of Smith + Nephew's Human Factors + Design Team. The goal with this device was to provide fast and accurate gap data for procedure planning, with a heavy focus on ergonomics. The form needed to be small, but easy to grip and maneuver while flexing the knee to collect gap data.
The first and only ligament tensioning device in robotic-assisted surgery to assess joint laxity in the native knee before performing bony resection. Automatic collection of gap data at a specified force through the full range of movement.
A true tensioning device using a software interface that allows surgeons to choose their preferred target force value (50±10N, 100±10N, or 150±10N)
