Rosa Brain (robot surgeon)

2019: Defects

In the middle of September, 2019 Zimmer Biomet recognized existence of defects in Rosa Brain 3.0 robots neurosurgeons. Because of failure in the software they do inexact skull operations: according to warning of the company, the incorrect sequence of transactions can cause "discrepancy between initial marking of skin on a skull and a tool trajectory".

According to the producer, this problem did not lead to development of the long-term undesirable phenomena. In all cases the problem was revealed by the surgeon controlling transaction visually and/or using program hints of software therefore for patients these defects did not turn back serious effects yet. The problem concerns only models of the Rosa Brain 3.0 robot neurosurgeon and does not mention other robots with support of Rosa which are applied at brain and backbone operations. Zimmer received the line of Rosa robots when in 2016 it purchased the French company Medtech in Montpellier.

To fix a problem, the company works on updating of program providing the robot to the version of Rosa Brain 3.1. Meanwhile, Zimmer actively cooperates with surgeons who are forced to work with the rejected devices, sending them warnings and recommendations. The company also independently announced regulatory bodies need of updating of the module Rosa Brain 3.0. It is expected that regulatory bodies will estimate the revealed defects soon and will begin a withdrawal of the failing software.

The Rosa Brain, Rosa Spine and Rosa One models not for the first time draw so close attention because of problems with the software. In 2017 the company informed surgeons on an internal problem because of which the manipulator of the robot can not reach desirable provision during the automatic work because of an imperfect mathematical model. This problem was also fixed at the following software updating.^[1]
