Medtech has identified a potential software issue for certain rosa brain and rosa one devices than can prevent it reaching a planned trajectory. when the robot arm is automatically sent onto a trajectory, cartesian coordinates are converted to joint configuration through a mathematical model, and for a very limited number of positions, the mathematical model is imperfect and may prevent the robot arm from reaching the desired position.For automatic moves, if the robot is sent to an unreachable trajectory, the device will display an error message and shut down. a delay of surgery can occur.For “isocentric micromoves” mode used during brain surgery, a hazardous situation can occur if an automatic micro movement to trajectory is planned and an instrument is inside the patient anatomy. if not detected by the user, this could lead to ineffective treatment, serious injury, or even death of the patient.To date medtech has not recorded any complaints for this issue.

Surgicom is currently working on a software correction for this issue, which is expected to be available in July 2017. Surgicom will contact users to arrange for installation of the software update. In the interim, users are to discontinue use of the micromovement function in isocentric mode during brain surgery. In addition, if the issue occurs for other automatic moves, when the error message "A difference in the expected and the actual robot position has been detected. The device will shut down" is displayed users are advised to follow the directions regarding restart and continuation of use of the device that are included in the customer letter.
