Abstract: A medical intervention device may include a handheld device adapted for minimally invasive procedures. The device may include a handle that remains outside of the patient and an extension that extends from the handle into the patient and includes an end effector such as a forceps at a distal end. The mechanical operating relationship between the extension and the end effector may provide for motion about multiple intersecting axes thereby avoiding a need for compensating motion. In particular, yaw and pitch motion may be imparted independent of one another and avoiding a need for compensating motion of one axis for another. Moreover, the mechanical operating relationships of the device be configured for precisely mimicking the hand motion of the surgeon or other user and may include ratioed motion that provides for more precise motion at the end effector than at the handle and/or tremor control.
