Robotic catheter system input device
First Claim
1. An input device for a robotic medical system including a medical instrument with a distal end, the input device comprising the following:
- a handle configured to be rotatable about an axis and to be longitudinally displaceable along the axis;
a first sensor configured to detect axial rotation of the handle;
a second sensor configured to detect longitudinal displacement of the handle along the axis;
a deflection control element disposed on or about the handle and configured to communicate with an electronic control system to selectively control deflection of said distal end of said medical instrument within a deflection plane; and
the electronic control system electrically coupled to the first sensor, the second sensor, and the deflection control element, the electronic control system configured to send control signals to the medical instrument,wherein longitudinal displacement of the handle results in the electronic control unit sending control signals to the medical instrument that result in a corresponding longitudinal motion of said medical instrument and rotation of the handle results in the electronic control unit sending control signals to the medical instrument that result in a corresponding rotation of the deflection plane.

Abstract
An input device for a robotic medical system includes a handle configured to be rotatable about a center axis, and to be longitudinally displaceable along the center axis. The input device also includes a deflection control element disposed on the handle and configured to selectively control deflection of the distal end of a flexible medical instrument electrically coupled to the input device. Longitudinal displacement of the handle may cause or result in a corresponding longitudinal motion or deflection of the flexible medical instrument. Rotation of the handle may cause or result in a corresponding rotation of the deflection plane. Longitudinal displacement and rotation of the handle may be detected or sensed electronically.

18. A device for controlling the robotic movement of a catheter, the device comprising the following:
-
a catheter handle control input device including a first sensor configured to detect motion in a first manner and a second sensor configured to detect motion in a second manner; and a control system configured to receive a control signal from the first and second sensors and is configured to relate displacement of the catheter handle control input device in the first manner to a first signal corresponding advancement or retraction of at least one of a catheter and a sheath, and displacement of the catheter handle control input device in the second manner to a second signal corresponding deflection of the distal end of at least one of a catheter and a sheath along a deflection plane, wherein the control system is configured to output the first signal and the second signal to the at least one of the catheter and the sheath. - View Dependent Claims (19, 20)
