Abstract: Provided is an endoluminal device system including: an elongated and flexible endoluminal device; a wire that is disposed in the endoluminal device; a first sensor that detects tension of the wire; a second sensor that detects displacement of the wire; a driving device capable of pulling the wire; and a processor. The processor is configured to: cause the driving device to execute a relaxing operation for relaxing the wire, acquire the tension and the displacement of the wire during the relaxing operation, which are detected by the first sensor and the second sensor, respectively, and adjust a control parameter of the endoluminal device based on a rate of change in the tension with respect to the displacement.

Abstract: A medical manipulator system includes: a medical manipulator having a movable portion; and a drive device to which the medical manipulator is detachably connected. The medical manipulator includes a driven portion to which a driving force for driving the movable portion is input. The drive device includes: a drive portion that is attached to the driven portion when the medical manipulator is connected and drives the driven portion; and a controller that controls the drive portion. The number of the drive portions is greater than the number of the driven portions. The drive device is capable of simultaneously connecting a first manipulator and a second manipulator that are the medical manipulators. All of the driven portions of the first manipulator and the second manipulator are attachable to the drive device.

Abstract: Treatment device for ultrasonic treatment and high frequency treatment procedure is equipped with an ultrasonic transducer including piezoelectric elements converting electrical power into ultrasonic vibrations. The treatment device includes a transmission rod with a treatment probe and jaw for clasping objects. The transmission rod includes one or more features for damping, to minimize or prevent excess vibrations and to, among other things, decrease frictional heat caused by the friction between the damping features and the transmission rod arising from attenuating the ultrasonic vibrations.
