摘要:
A steerable, tendon-driven endoscope is described herein. The endoscope has an elongated body with a manually or selectively steerable distal portion and an automatically controlled, segmented proximal portion. The steerable distal portion and the segment of the controllable portion are actuated by at least two tendons. As the endoscope is advanced, the user maneuvers the distal portion, and a motion controller actuates tendons in the segmented proximal portion so that the proximal portion assumes the selected curve of the selectively steerable distal portion. By this method the selected curves are propagated along the endoscope body so that the endoscope largely conforms to the pathway selected. When the endoscope is withdrawn proximally, the selected curves can propagate distally along the endoscope body. This allows the endoscope to negotiate tortuous curves along a desired path through or around and between organs within the body.

An endoscope with guiding apparatus is provided. The endoscope has an elongate body with a steerable distal portion, an automatically controlled portion, a flexible and passively manipulated proximal portion, and an externally controlled and manipulatable guiding apparatus. The guiding apparatus may be positioned within the endoscope or may be positioned adjacent to the endoscope. An interlocking device is provided to slidably interlock the guiding apparatus and the endoscope. When the guide is in a flexible state, it can conform to a curve or path defined by the steerable distal portion and the automatically controlled portion. The guide can then be selectively rigidized to assume that curve or path. Once rigidized, the endoscope can be advanced along the guide in a monorail or “piggy-back” fashion so that the flexible proximal portion follows the curve held by the guide until the endoscope reaches a next point of curvature within a body lumen.

A therapeutic treatment system has a delivery device is adapted to deliver a cooled breathing gas mixture to a patient and an injection device positioned near a distal end of the delivery device. The injection device is coupled to a source of liquid. The treatment system also includes a control system coupled to the delivery device and the injection device. Alternatively, the control system is adapted to control the injection device to release a fluid into the cooled breathing gas mixture to form a frozen mist of fine ice particles in the cooled breathing gas mixture.

The present invention relates, generally, to controlling a steerable instrument having an elongate body. More particularly, the present invention relates to a system and method for sensing the shape of a steerable instrument and controlling the steerable instrument in response to a control signal from a user input device and a shape signal corresponding to the sensed shape of at least a portion of the steerable instrument. The present invention also relates to a system for sensing the shape of a flexible instrument with an optical shape sensor.

One RFID equipped instrument includes an elongate body with a plurality of uniquely identified radio frequency identification chips spaced along the length of the elongate body. One system used for determining the position of an instrument includes an instrument; a plurality of radio frequency identification chips attached to the instrument; a reader connected to an antenna and adapted to communicate with each radio frequency identification chip using the antenna. One method for determining the position of an instrument using radio frequency identification chips includes providing a radio frequency identification chip reader and antenna; providing an instrument having a longitudinal axis and comprising a plurality of radio frequency identification chips placed along the longitudinal axis; moving the instrument relative to the antenna; and using information about a radio frequency identification chip detected by the antenna to determine the position of the instrument.

A connector assembly for controllable articles is described herein. The connector assembly engages force transmission elements used to transmit force from one or more force generators with the force transmission elements used to manipulate a controllable article. Additionally, the connector assembly provides organization thereby simplifying the process of connecting a plurality of elements, usually with a quick, single movement.
