Methods and apparatus provide continuous guidance of endoscopy during a live procedure. A data-set based on 3D image data is pre-computed including reference information representative of a predefined route through a body organ to a final destination. A plurality of live real endoscopic (RE) images are displayed as an operator maneuvers an endoscope within the body organ. A registration and tracking algorithm registers the data-set to one or more of the RE images and continuously maintains the registration as the endoscope is locally maneuvered. Additional information related to the final destination is then presented enabling the endoscope operator to decide on a final maneuver for the procedure. The reference information may include 3D organ surfaces, 3D routes through an organ system, or 3D regions of interest (ROIs), as well as a virtual endoscopic (VE) image generated from the precomputed data-set. The preferred method includes the step of superimposing one or both of the 3D routes and ROIs on one or both of the RE and VE images. The 3D organ surfaces and routes may correspond to the surfaces and paths of a tracheobronchial airway tree extracted, for example, from 3D MDCT images of the chest.

The invention discloses a method and a system for introducing an electronic endoscope into operation with the assistance of a computer. The system comprises an electronic endoscope system, a space orientation system used for tracking a position and a direction of the probe head of the endoscope, an image workstation used for producing a planar or three-dimensional image of a surgery area of a patient according to an input image and blending and displaying an image of the probe head of the endoscope and the planar or three-dimensional image by connecting with the space orientation system, and auxiliary image orientation and processing software. The system tracks the position and the direction of the probe head of the endoscope through a space track technology and a computerized image processing technology, so that by combing the planar image with the image of the endoscope with the assistance of images as CT or X-ray pictures, a doctor can not only see the planar image captured by the probe head of the endoscope, but also see the position of the probe head of the endoscope and the conditions of the peripheral tissue. Therefore, the doctor can fully control the comparative position of the probe head of the endoscope in the body, thereby improving the quality of endoscope surgery and shortening the time of a surgery.

According to the present state of the art, endoscopic cannulation of the common bile duct and papillotomy and/or sphincterotomy of the Papilla of Vater and/or the Sphincter of Oddi is accomplished by advancing a sphincterotome (or papillotome or cannulotome) into an endoscope/duodenoscope so that the distal tip of the sphincterotome exits the endoscope adjacent the sphincter muscles at the Papilla of Vater. The endoscope mechanisms are then manipulated to orient the distal tip of the sphincterotome to the desired position for proper cannulation of the duct. Accurate and consistent control of the length of the exposed blade is made difficult due to a number of factors. These factors include: 1) differences in the inside diameters of the outer tube and the needle knife wire, 2) the orientation of the needle knife wire within the outer tube, 3) the mismatch of tolerance of the needle knife wire and the inside diameter of the extrusion, 4) anatomy, and 5) endoscope manipulation. A sphincterotome incorporating the present invention will provide the user with an indication of the exposed blade length and will allow the physician to control the length of the exposed blade. According to one embodiment of the present invention, various visual indications are presented to the user as the needle knife is advanced from its outer sheath. These visual indications, combined with a mechanical method to hold the knife in position during catheter placement allows the user to perform precise incisions. Presently available products that may be modified according to the present invention include, but are not limited to, Boston Scientific Sphincterotomes and Needle Knives.

A surgical instrument suitable for endoscopic operations having a gripping handle, tubular body and an operational tip.

Two or more jets converge at a convergence point laterally displaced at a predefined distance from the surface of the operational tip. The operational tip includes a heating member having an active face for contact heating a bleeding tissue. A rotating mechanism provides for independently rotating the jetting outlets and the active surface of the heating member relative to the gripping handle. A method for regulating the operating temperature of the heating member is provided.

An operation button for an endoscope is provided with a cylinder and a piston reciprocally slidable inside a lumen of the cylinder. A first flow channel and a second flow channel are formed to communicate with the lumen. When the piston is located at a first position, the first and second flow channel communicate with each other, while the first flow channel and the second flow channel are disconnected when the piston is located at a second position. A sealing member is provided on an outer periphery of the piston to provide secure airtightness between the cylinder and the piston. The sealing member includes a core member mainly made of one of poly-para-xylylene and poly-para-xylylene derivatives and a coating layer allocated on an outer periphery of the core member.

A medical device for viewing inside a body and for retrieving an object from a location within the body, the medical device comprising an endoscope having a tube defining a working channel and a basket engageable with the object. In one embodiment of the invention, the basket does not require a sheath and is disposed through the working channel such that the endoscope operates to contain or activate the sheathless basket. In another embodiment of the invention, a single push wire with a collar at its end is used in place of a sheath to control the opening and closing of the basket. In another embodiment of the invention, a tapered and funnel-shaped sheath surrounding the basket is used to contain or activate the basket. The invention minimizes the basket crossing profile so as to improve fluid flow in the working channel.

A measuring endoscope system includes a menu display module that selects a menu according to display data which is associated in advance with any of a plurality of optical adaptors, and a measuring program for performing measurement according to the result of the selection performed by the menu display module. Consequently, in the measuring endoscope system, when a user designates an optical adaptor using an optical adaptor selection screen image displayed on an LCD by the menu display module, a measuring technique associated with the optical adaptor is automatically selected. When a user wants to perform measurement using the measuring endoscope system, the user should merely press a measurement execution switch included in an endoscopic operation unit. Thus, measurement in which the selected measuring technique is implemented is carried out. Consequently, the present invention has succeeded in improving the maneuverability of a measuring endoscope system in measurement and improving the efficiency thereof in inspection.
