Abstract: A method for detecting a capsule camera entering into or exiting the GI tract, includes (a) taking a first test image under the condition that an illumination system of the capsule camera is disabled; (b) taking a second test image under the same condition as the first test image; (c) comparing selected corresponding pixel values of the first test image and the second test image to determine if a significant change in pixel values has occurred; and (d) upon detecting the significant change in pixel values, determining if the capsule camera has entered or exited the GI tract, and performing operations appropriate to follow such determination. The appropriate operations performed after detecting the capsule camera's exit from the GI tract includes stopping further taking or storing of images and, optionally, activating an audio signal to indicate the capsule camera has exited the GI tract.

Abstract: A pulp chamber locator assists a dentist in performing a root canal procedure. The device includes a generally circular plate and a plurality of struts extending from the plate. The plate has a hole in the vicinity of its center. The device is inserted over a tooth, such that the struts engage the cemento-enamel junction of the tooth. The hole then indicates the proper point of entry for a dental instrument. The device may also include a rotatable indicator for showing the proper angle of entry, to insure that the instrument reaches the pulp chamber of the tooth. The dentist adjusts the position of the indicator, based on information provided by an X-ray or equivalent, and positions the dental instrument so as to be generally parallel with the indicator.

Abstract: An object of the present invention is to actively control at least one of the position and direction of the imaging field in a subject and to observe a desired observed region in the subject certainly in a short period of time. A body-insertable device system according to the present invention includes a capsule endoscope 1 introduced into a subject and a permanent magnet 3. An imaging unit of the capsule endoscope 1 for taking an image inside the subject is fixed in a casing. The capsule endoscope 1 includes a drive unit for changing at least one of the position and posture of the casing in the liquid 2a which is also introduced in the subject 100. The permanent magnet 3 controls the operation of the drive unit for changing at least one of the position and posture of the casing in the liquid 2a.

Abstract: The present invention provides method and system for data communication in the human body and a sensor therefor. The method and system transmit information through the human body to a receiver located outside the human body using low current and voltage polarity, so that they cause no damage to the human body and achieve low power consumption and better receiving sensitivity. In addition, the sensor contains a CMOS image sensor on which all circuits are integrated without radio transmitter and antenna, so that it achieves a low-priced and small-sized capsule type endoscope.

Abstract: A body-insertable apparatus including a capsule-like casing, an illuminating unit, an imaging unit, and an antenna is provided. The capsule-like casing is formed in a capsule-like shape and includes a transparent imaging dome. The illuminating unit is arranged in the capsule-like casing and illuminates an examined site of a subject through the imaging dome. The imaging unit is arranged in the capsule-like casing and takes an image of the examined site illuminated by the illuminating unit. The antenna is arranged in the imaging dome at a position outside an imaging field of view of the imaging dome to transmit image information obtained through imaging by the imaging unit to an outside of the subject.

Abstract: The invention includes an insertion portion, one end of which is inserted inside a lumen of a subject; an image-acquisition unit for acquiring an image of an interior wall in the lumen as a substantially circular or substantially ring-shaped interior wall image; a transformation processing unit for transforming, in the interior wall image, at least substantially ring-shaped images concerning the interior wall, whose distance from the one end is uniform, to substantially straight-line-shaped or substantially band-shaped images; a distance-measuring unit for measuring a distance moved by the insertion portion relative to the subject; and an image synthesizing unit for joining the transformed images on the basis of the distance moved measured by the distance-measuring unit.

Abstract: A capsule endoscope includes a string that has one end attached to a main body of the capsule endoscope and another end secured at a predetermined position, and a wind-up unit that is provided in the main body of the capsule endoscope to bring out and wind up the string.

Abstract: A reciprocating surgical file system for precisely removing bone and/or other tissue is described. The system allows a user to maneuver the system and navigate into hard-to-access sites under a direct vision mechanism. A transmission mechanism converts rotary motion from a motor into reciprocating motion and provides it to the surgical file for precision removal of bone or other tissue. A pulsatile pump mechanism is operatively coupled with the transmission mechanism and provides irrigating fluid to the surgical site.

Abstract: A method for the reconstruction of missing, broken and/or abraded teeth by means of face analysis. In order to determine the shapes and sizes of the teeth, the face of a patient, for whom the teeth are intended, is measured by means of one or more image-type pictures. The respective tooth size and tooth shape is determined proportionally from the obtained values.

Abstract: An endoscope device includes an optical coupler, an image pickup module, a second bundle of optical fibers, a photodetector and an image processing module. The optical coupler has an input end optically coupled to a light source, a first output end and a second output end. The image pickup module includes a lens module and a first bundle of optical fibers. A end of the first bundle of the optical fibers is optically coupled to the output end of the optical coupler. An opposite end of the first bundle of the optical fibers is configured for emitting the light to illuminate an object. The second bundle of optical fibers has a end optically coupled to an image side of the lens module. An opposite end of the second bundle of the optical fibers and the second output end of the optical coupler are optically coupled to the photodetector.

Abstract: An integrated modular dental measuring apparatus and method of use for producing edentulous dentures, each including a lower dental tray having a removable modular contact plate with an upwardly extending shoulder surrounding a tapered opening, a ball nut retained in the tapered opening, and a post adjustably secured to the ball nut. A modular striking plate may be removably attached to an upper dental tray or an integrated striking sector on a bottom surface of the upper dental tray is utilized to accurately obtain an established occlusal vertical and centric relation positions. The contact plate and striking plate are each configured as snap-in components to the respective trays. Additionally, the contact plate may be utilized as a spacer between the dental trays once the post and ball nut are removed. Finally, the contact plate and striking plate may be removed for functional positioning and esthetic blue printing measurements.

Abstract: An electric bending endoscope device includes an endoscope with a driving unit, a control unit and an operation portion with a bending instruction portion. The operation portion includes a correction algorithm calculating portion in which the output range of instruction signal of the joystick is converted to coincide with the predetermined output range of the bending instruction portion instruction-signal being the operation signal outputted by the operation portion according to the joystick being the bending instruction portion to be fitted to the operation portion, to generate the bending instruction portion operation-signal.

Abstract: A control system for allowing a user to control the orientation of a medical device or a medical instrument in a variety of directions. An actuator selectively tensions one or more control cables having ends secured at or adjacent a distal tip of the medical device in order to bend the distal tip in a desired direction. In one embodiment, a physician can adjust the movement of the distal tip in a desired direction without affecting the orientation of the medical device in other directions.
