Light source apparatus

A light source device includes a light-condensing device that condenses an illumination light that is emitted from a light source lamp. The light-condensing device includes at least one lens, a lens holder in which a lens is fixedly provided, and a lens holding member. The lens holding member is a member for fixing a lens to the lens holder. The lens holding member causes at least one circumferential portion of the lens to protrude to the lens holder side, and causes the optical axis of the lens to match the optical axis of the illumination light.

Light source device

A light source device includes a light source lamp, a rotary plate, a heat absorbing portion, and a filter mounting member. The light source lamp emits illumination light. The rotary plate includes multiple opening portions that are selectively disposed in the illumination light path of the light source lamp. A reflective filter that reflects light of a wavelength that acts a heat source in illumination light is provided in one of the multiple opening portions of the rotary plate. The heat absorbing portion absorbs heat included in reflected light reflected by the reflective filter in the opening portion. The filter mounting member disposes the reflective filter in the opening portion at a predetermined angle of inclination to the optical axis of the illumination light. By disposing the inclined reflective filter in the illumination light path, reflected light reflected by the reflective filter is reflected towards the heat absorbing portion.

An endoscope shape detection system has a CPU included in a control unit. The CPU performs frequency sampling of digital data to calculate coordinates indicating the spatial positions of source coils incorporated in an insertion unit of an endoscope received in a patient and of marker coils placed on a patient. An inserted state of the insertion unit of the endoscope is estimated based on the calculated coordinate data indicating the positions of the source coils. Display data based on the shape of the endoscope is produced from the calculated coordinate data indicating the positions of the source coils, and output to a video RAM. Display data of the marker coils is produced from the calculated coordinate data indicating the positions of the marker coils, and output to the video RAM. Consequently, the positions of the markers are depicted together with the shape of the endoscope. The positional relationship between the insertion unit of the endoscope and a patient's body can therefore be ascertained.

System for detecting the shape of an endoscope using source coils and sense coils

An endoscope shape detecting system displays an endoscope image and an insertion form image simultaneously on a display means. A first memory stores an endoscope image and a second memory stores an insertion form image. A control device controls a switching action such that the insertion form image is output to the display means during a period wherein the output of the endoscope image to the display means is turned off and stored in the first memory means, and that the output of the insertion form image to the display means is turned off and stored in the second memory during the period wherein the output of the endoscope image to the display is turned on. In addition, a control device is provided that controls the storing action such that a first period for storing endoscope images in the first memory and a second period for storing output signals from a magnetic field detecting device in the second memory do not overlap.

Endoscope shape detecting apparatus wherein form detecting processing is controlled according to connection state of magnetic field generating means

An endoscope shape detection system has a CPU included in a control unit. The CPU performs frequency sampling on digital data to calculate coordinates indicating the spatial positions of source coils incorporated in an insertion unit of an endoscope and of marker coils. An inserted state of the insertion unit of the endoscope is estimated based on the calculated coordinate data indicating the positions of the source coils. Display data based on which shape of the endoscope depicted is produced from the calculated coordinate data indicating the positions of the source coils, and output to a video RAM. Display data based on which marker coils are depicted is produced from the calculated coordinate data indicating the positions of the marker coils, and output to the video RAM. Consequently, the positions of the markers are depicted together with the shape of the endoscope. The positional relationship between the insertion unit of the endoscope and a patient's body can therefore be ascertained.

A source coil line-break/short-circuit detecting circuit and a probe connection detecting circuit are provided to the source coil driving circuit unit of an endoscope shape detecting apparatus. The source coil line-break/short-circuit detecting circuit detects line-breaks and short-circuits of the source coils. The probe connection detecting circuit detects whether a connection exists with a probe. A marker coil line-break/short-circuit detecting circuit detects line-breaks and short-circuits of the marker coils. A marker connection detecting circuit detects whether a connection exists with a marker. Accordingly, using the apparatus without being connected to a probe or markers can be avoided by detecting the connection of the probe and markers by the probe connection detecting circuit and marker connection detecting circuit, respectively, when the system is energized, thereby avoiding detecting noise and consequently displaying a random image on the monitor.
