Provided are an endoscopic surgical device and an overtube that allow the state of a distal end of a treatment tool to be easily checked while achieving a decrease in the diameter of the overtube, and can improve surgical efficiency, in a configuration in which an endoscope is made to be movable forward and backward in an interlocking manner with the forward and backward movement of a treatment tool. An overtube 300 to be inserted into a body wall is provided with an endoscope insertion passage 306 through which the endoscope is inserted and a treatment tool insertion passage 308 through the treatment tool is inserted, the treatment tool insertion passage 308 is provided parallel to a reference axis 300a of the overtube 300, and the endoscope insertion passage 306 is provided obliquely to the reference axis 300a. A slider, which is engaged with the endoscope and the treatment tool inserted through the respective insertion passages and causes the endoscope and the treatment tool to interlock with each other and move forward and backward, is arranged inside the overtube 300 so as to be movable in a forward-backward direction of the overtube 300. An endoscope engagement part engaged with the endoscope in the slider is movable in an upward-downward direction, and moves upward and downward along the position of the oblique endoscope insertion passage 306 together with the movement of the slider in the forward-backward direction.

The present invention discloses a flexible-wire traction-type capsule endoscope and a manufacture method thereof, which mainly includes a capsule endoscope housed in a pockety body and leads out a flexible wire for traction. The manufacture method of the flexible-wire traction-type capsule endoscope includes steps of mold integrating, film coating, adhering, shaping, assembling, sealing and wire fixing. According to the present invention, a finished product of the flexible-wire traction-type capsule endoscope is prepared by assembling a conventional capsule endoscope with a processed pockety body, and finally sealing and fixing. The manufacturing technique of the product is simple and easy, raw materials used are natural without pollution and are cheap, and the processing procedure is easy to be automatized, i.e., the productivity is easy to improve; from the aspect of application, the flexible-wire traction-type capsule endoscope has a small structure volume, is easy to swallow, and causes small negative reactions to patients.

A gastrointestinal tract diagnosis device, comprising: an endoscope (10) having a substrate (122) and a control unit (1220) and a recognition marker (1220') therein; an image capturing module (13)including a first lens (131) and an image sensor (131a) that are disposed on the substrate (122); an illuminating module (14) including a first light source (141) disposed on the substrate (122); an enclosure body (15) assembled to a connection device (17) to waterproofingly enclose the image capturing module (13)and the illuminating module (14); and a work station (30) connecting to the endoscope (10) to access the recognition marker (1220') to add a machine identity into the recognition marker (1220') to match with the endoscope (10), wherein the work station (30) determines if a usage state of the endoscope (10) is overdue; the work station (30) determines if the endoscope (10) has connected to an another work station (30) different from the work station (30) by the recognition marker (1220') and the machine identity. A control method based on the above device is also provided.
摘要:
A structure of an imaging part in a catheter is provided that is capable of easily enlarging the angle of view, and moreover hinders the ingress of surrounding debris and fluids such as bodily fluids into the space between the object lens system and the light receiving surface of the solid state imaging element. For that reason, the structure of an imaging part has an object lens system in which light from an observation object region is incident; and a solid state imaging element for receiving an outgoing light from the object lens system and photoelectrically converting an image of the observation object region, in which at least a lens face of a light outgoing side of the object lens system is formed to be planar, and the lens face of the light outgoing side of the object lens system is joined to the light receiving surface of the solid state imaging element.

An image pickup system comprises an image pickup portion that outputs an electric signal obtained from a plurality of pixels by photoelectric conversion as image information; a transmission portion that transmits the image information outputted by the image pickup portion to outside; a reception portion that receives a synchronization signal that is transmitted periodically from outside; calculation means that carries out processing to perform a predetermined calculation on a period of the synchronization signal that the reception portion receives; and a transmission control portion that controls the transmission portion based on a second synchronization signal that takes a value that is based on a calculation result of the calculation means as a period.

An image pickup section 10 includes a sensor section 15 which picks up an image of an object, a control register section 12 which controls the sensor section 15, a nonvolatile memory 13 which stores setup data to be set in the control register section 12, a control signal interface section 11 which sets the setup data stored in the nonvolatile memory 13 in the control register section 12, and an initialization check register 24 which detects an abnormality of the control register section 12. When an abnormality is sensed by the initialization check register 24, the control signal interface section 11 reads out setup data from the nonvolatile memory 13 and performs control so as to reset the setup data in the control register section 12.
