Abstract:
An endoscopic treatment instrument includes a guide sheath. The guide sheath includes a second distal end, which has an inside diameter to insert the insertion portion therethrough so that the distal end of the insertion portion is configured to protrude relative to the second distal end. The guide sheath is inserted through the guide pipe so that the second distal end is configured to protrude relative to the first distal end of the guide pipe.

Abstract:
An image pickup apparatus includes a silicon layer, a wire layer that contains an insulator having a lower dielectric constant than silicon oxide, a cover glass that covers a light receiving portion on a light receiving surface of the silicon layer, and a silicon substrate that covers a back surface of the wire layer, in which a guard ring is formed along an outer edge on the wire layer, a through-hole having a bottom surface that is configured by an electrode pad configured by a conductor of the wire layer and having an outer periphery portion in contact with the silicon layer over a whole periphery is provided in a region of the silicon layer that is not covered with the cover glass, and the insulator of the wire layer is not exposed to an inner surface of the through-hole.
Abstract:
An arthroscopical surgical method using an ultrasonic treatment device for a joint includes: transmitting ultrasonic vibration to a treatment portion of the ultrasonic treatment device, removing an injured region of an articular cartilage so that a subchondral bone is exposed, and forming a cartilage edge which is nearly angled at 90° with the exposed surface of the subchondral bone to form a pool-shaped depression; forming a hole which pierces up to a cancellous bone of the subchondral bone through the depression, and scratching blood vessels in the cancellous bone; causing bleeding from the blood vessels so that blood is retained in the depression via the hole.
Abstract:
An image pickup apparatus includes: an image pickup device chip that has junction terminals, which is connected with an image pickup unit, on a reverse surface; a cable having lead wires connected with the image pickup unit; and a wiring board that includes junction electrodes joined to the junction terminals, terminal electrodes connected with the lead wires, wirings that connect the junction electrodes formed at a central portion and the terminal electrodes formed at extending portions, and a heat transmission pattern formed in a region where the junction electrodes, the terminal electrodes and the wirings are not formed, the extending portions being bent and thereby the wiring board being arranged within a projected plane of the image pickup device chip.
Abstract:
An image pickup unit for endoscope includes: an image pickup portion having a rectangular parallelepiped shape on which a plurality of semiconductor devices including a first semiconductor device and a second semiconductor device are stacked, the image pickup portion including an image pickup device, a device stack bonded to a rear surface of the image pickup device, and a reinforcing member formed by resin covering an outer peripheral surface of the device stack; and a signal cable connected to the image pickup portion, in which: the first semiconductor device on a rear end side is smaller than the second semiconductor device on an image pickup device side; and the reinforcing member has a thickness on the rear end side that is thicker than a thickness on the image pickup device side.
Abstract:
An image pickup apparatus includes: an image pickup chip including a light receiving section and electrode pads, on a first main face, and a plurality of connection electrodes, each of which is connected to each of the electrode pads via each of a plurality of through-hole interconnections, on a second main face; a transparent cover glass having a larger plan-view dimension than the image pickup chip; a transparent adhesive layer that bonds the first main face of the image pickup chip and the cover glass; and a sealing member that covers a side face of the image pickup chip and a side face of the adhesive layer, and is made of an insulating material having a same plan-view dimension as the cover glass.
Abstract:
An image pickup apparatus disposed in an endoscope includes an optical unit in which a plurality of optical members are stacked, an image pickup unit including an image pickup device and a plurality of semiconductor devices, mold resin covering the optical unit and the image pickup unit, and a wiring board bonded to the image pickup unit, in which a recess is provided on an outer peripheral surface of the mold resin.
Abstract:
An imaging apparatus includes: a lens unit in which a plurality of optical elements including one or more wafer-level lenses and a spacer are laminated; an imaging element configured to receive light incident from the lens unit, perform photoelectric conversion on the light, and generate an image signal; and a moisture-proof member that is bent and arranged so as to come in contact with at least a part of side surfaces of the lens unit to prevent moisture from entering a gap between the optical element and the spacer and/or a gap between the optical elements.
Abstract:
In an arthroendoscopical surgical method, a resection target area, which is emphasized by fluorescence with use of a fluorescent agent under excitation light, is identified on a meniscus, and a resection line or an imaginary resection line is drawn. Using an ultrasonic treatment tool and an arthroscope, the resection target area is resected by a probe which generates ultrasonic vibrations, based on the resection line or imaginary resection line under visible-light illumination, and an inclined resection surface is formed.
