The first electrical conductor includes a first bonding portion exposed from the pair of insulating layers and bonded to the treatment tool, the second electrical conductor includes a second bonding portion exposed from the pair of insulating layers and bonded to the heating pattern, the treatment tool includes a projection configured to project toward the flexible substrate and surround the heater, and the first bonding portion is bonded to the projection.
Abstract:
A heater unit includes a heater which is provided inside of a distal end portion of an endoscope insertion portion and which heats the inside to prevent fogging which occurs in an optical member provided the inside, a temperature sensor which measures the temperature of the inside and a flexible substrate. The heater unit further includes an insulating sealing portion which seals a mounting surface of the heater mounted on the flexible substrate, which seals the heater so that so that a joint surface of the heater that faces the mounting surface and that is joined to the lens frame is exposed and which seals the whole temperature sensor.
Abstract:
An antifogging device includes: an optical system having one or a plurality of optical members including at least an objective lens; a hollow casing in which the optical system is stored; a heater configured to generate heat according to supplied power to heat a hollow space in the casing; a temperature sensor configured to detect temperature of the hollow space; a temperature controller configured to estimate temperature difference between the temperature detected by the temperature sensor and temperature of the optical member, based on a power value of the supplied power; and an overall controller configured to control the heater based on the temperature difference estimated by the temperature controller.
Abstract:
An antifogging device includes: a heater configured to apply heat to an optical member; a temperature sensor configured to detect a temperature; a circuit board with a surface mounted the heater and the temperature sensor; a sealing member that is made of a resin material and that is applied to the surface to seal the heater and the temperature sensor; and a joining part that is provided on at least part of the surface and that is made of an inorganic material, the joining part being configured to: extend along a periphery of the surface in a state of being exposed to a side surface of the circuit board; and contact the sealing member.
Abstract:
In a state in which a heat generator and a temperature sensor are disposed on a wiring board, a measurement wiring is disposed in a vicinity of the heat generator, or the temperature sensor is disposed in a vicinity of a heat-generation wiring. A suppressing portion is disposed in either a first heat transfer path extending from the heat generator to the measurement wiring or a second heat transfer path extending from the heat-generation wiring to the temperature sensor. The suppressing portion suppresses heat transfer from the heat generator to the measurement wiring in the first heat transfer path, or suppresses heat transfer from the heat-generation wiring to the temperature sensor in the second heat transfer path.
Abstract:
An endoscope fogging prevention system includes a heater which heats inside of a distal end portion, a temperature sensor which measures heat quantity information regarding the inside and a control unit which controls the driving of the heater based on the heat quantity information measured by the temperature sensor. The fogging prevention system judging the operating characteristics of the heater and the operating characteristics of the temperature sensor based on the heat quantity information, and deactivating the heater when judging that the judgment result is out of a desired range.
Abstract:
A medical treatment apparatus is an apparatus for treating a living body tissue by heating the living body tissue. The apparatus includes a heat transfer portion, a heating chip and a flexible substrate. The heat transfer portion is configured to come into contact with the living body tissue and transfer heat to the living body tissue. The heating chip is disposed on the heat transfer portion and is configured to heat the heat transfer portion. The flexible substrate is partly joined to a first surface of the heat transfer portion on which the heating chip is disposed, with a remaining portion extending outside the heat transfer portion. A heating trace for supplying power to the heating chip is formed on the flexible substrate.
