Abstract
An endoscope including: an elongated shaft comprising at least a first shaft tube with a window inserted in its distal end, and an electrical heating device arranged proximate to the window at or in the first shaft tube; wherein the heating device includes a flexible printed circuit board on which a resistive heating element configured as a conductor loop and a temperature sensor are arranged, and a heat-conducting structure connected in a thermally conductive manner to the temperature sensor is applied to the printed circuit board.
Claims22
An endoscope comprising:
- an elongated shaft comprising at least a first shaft tube with a window inserted in its distal end, and
- an electrical heating device arranged proximate to the window at or in the first shaft tube, wherein the heating device comprises a flexible printed circuit board on which a resistive heating element configured as a conductor loop and a temperature sensor are arranged, and
- a heat-conducting material at least thermally connected to the temperature sensor, the heat-conducting material being applied to the printed circuit board, the heat-conducting material comprising:
- a first portion adjacent to the temperature sensor and elongated in a first direction;
- and
- a second portion extending from the first portion in a second direction, the second portion being elongated in the second direction;
- wherein a first width of the first portion in a direction perpendicular to the first direction is greater than a second width of the second portion in a direction perpendicular to the second direction.
A heating device for use with an endoscope, the heating device comprising:
- a flexible printed circuit board on which a resistive heating element configured as a conductor loop and a temperature sensor are arranged, and
