Abstract
In an exemplary embodiment a head with an installed television camera is present which head is connected in a plug-in fashion to a mobile tube section. The control of the orientation of the head during video exploration is effected by a system of hydraulic fluid encased Bowden cables which can transmit not only mechanical forces but also electric energizing and signal currents and which permit a conducting away of dissipated heat. The transition from the tube section to the head is sealed off by means of drawover seal.
Claims11
An endoscope with electric image transmission, comprising:
- a head (1) with an installed camera, a mobile tube section (3) comprising a pivotal section (5) and a passively flexible section (4), a control device (8) and an image display device (11), the head (1) being connected in a plug-in fashion in said pivotal section (5) of the mobile tube section (3), and force transmitting cables (17) mechanically coupling said pivotal section (5) with said control device (8) for controlling the mobility of the pivotal section (5) of the tube section (3) and thereby effecting pivotal movement of said head (1), and said cables (17) being formed of electrical transmission means (25-28) capable of transmitting electrical energy as well as mechanical forces, and providing electrical coupling via said electrical transmission means (25-28) between said camera and said image dislay device (11), and said cables (17) comprising heat transmission means (27, 28) in heat transfer coupling with said head (1) via said pivotal section (5) for accommodating a carrying-off of dissipated heat from said head (1) to said cables (17), and a drawover seal (7) sealing the transition from the tube section (3) to the head (1).
