Description

This invention relates to an endoscopic device. Some endoscope systems are separated into a processor unit and a scope unit. The scope unit contains the endoscope, and at the tip of the endoscope is an imaging module equipped with numerous components such as an image sensor and lens. The flexible tube section of the scope unit houses wiring for video signals, power cables, control cables, etc. A medium-sized electrical connector is used to connect the processor unit and the scope unit. A configuration for contactless power supply at the connection point is known, where the scope unit's connector is equipped with a power receiving coil, and the processor unit's connector is equipped with a power transmitting coil. Due to factors such as higher resolution image sensors, the power consumption of the scope unit may increase in the future. Patent Document 1 describes an endoscope device that performs such contactless power supply.

Hereinafter, embodiments of the present invention will be described based on the attached drawings. [Embodiment 1] Figure 1 is a block diagram of an endoscope device according to Embodiment 1 of the present invention. The endoscope device 10 may be what is called an electronic endoscope, or it may be a device specifically designed for medical use. The endoscope device 10 comprises a processor unit 20 and a scope unit 30. The processor unit 20 comprises a power transmission coil 21 and a control board 22. The control board 22 functions as a control device that controls the processor unit 20 or the entire endoscope device 10, and can be configured, for example, using a computer equipped with arithmetic and storage means. The scope unit 30 comprises a power receiving coil 31 and an endoscope 32. The endoscope 32 may have a known configuration, but for example, it may include, in order from the tip, a rigid, non-deformable portion, a flexible portion that can be actively bent in response to operation, and a passively deformable, flexible portion. An image sensor (described later with reference to Figure 2, etc.) is attached to the rigid portion. The processor unit 20 or the scope unit 30 may include an operating unit for controlling the endoscope 32. The user of the endoscope device 10 can control the operation of the endoscope 32 by operating the operating unit. For example, the bendable portion of the endoscope 32 bends in response to operation on the operating unit. The bendable portion can be realized using a well-known mechanism incorporated into general electronic endoscopes; for example, it may be configured to bend by pulling an operating wire linked to the rotation of a knob included in the operating unit. The endoscope 32 can be inserted into any body cavity within the body, including its tip, and can be inserted into areas such as the bronchi, bile ducts, pancreas, hepatic ducts, and urinary tract. The processor unit 20 and the scope unit 30 are configured to be detachable from each other, i.e., to be separably coupled. When the processor unit 20 and the scope unit 30 are coupled to each other, contactless power supply from the transmitting coil to the receiving coil is possible. Figure 2 shows a more detailed configuration of the processor unit 20 and the scope unit 30. In the processor unit 20, the second controller 212 controls the power transmission coil 21, thereby controlling the power supplied to the scope unit 30. The power source for the supplied power may be a battery built into the processor unit 20 or an external power source. Furthermore, the second controller 212 processes signals transmitted and received between it and the scope unit 30. The subsequent signal processing circuit 270 processes the input and output signals of the second controller 212. The first controller 211 controls the second controller 212 and the subsequent signal processing circuit 270. In particular, the second controller 212 controls the laser driver 260, and the laser driver 260 controls the laser diode 250. The laser diode 250 transmits control optical signals to the scope unit 30, thereby controlli
