  • Patent number: 7575548
    Abstract: In an endoscopic treatment instrument having a plurality of sheaths, a supporting member for directly and indirectly supporting the plurality of sheaths, and a connecting member for directly/indirectly bringing the sheaths and an endoscope in a connected state are provided. The supporting member constrains a relative position of the plurality of sheaths and the connecting member can change the connecting state. Therefore, when an operator changes the connecting state of the connecting member, the positional relation of the endoscope and the plurality of sheaths can be changed, while the positional relation of the plurality of sheaths is still constrained. Accordingly, for example, left and right sheaths can be easily exchanged.

  • Patent number: 7516283
    Abstract: Data is stored in a non-volatile memory such as a flash memory. The non-volatile memory has two memory areas. When power of a device is turned on, data in the two memory areas are compared to determine which memory area includes old data, and the old data is erased. When the power is turned off, a control setting of the device used immediately before the power is turned off is stored as new data in the memory area from which the old data is erased. When the power is applied again, the new data is read, and the control setting is restored in the device.
