  • Publication number: 20090234223
    Abstract: According to the invention, an endoscope system as a surgery assisting apparatus includes a surgery apparatus for performing treatment by abdominal operation procedure on a region to be treated in a body of a patient, and a luminal organ shape detecting apparatus used for assisting (supporting) the abdominal operation procedure. The luminal organ shape detecting apparatus is used as blood vessel position notifying means when procedure is performed by inserting a probe as a luminal organ insertion probe into a blood vessel, for example. This allows the luminal organ irrespective of the treatment to be easily and surely detected and enables a smooth procedure to be performed.

  • Publication number: 20090030306
    Abstract: A detecting apparatus includes: a change-over switch for switching on/off display of a scope model on a liquid crystal monitor; a position calculating portion for calculating respective positions of source coils; a scope model generating portion for generating a scope model of an electronic endoscope based on the respective positions of the source coils calculated by the position calculating portion; and a selector for selectively outputting to the liquid crystal monitor a display-pause-time image stored in a display-pause-time image storing portion and a scope model image from the scope model generating portion; and a control portion for controlling each of these portions. The detecting apparatus thus displays an insertion shape of the endoscope at a timing as needed.

  • Patent number: 7388184
    Abstract: The image reading device of the present invention includes (i) a sensor substrate which functions as a photoelectric transfer element having a photodetecting TFT and a pixel capacitor and (ii) a driving IC for applying a voltage to a gate electrode of the photodetecting TFT so as to drive the photodetecting TFT into an ON state or an OFF state. The driving IC applies a voltage, whose polarity is opposite to average polarity of a voltage making the photodetecting TFT in the OFF state, to the gate electrode of the photodetecting TFT in an arbitrary period. Thus, it is possible to provide the image reading device which can suppress variation of a photodetecting TFT property (resistance value) which is observed in a short time.

  • Publication number: 20070238922
    Abstract: A driving signal is supplied from a transmission block to a magnetic-field generating element arranged on either one of an inside of an endoscope insertion portion and an outside of an endoscope. A magnetic field generated by the magnetic-field generating element is detected by a magnetic-field detecting element arranged on the other and the signal is received by a receiving block. For the signal from the receiving block, control processing including processing for calculating the shape of the endoscope insertion portion is carried out from position information of the magnetic-field generating element or the magnetic-field detecting element arranged inside the endoscope insertion portion. The receiving block provided with an amplification circuit for at least amplifying the signal detected by the magnetic-field detecting element is formed separately from the transmission block and the control block.
