  • Patent number: 7951074
    Abstract: An endoscope device is proposed for dealing with an erroneous operation of a surgeon. An endoscope device has an endoscope and a processor, wherein the endoscope has a switch unit and the processor has a CPU and an operating panel. In the event that the CPU of the processor detects that, of a first instruction signal transmitted from the switch unit and a second instruction signal transmitted from the operating panel, the instructions for performing the predetermined operation are not performed normally with one of the instruction signals, and instructions for performing an operation other than the predetermined operation is performed normally with the other instruction signal, the CPU stops the transmission of one of the instruction signals, and validates the operation content instructed by the other instruction signal.

  • Patent number: 6984206
    Abstract: An endoscope system consists mainly of: an endoscope having a solid-state imaging device and an objective optical system that converges an object image on said solid-state imaging device; and a signal processing unit that processes an image signal produced by the endoscope so as to produce a video signal. The objective optical system includes an optical phase modulation member. The optical phase modulation member exhibits a response of 0.2 or more derived from an optical transfer function relative to a spatial frequency on the solid-state imaging device determined based on the Nyquist theorem, that is, a Nyquist frequency, over a wider range of distances than a depth of field offered by an objective optical system not having the optical phase modulation member.

  • Patent number: 6636254
    Abstract: Using an endoscope system, a surgeon A holds an endoscope with a TV camera (hereinafter, an endoscope) and a therapeutic appliance such as forceps and carries out a surgical procedure while viewing a first monitor. A surgeon B holds a therapeutic appliance such as forceps and carries out the surgical procedure while viewing a second monitor. A video signal sent from the TV camera of the endoscope is fed to and processed by an image processing apparatus, and displayed on each of the first and second monitors. The image processing apparatus transfers the video signal sent from the endoscope to each of an image inverting circuit and a selector switch. The image inverting circuit inverts an image (laterally (to produce a mirror image), vertically, or vertically and laterally (180°)), and supplies a processed video signal to the selector switch.

  • Patent number: 6319197
    Abstract: A medical system having an endoscope probe intubated into a body, a signal processing circuit for processing a signal for the probe and an electric source circuit insulated from a commercial electric source. A part of the signal processing circuit connected to the probe is isolated by an isolation circuit to secure the safety. An impedance element is employed to prevent a malfunction by reducing an emission/permeation of noises. No adverse influence is thereby exerted on outside units.
