摘要： A cover device which is removably fitted over an endoscope to cover an insert part of the endoscope and a control part connected to the proximal end of the insert part. The cover device includes a tubular sheath for covering the insert part so as to isolate it form the outside, and a control part cover for wrapping the control part. The control part cover is separate from the sheath and spreadably provided in contiguity with the proximal end of the sheath. In addition, a fluid supply tube is disposed such that one end portion of the tube extends through the sheath to communicate with the distal end of the sheath. The other end portion of the tube extends from the proximal end of the sheath along the outside of the control part cover.

摘要： A sheath device for an endoscope comprises a sheath which is inflatable with a gas that is pumped into the inside of the sheath to allow an insert tube of the endoscope to be covered. A sheath cover, formed in the shape of a tube, surrounds the sheath with a space left therebetween to control overinflation of the sheath. A portion of the sheath cover, that surrounds the distal end portion of the sheath, is tapered toward the distal end of the sheath cover. A gas supply passage is provided for supplying a gas into the sheath to inflate it, and a gas pressure control device is provided with a bleeder which communicates with the gas supply passage and opens upwardly to the atmosphere. A ball valve is placed on the bleeder from the upper side thereof to close it.

摘要： A mold for forming a groove in a tube includes a split round bar having a groove extending in a substantially straight line along an axis thereof. The two halves of the split round bar are in contact with each other only at a pint at the bottom of the groove, so that the two halves may pivot with respect to each other about the contact point. A spacer bar is removably clamped between opposed inner surfaces of the two halves of the split round bar. When the spacer is removed, the groove in the round bar is slightly enlarged to provide clearance between the tube and each side wall of the groove to enable the round bar to be easily removed from the tube.

摘要： A bending control device of an endoscope for bending a bendable portion, formed at the distal end of the insert part of the endoscope, by manual operation of a control part connected to the proximal end of the insert part is provided. The bending control device has an up and down bending control knob rotatably and detachably provided on the control part to control bending of the bendable portion in upward and downward directions. A right and left bending control knob is rotatably and detachably provided on the control part, in coaxially superposed relation to the up and down bending control knob, to control bending of the bendable portion in the rightward and leftward directions. An attaching and removing device is also provided for manually attaching and removing the two bending control knobs to and from the control part. Thus, the bending control knobs can be removed from the control part as desired for washing and disinfection or replacement with new bending control knobs.

摘要： An endoscope is provided with a sheath which is removably fitted over an insert tube to isolate it from the external environment. A plurality of channels are provided for passing fluids, each channel having an opening at one end near the distal end portion of the sheath and extending at the other end past the proximal end of the sheath. A channel connecting device is provided at the extending end portions of the channels. The channel connecting device is capable of simultaneously and detachably connecting at least two of the channels to respective channels in the endoscope through respective connecting conduits, which are provided in a control part of the endoscope. Respective end portions of the channels are disposed in substantially parallel relations to each other, and the connecting conduits are disposed in a direction which is perpendicular to the axes of the end portions of the channels. In addition, a packing is provided in an opening at the proximal end of the sheath which is movable in the radial direction of the sheath to enable the insert tube to be inserted into and removed from the sheath while the outer peripheral surface of the insert tube remains hermetically sealed.

摘要： A distal end part of an endoscope which is provided at the distal end of the insert part of the endoscope, comprising an illuminating window through which illuminating light is emitted, a viewing window disposed side by side with the illuminating window to take a light image into an objective optical system, and a single transparent cover continuously covering the respective surfaces of the illuminating and viewing windows, the cover being formed such that the wall thickness thereof is gradually changed at the portion thereof which extends between the illuminating and viewing windows. Accordingly, no illuminating light enters the visual field of the viewing optical system through the transparent cover and it is therefore possible to obtain a clear observation field of view which is free from a ghost or flare.
