Abstract:
An operation device for an into-bore introduction device, includes: a projecting portion formed to project from a grasping section in a radial direction to a longitudinal axis of the grasping section, in a surface between a surface on which a bending operation knob is disposed and a surface on which operator's palm abuts to grasp the grasping section, in the grasping section; a pressing switch disposed on the projecting portion; and an inclined surface formed distantly by as much as a predetermined distance from the pressing switch, and in which an amount of the inclined surface to project outside in the radial direction is decreased on an insertion section side of the projecting portion.
Abstract:
In a surgical treatment instrument, a probe extending in a longitudinal axial direction is inserted through a sheath, and each of sheath components, in the sheath, is divided from a neighboring sheath component at a dividing plane along the longitudinal axial direction. A flow of liquid to a proximal side in an inside of the sheath is prevented by a first seal portion. In a divided part between each of the sheath components and the neighboring sheath component, liquid-tight is kept by the second seal portion, and thereby a flow of the liquid to the proximal side is prevented.
Abstract:
A cell counting device for counting the number of cells in a sample includes: an accommodation portion that accommodates, in a removable manner, at least a part of a holding member for holding the sample; and a display unit configured to display information including a result of counting of the number of cells. The display unit has a screen inclined with respect to a bottom of the cell counting device. The bottom is configured to be in contact with a placement surface on which the cell counting device is placed. The display unit is provided between the accommodation portion and the bottom.
Abstract:
An upright microscope includes: a stage on which a specimen is placed; a revolver configured to hold a plurality of objective lenses and enable each objective lens on an observation optical axis to be switched by rotating an operation collar; a lens barrel including an optical system; a microscope body including a base, a stand that stands on a back side of the base and holds the stage, and an arm that is supported by the stand, extends toward a font side of the upright microscope, and includes a top part to which the lens barrel is attached and a bottom part to which the revolver is attached; and a finger hooking part that is positioned between the revolver and a lower part of the lens barrel and is for placing any of hand fingers other than a thumb of an observer when rotating the operation collar.
Abstract:
An endoscope system includes: a drive cable; an endoscope that has a bending portion that is capable of bending and is driven by the connected drive cable; a drive device that electrically drives the connected drive cable; a trolley equipped with the drive device; a stand that connects the drive cable and the endoscope and is capable of being installed at a position away from the trolley; and an operation device that is communicably connected to the drive device and attached to the stand.
Abstract:
An endoscope includes a universal cord which is connected to an operation section at one end thereof and which is configured to connect an external device to the operation section; a first switch which is disposed at about the same position as a connecting position to the universal cord along a longitudinal axis of the operation section; and a second switch which is disposed on a side opposite to the insertion section via the first switch along the longitudinal axis of the operation section, and which is formed to be higher than the first switch in a direction perpendicular to the longitudinal axis.
Abstract:
An endoscope includes a grasp section. The grasp section includes: a first surface adjacent, in the longitudinal axis, to a surface where the bending operation knob is provided, a protruding portion radially outwardly protruding to the longitudinal axis at a position adjacent to the first surface around the longitudinal axis, a first inclined surface provided on the protruding portion at a side adjacent to the first surface and inclined to the first surface, and a second inclined surface which is provided, on the protruding portion, at a side opposite to the first inclined surface across the protruding portion, and which is inclined to the first surface.
Abstract:
An operation device for an into-bore introduction device, includes: a projecting portion formed to project from a grasping section in a radial direction to a longitudinal axis of the grasping section, in a surface between a surface on which a bending operation knob is disposed and a surface on which operator's palm abuts to grasp the grasping section, in the grasping section; a pressing switch disposed on the projecting portion; and an inclined surface formed distantly by as much as a predetermined distance from the pressing switch, and in which an amount of the inclined surface to project outside in the radial direction is decreased on an insertion section side of the projecting portion.
Abstract:
A treatment instrument includes a grip and a handle. The grip is provided in an operation unit. The grip includes a first surface and a second surface provided back to back. The handle provided in the operation unit on a distal end side of the grip. The handle moves to the distal end side and the proximal end side relative to the grip. At least one of the first surface and the second surface is provided with a protrusion.
Abstract:
An operation device for an into-bore introduction device, includes: a grasping section connected to a proximal portion of an insertion section to be inserted into a bore, and is to be grasped by an operator to operate the insertion section; a bending operation knob disposed on the grasping section and bends a bending portion of the insertion section; a projecting portion formed to project from the grasping section in a direction radial to a longitudinal axis of the grasping section, in a surface between a surface on which the bending operation knob is disposed and a surface on which operator's palm abuts to grasp the grasping section, in the grasping section; and an inclined surface inclined toward the insertion section on an insertion section side of the projecting portion.
