## Abstract

In a medical examination sight maintaining videoscope of the present invention, in a state where an examination attachment is attached, it becomes possible to position a scope tip-end section and an object to be examined in a positional relationship in which the scope tip-end section and the object to be examined are straightly aligned with a line of sight of the user. At this time, a monitor is situated at such a position that the user can look straight at the monitor and the line of sight of the user is avoided.

## Claims

### Claim 1

A medical examination sight maintaining videoscope making it possible to shoot and record an object to be examined and visualize the object to be examined on a monitor while maintaining the object to be examined within a sight, said videoscope comprising:
a plurality of types of examination attachments;
a scope main body to which the plurality of types of examination attachments are selectively attached; and
a scope tip-end section to be provided on each of the examination attachments, and can be inserted into the object to be examined or can be operated along the object to be examined, wherein
the scope main body includes:
an attaching section to which the plurality of types of examination attachments can selectively be attached,
a light source configured to illuminate the object to be examined,
an operation section provided with buttons configured to shoot and record the object to be examined,
a monitor including a display surface configured to visualize the object to be examined thereon, and
a grip section which can be gripped with fingers of the user,
in a state where the user grips the grip section with his or her fingers, the operation section includes a contour along a trajectory of fingertips, and the monitor is positioned in such a manner that the user can look straight at the monitor,
a part of the grip section on the upper side thereof in the direction of gravitational force is configured in such a manner as to bulge out of the grip section so that the grip section gripped by the user with his or her fingers does not slip off the fingers downwardly in the direction of gravitational force,
the monitor is positioned on the opposite side of the operation section, and the display surface of the monitor is positioned in such a manner as to face in a direction opposite to the operation section,
the scope tip-end section is positioned on the opposite side of the monitor, and is positioned on the upper side of the monitor and the operation section in terms of the direction of gravitational force,
the scope tip-end section is positioned in such a manner as to face in a direction opposite to the display surface of the monitor, and
in a state where the selected examination attachment is attached to the attaching section, it becomes possible to position the scope tip-end section and the object to be examined in a positional relationship in which the scope tip-end section and the object to be examined are straightly aligned with the line of sight of the user and, at this time, the monitor is situated at a position avoiding the line of sight of the user.
