Ultrasound diagnosis apparatus
View Patent ↗An ultrasound diagnosis apparatus having a display supported by an arm mechanism is provided. The arm mechanism has a first arm member and a second arm member. A turning mechanism is provided at a base end portion of the first arm member and a turning mechanism is provided at a working end portion of the second arm member. An upper end portion of the first arm member and a lower end portion of the second arm member form a connection section, and an intermediate turning mechanism is provided inside the connection section. Because the arm mechanism is gently curved over its entire structure, no excessive load is applied to the cable passing inside the arm mechanism. The cable extends in the connection section along an outer route having a gentle radius of curvature.
1. An ultrasound diagnosis apparatus comprising:
a base member;
a display which is a flat panel display and which displays an ultrasound image; and
an arm mechanism provided on an upper side of the base member and between the base member and the display and which varies a position of the display while holding the display,
wherein the arm mechanism comprises:
a first arm member supported by the base member,
a second arm member supported by the first arm member, and
an intermediate turning mechanism provided at a connection section between the first arm member and the second arm member;
a cable reaching the display from the base member passes through an inside of the first arm member and the second arm member; and
a bent portion comprising an upper end portion of the first arm member and a lower end portion of the second arm member has a U shape in a state of an original position when a turning angle of the intermediate turning mechanism is 0°,
wherein the upper end portion of the first arm member and the lower end portion of the second arm member respectively have a gently curved shape, and
wherein the upper end portion of the first arm member and the lower end portion of the second arm member are connected via a horizontal rotation surface in a manner that the first arm member is not vertically movable with respect to the second arm member, and the second arm member is not vertically moveable with respect to the first arm member, and the upper end portion of the first arm member and the lower end portion of the second arm member have a mirror image symmetric shape with respect to the horizontal rotation surface in the state of the original position, and
wherein the first arm member comprises:
a slanted portion which extends from the base member toward a slanted upward direction and has a slanted axis; and
a gently curved portion which connects between the slanted portion and the upper end portion and has an axis which transitions from a slanted state to a horizontal state.
2. The ultrasound diagnosis apparatus according to claim 1 , wherein
one of the upper end portion and the lower end portion has a J shape and the other one of the upper end portion and the lower end portion has a horizontally inverted J shape.
3. The ultrasound diagnosis apparatus according to claim 2 , wherein
each of the upper end portion and the lower end portion has a circular horizontal cross section; and
the intermediate turning mechanism is built in across both of the upper end portion and the lower end portion.
4. The ultrasound diagnosis apparatus according to claim 1 , further comprising:
a lock mechanism which locks an operation of the intermediate turning mechanism.
5. The ultrasound diagnosis apparatus according to claim 1 , further comprising:
a lower turning mechanism provided at a base end portion of the first arm member and connected to the base member; and
an upper turning mechanism provided at a working end portion of the second arm member and which supports the display.
6. An ultrasound diagnosis apparatus, comprising:
a base member;
a display which is a flat panel display and which displays an ultrasound image; and
an arm mechanism provided between the base member and the display and which varies a position of the display while holding the display, wherein
the arm mechanism comprises:
a first arm member supported by the base member,
a second arm member supported by the first arm member, and
an intermediate turning mechanism provided at a connection section between the first arm member and the second arm member;
a cable reaching the display from the base member passes through an inside of the first arm member and the second arm member; and
a bent portion comprising an upper end portion of the first arm member and a lower end portion of the second arm member has a U shape in a state of an original position when a turning angle of the intermediate turning mechanism is 0°,
wherein the upper end portion of the first arm member and the lower end portion of the second arm member are connected via a horizontal rotation surface in a manner that the first arm member is not vertically moveable with respect to the second arm member, and the second arm member is not vertically moveable with respect to the first arm member, and the upper end portion of the first arm member and the lower end portion of the second arm member have a mirror image symmetric shape with respect to the horizontal rotation surface in the state of the original position, and
wherein the first arm member comprises:
a slanted portion which extends from the base member toward a slanted upward direction and has a slanted axis; and
a gently curved portion which connects between the slanted portion and the upper end portion and has an axis which transitions from a slanted state to a horizontal state.
7. The ultrasound diagnosis apparatus according to claim 1 , wherein the cable passes through the bent portion along an outer route which is displaced in the horizontal direction from a center axis of vertical rotation within the bent portion.
