Medical imaging equipment

Abstract

To provide an image diagnostic device capable of reducing a work load on a medical expert and an operator required for checking how a medical instrument inserted into a living body lumen is used.SOLUTION: A control part 300 of an image diagnostic device 10 executes a first notification operation for notifying that an imaging unit 145 is moving backward while the imaging unit is moving backward when executing first display control, and executes a second notification operation for notifying that the imaging unit is advancing while the imaging unit is advancing when executing second display control. The control part starts a reciprocating operation mode from a state that the imaging unit is arranged at an advance limit position De in a sheath 110.SELECTED DRAWING: Figure 5

Claims

1. A diagnostic imaging catheter comprising: a sheath that can be inserted into a biological lumen; an imaging shaft that can move forward and backward along the axial direction of the sheath and has an imaging unit at its tip for acquiring a tomographic image of the biological lumen; and a hub located on the proximal end side of the sheath; A drive device that can be connected to the hub of the imaging catheter and drives the forward and backward movement of the imaging shaft, It comprises the drive device and the control unit which controls the operation of the imaging unit, The control unit performs a reciprocating motion mode in which it moves the imaging unit backward one or more times and forward one or more times between the forward limit position and the backward limit position in the axial direction. The control unit performs a first display control in the reciprocating motion mode, which displays a first tomographic image acquired while the imaging unit is retracting on the display device in synchronization with the retraction of the imaging unit, and a second display control, which displays a second tomographic image acquired while the imaging unit is advancing on the display device in synchronization with the advancing of the imaging unit. When the control unit performs the first display control, it performs a first notification operation to notify that the imaging unit is retracting while the imaging unit is retracting, and when the control unit performs the second display control, it performs a second notification operation to notify that the imaging unit is advancing while the imaging unit is advancing. The control unit starts the reciprocating motion mode from a state in which the imaging unit is positioned at the forward limit position within the sheath, in an image diagnostic apparatus.

2. The control unit, as the first notification operation, causes the display device to display an image indicating that the imaging unit is retracting. The image diagnostic apparatus according to claim 1, wherein the control unit causes the display device to display an image indicating that the imaging unit is moving forward as the second notification operation.

3. The medical imaging apparatus according to claim 1 or claim 2, comprising the operation of generating sound or voice as the first notification operation and the second notification operation.

4. The medical imaging apparatus according to any one of claims 1 to 3, comprising the operation of changing the color of a part of the display device as the first notification operation and the second notification operation.

5. The imaging diagnostic apparatus according to any one of claims 1 to 4, wherein the movement speed of the imaging unit can be set in the range of 0.1 mm / s to 10 mm / s.
