[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a probe holding device for holding a probe used in an ultrasonic diagnostic apparatus.

[0002]

2. Description of the Related Art A conventional probe holding device will be described with reference to FIG. FIG. 4A is a side view of the ultrasonic diagnostic apparatus, and FIG. 4B is a side view of the probe holding device. In FIG. 4, reference numeral 101 denotes an apparatus main body of the ultrasonic diagnostic apparatus, 102 denotes a probe holding device, and 103 denotes a probe. The probe 103 is connected to the elongated relay shaft 10.
4 has an ultrasonic transmission / reception unit 105 at one end, and the relay shaft 1
04 has a grip portion 1 having a larger diameter than the relay shaft portion 104.
06 from the end of the grip 106.
A cable 107 for electrical connection to the cable is drawn out. The probe holding device 102 has an arm-like extension on the front surface of the device main body 101, and is provided continuously with a hole 108 for inserting the grip portion 106 of the probe 103 from above and a lower portion of the hole 108, A support protrusion 109 for supporting the lower end of the grip portion 106; and a slit 11 for vertically communicating the hole portion 108 and the support protrusion 109 from the side surface.
Has zero.

In the above conventional example, the probe holding device 1
02 to hold the probe 103, the probe 1
With the ultrasonic transmission / reception unit 105 up and the grip unit 106 down, the cable 107 of the probe 103 is inserted into the slit 110 from the side, and the grip unit 106 is inserted from above the hole 108 and supported. The projection 109 is held.

[0004]

However, in the above-described conventional probe holding apparatus 102, since the ultrasonic transmission / reception unit 105 of the probe 103 is held up and the grip unit 106 is held down, the ultrasonic transmission / reception unit 105 is exposed. Then, when the apparatus main body 101 was moved, the ultrasonic transmission / reception unit 105 sometimes hit an obstacle and was damaged. Further, since only the lower end of the grip portion 106 is held, there is a problem that the holding becomes unstable.

The present invention solves such a conventional problem, and provides a probe holding device capable of reliably protecting the ultrasonic transmission / reception section of the probe and holding the probe stably. Aim.

[0006]

According to the present invention, in order to achieve the above object, at least a cylindrical portion for accommodating at least an ultrasonic transmitting / receiving section of a probe and an upper portion for holding a grip portion of the probe are provided. It has a holding portion. A slit for inserting the probe from the lateral direction may be provided in the lower cylindrical portion and the upper holding portion.

[0007]

Therefore, according to the present invention, at least the ultrasonic transmission / reception unit is housed in the cylindrical portion of the probe holding device, and the probe is gripped while the probe is held with the gripping portion up and the ultrasonic transmission / reception portion is down. By holding the unit on the holding unit, the ultrasonic transmission / reception unit can be reliably protected and the probe can be stably held.

[0008]

FIG. 1 shows a first embodiment of the present invention.
FIG. 1A is a cross-sectional view of a probe holding device holding a probe, and FIG. 1B is a perspective view illustrating an appearance of the probe holding device. In FIG. 1, reference numeral 1 denotes a probe, which has an ultrasonic transmission / reception unit 3 at one end of an elongated relay shaft 2 and a grip 4 having a larger diameter than the relay shaft 2 at the other end. A cable 5 for electrically connecting to an ultrasonic diagnostic apparatus is drawn out from an end of the cable 4. Reference numeral 11 denotes a probe holding device, which comprises a cylindrical tube portion 12 and a cylindrical holding portion 13 having the same diameter which is continuous with an upper portion of the tube portion 12, and a portion excluding a lower end portion 12a of the tube portion 12. A slit 14 that is continuous in the longitudinal direction is provided on a side surface of the holding unit 13. A support protrusion 15 is provided on the inner peripheral surface of the holding portion 13 in the circumferential direction. Further, the probe holding device 11 is locked on the side surface of the cylindrical portion 12 and the holding portion 13 opposite to the slit 14 with the side surface of the device main body 21 of the ultrasonic diagnostic apparatus as shown in FIG. Locking projections 16 and 17 are provided.

Next, the operation of holding the probe 1 in the probe holding device 11 in the above embodiment will be described. In FIG. 1, the probe 1 has an ultrasonic transmission / reception unit 3 with the grip unit 4 up and the ultrasonic transmission / reception unit 3 down.
After the relay shaft portion 2 is inserted into the cylindrical portion 12 and the holding portion 13 from the slit 14 in the lateral direction, and the grip portion 4 is lowered, the grip portion 4 is held in contact with the support protrusion 15 of the holding portion 13. The ultrasonic transmission / reception unit 3 is accommodated in a non-contact state in a lower portion 12 a of the cylindrical portion 12 having no slit 14.

As described above, according to the above embodiment, the lower cylindrical portion 12 for housing the ultrasonic transmitting / receiving portion 3 and the relay shaft portion 2 of the probe 1 and the upper holding portion for holding the grip portion 4 of the probe 1. 13 is provided with a slit 14 for inserting the probe 1 from the lateral direction, so that the attachment and detachment of the probe 1 can be easily performed, and the protection of the ultrasonic transmission / reception unit 3 can be ensured, and the probe 1 is stabilized. It can be kept in place.

FIG. 3 shows a second embodiment of the present invention, which differs from the first embodiment in that an independent tube portion 12 'is omitted by omitting a portion between the tube portion 12 and the holding portion 13. That is, the holding unit 13 'is used. Therefore, the cylindrical portion 1 in this embodiment is
The 2 ′ and the holding unit 13 ′ are specialized in the function of protecting the ultrasonic transmission / reception unit 3 of the probe 1 and the function of holding the grip unit 4, respectively. It can be manufactured at low cost.

The present invention can be variously modified.
For example, the holding portions 13 and 13 ′ may be made of a material having spring properties without providing the support protrusions 15, and the grip portion 4 may be fitted from the side. Alternatively, the cylindrical portions 12 and 12 ′ may house only the ultrasonic transmitting / receiving section 3.

[0013]

According to the present invention, as is apparent from the above embodiment, the lower portion has a cylindrical portion for accommodating at least the ultrasonic transmitting / receiving portion of the probe, and the upper portion has a holding portion for holding the grip portion of the probe. With the probe with its gripping part up and the ultrasonic transmitting and receiving unit down, the ultrasonic transmitting and receiving unit is housed in the cylindrical part, and the gripping part is held by the holding part, The ultrasonic transmission / reception unit can be reliably protected, and the probe can be stably held.
