DESCRIPTION JPS54129785
Description 1, title of the invention
Ultrasonic glove
3. Detailed Description of the Invention The present invention relates to an ultrasonic probe for
an ultrasonic diagnostic apparatus in which a plurality of ultrasonic transducers are arranged
side by side on a support table in an IJ. Ultrasonic diagnostic apparatuses are classified into two
types, sector type and linear type, depending on the scanning method. The sector type is
juxtaposed in a row on the support base ttf? , A drive pulse is given from a pulsar to a large
number of ultrasonic transducers, and in this case, a delay time of the drive pulse is given by a
delay line to scan the ultrasonic beam emitted from the @ sound transducer in a fan shape and
receive circuit. It is received by Also, in the linear type, the output of a pulser that generates a
pulse for driving an ultrasonic imaging element arranged in a line is switched 1-nextly by a valley
switch of a switching circuit to shift the ultrasonic transducer to be driven. It scans the beam
linearly. In any of the above cases, ultrasonic waves are converted to pcs inside the subject,
electrical signal processing is performed, and a two-dimensional cross-sectional image of the
inside of the human body and EndPage: 1 are displayed on the CRT of the display device. It is.
Conventionally, tomograms obtained by an ultrasound examination apparatus are clinically used
for abdominal diseases, obstetrics area, heart diseases, 9 head diseases and the like. Hematoma,
calculi, also as types of diseases 4. It is used for various diagnoses such as pregnancy, uterus and
cubs, as well as malformations and two letters. It is necessary to know the size, shape, and the
like of the subject to be inspected, if such diagnosis is to be performed. However, it is necessary
to move the ultrasound glove on the contact surface of the subject in order to know the size and
shape of the object to be inspected which is three-dimensional because the display device can
only perform two-dimensional display. . In that case, it is difficult to make correspondence

between the previous image and the image obtained after moving the ultrasonic probe.
Therefore, it is not possible to know the exact size and shape of the object to be inspected. The
object of the present invention is made in view of the disadvantages of these conventional
devices, and in the case of displaying a cross inspection object 1iLl on a CRT of a display device,
the object to be inspected centering on any one point. An ultrasound glove for an ultrasonic
diagnostic apparatus which completely enables obtaining a multi-directional cross-sectional
image of an object. A round hole 2 is provided in the part, and a rotation center shaft 3 made of
resin is inserted into the 1 round hole 2. A radially protruding rod-4 is provided at an
intermediate portion of the rotation center shaft 3. The coil spring 5 is inserted into the circular
hole 2 above the stop 4 in the middle region of the rotation center shaft 3. The coil spring 5 is
fixed at the bottom I (received by the stopper plate 6) (the stopper plate 6 is fixed to the support
1).
Further, the spring retainer plate 7 is fixed to the above-mentioned rotation center shaft 3 и by
pressing it with a mesh plate 7 above the coil spring 5. The front ml stout (lock play for locking 4) 8'1 is connected to the support grate 9 by means of a helical spring lO. Also, in order to soften
the contact of the rotation center shaft 3 on the body surface of the test body, semi-spherical
rubber 11. Install Further, in order to allow the # 1 rotation center shaft rod 3 to be inserted and
removed, the upper end portion of the rotation center shaft rod 3 is covered with a cover 12
made of an elastic material at a portion pressed by the operator who operates the ultrasonic
probe. As attached to the support 1. A large number of ultrasonic transducers 16 are mounted in
at least one row on the contact surface of the support 1 with the body. The operation of the
ultrasound probe according to FIG. 1 is performed as follows. At the beginning of the diagnosis,
as shown in FIG. 2, the ultrasound glove support 1 is placed on the body surface of the subject
13 and a large number of superstructures arranged in a row on the contact surface of the
support 13 of the subject 13. The sound transducer 16 is driven. That is, an arbitrary cross
section 614 of the object to be inspected inside the object 13 is displayed on the display device
by the scan of the second time. It is shown in FIG. The scanning section center is on the
intersection line P of the # plane image 14 displayed on the display apparatus with the center
line 15 of the display apparatus. Between A and A in FIG. 4 is a scanning section, and the vertical
direction is the depth direction of the object 13. For diagnostic purposes, it may be desirable to
display a cross-sectional image at an arbitrary angle with respect to the cross-section $ 14
currently displayed on the display device at the position of the intersection line P of the arbitrary
cross-sectional image 14 of the test object is there. In that case, when the operator presses the
upper surface of the wax and the stick in FIG. 1 (-12, the central axis of rotation of the paper 9 is
moved downward, so that the stopper 4 is moved downward). The horizontal partial pressure of
the force applied by the operator acts on the contact surface with the lock plate 8, and the lock
plate 8 rotates in the right direction. After the stopper, the stopper 4 is inserted into the lock
plate 8 from the notch 9. As shown in FIG. As a result, the rotation center shaft 3 is locked at the
position moved downward. The state is shown in FIG. As a result, the subject 13 and the support

1 of the ultrasound glove are separated by a fixed distance, and therefore, as shown in FIG. 5,
without changing the scanning section center, the ultrasound probe Rotate the support l. When
the operator presses the upper end of EndPage: 2 cover 12 again at a place where it seems to be
a suitable rotational displacement, the stopper 4 provided on the rotation center shaft 3 moves
downward. Do.
Thereafter, the lock plate 8 is returned to the vertical position by the action of the torsion helical
spring 10, and the stopper 4 is pulled out of the lock plate 8 by the guide plate attached to the
lock plate 8, and the rotation center shaft 3 is rotated. The lock is released. Thus, the support 1
of the ultrasonic probe again contacts the body surface of the subject 13. Therefore, another
cross-sectional image having an arbitrary angle with respect to the cross-sectional image 14
displayed on the display device before moving the ultrasonic probe can be obtained by scanning
again. Other. In order to obtain the cross-sectional image as described above at another position
of the arbitrary cross-sectional image 14 of the object to be inspected, the ultrasonic probe is slid
on the surface of the object 130 so as to be desired. Align the position on center # 15 of the
display device. The subsequent operation is the same as described above. The cross-sectional
images obtained in this way are photographed respectively, and since the obtained photographs
have clear relative positional relationships, when the obtained cross-sectional images in multiple
directions are evaluated clinically, the examination Knowing the exact size and shape of the
object is intoxicating. Although the above-mentioned example was rotation about an axis
perpendicular to the body surface of the subject 13, in addition, as shown in FIG. As shown in
FIG. 7, the present invention is also applicable to pitching motion around the tip of the ninerotation center shaft 3 or the like. As another embodiment, by providing a detector for detecting
the rotational displacement of each motion, it is possible to quantitatively relate the displacement
angles of the cross sectional images in multiple directions centering on one point. Further, since
the semicircular ball rubber 11 is provided on the lost center of the rotation center shaft 3, it is
safe for the subject. As described above, when the ultrasonic glove according to the present
invention is applied to an ultrasonic diagnostic apparatus as described above, cross-sectional
images from multiple directions can be obtained with any one point of the object to be inspected
as a fixed point. Therefore, if the cross-sectional images obtained are comprehensively evaluated,
the three-dimensional evaluation of the inspection object, that is, the actual size of the inspection
object. It is possible to accurately know the form and is very useful in diagnosis for many types of
diseases.
