Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ultrasonic glove with good operability.Recently, with the development of ultrasonic diagnostic equipment, ultrasonic diagnostic equipment has been applied to various medical techniques.

For example, during surgery, an ultrasound beam is applied directly to the incised organ of the patient, and the resulting ultrasound tomographic image is monitored to confirm the lesion area to be excised, or during surgery. There are times when we consider surgical strategies to respond to sudden changes in a patient's condition. In such cases, in the conventional single-party ultrasound system, the ultrasound emitting part 1 and the gripping part 2 are integrated as a trap, as shown in Fig. 1, so when the incision of the patient is small or Even if the incision is large, if there is an organ that should be ultrasound scanned deeper than the incision surface, the surgeon's hand holding the ultrasound probe gets stuck and he is unable to touch the desired location. Sometimes. for example,
When the pancreas is the affected area, it is necessary to directly contact the pancreas located on the back side of the liver 111 exposed by opening the abdomen. However, it is very inconvenient to use the ultrasonic glove, and even if the grip part 2 is made smaller as shown in Fig. 2 and a small-sized ultrasonic glove is used, it is difficult for the operator to hold the ultrasonic glove. My hand gets stuck in the incision.

Also, l! Ultrasound cable 3 shown in Figure 2
Even if the cable 3 is flexible, it is possible to quickly and appropriately bring the ultrasound probe into contact with the predetermined position 11 of the pancreas. It is difficult.

This invention has been made in view of the above circumstances, and it is possible to make an incision and insert the device to the desired affected position K in the body without any trouble, and also to be able to perform ultrasonic scanning while contacting the body surface. It is an object of the present invention to provide an ultrasonic probe that is easy to operate at 1° without any trouble. Next, an embodiment of the present invention will be described with reference to the drawings.

Figure 3183 is a schematic cross-sectional view showing an embodiment of the present invention, and Figure 1114 is a perspective view showing the connecting portion between the main body and the part.

In the third aIK, the ultrasonic glove 10 includes a glove body 1.1 and a handle 12 that is detachably attached to the probe body 11.

The probe body 11 includes a backing material 14 and a backing material 14 in a casing 13 having a substantially rectangular parallelepiped shape as shown in FIG.
A large number of linear array type ultrasonic transducers 15 are arranged on the surface of the housing 13 so that the ultrasonic transducers 15 are exposed through an opening provided in the housing 13, and the exposed surface of the ultrasonic transducers 15 is The acoustic lens 16 is bonded to the. Then, the backing material 14, the ultrasonic vibrator 15, and the acoustic lens 1
6 constitutes an ultrasonic transducer part, and ultrasonic waves are emitted in the direction of the arrow in the M3WJ by the ultrasonic transducer 15.
This point is similar to that of a normal ultrasound probe.

The casing 13 is provided with a handle attachment part 17 which is located approximately in the center of the rectangular parallelepiped in the longitudinal direction and forms a predetermined angle, for example, approximately 135° t, with respect to the direction of the ultrasonic emission force. There are others. There is a 17g male screw on the outer periphery of the handle attachment part 17.
is provided, and the tip surface Kl of the handle portion 17 is provided! As shown in FIG. It is bent to form a substantially dogleg-shaped tubular member with a circular cross section, and one end of the tubular member is provided with a 7-tsunge 12 that abuts the distal end surface of the handle attachment portion 17, as shown in FIG. A concave portion 12h that engages with the positioning protrusion 17A is formed on the distal end surface of the flange 126 so as to face toward the center of the tubular object. Note that two recessed portions are provided symmetrically with respect to the axis of the recessed portions 12AU. Further, the ring 12dt is loosely fitted into the tightening ring 12d, which has a female screw 12C that is screwed into a male screw provided on the outer periphery of the handle portion 12ri and the handle attachment portion 17. Note that the concave portion 12 created in the 7 flange 125
The correlation between the position of the positioning protrusion 17AK and the position of the positioning protrusion 17 is that when the positioning protrusion 17AK and the recess @12A are fitted, the ultrasonic emission direction (jt!3 direction of the arrow) and the handle part It is preferable to appropriately determine the opening direction of the other end of the recess 12 so that it forms an angle of 900 degrees with the opening direction of the other end of the recess. Therefore, when attaching the handle to the handle attachment part 17, the handle should be 180 degrees from the center axis of the handle 12t.
°Rotate the positioning protrusion 17h to the other concave part 12k
When fitted, the handle 12 is attached to the glove body 11 so that the direction in which the ultrasonic waves are emitted and the opening direction of the other end of the handle 12 make a 180° angle. can be attached.

The conductive wires connected to the ultrasonic transducer 15 are collectively formed into a cable 18, which is pulled out through the mouth of the handle attachment part 17 and the pipe of the handle part 12, and connected to an ultrasound pseudo-diagnosis device (not shown). Next, let us explain the action of the ultrasonic wave [70-p10] having the above configuration.For example, let us simply conduct an ultrasonic scan by touching the body surface of a subject, for example, a patient. In this case, the ultrasonic probe 10
When using the glove body 11, if the handle 12 is attached to the glove body 11, the handle 12 will interfere with the ultra-f wave scanning K11l. ffjl!
Remove the cap, insert the cable 18, and keep the bottle handle 12 away. Then, grasp the glove body 11 and
Ultrasound scanning is performed by bringing the ultra-ftIL emission surface into contact with the patient's body.Also, when trying to directly ultrasound scan the pancreas located on the back side of the liver, which is exposed through the patient's abdomen, For example, the direction in which the ultrasonic waves are emitted and the direction in which the other end of the handle 12 opens are at 180°.

Fit the positioning protrusion 177 into the recessed part 12, and tighten by connecting the handle attachment 1117 and the handle part 12 with the ring 124.In that case, even if the belly 5O41JlllW is small.
1a - main body 11 [- tb large enough to be inserted into the incision
TL, the operator grasps the handle 1l112t- and the group body 111-1ffll! By appropriately inserting the hammer into the incision, for example, by abutting the ultrasonic emission surface of the pancreatic lIK ultrasonic drum 10, the surgeon's hand can be pressed against the incision site. This eliminates the inconvenience of not being able to perform ultrasonic scanning. In addition, when trying to insert the 7E1-p main body 11 between the diaphragm and the liver,
What is the ultrasonic emission direction and the opening direction of the other end of the handle 12? O'
It is convenient to attach the handle 12 to the glove body 11 in the manner shown in FIG. 1 because the probe body 11'li can be inserted horizontally.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above-mentioned example, but includes various modifications within the scope of the gist of the present invention. Needless to say, in the above embodiment, the handle is attached at approximately the center 11 in the longitudinal direction of the main body, and the shape of the entire ultrasonic pump when viewed from the top surface is approximately T-shaped. However, as a modified example, as shown in Figure 11g5, K, glove body 2
At one end in the longitudinal direction of the 1TV, it is removable as in the previous embodiment, and 90 mm is attached near the attachment point to the 1TV main body 21.

0-p2o is mentioned. In this modification as well, the cable 18 does not extend through the handle 22 until it reaches the fitting 5.

In addition, in the above embodiments and modified examples, the handle is bent at a certain angle and the length is i, but the angle at which the handle is folded may be arbitrary. bent tt
If the handle is made of a V xypul tube (which can maintain an o* shape), the handle can be bent into any desired angular shape by hand.

The above-mentioned invention KX has the following effects:
If you remove the MR9, you can not only place the glove body on the subject's body surface and perform ultra-f11 scanning without any trouble, but also attach the handle to the glove body to make small incisions in the subject. Insert the glove body into the body from the
It can be inserted in a heavy position, and the main body can be inserted into the body while keeping the hand in the incision, unlike conventional methods. If the handle S is bent at a predetermined angle depending on the location of ultrasound scanning inside the body, after inserting the main body from the incision, the handle can be easily moved to the desired position. According to this invention I/C, since the handle is detachable, it is a highly versatile ultrasonic probe that can perform ultrasonic scanning even on the body surface and at different locations inside the body. 0 that can provide four
