Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an ultrasonic probe used in medical diagnostic equipment.

BACKGROUND OF THE INVENTION In recent years, with the spread of ultrasonic diagnostic apparatuses that perform diagnosis using ultrasonic waves, the number of operators handling them has also increased.

For this reason, the ultrasonic probes used in ultrasonic diagnostic equipment are required to be small, lightweight, and easy to hold, with good operability. An anti-slip strap made of an elastic material such as rubber is provided at the bottom of the ultrasound probe body a, so that the ultrasound probe body a can be grasped reliably.

In other words, in the case shown in FIG. 3(a), a groove f is formed all around the outer periphery of the joint between the upper case C and the lower case d of the case e consisting of the upper case C and the lower case d. The anti-slip band is fitted into the groove f by utilizing the elasticity of the anti-slip band.

In addition, in the case shown in FIG. 3 (b), a protrusion g is provided on the outer periphery of the lower case d, which is slightly below the joint between the upper case C and the lower case d, and extends over the entire circumference. The lower edges of the anti-slip straps are locked, and the gaps between the anti-slip straps of the upper case C and the lower case d are adhered with adhesive tape or the like.

Problems to be Solved by the Invention However, when making a diagnosis using an ultrasound probe, a water-soluble gel or the like is used to improve the acoustic coupling between the acoustic lens h and the skin. Therefore, when using the conventional ultrasonic probe body A for a long period of time, water-soluble gel and other substances may build up on the anti-slip band when using the conventional ultrasonic probe body A. It had the disadvantage that it entered the inside and came off more easily than the case e under the anti-slip band.

The present invention was made to improve the above drawbacks, and
It is an object of the present invention to provide an ultrasonic probe with a simple structure in which an anti-slip band does not easily come off from a case.

Means for Solving the Problems In order to achieve the above object, the present invention has a dovetail groove on the outer circumferential surface of the case of the ultrasonic probe body, which is narrow on the opening side and wide on the bottom side. A fitting groove is formed, and an anti-slip band having approximately the same cross-sectional shape as the fitting groove is tightly fitted into the fitting groove.

Effects of the Invention The present invention has the above-described structure, so that even if the ultrasonic probe is operated with a hand covered with water-soluble gel, etc., the ultrasonic probe is prevented from entering the inside of the anti-slip band. To prevent the anti-slip band adhered to the child body from peeling off, and to prevent the anti-slip band from falling off from the ultrasonic probe by fitting the anti-slip band to the dovetail-shaped fitting groove. Because it is possible to
Good operability can be obtained over a long period of time.

Embodiment An embodiment of the present invention will be described in detail with reference to the drawings shown in FIGS. 1 and 2.

FIG. 1 is a perspective view of the ultrasonic probe body 1, and FIG. 2 is a view of the same side.
The case 2 includes a lower case 2b and a lower case 2b.

A cable 3 for connecting to an ultrasonic diagnostic device (not shown) extends from the top of the case 2, and a fitting groove 4 is provided along the entire circumference of the joint between the upper case 2a and the lower case 2b. is formed.

The fitting groove 4 is a dovetail groove in which the width on the bottom side is wider than the width on the opening side, and both side surfaces 4a connecting the opening and the bottom side are formed.
has a reverse slope.

By fitting the anti-slip band 5 into the fitting groove 4, the upper case 2a and the lower case 2b are integrated.

The anti-slip band 5 is annularly formed of an elastic material such as rubber, and has a trapezoidal cross section so as to tightly fit into the fitting groove 4.

Further, the anti-slip band 5 is fitted into the fitting groove 4 whose inner surface is coated with adhesive by utilizing its own elasticity, and
The wall thickness is set so that when fitted into the fitting groove 4, the upper surface slightly protrudes from the outer peripheral surface of the upper case 2a, as shown in FIG.

The surface of this anti-slip band 5 is formed with many irregularities to make it difficult to slip.

Next, to explain the operation, the ultrasonic probe main body 1 configured as described above is operated by grasping the anti-slip band 5, but water-soluble gel, disinfectant, alcohol, etc. to improve acoustic bonding properties are Even if it adheres to the inside of the anti-slip band 5, it will not enter the inside of the anti-slip band 5 because it is tightly fitted into the fitting groove 4 of the anti-slip band 5.
Moreover, even if the slip prevention band 5 enters the fitting groove 4, the fitting groove 4 is a dovetail groove, so the anti-slip band 5 will not come off from the fitting groove 4.

In the above embodiment, the fitting groove 4 is formed around the entire circumference of the joint between the upper case 2a and the lower case 2b, and the anti-slip band 5 is fitted into this fitting part 4. When the fitting groove 4 is formed only in the lower case 2b, the upper case 2a
Alternatively, the same function can be obtained even if the fitting groove 4 is not provided around the entire circumference of the lower case 2b but is provided only in a portion thereof.

Effects of the Invention As detailed above, the present invention forms a dovetail-shaped fitting groove that is narrow on the opening side and wide on the bottom side on the outer circumferential surface of the case of the ultrasonic probe main body. Since the anti-slip band is tightly fitted into this fitting groove, even if the ultrasonic probe is operated with a hand covered with water-soluble gel, the water-soluble gel etc. will not get inside the anti-slip band. This can prevent the anti-slip band attached to the ultrasonic probe body from peeling off, and the fitting of the anti-slip band with the dovetail-shaped fitting groove allows ultrasonic detection of the anti-slip band. Since it is possible to prevent the contactor from falling off, good operability can be obtained over a long period of time.
