Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultrasonic probe for inspecting the internal structure of a subject, and more particularly to an ultrasonic probe suitable for performing a laparotomy. is there.

(Prior art)

The basic components of a conventional intraoperative ultrasonic probe include a transducer for transmitting and receiving ultrasonic waves, a cable for transmitting and receiving electric signals, and a grip member for an operator to hold a probe. ing. These are inspection purpose, inspection department,
There are various kinds of intraoperative ultrasonic probes having various shapes and sizes in a front surface portion, a back surface portion, a deep portion, a narrow portion, and the like.

[Problems to be solved by the invention]

However, in the conventional intraoperative ultrasonic probe,
Depending on the purpose of the examination and the part to be examined, the configuration and the exchange work of the exchange part of several types of intraoperative ultrasonic probes become complicated,
There is a problem that various intraoperative ultrasonic probes are stained.

In addition, the conventional intraoperative ultrasonic probe has a large shape when inserted into the back side of the deep organ 12, as shown in FIG. 8, and the intraoperative ultrasonic probe 10 is pinched with the finger 11. Therefore, there is a problem that the operation is difficult because the intraoperative ultrasonic probe 10 cannot be firmly held.

The present invention has been made to solve the above problems.

An object of the present invention is to provide an ultrasonic probe that can be used for an intraoperative inspection of any part by using one type of ultrasonic probe.

The above and other objects and novel features of the present invention are as follows.
It will become apparent from the description of the present specification and the accompanying drawings.

[Means for solving the problem]

In order to achieve the above object, the present invention provides an ultrasonic probe, in which a grip member is detachably provided on a back surface of an ultrasonic transmission / reception unit of an ultrasonic probe body, and fingers ( Or a groove or a hole to be held by being sandwiched or inserted by a fingertip), the grip member is extended toward the cable side from the ultrasonic probe main body, and curved in the grip extension direction.

[Action]

According to the above-described means, the ultrasonic probe is reduced in size by removing the grip member. Furthermore, by providing a groove or a hole in the left-right direction of the grip member and extending it backward, it is possible to pinch it with a finger (or fingertip). Accordingly, the ultrasonic probe can be inserted into a deep part and a narrow part of the ultrasonic probe, and there is no need to replace the ultrasonic probe according to the inspection purpose.

Further, since the grip member is extended toward the cable side from the ultrasonic probe main body and curved in the grip extension direction, a scan looking up from the lower side of the target organ can be performed, so that the diagnostic area is enlarged. be able to.

(Example of the invention)

Hereinafter, an embodiment of the present invention will be specifically described with reference to the drawings.

In all the drawings for describing the embodiments, components having the same function are denoted by the same reference numerals, and their repeated description will be omitted.

FIG. 1 is a perspective view showing a schematic configuration of an ultrasonic probe according to one embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along line AA of FIG.

As shown in FIGS. 1 and 2, the ultrasonic probe main body 1 of the present embodiment includes a vibrator 2 for transmitting and receiving ultrasonic waves, and a cable 3 for transmitting and receiving its electric signals. Then, as shown in FIG. 2, a concave portion is provided on the ultrasonic probe main body 1 and a convex portion is provided on the grip member 4 side, so that the ultrasonic transmitting and receiving portion (vibrator 2) of the ultrasonic probe main body 1 A grip member 4 is detachably attached to the back surface using its elasticity. The shape of the grip member 4 extends from the ultrasonic probe main body 1 toward the cable 3 and is curved in the grip extension direction. Further, the grip member 4 is provided with grooves (or holes) 4A which are held on the side surfaces facing each other with fingers (or fingertips).

The grip member 4 is formed by plastic molding (for example, polycarbonate molding) using a mold, and is extended from the ultrasonic probe main body 1 to the cable 3 side.

The grip member 4 has a curved portion 4B.

As shown in FIG. 1 and FIG. 3 (right side view of FIG. 1 as viewed from the cable exit direction), the grip member 4
The groove 4A is a C-shaped recessed groove provided on the left and right sides of the grip member 4. By sandwiching the C-shaped groove 4A with the finger (or fingertip) of the operator, the ultrasonic probe main body 1 is firmly held even when the organ is mounted on the surface and inserted into a deep part.

Also, as shown in FIG. 4 (a plan view of the ultrasonic probe of FIG. 1 as viewed from the ultrasonic receiving side), the ultrasonic probe main body 1 is provided at an end of the cable 3. The connector 5 is connected to an ultrasonic tomography apparatus 6. 4C is a width dimension of the grip member 4, and the width dimension 4C is formed thin.

As can be understood from the above description, according to the present embodiment, as shown in FIG. 5 (a diagram showing the actual use state of the ultrasonic probe of the present embodiment with the grip member 4 removed). To
By using it with the grip member 4 removed, it is possible to reduce the size, operate with a finger (or fingertip) 11, and operate with a fine portion of the surface of the organ 12.

Also, as shown in FIG. 6 (a diagram showing the usage state of the ultrasonic probe on the organ surface in FIG. 1), the finger (or fingertip) 11 sandwiches the groove 4A of the C-shaped recess of the grip member 4. Used in.
Thereby, holding of the ultrasonic probe can be facilitated.

Also, as shown in FIG. 7 (a diagram showing the use state of the ultrasonic probe in the deep part of the organ in FIG. 1), the deep part and the back part of the organ 12 and the narrow part between the organs 12 and the like are used. When used in a part, the groove 4A of the C-shaped hollow of the grip member 4 is sandwiched between fingers (or fingertips) 11, and the bending of the curved portion 4B is used.
Since the ultrasonic probe main body 1 can be firmly held even if it reaches the deepest part and the deepest part and is narrow, the operation can be performed smoothly.

As can be understood from the above description, according to the present embodiment, for example, during laparotomy, the C of the grip member 4 attached to the ultrasonic probe main body 1 may be adjusted according to the purpose of examination at a deep part and a narrow part. By sandwiching the groove 4A of the hollow shape with the finger (or fingertip) 11, the holding property of the ultrasonic probe main body 1 can be improved.

Further, by making the grip member 4 detachable from the ultrasonic probe main body 1, it is possible to reduce the size and inspect small parts.

As a result, the operator can perform various tests during a laparotomy with one ultrasonic probe without using various ultrasonic probes depending on the test conditions, thereby improving the test efficiency. be able to.

Further, since the grip member 4 is extended from the ultrasonic probe main body 1 to the cable 3 side and curved in the grip extension direction, it is possible to perform a scan looking up from the lower side of the target organ. Can be expanded.

As mentioned above, although the present invention was explained concretely based on an example, the present invention is not limited to the above-mentioned example.
It goes without saying that various changes can be made without departing from the scope of the invention.

〔The invention's effect〕

As described above, according to the present invention, the ultrasonic probe can be inserted into the deep part and the narrow part, and according to the inspection purpose, there is no need to replace the ultrasonic probe, Since various kinds of examinations during laparotomy can be performed with the ultrasonic probe, examination efficiency can be improved.

Further, since the grip member is extended toward the cable side from the ultrasonic probe main body and curved in the grip extension direction, a scan looking up from the lower side of the target organ can be performed, so that the diagnostic area is enlarged. be able to.
