BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultrasonic diagnostic treatment apparatus, and more particularly to an ultrasonic diagnostic treatment apparatus having an ultrasonic probe which is inserted into a body cavity to perform ultrasonic diagnosis and treatment.

[0002]

2. Description of the Related Art Conventionally, an ultrasonic diagnostic treatment probe (hereinafter, simply referred to as an ultrasonic probe) used in an ultrasonic diagnostic treatment apparatus for performing diagnosis and treatment by ultrasonic waves inserted into a body cavity is, for example, mechanical. In the scanning method, it is common that a scanning drive unit having a driving unit for rotating or linearly moving an ultrasonic transducer is connected to a base end of an insertion unit to be inserted into a body cavity and formed. .

[0003] In the case where the insertion section and the scanning drive section are directly connected and integrally formed as described above, the ultrasonic probe itself becomes large in size and large in weight.
It is extremely difficult to carry out diagnostic treatment while holding the ultrasonic probe.

[0004] Therefore, when performing diagnostic treatment using such an ultrasonic probe, the ultrasonic probe has been fixed to a probe holder, a stand, or the like.

[0005]

However, even if such a means is adopted, the position of the ultrasonic probe in the body cavity is still arbitrarily controlled according to the situation of diagnosis or treatment (treatment). There was a problem that it was difficult. Further, since the ultrasonic probe cannot be held and used at the time of diagnosis and treatment, there is also a problem that a portion where diagnosis and treatment can be performed is limited.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has as its object to provide a small and lightweight device which can be easily held and operated by an operator when performing diagnosis and treatment. Another object of the present invention is to provide an ultrasonic diagnostic treatment apparatus having a simple ultrasonic probe.

[0007]

To achieve the above object, an ultrasonic diagnostic and therapeutic apparatus according to the present invention comprises an ultrasonic transducer for diagnosis and treatment and a rotary transducer provided with the ultrasonic transducer at the tip. A probe comprising a force transmitting means, an insertion part comprising a casing means for accommodating the ultrasonic vibrator and the rotational force transmitting means and being inserted into a body cavity, and a grip part connected to a base end of the insertion part. A driving unit provided separately from the probe and having a rotational driving unit for generating a rotational force, and connecting the rotational driving unit of the driving unit and the rotational force transmitting unit of the probe to form the ultrasonic transducer. And a flexible torque transmitting means for rotating.

Therefore, in the ultrasonic diagnostic treatment apparatus according to the present invention, the probe including the insertion portion and the grip portion, and the drive portion having the rotation drive means are separately provided, and the flexible rotational force transmission is performed between the two. By being connected by means, the size and weight of the ultrasonic diagnostic treatment probe can be reduced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments. FIG. 1 is a schematic perspective view showing an ultrasonic diagnostic treatment apparatus according to the first embodiment of the present invention.

As shown in FIG. 1, this ultrasonic diagnostic treatment apparatus is provided with an insertion portion 4 to be inserted into a body cavity, and a grip which is disposed at a rear end of the insertion portion 4 and which is operated by an operator. Part 10
And the insertion section 4

And is constituted by.

A rigid shaft 5 serving as a rotating force transmitting means is inserted into the insertion portion 4, and the distal end of the rigid shaft 5 has a single-plate or single-plate concave surface shape for diagnosis and treatment. An ultrasonic vibrator 3 for generating an ultrasonic wave for performing the operation is provided.

As the ultrasonic vibrator 3, for example, a vibrator that is used for both diagnosis and treatment, a vibrator in which separate ultrasonic vibrators for diagnosis and treatment are integrally formed on the front and back sides, and the like are employed. The ultrasonic vibrator 3 may be an electronic scanning ultrasonic vibrator of a linear array type or the like, in addition to the above-described single-plate or single-plate concave shape.

A coupling 7 to which the base end of the rigid shaft 5 is connected and an encoder 8 for encoding the rotation of the coupling 7 are provided in the gripping portion 10. , Is connected to the coupling 7 via a pulley 9 and a belt wrapped around the pulley 9.

The grip 10 and the driving unit 2 are connected by a flexible shaft 6 which is a flexible torque transmitting means having flexibility. That is, one end of the flexible shaft 6 is connected to the coupling 7, and the other end is connected to a motor or the like (not shown) which is a rotation driving unit in the driving unit 2. Thereby, the rotational driving force generated by the driving unit 2 is transmitted to the coupling 7 via the flexible shaft 6 and is transmitted to the ultrasonic vibrator 3 via the rigid shaft 5 connected to the coupling 7. To be transmitted. The flexible shaft 6 is a flexible sheath 1
3 protected.

The drive unit 2 and the system body 12
Are connected by a cable or the like.

A cable for supplying drive power or the like from the drive unit 2 to the ultrasonic vibrator 3 also passes through the inside of the sheath 13, the grip unit 10, and the insertion unit 4. , Are not shown.

On the other hand, a sound transmission window (not shown) is provided at the distal end of the insertion portion 4 on the outer peripheral surface corresponding to the position where the ultrasonic transducer 3 is provided. An acoustic transmission medium (not shown) is filled between the ultrasonic transducer 3.

In the ultrasonic diagnostic treatment apparatus according to the first embodiment having the above-described configuration, when the flexible shaft 6 is rotated by the rotational driving force of the driving unit 2, the rotational driving force is applied to the cup in the grip unit 10. It is transmitted to the rigid shaft 5 via the ring 7 and rotates the rigid shaft 5. Accordingly, the ultrasonic transducer 3 is also driven to rotate in the same direction, so that rotational scanning by the ultrasonic transducer 3 becomes possible.

The drive unit 2 may be controlled by providing a control switch or the like on the grip unit 10 or by performing all controls on the system body 12 side.

As described above, according to the first embodiment, the large and heavy drive unit conventionally formed integrally with the ultrasonic probe is separated from the ultrasonic probe and separated. Since it is formed, the operator can grasp and operate the ultrasonic probe 1 when performing a diagnostic treatment, thereby contributing to an improvement in the operability of the ultrasonic diagnostic treatment apparatus.

It is possible to further reduce the size and weight of the apparatus itself, thereby improving the operability of the ultrasonic diagnostic treatment apparatus.

Further, since the ultrasonic probe 1 is reduced in size and weight, it is possible to arbitrarily move the ultrasonic probe 1 to a desired position when an operator grasps the ultrasonic probe 1 and performs diagnosis and treatment. Therefore, the degree of freedom and efficiency of diagnosis and treatment can be drastically improved.

By the way, in a conventional mechanical scan type ultrasonic diagnostic and therapeutic probe, a therapeutic ultrasonic transducer and a diagnostic ultrasonic transducer are provided integrally on the front and back or separately provided, and this ultrasonic transducer is used. Diagnosis and treatment are performed by rotating and scanning forward and backward.

In such a conventional ultrasonic probe, the ultrasonic transducers for diagnosis and treatment are provided integrally on the front and back sides. At the time of diagnosis, the ultrasonic transducer for diagnosis is rotated and scanned to perform ultrasonic observation. However, during treatment, the ultrasonic transducer for treatment is stopped so as to be directed to the target site and focused ultrasonic waves are emitted, so that diagnosis (observation) and treatment by ultrasonic waves cannot be performed simultaneously. There is.

In the case where the ultrasonic transducers for diagnosis and treatment are provided separately, a common drive mechanism for driving each ultrasonic transducer is used. It means that the image cannot be observed.

On the other hand, with an ultrasonic probe of the electronic scan type, a diagnostic image can be observed even during treatment, but the whole system becomes large, and the manufacturing cost and the maintenance cost of the user are large. There is a problem that it becomes.

Therefore, in a second embodiment of the present invention described below, the scanning mechanism in the above-described conventional mechanical scan type ultrasonic probe is improved so that diagnosis (observation) and treatment by ultrasonic waves are simplified. To provide an ultrasonic diagnostic treatment apparatus that can be performed at the same time, and to provide an ultrasonic diagnostic treatment apparatus that can perform treatment more efficiently and improve operability. The purpose is.

For this purpose, a therapeutic rotary drive system for driving the therapeutic ultrasonic transducer and a diagnostic rotary drive system for driving the diagnostic ultrasonic transducer are separately provided, whereby By driving the ultrasonic vibrator and the diagnostic ultrasonic vibrator separately, diagnosis (observation) and treatment can be performed simultaneously.

According to this, diagnosis (observation) by ultrasonic waves
