[0003] ところで、治療部位に当てた超音波プローブ力 の超音波の照射量が過大になると 、その部分が発熱して疼痛を感じたり、火傷を起こすなどの懸念を生じる。そのため、 こうした疼痛予防や火傷防止のために、治療中に施術者が絶えず超音波プローブを 広い範囲に動力さなければならな力つた。  [0003] By the way, when the irradiation amount of the ultrasonic wave of the ultrasonic probe force applied to the treatment site becomes excessive, the part is heated to cause a concern such as pain or burn. Therefore, in order to prevent such pain and burns, the practitioner had to constantly power the ultrasound probe to a wide range during treatment.
[0004] このような問題に対して、別な特許文献 2には、少なくともその一部の位置力 相互 に三次元的に変更自在となるように、複数の超音波振動子を平面状に配置すること で、生体の広い範囲に超音波を照射する際に、施術者への負担を軽減できる装置 が開示されている。さらにここでは、複数の超音波振動子を同時に駆動させたときに 、各振動子力 の音場が不必要に重なり合って、その部分で超音波の照射量が過大 になるのを防ぐために、それぞれ異なる駆動系により駆動される振動子群を巿松模 様に配置し、各振動子群を相互に逆のタイミングでオン Zオフ駆動させて、超音波の 照射量を平均化させる考えも示されて 、る。  [0004] With respect to such a problem, another patent document 2 arranges a plurality of ultrasonic transducers in a planar manner so that at least a part of position forces thereof can be changed three-dimensionally with each other. There is disclosed an apparatus capable of reducing the burden on the practitioner when applying ultrasonic waves to a wide area of a living body. Furthermore, here, when a plurality of ultrasonic transducers are driven at the same time, the sound fields of the respective transducer forces overlap each other unnecessarily, and in order to prevent the irradiation amount of the ultrasonic waves from becoming excessive at that portion, The idea is also shown that the transducer groups driven by different drive systems are arranged in a rhombus pattern, and each transducer group is driven on-off at opposite timings to average the irradiation amount of ultrasonic waves. It is.

発明の開示 発明が解決しょうとする課題 Disclosure of the invention Problem that invention tries to solve
[0005] 上記特許文献 2では、複数の超音波振動子を広範囲に配置することで問題の解決 を図っているが、超音波プローブ力 の超音波の照射量を平均化させたとしても、超 音波プローブを生体に沿ってある程度動力さなければ、やはり患者が疼痛を感じたり In Patent Document 2 above, the problem is solved by disposing a plurality of ultrasonic transducers in a wide range, but even if the amount of ultrasonic waves of ultrasonic probe force is averaged, it is If the acoustic probe is not powered to some extent along the body, the patient will still feel pain
、さらには火傷を起こす懸念を払拭できない。さらに、患者の治療部位が、例えばひ ざや腹など複数箇所に及んでいると、その分だけ超音波プローブを動かす範囲も広 がって、治療時間が長くなる問題を引き起こす。 And even can not eliminate the concern of causing burns. Furthermore, if the treatment site of the patient extends to a plurality of places such as the knee and belly, for example, the range in which the ultrasonic probe is moved is also extended by that amount, causing a problem that the treatment time becomes longer.
[0006] そこで本発明は、施術者がわざわざ超音波プローブを動力さなくても、生体の広い 範囲に適切な量の超音波を照射でき、治療時間を短縮できる超音波生体刺激装置 を提供することをその目的とする。 [0006] Therefore, the present invention provides an ultrasonic biostimulation apparatus capable of irradiating an appropriate amount of ultrasonic waves over a wide range of a living body without the need for the practitioner to power the ultrasonic probe, thereby shortening the treatment time. To that purpose.
課題を解決するための手段  Means to solve the problem
[0007] 本発明の超音波生体刺激装置は、複数の超音波振動子を平面状に配置し、これら の超音波振動子を生体に固定した状態で取付ける超音波プローブと、前記各超音 波振動子への駆動電力を生成する駆動手段と、前記超音波プローブから発する超 音波エネルギーが局部的に集中しな 、レベルで、前記駆動手段からの駆動電力を 複数の超音波振動子に対し切替えて供給する切替手段と、を備えている。 An ultrasonic biostimulation apparatus according to the present invention comprises an ultrasonic probe in which a plurality of ultrasonic transducers are arranged in a plane and these ultrasonic transducers are fixed to a living body, and each of the ultrasonic waves. Driving means for generating driving power to a vibrator, and switching of driving power from the driving means to a plurality of ultrasonic vibrators at a level where ultrasonic energy emitted from the ultrasonic probe is not locally concentrated And switching means for supplying
[0008] この場合、平面状に配置した各超音波振動子を生体に固定した状態で、超音波プ ローブ力 発する超音波エネルギーが局部的に集中しないレベルで、駆動手段から の駆動電力が超音波振動子に対して随時切替ながら与えられる。そのため、超音波 プローブから局部的に集中して超音波エネルギーが与えられることがなぐ超音波プ ローブをわざわざ動かさずに、生体の広い範囲に適切な量の超音波を照射でき、治 療時間の短縮ィ匕を図ることができる。  In this case, in a state where each of the planarly arranged ultrasonic transducers is fixed to a living body, the driving power from the driving means is excessive at a level at which the ultrasonic energy generated by the ultrasonic probe force is not concentrated locally. It is given to the sound wave vibrator while switching at any time. Therefore, it is possible to irradiate an appropriate amount of ultrasound over a wide area of the living body without having to move the ultrasound probe which can not be focused on locally and be given ultrasound energy from the ultrasound probe, and the treatment time is reduced. It can be shortened.
[0009] また本発明の超音波生体刺激装置は、前記超音波振動子を一つずつまたは複数 ずつ、或いは全数同時に振動させることができるように、前記切替手段を構成してい る。 In the ultrasonic biostimulation apparatus according to the present invention, the switching means is configured such that the ultrasonic transducers can be vibrated one by one or plural ones or all at the same time.
[0010] この場合、超音波振動子を振動させる数が少なければ、その分スポット状に位置を 変えながら超音波エネルギーを与えることができ、逆に超音波振動子を振動させる数 が多ければ、二次元エリア状に超音波エネルギーを与えることができる。そのため、 超音波プローブを生体に装着したまま、超音波振動を与える範囲を自由に可変する ことができ、刺激のパターンが多様ィ匕して、より効果的な施術効果を得ることが可能 になる。 In this case, if the number of vibrations of the ultrasonic transducer is small, ultrasonic energy can be given while changing the position in the spot shape, and if the number of vibrations of the ultrasonic transducer is large, Ultrasonic energy can be applied in a two-dimensional area. for that reason, While the ultrasonic probe is attached to the living body, the range to which the ultrasonic vibration is applied can be freely changed, and various patterns of stimulation can be obtained to obtain more effective treatment effects.
[0011] また本発明の超音波生体刺激装置は、前記切替手段による切替回数を 1秒当たり Further, in the ultrasonic biostimulation apparatus of the present invention, the number of switching times by the switching means is set per second.
100回以上としたことを特徴とする。 It is characterized in that it is made 100 times or more.
[0012] この場合、同じ超音波振動子力 長時間超音波エネルギーが出力され続けないよ うにして、局部的に同じ位置で超音波エネルギーが集中しな 、ようにすることができ る。また、人が動かす速さよりも高速で超音波振動子を掃引できるので、新たな治療 方法,治療効果も期待できる。 In this case, it is possible to prevent the ultrasonic energy from being concentrated locally at the same position, so that the ultrasonic energy does not continue to be output for a long time with the same ultrasonic transducer force. In addition, since ultrasonic transducers can be swept faster than the speed at which people move, new therapeutic methods and therapeutic effects can be expected.
[0013] また本発明の超音波生体刺激装置は、ランダムな速さと位置で、前記超音波振動 子の振動を自動的に切替えるように、前記切替手段を構成して!/、る。  Further, in the ultrasonic biostimulation apparatus of the present invention, the switching means is configured to automatically switch the vibration of the ultrasonic vibrator at random speed and position !.
[0014] この場合、特定の超音波振動子だけが長期間振動するなどの弊害が一掃され、各 超音波振動子を広範囲に且つ平均的に振動させることができる。  In this case, adverse effects such as vibration of only a specific ultrasonic transducer for a long period of time are swept away, and each ultrasonic transducer can be vibrated in a wide range and in an average manner.
[0015] また本発明の超音波生体刺激装置は、前記駆動電力の振幅を可変させる振幅可 変手段を備えている。  [0015] The ultrasonic biostimulation apparatus according to the present invention further includes an amplitude variable means for changing the amplitude of the drive power.
[0016] こうすれば、超音波振動子の駆動を切替ながら、超音波エネルギーの強さを適宜 変化させることが可能になり、刺激状態を時間と位置に応じて変えることができる。  In this way, it is possible to appropriately change the intensity of the ultrasonic energy while switching the driving of the ultrasonic transducer, and it is possible to change the stimulation state according to the time and the position.
[0017] また本発明の超音波生体刺激装置は、前記超音波振動子の振動中に、前記駆動 電力の振幅を可変制御する振幅制御手段を備えて 、る。 The ultrasonic biostimulation apparatus according to the present invention further includes an amplitude control unit that variably controls the amplitude of the drive power during the vibration of the ultrasonic transducer.
[0018] この場合、超音波振動子の振動中に、超音波エネルギーの強さをランダム若しくは 規則的に変化させることができ、超音波エネルギーによる刺激のノ リエーシヨンを持 たせることが可能になる。 In this case, the intensity of the ultrasonic energy can be changed randomly or regularly during the vibration of the ultrasonic transducer, and it becomes possible to carry the stimulation energy by ultrasonic energy.
[0019] また本発明の超音波生体刺激装置は、前記超音波振動子の振動中に、前記駆動 電力の周波数を可変制御する周波数制御手段を備えている。 The ultrasonic biostimulation apparatus of the present invention further includes frequency control means for variably controlling the frequency of the drive power while the ultrasonic transducer is vibrating.
[0020] この場合、駆動電力の周波数を可変制御することで、超音波振動の有効深度や振 動位置に変化を与えることができ、生体の同じ深さで超音波エネルギーが集中して 与えられるのを防止できる。 In this case, by variably controlling the frequency of the drive power, it is possible to change the effective depth and position of the ultrasonic vibration, and ultrasonic energy is concentrated and given at the same depth of the living body. You can prevent
[0021] また本発明の超音波生体刺激装置は、人が超音波プローブを動かしたときと同じよ うな速さと位置で、前記超音波振動子の振動を切替えるように、前記切替手段を構成 している。 Furthermore, the ultrasonic biostimulation apparatus of the present invention is the same as when a person moves the ultrasonic probe. The switching means is configured to switch the vibration of the ultrasonic transducer at a speed and a position.
[0022] この場合、実際には超音波プローブは静止して 、るものの、あた力も人が超音波プ ローブを動かしているかのように、生体に対し効果的に刺激を与えることができる。  [0022] In this case, although the ultrasound probe actually comes to rest, it is possible to effectively stimulate the living body as if a person were moving the ultrasound probe.
[0023] また本発明の超音波生体刺激装置は、前記切替手段を前記超音波プローブに組 み込んだことを特徴とする。  [0023] The ultrasonic biostimulation apparatus according to the present invention is characterized in that the switching means is incorporated in the ultrasonic probe.
[0024] この場合、配線数の多い切替手段と各超音波振動子との間の配線を、超音波プロ ーブ内に収容することができ、信頼性の高い装置を提供できる。  In this case, the wires between the switching means having a large number of wires and the ultrasonic transducers can be accommodated in the ultrasonic probe, and a highly reliable device can be provided.
[0025] また本発明の超音波生体刺激装置は、前記超音波振動子の共振周波数またはィ ンピーダンスを感知する振動子感知手段と、この振動子感知手段からの感知結果に 基づき、前記駆動電力の周波数または振幅を補正する補正手段と、をさらに備えて いる。  Further, according to the ultrasonic biostimulation apparatus of the present invention, a transducer sensing unit that senses a resonant frequency or impedance of the ultrasonic transducer, and a detection result of the transducer based on the transducer sensing unit, And D. correction means for correcting frequency or amplitude.
[0026] この場合、超音波振動子は製造的に共振周波数やインピーダンスのバラツキが避 けられないが、振動子感知手段によって超音波振動子の共振周波数またはインピー ダンスを感知し、その感知結果に応じて駆動電力の周波数または振幅を適切に補正 できるので、超音波振動子力も効率よく超音波エネルギーを発生させることができる。  In this case, although the ultrasonic transducer can not avoid variations in resonant frequency and impedance in manufacturing, the resonant frequency or impedance of the ultrasonic transducer is sensed by the transducer sensing means, and the sensed result is Accordingly, since the frequency or amplitude of the drive power can be appropriately corrected, the ultrasonic transducer force can also generate ultrasonic energy efficiently.
[0027] また本発明の超音波生体刺激装置は、前記超音波振動子が動作中のときに、一 定時間毎に前記振動子感知手段から感知結果を取り込み、前記駆動電力の周波数 または振幅を補正するように、前記補正手段を構成して!/、る。  In the ultrasonic biostimulation apparatus according to the present invention, when the ultrasonic transducer is in operation, sensing results are taken in from the transducer sensing means every fixed time, and the frequency or amplitude of the driving power is Configure the correction means to correct! /.
[0028] 超音波振動子は、動作中にその共振周波数やインピーダンスが徐々に変化するの で、一定時間毎に超音波振動子の共振周波数やインピーダンスの変動を捕え、その 変動に見合う駆動電力の周波数や振幅の補正を行なうことで、長時間の使用に際し ても効率よく超音波エネルギーを発生させることができる。  Since the resonance frequency and impedance of the ultrasonic transducer gradually change during operation, fluctuations in the resonance frequency and impedance of the ultrasonic transducer are captured at regular intervals, and the driving power that meets the fluctuation is determined. By correcting the frequency and amplitude, ultrasonic energy can be generated efficiently even when used for a long time.

Frequency correction means 36 for detecting the resonance frequency of the ultrasonic transducer 3 to correct the frequency of the oscillation output generated from the signal generation unit 22 to an optimal value, and one ultrasonic wave by the transducer switching unit 13 When the transducer 3 is driven, the impedance of the ultrasonic transducer 3 is sensed based on the detection result from the transducer detection means 26, and the amplitude of the oscillation output generated by the signal generator 22 is optimal.

For example, in FIG. 6, a section in which a specific ultrasonic transducer 3, 3 is driven (eg, a section D, I, By setting M, · · · · to be longer than the other sections, more ultrasonic energy can be given to the treatment site in the approximate center of the sheet material 2. On the contrary, for example, for ultrasonic transducers 3 and 3 which are at a site not necessary for treatment, the driving period is shorter than the other

In the case of electrical switching, the ultrasonic vibration is not effective in the drive switching time of the ultrasonic vibrators 3, 3, and -3.

超音波プローブを動かすことができない速さ(例えば 1秒間に 100回以上)で行なう のが望ましい。その理由は、駆動電力の切替速度が遅くなると、それだけ同じ超音波 振動子 3 , 3 , -3 力も長時間超音波エネルギーが出力され続けて、当該超音波ェ  It is desirable to operate at a speed at which the ultrasonic probe can not be moved (eg, 100 or more times per second). The reason is that when the switching speed of the driving power is slowed, the same ultrasonic transducers 3, 3 and -3 force are continuously output as ultrasonic energy for a long time,

In this way, while switching the drive of the ultrasonic transducers 3, 3, and 3, the intensity of the ultrasonic energy is appropriately changed.

1 2 10  1 2 10
周期 (最大値から最小値まで 5秒程度)で、駆動電力の周波数 fや振幅 Aを緩やかに 変化させることも可能である。  It is also possible to gradually change the frequency f and the amplitude A of the drive power in a cycle (about 5 seconds from the maximum value to the minimum value).
[0051] さらに、超音波エネルギーによる刺激のバリエーションを持たせるために、 CPU14 の発振出力制御手段 32からの信号制御信号を受けて、超音波振動子 3 , 3 , 〜3 Furthermore, in order to give variations of stimulation by ultrasonic energy, the ultrasonic transducers 3, 3 to 3 receive the signal control signal from the oscillation output control means 32 of the CPU 14.

The drive circuit unit 12 is configured to change the value of the amplitude A of the drive power in a sinusoidal manner. In addition, as shown in Fig. 9, the sawtooth wave is not synchronized with the entire drive pattern of the ultrasonic transducers 3, 3 and -3.

In any case, the intensity of the ultrasonic energy given to the living body can be changed gradually over a long period. Also, as shown in Fig. 8 and Fig. 9, asynchronously with the drive patterns of the ultrasonic transducers 3, 3 and -3 as a whole,

1 2 10が共振可能な周波数はある程 度の幅があるので、駆動電力の周波数 fを低くすれば、超音波振動子 3 , 3 , - --3 の  Since the frequency at which 1 2 10 can resonate has a certain degree of width, if the frequency f of the driving power is lowered, the ultrasonic transducers 3, 3,--3 can be obtained.
1 2 10 振動周波数は低くなつて、生体の深部にまで超音波エネルギーが侵入し、逆に駆動 電力の周波数 fを高くすれば、超音波振動子 3 , 3 ,ー3 の振動周波数は高くなつ  1 2 10 The vibration frequency is low, and ultrasonic energy penetrates deep into the living body. Conversely, if the frequency f of the driving power is increased, the vibration frequency of the ultrasonic transducers 3, 3, and 3 becomes high.

That is, by variably controlling the frequency f of the driving power, it is possible to change the effective depth and position of the ultrasonic vibration and to prevent the ultrasonic energy from being concentrated at the same depth of the living body. .
[0054] こうした周波数変調の一例として、例えば図 6に示す駆動パターンで、図 10に示す ように、超音波振動子 3 , 3 , -3 が駆動する各区間 B, C,…において、駆動電力 As one example of such frequency modulation, for example, in the drive pattern shown in FIG. 6, as shown in FIG. 10, in each of the sections B, C,.

In this way, from the shallow part of the living body to the deep part Stimulus can be applied while moving. Of course, if the frequency f is gradually increased in each of the sections B, C, ..., the stimulus is given by moving to the depth, partial force, and part of the living body.
[0055] また別な周波数変調の例として、図 11に示すように、各区間 B, C,…のほぼ中間 の時点で、駆動電力の周波数 Aが最も低くなるような変調を行なわせてもよい。こうす れば、各区間 B, C,…の前半において、生体の浅い部分から深い部分へと刺激が 移動し、その後は再び浅い部分へと刺激が移動して、効果的に刺激を与えることが できる。 As another example of frequency modulation, as shown in FIG. 11, even if modulation is performed such that the frequency A of drive power is the lowest at approximately the middle of each of the sections B, C,. Good. In this way, in the first half of each interval B, C, ..., the stimulus moves from the shallow part to the deep part of the living body, and then the stimulus moves to the shallow part again to effectively give a stimulus.
