在に取付けられている。[Prior Art] As one of the conventional ultrasonic therapy devices, there is a special table 63-50.
There is one disclosed in Japanese Patent No. 1845. In this case, the transducer is bent at an intermediate portion between the vibration node and the antinode, and the outer diameter of the transducer changes at the antinode of the bent portion. In addition, a hollow cylindrical body is coated around the transducer to form an irrigation channel,
Sleeve means is detachably attached to the tip of the hollow cylindrical body so as to surround the outer circumference of the tip connected to the tip of the transducer.

The irrigation tube passes through the outside of the bellows cover and is inserted into a tube hole provided in the tip cover.

No. 4,526,571 is one in which a transducer is bent by bending ≧ 0.7λ (λ: wavelength), and a tip is connected to the tip thereof, and an arc shape along the bending R of the transducer is provided outside thereof. A curved hollow cylindrical body is provided, and sleeve means is connected to the tip thereof.

安全かつ確実な手術が行なえないものであった。[Problems to be Solved by the Invention] However, in the above-mentioned Japanese Patent Publication No. 63-501845, since the step portion is formed at the connecting portion between the transducer and the chip, a hollow cylindrical shape provided outside the transducer is provided. The body is inevitably thicker than the sleeve means on the outside of the tip. A curved or bent ultrasound treatment device is most effective when treating a lesion such as a tumor in the deep brain where the symmetry site of surgery is deep inside the body and the surgical field is narrow under a surgical microscope. If the thickness is too large, it will obstruct the operative field and also obstruct the field of view of the microscope.
The operation was not safe and reliable.

り、清掃しにくいという問題もある。Also in Japanese Utility Model Laid-Open No. 63-184006, the bellows cover is thicker than the chip cover, and has the same problem as described above. Moreover, since the irrigation tube is exposed to the outside of the bellows cover, the irrigation tube also obstructs the operative field and the field of view of the microscope.
There was also a risk of damaging normal tissue with the exposed irrigation tube. Further, there are problems that the unevenness on the outer periphery of the bellows damages the tissue, and that the tissue pieces, blood, etc. accumulate in the recesses, making cleaning difficult.

勝手が極めて悪いものになってしまう。The thing of USP4526261 has the same problem as above, and since it is bent with a large bend R of R ≧ 0.7λ, the bending angle between the handpiece and the tip cannot be increased, so that ultrasonic treatment is required during use. The device must be used in a nearly vertical position, which greatly obstructs the operative field and the field of view of the microscope. In order to increase the bending angle, it is necessary to lengthen the probe, which makes it extremely unusable.

An object of the present invention is to provide an ultrasonic treatment device that can be performed.

It has a length of (λ: wavelength), has a vibration antinode at the tip of the horn 6 and a rear end of the handpiece 9, and has a vibration node near the flange 13 of the horn 6. This vibration is transmitted to the probe 11, and the probe 11 vibrates to transmit the vibration to the tip of the tool 21 to emulsify, incise, excise, or crush the tissue, stones, hematoma, etc. contacting the tip of the tool 21. The probe 11 uses the bending portion 18 as an antinode of vibration, and has one vibration node before and after the vibration, and the tool 21
Has a length of λ as a whole with the tip of the as an abdomen of vibration. The ultrasonic therapy device constitutes a resonance system as a whole.

てもよい。It is effective to provide the protrusions 31 and 32 in the vicinity of the vibration node in order to reduce the vibration loss due to contact with the probe 11. Although the bending portion 18 is located at a position λ / 2 from the vibration abdomen here, that is, from the tip of the horn 6, it is not limited to the abdomen, and the vibration node, that is, from the tip of the horn 6 to λ. / 4 or 3λ / 4 part,
Further, it may be located at an intermediate portion between the abdominal portion and the node portion of the vibration, that is, a portion of λ / 8, 3λ / 8, 5λ / 8, 7λ / 8 from the tip of the horn 6. Furthermore, the length of the vibration generator 8 is λ /
The number is not limited to 2, and may be nλ / 2 (n: integer),

Since the connection cover 27 of the sheath 12 that covers the curved portion 18 of No. 1 can be curved along the curve of the curved portion 18 and the outer peripheral surface of the connection cover 27 is formed smoothly, the outer peripheral surface of the sheath 12 is smoothly continuous. The curved portion 18 and the front and rear outer diameters thereof can be reduced.
Therefore, the deep part of the living body can be safely and reliably treated without obstructing the surgical field or the field of view of the microscope. Moreover, since the connecting cover 27 is curved along the curve of the bending portion 18, the connecting cover 27 is pulled in the axial direction and extends in the same direction, and also contracts in the radial direction. As a result, the outer diameter of the connecting cover 27 is reduced. Becomes smaller.

対しても適用可能となる。In addition, since the connection cover 27 is deformed along the curve even for an arbitrary curve angle θ, various kinds of curve angles θ can be obtained with one sheath.
It is applicable to a probe having a sheath, the versatility of the sheath 12 is improved, and it is economical. Moreover, it can be applied to a bent probe and a straight probe that is not curved or bent.

Further, the projection 3 is formed on the inner wall of the sheath 12.
Since 1, 32 are provided, the eccentricity between the sheath 12 and the probe 11, that is, the water supply passage 30 can be surely ensured, and the perfusate can surely flow. Therefore, the operation can always be performed in a stable state.

なるものである。[Effects of the Invention] As described above, according to the ultrasonic treatment apparatus of the present invention, the ultrasonic generator is detachably attached to the tip of the vibration generator, and at least the tip is curved or bent with respect to the long axis of the vibration generator. It is possible to reduce the outer diameter of the above-mentioned curved portion or bent portion, and the front and rear portions of the sheath covered on the outer periphery of the tapered probe to be connected, and to safely and reliably perform the operation without disturbing the operative field and the visual field of the microscope. Deep treatment can be performed. In addition, a single sheath can be used for a straight probe to a plurality of probes having arbitrary bending or bending angles, which simplifies the system, makes it easy to use, and is economical. Furthermore, there is no risk of damaging the tissue on the outer peripheral surface of the sheath, and dirt such as blood and body fluid is unlikely to adhere to the outer peripheral surface of the sheath, so that the sheath is always clean and easy to clean.
