Abstract

An ultrasound treatment system in accordance with the present invention comprises an ultrasonic transducer, a handpiece, a probe, a sheath, a clamping member, an operation unit, an operating member, a suction base, and a perfusion base. The ultrasonic transducer generates ultrasonic vibrations. The handpiece has the ultrasonic transducer incorporated therein and serves as an operation unit. The probe is connected to the ultrasonic transducer, and serves as a vibration transmitting member for transmitting ultrasonic vibrations to a distal member realizing a stationary portion that is a treatment portion for treating a living tissue. The sheath serves as a protecting member for shielding the probe. The clamping member is opposed to the distal member at the distal end of the sheath, and realizes a movable portion that is another treatment portion for clamping a living tissue in cooperation with the distal member. The operation unit is manipulated for clamping a living tissue with the clamping member and distal member or freeing the living tissue therefrom.

Claims

1. An ultrasound treatment system to clamp living tissue, the system comprising:

an ultrasonic transducer for generating ultrasonic vibrations, the ultrasonic transducer having a first through hole bored therein;

a probe having a distal portion and a proximal portion, the probe having a second through hole bored therein, the probe having a distal opening at the distal portion and a proximal opening at the proximal portion which form parts of the second through hole respectively, the probe being coupled to the ultrasonic transducer to transmit the ultrasonic vibrations to the distal portion of the probe, and the first through hole communicating with the second through hole via the proximal opening when the probe is connected to the ultrasonic transducer;

a clamp provided to be movable relative to the probe to clamp the living tissue with the distal portion of the probe, the distal opening being provided in the probe spaced apart from a predetermined area on the probe, the predetermined area located to clamp the living tissue with the clamp;

a handle for operating the clamp; and

an actuating member coupled to the clamp, the actuating member actuating the clamp in response to the operation of the handle;

wherein the distal portion includes a distal end, the distal end includes an end surface, and the distal opening is located on the end surface;

wherein the distal opening of the second through hole is located away from the predetermined area, whereby suction continues as the distal opening remains open even while the living tissue is clamped by the clamp and the distal portion of the probe, and the distal opening sucks the living tissue emulsified or crushed by the treatment of the distal opening and the end surface;

wherein the predetermined area extends along a longitudinal direction of the probe and includes a side surface of the distal portion of the probe;

wherein the probe includes a first treatment portion to hold the living tissue between the side surface and the clamp; and

wherein the probe includes a second treatment portion located on the end surface which is positioned further towards a distal end of the probe than the first treatment portion and the second treatment portion includes the distal opening provided on the end surface.

2. An ultrasound treatment system according to claim 1, wherein the distal portion of the probe is of a curve shape.

3. An ultrasound treatment system according to claim 1, wherein the clamp is deformed so as to match the shape of the distal portion of the probe.

4. An ultrasound treatment system according to claim 1, wherein the probe has a notch formed at the distal portion thereof.

5. An ultrasound treatment system according to claim 4, wherein the notch is formed at the distal portion of the probe spaced apart from the predetermined area on the probe.

6. An ultrasound treatment system according to claim 1, further comprising:

a base coupled to the first through hole.

7. An ultrasound treatment system according to claim 6, further comprising:

a suction pump connected to the base.

8. An ultrasonic treatment system according to claim 1, further comprising:

a holding member which pivotally supports the clamp, the holding member being fixed at a predetermined position of the probe.

9. The ultrasound treatment system of claim 1, wherein the ultrasound appliance further comprises:

a suction base being formed at an end portion of the ultrasound appliance,

wherein the suction base communicates with the second through hole of the probe.

10. The ultrasound treatment system of claim 9, further comprising:

a suction pump to suck the freed tissue through the suction base and the second through hole of the probe; and

a suction vial storing the freed tissue sucked by the suction pump.

11. The ultrasound treatment system of claim 1, wherein the ultrasound appliance further comprises a perfusion base being formed on an outer circumference of the sheath and communicating with the inner space of the sheath.

12. The ultrasound treatment system of claim 11, further comprising a roller pump jetting liquid through the perfusion base, the inner space of the sheath, and a distal opening formed by the sheath.

13. The ultrasound treatment system of claim 1, the ultrasound appliance further comprising:

an operating rod transmitting force from the manipulator to the clamp when the manipulating of the clamp is performed; and

spacers coupling the operating rod to the probe at nodes of the ultrasonic vibrations.

14. The ultrasound treatment system of claim 13, wherein the clamp includes a curved surface contacting the distal end section of the probe when the clamp is manipulated to contact the probe.

15. The ultrasound treatment system of claim 14, wherein the clamp includes wavy portions.

16. The ultrasound treatment system of claim 13, further comprising:

a first pump pumping liquid through the inner space of the sheath and to a distal opening formed by the sheath; and

a second pump pumping the freed tissue through a through hole formed in the distal end section of the probe, and forcing the freed tissue to be placed into a vial.

17. The ultrasound treatment system as in claim 4, wherein the notch is located in an outer circumference of the distal portion of the probe and is located on a side of the probe opposed to the clamp,

whereby resection can be carried out by immobilizing the living tissue using the notch.
