Ultrasonic treatment device with mist suctioning structure
First Claim
1. An ultrasonic treatment device comprising:
- a handpiece having an ultrasonic transducer;
a probe having a base end connected to the ultrasonic transducer;
a tubular inner sheath covering the probe;
an outer sheath having a base end and covering the inner sheath with a predetermined space left between both the sheaths, the space functioning as a suction path for mist;
a base-end sealing member made of an elastic material, disposed on the base end of the outer sheath and engaged detachably with the inner sheath to seal a gap formed with the inner sheath; and
a suction member disposed on a base-end side of the outer sheath, formed to communicate with the suction path formed between both the outer and inner sheaths, and configured to suck in the mist through the suction path.

Abstract
An ultrasonic treatment device comprises a handpiece having an ultrasonic transducer and a long axial probe whose base end is connected with the transducer. The device further comprises a tubular inner sheath covering the probe and an outer sheath covering the inner sheath with a predetermined annular space left therebetween. The space between the sheaths is used as a suction path for mist. For the suction, the device further comprises a base-end sealing member made of an elastic material, disposed on a base-end side of the outer sheath and engaged detachably with the inner sheath to seal a gap formed with the inner sheath. A suction unit is disposed on the base-end side of the outer sheath. The suction unit sucks in mist to be generated when ultrasonic treatment is performed, through the suction path, and discharged outside.

11. An ultrasonic treatment device comprising:
-
a handpiece having an ultrasonic transducer;
a probe having a base end connected to the ultrasonic transducer;
a tubular inner sheath covering the probe;
an outer sheath having a base end and covering the inner sheath with a predetermined space left between both the sheaths, the space functioning as a first suction path for mist;
a base-end sealing member made of an elastic material, disposed on a base-end side of the outer sheath and engaged detachably with the inner sheath to seal a gap formed with the inner sheath;
a suction member disposed on a base-end side of the outer sheath, formed to communicate with the first suction path formed between both the outer and inner sheaths; and
a distal-end sealing member made of an elastic material, disposed on a distal end of the outer sheath, and engaged detachably with the inner sheath to seal a gap formed with the inner sheath, wherein a hole is formed through the inner sheath at a predetermined position of the inner sheath, the predetermined position being nearer to the base end of the inner sheath than a touched position of the distal-end sealing member to the inner sheath, such that the hole connects a further gap between the distal end of the probe and the inner sheath and the first suction path, the further gap functioning as a second suction path for the mist, the probe has an elastic support member formed to provide an outer diameter and located at a position of the probe, the position corresponding to a node of ultrasonic vibration to be transmitted from the ultrasonic transducer via the probe, the inner sheath has an inner diameter smaller than the outer diameter of the elastic support member, and the hole of the inner sheath is located between the elastic support member and the distal-end sealing member. - View Dependent Claims (13)

14. An ultrasonic treatment device comprising:
-
a handpiece having an ultrasonic transducer;
a probe connected to the ultrasonic transducer;
a first sheath covering an outer surface of the probe;
a second sheath covering an outer surface of the first sheath;
a first suction path formed between the first and second sheaths; and
a suction mouthpiece mounted on an base end of the probe and formed to communicate with the first suction path, the base end being opposite to a distal end of the probe, the distal end being coupled with a treatment piece with ultrasonic vibration to be transmitted from the ultrasonic transducer. - View Dependent Claims (15, 16)
