Abstract
A treatment device includes: a probe including a treatment portion that performs treatment to a treatment target portion by transmission of ultrasonic vibration; a first sheath having a first edge and enclosing a periphery of the probe; a second sheath having a second edge and enclosing a periphery of the first sheath; a suction path including a suction opening between the first edge and the second edge and provided between the first sheath and the second sheath; and a connection part communicating with the suction path and connected to a suction source.

1-11. (canceled)
A treatment device comprising:
- a probe including an axial portion that defines a longitudinal axis in which ultrasonic vibration is transmitted, and a cutting blade provided on a distal side of the axial portion and projecting in a direction crossing the longitudinal axis;
- a first sheath enclosing an outer peripheral surface of the axial portion in the probe;
- a second sheath being arranged eccentric from the longitudinal axis of the probe toward a side where the cutting blade is provided, and enclosing a periphery of the first sheath, and the second sheath forming a suction path including, between a periphery of the first sheath and the second sheath, a wide portion corresponding to a side where the cutting blade is provided and a narrow portion corresponding to a side opposite to the side where the cutting blade is provided;
- a connection part communicating with the suction path and connected to a suction source,
- wherein when a height of the cutting blade in a direction crossing the longitudinal axis direction is represented as H1, a height of the wide portion in the direction crossing the longitudinal axis is represented as H2, and a height of the narrow part in the direction crossing the longitudinal axis is represented as H0, a relationship of H2>H1>H0 is satisfied.
A treatment device comprising:
- a probe including an axial portion that defines a longitudinal axis in which ultrasonic vibration is transmitted, and a cutting blade provided on a distal side of the axial portion and projecting in a direction crossing the longitudinal axis;
- a first sheath having a first edge and enclosing an outer peripheral surface of the axial portion in the probe, and being fixed in the longitudinal axis direction with respect to the probe;
- a second sheath having a second edge and enclosing a periphery of the first sheath, and forming a suction path between the periphery of the first sheath and the second sheath and being fixed in the longitudinal axis direction with respect to the probe;
- and
- a connection part communicating with the suction path and connected to a suction source,
- wherein when a height of the cutting blade in the direction crossing the longitudinal axis direction is represented as H1, and a height of the suction path in the direction crossing the longitudinal axis direction is represented as H2, the suction path has a portion where a relationship of H2>H1 is satisfied,
- the suction path has a suction opening between the first edge and the second edge, and the suction opening is provided in a vicinity of the cutting blade.
