ENERGY TREATMENT DEVICE

摘要

An energy treatment device includes a probe, a sheath unit, a fixed handle, a movable handle unit, a rotation axis, a jaw and a thickness-reduced portion. The thickness-reduced portion is one part of the jaw and is provided between the rotation axis and a distal end of the jaw. The thickness-reduced portion flexes in response to a reaction force when one part of the jaw receives the reaction force from a treatment target due to the opening and closing of the movable handle unit to the treatment target. The thickness-reduced portion prevents the deformation of the other parts of the jaw by flexing.

主权项

1. An energy treatment device comprising:
a probe which extends along a longitudinal axis; a sheath unit into which the probe is inserted so that a distal end portion of the probe protrudes from a distal end of the sheath; a fixed handle which is provided in a proximal end portion of the sheath unit; a movable handle unit which is openable and closable to the fixed handle; a rotation axis which is provided in a position where the sheath unit and the movable handle unit intersect with each other and which functions as a supporting point for the movable handle unit to open and close to the fixed handle; a jaw which is provided in a distal end portion of the movable handle unit and which opens and closes to the distal end portion of the probe in accordance with the opening and closing of the movable handle unit; and a thickness-reduced portion which is one part of the jaw and which is provided between the rotation axis and a distal end of the jaw, the thickness-reduced portion flexing in response to a reaction force when one part of the jaw receives the reaction force from a treatment target due to the opening and closing of the movable handle unit to the treatment target, the thickness-reduced portion preventing the deformation of the other parts of the jaw by flexing.
