摘要： An end effector grasps a treatment target between a pair of gasping pieces, and an energy output source outputs electric energy so that treatment energy is applied to the grasped treatment target. A processor switches a driving state of an actuator based on a fact that a state of the treatment target has become a predetermined state when the electric energy is output from the energy output source. As the result, a state of the end effector is switched from a first grasping state to a second grasping state, a grasping force and a grasping pressure between the first grasping piece and the second grasping piece in the second grasping state being different from those in the first grasping state.

摘要： A medical apparatus includes a treatment device configured to be capable of treating a subject by applying energy to the subject, an optical fiber including a light emitting face for emitting light into the subject, the optical fiber being connected to the treatment device, and a shield portion that is disposed in front of the light emitting face of the optical fiber, the shield portion being configured to expose the light emitting face when the treatment device does not perform a treatment operation and to shield the light emitting face when the treatment device performs the treatment operation.
