A treatment system can include a treatment tool including an ultrasound transducer and an end effector. The system can also include an ultrasound power source configured to output a drive signal to the ultrasound transducer, and a processor configured to detect an abnormality in the end effector, and whether end effector is immersed in a liquid. The system can continue an output of the drive signal from the ultrasound power source to the ultrasound transducer when the abnormality is detected and the end effector is immersed in the liquid.

Treatment system, control device, and control method

The disclosed technology is directed to a treatment system comprises a power supply apparatus and a treatment instrument configured to communicate electrically with the power supply apparatus so as to perform a treatment on a biological tissue. The treatment instrument includes an end effector that transmits a high-frequency current delivered by a first electrical energy to the biological tissue. An electric element is configured to operate the end effector by being actuated using second electric energy. The power supply apparatus includes a processor configured to receive a stop command to cutoff the supply of the first electric energy and the second electric energy in a state in which the first electric energy and the second electric energy are supplied and determine whether or not the end effector is in contact with the biological tissue based on a parameter related to the first electric energy after receiving the stop command.

Treatment system

In an energy treatment unit and an energy treatment instrument, a jaw openable and closable relative to a probe distal portion of a probe is attached to a distal portion of an energy transmission portion. A liquid feed conduit extends between the energy transmission portion and the probe in a cavity portion, and a liquid ejected from an ejection port, that is formed at a distal end of the liquid feed conduit, flows into a jaw cavity in an inside of the jaw. A liquid outflow portion is provided on an outer surface of the jaw, and the liquid flowing into the jaw cavity flows to an outside of the jaw from the liquid outflow portion.

Energy treatment instrument

A grasping treatment device includes a first electrode portion provided at least one of in a part between a jaw and a probe electric conducting portion in opening-and-closing directions of the jaw and in the probe electric conducting portion, and a second electrode portion provided at least one of in a part between the jaw and the first electrode portion in the opening-and-closing directions of the jaw and in a jaw electric conducting portion. The grasping treatment device includes an inter-electrode distance changing unit changing an inter-electrode distance so that a second distance between the electrode portions in a second treatment mode, in which the high-frequency current alone is transmitted to the first electrode portion and second electrode portion, is smaller than a first distance between the electrode portions in a first treatment mode, in which at least an ultrasonic vibration is transmitted to a probe electric conducting portion.

Grasping treatment device

A grasping treatment device includes a first sheath section, a second sheath section including a bending cylindrical section, and a rotating transmitting portion configured to rotate to allow a grasping section and the first sheath section to rotate in one of periaxial directions of a longitudinal axis with respect to the second sheath section. The grasping treatment device includes an opening/closing transmitting portion configured to move a movable portion of the first sheath section toward a proximal direction with respect to a probe fixed portion by being pulled toward the proximal direction, and an acting force transmitting portion configured to transmit an acting force from the probe fixed portion to the bending cylindrical section, the acting force being configured to act on the probe fixed portion from the movable portion toward the proximal direction.

A grasping treatment device includes a probe including a first electrode portion in its distal portion, and a jaw configured to open or close relative to the first electrode portion and including a second electrode portion. The grasping treatment device includes a grasping force converting unit converting a grasping force so that a second grasping force between the distal portion of the probe and the jaw in a second treatment mode in which high-frequency current alone is transmitted to the first electrode portion and the second electrode portion is greater than a first grasping force between the distal portion of the probe and the jaw in a first treatment mode in which at least an ultrasonic vibration is transmitted to the distal portion of the probe.

A grasping treatment device includes a first electrode portion functioning as an electrode when a high-frequency current is transmitted thereto through a probe unit, and a second electrode portion functioning as an electrode when a high-frequency current is transmitted thereto through a sheath unit. The grasping treatment device includes an inter-electrode distance changing unit changing an inter-electrode distance so that a second distance between the electrode portions in a second treatment mode, in which the high-frequency current alone is transmitted to the two electrode portions, is smaller than a first distance between the electrode portions in a first treatment mode, in which at least an ultrasonic vibration is transmitted to a probe electric conducting portion.

A medical apparatus includes: a main body apparatus switchable to a mode for outputting ultrasound vibration, mode for outputting high-frequency current, and mode for simultaneously outputting the ultrasound vibration and the high-frequency current; a probe for performing a first treatment with a first treatment portion; a first attaching and detaching portion including a first electric armature; an insertion portion including a second treatment portion, and configured to perform a second treatment, with a living tissue held between the first treatment portion and the second treatment portion; a second attaching and detaching portion including a second electric armature; a switch control section which switches the output of the high-frequency current to a monopolar output or a bipolar output according to a connection state between the first electric armature and the second electric armature.
