An ultrasonic lithotripter comprising a first transmission probe which has a hollow portion in the form of a through hole and transmits ultrasonic vibration and a superfine second transmission probe which can be passed through the hollow portion of the first transmission probe. An object of manipulation is held by means of the second transmission probe as it is manipulated by means of the first transmission probe.

Calculus manipulation apparatus

An endoscopic lithotripsy probe apparatus includes a probe, ultrasonic-vibration source, mechanical shock generation source, and switch-mechanism. The ultrasonic-vibration source is detachably attached to the probe to transmit an ultrasonic-vibration to the probe in a state in which the proximal end of the probe is connected to the ultrasonic-vibration source. The mechanical shock generation source, which is disposed on the side of the proximal end of the probe, applies a force to the ultrasonic-vibration source in a state in which the ultrasonic-vibration source is detached from the proximal end of the probe, and allows the ultrasonic-vibration source to collide with the proximal end of the probe so that a mechanical shock is applied to the probe. The switch-mechanism switches a state in which the ultrasonic-vibration from the ultrasonic-vibration source is transmitted to the probe and a state in which the mechanical shock from the mechanical shock generation source is transmitted.

When vital tissue is gripped between the jaws, the effective electrode surface of the second electrode portion, which is to be brought into contact with the vital tissue, is smaller than that of the second electrode portion.

High-frequency treatment tool

A high frequency treatment apparatus of the present invention comprises a high frequency generation section for supplying high frequency power, a control section, which is connected to the high frequency generation section, and which controls output of the high frequency generation section, having a first control mode in which the maximal output value of high frequency power supplied from the high frequency generation section is confined to be equal to or less than a first predetermined value and a second control mode in which the maximal output value of high frequency power supplied from the high frequency generation section is confined to be equal to or less than a second predetermined value which is less than the first predetermined value, a treatment tool, which is connected to the high frequency generation section, and which performs a treatment of a diseased part by supplying high frequency power from the high frequency generation section controlled by the control section to the diseased part, and a control mode setting section, which is connected to the control section, for selecting one of the first and second control modes.

High frequency treatment apparatus

An electric medical apparatus according to the present invention performs an incising treatment automatically after the coagulating treatment has been performed without a necessity for an operator to perform another operation between the two treatment operations when the incising treatment performs after a coagulating treatment. The electric medical apparatus comprises a CPU, a waveform generating circuit, an amplifier and an output control unit to supply an output for performing the coagulating treatment to a treatment device and an output for performing the incising treatment to the treatment device. The impedance of a living tissue with which the treatment device is brought into contact is measured and calculated by a voltage sensor, a current sensor and an impedance calculating portion. In accordance with a result of the calculation performed by the impedance calculating portion, an output from an electric knife body is, by the CPU, switched to the output for the incising treatment after the coagulating treatment has been performed.

Electric medical apparatus

A high-frequency treatment tool includes an insertion portion which can be inserted into a body, a pair of gripping portions arranged at a distal end portion of the insertion portion and having gripping surfaces for gripping vital tissue, a driving mechanism for opening/closing the gripping portions between closing positions where the gripping portions abut against each other and open positions where the gripping portions are separated from each other, electrode portions formed on the gripping surfaces of the gripping portions, to which a high-frequency current is flowed to coagulate/incise the vital tissue gripped by the gripping portions, and a short circuit prevention portion for preventing a short circuit between the electrode portions of the gripping portions when the gripping portions are placed at least at the closing positions.

A high-frequency treatment apparatus has a high-frequency treatment tool having, at its distal end portion, a treatment portion for coagulating or incising tissue. A high-frequency output power supply unit is electrically connected to the high-frequency treatment tool to selectively generate a high-frequency coagulation output for coagulating tissue and a high-frequency incision output for incising the tissue on the basis of a signal generated upon manipulating a manipulation portion. The manipulation portion has a control mechanism for causing the high-frequency treatment tool to incise tissue after coagulation of the tissue by the high-frequency treatment tool is completed.
