Problems solved by technology

[0007] However, when a treatment is performed using high-frequency energy and other energy at the same time, even if a disconnection occurs, it is in a state where treatment can be performed by the other energy, so it is difficult to quickly grasp the occurrence of a disconnection.
In addition, in this case, compared with the state in which two types of energy are used for treatment at the same time, the function is degraded, so compared with the state of simultaneous use, appropriate treatment can be completed in a short time. In this case, only Disposal is performed in a state where the energy and disposal capacity are reduced, so the disposal may be time-consuming

no. 1 approach

[0031] Such as figure 1 As shown, the surgical operation system 1 of the first embodiment of the present invention is composed of a power supply device 2 and a high-frequency and ultrasonic treatment instrument (hereinafter referred to as the treatment instrument) 3 as a surgical treatment instrument. The power supply device 2 can simultaneously output A high-frequency signal as a first signal for providing high-frequency energy to biological tissue, a second signal for providing energy different from high-frequency energy to biological tissue, the high-frequency and ultrasonic treatment instrument as a surgical treatment instrument 3. It is detachably connected to the power supply unit 2, and the living tissue to be treated, for example, the blood vessel 4 is treated with high-frequency energy and ultrasonic energy. In addition, in this embodiment, since ultrasonic energy is used as energy other than high-frequency energy, for example, the second signal becomes an ultrasonic ...

no. 2 approach

[0160] Next, a second embodiment of the present invention will be described. Figure 8 A surgical system 1B of the second embodiment is shown. The surgical system 1B has a power supply device 2B and a treatment tool 3B including a connector 6 detachably connected to the power supply device 2B.

[0161] The treatment instrument 3B has, for example, an information storage unit 61 in the connector 6 in the treatment instrument 3 of the first embodiment, and the information storage unit 61 stores the height of the ultrasonic transducer unit 8 including the cable 7 measured at the time of shipment. information on the capacitance value Cu of the frequency signal lines 8a and 8b. In addition, the capacitance value Cu is measured (calculated) using, for example, a capacitance measuring device capable of measuring the capacitance value with high precision.

[0162] This information storage unit 61 is connected to a contact 62 provided on the connector 6 so that stored information can...

no. 3 approach

[0171] Next, a third embodiment of the present invention will be described. The present embodiment is, for example, the surgical system 1 capable of detecting disconnection with high precision in the case of the treatment instrument 3 of the first embodiment. For example, the hardware configuration is the same as that of the first embodiment, and the procedure for detecting occurrence of disconnection is different.

[0172] Figure 11 The operation including the process of determining whether or not there is a disconnection in this embodiment is shown.

[0173] In the initial step S31 , the operator connects the ultrasonic transducer unit 8 actually used in the operation to the power supply device 2 and turns on the power switch 50 of the power supply device 2 . In the next step S32, the operator performs a process of confirming that the ultrasonic transducer unit 8 is not disconnected, but is conducting.

[0174] For example, when confirming continuity with the ultrasonic ...

Abstract

In the present invention, a surgical system has: a power supply device that is provided with first signal and second signal generation units that respectively generate a first signal and a second signal as high-frequency signals; a surgical treatment tool which is provided with a converter that converts a supplied second signal to other energy, and a pair of electrodes; a cable which connects the surgical treatment tool to the power supply device; a measurement unit which measures a high-frequency voltage and a high-frequency current with respect to biological tissue to which a high-frequency signal is supplied via the cable and the surgical treatment tool; a calculation unit which calculates capacitive values of the cable and the surgical treatment tool on the basis of the measured high-frequency voltage and high-frequency current; an assessment unit which assesses whether or not the calculated capacitive values are smaller than a threshold for detecting disconnection; and a control unit which performs output control of the high-frequency signals and the like on the basis of the assessment results by the assessment unit.

Description

technical field [0001] The present invention relates to a surgical system for performing surgical procedures using high frequency energy and other energies. Background technique [0002] Conventionally, treatments such as excision and incision by supplying high-frequency energy to living tissue to be treated have been widely performed. [0003] In recent years, in addition to high-frequency energy, ultrasonic energy has been supplied to living tissue to be treated to perform treatments such as excision and incision. [0004] For example, the conventional example of US Patent Publication No. 2008 / 0132887 discloses a surgical device that uses high-frequency current and ultrasonic vibration to hold a living tissue with a strong holding force, and then coagulates and incises it. [0005] In this way, in the case of using other energy such as high-frequency energy and ultrasonic energy for treatment, when the high-frequency signal line that transmits the high-frequency signal is...
