Problems solved by technology

[0004] However, in the method of stopping the output when a predetermined electrical impedance is reached, as in the above-mentioned conventional example, when a blood vessel of a different thickness is used as a living tissue to be operated, for example, a closed operation (or treatment) is performed on it. , it is difficult to perform this operation simply

no. 1 approach

[0033] Such as figure 1 As shown, the high-frequency surgical device 1 according to the first embodiment of the present invention has a high-frequency power supply device 2 including a high-frequency current generating unit 31 for generating a high-frequency current for treatment (refer to figure 2 ).

[0034] The high-frequency power supply device 2 is provided with a connector socket 3 that outputs the generated high-frequency current, and a connector 5 is detachably connected to the connector socket 3, and the connector 5 is installed on a high-frequency probe as a high-frequency treatment tool. 4 to the base end of the connecting cable 4a.

[0035] This high-frequency probe 4 has: an operation part 6, which is held by the operator for operation; a sheath 7, which extends from the upper end of the operation part 6; and a treatment part 9, which passes through the front end of the sheath 7 The connection mechanism 8 is provided, and the high-frequency surgical treatment ...

no. 2 approach

[0115] Next, a second embodiment of the present invention will be described. The structure of this embodiment is with figure 1 and figure 2 The structure is the same as that of the first embodiment shown.

[0116] CPU38a of the control part 38 in this embodiment performs output control different from 1st Embodiment. In the first embodiment, closed processing is performed by an output mode.

[0117] On the other hand, in the present embodiment, the CPU 38a uses the intermittent output mode at the start of output, and when the detected impedance Za reaches the third threshold value Zf of impedance which is a control parameter for switching the output mode set in advance, In this case, control is performed to switch from the intermittent output mode to the continuous output mode. That is, in the present embodiment, the CPU 38a has a switching control unit (described later) for switching and controlling the output mode. Figure 10 Indicated by 38d) function. In addition, t...

no. 3 approach

[0145] Next, a third embodiment of the present invention will be described. The structure of this embodiment is with figure 1 and figure 2 The first embodiment shown has a similar structure. Figure 10 It shows the structure of the high-frequency power supply device 2B in the high-frequency surgical apparatus 1B of this embodiment.

[0146] The high frequency power supply unit 2B is in figure 2 The high-frequency power supply device 2 includes an impedance change amount calculation unit 38 e that calculates an impedance change amount ΔZa every predetermined time from the impedance Za detected by the impedance detection unit 37 . In addition, the CPU 38 a has a judging unit that judges whether or not the calculated impedance change amount ΔZa is greater than or equal to a preset threshold value ΔZt.

[0147] In addition, this CPU 38a has a function of a second output control unit 38f that performs output control to Reduce high-frequency current (or high-frequency energy...

Abstract

A high frequency surgery apparatus includes a high frequency current generation section that generates a high frequency current to be transmitted to a living tissue to be operated on, a high frequency probe that transmits the high frequency current to the living tissue to perform treatment with the high frequency current, a time measuring section that measures an output time of the high frequency current, an impedance detection section that detects an electric impedance of the living tissue and an output control section that performs control so as to stop the output of the high frequency current upon detecting that the output time exceeds a first threshold and detecting that the electric impedance value exceeds a second threshold.

Description

technical field [0001] The present invention relates to a high-frequency surgical device and an operating method of medical equipment for performing surgery by passing high-frequency current through living tissue. Background technique [0002] In recent years, various surgical devices have come to be used in surgical operations and the like. For example, there is currently known a technique in which high-frequency energy is applied to blood vessels for treatment. In this case, a high-frequency surgical device is used in which a high-frequency current is passed while the blood vessel is grasped with an appropriate grasping force, and the blood vessel is sealed by heat energy generated at this time. [0003] For example, in the high-frequency surgical device of Japanese Patent Application Laid-Open No. 2002-325772, the electrical impedance of the living tissue is measured while the high-frequency current is supplied to the living tissue, and the output value of the high-frequ...
