Abstract

A surgical operating apparatus includes a probe for outputting energy for performing therapeutic treatment of a living body, a jaw which is openable/closable relative to the probe, and an output mode switching section which selectively switches, in accordance with an open/closed state of the jaw, an output of the surgical operating apparatus between a bipolar mode in which the probe and the jaw are used as high-frequency electrodes, and a probe-only output mode in which the energy is output from only the probe.

Claims

1. A surgical operating apparatus comprising:

a probe for outputting energy for performing therapeutic treatment of a living body;

a jaw which is openable/closable relative to the probe; and

an output mode switching section which selectively switches, in accordance with an open/closed state of the jaw, an output of the surgical operating apparatus between a bipolar mode in which the probe and the jaw are used as high-frequency electrodes, and a probe-only output mode in which the energy is output from only the probe.

2. The surgical operating apparatus according to claim 1, wherein the surgical operating apparatus further includes an operation section for opening/closing the jaw, and

the output mode switching section switches the output of the surgical operating apparatus to the bipolar mode in a case where a living body tissue is held between the probe and the jaw in accordance with an operation of the operation section and the jaw is substantially closed relative to the probe, and switches the output of the surgical operating apparatus to the probe-only output mode in a case where the jaw is in an open state in which the jaw is not substantially closed relative to the probe.

3. The surgical operating apparatus according to claim 1, wherein in the probe-only output mode, only a high-frequency current is output as the energy from the probe.

4. The surgical operating apparatus according to claim 1, wherein the surgical operating apparatus further includes an ultrasonic output section which supplies an ultrasonic output to the probe.

5. The surgical operating apparatus according to claim 4, wherein in the probe-only output mode, only ultrasonic from the ultrasonic output section is output as the energy from the probe.

6. The surgical operating apparatus according to claim 4, wherein in the probe-only output mode, a high-frequency wave and ultrasonic are simultaneously output as the energy from the probe.

7. The surgical operating apparatus according to claim 4, wherein in the bipolar mode, ultrasonic is also output as the energy from the probe at the same time.

8. A surgical operating apparatus comprising:

a probe for outputting energy for performing therapeutic treatment of a living body;

a jaw which is openable/closable relative to the probe;

an operation section for opening/closing the jaw; and

an output mode switching section which selectively switches an output mode of the probe between a probe-only output mode in which the energy is output from only the probe, and a bipolar mode in which the probe and the jaw are used as high-frequency electrodes,

wherein the output mode switching section includes a contact-point switching section which opens/closes a contact point that switches on/off an electrical conduction state of a high-frequency current to the jaw in accordance with an operation of a movable member which moves in accordance with an operation of the operation section.

9. The surgical operating apparatus according to claim 8, wherein the contact-point switching section closes the contact point in accordance with the operation of the movable member at a time when the operation section moves the jaw in a direction of closing, thereby effecting switching to a state in which the high-frequency current to the jaw is rendered conductive, and opens the contact point in accordance with the operation of the movable member at a time when the operation section moves the jaw in a direction of opening, thereby effecting switching to a state in which the high-frequency current to the jaw is rendered non-conductive.

10. The surgical operating apparatus according to claim 8, wherein the movable member includes an operation force transmission member which is advanced/retreated in an axial direction of the probe in accordance with the operation of the operation section and transmits an operation force of the operation section to the jaw, and

the contact-point switching section opens/closes the contact point in accordance with an advancing/retreating operation of the operation force transmission member.

11. The surgical operating apparatus according to claim 10, wherein the contact-point switching section closes the contact point in accordance with the advancing/retreating operation of the operation force transmission member at the time when the operation section moves the jaw in a direction of closing, thereby effecting switching to a state in which the high-frequency current to the jaw is rendered conductive, and opens the contact point in accordance with the advancing/retreating operation of the operation force transmission member at the time when the operation section moves the jaw in a direction of opening, thereby effecting switching to a state in which the high-frequency current to the jaw is rendered non-conductive.

12. The surgical operating apparatus according to claim 8, wherein the operation section includes a stationary handle and a movable handle which moves in a direction toward/away from the stationary handle,

the movable member is composed of the movable handle, and

the contact-point switching section which closes the contact point in accordance with an operation of the movable handle at a time when the operation section moves the jaw in a direction of closing, thereby effecting switching to a state in which the high-frequency current to the jaw is rendered conductive, and opens the contact point in accordance with the operation of the movable handle at a time when the operation section moves the jaw in a direction of opening, thereby effecting switching to a state in which the high-frequency current to the jaw is rendered non-conductive.

13. The surgical operating apparatus according to claim 8, wherein in the probe-only output mode, only a high-frequency current is output as the energy from the probe.

14. The surgical operating apparatus according to claim 8, wherein the surgical operating apparatus further includes an ultrasonic output section which supplies an ultrasonic output to the probe.

15. The surgical operating apparatus according to claim 14, wherein in the probe-only output mode, only ultrasonic from the ultrasonic output section is output as the energy from the probe.

16. The surgical operating apparatus according to claim 14, wherein in the probe-only output mode, a high-frequency wave and ultrasonic are simultaneously output as the energy from the probe.

17. The surgical operating apparatus according to claim 14, wherein in the bipolar mode, ultrasonic is also output as the energy from the probe at the same time.

18. A surgical operating apparatus comprising:

a probe for outputting energy for performing therapeutic treatment of a living body;

a jaw which is openable/closable relative to the probe; and

output mode switching means for effecting switching between a bipolar mode in which the probe and the jaw are used as electrodes, and a probe-only output mode in which energy is output from only the probe,

wherein the output mode switching means operates in interlock with an opening/closing operation of the jaw, effects switching to the bipolar mode at a time of a closing operation of the jaw, and effects switching to the probe-only output mode at a time of a openable operation of the jaw.
