Abstract

A medical system according to the present invention includes: a medical instrument provided with a treatment portion for performing treatment operations on living body tissue; a treatment portion displacement mechanism for displacing the position of the treatment portion of the medical instrument; a treatment detection portion that detects whether the treatment portion is in a treatment state or a non-treatment state; and a control portion that controls displacement of the treatment portion by controlling the treatment portion displacement mechanism according to detection results from the treatment detection portion.

Claims

1. A medical system comprising:

a medical instrument provided with a treatment portion for performing treatment operations on living body tissue;

a treatment portion displacement mechanism for displacing the position of the treatment portion of the medical instrument;

a treatment detection portion that detects whether the treatment portion is in a treatment state or a non-treatment state; and

a control portion that controls displacement of the treatment portion by controlling the treatment portion displacement mechanism according to detection results from the treatment detection portion.

2. The medical system according to claim 1, wherein

the medical instrument is a high-frequency treatment instrument that performs treatment operations using high frequency applied to the treatment portion, and the treatment detection portion detects a treatment state or a non-treatment state based on the high-frequency energization state to the treatment portion.

3. The medical system according to claim 1, wherein

the medical instrument is an opening/closing treatment instrument that performs treatment operations by the opening/closing of the treatment portion, and the treatment detection portion detects a treatment state or a non-treatment state based on the open/closed state of the treatment portion.

4. The medical system according to claim 1, wherein

the medical instrument is a rotating treatment instrument that performs treatment operations by the rotation of the treatment portion, and the treatment detection portion detects a treatment state or a non-treatment state based on the rotating state of the treatment portion.

5. The medical system according to claim 1, wherein

the treatment detection portion detects a treatment state or a non-treatment state based on the state where the treatment portion is led out from a distal end portion of the endoscope.

6. The medical system according to claim 1, wherein

based on the detection result of the treatment detection portion, the control portion drives the treatment portion displacement mechanism at a low-speed mode in which the displacement speed of the treatment portion is reduced to a predetermined speed.

7. The medical system according to claim 1, wherein

based on the detection result of the treatment detection portion, the control portion stops the treatment portion displacement mechanism so that the mode changes to a stop mode in which the advance/retreat of the treatment portion is stopped.

8. The medical system according to claim 1, wherein

based on the detection result of the treatment detection portion, the control portion drives the treatment portion displacement mechanism so that the advance/retreat displacement of the treatment portion is regulated based on a preset specified displacement value of the treatment portion.

9. The medical system according to claim 1 further comprising

a treatment storage portion that stores the treatment state or the non-treatment state of the treatment portion.

10. The medical system according to claim 1, further comprising

an operation instruction portion that outputs an instruction signal that advances/retreats the treatment portion to the control portion, wherein

the control portion drives the treatment portion displacement mechanism at a high-speed mode that increases to a predetermined speed in the retreating direction of the treatment portion based on detection results of the treatment detection portion and predetermined operations of the operation instruction portion.

11. The medical system according to claim 1, wherein

the medical instrument is an endoscopic treatment instrument that is inserted into a channel disposed in an insertion portion of an endoscope, and

the treatment instrument displacement mechanism is an advance/retreat apparatus that advances/retreats the treatment portion with respect to the endoscope.

12. The medical system according to claim 1, wherein

the medical instrument is an endoscopic treatment instrument that is inserted into a channel disposed in an insertion portion of an endoscope, and

the displacement mechanism is a bending portion disposed to the insertion portion of the endoscope.

13. The medical system according to claim 1, further comprising

a treatment portion operation apparatus that drives the treatment portion.

14. The medical system according to claim 10, wherein

the treatment detection portion detects a treatment state or a non-treatment state of the treatment portion based on a light modulation function executed by the endoscope.

15. The medical system according to claim 10, wherein

the treatment detection portion is an optical sensor provided on a distal end portion of the endoscope, and which detects a treatment state or a non-treatment state based on the state where the treatment portion is introduced or led out from the distal end portion.

16. The medical system according to claim 15, wherein

the treatment portion has a reflector that reflects the optical sensor, and a reflecting surface set to a predetermined curvature is formed on the reflector.
