Abstract

A medical manipulator system of the present invention includes: a medical instrument having a shape insertable into an elongated tube passage and in which one or a plurality of flexion portions are provided; a flexing actuator for supplying a driving force to flex the flexion portion; an actuator control section for controlling the flexing actuator; a detecting section provided inside the tube passage to output a detection signal when detecting that the flexion portion passes therethrough; and a computing section for performing computation to match a flexed state of the flexion portion passing through the detecting section to an operating state of an operation portion operable to flex the flexion portion based on an operation amount of the flexing actuator detected when the detection signal is inputted.

Claims

1. A medical manipulator system comprising:

a medical instrument having a shape insertable into an elongated tube passage and in which one or a plurality of flexion portions are provided;

a flexing actuator for supplying a driving force to flex the flexion portion;

an actuator control section for controlling the flexing actuator;

a detecting section provided inside the tube passage to output a detection signal when detecting that the flexion portion passes therethrough; and

a computing section for detecting an operation amount of the flexing actuator when the detection signal is inputted, and performing computation to match a flexed state of the flexion portion passing through the detecting section to an operating state of an operation portion operable to flex the flexion portion based on the operation amount.

5. The medical manipulator system according to claim 1,

wherein the actuator is a motor.

2. A medical manipulator system comprising:

a medical instrument having a shape insertable into an elongated tube passage and in which one or a plurality of flexion portions are provided;

a flexing actuator for supplying a driving force to flex the flexion portion;

an inserting actuator for supplying a driving force to insert the medical instrument into the tube passage;

an actuator control section for controlling the flexing actuator and the inserting actuator; and

a computing section for detecting an operation amount of the flexing actuator when the medical instrument is inserted a predetermined amount into the tube passage by the inserting actuator, and performing computation to match a flexed state of the flexion portion passing through the detecting section to an operating state of an operation portion operable to flex the flexion portion based on the operation amount.

3. A medical manipulator system comprising:

a medical instrument having a shape insertable into an elongated tube passage and in which one or a plurality of flexion portions are provided;

a flexing actuator connected to the flexion portion by a wire to supply a driving force to flex the flexion portion via the wire;

a detecting section provided inside the tube passage to output a detection signal when detecting that the flexion portion passes therethrough;

an actuator control section for performing control to drive the flexing actuator until slack in the wire is removed when the detection signal is inputted; and

a computing section for detecting a drive amount of the flexing actuator in accordance with control of the actuator control section, and performing computation to match a flexed state of the flexion portion passing through the detecting section to an operating state of an operation portion operable to flex the flexion portion based on the drive amount.

4. A medical manipulator system comprising:

a medical instrument having a shape insertable into an elongated tube passage and in which one or a plurality of flexion portions are provided;

an inserting actuator for supplying a driving force to insert the medical instrument into the tube passage;

a flexing actuator connected to the flexion portion by a wire to supply a driving force to flex the flexion portion via the wire;

an actuator control section for controlling the inserting actuator and performing control to drive the flexing actuator until slack in the wire is removed when the medical instrument is inserted a predetermined amount into the tube passage by the inserting actuator; and

a computing section for detecting an operation amount of the flexing actuator in accordance with control of the actuator control section when the medical instrument is inserted the predetermined amount into the tube passage by the inserting actuator, and performing computation to match a flexed state of the flexion portion passing through the detecting section to an operating state of an operation portion operable to flex the flexion portion based on the operation amount.

6. A medical manipulator system comprising:

a tubular medical instrument having a diameter insertable into a tubular body cavity, and a flexible portion capable of being flexed and having flexibility;

a tube passage extending eccentrically relative to a central axis of the medical instrument;

a wire inserted into the tube passage in a forward/backward movable manner;

a moved portion moved in accordance with forward/backward movement of the wire to perform observation or treatment;

a first detecting section for detecting a relative moving amount of the wire with respect to the tube passage, the moving amount being generated in accordance with flexion of the flexible portion;

a second detecting section for detecting that the medical instrument is inserted into the tubular body cavity; and

a control section capable of controlling the forward/backward movement of the wire in a direction in which the moving amount is reduced based on detection results of the first and second detecting sections.
