Abstract

An endoscopic surgery device that can easily acquire an image desired by a surgeon, and that has high operability. The endoscopic surgery device includes: an outer tube body that penetrates through a body wall to be inserted into a body cavity; an endoscope insertion path that is provided inside the outer tube body; a treatment tool insertion path that is provided inside the outer tube body; an endoscope drive unit that has a non-operating area where an endoscope insertion part inserted into the endoscope insertion path is not moved, and an operating area where the endoscope insertion part is moved; a position sensor that detects a movement amount of treatment tool insertion part with respect to the outer tube body; and a control unit that controls the endoscope drive unit in accordance with the movement amount of the treatment tool insertion part, detected by the position sensor.

Claims

1. An endoscopic surgery device comprising:

a guide member configured to penetrate through a body wall to be inserted into a body cavity;

an endoscope insertion path which is provided inside the guide member, and into which an endoscope configured to observe an inside of the body cavity is insertable in a back-and-forth movable manner;

a treatment tool insertion path which is provided inside the guide member, and into which a treatment tool configured to inspect or treat a diseased part in the body cavity is insertable in a back-and-forth movable manner;

an endoscope drive unit including a non-operating area where the endoscope inserted into the endoscope insertion path is not moved back and forth, and an operating area which is an area other than the non-operating area, and in which the endoscope is moved back and forth;

a detection unit configured to detect a movement amount of the treatment tool with respect to the guide member when the treatment tool inserted into the treatment tool insertion path moves back and forth; and

a control unit configured to control the endoscope drive unit in accordance with the movement amount of the treatment tool detected by the detection unit.

2. The endoscopic surgery device according to claim 1, wherein

the endoscope drive unit comprises a driving member configured to move back and forth in the endoscope insertion path to allow the endoscope to move back and forth in interlock with the driving member, and

the driving member is provided with an allowance part corresponding to the non-operating area, beyond which the endoscope starts moving back and forth in interlock with the driving member.

3. The endoscopic surgery device according to claim 1, wherein

the detection unit includes:

a calculation unit configured to calculate the movement amount of the treatment tool in an observation image; and

a conversion unit configured to convert the movement amount of the treatment tool in the observation image calculated by the calculation unit into an actual movement amount.

4. The endoscopic surgery device according to claim 1, wherein the control unit controls the endoscope drive unit so as to allow the endoscope to move back and forth in proportion to the movement amount of the treatment tool.
