Abstract
A tubular insertion device includes a tubular insertion portion including a flexible portion in a predetermined part, bending sensors distributed and arranged in the flexible portion, and an operation support information calculating unit. The operation support information calculating unit extracts operation support information including at least first external force information regarding an external force applied to the tubular insertion portion by a combinational calculation based on detection information from the bending sensors.
Claims15
A tubular insertion device comprising:
- a tubular insertion portion including a flexible portion in a predetermined part;
- bending sensors distributed and arranged in the flexible portion;
- and
- an operation support information calculating unit configured to extract operation support information including at least first external force information regarding an external force applied to the tubular insertion portion by a combinational calculation based on detection information from the bending sensors.
A tubular insertion device comprising:
- a tubular insertion portion including a flexible portion in a predetermined part;
- bending sensors distributed and arranged in the flexible portion;
- a bending operation unit for an operator to effect a bending condition of the tubular insertion portion;
- a bending operation detection sensor configured to detect an operation amount of the bending operation unit;
- and
- an operation support information calculating unit configured to extract operation support information including at least more than one piece of external force information regarding an external force applied to the tubular insertion portion by a combinational calculation based on detection information from the bending operation detection sensor and detection information from the bending sensors, and select or simultaneously use the external force information.
A tubular insertion device comprising:
- a tubular insertion portion including a flexible portion in a predetermined part;
- a shape sensor which is disposed in the flexible portion and which detects a bending condition of the whole flexible portion;
- and
- an operation support information calculating unit configured to extract operation support information including at least external force information regarding external force applied to the tubular insertion portion by a combinational calculation based on detection information from the shape sensor in a condition in which no external force is applied to the tubular insertion portion and detection information from the shape sensor in a current condition.
