Abstract
An insertion assistance system includes a processor. The processor is configured to set a first position and a second position in shape information. The processor is configured to estimate a first state of a distal end of an insertion unit at the first position. The processor is configured to calculate a path through which the distal end passes. The processor is configured to determine a second state of the distal end at the second position. The processor is configured to output, to an information-reporting device, insertion assistance information required for an insertion operation for causing the distal end to reach the first position from the second position through the path and causing a state of the distal end to change from the second state to the first state.

An insertion assistance system configured to assist an insertion operation of an insertion unit when the insertion unit is inserted into a subject, the insertion unit including a lens that is disposed at a distal end of the insertion unit and is configured to acquire an optical image of the subject, the insertion assistance system comprising a processor configured to:
- set a first position and a second position in shape information indicating a three-dimensional shape of the subject,
- wherein the first position is different than a current position of the distal end and indicates a target position being a predetermined position that the distal end of the insertion unit is intended to reach, and
- wherein the second position is different from the first position;
- calculate an estimated first state for the distal end to be in at the first position on the basis of a specification of the insertion unit, the first state including a first posture of the distal end;
- calculate a path through which the distal end passes when moving from the second position to the first position and the estimated first state;
- determine a second state of the distal end at the second position, the second state including a second posture of the distal end;
- and
- output, to an information-reporting device, insertion assistance information required for the insertion operation for causing the distal end to reach the first position from the second position through the path and causing a state of the distal end to change from the second state to the first state.
An insertion assistance method causing a processor to assist an insertion operation of an insertion unit when the insertion unit is inserted into a subject, the insertion unit including a lens that is disposed at a distal end of the insertion unit and is configured to acquire an optical image of the subject, the insertion assistance method comprising:
- setting a first position and a second position in shape information indicating a three-dimensional shape of the subject,
- wherein the first position is different than a current position of the distal end and indicates a target position being a position that the distal end of the insertion unit is intended to reach, and
- wherein the second position is different from the first position;
- estimating a first state of the distal end at the first position on the basis of a specification of the insertion unit, the first state including a first posture of the distal end;
- calculating a path through which the distal end passes when moving from the second position to the first position and the estimated first state by using the processor;
- determining a second state for the distal end to be in at the second position, the second state including a second posture of the distal end;
- and
- outputting, to an information-reporting device, insertion assistance information required for the insertion operation for causing the distal end to reach the first position from the second position through the path and causing a state of the distal end to change from the second state to the first state.
A non-transitory computer-readable recording medium storing a program causing a computer to execute processing of assisting an insertion operation of an insertion unit when the insertion unit is inserted into a subject, the insertion unit including a lens that is disposed at a distal end of the insertion unit and is configured to acquire an optical image of the subject, the processing comprising:
- setting a first position and a second position in shape information indicating a three-dimensional shape of the subject,
- wherein the first position is different than a current position of the distal end and indicates a target position being a position that the distal end of the insertion unit is intended to reach, and
- wherein the second position is different from the first position;
- estimating a first state for the distal end to be in at the first position on the basis of a specification
- of the insertion unit, the first state including a first posture of the distal end;
- calculating a path through which the distal end passes when moving from the second position to the first position and the estimated first state;
- determining a second state of the distal end at the second position, the second state including a second posture of the distal end;
- and
- outputting, to an information-reporting device, insertion assistance information required for the insertion operation for causing the distal end to reach the first position from the second position through the path and causing a state of the distal end to change from the second state to the first state.
