Title:
SURGICAL INSTRUMENT POSITION ATTITUDE MEASURING APPARATUS
Document Type and Number:
Japanese Patent JP2016002445
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a surgical instrument position attitude measuring apparatus that is used to perform high-precision three-dimensional position attitude measurement for a surgical instrument by using an inertial sensor and a displacement measuring sensor.SOLUTION: An inertial sensor 5 and a displacement measuring sensor 6 are built into a hollow tube 3 for use in endoscopic surgical operation. A position attitude of a surgical instrument 2 is calculated by being converted to a coordinate system serving as a standard of the surgical instrument 2 inserted through the hollow tube by using constraint conditions at an insertion point 4 into the body.
