The device and its manner which detect the warping condition of the medical application invasive instrument in medical behavior

摘要

(57) Abstract When it has with the ultrasonic converter and taking the position measuring element which is stuck and/or the position measurement equipment which includes the glenoid arm for specified position of the medical application invasive instrument, being interposed in the body the device which detects the warping condition of the medical application invasive instrument. Estimated position of the medical application invasive instrument, following to the measurable quantity which generates by the position measurement equipment it is calculated. The dot of echo of the medical application invasive instrument and/or the segment, is verified on the ultrasonic image. On the basis of the comparison with the position of the echo which was verified and the medical application invasive instrument (assuming that it does not warp, it detects the warping condition of the medical application invasive instrument) the position where it calculated. Furthermore, the dot of the echo which was verified in order to presume the actual form of the medical application invasive instrument/the segment is used. Furthermore, estimated position of the medical application invasive instrument and/or presumption speed is calculated, displays the calculated value in the display and shows in the user. When using the CT scanner and the MRI scanner, it is possible to utilize the device which resembles to this device.
