Estimating the term…
The invention relates to a surgical instrument with an instrument handle, an instrument shank connected to the instrument handle, an instrument tip with a work point, which instrument tip is connected to the instrument shank, and a first locator arranged on the instrument handle or the instrument shank. During a use of the surgical instrument, the instrument shank can be deflected, e.g. on account of transverse forces, at least between the first locator and the work point. A second locator is arranged at a distance from the first locator and, by comparison with the latter, closer to the work point, wherein the second locator is designed to detect five degrees of freedom.
A surgical instrument comprising an instrument handle, an instrument shaft connected to the instrument handle, an instrument tip which is connected to the instrument shaft and which has a work point, and a first locator arranged at the instrument handle or the instrument shaft, wherein the first locator is embodied to detect six degrees of freedom and is embodied as a position sensor and has two coils, and the instrument shaft is deflectable between the first locator and the work point during use of the surgical instrument and in that a second locator is arranged at a distance from the first locator and, compared with the latter, closer to the work point, wherein the second locator is embodied to detect only five degrees of freedom and is embodied as a position sensor and has one coil, wherein the second locator has smaller dimensions than the first locator.
A method for detecting the position of a surgical instrument, wherein the instrument has an instrument handle, an instrument shaft which is connected to the instrument handle and which is deflectable during use of the surgical instrument, an instrument tip which is connected to the instrument shaft and which has a work point, and wherein a first locator is assigned to the instrument in a manner that is spatially defined at at least one instant and a second locator is arranged at the instrument in the vicinity of the instrument tip, wherein the second locator is embodied to detect five degrees of freedom, the method comprising the following steps:
