The apparatus comprises an implant 200, which may be a cochlear implant, having a plurality of electrodes, a memory 102 configured to store instructions and a processor 104 configured to execute the instructions. When executed the apparatus transmits to a pulse generator 110 an electrode operation signal 106 configured to generate a current pulse on a first pair of electrodes of the implant (202-208, fig 2), receive a first impedance signal 108a from a first measurement pair of electrodes due to interaction of the current pulse with the electrically conductive volume. Then receive a second impedance signal 108b from a second measurement pair of electrodes due to interaction with the electrically conductive volume. The first measurement pair of electrodes and the second measurement pair of electrodes are different. The processor then uses a predetermined mapping relationship to determine a distance between an electrode contact surface on the implant and a wall of the electrically conductive volume and output the determined distance. A surgical instrument for implant insertion is also disclosed. [Figure 1 to accompany the abstract]

This invention discloses a drilling path planning method, storage medium, and device for cochlear implantation, belonging to the field of path planning technology in cochlear implantation. This invention solves the problems of low efficiency and easy introduction of path deviation in existing path planning methods. The invention preprocesses preoperative three-dimensional CT images and integrates anatomical structural models to extract three-dimensional spatial geometric information of key tissues within the temporal bone, including the facial nerve and cochlea. Subsequently, combined with prior medical knowledge, the drilling path for the cochlear implant electrode is automatically planned in three-dimensional space to minimize damage to key nerves and ensure surgical safety. The path planning method of this invention is applicable to cochlear implantation surgery assisted by medical robots, significantly reducing reliance on the doctor's subjective judgment, improving the individualized adaptability and efficiency of path design, and effectively avoiding path deviation caused by human subjective judgment. This invention can be applied to path planning in cochlear implantation surgery.

An optical cochlea implant has several laser diodes which are assigned to different sound frequencies and several optical wave guides. A controller activates the laser diodes as a function of a signal describing a sound frequency spectrum in order to generate laser light and to couple the laser light into different ones of the optical wave guides which are designed such as to be suitable for guiding the laser light into different light-sensitive areas of a cochlea. The laser diodes are each activated in several separate pulselets, which individually do not result in a neural activation of the respective light-sensitive area of the cochlea. The duty cycles of the pulselets are not more than 25 %; and the pulselets in which different laser diodes are activated are interleaved in such a way that no more than a quarter of the laser diodes are activated simultaneously.
