Artificial cochlea pre-bent electrode implantation device and method thereof

Abstract

The invention provides an artificial cochlea pre-bent electrode implantation device, which is characterized in that a hard electrode support piece is arranged in an artificial cochlea pre-bent electrode and can be taken out from a first end of the artificial cochlea pre-bent electrode, and the implantation device comprises an electrode guide mechanism used for supporting the artificial cochlea pre-bent electrode and guiding the artificial cochlea pre-bent electrode; a pre-bent electrode control mechanism used for clamping and driving the artificial cochlea pre-bent electrode to move towards the second end of the artificial cochlea pre-bent electrode; and a supporting piece control mechanism, wherein the first end of the supporting piece control mechanism is fixedly connected with the electrode guide mechanism, and the supporting piece control mechanism is used for clamping the electrode supporting piece located outside the artificial cochlea pre-bent electrode and driving the electrodesupporting piece to move towards the first end of the artificial cochlea pre-bent electrode.

Description

Technical field [0001] The invention relates to the field of medical equipment, in particular to an artificial cochlear pre-curved electrode implantation device and method. Background technique [0002] Cochlear implant is an implantable hearing aid device, including an implanted part and an external part. The implanted part is composed of a signal receiving and decoding module, a stimulation electrode array, and the external part is composed of a microphone, a voice processor, and a signal transmitter for sending instructions to the implanted part. The doctor implants stimulating electrodes into the cochlea, and applies electrical stimulation to the auditory nerves in the cochlea that are still intact through the electrodes, so that patients with severe hearing loss can produce certain sound perception. [0003] The traditional cochlear implant electrode is a soft straight electrode, which relies on the interaction with the cochlear wall during implantation to realize the bending...

Problems solved by technology

[0005] However, since the pre-bent electrode requires high cooperation of both hands of the surgeon during the implantation process, in a narrow surgical space, one hand pushes the electrode, and the other hand stabilizes and pulls out the electrode support (such as Figure 2A to Figure 2C As shown), the requirements for the surgeon are high, the operation is extremely challenging, and it is easy to make mistakes in the cooperation of both hands, which will cause damage to the fine structure of the inner ear and affect the implantation effect.

The existing implant devices designed for cochlear implant pre-bent electrodes are not highly automated, which is not conducive to hand-held operation, and it is not convenient to modify based on existing otological robots
