Six-degree-of-freedom automatic implantation device of cochlea pre-bending electrode

Abstract

The present invention discloses a six-degree-of-freedom automatic implantation device of a cochlea pre-bending electrode. The device comprises: a straight guide wire pre-arranged in a guide hole of apre-bending electrode and straightening the pre-bending electrode, wherein the straight guide wire is provided with a clamping head at the outer end of the tail portion of the pre-bending electrode; apush mechanism comprising a guide wire location module connected with the clamping head and an electrode push module connected with the tail end of the pre-bending electrode and configured to performrepulsion movement with the guide wire location module; and a six-degree-of-freedom parallel mechanism, wherein the six-degree-of-freedom parallel mechanism comprises movement freedoms of an X shaft,a Y shaft and a Z shaft and rotation freedoms of the X shaft, the Y shaft and the Z shaft, the push mechanism and the pre-bending electrode are fixed on the six-degree-of-freedom parallel mechanism,and the push direction of the electrode push module is consistent to the X shaft or the Y shaft. The six-degree-of-freedom automatic implantation device of a cochlea pre-bending electrode achieves initial position regulation of electrode implantation, insertion or recycling of the pre-bending electrode in the implantation and automatic rotation regulation in a cochlea axis direction, and the robotmechanism is employed to more sensitively perform force sense perception and achieve accurate control of the position.

Description

technical field [0001] The invention relates to a device for implanting a medical pre-bent electrode, in particular to a six-degree-of-freedom automatic implant device for a cochlear pre-bent electrode using a parallel robot. Background technique [0002] A cochlear implant is an electronic device that converts sound into a coded electrical signal by an external speech processor, and directly stimulates the auditory nerve through the electrode system implanted in the body to restore, improve and rebuild the auditory function of the deaf. Over the past two decades, with the development of high technology, cochlear implants have developed rapidly and have entered clinical application from experimental research. Cochlear implants are now used as a routine method for the treatment of severe deafness to total deafness all over the world. Cochlear implants are currently the most successful biomedical engineering devices. [0003] The pre-bent electrode itself is made into a cochl...
