3-UPU/SPS automatic implantation device for cochlea pre-bending electrode

Abstract

The invention discloses a 3-UPU / SPS automatic implantation device for a cochlea pre-bending electrode. The 3-UPU / SPS automatic implantation device comprises a linear guiding wire and a pushing mechanism, wherein the linear guiding wire is prearranged in a guiding hole of a pre-bending electrode and is used for strengthening the pre-bending electrode, and a clamping head is arranged at the outer end of the tail of the pre-bending electrode through the linear guiding wire; the pushing mechanism comprises a guiding wire positioning assembly, an electrode pushing assembly and a three-rotation andone-shift parallel mechanism, the guiding wire positioning assembly is connected with the clamping head, the electrode pushing assembly is connected with the tail end of the pre-bending electrode andis repelled to move by the guiding wire positioning assembly, and the three-rotation and one-shift parallel mechanism is used for bearing and controlling the electrode pushing assembly; the three-rotation and one-shift parallel mechanism comprises an X-axis rotational degree of freedom, a Y-axis rotational degree of freedom, a Z-axis rotational degree of freedom and a Z-axis movement degree of freedom and is used for bearing and controlling the position of an electrode implantation device; and the pushing direction of the electrode pushing assembly is accordant with an X axis and a Y axis. Theadjustment of the initial position of the electrode implantation is realized by virtue of the three-rotation and one-shift parallel mechanism, the pre-bending electrode is inserted and retracted during the implantation and is automatically rotatably adjusted along the axis direction of an cochlea, and accurate control of the position is realized by virtue of relative sensitive force sense perception of a robot mechanism.

Description

technical field [0001] The present invention relates to a kind of implanting device of medical pre-bending electrode, particularly relate to a kind of automatic implanting device of the cochlear pre-bending electrode that adopts 3-UPU / SPS 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 electrod...

Problems solved by technology

[0005] An object of the present invention is to provide an automatic implantation device for cochlear pre-bent electrodes, which pulls out the preset linear guide wires simultaneously in a repulsive manner when pushing the pre-bent electrodes through a repulsive moving structure, which solves the problem of pre-bending When the curved electrode is implanted, both hands are required, the positioning accuracy of the electrode is difficult, and the position adjustment is inconvenient.
