A cochlear curved electrode implanter

Abstract

The invention discloses an artificial cochlea cranked electrode implanting machine which comprises an implanting handle and a catheter arranged on the implanting handle. The catheter is provided with an open groove, a positioning open ring is arranged at one end of the catheter, a reinforcing open ring group is arranged at the other end of the catheter, the catheter is connected with a push rod in an inserted manner, the push rod is provided with a limiting block, a push rod handle is arranged at the tail of the push rod, and a portion where the push rod handle is connected with the push rod is a bending portion. The artificial cochlea cranked electrode implanting machine is simple in structure, convenient to use and capable of safely implanting a cranked electrode into a cochlea.

Description

technical field [0001] The invention relates to an implanter, in particular to a cochlear bend electrode implanter. Background technique [0002] A cochlear implant is an electronic device that converts sound into electrical signals in a certain coded form by an external speech processor, and directly excites the auditory nerve through the electrode system implanted in the body to restore or reconstruct the auditory function of the deaf. In recent years, with the development of electronic technology, computer technology, phonetics, electrophysiology, materials science, and ear microsurgery, cochlear implants 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. At present, the cochlear implant electrodes used in the world are divided into two categories: straight electrodes and curved electrodes. Direct electrodes cannot achieve near-cochlea...

AI Technical Summary

Problems solved by technology

Direct electrode can not stimulate near the cochlear modiole, and may damage the cochlea when implanted

The implantation of curved electrodes is inconvenient. If the electrodes are not straightened before implantation, they cannot be implanted in the cochlea. Therefore, most of the outer cores are pre-embedded when the electrodes are connected. The electrode is stretched straight, and the supporting inner core is pulled out while inserting during the operation. The electrode insertion and the supporting steel core pulling out should be synchronized. If the electrode is inserted too fast, it may damage the cochlea or bend the supporting steel core. The electrode head hooked back and got stuck in the cochlea and could no longer be implanted in the cochlea. Since the support core could not be inserted back into the electrode after being pulled out, the electrode could no longer be inserted into the cochlea. Only a set of implants could be replaced for implantation, which resulted in the interruption of the operation. If the time is long, the damage to the cochlea will be aggravated; at the same time, the visual effect during the operation is not good, and the specific situation of the insertion cannot be seen clearly, and it is easy to scratch the electrode silica gel and the electrode wire insulation layer, causing the electrodes to short circuit; due to the support core, the electrode array is thick, It is difficult to make a slender shape, which affects the implantation depth; there is no good implantation tool and method to safely implant the curved electrode in the cochlea
