Embodiment Construction

[0014] See attached figure 1 ~ attached figure 2 , the present invention is composed of a cochlear implant device 1 encapsulated by silicone colloid 4. The cochlear implant device 1 is composed of a decoder 6 and a stimulating electrode 7. The cochlear implant device 1 is provided with lugs 5, the lugs 5 corresponds to the silicone colloid 4 arranged on both sides of the decoder 6 and is integrated with the silicone colloid 4; the self-tapping screw 2 provided with the fixing part 3 is embedded in the lug 5, and the self-tapping screw 2 and the fixing part 3 are a set And the countersunk head is set on the lug 5; the self-tapping screw 2 is made of titanium material conforming to the national standard GB / T 13810-1997 "Processing Regulations on Titanium and Titanium Alloys for Surgical Implants", and the self-tapping screw 2 is embedded in the convex lug 5. Ear 5 is not easy to lose in the silicone.

[0015] See attached image 3 , the fixing part 3 is a round gasket made o...

Abstract

The invention discloses an artificial cochlea implanting device with fixing members. The artificial cochlea implanting device is packaged by colloidal silica bodies and is characterized in that lugs are arranged on the colloidal silica bodies on two sides of the artificial cochlea implanting device and integrated with the colloidal silica bodies; and tapering screws with fixing members are embedded in the lugs, the tapering screws and the fixed members are sleeved together, and countersunk is arranged on the lugs. Compared with the prior art, the artificial cochlea implanting device is simple in structure and convenient and reliable to fix, an implanted artificial cochlea cannot displace in a human body, and an stimulation electrode cannot dislocate, so that reliability and safety are further improved, and the hazard that the stimulation electrode cannot work normally after operation caused by the fact that a decoder gets out of an installation groove and rotates in the groove is avoided.

Description

technical field [0001] The invention relates to the technical field of artificial organ implantation devices, in particular to an artificial cochlear implantation device provided with screw fixing parts. Background technique [0002] The cochlear implant is an electronic device with a high content of bionics science and technology at present, and it is mainly used to help patients with severe or extremely severe deafness who wear hearing aids that are not effective or effective at all. At present, the cochlear implantation device generally does not add auxiliary fixation during the operation process. Even if auxiliary fixation is added, it is to use low-strength sutures, surgical medical quick-adhesive glue or strip-shaped titanium plates to assist artificial fixation. Cochlear implant device. Fixing the implant device with sutures has low fixation strength and short service life, and the fixation with sutures also has the problem of biocompatibility. The use of surgical m...
