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
The present invention relates to artificial organ implanting device technical field, specifically a kind of artificial cochlea implanting device that is provided with the screw fixture.
Background technology
The artificial cochlea is the higher a kind of electronic installation of present bionics scientific and technological content, is mainly used in the severe, the utmost point severe deafness patient that help the hearing aids effect bad or absolutely void.At present, artificial cochlea implanting device is in operation process, generally be not increase auxiliary fixing, even increase auxiliary fixing, namely adopt the not high stitching thread of intensity, the medical quick-binding glue of surgery or strip titanium plate to be assisted fixedly artificial cochlea implanting device.Adopt stitching thread fixedly implanting device exist that constant intensity is low, the life-span short, and stitching thread is fixed the problem that also has biocompatibility.Adopt fixedly implanting device of the medical quick-binding glue of surgery, because the glue adhesion strength is inadequate, cause easily the problems such as the artificial cochlea is subjected to displacement, stimulating electrode dislocation in human body.Adopt fixedly implanting device of strip titanium plate, strip titanium plate only carries out nonholonomic constraints to decoder to be fixed, and strip titanium plate can not adapt to the profile of artificial cochlea implanting device, and fixed effect is relatively poor.
The application of implanting along with the artificial cochlea is more and more extensive, the fixation problem that presents implanting device is even more important, with regard to known case, because solid failure causes the artificial organ cisco unity malfunction implanted, even cause possible permanent damage even dead accident to happen occasionally to human body, for these human body implanting device, need to there be a kind of i.e. safety to implant reliably again fixed form and guarantees its long-time steady operation in human body.Prior art can't guarantee that the artificial cochlea is implanted in long-time steady operation in the human body, causes easily the inefficacy of artificial cochlea implanting device, therefore needs a kind of safe, reliably, fixing means improves the reliability of artificial cochlea implanting device easily.
Summary of the invention
A kind of artificial cochlea implanting device that is provided with fixture of providing for the deficiencies in the prior art is provided, it adopts the fixedly packaging body of ear-hang of screw, so that the artificial cochlea can not be subjected to displacement the problem of dislocating with stimulating electrode in human body, further improved artificial cochlea's reliability and safety.
The concrete technical scheme that realizes the object of the invention is: a kind of artificial cochlea implanting device that is provided with fixture, comprise the artificial cochlea implanting device by the colloidal silica encapsulation, artificial cochlea implanting device is comprised of decoder and stimulating electrode, the colloidal silica that is characterized in the artificial cochlea implanting device both sides is provided with lug, and lug and colloidal silica are integrated; Described lug is embedded in the tapping screw that is provided with fixture, and tapping screw and fixture suit and countersunk head are arranged on the lug.
Described fixture is the ring washer that the titanium material is made, and its center is provided with screw hole, and both sides are provided with flange, and screw hole one end is provided with groove.
Described tapping screw is that the titanium material is made.
Described lug correspondence is arranged on the colloidal silica of decoder both sides.
The present invention compared with prior art has simple in structure, convenient fixing, reliable, the artificial cochlea can not be subjected to displacement with stimulating electrode in human body and dislocate, artificial cochlea's reliability and safety have further been improved, avoided causing the hidden danger of postoperative stimulating electrode cisco unity malfunction because decoder is deviate from mounting groove or rotate the drive stimulating electrode in groove.

The specific embodiment
Consult accompanying drawing 1 ~ accompanying drawing 2, the present invention is made of the artificial cochlea implanting device 1 of colloidal silica 4 encapsulation, artificial cochlea implanting device 1 is comprised of decoder 6 and stimulating electrode 7, described artificial cochlea implanting device 1 is provided with lug 5, and lug 5 correspondences are arranged on the colloidal silica 4 of decoder 6 both sides and with colloidal silica 4 and are integrated; Described lug 5 is embedded in the tapping screw 2 that is provided with fixture 3, and tapping screw 2 is that suit and countersunk head are arranged on the lug 5 with fixture 3; Described tapping screw 2 is made for the titanium material that meets GB GB/T 13810-1997 " surgical implant is stipulated with titanium and its alloy work ", and tapping screw 2 is embedded in the silica gel of lug 5 and is not easy to lose.
Consult accompanying drawing 3, the ring washer that described fixture 3 is made for the titanium material, its center is provided with screw hole 31, both sides are provided with flange 32, screw hole 31 1 ends are provided with groove 33, fixture 3 is made for the titanium material that meets GB GB/T 13810-1997 " surgical implant is stipulated with titanium and its alloy work ", two side flanges 32 are fixed on fixture 3 in the colloidal silica 4 and can't rotate or move up and down, fixture 3 can strengthen the intensity that artificial cochlea implanting device 1 is connected with tapping screw 2, has also avoided the damage of 2 pairs of colloidal silicas 4 of tapping screw.
Consult accompanying drawing 4, the present invention installs like this: the overall dimensions according to decoder 6 grinds a circular decoder mounting groove 9 at patient's temporal bone 8, between mastoid cavity, grind bone groove 10 and open surface crypts with electric drill at decoder mounting groove 9, below the cochlea vestibuli, locate to seek and the location oeil de boeuf for 2 millimeters, in the front lower place of oeil de boeuf with diamond low speed to the capable cochlea windowing of tympanic canal and open cochlea and expose patchhole 11.
By said method with decoder 6 solid and reliable being fixed on the temporal bone 8, can prevent that decoder 6 from deviating from the human body intrinsic displacement or in decoder mounting groove 9, drive stimulating electrode 7 or pull stimulating electrode 7 thereby produce disturbance, affect the installation effect of stimulating electrode 7.Because what tapping screw 2 adopted is countersunk head, its surface was very smooth after artificial cochlea implanting device 1 was fixing, thus scalp and artificial cochlea implanting device 1 can extraordinaryly fit, very close to each other, reduced greatly the probability of postoperative infection.
More than just the present invention is further illustrated, is not to limit this patent, all for the present invention's equivalence enforcement, all should be contained within the claim scope of this patent.
