Description

Technical Field

[0001] The invention relates to the field of biomedical bionics, and in particular to a split-type artificial hearing implant device and a connection structure of the implant device. Background Art

[0002] Hearing implants are an effective method of hearing reconstruction for severe or profound sensorineural hearing loss in both ears. Artificial hearing implants mainly include cochlear implants (CI) and auditory brainstem implants (ABI). Cochlear implants are suitable for deaf patients with normal development of the cochlear nerve and no obvious severe malformations of the cochlear structure. Auditory brainstem implants are suitable for patients who are not suitable for cochlear implants, such as those with underdeveloped cochlea, cochlear ossification, absent auditory nerve, neurofibromatosis type 2, etc. Traditional hearing implant devices are divided into an external part (speech processor, etc.) and an internal part, where the internal part includes a receiving processor implant and implanted electrodes.

[0003] Taking the cochlear implant as an example, its working principle is that the microphone part of the external device first collects the sound, and then the speech processor encodes the sound information into electrical information (the above is the external part), and the coil is transmitted through the skin to the receiving processor in the body (the following is the internal part), and then the processed signal is transmitted to the implanted electrode (implanted in the cochlea), and the electrode stimulates the inner ear sensory tissue to produce hearing. The stimulation process of artificial hearing brainstem electrode implantation is basically the same as that of the cochlear implant, but the electrode is implanted in the cochlear nucleus of the brainstem.

[0004] Both cochlear implants and artificial auditory brainstem implants will encounter the problem of implant damage during actual use, especially the receiving processor part implanted in the body.

[0005] At present, more than 60% of the cochlear implant recipients in China are children. The internal part of the receiver processor implant is buried in a shallow position under the skin behind the ear, which is easily affected by trauma, resulting in implant damage and affecting the use of the cochlear implant. In this case, surgery is usually required to remove the entire internal part, including the receiver processor implant and the implant electrode, but the electrode part implanted in the cochlea is often still intact at this time, and the electrode is also surrounded by the surrounding connective tissue. When removing the electrode, it is easy to involve and damage the surrounding delicate sound sensory tissue, which will also hinder the re-implantation of the electrode and affect the hearing effect after re-implantation.

[0006] In addition, because the artificial auditory brainstem implant surgery is an intracranial surgery, the risk is much greater than cochlear implant (middle ear and inner ear surgery), and it is necessary to open the skull and expose the brainstem to implant the electrode. If the implant is partially damaged and affects the electrode, it is necessary to perform a craniotomy again at a greater risk. In addition, for adult patients with neurofibromatosis type 2, although the probability of implant damage caused by trauma is low, the position of the electrode in the brainstem may be displaced and ineffective due to the compression of the tumor. Therefore, sometimes the implant under the skin behind the ear is normal, but the electrode position needs to be adjusted or even replaced. Summary of the invention

[0007] The present invention provides a split-type artificial hearing implant device and a connecting mechanism for the implant device. The split-type connecting structure realizes a detachable connection between an electrode portion of an in vivo implanted portion and an implant body in the artificial hearing implant device, thereby avoiding the need to replace the in vivo implanted portion as a whole, preventing damage to the ultrafine auditory structures of the cochlea, brainstem and other locations of the brain when electrodes are removed, reducing adverse reactions after surgery and improving the patient's hearing reconstruction effect.

[0050] The following is based on Figures 1 to 13 , specifically describe the preferred embodiments of the present invention.

[0051] like Figure 1 As shown, the present invention provides an artificial hearing implant device, comprising an external part 1 and an internal implant part 2, the external part 1 comprising a microphone 11 and a processor 12, the internal implant part 2 comprising an implant body 21 and an electrode part 23 connected by an electrode connecting line 22, the electrode part 23 being implanted in the cochlea or the cochlear nucleus of the brainstem, and the electrode part 23 being connected to the implant body 21 via a split connection structure 24.

[0052] The electrode of the cochlear implant acts on the cochlea. The microphone 11 collects sound, and the processor 12 encodes the sound information into electrical information, which is transmitted through the coil to the implant 21 through the skin. After the information is decoded by the implant 21, it is transmitted to the cochlea through the electrode part 23, and then transmitted to the cochlear nucleus of the brainstem and the auditory center of the cerebral cortex through the auditory nerve, producing meaningful hearing.

[0053] Auditory brainstem implantation is to implant the electrode part 23 directly into the cochlear nucleus of the brainstem. The microphone 11 collects sound, and the processor 12 encodes the sound information into electrical information, which is transmitted percutaneously to the implant 21 by the coil. After the information is decoded by the implant 21, it bypasses the human cochlea and auditory nerve and directly reaches the cochlear nucleus of the brainstem through the electrode part 23.

[0054] The present invention sets the connection between the implant 21 and the electrode part 23 from a fixed connection to a split detachable connection, and realizes the detachable connection between the electrode part 23 and the implant 21 through a split connection structure 24. When in normal use, the electrode part 23 and the implant 21 transmit electrical information normally. If any part of the implant 21 or the electrode part 23 is damaged and needs to be replaced, the electrode part 23 and the implant 21 are separated through the split connection structure 24, and the electrode part 23 or the implant 21 is replaced. After replacement, the electrode part 23 and the implant 21 are reconnected through the split connection structure 24. By setting the split connection structure 24 to realize the detachable connection between the electrode part 23 and the implant 21, whichever part is damaged can be replaced, avoiding the overall replacement of the implant part 2 in the body, preventing damage to the cochlea, brainstem and other parts of the brain, reducing surgical risks, and improving the cure rate of patients.

[0055] The split connection structure 24 provided by the present invention further includes: an electrode connection line connection port and an implant connection port, wherein the electrode connection line connection port is arranged at the end of the electrode connection line 22, and the implant connection port is arranged in the implant, and the electrode connection line connection port can be inserted into the implant connection port, and the electrode connection line connection port and the implant connection port are snap-connected, and the electrode connection line connection port is inserted into the implant connection port to complete the connection between the electrode part 23 and the implant 21, and the in vivo implanted part of the artificial hearing implant device can work normally. When the electrode part 23 or the implant 21 needs to be replaced, the electrode connection line connection port and the implant connection port are detached, and the electrode part 23 is separated from the implant 21, and the electrode part 23 or the implant 21 can be replaced separately.

[0056] like Figure 2 and Figure 3 As shown, the electrode connection line connection port specifically includes:

[0057] A connector 201 connected to the electrode connecting wire 22, and the connector 201 is provided with an inwardly recessed locking bayonet 204;

[0058] A chip layer 203 extending from the electrode connection line 22 to the connector 201 , wherein the chip layer 203 is exposed on the surface of the connector 201 ;

[0059] The sealing layer 202 wraps around the connection between the connector 201 and the electrode connection line 22 and is used to isolate and seal the chip layer 203 to prevent the chip layer from being exposed to the in vivo environment.

[0060] In one embodiment of the present invention, the electrode connection line connection port is a columnar structure, and its cross section can be of any shape. The sealing layer 202 is made of waterproof material to prevent water from entering the chip layer 203 and causing a short circuit. At the same time, the electrode connection line connection port can be fastened to the implant connection port. The setting position of the sealing layer should match the length of the connection tube 205, so that after the electrode connection line connection port is embedded in the implant connection port, the sealing layer is located at the tube mouth of the connection tube 205, thereby better realizing the sealing function.

[0061] like Figure 4 and Figure 5 As shown, the implant connection port specifically includes:

[0062] The connecting tube 205 is used to accommodate the electrode connecting line connection port and realize the connection with the electrode connecting line connection port. A chip reading head is arranged inside the connecting tube 205, which contacts the chip layer 203 on the electrode connecting line connection port to realize the circuit connection between the implant and the electrode part;

[0063] A limiting mechanism 206, which is used to limit the movement range of the electrode connection line connection port;

[0064] A locking mechanism 207, which is used to lock and fix the electrode connection line connection port;

[0065] The transmission control mechanism 208 is used to open the locking mechanism to achieve the separation of the electrode connection line connection port from the connection tube 205.

[0066] like Figure 5 As shown, in one embodiment of the present invention, the locking mechanism 207 comprises:

[0067] A push plate 209, which is disposed between the connecting tube 205 and the limiting mechanism 206 and can move in the space between the connecting tube 205 and the limiting mechanism 206;

[0068] The locking clip 210 is movably connected to the two ends of the push plate 209. One end of each locking clip 210 is movably connected to one end of the push plate 209 and rotates around the connection point as the rotation axis. The other end of each locking clip 210 has a locking protrusion 211, and the shape of the locking protrusion 211 matches the shape of the locking bayonet 204 on the connector 201.

[0069] like Figure 6 As shown, the connecting pipe 205 comprises:

[0070] The cylindrical tube body 2051 has a shape matching the shape of the electrode connection line connection port and is used to accommodate the electrode connection line connection port;

[0071] The locking holes 2052 are arranged on the columnar tube 2051 and serve as a passage to facilitate the locking clip 210 in the locking mechanism 207 to be inserted into the locking bayonet 204 on the connector 201. The number, arrangement position, shape and size of the locking holes 2052 match those of the locking bayonet 204 on the connector 201.

[0072] The slide groove 2053 is arranged at one end of the columnar tube body 2051 close to the limiting mechanism 206, and is used to accommodate the propulsion plate 209 to facilitate the spatial movement of the propulsion plate 209 between the connecting tube 205 and the limiting mechanism 206. The size and shape of the slide groove 2053 match the size and shape of the propulsion plate 209.

[0073] like Figure 7 As shown, the limiting mechanism 206 includes:

[0074] A limit baffle 2061, which is arranged at the end of the connecting pipe 205;

[0075] A step surface 2062, which is provided on the limit baffle 2061 and is used to fix the connecting pipe 205, and the size and shape of the step surface 2062 match the size and shape of the connecting pipe 205;

[0076] A groove 2063 is provided on the limit baffle 2061 and is used to accommodate the locking mechanism 207. The number, location, shape and size of the groove 2063 are matched with the locking mechanism 207;

[0077] The through hole 2064 is disposed on the step surface 2062 and is used to accommodate the transmission control mechanism 208 so that the transmission control mechanism 208 can contact the locking mechanism 207 .

[0078] In one embodiment of the present invention, the connecting tube 205 and the limiting mechanism 206 may be two independent parts. During assembly, the end of the connecting tube 205 is embedded in the step surface 2062 of the limiting mechanism 206 for fixation, and the push plate 209 is disposed in the space between the connecting tube 205 and the limiting mechanism 206. In another embodiment of the present invention, the connecting tube 205 and the limiting mechanism 206 are integrally formed, and the push plate 209 is disposed in the space between the connecting tube 205 and the limiting mechanism 206.

[0079] like Figure 8 As shown, in one embodiment of the present invention, the transmission control mechanism 208 comprises:

[0080] The slider rack 2081 has one end passing through the through hole 2064 on the limiting mechanism 206 and in contact with the push plate 209 in the locking mechanism 207, and the rack structure at the other end meshes with the steering gear set;

[0081] A steering gear set, comprising a first gear 2082 and a second gear 2083 meshing perpendicularly with each other, wherein the first gear 2082 meshes with the slider rack 2081 and the second gear 2083 respectively, and the second gear 2083 meshes with the first gear 2082 and the control rack 2084 respectively;

[0082] The control rack 2084 has a rack structure at one end that meshes with the steering gear set and a button at the other end.

[0083] The working principle of the split connection structure of an artificial hearing implant device provided by the present invention is as follows:

[0084] like Fig. 9 As shown, when the electrode connection port is inserted into the implant connection port, the electrode connection port is inserted as a whole into the connection tube 205, the connector 201 contacts the push plate 209, and applies thrust to the push plate 209, the push plate 209 moves toward the limit mechanism 206, and the push plate 209 stops after touching the limit mechanism 206. The locking clip 210 is connected to the push plate 209 by the connecting screw 211. During the movement of the push plate 209, the locking clip 210 is rotated toward the connection tube 205 with the connecting screw 211 as the rotation axis until the locking protrusion 211 on the locking clip 210 passes through the locking hole 2052 on the connection tube 205 and is embedded in the locking bayonet 204 on the connector 201, and the locking of the electrode connection port and the implant connection port is completed. During the movement of the push plate 209, the push plate 209 pushes the slider rack 2081 to move, and the rack structure at the tail end of the slider rack 2081 pushes the first gear 2082 to rotate counterclockwise, thereby driving the second gear 2083 to rotate clockwise, and the control rack 2084 is lifted through the rack structure.

[0085] like Fig.10 As shown, when the electrode connection line connection port is separated from the implant connection port, the control rack 2084 is pressed to drive the second gear 2083 to rotate counterclockwise, and then drive the first gear 2082 to rotate clockwise. The rack structure at the tail end of the slider rack 2081 pushes the slider rack 2081 to move toward the limit mechanism 206, and the slider rack 2081 pushes the push plate 209 to leave the limit mechanism 206. During the movement of the push plate 209, the locking protrusion 211 on the locking clip 210 is forced to disengage from the locking bayonet 204 on the connector 201. The locking clip 210 opens to both sides with the connecting screw 211 as the rotation axis. During the movement of the push plate 209, a thrust is applied to the connector 201, forcing the electrode connection line connection port to disengage from the connecting tube 205.

[0086] like Fig.11 and Fig.12As shown, in another embodiment of the present invention, the transmission control mechanism 208 comprises:

[0087] The bow-shaped spring piece 213 has a deformable main body part 214 and extension parts 215 connected to both ends of the deformable main body part 214. The extension parts 215 are respectively in contact with a locking clip 210. The bow-shaped spring piece 213 has elastic deformation capability, that is, the deformable main body part 214 can be deformed when subjected to force, and can return to its original shape when the external force disappears;

[0088] The control button 212 contacts the bow-shaped spring piece 213 and is used to apply external force to the bow-shaped spring piece 213 to deform it. In this embodiment, the control button 212 can be set on the connecting tube 205. Accordingly, a through hole can be set on the connecting tube 205 so that the control button 212 passes through the through hole on the connecting tube 205 and contacts the deformed main body 214 of the bow-shaped spring piece 213. The connecting tube 205 plays a role in supporting the control button 212.

[0089] The working principle of the split connection structure of an artificial hearing implant device provided by the present invention is as follows:

[0090] When the electrode connection port is inserted into the implant connection port, the electrode connection port is inserted as a whole into the connection tube 205, the connector 201 contacts the push plate 209, and applies thrust to the push plate 209, the push plate 209 moves toward the limit mechanism 206, and stops after the push plate 209 touches the limit mechanism 206. The locking clip 210 is connected to the push plate 209 by the connecting screw 211. During the movement of the push plate 209, the locking clip 210 is rotated toward the connection tube 205 with the connecting screw 211 as the rotation axis, until the locking protrusion 211 on the locking clip 210 passes through the locking hole 2052 on the connection tube 205 and is embedded in the locking bayonet 204 on the connector 201, and the locking of the electrode connection port and the implant connection port is completed.

[0091] like Fig.13As shown, when the electrode connection line connection port is separated from the implant connection port, the control button 212 is pressed, and the control button 212 contacts the bow-shaped spring piece 213, and applies pressure to the deformed main body 214 of the bow-shaped spring piece 213, and the deformed main body 214 is deformed, and the force perpendicular to the bow-shaped spring piece 213 is converted into a force parallel to the bow-shaped spring piece 213, and the bow-shaped spring piece 213 is extended as a whole, and the extension part 215 extends toward the locking clip 210, pushing the locking clip 210 to open to both sides with the connecting screw 211 as the rotation axis, thereby releasing the electrode connection line port. The present invention sets the connection between the implant body and the electrode part of the in-vivo implant part in the artificial hearing implant device from a fixed connection to a split-type detachable connection, and realizes the detachable connection between the electrode part and the implant body through the split connection structure. If either the electrode part or the implant body is damaged, that part is replaced, thereby avoiding the need to replace the in-vivo implant part as a whole. The present invention is suitable for both artificial cochlear implantation and auditory brainstem implantation, preventing damage to the cochlea, brainstem and other parts of the brain, reducing surgical risks and improving the cure rate of patients.
