Description

Technical Field

[0001] The utility model relates to a simple auxiliary device for implanting artificial cochlear electrodes, belonging to the field of mechanical equipment. Background Art

[0002] Electrode (see Appendix Figure 1 , Attachment Figure 2 Component 1) Implantation is the most critical step in cochlear implantation, which requires the most gentle operation to maximize the protection of the fine structure of the inner ear and residual hearing. Some scholars have proposed that the overall implantation of the electrode should be completed slowly within 1-2 minutes, but it is often difficult to achieve in actual bare-handed operation.

[0003] In the prior art, cochlear electrodes are usually implanted manually by doctors. The electrodes in the cochlea are very small, which requires high micromanipulation ability of the doctor and can easily cause clinical "pain points" such as facial nerve damage, cochlear damage and poor consistency of surgical results.

[0004] The spiral plate of the basilar membrane is delicate and can be ruptured by an external force of more than 100mN, while the force control accuracy of human bare hands can only reach about 256mN. Therefore, the current technology for preserving the fine structure of the inner ear during cochlear implantation is highly dependent on the operator's experience, physical strength and other factors, which has become a bottleneck restricting the further improvement of the overall efficacy of cochlear implantation.

[0005] Therefore, it is necessary to design an auxiliary device for the implantation of cochlear implant electrodes to facilitate doctors' manual operation and improve the efficiency and effectiveness of implantation. Utility Model Content

[0079] Specifically, a follower shaft mounting hole 324 is provided at the front of the follower clamp component 32, and the axis of the follower shaft mounting hole 324 is perpendicular to the axis of the electrode guide groove 36; the follower shaft 327 passes through the follower shaft mounting hole 324, and its part located in the roller mounting cavity passes through the follower wheel 325; the follower shaft mounting hole 324 is located on both sides of the roller mounting cavity, and at least one side is interference fit with the follower shaft 327; the follower shaft 327 and the follower wheel 325 have a transition fit, or a clearance fit, so that the follower wheel 325 can rotate freely around the follower shaft 327.

[0080] Further references Fig.12 ,and Figure 13-Figure 15 The driving clamping part 31 and the following clamping part 32 are installed together through the clamping pin 33 and the torsion spring 34 to form a clamp-like structure; by pinching the driving side operating part 313 and the following side operating part 323 of the two, the front working part can be opened to form an opening, which is convenient for loading the electrode 12; then, the driving side operating part 313 and the following side operating part 323 are released, and the torsion spring 34 applies force to close the working part, clamping the electrode 12 between the driving wheel 315 and the following wheel 325, and the electrode guide groove 36 plays a guiding role in the process; By rotating the rotating wheel 41, the driving wheel 315 can be driven to rotate, thereby rubbing the electrode 12 to move; and during the process, the follower wheel 325 always presses against the electrode under the action of the torsion spring 34, so that it is always attached to the driving wheel 315, providing appropriate pressure and generating sufficient friction to achieve movement; during operation, the simple device 3 for implanting a cochlear implant electrode of the utility model can be pressed against the external auricle, so that the doctor can control the implantation speed and strength of the electrode by slowly rotating the rotating wheel 41, which is more convenient to operate.
