Description
Technical field
The present invention relates to a kind of operating equipment more particularly to a kind of artificial cochlea's cranked electrode implanting devices.
Background technique
Whether used artificial cochlear implant electrode is bent by the electrode array connection of front end in the world at present, can be divided into two
Kind: one is straight electrode, another kind is cranked electrode.For normal cochlear structures, straight electrode front end and cochlea it is spiral-shaped
It cannot preferably coincide, due to the elasticity of electrode front end itself, cochlea periphery is biased in entire electrode front end, and stimulated current is caused to expand
It dissipates, power consumption is big, influences effect of stimulation, and be easy to squeeze cochlea inner tissue, causes to damage to cochlea.And the original shape in cranked electrode front end
State is helical form, it stimulates and more concentrate, can improve the resolution capability of language closer to the spiral ganglion cells of cochlea, and
Small power consumption, the disadvantage is that it is inserted directly into cochlea when cannot facilitate operation.For this purpose, the prior art generallys use in cranked electrode front end
Pre-buried support steel core, the method for extract support steel core in insertion when operation facilitate cranked electrode front end and are implanted into cochlea.But by
It to be inserted into the cylindrical hole in the packaging body silica gel of cranked electrode front end in support steel core, and cylindrical hole is long, and very thin, and
Most of operating process is not good state all in improvement of visual effect, the specific situation of insertion is not seen, so that insertion process
Relatively difficult, support steel core, which is easy bending, causes insertion to fail, and is also easy to puncture the packaging body silica gel of cranked electrode front end, destroy curved
The insulating coating of electrode and influence using effect, operate very difficult.
Summary of the invention
In view of the above drawbacks of the prior art, technical problem to be solved by the invention is to provide a kind of artificial cochlea is curved
Cranked electrode front end can be inserted into cochlea by electrode implanting device.
To achieve the above object, the present invention provides a kind of artificial cochlea's cranked electrode implanting devices comprising guide pipe, two
Handle, shaft and its spring, wherein the guide pipe is made of two sections of jurisdiction, and two sections of jurisdiction are placed in two handles respectively
Upper end, two handles are placed in the shaft, which is placed between two handles.
The section of jurisdiction semicircular in shape.
Two handle lower sections are equipped with non-slip groove.
The guide pipe is equipped with notch close to the position of rear end.
Artificial cochlea's cranked electrode implanting device further includes electrode fork, and electrode fork includes lever and plug, wherein the plug
It is Y-shaped.
The cochlea that artificial cochlea's cranked electrode implanting device of the present invention completes cranked electrode bending part by setting guide pipe is inserted
Enter, whole process is easy to learn, is convenient for upper hand, and without the placement support steel core in cranked electrode, saved cost, improved
Completeness is not easy to go wrong.
It is described further below with reference to technical effect of the attached drawing to design of the invention, specific structure and generation, with
It is fully understood from the purpose of the present invention, feature and effect.

Specific embodiment
The invention will be further elaborated with reference to the accompanying drawing.
As shown in Figure 1, the present invention provides a kind of artificial cochlea's cranked electrode implanting device, including guide pipe 1, two handles 2,
Shaft 3 and its spring 4, wherein the guide pipe 1 is placed in two 2 upper ends of handle, and two handles 2 are placed in the shaft
On 3, the upper end of two handles 2 is allowed to separate or merge around the shaft 3, two 2 lower sections of handle are equipped with anti-skidding
Groove 21 is held with facilitating, which is placed between two handles 2, and the elastic force of the spring 4 makes under natural conditions, and two
The upper end of a handle 2 keeps merging phase.
The guide pipe 1 is made of two semicircle sections of jurisdiction 11, and two sections of jurisdiction 11 are placed in respectively on two handles 2
End, when two 2 upper ends of handle separate, two sections of jurisdiction 11 are also separated；When two 2 upper ends of handle merge, two should
Section of jurisdiction 11 also merges.
The guide pipe 1 is equipped with notch 12 close to the position of rear end, in this way, even if two sections of jurisdiction 11 are in merging phase,
The guide pipe 1 is also exposed inside the position of rear end, to facilitate operation.
As shown in Figures 2 and 3, which further includes the electrode fork 5 of auxiliary, 5 packet of electrode fork
Include lever 51 and plug 52, wherein the plug 52 is Y-shaped, i.e. head end bifurcated is opened.
When using artificial cochlea's cranked electrode implanting device, firstly, mediating two 2 lower sections of handle, which is compressed,
The upper end separation of two handles 2, i.e., two section of jurisdiction 11 separation；Secondly, as shown in Figures 4 and 5, by the straight part of cranked electrode
A is placed between two sections of jurisdiction 11, and the curved part B of cranked electrode is placed in front of two sections of jurisdiction 11, unclamps two 2 lower sections of handle,
Under the elastic acting force of the spring 4, the upper end of two handles 2 merges, i.e., two sections of jurisdiction 11 merge；Then, such as Fig. 6 institute
Show, by cranked electrode toward post-tensioning, so that the curved part B of cranked electrode is fully retracted in the guide pipe 1, at this point, cranked electrode is curved
Part B is straightened due to the constraint by the guide pipe 1；Finally, as shown in Figures 7 and 8, utilizing the plug 52 of electrode fork 5
The annulus C on cranked electrode is pushed, stretches out the curved part B of cranked electrode from the guide pipe 1, it is to be curved hence into cochlea
After the part B of electrode bending fully enters cochlea, again by two section of jurisdiction 11 separation to remove artificial cochlea's cranked electrode
Implanting device.
The preferred embodiment of the present invention has been described in detail above.It should be appreciated that those skilled in the art without
It needs creative work according to the present invention can conceive and makes many modifications and variations.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical solution, all should be within the scope of protection determined by the claims.
