Description
Technical field
Invention is related to medical instruments field, artificial cochlea's surgical skin flap drag hook of especially a kind of included suction device.
Background technique
Artificial cochlea is a kind of electronic bio device developed according to cochlea physiology principle, is medicine, biomedicine, hearing
, materialogy, microelectronics, mechanics combine across multi-disciplinary new high-tech product.Artificial cochlea can replace lesion
Impaired hearing organ is passed to the ear of human body by the electric signal that external speech processor converts sound into certain coding form
Snail, by the acoustic fibers of the electrode system distribution of stimuli that implants there, directly excitement auditory nerve, Lai Huifu or again
Build the auditory function of deaf person.Artificial cochlea is one of important achievement of modern medicine, for severe or pole severe deafness, artitificial ear
The implantation of snail is unique the having that can make bilateral severe or the recovery sense of hearing of pole severe patients with sensorineural hearing loss internationally recognized at present
Imitate device.
Implantation process, that is, artitificial ear implantation of artificial cochlea.Artificial cochlear implant is the important operation in otology field,
In cochlear implant implantation process, the processor of cochlear implant should be placed on the bone slot of implantation side temporal bone.After not expanding ear
The temporal bone that mastoid process back upper place is sufficiently exposed under conditions of notch is particularly important.Artificial cochlea perform the operation cochlea electric drill production receive/
During stimulator bone bed, drill speed is exceedingly fast and very sharp, easy sliding in operating process, thus above the bone slot of damage
Flap, cause flap bleeding even postoperative necrosis；In addition, since surgical field of view deep light is difficult to reach, in addition boring mill cranium
The electric drill of bone can generate a large amount of bone meal, cause surgical field of view poor, seriously affect the accuracy and efficiency of surgical procedure.At present
Such drag hook equipment of clinical use is department of general surgery's routine drag hook, and volume is larger, is difficult in limited operative space effectively sudden and violent
Dew is easy to influence the visual field of doctor；And do not have synchronous attraction function, need more hand operations that can realize.
Summary of the invention
The technical problems to be solved by the invention are exactly to be in view of the deficiency of the prior art, to provide one kind and be convenient for
Sufficiently exposure electric drill makes receiving/stimulator bone bed, and can protect temporalis flap, reduces surgical injury and bleeding.Lead to simultaneously
The salt water for rinsing bone meal can be rapidly and accurately sucked out with adequate illumination, included suction tube by crossing fiber plant, be not only convenient for
Surgical exposure visual area is clear, has the function of saving power again according further to the telescoping handle that patient is voluntarily adjusted, reduces overexertion
And cause artificial cochlea's surgical skin flap drag hook of the included suction device of patient trauma.
The technical solution adopted by the present invention to solve the technical problems is: a kind of artificial cochlea's operation of included suction device
With flap drag hook, artificial cochlea's operation retractor includes handle end, drag hook end and attraction pipeline；The handle end and the drag hook
End is whole L-shaped, and the attraction pipeline is set to the side at the drag hook end and the drag hook end is followed to go deep into the bone of side temporal bone
Slot.
