Description
Technical field
The present invention relates to the field of medical instrument technology, more particularly, to a kind of fossa cranii media retractor and its working method.
Background technique
Fossa cranii media operation is from middle cranial fossa approach to spikes and internal auditory meatus excision vestibular nerve treats dizziness, processing facial nerve
Indication, method and the complication of the operations such as labyrinthine segment lesion and excision internal auditory meatus tumour.Operation method: patient lies on the back general anesthesia,
Making one along crus helicis front steering temples on from before tragus is slightly in " 7 " notched cut, separates temporalis and temporal fascia, and electric drill cuts 3*
4cm2Meninx is inwardly separated, and is pulled open meninx and temporal lobe with traditional retractor by rectangular temporal bone valve.
Traditional fossa cranii media retractor only replaces pawl mostly similar to surgical scissors structure at the blade edge position of surgical scissors
Hook structure, and fixed between hand-held part by toothing.Traditional retractor of this structure is only capable of pulling open temporal lobe
Relatively narrow space, and the distance that temporal lobe pulls open cannot critically be controlled by the positioning of toothing, i.e., it can not accurately control
Surgical procedure space processed；Simultaneously when needing further adjustment surgical procedure space, traditional retractor does not have stabilization function, and
The opening and closing of toothing, which are easy to produce, all to be understood, hand shaking when along with patient's operation can impact operation.
Summary of the invention
Present invention solves the technical problem that be traditional fossa cranii media retractor structure can not accurately adjust surgical procedure sky
