Further, a connecting piece is arranged between the limiting plate and the ear plate, and the limiting plate and the ear plate are detachably connected through the connecting piece. Through such setting, be convenient for the fixed and separation of limiting plate and otic placode through the operation connecting piece.

Further, the connecting piece adopts the screw rod, be equipped with first screw hole on the limiting plate, be provided with the second screw hole on the otic placode, the screw rod passes first screw hole with the second screw hole is connected. Through such setting, simple structure connects reliably, can make the screw rod keep somewhere on the limiting plate.

Further, the connecting piece adopts a fixing clamp structure. Through the arrangement, the ear plate and the limiting plate are clamped through the fixing clamp, so that the ear plate and the limiting plate are fixed, and the ear plate and the limiting plate can be separated by loosening the fixing clamp.

Further, a fixing belt is arranged on the sleeve. With this arrangement, the retention of the cannula is facilitated.
