With postoperative cleaning.
Further, the shield is half bell shape, has a diameter larger than drill bit, when shield is mounted on main part,
It is slightly above drill bit bottom position at the distal opening of shield.Drill bit and flap can perfectly be separated by by the shield of half bell shape
From to protecting flap, while the production of bone slot is not influenced again.
Further, the transmission ratio of the driving gear and driven gear is set as 1:1.
Further, the driving gear and driven gear are straight bevel gear.
Gear drive is steady, and transmission ratio is accurate, and reliable operation, high-efficient, the service life is long.The revolving speed for providing the electric drill of power can
Adjust and be able to satisfy operation needs, and 1:1 transmission ratio can ensure that the power output of electric drill is undamped, and revolving speed and torque are kept not
Become.
Further, the axis of the shaft of the driving gear and driven gear is mutually perpendicular to.This power transmits angle
Change meet bone slot open up demand.
The effect reached：One, artificial cochlea's surgical implant bone slot target drill provided by the utility model, the bone opened up
Slot size is accurate, can effectively reduce postoperative cochlear implantation prosthesis displacement risk, to reduce displacement bring postoperative complication.Two,
Drill bit size is mutually fitted with cochlear implantation prosthesis size, and power direction of transfer is changeable, it is possible to reduce the time calibrated when polishing, greatly
It is big to shorten operation duration.Three, shield can protect flap injury-free, and the effective flap that reduces is because of skin caused by surgical injury
The complication such as valve necrosis.
