Description
Technical field:
This utility model relates to medical apparatus and instruments, and particularly a kind of brain outer operation is used hand drill.
Background technology:
Usually use electric drill in the operation of opening cranium of department of cerebral surgery, present electric drill does not have spacing or detent mechanism more, and the boring depth is difficult for grasping, in case it is darker to pierce the degree of depth, is prone to cause brain injury.In addition, the electric drill drilling speed is high, drill bit quick heating, near the phenomenon of the tissue boring of often burning.In view of this technical problem, it is a kind of simple in structure, easy to use to press for appearance, and a kind of brain outer operation that is easy to the keyhole degree of depth and drilling speed is used hand drill.
Summary of the invention:
The purpose of this utility model is to overcome the shortcoming that exists in the prior art, provides a kind of simple in structure, easy to use, and a kind of brain outer operation that is easy to the keyhole degree of depth and drilling speed is used hand drill.
To achieve these goals, this utility model provides a kind of brain outer operation to use hand drill, comprises serrated knife drill bit and screw rod; Wherein, said screw rod bottom is provided with gap, plugs together between serrated knife drill bit and the said gap to be connected; Said screw rod is provided with the serrated knife lock, and said screw rod top further is provided with rocking arm, and said rocking arm is the rectangle frame of an end opening; Further be provided with axle sleeve on the said rocking arm, said axle sleeve is provided with position fixing handle, and axle is connected between said position fixing handle and the said axle sleeve.
Be fixedly connected between said rocking arm and the said screw rod, be fixedly connected between said rocking arm and the said axle sleeve, said rocking arm is provided with handle, and said handle and said rocking arm are one-body molded during fabrication.
Said rocking arm can be that basic point is rotated with said position fixing handle, and said serrated knife lock is used to tighten up said gap and then clamping serrated knife drill bit.
Said position fixing handle be positioned at said screw rod directly over, said position fixing handle and said screw rod are located along the same line.
Be fixedly connected between said serrated knife lock and the said screw rod.
The advantage of this utility model is: simple in structure, easy to use, be easy to the keyhole degree of depth and drilling speed.Be specially:
The mode that this utility model adopts rocking arm to be fixedly connected with screw rod, the screw rod bottom is provided with gap, and gap is plugged and connected with the serrated knife drill bit; Screw rod is provided with the serrated knife lock; The serrated knife lock tightens up gap and then clamps the serrated knife drill bit in the gap through screw thread, and rocking arm top is fixedly connected with axle sleeve, and axle connects position fixing handle on the axle sleeve; Position fixing handle be positioned at said screw rod directly over, position fixing handle and screw rod are located along the same line.During use, press position fixing handle, the rotation rocking arm gets final product, and the serrated knife drill bit is along with the rotation precession, and the drilling speed and the degree of depth can be controlled through the drilling speed of rocking arm, speed-controllable, near the tissue boring of needn't burning.
