Gear 61, output shaft 3 and drill bit 5, owing to being arranged between gear 61 and output shaft 3
The effect of one-way clutch 63, travelling nut 65 the most back and forth, make output shaft 3
Rotate around same direction, thus carry out boring cranium operation, in this programme, the power of skull drilling device
Source and the hands of operator, it is not necessary to connect external power supply, it is simple to operation, low cost,
And this simple in construction, easily polluter is controlled, on the other hand, boring direction
Identical with the direction of the active force of operator, when there is not boring, active force causes boring position
Put offset, drill bit 5 swing guide causes injury the problems such as mouth is bigger;Utilize people the sensitiveest
Position forefinger and middle finger, as the power resources of this skull drilling device, not only make this skull drilling device
Easily controllable, and can be with the operation of upper frequency, the drilling efficiency making this skull drilling device is big
Big raising, alleviates the misery of patient, shortens the time of operation;In this programme, adopt
With tooth fan 62 and the drive mechanism of gear 61 engagement, on the one hand, higher gear ratio can
To improve the rotary speed of drill bit 5, on the other hand, tooth fan 62 can reduce this skull drilling device
Overall volume.
Specific embodiment described herein is only to present invention spirit theory for example
