Abstract
The present invention provides a kind of new craniotomy drill drill bit structure, and drill bit and line shaft are connected by setting connecting shaft, sets electromagnetism expansion link energizing magnetic to carry out stop with bit contact in connecting shaft；And retainer ring is set on drill bit, is contacted by electromagnetism telescopic block energizing magnetic with retainer ring and also carries out stop；And two electromagnetism expansion links and electromagnetism telescopic block are arranged on energization track, the position-adjustable of such electromagnetism expansion link and electromagnetism telescopic block, two electromagnetism expansion links, which can clamp retainer ring with electromagnetism telescopic block to coordinate, carries out stop；, thus can be in case of emergency by foot control system come stop and the energization for the track that is powered is controlled by starting pedal, hand only need to control to open, it is to avoid confusion；The present invention is simple in construction easy to operate, can aid in split cranium drilling row stop and locking well on the basis of original stop, it is adaptable in operation of opening cranium.
Description
Technical field
The present invention relates to medical apparatus field, more particularly to a kind of new craniotomy drill drill bit structure.
Background technology
My company mainly produces some medical apparatus, mainly there is the apparatus such as craniotomy drill, chest bone saw, pendulum brill, and craniotomy drill is main
For in operation of opening cranium, operation of opening cranium must to need very precisely, and control is very well, not so can be caused seriously for the life of patient
Influence, therefore particularly significant for the stop locking of craniotomy drill, traditional is to carry out stop, sometimes decelerator using decelerator
It is slow will not stop quickly, and stop immediately must be needed in performing the operation, therefore the application devises one kind does not influence original
Operation structure.
The content of the invention
The present invention provides a kind of new craniotomy drill drill bit structure, by being provided with electromagnetism expansion link and electromagnetism in connecting shaft
Telescopic block energizing magnetic is contacted so as to realize the function of stop and locking so as to extend the part with drill bit in connecting shaft,
Solve produced problem in background technology.
To solve the above problems, the present invention provides a kind of new craniotomy drill drill bit structure, include connecting shaft and drill bit, institute
State drill bit to be connected in connecting shaft, line shaft is provided with connecting shaft offer power is provided with drill bit；The drill bit is in connecting shaft
Part in be provided with the retainer ring of irony, part of the drill bit in connecting shaft is made of iron, and upper and lower ends are set in connecting shaft
The electromagnetism expansion link of magnetic can be produced after two energizations are fixed with energization track, energization track by having, and two electromagnetism expansion links are set
Put in retainer ring both sides.
Further improvement is that：Being additionally provided with energization between two electromagnetism expansion links on the energization track can produce
The electromagnetism telescopic block of magnetic, electromagnetism telescopic block is located at the surface of retainer ring.
Further improvement is that：The flexible club head of the electromagnetism is provided with buffer stopper.
Further improvement is that：The energization track can intermittence be powered, can also continuously be powered.
Further improvement is that：The energization track is connected with control line, and control line is connected with startup pedal.
Beneficial effects of the present invention：The present invention connects drill bit and line shaft by setting connecting shaft, is set in connecting shaft
Put electromagnetism expansion link energizing magnetic and carry out stop with bit contact；And retainer ring is set on drill bit, it is flexible by electromagnetism
Block energizing magnetic is contacted with retainer ring also carries out stop；And two electromagnetism expansion links and electromagnetism telescopic block are arranged on energization
On track, the position-adjustable of such electromagnetism expansion link and electromagnetism telescopic block, two electromagnetism expansion links retainer ring can be clamped with
Electromagnetism telescopic block, which coordinates, carries out stop；, thus can be urgent and the energization for the track that is powered is controlled by starting pedal
In the case of by foot control system come stop, hand only need to control to open, it is to avoid confusion；The present invention is simple in construction easy to operate, original
Stop on the basis of can aid in split cranium drilling row stop and locking well, it is adaptable in operation of opening cranium.
