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

New craniotomy drill drill bit structure
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.
Brief description of the drawings
Fig. 1 is the schematic diagram of the present invention.
Wherein:1- connecting shafts, 2- drill bits, 3- line shafts, 4- retainer rings, 5- energization tracks, 6- electromagnetism expansion links, 7- electromagnetism Telescopic block, 8- buffer stoppers, 9- control lines, 10- starts pedal.
Embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, the embodiment It is only used for explaining the present invention, is not intended to limit the scope of the present invention..
As shown in figure 1, the present embodiment provides a kind of new craniotomy drill drill bit structure, include connecting shaft 1 and drill bit 2, institute State drill bit 2 to be connected in connecting shaft 1, line shaft 3 is provided with connecting shaft 1 offer power is provided with drill bit 2;The drill bit 2 exists Be provided with the retainer ring 4 of irony in the part of connecting shaft 1, part of the drill bit 2 in connecting shaft 1 is made of iron, in connecting shaft 1 on Under be provided at both ends with energization track 5, energization track 5 be fixed with two be powered after can produce the electromagnetism expansion link 6 of magnetic, two Electromagnetism expansion link 6 is arranged on the both sides of retainer ring 4.Be located on the energization track 5 between two electromagnetism expansion links 6 be additionally provided with it is logical Electricity can produce the electromagnetism telescopic block 7 of magnetic, and electromagnetism telescopic block 7 is located at the surface of retainer ring 4.The head of electromagnetism expansion link 6 It is provided with buffer stopper 8.The energization track 5 can intermittence be powered, can also continuously be powered.The energization track 5 is connected with control Line 9 processed, control line 9 is connected with startup pedal 10.
Drill bit 2 and line shaft 3 are connected by setting connecting shaft 1, sets electromagnetism expansion link 6 to be powered in connecting shaft 1 and produces Magnetisation is contacted with drill bit 2 carrys out stop;And retainer ring is set on drill bit 2, and 4 pass through the energizing magnetic of electromagnetism telescopic block 6 Contacted with retainer ring 4 and also carry out stop;And two electromagnetism expansion links 6 and electromagnetism telescopic block 7 are arranged on energization track, so 7 position-adjustables of electromagnetism expansion link 6 and electromagnetism telescopic block, two electromagnetism expansion links 6 can clamp retainer ring 4 to be stretched with electromagnetism Block 7, which coordinates, carries out stop;And the energization for the track 5 that is powered is controlled by starting pedal 10, thus can be in emergency Under by foot control system come stop, hand only need to control to open, it is to avoid confusion.
