Abstract
The invention provides a novel craniotomy drill bit structure, wherein a connecting shaft is arranged to connect a bit and a power shaft; electromagnetic telescopic rods are arranged in the connecting shaft and are electrified to generate magnetism to contact with the bit for stopping the bit; a fixed ring is arranged on the bit; electromagnetic telescopic blocks are electrified to contact the fixed ring for stopping the fixed ring; the two electromagnetic telescopic rods and the electromagnetic telescopic blocks are arranged on an electrified track, so that the positions of the electromagnetic telescopic rods and the electromagnetic telescopic blocks are adjustable; the two electromagnetic telescopic rods can clamp the fixed ring and stop the fixed ring in a manner of coordinating with the electromagnetic telescopic blocks; a starting pedal controls the electrifying of the electrified track, so that stopping can be performed through a foot in emergency; starting is only controlled by a hand, and chaos is avoided. The novel craniotomy drill bit structure disclosed by the invention is simple in structure and easy to operate; a craniotomy drill can be stopped and locked well on a base of the original stopping, and the novel craniotomy drill bit structure is suitable for craniotomy.
Description
Technical field
The present invention relates to medical apparatus field, particularly relate to a kind of novel drill for craniotomy drill bit structure.
Background technology
My company mainly produces some medical apparatus, mainly contain the apparatus such as drill for craniotomy, chest bone saw, pendulum brill, drill for craniotomy is mainly used in operation of opening cranium, operation of opening cranium must need very accurate, control very well, not so the life for patient can cause serious impact, therefore the stop locking for drill for craniotomy is very important, traditional is adopt decelerator to carry out stop, sometimes decelerator is slow can not stop quickly, and stop immediately must be needed in operation, therefore the application devises a kind of structure not affecting original operation.
Summary of the invention
The invention provides a kind of novel drill for craniotomy drill bit structure, by being provided with electromagnetism expansion link and electromagnetism telescopic block energizing magnetic thus the part contact extended with drill bit in connecting axle thus realize the function of stop and locking in connecting axle, solve produced problem in background technology.
For solving the problem, the invention provides a kind of novel drill for craniotomy drill bit structure, include connecting axle and drill bit, described drill bit is connected in connecting axle, is provided with line shaft and is connected with drill bit and provides power in connecting axle; Described drill bit is provided with the retainer ring of irony in the part of connecting axle, the part of drill bit in connecting axle is made of iron, in connecting axle, two ends are provided with energising track up and down, can produce the electromagnetism expansion link of magnetic after energising track being fixed with two energisings, two electromagnetism expansion links are arranged on retainer ring both sides.
Further improvement is: described energising track is also provided with between two electromagnetism expansion links the electromagnetism telescopic block that energising can produce magnetic, electromagnetism telescopic block is positioned at directly over retainer ring.
Further improvement is: described electromagnetism expansion link head is provided with buffer stopper.
Further improvement is: described energising track can intermittence be energized, and also can be energized continuously.
Further improvement is: described energising track is connected with control line, and control line is connected with startup pedal.
Beneficial effect of the present invention: the present invention connects drill bit and line shaft by arranging connecting axle, arranges electromagnetism expansion link energizing magnetic in connecting axle and bit contact carrys out stop; And retainer ring is set on drill bit, is contacted with retainer ring by electromagnetism telescopic block energizing magnetic and also carry out stop; And two electromagnetism expansion links and electromagnetism telescopic block are arranged on energising track, the position-adjustable of such electromagnetism expansion link and electromagnetism telescopic block, retainer ring can be clamped to coordinate with electromagnetism telescopic block and carry out stop by two electromagnetism expansion links; And the energising of the track that is energized controls by starting pedal, so just in case of emergency can carry out stop by foot control system, and hands only need control to open, and avoids confusion; Structure of the present invention is simple to operation, original stop basis can be assisted well split cranium and creep into row stop and locking, is applicable in operation of opening cranium.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Wherein: 1-connecting axle, 2-drill bit, 3-line shaft, 4-retainer ring, 5-is energized track, and 6-electromagnetism expansion link, 7-electromagnetism telescopic block, 8-buffer stopper, 9-control line, 10-starts pedal.
Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, and this embodiment only for explaining the present invention, does not form limiting the scope of the present invention.
As shown in Figure 1, the present embodiment provides a kind of novel drill for craniotomy drill bit structure, includes connecting axle 1 and drill bit 2, and described drill bit 2 is connected in connecting axle 1, is provided with line shaft 3 and is connected with drill bit 2 and provides power in connecting axle 1; Described drill bit 2 is provided with the retainer ring 4 of irony in the part of connecting axle 1, the part of drill bit 2 in connecting axle 1 is made of iron, in connecting axle 1, two ends are provided with energising track 5 up and down, electromagnetism expansion link 6, two electromagnetism expansion links 6 that can produce magnetic after energising track 5 being fixed with two energisings are arranged on retainer ring 4 both sides.Described energising track 5 is also provided with between two electromagnetism expansion links 6 the electromagnetism telescopic block 7 that energising can produce magnetic, electromagnetism telescopic block 7 is positioned at directly over retainer ring 4.Described electromagnetism expansion link 6 head is provided with buffer stopper 8.Described energising track 5 can intermittence be energized, and also can be energized continuously.Described energising track 5 is connected with control line 9, and control line 9 is connected with and starts pedal 10.
Connecting drill bit 2 and line shaft 3 by arranging connecting axle 1, electromagnetism expansion link 6 energizing magnetic being set in connecting axle 1 and contacting stop with drill bit 2; And arrange retainer ring on drill bit 2,4 to be contacted with retainer ring 4 by electromagnetism telescopic block 6 energizing magnetic and also carry out stop; And two electromagnetism expansion links 6 and electromagnetism telescopic block 7 are arranged on energising track, 7 position-adjustable of such electromagnetism expansion link 6 and electromagnetism telescopic block, retainer ring 4 can be clamped to coordinate with electromagnetism telescopic block 7 and carry out stop by two electromagnetism expansion links 6; And the energising of the track 5 that is energized controls by starting pedal 10, so just in case of emergency can carry out stop by foot control system, and hands only need control to open, and avoids confusion.
The present embodiment structure is simple to operation, original stop basis can be assisted well split cranium and creep into row stop and locking, is applicable in operation of opening cranium.
