Description
Technical field
This utility model relates to neurosurgical operation instrument technical field, is specially a kind of neurosurgical doctor with protective effect and uses brill bone object tool.
Background technology
When bone surgery, behind guider location, squeeze into guide pin, then utilize core drill to make tibial tunnel along guide pin, but this mode has problems: tibial tunnel internal orifice is positioned at the tibial plateau back lower place, and neighbour important blood vessels is neural.Making guide pin and core drill in tibial tunnel process must utilize electric drill to pierce with feel; pierced deep, guide pin moves with core drill, core drill pierced deep injured blood vessel nerve and is likely to; therefore, it is proposed that a kind of neurosurgical doctor with protective effect uses and bores bone object tool.
Utility model content
The purpose of this utility model is in that providing a kind of neurosurgical doctor with protective effect to use bores bone object tool, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme: a kind of neurosurgical doctor with protective effect uses and bores bone object tool, including drill body, one end of drill body is connected to guide pin by guide pin holder, guide pin holder is set with sleeve body, the surface of sleeve body is set with frame body, the surface of sleeve body is provided with graduation mark, frame body is by large circle, small circle ring, connecting rod, the collar and groove composition, connected by connecting rod between large circle and small circle ring, one end of small circle ring is provided with the collar, the surface of this collar offers groove, the surface of sleeve body offers groove, and the surface of the collar is provided with fastening bolt.
Preferably, the surface of the described collar offers through hole, and fastening bolt is connected through this through hole with groove.
Preferably, described small circle ring and the collar are tightly sleeved the surface at sleeve body.
Preferably, described groove is corresponding with graduation mark.
Compared with prior art, the beneficial effects of the utility model are: this has the neurosurgical doctor of protective effect with boring bone object tool, simple in construction, easy to use, first pass through sleeve body and can limit length when guide pin pierces, thus can ignore osseous tunnel length, accurately control guide pin and penetrate cortex on rear side of tibia, can also by frame body when guide pin pierces, restriction guide pin moves to depths with core drill, accurately control core drill and drill through tunnel, groove and graduation mark with the use of, observation can be easy to by user of service and pierce the degree of depth, fixing effect is played again with groove and fastening bolt.
Accompanying drawing explanation
Fig. 1 is that this utility model structural diagrams is intended to；
Fig. 2 is this utility model structural frames support body schematic diagram.
In figure: 1 drill body, 2 guide pin holders, 3 guide pins, 4 sleeve bodies, 5 frame bodies, 51 large circles, 52 small circle rings, 53 connecting rods, 54 collars, 55 grooves, 6 grooves, 7 graduation marks, 8 fastening bolts.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
nullRefer to Fig. 1-2，This utility model provides a kind of technical scheme: a kind of neurosurgical doctor with protective effect uses and bores bone object tool，Including drill body 1，One end of drill body 1 is connected to guide pin 3 by guide pin holder 2，Guide pin holder 2 is set with sleeve body 4，Sleeve body 4 can limit length when guide pin 3 pierces，Thus can ignore osseous tunnel length，Accurately control guide pin and penetrate cortex on rear side of tibia，The surface of sleeve body 4 is set with frame body 5，The surface of sleeve body 4 is provided with graduation mark 7，Frame body 5 is by large circle 51、Small circle ring 52、Connecting rod 53、The collar 54 and groove 55 form，Small circle ring 52 and the collar 54 are tightly sleeved on the surface of sleeve body 4，Large circle 51、Small circle ring 52 and the collar 54 with the use of，Guide pin 3 can be played in use the effect of fastening，Guide pin 3 will not be made to deviate，Connected by connecting rod 53 between large circle 51 and small circle ring 52，One end of small circle ring 52 is provided with the collar 54，The surface of this collar 54 offers groove 55，Groove 55 is corresponding with graduation mark 7，Frame body 5 can also be passed through when guide pin 3 pierces，Restriction guide pin 3 moves to depths with core drill，Accurately control core drill and drill through tunnel，Groove 55 and graduation mark 7 with the use of，Observation can be easy to by user of service and pierce the degree of depth，Fixing effect is played again with groove 6 and fastening bolt 8，Groove 6 and fastening bolt 8 can also play the effect of restriction when guide pin 3 works simultaneously，Accurately control to pierce the degree of depth，The surface of sleeve body 4 offers groove 6，And the surface of the collar 54 is provided with fastening bolt 8，The surface of the collar 54 offers through hole，And fastening bolt 8 is connected through this through hole with groove 6.
