Description
Technical field
This utility model relates to technical field of medical instruments, refers to a kind of bone drill for spinal operation especially.
Background technology
When carrying out spinal column endoscopic surgery; especially when intervertebral spinal fusion road enters to perform the operation; need by milled portion articular process; thus be positioned intraspinal tube, and grinding articular process needs to produce an opening with surgical drill or milling cutter at articular facets, to carry out the foundation of passage; wherein; these surgical drills all must be advanced and very meticulous, and with safeguard protection, avoid damage dural sac and nerve root.
But, there is following problem in existing surgical drill self or use procedure:
1, the diameter of existing bone drill group is excessive, and the wound caused when operation uses is relatively large;
2, existing bone drill cannot be accomplished to stretch into value location in use, so just needs constantly to have an X-rayed, not in place or drill-through to avoid bone drill to bore, and which substantially increases the radiation of patient and doctor;
3, in existing bone drill, minimum bone drill must use diameter to guide for 0.7mm seal wire; easy generation seal wire fracture and drill bit protection part are burst apart; operation process not only can be caused to go wrong; also nerve root can be caused to there is the possibility of damage; if seal wire ruptures; open surgery must be carried out fracture seal wire could be taken out, thus potential great risk is stayed to patient.
Utility model content
The utility model proposes a kind of bone drill, solve the problem described in background technology.
The technical solution of the utility model is achieved in that
A kind of bone drill; comprise: the localizer used for Path Setup and the protection head, drill bit, drilling rod, the drillstock that connect successively; localizer be fixed on carry out surgical spinal column operation path on; be characterized in; protection head, drill bit, drilling rod and drillstock is one-body molded; drilling rod is provided with graduated scale, and the value of drilling rod external diameter is 3.8 ~ 8.8mm.
As further technical scheme, drilling rod external diameter is specially 3.8mm, 5.8mm, 6.8mm, 7.8mm, 8.8mm, and the internal diameter of above-mentioned five kinds of external diameter drilling rods is respectively: 1.1mm, 1.6mm, 1.6mm, 1.6mm, 1.6mm.
As further technical scheme, bit face is provided with wear-resistant coating.
The beneficial effects of the utility model are:
1, drill body increases scale, thus doctor can be made according to scale to understand the degree of depth pierced in use, and then can reduce the number of times of perspective, reduces patient and doctor's radiation hazradial bundle.
2, drill body and drillstock adopt one-shot forming technique, abandon welding procedure, thus expand on the internal diameter of bone drill, thus more durable seal wire can be adopted, what avoid the fracture of seal wire and bone drill front end collapses limit, avoids seal wire fracture and cannot take out the risk with injured nerve root to body.
3, the external diameter of bone drill approach clinic demand more, has carried out suitable reducing, thus has avoided larger wound.
4, in the process removing skeleton, add and can carry out pinpoint localizer, thus ensure that the stability in bone drill use procedure, be unlikely to offset.
5, add wear-resistant coating at the cutting part of drill bit, thus the use of drill bit can be extended.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
Fig. 1 is this utility model structural representation;
Fig. 2 is locator structure schematic diagram in this utility model.
In figure: 1, drill bit; 11, wear-resistant coating; 2, drilling rod; 21, graduated scale; 3, drillstock; 4, localizer; 5, head is protected.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, be clearly and completely described the technical scheme in this utility model embodiment, obviously, described embodiment is only this utility model part embodiment, instead of whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of this utility model protection.
As shown in Fig. 1 ~ Fig. 2, a kind of bone drill that the utility model proposes, comprising:
The localizer 4 used for Path Setup and the protection that connects successively 5, drill bit 1, outer bar 2, drillstock 3; localizer 4 be fixed on carry out surgical spinal column operation path on; be characterized in; drill bit 1, outer bar 2 and drillstock 3 are one-body molded; outer bar 2 is provided with graduated scale 21, and the value of outer bar 2 external diameter is 3.8 ~ 8.8mm.
Protection 5, drill bit 1, outer bar 2, drillstock 3 connect successively; wherein; protection 5, drill bit 1, outer bar 2 are one-body molded with drillstock 3; thus can make the outer bar 2 internal diameter span of bone drill can be larger; thus more durable seal wire can be adopted; what avoid the fracture of seal wire and bone drill front end collapses limit, avoids seal wire fracture and cannot take out the risk with injured nerve root to body.In addition, this utility model China and foreign countries bar 2 is provided with graduated scale 21, thus drill bit 1 can be viewed by graduated scale 21 and bore the bone degree of depth, thus the number of times of perspective can be reduced, reduce patient and doctor's radiation hazradial bundle.Moreover outer bar 2 external diameter is reduced, thus approach clinic demand more, thus avoid larger wound.
In the process removing skeleton; manual, experiential operating entirely with doctor are difficult to ensure the stability in bone drill use procedure; in this utility model; added one for remove skeleton use, can carry out pinpoint localizer 4 with the use of; and ensure that the stability in bone drill use procedure; coordinate the neuroprotective head 5 of drill bit 1 to position, be unlikely to offset.
As further technical scheme, outer bar 2 external diameter is specially 3.8mm, 5.8mm, 6.8mm, 7.8mm, 8.8mm, and the internal diameter of the outer bar 2 of above-mentioned five kinds of external diameters is respectively: 1.1mm, 1.6mm, 1.6mm, 1.6mm, 1.6mm.
In bone drill use procedure; need to coordinate seal wire to guide; in existing bone drill, minimum bone drill internal diameter is too small; the maximum diameter that can only use guides for 0.7mm seal wire; so easy generation seal wire fracture and drill bit 1 protection part are burst apart; in this utility model; one-shot forming technique is adopted by drill body and drillstock 3; minimum outer diameter is made to be that outer bar 2 internal diameter of 3.8mm also can expand to 1.1mm; thus more durable seal wire can be adopted; what avoid the fracture of seal wire and bone drill front end collapses limit, avoids seal wire fracture and cannot take out the risk with injured nerve root to body.
As further technical scheme, drill bit 1 surface is provided with wear-resistant coating 11.
Operating theater instruments acts on skeleton, very large loss can be produced to apparatus, especially bone drill, the wearing and tearing of its drill bit 1 position are very serious, and then the problem that its service life can be caused not high, in this utility model, drill bit 1 surface has added wear-resistant coating 11, thus can extend the service life of drill bit 1.
These are only preferred embodiment of the present utility model, not in order to limit this utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
