Description
Technical field
This utility model relates to neurosurgery apparatus field, especially a kind of cranial drill.
Background technology
Need to enclose bore bone hole at bone window in neurosurgery repairing operation; so that fixing artificial skull; in order to prevent bit breakage cerebral tissue; generally that brain spatula is placed between skull and cerebral dura mater to protect cerebral tissue; although this way plays certain protective action, because drill bit is separated with brain spatula, under the impact of drill bit; brain spatula moves compressing cerebral tissue, causes brain tissue impairment.Often need to hole on skull in cerebral surgery operation, but existing cranial drill is difficult to abut on the skull of patient, very unstable when thus holing, so not easily manipulate in clinical cerebral surgery operation, often need by cranial drill perforate on skull, the mostly manual operation of current cranial drill, procedure efficiency is low, and doctor's labor intensity is large.In addition, often need when adopting current cranial drill to hole first to position by other apparatuses, operate cumbersome, make troubles to medical work.
Utility model content
This utility model aims to provide a kind of cranial drill.
For achieving the above object, this utility model provides following technical scheme: a kind of cranial drill, comprises drilling rod, guide pipe, motor shaft, mair motor, housing, slide, riffled tube, screw rod, feeding motor, controller, gun-type hands handle, gauge tap, switching button, guide rail, cambered surface, protective plate, the front end of described housing is provided with guide pipe, tail end is provided with gun-type handle, cambered surface is provided with outside described guide pipe, guide rail is provided with along its length in described housing, described guide rail is provided with slide, mair motor is fixed with on front side of described slide, rear side is provided with the riffled tube of hollow, described mair motor installed in front has drilling rod, described drilling rod is positioned at guide pipe and is driven by motor shaft, and described housing rear end is fixed with a feeding motor, and described feeding motor front end is connected with a screw rod, described screw rod and riffled tube pass through threaded engagement, described housing tail end is provided with controller, and the downside of described housing is provided with trigger-type gauge tap, is provided with switching button on the upside of trigger-type gauge tap simultaneously.
Preferably, described switching button is for changing turning to of feeding motor.
Preferably, described drilling rod is in protective plate.
Compared with prior art, the beneficial effects of the utility model are: be communicated with power supply by controller of the present utility model by trigger-type gauge tap, feeding motor drives the parts reach be positioned on front side of it, drilling rod is driven by mair motor simultaneously, move forward while rotate, when namely piercing in patient's sclerotin after stretching out guide pipe, realize sphenotresia.Its structure is simple, and energy consumption is low, is convenient to grip, and without the need to positioning by other devices when holing initial, brings conveniently to medical work.Be provided with cambered surface, can well abut on the skull of patient, thus good stability, be convenient to manipulation, drill bit and protective plate be threaded connection into a single integrated structure, even if be subject to the impact of drill bit, protective plate also can not produce movement, effectively protects cerebral tissue.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
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.
Refer to Fig. 1, in this utility model embodiment, a kind of cranial drill, comprises drilling rod 1, guide pipe 2, motor shaft 3, mair motor 4, housing 5, slide 6, riffled tube 7, screw rod 8, feeding motor 9, controller 10, gun-type handle 11, gauge tap 12, switching button 13, guide rail 14, cambered surface 15, protective plate 16, the front end of described housing 5 is provided with guide pipe 2, tail end is provided with gun-type handle 11, described drilling rod 1 is in protective plate 16, cambered surface 15 is provided with outside described guide pipe 2, guide rail 14 is provided with along its length in described housing 5, described guide rail 14 is provided with slide 6, mair motor 4 is fixed with on front side of described slide 6, rear side is provided with the riffled tube 7 of hollow, and described mair motor 4 installed in front has drilling rod 1, and described drilling rod 1 is positioned at guide pipe 2 and is driven by motor shaft 3, described housing 5 rear end is fixed with a feeding motor 9, described feeding motor 9 front end is connected with a screw rod 8, and described screw rod 8 and riffled tube 7 are by threaded engagement, and described housing 5 tail end is provided with controller 10, the downside of described housing 5 is provided with trigger-type gauge tap 12, is provided with switching button 13 on the upside of trigger-type gauge tap 12 simultaneously.
Preferably, described switching button 13 is for changing turning to of feeding motor 9.
Operation principle of the present utility model is: during use, on the skull that the lower surface of cambered surface 15 abuts in by medical personnel, the lower face of protective plate is inserted between skull and cerebral dura mater, cocking formula gauge tap 12, feeding motor 9 lead-screw 8 slides at guide rail 14, and then promote slide 6 forward, under the effect of mair motor 4, drive motor axle 3 rotates, thus it is dynamic to drive drilling rod 1 to bore.
