Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of orthopaedics target drill.
Background technology
Internal fixtion blade plate and lock screw system thereof are because of its distinctive biomechanical advantage, the high praise enjoying AO to organize and apply to orthopaedic trauma more and more, related complication after following its a large amount of abuse in addition and shortcoming, wherein major part and lock screw are taken out difficult relevant, include " cold welding " that screw socket damage, screw stripped thread and pinning threading dislocations cause etc.It is compare stubborn problem in bone surgery that lock screw takes out difficulty; Existing orthopaedics drill bit, without the function removing chip, can produce amount of heat when cutting off blade plate simultaneously, bringing very large misery to patient, also gives in the operation of medical worker and brings very large inconvenience.
Utility model content
For above-mentioned problems of the prior art, this utility model aims to provide a kind ofly can remove chip and the orthopaedics target drill preventing in use temperature too high in time.
To achieve these goals, this utility model takes following technical scheme:
A kind of orthopaedics target drill, comprise Hollow trepanning drilling machine, cannulated sleeve, center-pole and cutter head, described cannulated sleeve is located in Hollow trepanning drilling machine, and is fixedly connected with the afterbody of Hollow trepanning drilling machine, described cannulated sleeve and Hollow trepanning drilling machine concentric.
Described cutter head is the barrel-like structure of front opening, and the blade place of described cutter head is provided with some cutters tooth, and described cutter tooth can strengthen the cutting power of cutter head, improves cutting effect.
Described center-pole is located in cannulated sleeve and also freely can rotates in cannulated sleeve, spring is provided with in described cannulated sleeve, described spring is positioned at the afterbody of center-pole, the front end of described center-pole is stretched out in Hollow trepanning drilling machine, described center-pole front end is six prisms, and the afterbody of described Hollow trepanning drilling machine is provided with coupling bar.
It is characterized in that, described Hollow trepanning drilling machine is provided with exhaust tube, and described exhaust tube front end communicates with the cavity of cutter head, and described exhaust tube rear end is provided with scrap collecting bag, and described scrap collecting bag is used for collecting the chip produced in cutting process.Described exhaust tube is provided with air pump.
Further, the inside of described six prisms is provided with Magnet, and screw can be held by magnetic force by Magnet in use, prevents toner screw or skidding.
Further, described coupling bar is prism.
The beneficial effects of the utility model are: can cleared of debris in time, and play the effect of convulsion cooling, and it is too high to prevent from boring temperature in cutover hone lamella process; Well screw can be held by magnetic force by Magnet, prevent from coming off or skidding.

Detailed description of the invention
For the ease of understanding, below in conjunction with accompanying drawing, by embodiment, technical solutions of the utility model are further described in detail:
As depicted in figs. 1 and 2, a kind of orthopaedics target drill, comprises Hollow trepanning drilling machine 1, cannulated sleeve 2, center-pole 3 and cutter head 4.
Cannulated sleeve 2 is located in Hollow trepanning drilling machine 1, and is fixedly connected with the afterbody of Hollow trepanning drilling machine 1, cannulated sleeve 2 and Hollow trepanning drilling machine 1 concentric.
Cutter head 4 is the barrel-like structure of front opening, and the blade place of cutter head 4 is provided with some cutters tooth 9, and cutter tooth 9 can strengthen the cutting power of cutter head 4, improves cutting effect.
Center-pole 3 is located in cannulated sleeve 2 and also freely can rotates in cannulated sleeve 2, spring 12 is provided with in cannulated sleeve 2, spring 12 is positioned at the afterbody of center-pole 3, the front end of center-pole 3 is stretched out in Hollow trepanning drilling machine 1, center-pole 3 front end is six prisms 5, the afterbody of Hollow trepanning drilling machine 1 has coupling bar 11, and described coupling bar 11 is prism.
The rear portion of Hollow trepanning drilling machine 1 is provided with exhaust tube 8, and exhaust tube 8 communicates with the cavity of cutter head 4 through the rear sidewall of Hollow trepanning drilling machine 1, anterior sidewall and cutter head 4; Exhaust tube 8 is provided with air pump 7, the rear end of exhaust tube 8 is provided with scrap collecting bag 6, and scrap collecting bag 6 is used for collecting the chip produced in cutting process.
The inside of six prisms 5 is provided with Magnet 10, and screw can be held by magnetic force by Magnet 10 in use, prevents toner screw or skidding.
During use, by the coupling bar 11 of Hollow trepanning drilling machine 1 afterbody and electric device, as electric drill or handheld electrical machinery connect, six prisms 5 of center-pole 3 head end are withstood in the inner hexagonal hole of the lock screw head of a nail of internal fixtion blade plate, location is supported by spring 12, Magnet 10 plays reinforcement positioning action, prevents toner screw or skidding.Start electric device and drive Hollow trepanning drilling machine 1 quick rotation, when boring cutover hone lamella, start air pump 7 simultaneously, cutter head 4 and cutter tooth 9 are bored the chip cut off by exhaust tube 8 and are pumped in scrap collecting bag 6 in time by air pump 7, thus timely cleared of debris, and air pump 7 can play the effect of cooling in the process of suction chip to cutter head 4 and cutter tooth 9 place, prevent temperature in brill cutover hone lamella process too high; The cutter head 4 of Hollow trepanning drilling machine 1 front end and cutter tooth 9 by the internal fixtion synthetism twist drill around lock screw thoroughly, make the lock screw head of a nail be separated with internal fixtion blade plate, then use corresponding instrument lock screw to be screwed out, thus taken out smoothly by internal fixtion blade plate.
Above-described embodiment just illustrating or explaining technical solutions of the utility model, and the restriction that should not be construed as technical solutions of the utility model, obviously, those skilled in the art can carry out various modifications and variations to this utility model and not depart from spirit and scope of the present utility model.If these amendments and modification belong within the scope of this utility model claim and equivalent technologies thereof, then this utility model also comprises these amendment and modification.
