Description
Technical field
The present invention relates to bone drill field, the bone drilling device that especially a kind of adjustable length is easy and simple to handle.
Background technology
Clinically, due to some causes of disease, doctor needs to punch with bone drill on the sclerotin of patient, but due to bone drill and sclerotin be not one, be easy to when punching, position be trained off, or boring is comparatively deeply, thus causes some adverse consequencess.
In prior art, Authorization Notice No. is CN 2449663 Y, name is called " a kind of secondary device of bone drill ", and technical scheme is: curved crank is connected with solid brill bowl through the screw on outstanding drilling rod, and outstanding drilling rod is connected with handle upper end, handle, at its lower end is connected with square box, two-way spiral shell axle is successively through the front of square box, and the back of forward and backward splenial bone plate square box, forms square box outside, splenial bone plate is in interior connection, and drill bit length controller is integrated alone; The two sides of handle are parallel to each other, upper end respectively has " L " shape side opening, the upper end of " L " shape side opening is open, it is semi-cylindrical shaped after it, directly be connected with two sides, also can be " work " font after it, the upper and lower horizontal component of " work " font is connected with two sides, vertical portion is cylinder, and side is matsurface with outer surface below; Two-way spiral shell footstalk is for imitative oval, and the hand of spiral at two-way spiral shell axle two ends is contrary, and pitch is equal; Outstanding drilling rod is cuboid, and its two ends are two " H " structures, and first and the 3rd, second equals the spacing of handle two sides with the spacing of the female of the 4th " H " structure; Splenial bone plate is two pieces, and " [" shape structure, backward, forward, its horizontal width equals the interior spacing of square box to rear piece of ledge to front piece of ledge, and it highly equals the length of drill bit length controller.
Be connected with solid brill bowl through outstanding drilling rod by curved crank, coupled in the side opening that outstanding drilling rod can insert handle upper end, the transverse arm that the lower end of handle both sides is stretched out to central authorities is connected with square box, is series in square box with a two-way spiral shell axle by splenial bone plate; Bone drill is fixed in solid brill bowl; Rotating two-way spiral shell axle makes splenial bone plate equidistant to centralized movement, clamps sclerotin, and like this, sclerotin and bone drill are relative to becoming to be integrated, and the relative position of the two remains unchanged, and this just effectively prevent hole scattering.By adjusting the relative position of outstanding drilling rod and handle, when motionless splenial bone plate, once one to two holes can be bored, very convenient; After the hole drill on fracture one broken ends of fractured bone is well, with a screw by Interal fixation on sclerotin, splenial bone plate is moved on to another broken ends of fractured bone steel plate porose place clamping sclerotin, holes, effectively like this ensure that to bore position accurate; Because be that the tip of drill bit is inserted in drill bit length controller when filling drill bit toward brill is upper, hold drill bit length controller and drill bit afterbody is loaded bone drill, fix tightly and remove lower drill bit length controller, the length that such drill bit exposes equals the length of drill bit length controller, and the length of drill bit length controller presets the height equaling splenial bone plate, so when drill bit movement is to sclerotin offside, bone drill is just in time kept off by splenial bone plate resistance, this just effectively prevent pierced dark; According to Newtonian mechanics First Law, interaction force between bone drill and sclerotin, equal and opposite in direction, direction is contrary, is finally all applied on handle, so, the power that sclerotin can be made to be shifted and the direction of power, determined by that hand of doctor's handle, and do not lie in the pressure of bone drill to sclerotin, this is just provided with controllability.
Another part of prior art is Authorization Notice No. is CN 203662843 U, name is called " miniature charged electric bone drill ", technical scheme is: the panel of charge power supply termination is equipped with power source charges socket, charging indicator light and operating switch, height micromachine is connected with charge power supply, and by intermediate connector and the fixed installation of electric motor protecting cover, driven shaft exports connecting rod with one heart by motor and is connected with high-speed micro motor, driven shaft two ends is equipped with fore bearing and rear bearing respectively, rear bearing has bearing top shoulder to tighten up, driven shaft overcoat has conical shell, conical shell and electric motor protecting cover are tightened driven shaft and the fastening installation of high-speed micro motor by matching thread, chuck is chewed built with brill in driven shaft front end, brill is chewed and is installed in brill by solid nut and chews in chuck, brill chew outer end also overlap have bore dark position limiting clamp, bore dark position limiting clamp and conical shell is tightened by matching thread, bore dark position limiting clamp rear end and auxiliary stopper nut is housed.
The charge power supply of this programme has storage function, for high-speed micro motor provides electrical source of power, controls the high speed rotating of electric machine main shaft, and the gearing being exported connecting rod and driven shaft by motor with one heart drives the synchronous axial system boring and chew chuck and chew with brill, thus realizes boring.Reinforce nut effectively brill to be chewed and be fastened at brill and chew in chuck; the installation of boring dark position limiting clamp effectively can be protected to bore to chew and not fracture because of vibrations during running; what brill can be regulated again easily to chew pierces the degree of depth; meanwhile, it is further fastening that the auxiliary stopper nut synchronizing moving boring dark position limiting clamp rear end makes it obtain.The dark position limiting clamp of brill of back-outing can be changed brill easily with reinforcing nut and chew, and does not need to dismantle other parts, both improves work efficiency, and effectively protects equipment.The surface of electric motor protecting cover is curved design, is convenient to doctor and easily holding equipment is not felt tired out.
But existing device cannot regulate accurately to the brill bone degree of depth, makes to threaten at the life of the paired patient of operating process.
