Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is structural representation of the present invention.
Fig. 2 is theory diagram of the present invention.
Fig. 3 is that bone drill of the present invention drills skeleton moment current of electric change schematic diagram.
Fig. 4 is the pressue-graph that bone drill of the present invention is about to drill skeleton pressure transducer.
Detailed description of the invention
Fig. 1 is structural representation of the present invention, Fig. 2 is theory diagram of the present invention, as shown in the figure, one provided by the invention automatic stall formula bone drill, the motor-drive circuit 3 that the motor 5 at least comprise drill bit 1, driving drill bit 1 to rotate and drive motors 5 work, also comprises the control module 4 controlling motor 5 stall for drilling bone at bone drill instantaneously;
Described control module 4 comprises the current acquisition unit for gathering motor 5 electric current, the current comparison circuit be electrically connected with current acquisition unit outfan, the control unit be electrically connected with described current comparison circuit outfan and the on-off circuit be connected with control unit outfan, described on-off circuit is arranged at the break-make of the supply access controlling motor-drive circuit 3 between power supply and motor-drive circuit 3, described control unit is according to the open and close of the sudden transformation gauge tap circuit of motor 5 electric current, described current acquisition unit is current sensor or current detection circuit, described control unit is arm processor or single-chip microcomputer, such as single-chip microcomputer 89C52 series monolithic, AVR single chip etc., current acquisition unit and control unit all can adopt existing techniques in realizing, do not add at this and repeat, skeleton moment is drilled at bone drill, current of electric there will be obvious sudden transformation, as shown in Figure 3, therefore, in bone drill work process, the curent change of motor is gathered by current acquisition unit, then be input to current comparison circuit to compare, electric current compare threshold is provided with in current comparison circuit, current of electric is within the scope of this electric current compare threshold, show bone drill still at work, but also do not drill skeleton, control unit no-output, when detecting that current of electric is greater than electric current compare threshold, control unit exports cut-out control command immediately, on-off circuit is interrupted, cut off the supply access of motor, thus make bone drill stall, because skeleton is generally hollow structure, bone drill there will be twice and drills bone, first time for drill skeleton after the trip-out sidetracking of skeleton enters, bone drill is made to extend into space in skeleton, although now there is first time Spline smoothing in electric current, control unit does not still export control command, when bone drill drills the relative side of trip-out side in skeleton, there is second time Spline smoothing and be greater than current threshold in current of electric, now export control command by control unit and make on-off circuit action, disconnect the supply access of motor-drive circuit, make motor stalling.
In the present embodiment, described bone drill also comprises the verification detection module simultaneously worked with current acquisition unit, described verification detection module comprises pressure transducer 6 and pressure comparison circuit, the outfan of described pressure transducer 6 is connected with the input of pressure comparison circuit, the outfan of pressure comparison circuit is electrically connected with described control unit, verification detection module and control module work simultaneously, the pressure curve that pressure transducer exports as shown in Figure 4, when bone drill is about to drill skeleton, pressure there will be obvious Spline smoothing, pressure transducer output signal is transferred to pressure comparison circuit, pressure compare threshold is provided with in pressure comparison circuit, when pressure is greater than pressure compare threshold, then show that bone drill is about to drill skeleton, and pressure comparison circuit exports comparative result to control unit, the comparative result that control unit exports according to current comparison circuit carries out comprehensive descision, namely when all there is Spline smoothing in electric current and pressure, control unit exports control command to on-off circuit, thus control bone drill stall, thus ensure the reliability of bone drill stall, certainly, due to the hollow structure of skeleton, pressure transducer also there will be twice Spline smoothing in brill bone process, therefore, when all there is second time Spline smoothing in pressure and electric current, control unit just exports control command, described verification detection module and current acquisition unit for subsequent use each other, namely when verify detection module or current acquisition unit one of them break down no-output time, control unit then only detects a wherein road signal, then when second time Spline smoothing or pressure appearance second time Spline smoothing appear in electric current, control unit all exports stall control command, effectively can control the reliability of bone drill stall, described pressure transducer is the pressure transducer of the JHBM model of golden promise.
In the present embodiment, described bone drill also comprises the ultrasonic transducer 8 piercing the degree of depth for detecting drill bit, the outfan of described ultrasonic transducer is connected with control circuit input, in use, using the surface of bone of the trip-out side of skeleton or for locate knochenbruch steel plate as reference plane, judge by the distance change between ultrasonic transducer and reference plane the degree of depth that bone drill pierces, thus ensure the accuracy of operation, such as select the length of screw.
In the present embodiment, described bone drill also comprises for the handle 7 fixedly mounting drill bit 1 and the bone drill housing 2 of motor 5 and be fixedly connected with bone drill housing 2, described pressure transducer 6 is arranged at the rear side of handle 7, the palm of the hand position of doctor is in use made to push down pressure transducer, ensure that pressure sensing appliance has constant output valve when boring bone, and ensure that only pressure just sudden transformation can occur when bone drill is about to drill skeleton, thus ensure the reliability of control, ultrasonic transducer 8 is arranged at the front end of bone drill housing 2, described control module is arranged in bone drill housing, front and back in the present embodiment refer to that one end that bone drill housing is provided with drill bit is front end, then contrary with drill bit direction one end is rear end, therefore, handle and drill bit are front side towards identical side, opposite side is rear side.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
