Description
This utility model relates to therapeutic medical a kind of electronic drilling utensil.
Present electric bone drill mainly is made of several most of assemblings of motor, drive mechanism and housing, and the outfan of drive mechanism is for being connected with medical drill bit cutter or fixedlying connected the formula structure with other medical cutter, and regular tap is adopted in the control of motor.The deficiencies in the prior art part mainly is: 1, a kind of drilling tool has only a kind of function, and the classification of cutter is non-exchange, and the description of drilling tool increases, and expense is big; 2, it can only carry out work with a kind of rotating speed, also can not conversion turn to, and uses inconvenience, can not satisfy the actual needs of medical treatment, operation.In addition, more difficult grasp when boring Ke Shi hole and overlength hole, the cutting end of long long drill bit, away from being installed a little, poor stability, beat are big, bring bigger misery to patient; The power supply of motor is the external plug structure, can only can not satisfy the requirement of special circumstances and open-air medical treatment, operation with a kind of fixed mode--mains-supplied work; Housing is a plastic, is unfavorable for disinfecting.
The like product of import except that above-mentioned weak point, exists also that volume is big, operation is not nimble, the drawback of fetch long price.
The purpose of this utility model is to avoid weak point of the prior art, and provides a kind of replaceable cutter classification, conversion rotating speed, the multifunctional motor-driven bone drill product that turns to.
Can take following technical scheme to realize purpose.The multifunctional motor-driven bone drill still is made of a few part assemblings of motor, drive mechanism and housing, but at the output axle head of drive mechanism dop is housed; One end is set can be cooperated with dop, and end can bore the cutter axis that is connected with drill bit, bone saw, cranium respectively in addition; The stepless speed regulation on and off switch is adopted in the control of motor, also is connected to forward-reverse switch between stepless speed regulation on and off switch and motor.
Under the prerequisite that satisfies the said structure requirement, specific constructive form, size as for the integral body of multifunctional motor-driven bone drill, each funtion part, each zero member, the mode that is connected and fixed between member, position relation etc., all can be according to using needs, take the circumstances into consideration to set, they can both realize purpose, guarantee the serviceability and the effect of this multifunctional motor-driven bone drill.
The relative prior art of the technical program has following advantage and effect:
Multiple function, the classification of replaceable cutter as the various drill bits of adapted or bone saw or cranium brill etc., reduces the description of drilling tool, cost saving; Its continuously variable carries out work, also convertible turning to, and performance is comprehensive, and use extremely flexibly, conveniently can adapt to the actual needs of medical treatment, operation.
In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.
Fig. 1 is a kind of structural representation of multifunctional motor-driven bone drill;
Fig. 2 is a kind of structural representation of drill bit axis;
Fig. 3 is a kind of structural representation of bone saw axis;
Fig. 4 is a kind of structural representation of cranium drill chuck axle;
Fig. 5 is the wiring diagram of motor controling switch.
Among the bone drill of multifunctional motor-driven shown in the accompanying drawing embodiment, stepless speed regulation on and off switch 4 adopts MOD15-07B, and it is fixed on the switch heat sink 3, be installed in the bone drill shank; Also be connected to forward-reverse switch 5 between stepless speed regulation switch and motor 8, it adopts the TUR1 type to constitute.Shown in accompanying drawing 1,5.Forward-reverse switch beat to a side if motor for just changeing, beat when opposite side and reverse.The stepless speed regulation switch slowly runs when touching handle, and along with the increase of pressing force, rotating speed increases.
The multifunctional motor-driven bone drill, the socket that the power supply employing of motor cooperates with battery, and purchase the external plug member that cooperates with this socket.As adopting the female type structure that cooperates with the KR23/43 battery, both can take the external commutation supply voltage of civil power, also can directly use battery powered, to satisfy the requirement of various special circumstances and open-air medical operating.KR23/43 battery or battery type external plug be inserted into contact in the socket connector of bone drill shank lower end, with conducting strip 2 good after, it is firm to be fixed with bolt 1, assurance contacts well, reliable operation.
Among the embodiment, the housing of multifunctional motor-driven bone drill is a stainless steel products.Very clean, be beneficial to and disinfect.
Among the multifunctional motor-driven bone drill embodiment, dop is by the spring 11, ball 15 and the spring cover 13 that are installed in successively on the hollow output gear shaft 12, with the structure that collar 14 axial location are constituted in hollow output gear axle head, the front end of hollow output gear shaft is provided with the collar groove, there is ball hole the appropriate position.The cutter axis comprises drill bit axis 16, bone saw axis 17 and cranium drill chuck axle 18, shown in accompanying drawing 2,3,4; They are that an end is provided with the ball positioning groove hole for optical axis, the axle that can be plugged in the output gear shaft hollow hole, and the middle part is the shaft shoulder, and end is respectively the awl post that cooperates with drill bit, the external screw thread that cooperates with bone saw, cranium brill in addition.The shaft shoulder at cutter axis middle part on demand, can be made the fastening side of usefulness platform.With hollow output gear shaft coaxial line through tube 7 is housed also in the housing 6.During use, to the spring cover of pusher dop, earlier with one of cutter axis, insert in the dop hole with the optical axis end, slotted eye is facing to ball, looses one's grip after putting in place, the spring cover resets, and ball advances the axis location notch hole, and the cutter axis is blocked the jail; Assemble various existing medical drill bits or bone saw or cranium brill etc. at the other end of axis on demand again; Energized gets final product work.When boring Ke Shi hole and overlength hole, long drill bit is through hollow output gear shaft, be contained in the through tube with one heart, and the cutting end is a little near from being installed, and cutter moves with the need outward, and is accurate to neutrality, is easy to grasp, good stability, and beat is little, can obviously alleviate patient's misery.
Serviceability, the result of use of the bone drill of multifunctional motor-driven shown in accompanying drawing embodiment are good.
