Abstract
The utility model relates to a miniature charging type electric bone drill. The miniature charging type electric bone drill solves the past problems of complex operation, inconvenient movement and the like, and mainly comprises a charging power supply, a high-speed miniature motor, a motor concentric output connecting rod, a fastening clamp, a drill bit and other components, wherein the fastening clamp effectively fastens the charging power supply, the high-speed miniature motor, the motor concentric output connecting rod and the other components, the charging power supply provides power for operation of the high-speed miniature motor, operation of the high-speed miniature motor drives a main shaft to rotate at high speed, transmission action of the motor concentric output connecting rod and a driven shaft drives the drill bit to rotate synchronously, concentrically and at high speed, and therefore the function of hole drilling is achieved. The miniature charging type electric bone drill is simple in structure, small in size, light in weight, simple to operate, safe, practical, and suitable for medical clinical bone drilling operations, such as craniotomy and vertebral columns.
Description
Technical field
This utility model relates to a kind of electric bone drill, particularly a kind of medical miniature charged electric bone drill.
Background technology
At present, the electric bone drill of selling on domestic market is various, is substantially divided into two types: a kind of is electric bone drill with attaching plug, and itself does not have power supply equipment, this kind equipment general structure is loaded down with trivial details, majority is made up of dynamic host and hand machine head, carries inconvenience, and is subject in use pining down of power line, doctor is in use with change place and orientation, may just need mobile device main frame, and operating switch is on main frame, uses convenient not and flexible; One is battery type electric bone drill, and this kind equipment is relatively simple, flexible, mostly be hand-held, but its body weight is larger, Heavy Weight, and doctor is difficult to grasp, and susceptible is tired out.Therefore, design is a kind of simple in structure, and volume is little, lightweight, easy to operate, flexible, and safe and practical miniature charged electric bone drill is particularly necessary.
Utility model content
The purpose of this utility model be to provide a kind of simple in structure, volume is little, miniature charged electric bone drill lightweight, simple to operate, safe and practical.
The purpose of this utility model realizes by following approach: on the panel of charge power supply (1) termination, power source charges socket (2) is housed, charging indicator light (3) and operating switch (4), high-speed micro motor (5) is connected with charge power supply (1), and by intermediate connector (6) and electric motor protecting cover (7) fixed installation, driven shaft (8) is exported with one heart connecting rod (9) by motor and is connected with high-speed micro motor (5), driven shaft (8) two ends is equipped with respectively fore bearing (10) and rear bearing (11), rear bearing (11) has bearing top shoulder (12) to tighten up, driven shaft (8) overcoat has conical shell (13), conical shell (13) and electric motor protecting cover (7) are tightened driven shaft (8) and the fastening installation of high-speed micro motor (5) by matching thread, in driven shaft (8) front end, be equipped with to bore and chew chuck (14), brill chew (15) by reinforce nut (16) be installed in bore chew in chuck (14), brill chew (15) outer end also overlap have bore dark position limiting clamp (17), boring dark position limiting clamp (17) tightens by matching thread with conical shell (13), bore dark position limiting clamp (17) rear end auxiliary limit screw cap (18) is housed.
The utility model has the advantages that: 1, simple in structure, reasonable in design, this uses novel all parts all to adopt miniature parts, has little, the lightweight feature of volume.2, stable performance, this utility model only has an operating switch, need not make somebody a mere figurehead and speed governing.3, easy to use, practical, adopt charge power supply and due to little, the lightweight feature of its volume, doctor can be easy to implement easily operation.4, consumptive material is few, and cost is lower, and equipment easy to clean and sterilization.
Brief description of the drawings
Fig. 1 is this utility model sectional structure schematic diagram.
Detailed description of the invention
Below with reference to the accompanying drawings to this utility model do further in detail, intactly explanation.
Embodiment 1
In Fig. 1, on the panel of charge power supply (1) termination, power source charges socket (2) is housed, charging indicator light (3) and operating switch (4), high-speed micro motor (5) is connected with charge power supply (1), and by intermediate connector (6) and electric motor protecting cover (7) fixed installation, driven shaft (8) is exported with one heart connecting rod (9) by motor and is connected with high-speed micro motor (5), driven shaft (8) two ends is equipped with respectively fore bearing (10) and rear bearing (11), rear bearing (11) has bearing top shoulder (12) to tighten up, driven shaft (8) overcoat has conical shell (13), conical shell (13) and electric motor protecting cover (7) are tightened driven shaft (8) and the fastening installation of high-speed micro motor (5) by matching thread, in driven shaft (8) front end, be equipped with to bore and chew chuck (14), brill chew (15) by reinforce nut (16) be installed in bore chew in chuck (14), brill chew (15) outer end also overlap have bore dark position limiting clamp (17), boring dark position limiting clamp (17) tightens by matching thread with conical shell (13), bore dark position limiting clamp (17) rear end auxiliary limit screw cap (18) is housed.Charge power supply of the present utility model (1) has storage function, for high-speed micro motor (6) provides electrical source of power, control the high speed rotating of electric machine main shaft (9), the gearing of exporting with one heart connecting rod (9) and driven shaft (8) by motor drives bores the synchronous rotation of chewing chuck (15) and brill and chew (15), holes thereby realize.Reinforce nut (16) effectively brill is chewed (15) be fastened at bore chew in chuck (14); boring the installation of dark position limiting clamp (17) can effectively protect the vibrations of boring while chewing (15) not because of running to fracture; can regulate easily again and bore the degree of depth that pierces of chewing (15); meanwhile, it is further fastening that auxiliary limit screw cap (18) synchronizing moving that bores dark position limiting clamp (17) rear end obtains it.Back-out and bore dark position limiting clamp (17) and reinforce nut (16) and can change easily brill and chew (15), and do not need to dismantle other parts, both improved work efficiency, and effectively protected equipment.The surface of electric motor protecting cover (7) is curved design, is convenient to doctor and easily holding equipment is not felt tired out.
