Summary of the invention
The purpose of this utility model is to provide a kind of structure dexterity, is fit to the novel medical hollow operation electric drill that operation is used.
A kind of medical hollow orthopaedics electric drill that this utility model provides by handle, battery case, speed-regulating switch, two-direction switch, driver (main frame), clamper (chuck), and form with parts such as chargers.
This utility model is produced the microsurgery electrical equipment for many years by accumulation in R﹠D process experience, according to the characteristics of human engineering and the requirement of orthopaedics electrical equipment, develop medical hollow operation electric drill, its driver console switch and arrangements for speed regulation, structure is simple especially, easy for operation, functional.Price only is 1/3rd of the similar apparatus of import, for hospital provides the product of cheap thing U.S., is doctor and patient service.
This utility model adopts the hollow shaft structure and the decelerator mechanism of particular design.Compare with external like product, simple in structure light and handy, the mixing governing system that mechanical speed governors combines with electrical speed regulation under the condition of same input power, improves the output torque, just saves the energy.Product in the market adopts pure electrical speed regulation system, and timing under the rotating speed is because that output descends is very fast, so that torque descends is also very fast.This utility model has overcome this shortcoming, has improved properties of product.
This utility model is realized the production domesticization of medical hollow operation electric drill, and development is fit to the product of Chinese bone surgery characteristics, saves foreign exchange.Product price is low, is more convenient for popularizing and uses.
Below, describe details and working condition in conjunction with the accompanying drawings and embodiments in detail according to the concrete device that the utility model proposes.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the cross-sectional view of Fig. 1.
Fig. 3 is the structural representation of driver among Fig. 2.
Specific embodiments
Shown in accompanying drawing 1,2, a kind of medical hollow orthopaedics electric drill that this utility model embodiment provides is the pistol shape, and it mainly is made up of parts such as handle 1, speed-regulating switch 2, two-direction switch 3, driver 4, clampers 5.Wherein, described speed-regulating switch 2, two-direction switch 3 are installed on the described pistol shape electric drill handle 1, described driver 4 is a pistol shape drill body part, in the rifle head part of described pistol shape electric drill described clamper 5 is installed, and on described clamper 5 Kirschner wire 6 can be installed.
As shown in Figure 2, be battery case in the middle of the handle 1 described in the utility model, set of cells 9 is installed, in the bottom of described handle 1 battery cover 10 is installed also.The characteristics of electronic hand-held apparatus during battery operation, become organic combinative structure-battery case handle with battery case with handle design.Ni-MH battery is housed in the handle, can repeated multiple times charges, and have the characteristics of heavy-current discharge, it act as driver 4 dc source is provided.
The speed-regulating switch 2 that this utility model provides is by adopting linear Hall integrated circuit and two blocks of magnet steel to form, make magnet steel move the variation that produces magnetic field intensity by button on the Hall element surface, make linear rising of linear Hall circuit output voltage or decline, reach speed regulating control, its effect is an output speed of regulating driver 4.
The two-direction switch 3 that this utility model provides is dialled and is moved key by adopting switch Hall integrated circuit and one block of magnet steel to form, and mobile magnet steel changes magnetic field intensity, hall element output voltage generation saltus step, i.e. " 0 ", level"1"; Thereby the rotating of control motor 13 changes.Hall element has waterproof and high temperature-resistant disinfected function after sealing is handled.Because magnet steel and Hall element are contactless control, therefore has feature of long life.
The driver 4 that this utility model provides is parts of a particular design, the version of driver is a lot, a kind of is that the core motor axle is directly driving, direct drives structure, and its advantage is simple in structure, shortcoming is after motor shaft is processed into hollow, in order to guarantee the intensity of motor shaft, its size is amplified, make the whole amplification of motor overall dimensions, thereby make whole driver profile huge, use inconvenient; Other has the driver of two parallel axes structures, the axial line of drive motors and clamper separated motor reducer and clamper are contained in one on the whole, can whole change, advantage is when the different instrument of use different output speeds to be arranged, adaptability is strong, and shortcoming is the complex structure heaviness.
The comprehensive said structure advantage of the architectural feature of the driver 4 of a kind of medical hollow orthopaedics electric drill that this utility model embodiment provides, particular design goes out the structure of two parallel axes line styles, and it mainly comprises motor and decelerator 8, casing 12, hollow rotating shaft 11, machine driven system gear 7; The described pair of not detachable structure of parallel axes promptly is arranged on larger-size motor 13 and deceleration system 8 on the same axial line, with the axis parallel on the described hollow rotating shaft 11; The machine driven system gear of reuse compact conformation and clamper 5 are connected to an integral body, the physical dimension of hollow rotating shaft 11 and clamper 5 is greatly reduced, the driver contour structures is compact simple, flexible and convenient to use, and it is characteristics of the present utility model that manufacturing cost reduces.
This utility model clamper and deceleration system are designed to the not detachable form of integral body, and motor and deceleration system drive clamper by gear (or sprocket wheel) and rotate, thereby driven tool are rotated on same axis.See accompanying drawing 3 medical hollow operation electric drill activation configuration sketch maps for details, motor 13 drives decelerator 8, decelerator 8 orders about gear train assembly 7 and rotates, because output gear in the gear train assembly 7 and hollow axle 11 rotate so drive hollow axle 11 simultaneously for rigidly fixing.Hollow axle 11 drives the clamper 5 that is fixed on the hollow axle 11 and rotates when rotating, clamper 5 drives clamping when rotating utensil Kirschner wire 6 rotates, and has realized the needed function of operation.
The clamper 5 that this utility model provides is to adopt general electrical components, and it is convenient to buy, as adopting the precision stainless steel chuck of U.S. JACOBS board.
This utility model also can have the adnexa charger, and it also is the general parts of medical electric device.
The domestic market is difficult to see the like product of the medical hollow orthopaedics surgical electric drill that provides with this utility model at present, because this utility model product structure is simple, and stable performance, easy to use, low price obtains users' welcome.This utility model operation precision height, patient's wound can reduce, and can accelerate rehabilitation speed, more not only saves money but also comfortable with routine operation.Promoting the use of of this utility model product can be improved therapeutic effect, and the rehabilitation of accelerating patient body has very great help, and product adopts green battery, and safety and sanitation are free from environmental pollution, but cross infection is stopped in high-temperature steam sterilization again after battery case takes out, and be safe in utilization.
