Embodiment 1
Attached drawing 1 is please referred to, Fig. 1 is a kind of structural schematic diagram of operation impact drill of the utility model.A kind of operation punching
Hit brill, the operation impact drill include AO drill bit 1, scroll chuck 2, transmission shaft 3, shaft 4, shaft coupling 5, direct current generator 6,
Ball grooves 7, shell 8；The AO drill bit 1 is clamped by scroll chuck 2；The three chucking chuck 2 and 3 front end stationary phase of transmission shaft
Even；3 end of transmission shaft is fixed with left metal dish 31；Bearing 32 is cased on the transmission shaft 3；The shaft 4
Front end is fixed with right metal dish 41, and the right metal dish 41 can be engaged with left metal dish 31；The shaft 4
Outside is cased with spring 42；The shaft coupling 5 connects shaft 4 and end is connected with direct current generator 6；The ball grooves 7 are nested
Between shaft 4 and shell 8；Spring stop 81 is equipped in the shell 8 at 42 position of spring；Outside the shell 8
Position is equipped with switch 82 at handle.
It should be understood that the impact drill is integrally in hand-held shape, it is easy to use；The operation impact drill can
Complete machine autoclave sterilization, disinfecting time are short；The transmission shaft 3 and shaft 4 can be axially moveable；When shaft 4 rotates, Gu
Fixed left metal dish 31 is gradually separated with the right metal dish 41 of rotation along serrated grip faces, when left metal dish 31 and right metal dish 41
It is kept completely separate in a flash, shaft 4 will receive the pressure from spring 42, so that left metal dish 31 is stung again with right metal dish 41
It closes, while converting impact force for the pressure from spring 42 and passing to transmission shaft 3, eventually arrive at AO drill bit 1, move in circles,
It being formed intensively, oscillation frequency is high, the lesser microshock of amplitude, the cortical bone of hardness height but finite thickness can be easily penetrated,
Without as common Medical orthopedic electric drill, need it is certain force on bone face, can realize drilling, thus avoid because of bone
The curvature on surface causes drill bit when drilling to slide, injures surrounding tissue, the risk of unnecessary pain is brought to patient；It is described
Transmission shaft 3 and the axis direction times of exercise of shaft 4 have with the sawtooth contact surface between left metal dish 31 and right metal dish 41
Subject to how many a sawtooth, i.e. 4 every revolution of shaft will generate the reciprocating motion with the axis direction of sawtooth number same number,
While to realize that rotation pierces, axially there is the impact of slight high frequency to shake, when being drilled, penetration power is stronger；Institute
Usually there is difference with hand drill medical at present in a manner of power in the impact drill in the utility model stated, current medical hand drill
In the functions such as goose saw, AO, drill bit, with the realization of distinct interface module, and the impact drill in the utility model impacts gear
Structure change is shaken for AM access module realization, and there is good penetration power, can stablize, accurately punch in bone surgery.
Embodiment 2
Attached drawing 4 is please referred to, Fig. 4 is the structural schematic diagram of the utility model another kind operation impact drill.The present embodiment with
Embodiment 1 is essentially identical, the difference is that, the operation impact drill shell 8 in the present embodiment is equipped with depthometer 9 and opens
Shut 10；The depthometer 9 is set to shell side, and top parallel with drill bit is aligned；The depthometer 9 is by fixed block 91
Clamping；The switch lock 10 is set to cover top portion；The depthometer 9 can help medical worker to understand the depth that drill bit pierces
Degree refines operation more；When the switch lock 10 locks, switch 82 will be unable to starting direct current generator 6, and doctor is effectively reduced
The risk for personnel misoperation of being engaged in, makes to perform the operation safer.
A kind of operation impact drill of the utility model, it is whole in hand-held shape, it is easy to use；The microshock of formation is intensive,
Oscillation frequency is high, and amplitude is smaller, can easily penetrate the cortical bone of hardness height but finite thickness, without as common Medical orthopedic electricity
Bore like that, need it is certain force on bone face, can realize drilling, thus avoid the curvature because of bone surface, cause to drill
When drill bit slide, injure surrounding tissue, the risk of unnecessary pain brought to patient；Depthometer can help medical worker
The depth that solution drill bit pierces, refines operation more；The risk of medical worker's maloperation can be effectively reduced in switch lock, makes hand
Art is safer.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
Art personnel can also make several improvement and supplement under the premise of not departing from the utility model method, these are improved and supplement
