Description
Technical field
It the utility model is related to a kind of bone drill for having and penetrating indicator function.
Background technology
Have skeletal injury or the patient with osteopathy, reparation in bone, during treatment, it is necessary on bone punching or
Sampling, during bone perforation, bone drill needs to stop drilling operation immediately after drilling through bone, avoids damage to adjacent with drill hole
Marrow, periosteum and its hetero-organization, experienced doctor can be identified by the sound of feel, bone drill, can exact operations, but
It is for young, unfamiliar doctor, is just not easy judgement and identifies whether to drill through bone, while the part that bone drill drills through
Bone is easily accessible ossis or is not easily taken out.
Utility model content
The technical problems to be solved in the utility model is how to overcome the drawbacks described above of prior art, there is provided one kind, which has, wears
The bone drill of saturating indicator function.
In order to solve the above technical problems, there is the bone drill for penetrating indicator function to include core drill, core bar and handle for this, it is described
Core drill includes cylindrical shape hollow boring bit, two retainer rings and a driven tooth being fixed on cylindrical shape hollow boring bit outer wall
Wheel, the core bar front is rounded, core bar rear section is in regular polygon, and it is fixed that an annular is provided between front and rear
Plate, the core bar front end is hemispherical, and is provided with 1 or 2 or 3 fixed pin, and cylindrical shape core drill is stretched into the front portion of the core bar
In head internal cavities, the handle is provided with front end lug boss and rear end lug boss, is in integrally Y-shaped, the front end lug boss
Manhole is provided with, rear end lug boss is provided with regular polygon through hole, and the manhole of handle front end lug boss is enclosed on two
On cylindrical shape hollow boring bit between retainer ring, the rear end of the core bar is located in the regular polygon through hole of handle rear end lug boss
It is interior, and a helical spring is cased with the core bar between ring-type fixing plate and handle rear end lug boss, the front end of the handle is convex
Rise and a motor and a driving gear, the rotating shaft of the driving gear and motor are additionally provided between portion and rear end lug boss
It is fixedly connected, the driving gear is engaged with the driven gear, and push-button switch is additionally provided with the handle.
It is so designed that, core bar rear portion is regular polygon, prevents core bar from rotating, and the fixed pin of core bar full section is pricked on bone,
After bone is drilled through, the bone loss under being drilled, core bar protracts under the elastic force effect of helical spring, prompts doctor's bone
It has been being drilled through that, fixed pin is penetrated in the bone under being drilled, and prevents the bone under being drilled from pushing away forward in people's marrow or its hetero-organization,
When taking out core drill, the bone under being drilled is carried over fixed pin, convenient sampling.
As optimization, the core bar rear section is in regular hexagon through hole, and the regular polygon through hole section is positive six side
Shape.It is so designed that, processing, convenient material drawing.
As optimization, the front end lug boss and rear end lug boss of the handle are that left and right two panels combines, left with
Handle is connected as a single entity, and right is movable part, and left is fixedly connected with right by screw.It is so designed that, is easy to assemble.
The utility model has the bone drill for penetrating indicator function, can indicate whether bone is drilled through, facilitate doctor to operate, group
Fill easy to use, be widely used in Orthopeadic Surgery curative activity.
