Medical micro-bistrique comprises spherical grinding machine head and axle, and in the prior art, existing spherical grinding machine head diameter is bigger, and axle is a straight-bar.Though structure is simpler, easy to make, but do not have the adaptability and the versatility of individuality relatively poor, the tract that is not easy to go deep into catwalk in use and needs just can reach through curved pathway, has certain limitation as in internal ear, middle ear and tympanum plastic operation, going deep into the inner passage operation, using.And straight-bar axle and handle be on same straight line, incompatibility operator's sight line, and when operation, surgical field of view is easily blocked by shank and motor, influences operation technique.
Therefore, need improve existing medical micro-bistrique, the deep enough tract of energy with certain crooked route, have the adaptability of individuality and stronger versatility, favourable accurate cutting operation to osseous tissue, operator's sight line is moved towards noiseless, and surgical field of view is good, guarantees carrying out smoothly of operation.
The utility model content
In view of this, this utility model provides a kind of medical micro-bistrique, the deep enough tract of energy with certain crooked route, have the adaptability of individuality and stronger versatility, favourable accurate cutting operation to osseous tissue, operator's sight line is moved towards noiseless, and surgical field of view is good, guarantees carrying out smoothly of operation.
Medical micro-bistrique of the present utility model comprises elastic central spindle, and described elastic central spindle front end fixedly installs grinding machine head, and tail end is provided with grip shank in the circumferencial direction secure fit, elastic central spindle's flexible pillar of overcoat that is rotatably assorted.
Further, described grinding machine head is spherical, and diameter is 0.5mm-5mm;
Further, described grinding machine head diameter is 0.5mm-2mm;
Further, described elasticity pillar is made up of the straight tube leading portion that is connected as a single entity, arc stage casing and straight tube rear;
Further, also comprise the sealing shroud of hermetically sealed case in elastic central spindle, described sealing shroud is positioned at straight tube leading portion front end and its secure fit of elasticity pillar;
Further, the outer surface of described elasticity pillar is provided with heat insulation layer;
Further, the straight tube rear of described elasticity pillar is with fixed cover outside the circumferencial direction secure fit;
Further, described fixed cover rear formation cross section is the polygonized structure that cooperates with micro-mill handle;
Further, circle is provided with heavy stand in the straight tube leading portion front end of described elasticity pillar, and described sealing shroud rear cylindrical sinks to forming the shaft shoulder, and the sealing shroud rear inserts its secure fit of heavy stand Duan Bingyu of straight tube leading portion front end vertically.
The beneficial effects of the utility model: medical micro-bistrique of the present utility model, mandrel component adopts elastic construction, can have certain crooked radian, the deep enough tract of energy with certain crooked route, have the adaptability of individuality and stronger versatility, favourable accurate cutting operation to osseous tissue moves towards noiseless to operator's sight line, surgical field of view is good, guarantees carrying out smoothly of operation.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further described.
