Abstract
The invention provides a technical scheme of an abrasion drill for an orthopedic operation. The abrasion drill comprises a grinding head and a drill rod fixedly connected with the grinding head. The scheme is characterized in that the grinding head is fixedly connected with the drill rod in a way that the axis of the drill rod is deviated from the axis of the grinding head. The scheme is concretely characterized in that the grinding head is made of a high-hardness stainless steel material. The diameter of the grinding head ranges from 6mm to 12mm. The drill rod is made of a high-strength and high-toughness stainless steel material. The diameter of the drill rod ranges from 3mm to 5mm. By adopting the structure, the drill rod and the grinding head are caused to be eccentric, the range of necrotic bone tissues located inside a bone and cut by using the eccentric abrasion drill in an operation is far larger than the diameter of the grinding head, and the abrasion drill is suitable for an operation for repairing the necrotic bone tissues at minimal invasion.
Description
Technical field
What the present invention relates to is a kind of medical surgical instrument, especially a kind of osseous surgery abrasive drilling.
Background technology
In the prior art, the technical scheme that approaches the most with the application is that present osseous surgery is in the abrasive drilling of use, the drill rod axis of this existing abrasive drilling be all with the bistrique axis on same straight line, it is coaxial configuration, the abrasive drilling of this structure can only machine away the necrotic bone tissue identical with the bistrique diameter when operation, can cut and remove being limited in scope of inside bone necrotic bone tissue, be not suitable for repairing under Wicresoft the operation use of necrotic bone tissue, this is the existing weak point of prior art.
Summary of the invention
Technical problem to be solved by this invention, be exactly for the existing deficiency of prior art, and a kind of osseous surgery technical scheme with abrasive drilling is provided, this scheme adopts the eccentric structure of the axis runout bistrique axis of drilling rod, eccentric abrasive drilling like this can be cut the diameter that the scope of removing inside bone necrotic bone tissue will be far longer than bistrique, is applicable to repair under Wicresoft the operation of necrotic bone tissue.
This programme is achieved by the following technical measures: the osseous surgery abrasive drilling, include bistrique and the drilling rod that is fixedly connected with bistrique, and the characteristics of this programme are that described bistrique is the axis of the axis runout bistrique of drilling rod with being fixedly connected with of drilling rod.The concrete characteristics of this programme also have, and described bistrique is to adopt the stainless steel material of high rigidity to make.The diameter of described bistrique is between the 6-12 millimeter.Described drilling rod is to adopt the stainless steel material of high strength, high tenacity to make.Described drill pipe diameter is between the 3-5 millimeter.
The beneficial effect of this programme can be learnt according to the narration to such scheme, due in this scheme, the axis of the axis runout bistrique of drilling rod, this structure, cause the bias of drilling rod and bistrique, eccentric abrasive drilling like this can be cut the diameter that the scope of removing inside bone necrotic bone tissue will be far longer than bistrique in operation, be applicable to repair under Wicresoft the operation of necrotic bone tissue.This shows, the present invention compared with prior art has outstanding substantive distinguishing features and significant progressive, and the beneficial effect of its enforcement is also apparent.
Description of drawings
Fig. 1 is the structural representation of the specific embodiment of the invention.
In figure, 1 is drilling rod, and 2 is bistrique.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below by a specific embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
Can find out by accompanying drawing, the osseous surgery abrasive drilling of this programme, there is the stainless steel material that adopts high rigidity to make the drilling rod 1 that bistrique 2 and the stainless steel material of the employing high strength that is fixedly connected with bistrique 2, high tenacity are made, the described bistrique 2 of this programme is the axis of the axis runout bistrique 2 of drilling rod 1 with being fixedly connected with of drilling rod 1, is the fixing of a kind of eccentric structure.The diameter of described bistrique 2 is between the 6-12 millimeter, and what this specific embodiment adopted is the bistrique 2 of 8 mm dias.What described drilling rod 1 diameter this specific embodiment between the 3-5 millimeter adopted is the drilling rod 1 of 4 mm dias.
