Abstract
The utility model discloses an orthopedic drilling device which comprises a sleeve and a screw tap inserted into the sleeve, wherein length graduations are arranged on the screw tap; a rotating rod hole is formed at the top end of the screw tap; a rotating rod is inserted into the rotating rod hole; the orthopedic drilling device further comprises two supports fixed on the sleeve; the top ends of the supports intersect; a fixing bolt is arranged between the intersecting part of the two supports and the sleeve; and a long strip slot is formed on each support. The orthopedic drilling device has the beneficial effects that (1) the structure is simple; (2) as the two supports are arranged at the bottom of the sleeve, the long strip slots are formed on the supports and the fixing bolt is arranged between the supports and the sleeve, the sleeve and the screw tap can be perpendicular to a bone and cannot deviate or be displaced through adjusting the positions of the supports; and (3) as the length graduations are arranged on the screw tap, the drilling depth can be directly read, so that the drilling precision is high.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of orthopaedics drilling equipment.
Background technology
At present, in medical practice, for fracture site is fixed; Usually need on bone, hole, with steel nail or bolt fracture site is fixedly connected then, still; Because each hospital all adopts the instrument of screw tap as boring, thereby boring time, the direction in the hole that is drilled through and the degree of depth all can only rely on doctor's experience judgement; Precision is relatively poor, and can influence next step work.
Summary of the invention
The problem that this utility model will solve is: a kind of simple in structure, orthopaedics drilling equipment that borehole accuracy is high is provided.
In order to solve the problems of the technologies described above, the orthopaedics drilling equipment of this utility model comprises sleeve and is inserted in the screw tap in the sleeve; Said screw tap is provided with the length scale; The top of said screw tap is provided with a swing arm hole, is inserted with a swing arm in the said swing arm hole, also comprises two supports that are fixed on the sleeve; The top of said support intersects, and is provided with a set bolt between the intersection of said two supports and the sleeve.
For the ease of the height and the angle of adjustment support, the orthopaedics drilling equipment of this utility model is equipped with rectangular groove on the said every support.
The beneficial effect that this utility model is obtained is: (1) is simple in structure; (2) telescopic bottom is provided with two supports, and support is provided with rectangular groove, is provided with set bolt between support and the sleeve, thereby through adjusting the position of support, can make sleeve and screw tap perpendicular to bone, can not be partial to and be shifted; (3) screw tap is provided with the length scale, can directly read the degree of depth of boring, thereby borehole accuracy is high.
Description of drawings
Fig. 1 is the structural representation of this utility model.
Among the figure: 1, swing arm hole, 2, screw tap, 3, swing arm, 4, the length scale, 5, sleeve, 6, set bolt, 7, support, 8, rectangular groove.
The specific embodiment
As shown in Figure 1, the orthopaedics drilling equipment of this utility model comprises sleeve 5 and is inserted in the screw tap 2 in the sleeve 5; Said screw tap 2 is provided with length scale 4; The top of said screw tap 2 is provided with a swing arm hole 1, is inserted with a swing arm 3 in the said swing arm hole 2, also comprises two supports 7 that are fixed on the sleeve 5; The top of said support 7 intersects, and is provided with a set bolt 6 between the intersection of said two supports 7 and the sleeve 5; Be equipped with rectangular groove 8 on the said every support 7.
In boring time,, the position of two supports 7 of adjustment makes sleeve 5 and screw tap 2 perpendicular to bone, tightens set bolt 6 then, so just can guarantee that sleeve 5 and screw tap 2 perpendicular to bone, can not be partial to and be shifted, and rotates swing arm 3 at last, and on bone, holing gets final product.
The orthopaedics drilling equipment of this utility model in the process of boring, because screw tap 2 is provided with length scale 4, therefore can directly read the degree of depth of boring, and borehole accuracy is high.
This utility model is not limited to above-mentioned embodiment, and anyone should learn the structural change of under the enlightenment of this utility model, making, every with the utlity model has identical or close technical scheme, all fall within the protection domain of this utility model.
