The utility model discloses a general-purpose hollow nail guide for orthopedics, which comprises an L-shaped rod body formed by a cross bar and a longitudinal bar. A movable longitudinal bar perpendicular to the cross bar is slidably connected to the cross bar. A fixed cone is provided at the end of the rod, and a guide cone corresponding to the fixed cone is provided at the end of the movable longitudinal rod. The center line of the fixed cone and the center line of the guide cone are on the same straight line, and the center line of the guide cone There is a guide hole through it, the movable longitudinal rod in this orthopedic universal hollow nail guide can slide relative to the horizontal rod, and the position of the movable longitudinal rod can be adjusted so that the fixed cone at the end of the longitudinal rod and the guide cone at the end of the movable longitudinal rod are respectively in the The nailing position is predetermined, and the hollow needle is inserted through the guide hole of the guide cone. Since the centerline of the fixed cone and the centerline of the guide cone are on the same straight line, it is only necessary to determine the positions of the fixed cone and the guide cone to ensure the hollow needle. Accurate insertion of the needle, convenient operation and accurate positioning.
Description
Technical field
this utility model relates to orthopedic medical device field, particularly a kind of hollow nail guider.
Background technology
at present, Orthopedic Clinical carries out in the processing of joint, and hollow nail is conventional fixation device, is most commonly used to avulsion fracture of greater tuberosity of humerus, intercondylar fracture of the humerus, intercondylar fracture of the femur, fracture of the tibial plateau, fracture of femoral neck, fracture of medial malleolus, fracture of calcaneus.While inserting hollow nail in operation, rule of thumb insert with operation skill often, its accuracy is had a greatly reduced quality, repeatedly failed hollow nail insert can cause interior fixing not firm, the existing special-purpose guider also existing for certain type of fracture, but there is inconvenience because of the difference of fracture concrete condition and Skeletal size.
Utility model content
Technical problem to be solved in the utility model is to provide the general hollow nail guider of a kind of orthopaedics easy to use, accurate positioning.
For solving the problems of the technologies described above adopted technical scheme: the general hollow nail guider of a kind of orthopaedics, comprise the L shape body of rod being formed by cross bar and vertical pole, on described cross bar, slidably connect one with the perpendicular movable vertical pole of cross bar, in described vertical pole end, be provided with a fixed cone, in described movable vertical pole end, be provided with a guide cone corresponding with fixed cone, the centrage of described fixed cone and the centerline of guide cone are on same straight line, and described guide cone center is run through and had a pilot hole.
Be further used as the improvement of technical solutions of the utility model, the diameter of described pilot hole is 0.5,1,1.5,2,2.5 or 3 millimeter
Be further used as the improvement of technical solutions of the utility model, on institute's cross bar, sign has scale.
Be further used as the improvement of technical solutions of the utility model, described movable vertical pole the other end is provided with the regulating part that holds fixing movable vertical pole.
Beneficial effect: movable vertical pole cross bar slippage relatively in the general hollow nail guider of this orthopaedics, the position of adjusting activity vertical pole, make the fixed cone of vertical pole end and the guide cone of movable vertical pole end respectively in predetermined nailing position, hollow needle is inserted through the pilot hole of guide cone, because the centrage of fixed cone and the centerline of guide cone are on same straight line, therefore only need determine the position of fixed cone and guide cone, just can guarantee that hollow needle accurately inserts, easy to operate, accurate positioning.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is described further;
Fig. 1 is the structural representation of this utility model embodiment.
The specific embodiment
With reference to Fig. 1, the general hollow nail guider of a kind of orthopaedics of this utility model, comprise the L shape body of rod being formed by cross bar 1 and vertical pole 2, on cross bar 1, slidably connect one with the perpendicular movable vertical pole 3 of cross bar 1, in vertical pole 2 ends, be provided with a fixed cone 4, in movable vertical pole 3 ends, be provided with a guide cone 5 corresponding with fixed cone 4, the centerline of the centrage of fixed cone 4 and guide cone 5 is on same straight line, and guide cone 5 centers are run through and had a pilot hole 6.
Movable vertical pole 3 cross bar 2 slippages relatively in the general hollow nail guider of this orthopaedics, the position of adjusting activity vertical pole 3, make the fixed cone 4 of vertical pole 1 end and the guide cone 5 of movable vertical pole 3 ends respectively in predetermined nailing position, hollow needle is inserted through the pilot hole 6 of guide cone 5, because the centrage of fixed cone 4 and the centerline of guide cone 5 are on same straight line, therefore only need determine the position of fixed cone 4 and guide cone 5, just can guarantee that hollow needle accurately inserts, easy to operate, accurate positioning.
In the present embodiment, the L shape body of rod that cross bar 1 and vertical pole 2 are formed in one, the other end of movable vertical pole 3 has a shape and the cross bar 1 cross sectional shape corresponding pilot hole that matches, by this pilot hole, make movable vertical pole 3 be sleeved on cross bar 1 and can move along cross bar 1 length direction, movable vertical pole 3 the other end are provided with the regulating part 7 that holds fixing movable vertical pole 3, particularly, this regulating part 7 is a threaded column, at movable vertical pole 3 other ends, have a screwed hole, threaded column is threaded on the screwed hole of movable vertical pole 3, turning threaded column can make its one end support to be pressed on cross bar 1, thereby make movable vertical pole 3 clamping relative to cross bar 1 fixing.
Guide cone 5 is detachably changed, guide cone 5 has six kinds of specifications, pilot hole 6 diameters in the guide cone 5 of every kind of specification are not identical, the diameter of pilot hole 6 can be designed to 0.5,1,1.5,2,2.5 or 3 millimeter, by dismounting, follow the guide cone 5 that changes different size, just can match with different size hollow nail applicable, the suitability that is conducive to improve this hollow nail guider.Fixed cone 4 is also dismountable, at the circle end face of fixed cone 4 and guide cone 5, is all provided with antiskid thread, can installation fixed cone 4 for convenience detach and guide cone 5.
On cross bar, sign has scale, can accurately measure the degree of depth of inserting hollow nail, reduces operating procedure.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but this utility model is not limited to above-mentioned embodiment, in the ken possessing at described technical field those of ordinary skill, can also under the prerequisite that does not depart from this utility model aim, make various variations.
