Abstract
The utility model relates to a thighbone twist locking intramedullary nail which comprises the near end and a nail rod. The near end and the nail rod are of a hollow integrated structure, the tail end of the nail rod is the far end, the near end is horizontally arranged, a first angle is formed between the nail rod and the horizontal plane of the near end, a second angle is formed between the near end and the vertical plane of the nail rod, a plurality of through holes are formed in the near end, connecting holes are formed in the tail end, and a plurality of through holes are formed in the far end. According to the thighbone twist locking intramedullary nail, the mode that the nail is inserted from the top point of the greater trochanter is adopted, the nail is accurately inserted, fixation is firm, damage to the thighbone can be reduced, and the good treatment effect on intertrochanteric fractures and femoral neck fractures is achieved.
Description
Technical field
This utility model relates to technical field of medical instruments, particularly a kind of strand lock intramedullary nail for Fracture of femur location.
Background technology
To the treatment of tubulose fracture, adopt strand lock intramedullary nail to carry out clinically interior fixing more, in marrow, fixedly meet biomechanical theory, it is fixed, can make patient carry out early functional exercise and rehabilitation, can also prevent the cripetura of bone and the axial and rotation deformity of fracture.Femur strand lock intramedullary nail is used for treating fractura subtrochanterica, the dry fracture of ipsilateral femoral, imminent pathologisch Bruch, bone does not connect, but its therapeutic effect for intertrochanteric fracture of the femur, neck tuberosity fracture, simple fracture of femoral neck, supracondylar fracture is not very desirable.Therefore, need a kind of femur strand lock intramedullary nail that can better treat the above-mentioned type fracture.
Utility model content
The purpose of this utility model is to provide a kind of femur strand lock intramedullary nail, and it can improve the fixing stability of intramedullary pin and accuracy, is applicable to all kinds Fracture of femur.
For achieving the above object, this utility model is taked following technical scheme:
A femur strand lock intramedullary nail, it comprises near-end and nail bar, the two is structure as a whole and is hollow; This nail bar end is far-end; When this near-end is horizontal positioned, this nail bar and this near-end place horizontal plane are one first angle, and this near-end and this nail bar place perpendicular are one second angle, and have the physiological bending degree corresponding with human femur under loading structure;
This near-end is provided with several through holes, and end is provided with connecting hole; This far-end is provided with several through holes.
Further, described the first angle is 5 °～10 °.
Further, described the second angle is 3 °～7 °.
Further, the through hole axial direction of described near-end is different.
Further, the through hole number of described near-end is 3.
Further, the through hole number of described far-end is 2.
Further, described proximal diameter is 9-15mm.
Further, described distal diameter is 8-14mm.
The beneficial effects of the utility model are: this utility model femur strand lock intramedullary nail adopts the mode from greater trochanter summit inserting needle, and inserting needle is accurate, fixed, can reduce the injury to femur, and for intertrochanteric fracture, fracture of femoral neck has reasonable therapeutic effect.
Accompanying drawing explanation
Fig. 1 is the schematic appearance of this utility model femur strand lock intramedullary nail.
Fig. 2 is the front view of this utility model femur strand lock intramedullary nail.
Fig. 3 is the left view of this utility model femur strand lock intramedullary nail.
Fig. 4 is the top view of this utility model femur strand lock intramedullary nail.
The specific embodiment
Below only with embodiment, the enforcement aspect that this utility model is possible is described, however not in order to limit the category of this utility model institute wish protection, first give chat bright.
As shown in Figures 1 to 4, this utility model provides a kind of femur strand lock intramedullary nail, and it comprises near-end 1 and nail bar 2, and the two is structure as a whole and for hollow, conveniently insert in advance guide pin and reset, and can also before inserting intramedullary pin, expand marrow, to facilitate insertion.This nail bar end is far-end.When this near-end 1 is horizontal positioned, this nail bar 2 is one first angle a with this near-end 1 place horizontal plane, is preferably 5 °～10 °; This near-end 1 is one second angle b with these nail bar 2 place perpendiculars, is preferably 3 °～7 °, and like this, this utility model intramedullary pin has the physiological bending degree corresponding with human femur under loading structure, can be good at mating with pulp cavity.This near-end 1 is provided with several through holes 3, and end is provided with for being connected and installed the connecting hole 4 of instrument.Preferably, the axial direction of the through hole of this near-end 1 is different, for difference fracture state, can be fixed from different perspectives, to realize, resets and rebuilds two kinds of functions.These nail bar 2 ends, far-end, is also provided with several through holes 5, can implant many cross locking nails simultaneously, to increase constant intensity, prevents that fracture site from relatively rotating.
The through hole number of the near-end 1 of the present embodiment is 3, and the through hole number of nail bar 2 ends is 2, yet also can increase as required or reduce the number of through hole.
Near-end 1 diameter of the present utility model is 9-15mm, 13.5mm for example, and it has increased intramedullary pin intensity.The diameter of nail bar 2 ends is 8-14mm, for example, 8.4mm, it meets Physiological Anatomy, can make intramedullary pin insert smoothly femoral bone cavitas medullaris.Nail bar 2 end vias, near end face, make the more close articular surface in position of cross locking nail in practical operation, and intensity is higher.
This utility model femur strand lock intramedullary nail preferably adopts titanium alloy material, and it has better intensity, elasticity and biocompatibility.
In sum, this utility model femur strand lock intramedullary nail has following advantages:
1, near-end of the present utility model and main body are 3 °～7 ° angles, convenient from greater trochanter summit inserting needle;
2, nail bar of the present utility model is 5 °～10 ° anterior arch angles, can better mate with pulp cavity, can adapt to the situations such as fracture of femoral neck, intertrochanteric fracture, beautiful tuberosity fracture;
3, the through hole of nail bar of the present utility model, more near articular surface, makes the more close articular surface in position of cross locking nail, has increased constant intensity;
4, the through hole of near-end of the present utility model can be fixing from different perspectives for difference fracture, can realize and reset and rebuild two kinds of functions;
5, this utility model adopts titanium alloy material, has better intensity, elasticity and biocompatibility.
This utility model is limited with described claim.But based on this, those of ordinary skill in the art can make all obvious variations or change, all should be within main spirits of the present utility model and protection domain.
