Abstract
The invention discloses a kind of novel femoral interlocking nail, including proximally and distally：The proximal end includes four lock holes, from top to bottom the lock hole of lock hole, two lock holes locked obliquely and lateral locking to lock obliquely；The locking direction of the lock hole of the lateral locking and other three lock holes is not in the same plane；The distal end includes at least two lock holes for being located at Different Plane.The invention has the advantages that compared to common femoral interlocking nail, which moves down the nethermost lateral locking hole in proximal end, can be in the fracture that a fixed part relatively crushes, and intramedullary nail is fixed using the nail of proximal end three.If proximal femoral neck is fixed difficult simultaneously, the fixed form of one piece of oblique neck of femur locking nail, one piece of lateral pinning can be used, make surgical selection more, improve postoperative biomechanical strength.
Description
Technical field
The present invention relates to a kind of novel femoral interlocking nails, and the novel of selection is locked with various more particularly, to a kind of
Femoral interlocking nail.
Background technology
The proximal end nail hole of existing femoral interlocking nail is designed for Bidirectional locking system：Both the proximal end locking for having met shaft fracture is set
Meter (lateral locking is followed closely and oblique locking nail)；In addition it is exactly reconstruction nail design (the two pieces of lockings for meeting subtrochanteric fracture between tuberosity
It follows closely to wear neck of femur).Distal end nail hole is designed for the planar system of single transverse.But proximal end design the shortcomings that be this two-way two
Set system can not intersect during nail is put, and can only select a wherein set of system.The shortcomings that remote design, is distal femur condyle
Portion's enlargement makes intramedullary nail be difficult to effective fixation.
Invention content
It is an object of the invention to overcome the deficiency of the prior art, a kind of novel femoral interlocking nail is provided.
The first technical solution is used by the present invention solves its technical problem：
A kind of novel femoral interlocking nail, including proximally and distally：It is characterized in that：The distal end includes at least two
In the lock hole of Different Plane.
In a further preferred embodiment, there are two the lock holes, one of lock hole is lateral locking, another lock
It is different from the locking direction of the lock hole of the lateral locking to determine hole.
There are three the lock holes, and two of which lock hole is lateral locking, another lock hole is laterally locked with this two
The locking direction of fixed lock hole is not in same plane, and the lock hole is located between the lock hole of two lateral lockings.
In a further preferred embodiment, there are four the lock holes, two of which lock hole is lateral locking；Another two is locked
Hole is determined with the locking direction of the lock hole of two lateral lockings not in same plane, and the locking direction of two lock holes does not exist
Same plane, two lock holes are located between the lock hole of two lateral lockings.
In a further preferred embodiment, the proximal end includes four lock holes, the from top to bottom locking to lock obliquely
The lock hole in hole, two lock holes locked obliquely and lateral locking；The lock hole of the lateral locking and other three locks
Determine the locking direction in hole not in the same plane.
In a further preferred embodiment, the lock hole of the lateral locking and the distance of the lock hole with being positioned above are big
In 2.5cm.
The first technical solution is used by the present invention solves its technical problem：
A kind of novel femoral interlocking nail, including proximally and distally：It is characterized in that：The proximal end includes four lockings
Hole, the from top to bottom lock hole of lock hole, two lock holes locked obliquely and lateral locking to lock obliquely；It is described
The locking direction of the lock hole of lateral locking and other three lock holes is not in the same plane；The distal end includes at least two
A lock hole positioned at Different Plane.
In a further preferred embodiment, there are four the lock holes of the distal end, two of which lock hole is lateral locking；Separately
The locking direction of the lock hole of two lock holes and two lateral lockings is not in same plane, the locking side of two lock holes
To in same plane, which is not located between the lock hole of two lateral lockings.
The invention has the advantages that the nethermost lateral locking hole in proximal end is moved down, it can be in a part of ratio of fixation
Compared with crushing fracture when, intramedullary nail using proximal end three nail fix.If proximal femoral neck is fixed difficult simultaneously, one piece can be used tiltedly
To the fixed form of neck of femur locking nail, one piece of lateral pinning, make surgical selection more；；In two lateral locking holes of distal end
Between more two lock holes for being located at Different Plane of setting, far-end locking will be made more secured by multilevel fixed form；
The present invention can provide a variety of lock modes on same intramedullary nail, postoperative biomechanical strength be improved, conducive to surgical effect
With the recovery of patient.
The present invention is described in further detail with reference to the accompanying drawings and embodiments；But a kind of novel femur of the present invention
Intramedullary nail is not limited to embodiment.
Description of the drawings
Fig. 1 is the structure diagram of presently preferred embodiments of the present invention.
Fig. 2 is the sectional view of Fig. 1.
Specific embodiment
Embodiment, ginseng are seen figure 1 and figure 2, a kind of novel femoral interlocking nail of the invention, including distal end 100 and closely
End 200：The lock hole of the distal end 100 from top to bottom there are four, two of which lock hole 110 and 120 be lateral locking；Another two
The locking direction of the lock hole 110 and 120 of a lock hole 130 and 140 and two lateral lockings is not in same plane；It and should
The locking direction of two lock holes 130 and 140 is different, and locking direction intersects in the projection of horizontal plane；This two
Lock hole 130 and 140 is located between the lock hole 110 and 120 of two lateral lockings.The proximal end 200 includes four lockings
Hole is from top to bottom 210, two lock holes locked obliquely 220 and 230 of lock hole for locking obliquely and lateral locking
Lock hole 240；The locking direction of the lock hole 240 of the lateral locking and other three lock holes 210,220 and 230 is not same
In one plane.
Compared to common femoral interlocking nail, which moves down the nethermost lateral locking hole in proximal end, can be solid
During the fracture that a fixed part relatively crushes, intramedullary nail is fixed using the nail of proximal end three.If proximal femoral neck is fixed difficult simultaneously, can
Using the fixed form of one piece of oblique neck of femur locking nail, one piece of lateral pinning, make surgical selection more；Two horizontal strokes in distal end
More two lock holes for being located at Different Plane of setting, will make far-end locking more by multilevel fixed form between lock hole
Add securely；The present invention can provide a variety of lock modes on same intramedullary nail, postoperative biomechanical strength be improved, conducive to hand
Art effect and the recovery of patient.
Above-described embodiment is only used for a kind of novel femoral interlocking nail further illustrated the present invention, but not office of the invention
Be limited to embodiment, any simple modification that every technical spirit according to the present invention makees above example, equivalent variations with
Modification, each falls in the protection domain of technical solution of the present invention.
