Description
Technical field
The present invention relates to medical instruments, and in particular to a kind of femoral interlocking nail openings lead device.
Background technology
In the operative treatment of intertrochanter fracture of femur, after the completion of the reduction of the fracture, all with tuberosity tip or Pyriform sinus
Kirschner wire first carries out positioning and guiding.When clinical operation, often because of the blocking of the deviation and limbs of range estimation, and cause to position guide pin
Position and direction mistake.Solve the problems, such as this, it is necessary to design one and can ensure that will disposably be oriented to Kirschner wire is implanted in
The guider of near end of thighbone appropriate location, to avoid multiple perspective from saving operating time.
Invention content
The present invention positions inaccurate defect to solve above-mentioned guidance difficulties, provides a kind of simple in structure, and accurate positioning is fast
Speed takes convenient femoral interlocking nail openings lead device.
The present invention using following technical scheme realize,
Femoral interlocking nail openings lead device, including long arm support and the galianconism holder with the perpendicular setting of the holder, long-armed branch
It is equipped with pilot hole on frame and galianconism holder, the pilot hole of several and long-armed support vertical, galianconism branch are set on long arm support
Frame is equipped with several pilot holes vertical with galianconism, and the pilot hole is located on same section.
Preferably, the top of the long arm support and galianconism holder is equipped with the linking arm for tilting connection.
Preferably, the movable straight barrel type guide pipe being fixedly connected is equipped in the pilot hole.
Preferably, one end of the guide pipe is equipped with the shaft shoulder of limit.
Preferably, the outside for the long arm support that the guide pipe shaft shoulder in the long-armed pilot hole is located at, in galianconism pilot hole
The guide pipe shaft shoulder be located at the downside of galianconism holder.
The principle of the present invention, using the principle of two points one lines, i.e., the extended line of long-armed guide pipe and prolonging for galianconism guide pipe
Long line crosspoint with a distance from long-armed guide pipe top at 1 centimetre or so, when long-armed guide pipe withstands on the cortex of femoral shaft completely
When outside, the crosspoint of extended line is placed exactly in the center of femoral bone cavitas medullaris, using the tip of femoral bone tuberosity or Pyriform sinus as
Point of penetration, upper 1/3 pulp cavity midpoint is positioned as anchor point in femur, and guide pin is screwed in from the guide pipe at femoral bone tuberosity position
It can be realized and accurately enter upper 1/3 pulp cavity center in femur, it is simple in structure easy to implement, it is fast and accurate for positioning.

Specific implementation mode
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, the present invention provides a kind of femoral interlocking nail openings lead device, includes the holder 4 of long-armed setting
And the galianconism holder 1 with the perpendicular setting of the holder, long arm support form L-shaped support construction with galianconism holder.Long-armed branch
Pilot hole is equipped on frame and galianconism holder, pilot hole enables to Kirschner wire to pass through after placing guide pipe.Wherein long arm support
Upper setting 5 makes Kirschner wire holding and long-armed vertical pilot hole, and galianconism holder, which is equipped with, makes Kirschner wire keep vertical with galianconism
Pilot hole, the pilot hole is located on same section.
And in order to reduce the contact area of guider and tissue, while being operated convenient for personnel, the long arm support and galianconism
The top of holder is equipped with the linking arm 5 for tilting connection.
In the present embodiment, in order to further make Kirschner wire that there is better directionality in operation, it is equipped in pilot hole
Guide pipe and pilot hole are fixed when using, so that Kirschner wire is screwed in along guide pipe by the movable guide pipe being fixedly connected, long
It is replaced according to the fracture site and femur length of patient the position of arm guide pipe.
One end of guide pipe is equipped with the shaft shoulder limited with pilot hole, wherein as shown in Figure 1, the guiding in long-armed pilot hole
The pipe shaft shoulder is located at the outside of long arm support, and the guide pipe shaft shoulder in galianconism pilot hole is located at the downside of galianconism holder.It is arranged in this way
Purpose is fixed when so that Kirschner wire is screwed in guide pipe along guide pipe direction.
The application method of the present invention is as shown in Figures 4 to 7, and following Fig. 4 first selects suitable long-armed guide pipe, generally in stock
15 centimetres or so of bone tuberosity distal end, vertical femoral shaft direction screw in 2.5 millimeters of Kirschner wires of diameter so that Kirschner wire enters femur
Among dry pulp cavity in the front-back direction, such as Fig. 5.Femoral interlocking nail openings lead device is placed, long-armed guiding is placed along Kirschner wire
Pipe makes guide pipe push up always on the outside of the cortex bone of femoral shaft.Following Fig. 3 again from femoral bone tuberosity tip or Pyriform sinus direction,
2.8 millimeters of Kirschner wires of another piece of diameter are screwed in along galianconism guide pipe.If Fig. 4 is along pilot hole, screwed in femoral bone cavitas medullaris direction
20 centimetres can be completed guiding.Guider is removed, marrow is carried out out along the Kirschner wire at femoral bone tuberosity position, is implanted into intramedullary nail, it is complete
At the fixation of femoral trochanteric.
