Specific embodiment
Fig. 1 to Figure 10 is please referred to, the fracture of neck of femur in figure resets Kirschner wire positioning device, including a support frame 1, one
4, one, the first guide rail, 5, one, the second guide rail second sleeve of first sleeve 6, one of telescoping tube 3, one of a connecting tube 2, one
7, a 3rd sleeve 8.
Support frame 1 is used to provide support to connecting tube 2, which can be selected existing mobile phone self-timer support frame, in order to
Convenient to use, which can be designed to lift as needed, and specific structure can refer to the structure of existing maturation.The branch
The mode that support 1 cooperates with connecting tube 2, which can be used, to be spirally connected or is interference fitted or be clasped, preferably screw connection manner.
2 one end of connecting tube is fixed on support frame 1 using above-mentioned screw connection manner, and one end of the other end and telescoping tube 3 is at stretching
Contracting formula cooperation be telescoping tube 3 a part can in connecting tube 2 telescopic movable；Here the telescopic cooperation spoken of refers to
Telescoping tube 3 is inserted into connecting tube 2, and connecting tube 2 has telescoping tube fixing screws 21 in corresponding position, and structure is similar to bath rod
Stretching structure.Design through this structure, can the position to telescoping tube 3 adjusted in real time, ensure the accurate of surgery location.
The other end of telescoping tube 3 cooperates with first sleeve 6 at rotary moveable, and matching relationship can be therebetween using the
One sleeve fixing screws, 61 fit system, i.e. telescoping tube 3 are cooperated by the first sleeve fixing screws 61 and first sleeve 6, this
Sample can adjust the horizontal position of first sleeve 6 in real time to meet the requirement being adjusted to the angle of Kirschner wire.
First guide rail 4 and 5 top movable of the second guide rail match the both ends for sharing first sleeve 4, can directly entangle without set
Cylinder casing 41 such as Fig. 9 or in the first guide rail 4 and the second guide rail 5 top installation sleeve casing 41 such as Figure 10.The two of first sleeve 4
End is held to cooperate respectively with above-mentioned sleeve casing 41, configuration in this way, so that it may keep first sleeve 4 and the two guide rails mutual
Rotation keeps subsequent second sleeve 7,3rd sleeve 8 to be parallel with first sleeve 6 always and facilitate phase between each sleeve
To rotation.There is track in first guide rail 4 and the second guide rail 5, first sleeve 6, second sleeve 7,3rd sleeve 8 are parallel to each other
It is moveably positioned on the track between the guide rail that two are parallel to each other.Above three sleeve inner all has Kirschner wire and is passed to hole.
In order to make second sleeve 7 and 3rd sleeve 8 smooth sliding on the first guide rail 4 and the second guide rail 5, second sleeve 7, third can be made
Structure of the sleeve 8 as train wheel i.e. similar with track cooperation position design 72 structure of sliding slot.
The application method of the present apparatus is: patient keeps position of lying on one's side, and adjusts the height of support frame 1 adapt it to first
Connecting tube 2 is assembled with support frame 1 using being spirally connected, connecting tube 2 and telescoping tube 3 is used spiral shell by the needs of patient body position's height
Tipping prepares, and first sleeve 6 and telescoping tube 3 are assembled, and first sleeve 6 and the first guide rail 4 and the second guide rail 5 are assembled.
Then following steps are carried out: 1, rotating first sleeve 6 in the horizontal direction, carrying out flexible processing to telescoping tube 3 makes from first sleeve 6
The pilot pin 9 of stretching is bonded patient skin surface and makes to have an X-rayed under positive is located in neck of femur 10 at 1/3 position；Make simultaneously above-mentioned
It is parallel in 10 longitudinal axis of neck of femur that pilot pin 9 has an X-rayed lateral projection；2, second sleeve 7 can be slided up and down by sliding slot and be found in femoral shaft
Point squeezes into first piece of Kirschner wire 11 by second sleeve 7；It 3, is that basic point is rotated with pilot pin 9 and first piece of Kirschner wire 11
Suitable position determination is selected to squeeze into second piece of 11 position of Kirschner wire and squeeze into second piece of Kirschner wire 11 across second sleeve 7；4,
Third piece Kirschner wire 11 is squeezed into the taking-up of pilot pin 9 as needed；5, pass through the guiding installation hollow nail of Kirschner wire 11.
For example intertrochanteric fracture row DHS is fixed, and need to only be carried out above-mentioned 1-3 step and then be squeezed into first piece of guiding of Kirschner wire 11
Main nail is installed.
