Bottom is equipped with anti-slop serrations, and anti-slop serrations can be such that the bottom of interchangeable guide sleeve more stably compresses to be located in soft group of patient's fracture site
Knit or bone face on, prevent the guide sleeve relative to it is designed enter pin mark shift, which improves pierce Kirschner wire
When enter the accuracy of pin mark.
(6), the minimally invasive pressurization fixed guider of adjustable fracture of the invention and its application method, devise two curved bars,
Curved bar is designed to move up and down and lock, can be further improved the accuracy for going out pin mark of Kirschner wire, and is adapted to different
The different both injured bones fracture operation of the shape thickness of patient's different parts.
(7), the minimally invasive pressurization fixed guider of adjustable fracture of the invention and its application method, devise two curved bars and
Two lengthening curved bars can substantially meet the needs of clinical common fracture operation, and the scope of application is wider, it can only use two small
Range curved bar, to adapt to the lesser both injured bones of diameter；The lengthening curved bar of two wide ranges can also be only used, with adapt to diameter compared with
Big both injured bones；Can also use a small-range curved bar and a wide range lengthening curved bar, with adapt to one end diameter it is smaller,
The both injured bones that the other end is relatively large in diameter.
(8), the minimally invasive pressurization fixed guider of adjustable fracture of the invention and its application method, the adjusting knob is set
Be calculated as cylindrical body and circumferential outer surface and be equipped with annular knurl anti-skid chequer to screw, the curved bar adjusting nut be designed as it is quincunx so as to
It screws.
(9), the minimally invasive pressurization fixed guider of adjustable fracture of the invention and its application method, multi-purpose content, itself is just
Have the function of loaded reset, eliminate the operation for reinstalling a set of resetting apparatus, improves procedure efficiency and operation is accurate
Degree, reduces the workload of doctor and the pain of patient；The circumferential outer surface of the adjusting knob is provided with pressurization rotating hole, is used for
Insertion bar tool carries out rotating the adjusting knob, and when due to loaded reset, the reset resistance being subject to is larger, and use is longer
Bar tool is more laborsaving, and is not necessarily to specific purpose tool, and diameter is no more than the hard pole of the pressurization rotation bore dia, all may be used
To use.
(10), the minimally invasive pressurization fixed guider of adjustable fracture of the invention and its application method are provided with spring-loaded plunger
And spherical groove, when foreign matter grazing to adjusting knob, the active force of generation is smaller, ofer short duration, is not enough to that the spring can be overcome
The resistance that the scalable top of plunger is skidded off from the spherical groove, therefore the adjusting knob will not be made to rotate, thus really
It has protected and has adjusted the stabilizations of two guide sleeves of spacing and do not deviate.

The axial line in hole 18 is parallel with the plane that two 4 axial lines of guide sleeve are formed.17 are equipped with rotational pin on the rotating block
(not shown), rotational pin are that a straight-bar (not shown) passes through the rotation hole 18.The rotation hole 18 can be passed through only
Wear rotating block accommodating 16 1 side walls of through-hole, 17 are equipped with a rotational pin and (do not show in figure on the corresponding rotating block
Out)；The rotation hole 18 can also accommodate the opposite two side walls of through-hole 16 through the rotating block, correspond on the rotating block
17 are equipped with two rotational pin (not shown)s.Referring to Figure 15, Figure 16, the rotating block 17 can be around the rotation hole 18
Axial line rotation.The minimally invasive pressurization fixed guider of the adjustable fracture of the present embodiment further includes intermediate guide sleeve 7, for to
The third root Kirschner wire guiding pierced, the rotating block 17 are equipped with intermediate guide sleeve and wear through-hole 171, the intermediate guide sleeve
7, which are interspersed in the intermediate guide sleeve, wears in through-hole 171, and the top of the intermediate guide sleeve 7 is equipped with blocking portion 71, for preventing
The intermediate guide sleeve 7 is worn in through-hole 171 from the intermediate guide sleeve to fall off, blocking portion 71 be preferably step surface, it is described in
Between the bottom of guide sleeve 7 be equipped with anti-slop serrations, anti-slop serrations can be such that the bottom of the intermediate guide sleeve 7 preferably compresses to be located in patient
On the soft tissue of fracture site or bone face, prevents the intermediate guide sleeve 7 from entering pin mark relative to designed Kirschner wire and occur partially
It moves.Preferably, the total length of the intermediate guide sleeve 7 is 100mm, the internal diameter specification of the intermediate guide sleeve 7 be 0.9mm,
Tetra- kinds of specifications of 1.2mm, 1.5mm, 2.0mm accordingly select the Kirschner wire of these four specifications, to meet clinical most common reality
Border needs.
When work, after the Kirschner wire parallel to two pierces, according to actual operation needs, it is determined whether enable intermediate
Guide sleeve 7.When determination needs to pierce third root Kirschner wire, the intermediate guide sleeve 7 of one of above four kinds of specifications is first chosen；
The intermediate guide sleeve 7 is worn into through-hole 171 across the intermediate guide sleeve again, makes the 7 skidproof bottom tooth of intermediate guide sleeve
It is resisted against on the soft tissue or bone face of patient's fracture site；Then the intermediate guide sleeve 7 is pinched about the rotation hole
18 rotations, to make 7 bottom of intermediate guide sleeve slide along the soft tissue of patient's fracture site or bone face, until being targeted by
What is determined enters pin mark；Then the 7 skidproof bottom tooth of intermediate guide sleeve is made to compress the soft tissue for being located in patient's fracture site
Or on bone face, third root Kirschner wire is finally pierced.
The intermediate guide sleeve 7 added is used for third root Kirschner wire guiding is pierced, and meeting clinically used reality needs
It wants, it is often more important that, referring to Figure 14, Figure 15, the Kirschner wire parallel to two enables the intermediate guide sleeve 7 after piercing,
The intermediate guide sleeve 7 and other two guide sleeve 4 fixed form stable triangular structure, and the centre is led
The end face that the adjusting screw rod 31 can only be parallel to set 7, which is done, angularly to be swung, therefore is piercing third root Kirschner wire
In the process, even if by electric drill or the vibration influence of other external force, the intermediate guide sleeve 7 it is opposite enter pin mark it is also very stable, no
Easily shift.
