Specific embodiment
Embodiment: a kind of adjustable fracture reduction device, including feeding part, reduction of the fracture bar 1 and bone conduction needle 2 are squeezed, it is described
Squeeze the soft tissue formation soft tissue channel that feeding part can pierce through and expand human fracture's portion faces, reduction of the fracture bar 1 one
End can be inserted in soft tissue channel and reach fracture, and it is axial in the presence of setting that reduction of the fracture bar 1 is equipped at least two
The axial through bore 6 of angle, at least two correspondences of bone conduction needle 2 are arranged in the axial through bore 6, and 2 one end of bone conduction needle is tip, bone
The tip of 2 one end of guide pin can stretch out reduction of the fracture bar 1 and be pierced into the bone block at human fracture position, bone conduction needle 2 and fracture
1 other end of release link is exposed to set distance on the outside of human body soft tissue, and when human body is fractured, first passing through extruding feeding part will cover
It covers the soft tissue on fracture site surface to pierce through and expand to form a soft tissue channel, it is soft that reduction of the fracture part is then inserted into this
In anatomic passages, make itself and fracture site face, each axial through bore 6 then bone conduction needle 2 being inserted on reduction of the fracture bar 1
It is interior, and it is inserted into the tip of 2 one end of bone conduction needle in the bone block of fracture site, keep the bone block of each bone conduction needle 2 and fracture site solid
Surely it is connected to form one, reduction of the fracture bar 1 and bone conduction needle 2 is operated at this time, by fracture site by way of pushing away, drawing and rotate
Bone block resets, and then fracture site can be fixed, the utility model can be realized any angle of fracture site bone block
Adjustment resets, and without opening up big notch, each bone conduction needle 2 forms stable triangular structure with bone block fixation, and bone block is not
It can be detached from reseting procedure with bone conduction needle 2, guarantee that bone block resets in place, bone conduction needle 2 can select to have according to fracture site size
The size of body, such as 1mm, 2mm, 3mm, 4mm the utility model can be realized the minimally invasive accurate reduction of the fracture, operate without undisguised,
It is small to patient body wound, restore fast after reduction of the fracture treatment.
It is additionally provided with external member 3, the extruding feeding part and reduction of the fracture bar 1 can be inserted in the external member 3, and external member 3 can be with
It realizes the guiding role for squeezing feeding part and reduction of the fracture bar 1, when operation, external member 3 is first directed at fracture site, then will squeeze
Feeding part, which is inserted into external member 3 and applies pressure to extruding feeding part, to be made it puncture soft tissue and forms the soft tissue channel of expansion, so
It extracts afterwards and squeezes feeding part, external member 3 is maintained in soft tissue channel, is inserted into reduction of the fracture bar 1, guarantees that reduction of the fracture bar 1 is quick
It is inserted into soft tissue channel, soft tissue channel is supported by external member 3, avoids retract soft tissue.
The extruding feeding part includes the first pressure ram 4, which is tip, is realized by tip soft
Tissue punctures, and 4 diameter of the first pressure ram is gradually increased, and realization first punctures further expansion.
The extruding feeding part further includes the second pressure ram 5, which is blunt nosed, the first pressure ram 4 general
Soft tissue is punctured and is extracted after tentatively expanding, and is inserted into the second pressure ram 5, and the blunt nosed of the second pressure ram 5 will be pierced by the first pressure ram 4
The broken and soft tissue channel further expansion tentatively expanded is convenient for the insertion of subsequent reduction of the fracture bar 1 to specified size.
The tip surface of told 2 one end of bone conduction needle forms external thread structure, and external thread mechanism and its tip cooperatively form certainly
Bolt structure is attacked, which pierces in fracture site bone block convenient for bone conduction needle 2, is firmly combined with the bone block of fracture site, nothing
By being to push and pull or rotate, bone conduction needle 2 will not be all detached from bone block.
Axial through bore 6 is two on the reduction of the fracture bar 1, and two axial through bore 6 are along 1 axisymmetrical of reduction of the fracture bar
Distribution, and each axial through bore 6 and the axial angle of reduction of the fracture bar 1 are 10 °, are also possible to more, such as three or
Four etc., each axial through bore 6 can not also be distributed along 1 axisymmetrical of reduction of the fracture bar, as long as forming angle, angle
It can be other numerical value, be matched with fracture site and fracture size.
Each 6 axis of axial through bore is to intersect with the plane that 1 axis of reduction of the fracture bar is formed on the reduction of the fracture bar 1
Face, bone conduction needle 2 and bone block form three-dimensional intersection, and connection is stronger, and operation is more smoothly.
It is additionally provided with hollow bone drill 7 and spicule 8, which is hollow tubular structures, and 7 one end of hollow bone drill forms sword
Portion, 8 one end of spicule are tip, and 8 one end of spicule can be inserted in the bone in 7 other end of hollow bone drill and being pierced into hollow bone drill 7
In matter, for fracture site not in bone surface, such as at bones or the bone back side, then hollow bone drill 7 is inserted into soft group
It knits in channel, applies axial compressive force or rotation torque to hollow bone drill 7, then it is logical to form a sclerotin on bone for hollow bone drill 7
Road, which enters the hollow interior of hollow bone drill 7, after sclerotin channel reaches fracture site, stops boring
Spicule 8 is inserted into from 7 other end of hollow bone drill and extend into sclerotin, sclerotin is pegged simultaneously by hole, make it is swollen outside sclerotin, with sky
Sclerotin can be taken out together in company with hollow bone drill 7 at this time, form an arrival bone on bone by the tensioning of 7 inner sidewall of heart bone drill
Reduction of the fracture bar 1, is inserted into sclerotin channel, and be inserted into 8 pairs of fracture bone blocks of spicule and grasp by the sclerotin channel of folding part position at this time
It resets, after bone block reset the sclerotin of taking-up is filled out into go back to sclerotin channel again, realized in bone by hollow bone drill 7
It avoids opening at soft tissue, nerve and the more bone back side of blood vessel convenient for the implementation of operation with the reset of bone back side bone block
Hole is conducive to the safety for improving operation.
The extruding feeding part and 7 other end of hollow bone drill are respectively equipped with handle 9, by the gripping of handle 9, convenient for crowded
It is pressed into the operation and force to part and hollow bone drill 7.
Another end surfaces of the reduction of the fracture bar 1 are equipped with non-slip texture.
