Description
Technical field
The utility model relates to a kind of pull needle fixed frames for eccentric single armed Bone traction, belong to orthopaedics therapy field.
Background technique
Currently, often need to carry out traction therapeutic to fracture using tractor in existing fracture correction and reduction therapy, it is existing
There is drafting tool structure complex, it is cumbersome, and unreasonable structural design, the setting of tool body structure non-eccentricity can be right
Film making is operated and radiated in art to cause to stop, and is extended operating time, is increased amount of bleeding, increase operating procedure, influence to make film
Clarity and quality, clinical use effect is poor.
Summary of the invention
The purpose of this utility model is that: a kind of pull needle fixed frame for eccentric single armed Bone traction is provided, to solve
The above problem present in existing orthopaedics drafting tool.
To solve the above problems, providing a kind of pull needle fixed frame for eccentric single armed Bone traction, including the connection of " L " type
Frame, the first arc frame, the second arc frame, pedestal and regulation threaded rod, open up on the first arc frame and the second arc frame useful
In the pull needle fixation hole of fixed traction needle, pull needle fixation hole is arcuate socket, and pedestal is for the end with telescopic draw bar
It is fixedly connected, the vertex of " L " type connection frame is fixed on pedestal, and the both ends of first arc frame are connect with " L " type respectively
The both ends of frame are fixedly connected, and one end of the second arc frame extends to the vertex of " L " type connection frame, the middle part of the second arc frame with
One end of " L " type connection frame is hinged, and the threaded rod pedestal with threaded hole is fixed on the other end of " L " type connection frame, adjusts
The middle part rotation for controlling threaded rod is set in threaded rod pedestal, and is regulated and controled one end of threaded rod and one end of second arc frame and mutually cut with scissors
It connects, it is aforementioned to be fixedly connected with mode preferred weld, using the above structure, leg is bonded with the formation of the second arc frame by the first arc frame
The both ends of pull needle are individually fixed in the first arc frame by the dedicated fixing bolt of pull needle when in use by the arc groove in portion
On the pull needle fixation hole of the second arc frame.
In aforementioned pull needle fixed frame, first arc frame and the second arc frame are bar steel plate, and the first arc
The inner surface of frame and the second arc frame is smooth surface, guarantees comfort level of patient's suffering limb when contacting, and is avoided because not
With compressing and stop patient's suffering limb.
In aforementioned pull needle fixed frame, the pull needle fixation hole on the first arc frame and the second arc frame is along respective arc
The strip-shaped hole that length direction opens up.
Compared with prior art, the utility model is drawn suitable for single guide rod, in use, by the pull needle fixed frame
It is fixed on the end of telescopic draw bar, there are two types of application methods, one is fixation connects respectively by the both ends of telescopic draw bar
It is connected to the pull needle fixed frame and pelvic traction pincers, forms a kind of eccentric single armed Bone traction dress suitable for femur correlation fracture
It sets, another kind is to be respectively fixedly connected with the pull needle fixed frame at the both ends of telescopic draw bar, forms one kind and is suitable for
The eccentric single armed bone distraction apparatus of shin bone, humerus grade ulna and radius correlation fracture, flexible and convenient to use, modularization assembles, device knot
Structure and operation are all more simple；Single guide rod eccentric structure is not easy to cause to stop to operation and according to taking the photograph X-ray, the shooting quality of raising and
Clarity.The radiation to patient can also be reduced, existing traction device needs assistant to assist holding flexible when patient shines X-ray
Formula draw bar is held in place, and the device holds or draws without assistant after drawing in art, and operator all removes
Out, operator will not be caused to radiate；The device is fixed on distal femur in one end when femur correlation is fractured and used, separately
One end is fixed at pelvis, more preferable relative to skin traction traction effect, compared to using perineum lever etc., additionally it is possible to avoid injuring
At patient's perineum；Pull needle fixed rack structure bionic design, modularization described in the device assemble, ingenious in design, simply and more
To be practical, radian is adjustable, and arc groove size, optimization mechanism setting, using more can be adjusted according to patient legs' thickness situation
It is simple and efficient.
Meanwhile the pull needle fixed frame bias designs, structure optimization avoids draft arm from being located at front, in x-ray and art
Operation impacts；Bionic design, unique design curved plate and L-type steel plate combination, inside form arc and suffering limb physiology
Dissection is consistent, and radian is adjustable, keeps matching good；The pull needle fixed frame is opening regulating structure, can be realized fine needle and fixes,
Immobilization of the wounded limb opening width and pull needle tension can be adjusted, to adapt to the fixation of different size suffering limbs；Pull needle fixation hole is
Arc aperture can allow for limbs and pull needle to rotate, even if pull needle trains off, can also be transposed by rotation；Each component
Between be assembly type structure, can be realized and arbitrarily assemble, it is easy to operate, just with storage and preservation.
