Abstract
The invention belongs to treat intercondylar fracture of femur, fracture of tibial plateau, intercondylar fracture of humerus or the fixator for fracture reduction or method of other similar positions；Its special equipment technical field discloses a kind of intercondylar reset and threads a needle pincers and its application method, and pliers head end is sharp, it is held convenient for being pierced into sclerotin through skin, bulb provides constraints, and threads a needle hole in two sides through bulb, because general Kirschner wire is 2.0mm or 2.5mm, hole is eccentric；Shank has active pin, and side is welded with threaded telescopic rod, and the other side is the nut that can be tightened or unscrew.Kirschner wire is accurately penetrated when the present invention is directed to obtain satisfied reset, ideal fixed effect is obtained convenient for fixed in time, reduces the damage of number of operations and surface texture, it reduces and resets clamp number repeatedly, shorten operating time, improve procedure efficiency, operates with safe and reliable.
Description
Technical field
It is fixed the invention belongs to treat femoral intercondylar, tibial plateau, humeral intercondy or other similar position reduction of the fracture
Device or method；Its special equipment technical field, more particularly to a kind of intercondylar reset are threaded a needle pincers and its application method.
Background technique
Currently, the prior art commonly used in the trade is such thatIt there is no a kind of reduction forceps that can be exclusively used in condyles fracture.Especially
Be adult fracture of the humeral condyle, fracture of the femoral condyle, these three positions of fracture of tibial plateau fracture account for very big ratio in fracture
Example does not still include the similar fracture in other positions.Current existing some general reduction forceps are borrowed, are often mismatched, or i.e.
Make to obtain satisfied reset sometimes, but be another location again when guiding needle, C arm is had an X-rayed always when further completing fixed
Owe satisfaction.It i.e. at optimal reset position, needs to move position of threading a needle, thus cannot accurately fix.
In conclusion problem of the existing technology is:
(1) without dedicated grips pincers
(2) inserting needle, which moves to lose optimum position and fix, causes position to owe satisfaction
(3) position of existing grips pincers and needs fixation mismatches
Solve the difficulty and meaning of above-mentioned technical problem:
The dedicated grips pincers of this instrument system condyles fracture, can when fracture obtains optimum position fixed promptly and accurately complete
At, it is accurately fixed in ideal position, it is final to obtain all satisfied effect of doctor and patient.
Summary of the invention
In view of the problems of the existing technology, it threads a needle pincers and its application method the present invention provides a kind of intercondylar reset.
The pincers the invention is realized in this way a kind of intercondylar reset is threaded a needle, the intercondylar pincers of threading a needle that reset are provided with
It is gradually tapered after pliers end bulb or fusiformis shape；
It is provided on pliers bulb through bulb and wears Kirschner wire fixation hole, hole is eccentric；
Kirschner wire fixation bore dia is worn greater than 2.0mm or is greater than 2.5mm；
Shank has turning joint；
Side is welded with threaded telescopic rod, and the other side is the nut that can be tightened or unscrew；
The pincers length can be divided to 30CM, 40CM two kinds of specifications.Pincers point arrives pivot pin: pivot pin to welding screw rod: welding screw rod to end
End=1:1:1.3, that is, 30CM specification is 9,9,12；40CM specification is 12,12,16.
Another object of the present invention is to provide a kind of intercondylar application method for resetting pincers of threading a needle, the intercondylar resets
The condyles that the application method of pincers of threading a needle is fractured by the tip clamping clamped, Kirschner wire are pierced into cortical bone by Kirschner wire fixation hole and consolidate
It is fixed.
In conclusion advantages of the present invention and good effect are as follows:The dedicated grips pincers of this instrument system condyles fracture, Ke Yi
Fracture obtains fixed completion promptly and accurately when optimum position, accurately fixes in ideal position, and final acquisition doctor and patient is all full
The effect of meaning.
Detailed description of the invention
Fig. 1 is that intercondylar reset provided in an embodiment of the present invention is threaded a needle wrench structure schematic diagram；
In figure: 1, Kirschner wire fixation hole；2, pliers head；3, pivot pin；4, telescopic rod；5, pliers handle.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to
Limit the present invention.
As shown in Figure 1, it is provided in an embodiment of the present invention it is intercondylar reset thread a needle pincers include: Kirschner wire fixation hole 1, pliers head 2,
Pivot pin 3, telescopic rod 4, pliers handle 5.
2 top of pliers head is provided with Kirschner wire fixation hole 1；5 top of pliers handle is connected with pliers head 2；5 lower weld of pliers handle
There is telescopic rod, by twisting nut come hypertonic；2 pliers handles 5 are connected by pivot pin.
As a preferred embodiment, 2 length of pliers head is 9cm.
As a preferred embodiment, the distance of the telescopic rod 4 to pivot pin 3 is 9cm.
As a preferred embodiment, it is 13cm that the telescopic rod 4, which arrives 5 threshold value of pliers handle,.
As a preferred embodiment, the length of the telescopic rod 4 is 9cm.
As a preferred embodiment, described to wear Kirschner wire fixation bore dia greater than 2.0mm or be greater than 2.5mm.
The working principle of the invention: it in therapeutic process, first passes through pliers head 2 and clamps condyles, Kirschner wire passes through Kirschner wire
Fixation hole 1 penetrates sclerotin and fixation.In therapeutic process, because of the fixation of pliers, condyles movement, after fixed, Kirschner wire are avoided
It is implanted into along Kirschner wire fixation hole 1, shortens operating time, reduce the personnel to operate, greatly reduced the irradiation of C arm, improve operation
Efficiency.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
