Description
Technical field
It the utility model is related to orthopaedic medical treatment assistive device, and in particular to a kind of reduction of the fracture device.
Background technology
Fracture is clinical common disease, to can not expectant treatment situation, operative treatment can only be used.It is clinically bright to having
The most frequently used treatment method of the fracture of aobvious displacement is fracture open reduction steel plate screw internal fixation, and skin soft tissue is cut
Afterwards, exposure fracture site, gives bone plate and screw fixation after reset.It can be led for simple fracture by pulling
Draw, rotate the methods of flexing, convolution of folding top and reset, plate fixation is given again after Kirschner wire is temporarily fixed；Complicated fracture is then
Need to rely on reduction instrument auxiliary reset, such as bone holding forcep, reduction forceps, elevator, must be fixed temporarily with Kirschner wire after reset, thoroughly
After confirming fracture reduction to line, plate fixation can be further given.
Fractured for complexity, it is necessary to using reduction instrument, when patient operate by bone holding forcep etc., it is necessary to remain and answer
Position action, adjusts fracture, direction and angle, it tends to be difficult to once reset successfully, need to give Kirschner wire interim after reset repeatedly
Fixed fracture site, and it is sometimes also not very firm after fixing, it may appear that shift again.To fracture site pulverizer, Kirschner wire
It is often difficult to fix.Even if Kirschner wire fixation is good, the squeezing into for placement and screw to later stage bone plate also can often cause to stop.
And in the case of fracture is with Cranial defect, it is more complicated during reset and be difficult to operate.Reseting procedure often consumes a large amount of manpowers,
The most of the time of operation is occupied, directly affects being smoothed out for operation.The whether smooth of reseting procedure is related to operation
Time length and success or failure, complicated comminuted fracture or with Cranial defect person resets more difficult, and needs to be maintained after resetting pair
Position could carry out next step operation to line relation.Reset the design and application of aid, efficiency and success or failure meaning to operation
It is great.
Utility model content
Purpose of utility model：The problem of existing for prior art, the utility model provide a kind of reduction of the fracture device；This is multiple
Position device can be maintained the stable state of fracture both ends pairing, solve the problems, such as to continue to keep homing action during patient's reset,
Physical demands is reduced, improves procedure efficiency, shortens operating time；Simultaneously do not need the interim fixation of Kirschner wire will not cause to block and
Influence transparent effect and do not interfere with the placement of bone plate and squeezing into for screw.
Technical scheme：To achieve these goals, such as a kind of reduction of the fracture device described in the utility model, including first holds
Bone forceps and the second bone holding forcep, the first bone holding forcep side are welded with cylindrical type connecting rod, the second bone holding forcep and the first bone holding forcep pair
Side is welded with the cylindrical type connecting rod with round end, and cylindrical type connecting rod is connected with the cylindrical type connecting rod with round end by hollow sleeve；In
The first fixing device is provided with empty set pipe and the second fixing device is used to distinguish fixed cylinder type connecting rod and the cylinder with round end
Type connecting rod.
Two bone holding forcep of the utility model are respectively welded the not restoring link of same-action and connected by hollow sleeve, one
For the movable disengaging of side cylindrical type connecting rod to adjust the alignment of fracture site, cylindrical type connecting rod of the opposite side with round end can be universal
Rotating to adjust the relative angle of fracture site and direction, hollow sleeve both sides are respectively equipped with fixing device, fix two connecting rods,
The stable state of fracture both ends pairing is maintained so as to realize.
Preferably, described hollow sleeve one end is circular arc mortar cup, the round end of the cylindrical type connecting rod with round end is caught in circular arc
In mortar cup；Circular arc mortar cup is provided with, the cylindrical type connecting rod with round end can easily facilitate adjustment bone by universal rotational in hollow sleeve
Roll over the angle and direction at end.
Wherein, the circular arc mortar cup upper and lower ends are provided with two the second fixing devices；
The lock banking stop with the welding of the second fixing device, the radian of lock banking stop and the cylinder with round end are provided with circular arc mortar cup
The round end radian of type connecting rod is consistent.When two the second fixing devices are screwed into, the second of the locking limited step of circular arc mortar cup upper and lower ends
Fixing device can pressurize to the round end in cylindrical type connecting rod and circular arc mortar cup.
Preferably, the internal diameter of the hollow sleeve other end is consistent with cylindrical type connecting rod external diameter so that cylindrical type connecting rod
Disengaging activity in hollow sleeve is more smooth, with the alignment of adjustment fracture.
Preferably, first fixing device is located at hollow sleeve close to one end of cylindrical type connecting rod.
Preferably, first fixing device and the second fixing device are screw.
Operation principle：After exposure fracture site, the bone holding forcep of this restorer both sides first and the second bone holding forcep are given to clamp respectively
Fracture both ends, latch is fixed after clamping.Both hands hold bone holding forcep respectively, are lived by disengaging of the cylindrical type connecting rod in hollow sleeve
The dynamic pulling realized in resetting, drawing-in motion pass through cylindrical type connecting rod its head end with round end to adjust the contraposition of fracture site
Universal rotational in hollow sleeve is to adjust the angle and direction of fracture site, by the reduction of the fracture.After the reduction of the fracture, tighten
Second fixing device of locking limited step above and below the first fixing device and circular arc mortar cup of the nearly cylindrical type connecting rod side of hollow sleeve, i.e.,
Two connecting rods can be fixed, it is good to line to confirm whether fracture site aligns under C arms X-ray machine perspective, as position is not good enough, then unclamps
Screw and lock banking stop, reset again, as fracture is good, then accuses and reset successfully, can carry out next step operative treatment.
Beneficial effect：Compared with prior art, the utility model has the following advantages that：
1st, the utility model can fix fracture site respectively by two bone holding forcep, and cylindrical type connecting rod passes through in hollow sleeve
Activity disengaging in pipe is to adjust the alignment of fracture, the universal rotational with round end connecting rod by its head end in hollow sleeve
To adjust the angle and direction of fracture end, after the reduction of the fracture, the first fixing device and the second fixing device are tightened, you can fixed
Two connecting rods, the stable state of fracture both ends pairing is maintained so as to realize, both homing action was remained without patient, and reduced
Physical demands, procedure efficiency is improved, shorten operating time.
2nd, it is not required to fix fracture site progress Kirschner wire temporarily using the reduction of the fracture device, because Kirschner wire fixation is not
Very firmly, and fracture site can be damaged, it influences transparent effect, and influences placement and the screw of later stage bone plate
Squeeze into；Because not needing Kirschner wire to fix temporarily, had an X-rayed after reset under C arm X-ray machines, will not cause to block and influence perspective effect
Fruit；After resetting satisfaction using the reduction of the fracture device simultaneously, it can fix, will not be caused because of kirschner directly in row fracture site bone plate
The interim fixation of pin and influence the placement of bone plate and squeezing into for screw.
If the 3, having Cranial defect using the reduction of the fracture device fracture site, Cranial defect region can be reserved when resetting, so as to
Bone grafting.
Brief description of the drawings
