Abstract
The utility model discloses a femoral dynamic condyle positioning device which comprises a first scale and a second scale which are movably connected; and bulged teeth are arranged at one ends of the first scale and the second scale respectively. The femoral dynamic condyle positioning device provided by the utility model can enable the positioning to be precision and the operation to be simplified and minimally invasive, and avoid complications. When the femoral dynamic condyle positioning device is in use, the positioning can be performed outside joints, so that the opportunity that the joints are exposed is reduced, the infection probability and the wound are further reduced, the structure of a normal bone is not damaged, and the femoral dynamic condyle can be fixed firmly.
Description
Technical field
This utility model relates to a kind of limb rehabilitating auxiliary appliance, particularly a kind of femoral power condyle positioner easy to use, simple in structure.
Background technology
Today that traffic is flourishing day by day, Methods for Distal Femoral Fractures patient is more and more.Methods for Distal Femoral Fractures action edge condyle (DCS) internal fixation has reached common recognition, but because of do not have accurate localizer often cause locating inaccurate, thereby the severe complication that causes (having changed the normal femoral shaft line of force, internal fixation inefficacy, ankylosis etc.) is also more and more many.
Current, during state, inside and outside orthopedist row femoral shaft far-end fracture DCS (power condyle system) internal fixation, mainly in the art rely on subjective judgment and locate, very coarse, fuzzy.Usually cause the steel plate part of DCS well to attach mutually in the art with femoral shaft, the clinician is a head it off, often condyle of femur outside cortex is removed, thereby this will cause the intensity of bone and strength of fixation reduction to make DCS easily loosening undoubtedly, the time that postoperative has to postpone to bear a heavy burden and delay feature is taken exercise, and lost due function of joint.
The utility model content
The utility model purpose: technical problem to be solved in the utility model is at the deficiencies in the prior art, and a kind of femoral power condyle positioner is provided.
In order to solve the problems of the technologies described above, the utility model discloses a kind of femoral power condyle positioner, comprise first scale and second scale, and flexibly connect between first scale and second scale;
One end of described first scale and second scale is respectively arranged with the teeth of protrusion.
In this utility model, described first scale is provided with chute, and second scale is provided with slidiing pin and slides along chute in chute.
In this utility model, described teeth are vertical to be arranged on first scale and second scale.
In this utility model, described teeth are two.
In this utility model, described first scale is provided with identical scale mark with second scale.
Beneficial effect: this utility model femoral power condyle positioner can make the location accurately, simplified control, Wicresoft, avoid complication.During use, but thereby the joint outside fix reduces the chance that exposes the joint, and further reduce infection probability and wound, and do not destroyed the normal bone structure, can make the fixation of femoral power condyle.Postoperative can carry out early functional exercise, thus joint function recovery degree height, for extensive patients provides a kind of new selection.
Description of drawings
Below in conjunction with the drawings and specific embodiments this utility model is done further to specify, above-mentioned and/or otherwise advantage of the present utility model will become apparent.
Be illustrated as this utility model structural representation.
The specific embodiment
As shown in the figure, the utility model discloses a kind of femoral power condyle positioner, comprise first scale 1 and second scale 2, and flexibly connect between first scale and second scale; One end of described first scale and second scale is respectively arranged with the teeth 3 of protrusion.Described first scale is provided with chute 4, the second scales and is provided with slidiing pin 5, and slidiing pin slides along chute in chute.Described teeth are vertical to be arranged on first scale and second scale.Described teeth are two.First scale 1 is provided with identical scale mark 6 with second scale 2.
Embodiment 1
Design two mutually perpendicular scales with identical scale mark 6, one of them scale 2 can vertically slide in the chute 4 of another scale 1, and an end of two scales respectively with two vertical teeth 3 in case hook the femoral lateral condyle distal-most end articular surface and the back facies artieularis malleolaris.Read the scale value of hooking femoral lateral condyle distal-most end articular surface, at the 2cm place vertically to this scale of front slide, 1/3 place in condyle total length preceding before and after the measured femur of another scale 1.Be the best herein and lead penetration (being bearing pin 5 positions), be inserted in 95 degree localizers, and make guide pin be parallel to kneecap thigh and knee joint surface, application femoral power condyle location that so just can be accurately errorless.
According to condyle length before and after the distal femur, the hollow (2mm internal diameter) that the wide 4mm of design 2cm is thick also is with graduated scale on the knee joint model, and end is with two vertical little teeth; Design that the wide 2mm of another 2cm is thick to be with graduated scale, can insert previous scale and can vertically slide (end also is with two vertical little teeth), so that realize two-dimensional localization; Should there be the hollow out (1.5mm is wide) of same size on another scale surface, realizes three-dimensional localization so that can insert guide pin at place, 2 dimension location.
This utility model provides a kind of thinking and method of femoral power condyle positioner; the method and the approach of this technical scheme of specific implementation are a lot; the above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from this utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.The all available prior art of each ingredient not clear and definite in the present embodiment is realized.
Claims (5)
1. a femoral power condyle positioner is characterized in that, comprises first scale and second scale, and flexibly connects between first scale and second scale;
