Abstract
The invention provides a thighbone size measuring device. The device comprises a device body, a measuring ruler and a handle; four nail holes are formed in the device body, and every two nail holes form a group for determining an outer rotating angle. According to the thighbone size measuring device, the detachable design is adopted, and thus the device body, a proportional needle and the handle can be mounted or dismounted as requirement; meanwhile, the measuring ruler is inserted into a round groove in the top end of the device body and can freely rotate, so that a doctor can use conveniently; scale lines are formed in the device body and the measuring ruler; the femoral condyle size of a patient can be determined by adjusting the position of the measuring ruler in the operation; compared with the existing thighbone size measuring device, the thighbone size measuring device has the advantages that the two scale lines are utilized for double determining, and therefore, the accuracy of femoral condyle size measurement can be ensured.
Description
Technical field
The present invention relates to a kind of femur size measuring device, it is mainly used in the total knee replacement in surgical implant artificial knee joint joint replacement.Condyle of femur size survey tool specifically in knee prosthesis.
Background technology
There is considerable time in condyle of femur size survey tool, is the supplemental measurement tool in artificial knee replacement surgery.In artificial knee replacement surgery, doctor is by size measuring device, with reference to form after adopting, two holders of bottom part body fit tightly with femoral-posterior condyles, regulate dip stick, measure the condyle of femur size of patient, and then the model size of the osteotomy plate adopted when determining next step osteotomy and final prosthese model size.While determining condyle of femur size, because human femur under loading condyle carries 3 ° of outer swing angles, realize 3 ° of outward turnings by the location nail on femur size measuring device, during guarantee osteotomy, in femur, lateral condyle osteotomy amount is identical.
Common femur size survey tool is made up of size measuring device main body, dip stick and size measuring device handle.By the size of the model of prosthese according to prosthese anteroposterior diameter size being marked in size measuring device main body, according to the position readings of dip stick, determine the size of osteotomy plate and prosthesis size.With the femur size survey tool of this design, often due to doctor's being unfamiliar with operation technique, Q point can accurately be stuck in than pin front end apical location, model is caused to be determined not accurate enough, finally cause prosthese model to select not mate with patient femur's condyle, reduce surgical quality, bring misery to patient, reduce minimal invasive treatment's quality, this is flagrant.In addition, because common femur size measuring device is metal material, structural design is comparatively heavy, light not.And when doctor does not carry out that tibial side osteotomy is disposable completes the operation of femur side, the existence due to hyperosteogeny and soft tissue is difficult to size measuring device to insert.
Although some femur size measuring devices increase the measures such as adjusting device solve the inadequate problem of certainty of measurement, owing to being subject to the factors restrictions such as using method, effect is very bad.
In sum, at present for easy to use, structure is simple, and certainty of measurement is high thus femur size survey tool that is guarantee operation safety still exists very large demand.
Summary of the invention
The object of this invention is to provide a kind of certainty of measurement high, design small and exquisite, save the femur size measuring device of operating time, thus facilitate doctor to use as far as possible.
For achieving the above object, the invention provides a kind of femur size measuring device, comprise measuring device main body, slide bar, dip stick and measuring device handle, it is characterized in that, described measuring device main body is provided with scale and is parallel to the main chute of scale size variation direction setting, accommodate the slide bar of indicating graduation in described main chute, the end winding support that described slide bar stretches out described main chute is provided with dip stick chute, and sliding in described dip stick chute is provided with dip stick.
Preferably, the bottom of described measuring device main body is provided with handle away from the position of described dip stick.
Preferably, described measuring device lower body part is provided with the handle running through described measuring device main body and installs through hole, and the dismountable plug-in mounting in one end of described handle is fixed on described handle to be installed in through hole.
Preferably, the damping structure stoping and offset before and after described dip stick is provided with in described dip stick chute.
Preferably, described dip stick is provided with the dip stick scale of the setting direction being parallel to described dip stick chute.
Preferably, the lateral symmetry in the middle part of described measuring device main body is provided with a pair wing plate, wing plate described in every side all has symmetrically arranged outward turning nail.
Preferably, wing plate described in every side is all in position arranged two outward turning nail, central horizontal direction distance 3mm, vertical direction distance 2.2mm both it.
Femur size measuring device of the present invention adopts with dismountable dip stick and handle, overall appearance design is smaller and more exquisite, for femur size measuring device adds handle, form a lever arm of force in use, conveniently when doctor does not carry out Tibial osteotomy, femur size measuring device is inserted in joint space.Dip stick can insert in main body and rotate freely movable, is provided with damping at dip stick and dip stick slide bar contact portion, and before and after occurring when preventing dip stick from measuring, skew causes measuring inaccurate.Relatively existing femur size measuring device, dip stick of the present invention carries out the mark of size model, read scale determination model by first time in main body in operation after, second time can have been carried out on dip stick and determine, ensure certainty of measurement, be convenient to the operation in surgical.
