Abstract
The utility model relates to a multifunctional four-in-one osteotomy device, which is mainly used for femoral lateral osteotomy in orthopaedic artificial knee joint replacement surgery. The osteotomy device consists of an osteotomy device main body, an adjustable fixed nail plate and an adjusting eccentric wheel. Compared with the conventional four-in-one osteotomy device, the multifunctional four-in-one osteotomy device has the advantages that the osteotomy quantity can be upwards or downwards adjusted for 1 millimeter and 2 millimeters according to the individual bone situations of patients based on standard osteotomy respectively. By adopting the osteotomy device, the biological compatibility between an artificial cut bone and a human physiological bone is furthest ensured, and perfect matching of an artificial femoral condyle prosthesis installed later and the human physiological bone is realized.
Description
Technical field
This utility model relates to a kind of multi-functional four unification osteotomy devices, and it is mainly used in the osteotomy operation of femur side in the orthopaedics replacement knee in arthroplasty.Replacement knee in arthroplasty femur side osteotomy instrument specifically.
Background technology
Replacement knee in arthroplasty femur side osteotomy instrument considerable time occurred.In the artificial knee replacement surgery, due to femur side osteotomy instrument and human bone coupling, usually the position of femur side osteotomy is inaccurate or obviously know incorrect but can't adjust.This directly can cause condyle of femur to be in place, and the calamitous risk that is difficult to expect occurs.At this moment just need to there be a kind of safe, that be simple and easy to use, knee joint femur side osteotomy instrument that regulatory function is arranged to address this problem.
Have five osteotomy grooves in the middle of common replacement knee in arthroplasty femur side osteotomy instrument Chang Weiyi monoblock osteotomy plate, plate, five osteotomy grooves are groove, and the goose saw sheet can be truncated into condyle of femur by the osteotomy groove shape of regulation.Two wire nails are arranged bottom common femur side osteotomy plate, be used for fixing whole osteotomy plate.After this common femur side osteotomy plate is located by wire nail, can not adjust.Can only reorientate installation by locating apparatus if adjust.This can delay the operation process, reduces the operation quality, brings more misery to the patient, and this is flagrant.
Although some companies adopt the measures such as a plurality of spacing staples, interpolation adjustment hone lamella to solve this problem, because factors such as being subject to using method limits, effect is very bad.
In sum, for easy to use, simple in structure at present, still there is very large demand in the replacement knee in arthroplasty femur side osteotomy instrument that can conveniently regulate.
The utility model content
This utility model purpose is in order to satisfy orthopedist's demand, makes up present replacement knee in arthroplasty femur side osteotomy apparatus and falls behind situation, and a kind of replacement knee in arthroplasty femur side osteotomy apparatus that can conveniently regulate is provided.
In order to realize this utility model purpose, this utility model adopts following design:
A kind of multi-functional four unification osteotomy devices, it is comprised of osteotomy device main body, adjustable fixedly nail-plate, eccentric adjustment wheel three parts.The osteotomy device bottom part body has a dovetail groove, and adjustable fixedly nail-plate is trapezoidally to slide in the dovetail groove of osteotomy device bottom part body.Two square column spikes are arranged at adjustable fixedly nail-plate bottom.One Long Circle through hole is arranged on adjustable fixedly nail-plate, and the eccentric of eccentric adjustment wheel passes this through hole.Regulate the position of adjustable fixedly nail-plate by eccentric rotation.The eccentric offset of eccentric adjustment wheel is 2mm.Osteotomy device main body, adjustable fixedly nail-plate, eccentric adjustment wheel three parts are the medical stainless steel material manufacture.A kind of multi-functional four unification osteotomy devices of this utility model can be regulated the osteotomy amount of osteotomy device after osteotomy device is installed, convenient and swift, have farthest guaranteed operation quality and safety, save operating time.
Advantage of the present utility model and benefit:
1, the multi-functional four unification osteotomy devices of this utility model, simple in structure, easily makes.
2, the multi-functional four unification osteotomy devices of this utility model can be adjusted the osteotomy amount after osteotomy device is fixing, and are convenient and swift.
3, the multi-functional four unification osteotomy devices of this utility model adopt square column spike to fix, and are solid and reliable.
4, the osteotomy device main body of the multi-functional four unification osteotomy devices of this utility model, adjustable fixedly nail-plate, eccentric adjustment wheel three parts are medical stainless steel material manufacture, material safety.
Foregoing has illustrated the beneficial effect of this utility model patented technology scheme fully, below in conjunction with the drawings and specific embodiments, this utility model is done further narration, so that the public has a better understanding the utility model content, the embodiment of the specific embodiment is best technical scheme, and is not limitation of the utility model.

The specific embodiment
As shown in Figure 1 and Figure 2, a kind of multi-functional four unification osteotomy devices, it is comprised of osteotomy device main body 1, adjustable fixedly nail-plate 2, eccentric adjustment wheel 3 three parts.One dovetail groove is arranged at osteotomy device main body 1 bottom, and adjustable fixedly nail-plate 2 slides in the dovetail groove of osteotomy device main body 1 bottom for trapezoidal.Two square column spikes 4 are arranged at adjustable fixedly nail-plate 2 bottoms.One Long Circle through hole is arranged on adjustable fixedly nail-plate 2, and the eccentric 6 of eccentric adjustment wheel 3 passes this through hole.Regulate the position of adjustable fixedly nail-plate 2 by the rotation of eccentric 6.Eccentric 6 offsets of eccentric adjustment wheel 3 are 2mm.Osteotomy device main body 1, adjustable fixedly nail-plate 2, eccentric adjustment wheel 3 three parts are the medical stainless steel material manufacture.During use, two square column spikes 4 of adjustable fixedly nail-plate 2 insert condyle of femur 8 by locating in prefabricated circular hole, swing saw blade 7 by osteotomy groove 5 osteotomy of osteotomy device main body 1.When needs change osteotomy site, turn eccentric adjustment wheel 3, osteotomy site can be to both sides mobile 1-2mm respectively.Appropriate mobile osteotomy site can guarantee the agreeing with property of biology between artificial osteotomy and Human Physiology bone, realizes the Perfect Matchings of later stage installation condyle of femur artificial prosthesis and Human Physiology bone.
