Abstract
The utility model relates to an improved artificial femoral head which can realize bone grafting fusion, and belongs to the technical field of the medical appliance. The utility model provides an improved artificial femoral head which can realize bone grafting fusion which is easy to be grafted, has good stability, and can prevent loosening, rotating, and sinking. The improved artificial femoral head adopts the technical proposal that improved artificial femoral head which can realize bone grafting fusion is composed of a femoral head handle, a femoral head neck, and a double acting header provided with an inner pole layer and an outer pole layer, wherein the lower part of the femoral head handle is a hollow tubular, the lower end is open, and a plurality of inner and outer communicated through holes are uniformly distributed on the pipe wall. When the improved artificial femoral head is used, the lower hollow part of the femoral head handle can be grafted into the broken bones of the patient before the femoral head handle grafted into the bone, then the femoral head handle is grafted into a femoral head cavity, through the method, the grafted bone can pass through the through holes and can grow to be combined with the bone cortex around the inside the femoral head cavity, and the loosening and sinking problems of the femoral head handle can be solved after the artificial femoral head is grafted.
Description
Technical field
This utility model relates to a kind of artificial thigh bone for the treatment of fracture of femoral neck and femur head necrosis, belongs to technical field of medical instruments.
Background technology
Fracture of femoral neck and femur head necrosis are a kind of common diseases, especially more in elderly population see more.The best approach of treatment is changed the implantable artificial femoral head with the femoral head that damages.At present, have 30 both at home and abroad surplus kind of artificial thigh bone, its shank shape big country small difference, just material and surface texture are different.On the material, have vitallium, titanium alloy, pottery, jade etc. multiple, on the surface configuration, have on the handle with holesly, pelmatozoa is made many micropores, Corallium Japonicum Kishinouye face etc. impelling bone to grow into, its purpose all be prevent loosening with sink.But through clinical practice with follow up a case by regular visits to for a long time, finds that still there is phenomenon loosening and that sink in above-mentioned these artificial femur shanks in femoral bone cavitas medullaris, after particularly long-time the use, loosening and sinking is in various degree arranged nearly all.In order to improve loosening behind the artificial femoral head replacement surgery and to sink, generally adopt modes such as bone cement or bone block self locking.Adopt the bone cement person, worrying owing to the toxic side effects of bone cement itself; And adopt the reliability of bone piece self-marketing to fall under suspicion always.In addition, the artificial thigh bone handle of prior art mostly is bend handle type greatly, is fit in order to make its handle and proximal femur pulp cavity, often needs to enlarge with the pulp cavity file.File too muchly, it is easily loosening that artificial thigh bone is inserted the back; File too smallly, easily cause again in the artificial thigh bone insertion process the splitting of proximal femur sclerotin.Up to the present also there is not a kind of ideal artificial thigh bone that can thoroughly solve loosening and sinking problem.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of implantation easily, good stability, but can prevent the improved bone-graft fusion artificial thigh bone that becomes flexible, rotate, sink.
The technical scheme that solves the problems of the technologies described above is:
But a kind of improved bone-graft fusion artificial thigh bone is made up of the double motion head of utmost point layer in femoral stem, neck of femur and the band and outer utmost point layer, and its improvements are that the bottom of femoral stem is a hollow tubular, lower ending opening, a plurality of through holes that are interlinked to the outside in being evenly equipped with on the tube wall.
But above-mentioned improved bone-graft fusion artificial thigh bone, the length of described femoral stem hollow space is 2-5cm.
This improved artificial thigh bone, before femoral stem is implanted, femoral stem hypomere hollow space is implanted the capital broken bone that the patient takes off, again with femoral head handle implanted unit bone cavity, the bone of Zhi Ruing will grow together with cortical bone on every side like this, has thoroughly solved artificial thigh bone and has implanted the problem that the back femoral stem is loosening and sink.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the A-A cutaway view of Fig. 1.
Labelling is as follows among the figure: femoral stem 1, neck of femur 2, double motion head 3, hollow tube wall 4, through hole 5, projection 6
The specific embodiment
Show among the figure, but this improved bone-graft fusion artificial thigh bone is made up of the double motion head 3 of utmost point layer and outer utmost point layer in femoral stem 1, neck of femur 2 and the band.A plurality of kicks 6 are arranged on the outer surface on the top of its femoral stem 1, and the bottom is different from common solid construction, and makes hollow tubular, its lower ending opening, a plurality of through holes 5 that are interlinked to the outside in being evenly equipped with on the hollow tube wall 4.The effect of uniform through hole is on this hollow structure and the tube wall: before artificial femur handle 1 implanted unit bone cavity, artificial femur handle 1 hypomere hollow space is implanted patient's broken bone, again with in the artificial femur handle 1 implanted unit bone cavity, the broken bone that is implanted into of the cavity of artificial femur handle 1 will pass through hole uniform on the hollow tube wall 45 and grows together with cortical bone in the femoral cavity on every side like this, has thoroughly solved artificial thigh bone and has implanted the problem that the back femoral stem is loosening and sink.The length of above-mentioned hollow space is that about 1/3 of artificial femur handle 1 is advisable, and the length of present embodiment is 2-5cm.
This improved artificial thigh bone not only can solve artificial thigh bone and implant the problem that the back femoral stem is loosening and sink, and can also prevent that the artificial thigh bone handle passes cortical bone or the phenomenon of proximal femur splitting is taken place during insertion.
Operation method:
Get the Muller route, the otch mid point is positioned at the greater trochanter top, extends along femoral shaft.Appear hip joint, excision the place ahead joint capsule, osteotomy under the neck of femur head is taken out femoral head.Along the joint capsule of acetabular bone labrum glenoidale excision remnants, and with antiseptic gauze filling acetabular bone.Peel off the soft tissue of neck of femur to intertrochanteric line the place ahead, take the photograph the neck of femur osteotomy plane that the sheet template is determined by X line before the art, make the neck of femur osteotomy once more, osteotomy line inboard generally exceeds the about 1cm of lesser trochanter upper limb, all amputation of the neck of femur outside.Ascending pulp cavity expander and pulp cavity file with different model enlarges pulp cavity till satisfied.The femoral head handle handle that model is suitable inserts pulp cavity, and hammering adapter tail end makes bigelow's septum hold the bottom surface of prosthese handle just gently.Settle the prosthese medicated cap.Stretch, traction, inward turning lower limb, include artificial thigh bone in acetabular bone.After the X line is taken the photograph sheet and confirmed that the position is good, place negative-pressure drainage tube in the depths, joint.The layer-by-layer suture otch.
