Abstract
Disclosed is an acetabulum matched shape adaptable blade plate which belongs to the medical device technical field and is used for solving the disadvantages found in the coaptation of the acetabulum fracture in complicated structure, infirm connection and inconvenient application when a plurality of blade plates are used. The technical proposal of the utility model is that the utility model is a thin metal plate whose one side is a long strip blade plate; one side of the long strip blade plate is extended outwards to form an arc plate surface; the shape of the arc plate surface is matched with the shape of the ischial tuberosity; a fixing screw hole is vertically arranged on the long strip blade plate; a fixing screw is arranged on the arc plate surface; the horizontal surface of the plate metal plate is flexural; and the flexural radian of the metal plate is matched with the arc shape of the acetabulum. The utility model has great holding force on the fracture block because of the screw fixation and has firm ret, and is not easy to fall off; the incisions for implantation and removal are reduced because of the small area of the blade plate so that the implantation and removal become easy and the suffering of patients is lightened; meanwhile, a metal plate in the utility model can be used as a plurality of reconstruction plates, so the cost is low and the economic burden of patients is greatly reduced.
Description
Technical field
This utility model relates to a kind of anatomical form blade plate for the treatment of acetabular bone rear portion fracture, belongs to technical field of medical instruments.
Background technology
Fracture of acetabulum is the common orthopaedic disease of middle-aged and elderly people, and the important step of treatment acetabular bone rear portion fracture is with fixing after the reduction of the fracture.Usually the fixing means that adopts is to be placed on the reservation position with one or more reconstruction plate after the reduction of the fracture of acetabular bone rear portion at present, and the screw hole that the reuse hold-down screw passes on the blade plate is fixed fracture anatomical reduction.The shortcoming of this method is: at first, when using a blade plate, owing to acetabular bone position anatomic form complexity, classification of fracture complexity, only not ideal enough by the fixed effect of reconstruction plate screw of a block length bar shaped.Secondly, when using the polylith blade plate fixedly, each blade plate is independently, does not have traction action between mutually, so firm inadequately to the fracture fixation of complexity; And use the polylith blade plate, also have the fixed in position complexity, the shortcoming bigger soft tissue destruction.In addition, use the polylith blade plate to fix, the expense costliness increases the financial burden of patient and society.
Summary of the invention
Technical problem to be solved in the utility model is to overcome in the prior art shortcoming of using the polylith blade plate to cause, provide a kind of simple in structure, be connected firmly, the suitable shape blade plate of fracture of acetabulum easy to use.
The technical scheme that solves the problems of the technologies described above is:
A kind of fracture of acetabulum is fitted the shape blade plate, it is the metal sheet body, one side of plate is the strip blade plate, one side of the rectangular blade plate camber plate face that stretches out, this arc face shape and ischial tuberosity shape are complementary, and vertically are provided with fixing threaded hole at rectangular blade plate, and the arc face is provided with fixing threaded hole, the horizontal plate face of plate body is a bending, and crooked radian and acetabular bone outside arcuate shape are complementary.
Above-mentioned fracture of acetabulum is fitted the shape blade plate, and an end of described arc face is set up a strip fixing head, and the angle α of the direction of this rectangular fixing head and rectangular blade plate direction is 12 °-60 °, is provided with fixing threaded hole on rectangular fixing head.
Above-mentioned fracture of acetabulum is fitted the shape blade plate, and the central authorities of described arc face are provided with the hole.
Above-mentioned fracture of acetabulum is fitted the shape blade plate, and the quantity of described fixing threaded hole is 5-20, and wherein fixing threaded hole is along the vertical uniform distribution of rectangular blade plate, and fixing threaded hole is along the vertical uniform distribution of rectangular fixing head, and fixing threaded hole is along arc face edge uniform distribution.
Above-mentioned fracture of acetabulum is fitted the shape blade plate, and described metallic plate material is steel or titanium alloy.
This utility model with intersect the fracture bone plate of placing more than two and compare, can have the fixed range identical with it, has not available globality of polylith blade plate coupling and stability simultaneously, this blade plate form and acetabular bone rear portion are dissected close, can make blade plate and fracture of acetabulum position anatomic form matched well, therefore and can be after the reduction of the fracture is fixing, form that can utilization itself guarantees fixing near normal configuration of fracture.When operation technique, use this blade plate will reduce operative incision, minimizing is peeled off soft tissue, less compressing to periosteum, the healing that is more conducive to fracture is placed and taking-up also will be more prone to.This blade plate cost is low, will alleviate the medical burden of patient and society greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the K of this utility model in Fig. 1 is to side view.
Labelling is as follows among the figure: rectangular blade plate 1, circular arc plate face 2, fixing threaded hole 3-1, fixing threaded hole 3-2, fixing threaded hole 3-3, rectangular fixing head 4, hole 5, acetabular bone 6, femoral head 7.
The specific embodiment
Fig. 1 shows that present embodiment is a kind of acetabular bone rear wall or rear pillar fracture fixation bone fracture plate, and visible blade plate is in the position of acetabular bone 6 and femoral head 7 among the figure.It is made by the sheet metal of steel or titanium alloy material.The plate face is that a rectangular blade plate 1 connects a circular arc plate face 2, end at circular arc plate face 2 also is connected with a rectangular fixing head 4, rectangular blade plate 1 is 20 ° with the angle α of rectangular fixing head 4, global shape similar " R " letter, but one the lifting one's head on vertical of left.Circular arc plate face 2 edges and ischial tuberosity edge shape are complementary, and dissect behind the form of whole blade plate and the acetabular bone to adapt.The quantity of fixing threaded hole is 5-20 altogether, and the doctor can fix with hold-down screw by these fixing threaded holes as required.In the illustrated embodiment, fixing threaded hole 3-1 is along rectangular blade plate 1 vertical uniform distribution, and fixing threaded hole 3-2 is along rectangular fixing head 4 vertical uniform distribution, fixing threaded hole 3-3 arc face 2 edge uniform distribution.
In order to alleviate the weight of whole blade plate, can also portal 5 in the central punching press of circular arc plate face 2, the size in hole 5 is exceeded with the plate face intensity that does not reduce blade plate.Fig. 2 shows that from the side of the suitable shape blade plate of fracture of acetabulum, the horizontal plane of plate face is a bending, and crooked radian and acetabular bone bone 6 outside arcuate shape are complementary.
The fracture of acetabulum fixation bone fracture plate of this structure adopts screw to fix, and is bigger to the hold of sclerite, and resets firmly difficult drop-off; The blade plate area is little, and the otch of placing and taking out all greatly reduces, and places and take out all to be easy to, and has alleviated patient's misery.And one block plate be equivalent to the polylith reconstruction plate, cost is low, has alleviated patient's financial burden greatly.
