Description
Technical field
The present invention relates to the mould used in orthopaedics hip replacement surgery, particularly to a kind of personalized hip joint spacer mold manufacture method.
Background technology
Along with three-dimensional printing technology is going deep into that medical industry is applied, the personalized hip implant metal prostheses of 3 D-printing also gets more and more, and postoperative infection after endoprostheses replacement is a very scabrous complication, treats extremely difficult. Application is most common at present is by secondary revision procedure: artificial joint prosthesis is taken out by first time operation, and carries out debridement thoroughly; After patient infects and controlled, then carry out second time operation and implant new prosthese. The empty position after by taking-up prosthese is needed to occupy with other object in operation interim, to prevent periarticular soft tissues contracture from causing difficulty to second time operation. The use of type antibiotic bone cement occupier can prevent soft tissue contracture, can control to infect simultaneously, at present, uses joint type antibiotic occupying device to carry out second phase revision procedure and has become as the method generally acknowledged in the world. Hip joint spacer many employings bone cement makes, and for preventing from infecting and reducing operating time, the making of occupying device needs field fabrication in situations in the surgery room, to keep gnotobasis. This just requires that the making of occupying device is convenient and swift, reliable, it is secure to make precision. The making of conventional antibiotic bone cement spacer has pinches mold forming method by hand and utilizes the shaping dies of seriation to make.
Pinch the occupying device of mold forming by hand, utilize bone cement and antibiotic compatibility by a certain percentage, kneading becomes the occupying device with the similar shape of patient's sclerotin, because its precision is low, articular surface shape can not well with patient's sclerotin matching, easily causing and occur abrasion to cause further bone loss between occupying device and acetabular bone sclerotin, patient is subject to bigger restriction in operation activity interval, and Production Time is long.
Utilize mould directly to make occupying device in operation and to some extent solve articular surface problem of rough, also more can meet patient's sclerotin form in shape.Mould is broadly divided into two kinds according to material difference, and a kind of is metal mold, can repeatedly sterilizing reuse, and conventional mould is femoral component and the structure of femoral shaft parts one, and model alternative is few; And it is more complicated with the hip joint spacer mold structure that various sizes of femoral bone cavitas medullaris parts freely mate to realize various sizes of femoral component, and metal die needs machining, relatively costly; Another kind is mould of plastics, also it is pre-manufactured commercial mould of plastics, through special modality, Bone cement gun is utilized to be injected in mould of plastics by antibiotic for band bone cement, after bone cement hardens, mould of plastics is cut off along specific direction, just can being taken out by the occupying device of molding and use, this kind of plastics occupying device mould is expendable consumed product, disposable, not reproducible utilization, thus quantity in stock is big. Commercial occupying device decreases the time directly making occupying device in art, accelerates procedure, but this occupying device is costly, increases patient burden, and quantity in stock is big, needs aseptic packaging, there is effect duration problem. And this mould is seriation, it is impossible to realize personalized spacer mold and make.
Summary of the invention
In view of this, it is an object of the invention to provide a kind of personalized hip joint spacer mold manufacture method, the mould produced can realize personalization, low cost, quick Fabrication occupying device.
It is an object of the invention to be achieved through the following technical solutions:
A kind of personalized hip joint spacer mold manufacture method, comprises the steps:
1) scanning patient's hip joint data, and import to Mimics modeling software, by Morphological scale-space, generate visualization hip joint threedimensional model, in Geomagic software, hip joint threedimensional model is carried out grid optimization, obtain hip joint physical model;
2) hip joint physical model is imported Top-Down Design software UG, design occupying device model design based on this above mould or counterdie in conjunction with occupying device model library;
3) utilize three-dimensional printer to print described occupying device model and upper mould or counterdie, polish after having printed;
4) by silica gel feed liquid and firming agent 100:(1-2 by volume) ratio mix, and stir 3-5 minute so that it is be sufficiently mixed;
5) the occupying device model printed is put into the upper mould or drag intracavity that print, and do framed being surrounded, the occupying device femur marrow part printed near femoral head branch center a bonding pole to form sprue gate, a small column is placed to form exhaust port passageways at occupying device femur marrow afterbody, in this, as reverse mould mother matrix, by step 4) silica gel that mixes be fed into framed in;
6) by the silica gel evacuation that irrigated 18-22 minute so that it is bubble overflows, and stands 12-14 hour afterwards, makes silica gel solidify;
7) silica gel after solidifying is then the counterdie of occupying device or upper mould; the occupying device model printed is put into this counterdie or upper model cavity; one layer of vaseline of topcoating on silica gel mould; as mother matrix by step 4) silica gel that mixes be fed into framed in; according to step 6) make mould or counterdie on silica gel, two silica gel moulds cooperate and are hip joint spacer mold.
The invention has the beneficial effects as follows:
Hip joint spacer mold manufacture method of the present invention, the mould of making is made up of silica gel material, and deformability is good, it is easy to the demoulding, and Production Time is short, with low cost;This mould is obtained silica gel reverse mould mother matrix by 3-D scanning, Top-Down Design and three-dimensional printing technology, and personalizable designs, and precision is high, and the occupying device made is high with patient's matching.
