Description
Technical field
This utility model relates to a kind of medical instruments field, be particularly related to a kind of customization and can absorb bone-knitting device, wherein said customization can absorb bone-knitting device and comprise a blade plate and a retaining element, the wherein said knochenbruch place that is fixedly able to described blade plate to be fixed on patient, for being fixed patient's knochenbruch.
Technical background
Within the scope of current medical level, in to the internal fixation treatment of fracture patient, being most widely used of dissection type bone fracture plate.The diversity that existing dissection type bone fracture plate exists due to individual patients on skeletal form and the diversity of fracture and degree, even if it is enough thin that blade plate manufacturer divides the model of blade plate, the anastomose property of blade plate and bone surface and the position of screw are not still ideals very.
Therefore, in the process of implementing at traditional methods of internal fixation to patient's fracture, need medical personnel must prepare blade plate model and specification enough, that may use in the preoperative, nonetheless, still there will be blade plate not meet the situation of patient's actual needs, therefore, in the process of operation, often need to carry out blade plate provisional moulding again, otherwise, need to sacrifice the shape that correctness that fracture resets is yielded to blade plate.Such mode has not only increased the randomness occurring in operation process, the operation easier that increases operation, and the correctness that the surperficial anastomose property of blade plate and patient's fracture, interior fixing stability and fracture reset is all difficult to guarantee.
Aspect the material selection of blade plate, for medical stainless steel, titanium or titanium alloy material, this cold deformation is prohibited from using in theory, because cold bending will change the metallographic attribute of material internal, to such an extent as to has reduced intensity and the decay resistance of blade plate.It is many-sided causing the reason of the knochenbruch failure of immobilized patients fracture, such as not meeting on the position moulding, screw hole again of blade plate the effect that the needs etc. of fracture knochenbruch all can be internally fixing in operation, produces inevitable impact.In addition, these reasons also can cause the knochenbruch healing delay of patient's fracture, and malunion or bone does not connect even occur blade plate fracture, take out the problems such as difficulty.
Except the deficiency of above technological layer, in the process of traditional blade plate molding, which type of blade plate final decision is used, even if understand the orthopedist of the blade plate characteristic product that apparatus relevant enterprise provides that is also merely able to be medically treated passively most.In the process of clinical practice, even if find that traditional blade plate exists area for improvement, for blade plate itself, orthopedist does not have to make and to improve and adjust product yet, be merely able to relevant information to feed back to relevant medical apparatus and instruments enterprise, then by them, improved.Also there is very large problem in the screw for fixation bone fracture plate of traditional blade plate.
Specifically, the screw of current clinical use and the contact site of screwdriver are interior hexagonal or M shape, also with interior hexagonal or M shape screwdriver, be screwed into or back-out, when union of fracture firm, there is cold welding in nut and steel plate, when screw physicochemical property changes because of long-term internal milieu, " stripped thread " phenomenon that just there will be screwdriver to skid on nut, directly cause screw to take out, now one fixingly in simple is taken out operation and is transformed at once complicated, need to be by special apparatus, sacrifice local bone amount, extend the more highly difficult hands art of operating time, also bring infection rate to increase, the risk of refracture in art.
Along with the rise of (being called again rapid shaping technique) of 3D printing technique, it is widely used in the every field in society, especially revolutionary especially on the impact of medical apparatus and instruments.Therefore, on market, need the blade plate of a 3D of utilization printing technique, fill up the blank in this field that segments market, thereby alleviate the misery of fracture patient, and obtain best result of use.
