Background technology
Along with continuing to increase and the quickening of global integration process of national supporting dynamics, China Medical Device industry obtains the development of advancing by leaps and bounds.Wherein, the medical apparatus and instruments being just similar to orthopedic navigation system along with some arises at the historic moment, and this system can greatly reduce the risk of complicated bone surgery, and brings a kind of new operator scheme-visual surgical technic for bone surgery technology.This bone surgery utilizes navigation system to formulate in the preoperative in surgical planning and art and navigates, operating theater instruments can be followed the tracks of in operation process, and real-time update on the image of the position of operating theater instruments patient in preoperative or art is shown, operative doctor is allowed to know the relation of the position of operating theater instruments with sufferer anatomical structure at any time, possesses again complete navigation feature simultaneously, can the moving forward and backward of sham operated apparatus, so make the process of performing the operation more accurate.
About orthopedic navigation device, have been reported in prior art, as Chinese invention patent (publication number: CN101332137A) discloses a kind of long bone fracture traction reduction navigation apparatus, it comprises mover mechanical arm, passive mechanical arm, photoelectric tracer, end effector, locomotive, tracking mark assembly, spatial point harvester, tracking mark assembly is arranged on long bone fracture place, spatial point harvester is held in doctor's hands, mover mechanical arm and passive mechanical arm are arranged on locomotive respectively, photoelectric tracer is arranged in mover mechanical arm, end effector is arranged on passive mechanical arm, locomotive is provided with computer.Although this device volume is less, locomotive is removable, moves or puts in position, put and also do not take up space time easy to use.But this device overall structure is comparatively scattered, backward, imperfection, contacts defective tightness with modern bone surgery, makes this device in use be subject to many limitations.In addition, the material that current medical apparatus and instruments adopts is rustless steel or common alloy material is made, although the medical apparatus and instruments that these materials are made can substantially meet the demands in intensity and rigidity, but performance is general, and this density of material is large, and the medical apparatus and instruments entirety made is heavier.
Summary of the invention
The present invention is directed to the defect existing for prior art, a kind of compact overall structure, the orthopedic navigation device that perfect, support bar intensity is high, good rigidly, total quality are light are provided.
Above-mentioned purpose of the present invention realizes by following technical proposal: a kind of orthopedic navigation device, comprise mobile box, described mobile box top is provided with the first movable device, body side is provided with the second movable device, mobile box front end face is provided with controlling organization, first movable device is provided with optronic tracker and the first display, second movable device is provided with second display, described first movable device comprises the first support bar be flexibly connected successively, first lever arm, first swinging mounting and the first mounting base, described optronic tracker is connected with the first mounting base, first display is flexibly connected with the first support bar, described second movable device comprises the second support bar be flexibly connected successively, second swinging mounting, second lever arm and the second mounting base, described second display is connected with the second base runner, described first lever arm and the second lever arm all can automatically reset, wherein, the material of described first support bar and the second support bar is titanium alloy, described titanium alloy is grouped into by the one-tenth of following percentage by weight: Al:2-7%, Sn:0.5-3%, Zr:0.5-3%, Mo:2-4%, V:2-4%, Mn:1-2%, Cr:1-2%, Si:0.1-0.5%, surplus is Ti and inevitable impurity.
In orthopedic navigation device of the present invention, the material of the first support bar and the second support bar is titanium alloy, titanium alloy is formed by the reasonable compatibility of Al, Sn, Zr, Mo, V, Mn, Cr, Si and Ti element, specific strength (strength/density), much larger than other structural metallic materials, can make that unit strength is high, the first support bar of good rigidly, light weight and the second support bar.And with obtained the first support bar of titanium alloy with the second support bar corrosion resistance is good, thermostability high and low temperature performance is good.
Al is the element the most often added in titanium alloy, mainly plays solution strengthening effect, and often add the Al of 1%, titanium alloy room temperature tensile intensity increases 50MPa, but the limit of solubility of Al in titanium is 7.5%, after the dissolubility that oversteps the extreme limit, occurs ordered phase Ti in tissue
3al(α 2), the plasticity of alloy, toughness and stress corrosion are unfavorable, and therefore, the addition of Al is generally no more than 7%.In addition, Al can improve the non-oxidizability of titanium alloy, reduces the density of titanium alloy, improves recrystallization temperature, and the Al as added 5% can make recrystallization temperature bring up to 800 DEG C from 600 DEG C of pure titanium.Al can also improve adhesion between magnesium-titanium solid solution Atom, thus improves heat resistance.In heat treatable beta-titanium alloy, add the Al of about 3%, the fragility caused by metastable state β phase decomposition generation ω phase can be prevented.Al can also improve the dissolubility of hydrogen in alpha titanium alloy, reduces the sensitivity being caused hydrogen embrittlement by hydride.Therefore, in conjunction with these effects that Al is concrete in titanium alloy, the addition of Al controls in the scope of 2-7% by the present invention.
For ensureing that heat-resisting alloy obtains single-phase α and organizes, except Al, the present invention also adds the thermostability that Zr and Sn improves titanium alloy further, and, the impact of Zr and Sn on titanium alloy plasticity is less than Al, and meanwhile, Sn also can reduce the sensitivity being caused hydrogen embrittlement by hydride.But Sn addition exceed a certain amount of after, ordered phase Ti can be formed
3sn, causes the plasticity of titanium alloy and heat stability to reduce.Therefore, in conjunction with the coordinative role of element each in titanium alloy, the addition of Sn and Zr is controlled within the scope of the present invention.
Mo and V energy solution strengthening β phase, and significantly reduce transformation temperature, increase quenching degree, thus strengthen heat treatment reinforcement effect.Can not there is eutectoid reaction in the titanium alloy containing Mo or V, at high temperature structure stability is good.But add V separately, alloy thermostability is not high, and its creep resistance can only be maintained to 400 DEG C, so the effect of adding Mo, Mo raising creep resistance while adding V is better than V, but density is larger.Mo can also put forward heavy alloyed corrosion resistance.Therefore, the reasonable composite use of Mo and V in titanium alloy of the present invention, addition must control within the scope of the present invention.
Mn and Cr is the main adding elements of high-strength metastableβtitaniumalloy, and their strengthening effects are remarkable, stablize β phase ability strong.But they and titanium form slow eutectoid reaction, under the condition of long term high temperature work, tissue is unstable, and creep resistance is low, and, deposit in case at Mo, have the effect suppressing eutectoid reaction.Therefore, the addition of Mn and Cr must be controlled.
The atomic size difference of Si and Ti is comparatively large, and easy fault segregation in place in solid solution, stops dislocation motion, therefore, in titanium alloy, the heat resistance that Si can improve alloy is added, equally, the addition of Si element can not be excessive, and in the present invention, the addition of Si element is advisable with 0.1-0.5%.
