Abstract

The invention belongs to the medical field of operation devices, in particular to a 3D biological force conduction artificial prosthesis. The problem to be solved is that exists in the background art: all the implantation prostheses are a supporting platform of a 2D planar bone and a joint bone surface, which leads to stress shielding, osteotrophy shielding, stress concentration to cause micro-fracture, tensile stress obstacle and the like, and result in loosening due to bone absorption, and then the operation must be failed finally, brings a new illness and disablement to a patient. The technical scheme is that: through a 3D biological force conduction bone internal depth even transmission manner, spiral force transmission plates with mutually parallel planes are arranged around an inner support column to form an implantation prosthesis; and the surfaces of the spiral force transmission plates are made into mesh structures to be integrated with the bone. The artificial prosthesis can be used independently or in combination, can be applied to joint prosthesis, artificial limb and dental implants and the like, can effectively prevent prosthesis loosening due to bone absorption, and can remarkably prolong the service life of the implantation prosthesis, or stop the implantation prosthesis loosening.

Description

The biological power conduction artificial prosthesis of three D

The biological power conduction artificial prosthesis of technical field: the invention belongs to the surgical prosthesis of medical field, particularly three D.

Background technology: since nearly half a century, needs and the application of Artificial Intervention prosthese are used widely, and especially the investigation and application of bone inner support implanting prosthetic brings great convenience to the mankind, such as artificial tooth, artifucial limb and artificial joint prosthesis etc. But all bone being implanted into property prostheses are because after two D surface Integrated implant, the biological power conduction surface of limbs compares limitation, its degree cannot obtain long-term stability, finally causes that the bone of Periprosthetic dissolves, bone resorption, osteoporosis and osteanabrosis, makes prosthetic loosening and failure. And the development along with science and technology, the excellent biomaterial of biocompatibility comes out successively and after entering into clinical application, it is also how relevant with mechanics factor that people recognize that again bone is implanted into the failure of prosthese gradually. Therefore, the performance that people start to emphasize to evaluate the implanting prosthetics such as artificial prosthesis in recent years needs to comprise biocompatibility and biomechanical compatibility two aspects. But biomechanical compatibility mainly comprises six aspects: (1) implanting prosthetic is wanted to bear function load, has enough intensity, ensure gross distortion or rupture failure; (2) bone tissue is produced enough Stress transmit during implanting prosthetic driving functions, avoid bone disuse atrophy; (3) Stress transmit that bone tissue is produced by implanting prosthetic can not exceed physiology limit, to prevent the bone resorption that causes of bone wound and osteanabrosis. (4) effective maintenance that the implanting prosthetic after the natural osteoporosis how tackling adjoint human senility appearance, osteanabrosis and the bone resorption easily ignored is permanent. (5) what especially more easily ignore is the power conduction that only considered between two dimensional planes of two D surface Integrated implant, but ignores the biological three-dimensional stress conduction physiological property of Integrated implant in bone completely. (6) and for nutrition blocking property sclerotin nutrition disorder osteanabrosis problem lasting around implanting prosthetic. It is well known that the bone adaptation reaction Wolff law around implanting prosthetic, bone has the ability of biological adaptability reconstruction, once beyond this kind of ability, successive destruction has just been suffered in adaptability reconstruction.Stress because of implanting prosthetic-bone interface exists again, and the stress on interface has three kinds of forms: stress, tension stress and shearing stress. It is rear that both have four interfaces to connect the trend destroyed. Tension stress can make interfacial separation, but the dislocation of shearing stress interface, and these two kinds of stress all need interface to there is certain bonding force to contend with. And implanting prosthetic often loses the structure of tension stress and the maintenance basis of biological function mechanism. If interface does not have bonding force or bonding force too low, the so tension stress on interface and shear stress level, also it is not elevated to the degree that bone resorption can be made to destroy, interface connection herein is just destroyed, define stress to interrupt, load can only transfer to other regions, interface, and there is occurred, and stress is concentrated. The interface region stress level existed in pressure zone is too high, the sporadic stress wound of especially super big load, substantially exceed the tolerance physiology limit of bone, micro-fracture will be occurred to make bone resorption, then implanting prosthetic is caused to loosen, aggravation stress is concentrated and bone wound further, more owing to osteocyte is in constantly and slowly metabolic processes, super huge pressing stress must force area of new bone cell can only give up the throne retraction growth substitute, bone face and gap, implanting prosthetic face must increase gradually and loosen, and finally cause the failure of implanting prosthetic. Again because all implanting prosthetics all lose lasting maintenance structure basis and the function of tension stress, i.e. tension stress obstacle, once a certain amount of bone absorption occurs the sclerotin at Integrated implant interface, stress side, certainly will there is certain interval and start to loosen in tension side; And the implanting prosthetic nutrition that causes Integrated implant face blocks and make the malnutrition of sclerotin, cause osteoporosis and absorption further. Therefore prosthetic loosening is all because the bone two D plane mechanotransduction stability that are implanted into prosthetic surface Integrated implant are not enough, and therefore bone around implanting prosthetic dissolves, bone resorption and osteanabrosis etc. cause prosthetic loosening and failure. It is thus desirable to start the implanting prosthetic producing depth biomechanics conduction high stability in three D bones, implanting prosthetic just can be made to maintain the stability of longer time, or even lifelong stability.

Summary of the invention: it is an object of the invention to provide the Artificial Intervention prosthesis system of the biological power conduction of depth in a kind of three D Integrated implant and the three-dimensional bone of three D, and it combinationally uses, solve in background technology field the deficiency existed, the biotic stress conduction stability of tradition two D Integrated implant is not enough, tension stress obstacle, cause the dissolving of micro-fracture, bone, bone resorption, osteanabrosis etc., finally cause implanting prosthetic loosen and failure. because traditional two D Integrated implant mainly occur in the Integrated implant of bone surface, because bone surface especially articular surface covered by prosthese, cause synovial fluid cutout and lose nutrition, or implanting prosthetic surface nutrient blocks the malnutrition causing osteotrophy obstacle all can cause osteogenesis, thus cause weakening of osteanabrosis stress support ability, it is easy to cause micro-fracture prosthese fine motion. its constitutional features is: the good implanting prosthetic surrounding of surface treated histocompatibility is the stress conductive plate structure of multilayer runs parallel, spiral trend is arranged in stress conductive plate face, around the parallel rule distribution of the central shaft supporting inner prop, stress conductive plate spacing is bigger, stress conductive plate face is broader, flexible thin plate design preferably, stress conductive plate face forms mesh spline structure, stress equilibrium layer distributed is conducted, and sclerotin easily grows in mesh, and the Kazakhstan Fu Shi guard system of bone trabecula can in mesh healthy growth, recover the normal health sclerotin nutritional status before implanting prosthetic, maintain normal bone nutrition, the nutrition reducing prosthetic surface is blocked, stress energy is made to be transmitted to the depth aspect of bone more uniformly, reduce stress shielding, stress is concentrated, nutrition is blocked and tension stress obstacle, can effectively prevent super big stress from concentrating the generation of the micro-fracture caused, prevent osteanabrosis and bone resorption, also the stress conductive impairment problem that the elderly's natural bone atrophy osteoporosis causes can be resolved, thus reach and make it closely surround among the stronger overall sclerotin of self-assembling formation, whole stress conductive plate face can both be integral with Integrated implant, unite two into one, solve the biological dispersion conduction of stress simultaneously, the tension stress solving implanting prosthetic biological need first is stablized and nutrition occlusion issue.Again owing to implanting prosthetic is in sclerotin, it is possible to effectively tension stress and stress being transmitted to cortex of bone or periosteum place, external force can be produced certain nervosa perception by patient, becomes the implanting prosthetic that subjectivity has mechanics irritability. implanting prosthetic can be used alone, can combinationally use, more can as several the combination prostheses supporting leg and tension draws leg of big articular prosthesis, what reach prosthetic surface also can reach the fixing powerful support effect in four directions without bone attachment, likeness in form is the dried up high drilling unit risen on sea, even if the prosthese that the bone of prosthese surrounding dissolves with bone resorption under loosening state, not only do not loosen the holding that can also complete firmly implanting prosthetic for a long time support and be satisfied with the performance of function, the Cranial defect that section such as malignant bone tumor is formed after cutting, the defect of joint defect or dry bone, the bridge joint prosthese that a support frame is put can be carried out, become the implanting prosthetic that long-term tight function is satisfied, or become the disposable of one would be set for life and exempt from jointing repair prosthesis: the biological power conduction artificial prosthesis of three D.
