Description
Technical field
The present invention relates to a kind of joint being arranged on exter-nal fixer, and a kind of exter-nal fixer.
Background technology
In the process of medical skill modernization, the material of exter-nal fixer obtains significant progress with configuration aspects, the hole ring type external fixator of the prominent invention of Russia medical expert Ilizarov beyond doubt, hole ring type external fixator and fine steel needle tension technology, make the exter-nal fixer in primitive meaning, there occurs that quality change, performance of control improve in mechanical function mode and Mechanobiology performance, indication is more extensive, is the major progress of exter-nal fixer technical field.The technology of Ilizarov also excites countless orthopedist to the study of bone External technique, the interest studying and apply, thereafter U.S. Dror Paley has write " orthopedics's principle ", creative CORA concept being applied to, among the rescuing of bone extenal fixation, makes bone extenal fixation straightening technique make substantial progress in terms of standardization and digitized.Meanwhile, the research of orthopedic instruments also has a rapid progress: 1984, and Bastiani etc. has invented a kind of monolateral axle dynamic external fixator, simplifies to have grasped and makees difficulty, is the more a kind of exter-nal fixer of domestic and international application；AO school also identifies the exter-nal fixer using value opening, in infected fracture, have developed a kind of tubulose external fixator.American J Charles Taylor in 1994 (charles. Taylor) et al. on the basis of Ilizarov annular external fixator, Curve guide impeller becomes " Spatial infrastructure " external fixator (Taylor Spatial Frame of numeral, it is called for short TSF), " Spatial infrastructure " external fixator is a kind of hole ring type external fixator six telescopic connecting rods being connected obliquely and can rotating freely on proximally and distally ring and at junction point, and this hole ring type external fixator is also referred to as " Taylor's space frame ".
Taylor's space frame has six connecting rods that can regulate length, and the length of each connecting rod can directly read, 6 connecting rods connect two rings of support, (if by 5 connecting rods, system is unstable to form an entirety, if by 7 connecting rods, system is excessively limited), total is abnormal firm.If the length of Taylor's space frame regulation wherein connecting rod, one ring will change position by another ring relatively, connect the base surface 6 pillars to platform, its length, spatially-variable, by means of robotics and parallel mechanics, instruction numeral by computer export regulates the length of 6 connecting rods, changes the steric configuration of Taylor's space frame, reaches fracture site reset, the orthopedic or purpose of prolongation.
During treatment fracture (after including that skeleton deformity osteotomy is orthopedic), how to implement the most fixing, can only be according to the biological regularity of knitting, analyze, evaluate, explore rational rigidity of fixation, and carry out technological innovation with this, and it is not only the reasonability around study on fixation methods rigidity of fixation, so since the nineties in 20th century, based on Chinese scholar creativeness proposes regeneration reconstruction theory, the bone External technique system with cybernetics as criterion.
Now, applicant is according to " orthopaedics Natural Reconstruction theory ", it is proposed that a kind of " the adaptability rigidity concept of fracture fixation ", i.e. adaptability rigidity of fixation.Described adaptability rigidity of fixation, refer to that exter-nal fixer is while maintaining the reduction of the fracture stable, according to bone embryo original growth mode, interim optimal rigidity of fixation is provided, make full use of the adaptive control of bone counter stress, adjust growth and the absorption of bone, promote the process of union of fracture, the optimized reconstruction of complete osteogenesis function, until knitting returns to the most perfect degree, in other words, it is simply that the rigidity of fracture fixation reduces, the dynamic conversion process that biomechanics of bone intensity increases along with the reduction of rigidity of fixation along with the increase of the intensity of knitting.Thus sum up: fracture early implementation is strong fixing, axial and the flexible fastening of combined stress stimulation is provided mid-term, later stage provides balance fixing, this concept meets fracture fixation, the biological process healing, rebuilding, and the most rationally applies External technique and provides the theoretical direction being of practical significance.
nullAlthough the design of Taylor's space frame、Make and reached precision with clinical practice、Standardization and intelligentized degree，But there is also the place not as people's will: 1、Taylor's space frame is difficult to meet fracture fixation、Healing、The biological process rebuild，I.e. it is difficult to meet fracture early implementation strong fixing、Axial and the flexible fastening of combined stress stimulation is provided mid-term、Later stage provides the needs that balance is fixing，Specifically，It is exactly that the fixing rigidity of Taylor's space frame can not change，When running into some especially complex cases (the most several problems needing treatment exist) simultaneously，The motility of Taylor's space frame seems not enough，And the length of 6 connecting rods must be regulated by the instruction numeral of computer export，Thus change the steric configuration of support，Reach fracture site to reset、Purpose that is orthopedic or that extend，So lacking function adaptability，Certain limitation is had when clinical practice.2, Taylor's space frame can only connect with 6 bars and supports two rings, form one entirety, if by 5 bars, system instability, if with 7 bars, system is excessively limited, it is clear that whole system is cured, not only manufacturing cost is high, and uses expensive, adds medical treatment cost.
