Technical field
The present invention relates to a kind of connecting rod being arranged on bone external fixator, and a kind of bone external fixator.
Background technology
In the modern process of medical skill, material and the structure aspects of bone external fixator obtain significant progress, the hole ring type external fixator of the outstanding invention of the medical expert Ilizarov of Russia beyond doubt, hole ring type external fixator and fine steel needle tension technology, make the bone external fixator in primitive meaning, in mechanical function mode and Mechanobiology performance, quality variation, performance of control raising have occurred, indication is more extensive, is the major progress of bone external fixator technical field.The technology of Ilizarov has also excited the interest of study, research and the application of countless orthopedists to bone External technique, thereafter U.S. Dror Paley has write the principle > > of < < orthopedics, creativeness is applied to CORA concept among outer the rescuing of fixing of bone, makes bone fix straightening technique outward and is making substantial progress aspect standardization and digitized.Meanwhile, the research of orthopedic instruments also has rapid progress: 1984, Bastiani etc. invented a kind of monolateral axle dynamic external fixator, and simplify to have grasped and make difficulty, be the more a kind of bone external fixator of domestic and international application; AO school also recognizes the using value of bone external fixator opening, in infected fracture, has developed a kind of tubulose external fixator.American J Charles Taylor in 1994 (charles. Taylor) etc. people on the basis of Ilizarov annular external fixator, improvement is designed to " Spatial infrastructure " external fixator (Taylor Spatial Frame of numeral, be called for short TSF), " Spatial infrastructure " external fixator is a kind of hole ring type external fixator that can rotate freely on near-end and distal loop and at junction point place that six telescopic connecting rods are connected obliquely, and this hole ring type external fixator also claims " 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 be read, 6 connecting rods connect two rings of support, (if with 5 connecting rods, system is unstable to form an entirety, if with 7 connecting rods, system is subject to excessive restriction), total is extremely firm.Taylor's space frame is as long as regulate the wherein length of a connecting rod, ring another ring change position relatively, connect the 6 piece pillars of base surface to platform, its length, spatially-variable, by means of robotics and parallel mechanics, by the instruction numeral of computer export, regulate the length of 6 connecting rods, change the steric configuration of Taylor space frame, reach that fracture site resets, the orthopedic or object that extends.
During treatment fracture (after comprising that skeleton deformity osteotomy is orthopedic), how to implement reasonably 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 be not only the reasonability around study on fixation methods rigidity of fixation, so since the nineties in 20th century, Chinese scholar creativeness has proposed regeneration reconstruction theory for basis, the bone External technique system take cybernetics as criterion.
Now, applicant, according to " orthopaedics Natural Reconstruction theory ", has proposed a kind of " the adaptability rigidity concept of fracture fixation ", i.e. adaptability rigidity of fixation.Described adaptability rigidity of fixation, phalanges external fixator maintain the reduction of the fracture stable in, according to the original growth mode of bone embryo, interim best 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, be exactly that the rigidity of fracture fixation reduces along with the increase of the intensity of knitting the dynamic conversion process that biomechanics of bone intensity increases along with the reduction of rigidity of fixation.Sum up thus: fracture early implementation is strong fixing, flexible fastening axial and that combined stress stimulates is provided mid-term, later stage provides balance to fix, this concept meets the biological process of fracture fixation, healing, reconstruction, and to External technique, rationally application clinically provides the theoretical direction being of practical significance.
Although the design of Taylor's space frame, make with clinical practice and reached precision, standardization and intelligentized degree, but also there is the place not as people's will: 1, Taylor's space frame is difficult to meet fracture fixation, healing, the biological process of rebuilding, be difficult to meet fracture early implementation strong fixing, flexible fastening axial and that combined stress stimulates is provided mid-term, later stage provides balance fixing needs, specifically, be exactly that the fixing rigidity of Taylor's space frame can not change, when running into some complicated especially cases (such as several problems that need treatment exist simultaneously), it is not enough that the motility of Taylor's space frame seems, and must computer the instruction numeral of output regulate the length of 6 connecting rods, change thus the steric configuration of support, reaching fracture site resets, orthopedic or extend object, so lack function adaptability, when clinical practice, there is certain limitation.2, Taylor's space frame can only connect and support two rings with 6 bars, form an entirety, if with 5 bars, system is unstable, if with 7 bars, system is subject to excessive restriction, obviously, whole system has been cured, not only manufacturing cost is high, and uses expensively, has increased medical treatment cost.
