Technical field

The present invention relates to a kind of joint that is arranged on the 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 beyond doubt medical expert Ilizarov of Russia invention, hole ring type external fixator and fine steel needle tension technology, make the bone external fixator on the primitive meaning, in mechanical function mode and Mechanobiology performance quality variation, performance of control raising have occured, indication is more extensive, is the major progress of bone external fixator technical field.The technology of Ilizarov has also excited countless orthopedists to the interest of study, research and the application of bone External technique, thereafter U.S. Dror Paley has write " orthopedics's principle ", creative the CORA concept is applied to bone outward among fixing the rescuing, make bone outward fixedly straightening technique making substantial progress aspect standardization and the 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 recognize the bone external fixator open, using value in the infected fracture, developed a kind of tubulose external fixator.American J Charles Taylor in 1994 (charles. Taylor) etc. the 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 six telescopic connecting rods are connected obliquely on near-end and the distal loop and can rotate freely at the junction point place, 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, form an integral body (if with 5 connecting rods then system is unstable, if with 7 connecting rod system would be subject to excessive restriction), total is unusually firm.Taylor's space frame is as long as regulate the wherein length of a connecting rod, a ring will another encircle change position relatively, connect base surface to 6 pillars of platform, its length, spatially-variable, by means of robotics and parallel mechanics, the length of regulating 6 connecting rods by the instruction numeral of computer export changes the steric configuration of Taylor's space frame, reaches that fracture site resets, the orthopedic or purpose that prolongs.

The treatment fracture is when (after comprising that the skeleton deformity osteotomy is orthopedic), how to implement reasonably fixing, can only be according to the biological regularity of knitting, analyze, estimate, explore rational rigidity of fixation, and carry out technological innovation with this, and be not only the reasonability around the study on fixation methods rigidity of fixation, so since the nineties in 20th century, Chinese scholar creativeness has proposed the regeneration reconstruction theory and has been basis, the bone External technique system take cybernetics as criterion.

Now, the applicant has proposed a kind of " the adaptability rigidity concept of fracture fixation ", i.e. the adaptability rigidity of fixation according to " orthopaedics Natural Reconstruction theory ".Described adaptability rigidity of fixation, the phalanges external fixator keep the reduction of the fracture stable in, according to the original growth mode of bone embryo, interim best rigidity of fixation is provided, take full advantage of the adaptive control of bone counter stress, adjust growth and the absorption of bone, promote the process of union of fracture, finish the optimized reconstruction of bone function, until knitting returns to the most perfect degree, in other words, be exactly 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.Sum up thus: the 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, to External technique clinically rational Application the theoretical direction that is of practical significance is provided.

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 satisfy fracture fixation, healing, the biological process of rebuilding, it is strong fixing namely to be difficult to satisfy the fracture early implementation, 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 when (existing simultaneously such as several problems for the treatment of that need), it is not enough that the motility of Taylor's space frame seems, and must computer the instruction numeral of the output length of regulating 6 connecting rods, change thus the steric configuration of support, reaching fracture site resets, orthopedic or prolong purpose, so lack function adaptability, certain limitation arranged when clinical practice.2, Taylor's space frame can only connect with 6 bars and supports two rings, form an integral body, if with 5 bars then system is unstable, if with 7 bars then 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.
