Embodiment Construction

[0019] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0020] Such as Figure 1-8 As shown, a combined embracing bone setter includes two semicircular bone sets 2, and a number of anti-skid thorns 6 are provided at both ends of the two semicircular bone sets 2, the purpose is to prevent the entire embracing bone setter from axially moving on the tubular bone. slide. The bone plate 2 includes a bone plate crossbeam 10 and an embracing arm 5 below the bone plate crossbeam 10. The two bone plate crossbeams 10 are fixed at the fracture site of the tubular bone by a combination of serrations 7 or other combinations, wherein the serrations 7 can effectively prevent the two halves from The bone plates move axially relative to each other. The two bone plates 2 are fastened by the fixing plate 1, wherein the fixing plate 1 is a hollow structure with an inner lower end opening, and spreader arms 11 are arranged on both sides of t...

Abstract

The invention relates to a combined surrounding bone connector, which comprises two semi-circular bone connecting plates, wherein each bone connecting plate comprises a bone connecting plate cross beam and a surrounding arm arranged under the bone connecting plate cross beam; the two bone connecting plate cross beams adopt a sawtooth combination mode or other combination modes; and the two half bone connecting plate cross beams are fastened through a plurality of fixing plates. The combined surrounding bone connector has the characteristics that the implantation and the taking-out are easy; the operation time is shortened; and the operation difficulty is lowered. By using the fixing plates connected with the two semicircular bone connecting plates, the bone connecting plates are fastened, and meanwhile, the goal of conveniently taking out the combined surrounding bone connector after the operation due to the self structure characteristics of the combined surrounding bone connector is achieved. Meanwhile, a plurality of fixing plates can be fixed according to the length of the bone connecting plates, so that various specifications can be realized. The combined surrounding bone connector can be used for treating different kinds of tubular bone fractures; and the structure is simple.

Description

technical field [0001] The invention belongs to implantable medical devices, in particular to a combined embracing bone adapter. Background technique [0002] In orthopedic surgery, memory alloy embracing bone connectors are often used to deal with various tubular bone fractures, especially for comminuted fractures. The implantation process of the memory alloy embracing bone set is simple, the fixation is firm, and the elastic modulus is similar to that of human bone. However, due to the structural characteristics of the currently used memory alloy embracing bone set, it is difficult for doctors to remove the bone set. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a combined embracing bone set that is easy to implant and take out, shortens the operation time, and reduces the difficulty of the operation in view of the difficulty in taking out the memory alloy embracing bone setter in the prior art. [0004] Ado...
