Embodiment
[0022] like Figure 1-3 As shown, the embodiment of the present invention provides an unequal type compression fusion device, including a proximal pile 1 and a distal pile 2, a main nail 3 is penetrated between the proximal pile 1 and the distal pile 2, and the proximal pile 3 is arranged. 1 and the distal pile 2 have a round and blunt head, the tail end is in an arc-shaped depression, and a blind end threaded hole of a certain depth is opened in the middle. Auxiliary pile holes 7 penetrate and are provided with auxiliary piles 4. The above-mentioned parts of the structure are all made of metal or alloy. The above-mentioned main nails 3, proximal piles 1, distal piles 2, and auxiliary piles 4 are combined to form an unequal assembly. The structure is used for compression between the two bone surfaces and connection and fixation of the two bone surfaces.
[0023] In the present invention, the proximal pile 1 and the distal pile 2 are respectively implanted into the two bone su...

The invention provides an inequality type pressurization fusion device, and relates to the technical field of fusion fixation or pressurization fixation between two bone surfaces. The inequality type pressurization fusion device comprises a near-end pile and a far-end pile, a main nail is arranged between the near-end pile and the far-end pile in a penetrating mode, auxiliary pile holes are formed in the near-head end and the near-tail end of the near-end pile in a penetrating mode, a steel wire groove is annular, and a steel wire is arranged between the outer diameters of the steel wire groove. The main nails are arranged in the main nail holes, with the internal threads, of the near-end pile and the far-end pile respectively, the two or more auxiliary piles are arranged in the auxiliary pile holes of the near-end pile and the far-end pile, and then the auxiliary piles are connected and fixed through the steel wires, so that the fusion fixing effect on the two bone surfaces can be achieved. And the pressurizing effect between the two bone surfaces and the locking connection of the whole inequality type pressurizing fusion device are generated, so that the osseointegration growth speed between the bone surfaces can be increased, the risks of bone disconnection, fusion failure and implant failure are reduced, and the overall rehabilitation speed is accelerated.
Description
technical field [0001] The invention relates to the technical field of fusion fixation or pressure fixation between two bone surfaces, in particular to an unequal pressure fusion device. Background technique [0002] In clinical practice, there are often situations where pressure fixation or fusion between two bone surfaces is required, such as the fixation between fracture ends and the fusion between articular surfaces. , First, the articular cartilage of the joint needs to be removed, so that the bone can be exposed, and then the exposed bone is combined, and the combined bone is fixed by borrowing plaster and other fixing tools. live. [0003] Most of the existing internal fixators are plate screws or intramedullary nails, which often have insufficient compression strength, or due to osteoporosis and insufficient bone mass, resulting in plate and screw fracture, internal fixation failure, delayed union of the bone surface or bone insufficiency. connection and other risk...
