Problems solved by technology

[0002] The existing technologies for pressurizing and fixing the two bone surfaces mainly include cancellous bone screws, saddle nails, external fixators, plate screws, etc. The defect is that the fixation strength is insufficient, and the fixation mechanical strength cannot meet the requirements of osteoporosis. requirements, there is no compressive effect on the bone surface, so there is a certain degree of risk of delayed union and disunion of the bone surface

Embodiment Construction

[0021] There are many conditions that require compression and fixation between two bone surfaces, such as arthrodesis, and other situations that require a connection between bone surfaces. Currently there are cancellous bone screws, saddle nails, external fixators, plate screws, etc., but all of them have insufficient fixation strength, and the mechanical strength of fixation in the case of osteoporosis cannot meet the requirements, and there is no compression effect on the bone surface. There is a certain risk of delayed union and disunion of the bony surfaces. In order to solve such problems, the present invention designs a modular pressurized nail-pile fusion device, which can conveniently realize pressurized fixation between bone surfaces, reduce the risk of delayed bone union, and improve the fixation strength.

[0022] Below in conjunction with accompanying drawing, the realization mode of the present invention is described in detail by specific embodiment:

Abstract

The invention provides a combined pressurizable nail-pile fusion device, the combined pressurizable nail-pile fusion device includes a nail arm, a pile arm, connecting locking nails and pressure clamps, the nail arm and pile The arms form a plug-in assembly structure, and the pressurizing pliers pressurize the plug-in assembly structure and are connected and fixed by the connecting locking nails. Combining and connecting the various parts of the modular pressurizable nail-pile fusion device of the present invention can effectively implement and control the pressure between the two bone surfaces, as well as connect and fix the two bone surfaces, which can improve the efficiency of bone fusion , reduce the probability of implant breakage and failure, and speed up the recovery process.

Description

technical field [0001] The invention belongs to the technical field of pressurizing and fixing between two bone surfaces, in particular to an assembled pressurized nail-pile fusion device. Background technique [0002] The existing techniques for pressurizing and fixing between two bone surfaces mainly include cancellous bone screws, saddle nails, external fixators, plate screws, etc., but the disadvantage is that the fixation strength is insufficient, and the fixation mechanical strength cannot meet the requirements of osteoporosis. Requirements, there is no compressive effect on the bone surface, so there is a certain degree of risk of delayed union and disunion of the bone surface. There are a wide range of situations that require the use of this technology, such as arthrodesis, internal fixation of fractures, etc. Therefore, there is an urgent need for a connectable and modular pressurizable fusion device that can easily adjust the pressure between the two bone surfaces...
