Assembled pressure-applying nail-pile fusion device

Abstract

The invention provides an assembled pressure-applying nail-pile fusion device. The assembled pressure-applying nail-pile fusion device comprises a nail arm, a pile arm, a connecting lock pin and a pressure applying clamp, wherein the nail arm and the pile arm form an inserted assembling structure; and the pressure applying clamp applies pressure to the inserted assembling structure and is connected and fixed through the connecting lock pin. All parts of the assembled pressure-applying nail-pile fusion device are combined and connected, pressure application between two bone surfaces can be effectively implemented and controlled, the two bone surfaces are connected and fixed, the bone fusion efficiency can be improved, the probability of breakage and failure of an implant is reduced, and the rehabilitation process is accelerated.

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...
