Intramedullary nail cement putting-aside mold for long bone fracture and operation method thereof

Abstract

The invention discloses an intramedullary nail cement putting-aside mold for a long bone fracture and an operation method thereof. The intramedullary nail cement putting-aside mold comprises an outermold and an outer mold which are mutually cooperated, an inner mold and an inner mold are respectively embedded in the cavities of the outer mold and the outer mold, an inner mold cavity and an innermold cavity are respectively arranged in the inner mold and the inner mold, which are adapted to the shape of the intramedullary nail for the long bone fracture, the outer mold, the inner mold, the inner mold and the outer mold are combined to form a fixed mold, and a locking screw fixing device is used. The invention also discloses an intramedullary nail cement putting-aside mold operation method. The mold has the advantages of simple structure and easy operation, can keep matching degree of a positioner, and has short production time and low cost.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a long bone fracture intramedullary nail bone cement settling mold and an operation method thereof, in particular to a "antibiotic bone cement intramedullary mold" for infection after long bone fracture intramedullary nail fixation. 3D printed mold for nails. Background technique [0002] Intramedullary nailing has minimal invasiveness and mechanical advantages, and is currently the gold standard for the treatment of long bone fractures. However, infection still occurs after intramedullary nailing, and the incidence of infection after intramedullary nailing for tibial fractures is 1% to 14%; in patients with nonunion fractures after intramedullary nailing for tibia and femur, the incidence of infection is as high as 30% . This complication causes great pain and heavy economic burden to patients. Infection after long intramedullary nailing is one of the more difficult pro...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a long bone fracture intramedullary nail bone cement settling mold and its operating method, which solves many problems in the treatment of bone cement stick infection after the existing long bone fracture intramedullary nail fixation, bone cement stick It is simple to make, similar to intramedullary nails, and the Kirschner wire in the cement rod does not need to be pre-bent. After filling the bone marrow cavity, the surrounding space is uniform and has a certain fixation strength. Combined with external fixation, early functional exercise can be achieved, and the curative effect can achieve the desired goal.
