Abstract

The invention discloses an acrylic cement fixation screw and an acrylic cement injection device. The acrylic cement injection device comprises a controller, a connecting rod, an injection syringe andthe acrylic cement fixation screw;the controller is provided with an operation channel, and the connecting rod is provided with an injection channel; the acrylic cement fixation screw is connected with one end of the controller, one end of the connecting rod extends into the operator channel of the controller, and the end of the connecting rod is in contact with the screw tail of the acrylic cement fixation screw; and the other end of the connecting rod is connected with the injection syringe. According to the acrylic cement fixation screw, acrylic cement can be well fixed to avoid postoperative displacement of the acrylic cement, meanwhile, zero incision is achieved after operation of the acrylic cement fixation screw, the screw is completely located in a vertebral pedicle of a diseased vertebra, muscle or skin abrasion is avoided, and side effects and influences on patients are avoided.

Description

technical field [0001] The invention belongs to the technical field of orthopedic surgery auxiliary instruments, in particular to a bone cement fixing screw and a bone cement injection device. Background technique [0002] With the progress of population aging, the annual incidence of osteoporotic thoracolumbar fractures is about 30%. When patients experience mild trauma and experience pain and kyphosis again after a period of no obvious symptoms for several months or even years, This type of osteoporotic thoracolumbar fracture is called Kummell's disease, and imaging shows bone defects in the vertebral body of the spine. The main clinical manifestations of Kummell's disease are significantly worse pain than before, especially when standing up, standing, and walking, and vertebral body collapse, progressive kyphosis, and even neurological damage, which seriously affect the quality of life of patients. With the continuous aggravation of aging in my country, the number of pat...
