Abstract

The invention discloses a bone cement fixation device and method. The fixation device comprises a screw, a connector and a push rod, the screw comprises a screw head and a screw body, a bone cement channel is formed in the screw body, a groove is formed in the screw head, the connector is of a cylindrical structure, and the lower end of the connector is matched with the groove in shape; a push rodis inserted into the cylinder cavity of the connector; the fixation method comprises the following steps that the screw is screwed into a vertebral body, the lower end of a connector is connected tothe groove, the cylinder cavity of the connector is communicated with a bone cement channel, bone cement is injected into the cylinder cavity, a push rod is inserted into the cylinder cavity, the pushrod is pushed downwards, and part of the bone cement is injected into the vertebral body through the bone cement channel; and the bone cement channel is filled with the other part of the bone cement.According to the bone cement fixation device and method, bone cement in the vertebral body can be well fixed, and therefore the treatment effect is guaranteed.

Description

technical field [0001] The invention relates to the medical field, in particular to a device and method for fixing bone cement. Background technique [0002] In the treatment of orthopedic diseases in patients with osteoporosis (such as elderly patients), vertebral body diseases are the most common, and medical screws are usually used, such as pedicle screws and bone screws. Fix the medical screws, so the doctor will first inject bone cement into the patient's vertebral body, and then insert the medical screws into the bone cement in the vertebral body after the bone cement solidifies, so the medical screws are fixed on the patient's vertebral body. During the actual treatment process, with the movement of the patient, the bone cement will be displaced in the vertebral body, which will affect the fixation effect of the medical screws and further affect the treatment effect. Contents of the invention [0003] The technical problem to be solved by the present invention is t...
