Vertebra Dilator

The vertebra dilator is used to establish a working channel for the injection of bone cement into the vertebral body. It is primarily used in clinical practice in conjunction with a vertebral bone puncture needle, as well as a hand drill and bone cement filler. After puncturing the patient's vertebral body using the vertebral bone puncture needle, the expander is inserted using a guide wire to enlarge the working channel, facilitating the entry of subsequent instruments for treatment. SCW vertebra dilator is mainly composed of an expander and a working cannula.
