Description

technical field

[0001] The design of the invention relates to a medical device, in particular to an implantable nickel-titanium temperature memory alloy orthopedic resetter for reduction and reinforcement of spinal vertebral body compression fractures. Background technique

[0002] Vertebral compression fractures of the spine are a common disease, and there are different natures and types of vertebral fractures at different ages. The traditional treatment of vertebral compression fractures is the posterior short-segment pedicle screw technique based on the three-column theory of the spine. The screw is implanted into the normal pedicle adjacent to the upper and lower sides of the affected vertebra. The "stretch-compression" principle of the peripheral ligaments of the body was used to reset the affected vertebra; the internal fixation was removed after the fracture healed, and two operations were performed.

[0003] Posterior pedicle screw technology has been clinically use...
