SPACER FOR USE IN A SURGICAL OPERATION FOR SPINOUS PROCESS OF SPINE

A spacer for a surgical operation for a spinous process of a spine is provided to prevent an unnecessary damage of a vertebra and reduce an operation time by fixing the spacer between spinous processes of a spine using a shape-memory alloy transformed by body heat. A spacer for a surgical operation for a spinous process of a spine includes a pair of prop parts(101), and a connection part of a shape- memory alloy(100). The pair of prop parts support the pair of spinous processes to be an object of the surgical operation. The connection part of the shape-memory alloy connects the pair of prop parts and provides an expansion force for the prop parts to support the spinous processes by being transformed toward a direction mutually separating the pair of prop parts by body heat.
