摘要：
Various embodiments described herein are directed to curved ultrasonic blades. For example, a curved ultrasonic blade may comprise a proximally positioned straight section and a distally positioned curved section. The curved ultrasonic blade may be positioned within a shaft extending along a longitudinal axis. The curved ultrasonic blade may be translatable relative to the shaft. The curved section of the curved ultrasonic blade may translate from a first position where the curved section is at least partially contained within the shaft to a second position where the curved section curves away from the longitudinal axis. The curved section may define a radius of curvature that increases as the curved section curves away from the longitudinal axis. In another example, the curved ultrasonic blade may comprise a proximally positioned first curved section and a distally positioned second curved section. The curvature of the first curved section may be opposite of the curvature of the second curved section.
