Laser scalpel

The laser scalpel was a specialized medical instrument used for creating incisions in various tissues. It used a finely-tuned laser beam to make cuts. This device was available in different wavelengths for varied cutting strength and depth.

In 2367 a laser scalpel was used by Doctor Beverly Crusher to remove the Trill symbiont Odan from the body of his current host and transplant it into the body of Commander Riker. 

The laser scalpel was the term used from the 2260s, until the 2370s, when it was replaced by the exoscalpel. 

The laser scalpel was one of several devices incorporated into the servo-armatures of Borg medical repair drones. 

Captain Janeway used a laser scalpel to extract a Borg cortical node. Later she used one to force a group of alien salvagers to stand down their weapons.
