Stazer

A stazer was a handheld energy weapon that was used within the Constant Division in the 67th century.

A couple of stazers were kept aboard the hospital ship Tsuranga, which were used by Yasmin Khan and Ronan against a Pting. Though they could only stun the Pting for a few seconds, Yasmin was able to use a MedBlanket to contain it within that time. (TV: The Tsuranga Conundrum)
