HANDLE AND POWER CORD ASSEMBLIES FOR BIPOLAR ELECTROSURGICAL DEVICES

摘要

Bipolar electrosurgical devices may include a handle assembly configured to control movement of components of the electrosurgical device to perform an electrosurgical procedure and a power cord assembly configured to electrically connect the bipolar electrosurgical device with a power source. For bipolar sphincterotomes, an active portion of the handle assembly may include a first active member that contacts and slides across a second active member as the gripping portion moves about a handle stem component of the handle assembly. The power cord assembly may include a pair of return contacts that are shorted together when connected with the handle assembly, which in turn may deactivate an alarm output by the power source.
