摘要：
An interface joint with one or both of a needle actuation mechanism or anintegrated shaft rotation mechanism. Theinterface joint compnses a flexible shaft between a housing and an electrosurgical instrument, e g for conveying power and/or fluid therebetween. The needle actuation mechanism compnses an actuation rod extendingout of the housing and an actuator movably mountedon the housing The shaft rotation mechanism comprises a rotation actuatorrotatably mounted on the housing and operably coupledto the flexible shaft. Providing an integrated shaft rotation mechanism mayobviate the need for a separate torque transmission unitThe improved needle actuation mechanism may use a pivoting connection toenable longer needle extension distances to be achievedfor a given actuation distance
