摘要:An assembly for performing an electrosurgical procedure. A cannula includes acannula hub defining a middle bore having a smaller diameter than a proximal bore. An
electrode includes an electrode head having an outer diameter smaller than the proximalbore and greater than the middle bore. A syringe includes a syringe head having a lengthsufficient to extend past the proximal bore, and an outer diameter sized to engage themiddle bore to form an annular seal at an interface between the syringe and the cannula.A step may define a transition surface between the proximal bore and the middle bore,and at least one notch may be within the step to maintain fluid communication betweenthe middle bore and the proximal bore when the electrode head is engaging the step.The cannula head may include first and second locking features configured to engage thesyringe and electrode, respectively.
