ABSTRACT:
A holder (16) for releasably holding needle electrodes (18). The holder (16) includes a body (26) having a base slidably mounted within the body. Depressing the base into the body (26) releases a gripping assembly (50) located within the body (26) allowing a needle electrode (18) inserted into the holder to be removed. Releasing the base (24) causes the gripping assembly to engage a needle electrode inserted into the holder. The gripping mechanism (50) includes a chuck (60) having an opening sized to receive the needle electrode (18). The chuck engages a ferrule (73) that depresses the jaws (70) of the chuck (68) radially inwardly with respect to each other to reduce the size of the opening in the chuck thus holding a needle electrode (18) inserted into the chuck (68).
