An apparatus for surgical procedures, the apparatus comprising: a body (23, 523) having a longitudinal axis and a connection opening at a first end of the longitudinal axis, the connection opening including an electrical connection to an electrical circuit maintained within the body (23, 523) and an air path (60, 166) extending through the longitudinal axis of the body (23, 523); a tube assembly (27; 28; 527) having a distal end (35; 36) and a mating end along a tube longitudinal axis, the tube assembly (27; 28; 527) having a vacuum inlet (38; 39) circumscribing an electrode (26, 526) extending from the distal end (35; 36), the vacuum inlet (38; 39) being operable for receiving surgical smoke, the vacuum inlet (38; 39) being fluidly connected to an air tube extending through the tube longitudinal axis, the mating end operable to be removably affixed to the connection opening, thereby connecting the electrode (26, 526) with the electrical connection and the air path (60, 166) with the air tube; and a first button (41; 541) arranged on an external surface of the body (23, 523) operable for controlling a flow of current to the electrode (26, 526) at a first level; wherein the tube assembly (27; 28; 527) operable to slidably move to a plurality of locations within the body (23, 523), wherein each one of the plurality of locations vary a length of the tube assembly (27; 28; 527) extending from the body (23, 523), wherein, in an interference position, the tube assembly (27; 28; 527) is locked at one of the plurality of locations relative to the body (23, 523), and wherein, in an open position, the tube assembly (27; 28; 527) is unlocked to slidably move relative to the body (23, 523); and wherein the electrode (26, 526) remains in electrical contact with the electrical connection at each one of the plurality of locations to receive the flow of current from the electrical circuit at each one of the plurality of locations; characterised by a lever pivotally affixed to the body (23, 523) by a hinge, the lever operable to pivot about the hinge to and from the interference position and the open position, thereby locking or unlocking the tube assembly (27; 28; 527) relative to the body (23, 523); wherein, when the lever is pushed towards the body (23, 523), a portion of the lever below the hinge creates interference and engages with the surface of the air tube such that the tube assembly (27; 28; 527) is locked; and wherein, when the lever is raised away from the body (23, 523), the portion of the lever below the hinge rotates away from interference with the surface of the air tube such that the tube assembly (27; 28; 527) may be moved relative to the body (23, 523). a body (23, 523) having a longitudinal axis and a connection opening at a first end of the longitudinal axis, the connection opening including an electrical connection to an electrical circuit maintained within the body (23, 523) and an air path (60, 166) extending through the longitudinal axis of the body (23, 523); a tube assembly (27; 28; 527) having a distal end (35; 36) and a mating end along a tube longitudinal axis, the tube assembly (27; 28; 527) having a vacuum inlet (38; 39) circumscribing an electrode (26, 526) extending from the distal end (35; 36), the vacuum inlet (38; 39) being operable for receiving surgical smoke, the vacuum inlet (38; 39) being fluidly connected to an air tube extending through the tube longitudinal axis, the mating end operable to be removably affixed to the connection opening, thereby connecting the electrode (26, 526) with the electrical connection and the air path (60, 166) with the air tube; and a first button (41; 541) arranged on an external surface of the body (23, 523) operable for controlling a flow of current to the electrode (26, 526) at a first level; wherein the tube assembly (27; 28; 527) operable to slidably move to a plurality of locations within the body (23, 523), wherein each one of the plurality of locations vary a length of the tube assembly (27; 28; 527) extending from the body (23, 523), wherein, in an interference position, the tube assembly (27; 28; 527) is locked at one of the plurality of locations relative to the body (23, 523), and wherein, in an open position, the tube assembly (27; 28; 527) is unlocked to slidably move relative to the body (23, 523); and wherein the electrode (26, 526) remains in electrical contact with the electrical connection at each one of the plurality of locations to receive the flow of current from the electrical circuit at each one of the plurality of locations; characterised by a lever pivotally affixed to the body (23, 523) by a hinge, the lever operable to pivot about the hinge to and from the interference position and the open position, thereby locking or unlocking the tube assembly (27; 28; 527) relative to the body (23, 523); wherein, when the lever is pushed towards the body (23, 523), a portion of the lever below the hinge creates interference and engages with the surface of the air tube such that the tube assembly (27; 28; 527) is locked; and wherein, when the lever is raised away from the body (23, 523), the portion of the lever below the hinge rotates away from interference with the surface of the air tube such that the tube assembly (27; 28; 527) may be moved relative to the body (23, 523).
