Abstract
A control device (1) for an electrosurgical instrument (2), in particular a high-frequency sealing instrument, including a fixed handle part (3), a movable handle part (4), an activation element (5) for activating a current flow, in particular a first type, preferably a sealing current, wherein the activation element (5) is or can be adjusted between a deactivation position and at least one activation position when the movable handle part (4) is actuated, wherein, when the movable handle part (4) is actuated, the activation element (5) is or can be adjusted about an axis of rotation (7).
Claims15
A control device (1) for an electrosurgical instrument (2), the control device comprising:
- a fixed handle part (3);
- a movable handle part (4);
- and
- an activation element (5) configured to activate a current flow, wherein the activation element (5) is adjustable or adjusted about a pivot point from a deactivation position into at least one activation position through actuation of the movable handle part (4), wherein the movable handle part (4) is in mechanical operative connection with the activation element (5), and the activation element is configured such that a current activated by the activation element flows or is adapted to flow through the activation element.
A control device (1) for an electrosurgical instrument (2), the control device comprising:
- at least a fixed handle part (3);
- a movable handle part (4);
- an activation element (5) configured to activate a current flow of a first type, wherein the activation element (5) is adjustable or adjusted from a deactivation position into at least one activation position through actuation of the movable handle part (4), and the movable handle part (4) is in mechanical operative connection with the activation element (5);
- and
- at least one switching element (6) for activating a current flow of a second type, the at least one switching element (6) is formed on the movable handle part (4), and the at least one switching element (6) is actuatable by a user independently of an actuation of the movable handle part (4).
A control device (1) for an electrosurgical instrument (2), the control device comprising:
- a fixed handle part (3);
- a movable handle part (4);
- an activation element (5) configured to activate a current flow, the activation element (5) is adjustable or adjusted about a pivot point from a deactivation position into at least one activation position when the movable handle part (4) is actuated, and the activation element is configured such that a current activated by the activation element flows or is adapted to flow through the activation element, wherein the activation element (5) has at least one conductive contact element (8, 27), and the control device (1) has a conductive mating contact surface (9) which, in an activation position, is acted upon by the contact element (8, 27);
- and
- wherein at least one of during an adjustment of the movable handle part (4) over an activation section of a total adjustment path of the movable handle part (4) or as long as the activation element (5) is in the activation position, the contact element (8, 27) is guided slidingly along the mating contact surface (9).
