Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
184 words
A handswitch adapter for use with bipolar forceps, the hand switch adapter comprising a handswitch adapter base and an adapter extension, the handswitch adapter base formed of an electrically nonconductive material and including a tubular handswitch adapter connector physically open at one end and extending from the handswitch adapter base in integral right angle relation thereto, the adapter extension being formed of a coaxial, electrically conductive material and engaged to the open end of the handswitch adapter connector, the adapter extension having a free end remote from the handswitch adapter connector, the free end including a reed microswitch, the reed microswitch being electrically connected to the adapter extension, the handswitch adapter base having a front face and a rear face, a pair of spaced through holes formed therethrough and a terminal pin extending from the rear face thereof in a direction opposite from that toward which the adapter extension extends, the handswitch adapter electrically connected to the terminal pin, the adapter extension having coaxial conductors, one of the conductors connected to the terminal pin, the other conductor connected to one of the through holes.
Claim 2
Dependent Claim
184 words
A handswitch adapter for use with bipolar forceps, the hand switch adapter comprising a handswitch adapter base and an adapter extension, the handswitch adapter base formed of an electrically nonconductive material and including a tubular handswitch adapter connector physically open at one end and extending from the handswitch adapter base in integral right angle relation thereto, the adapter extension being formed of a coaxial, electrically conductive material and engaged to the open end of the handswitch adapter connector, the adapter extension having a free end remote from the handswitch adapter connector, the free end including a reed microswitch, the reed microswitch being electrically connected to the adapter extension, the handswitch adapter base having a front face and a rear face, a pair of spaced through holes formed therethrough and a terminal pin extending from the rear face thereof in a direction opposite from that toward which the adapter extension extends, the handswitch adapter electrically connected to the terminal pin, the adapter extension having coaxial conductors, one of the conductors connected to the terminal pin, the other conductor connected to one of the through holes.
Claim 3
Dependent Claim
280 words
The combination of a handswitch adapter and bipolar forceps, the bipolar forceps comprising first and second tines formed of a conductive material, the first and second tines each having a tip and having a terminal end remote from its tip, each of the terminal ends formed into a connector pin, the first and second tines in substantially spaced relation to each other and connected adjacent the connector pins by an insulating instrument cup, the connector pins extending beyond the instrument cup, the hand switch adapter comprising a handswitch adapter base and an adapter extension, the handswitch adapter base formed of an electrically nonconductive material and including a tubular handswitch adapter connector physically open at one end and extending from the handswitch adapter base in integral right angle relation thereto, the adapter extension being formed of a coaxial, electrically conductive material and engaged to the open end of the handswitch adapter connector, the adapter extension having a free end remote from the handswitch adapter connector, the free end including a reed microswitch, the handswitch adapter base having a front face and a rear face, a pair of spaced through holes formed therethrough and a terminal pin extending from the rear face thereof in a direction opposite from that toward which the adapter extension extends, the connector pins extending through the holes formed in the handswitch adapter base in spaced, parallel relation with the terminal pin, the adapter extension in spaced relation to the first and second tines, the handswitch adapter electrically connected to the terminal pin, the adapter extension having coaxial conductors, one of the conductors connected to the terminal pin, the other conductor connected to one of the through holes.
