Claims21
1-21. (canceled)
A surgical pencil comprising:
- a tip formed substantially of a metal and configured to perform one of cutting and coagulation, the surgical pencil having a housing including a channel through the housing, wherein the channel through the housing terminates near the tip which enables direct suctioning of a material at a surgery site, and wherein the tip is movable within the channel without disturbing suctioning of the material at the surgical site.
A surgical pencil comprising:
- a processor;
- an input device operatively connected to the processor;
- a tip formed substantially of a metal operatively connected to the processor;
- a housing including a channel through the housing, wherein the channel through the housing terminates near the tip which enables direct suctioning of materials at a surgical site and wherein the tip is movable within the channel without disturbing suctioning of material at the surgical site;
- and
- a memory device storing instructions which when executed by the processor, cause the processor, in cooperation with the input device and the memory device, to enable the surgical pencil to operate as one of a cutting device and a coagulation device.
3 more elements
A method of operating a surgical pencil, the method comprising:
- causing a processor to, in response to a selection of a first input device, enable a tip formed substantially of a metal to operate as a cutting device;
- causing the processor to, in response to a selection of a second input device, enable the tip to operate as a coagulation device;
- and
- causing a suction device to, using a channel defined by the surgical pencil, remove material, wherein suctioning is provided circumferentially around the tip.
