Surgical pencil enabling suction
View Patent ↗Described herein generally are surgical pencils which define a channel to enable suctioning of materials and methods of operating the surgical pencils. Surgical pencils are described comprising: a surgical tool configured to perform one of cutting and coagulation, the surgical pencil having a housing including a channel through the housing and terminating near the surgical tool which enables direct suctioning of a material at a surgery site.
1. A surgical pencil comprising:
a tip formed substantially of a metal 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 includes an elongated tube, a first structure configured to support a proximal portion of the elongated tube and a second structure configured to support a distal portion of the elongated tube and wherein the channel through the housing terminates near the tip which enables direct suctioning of a material at a surgery site, and wherein the metal tip is connected to the elongated tube and the elongated tube is configured to move the tip from an extended to a retracted position.
2. The surgical pencil of claim 1 , wherein the material includes at least one of smoke, blood and tissue.
3. The surgical pencil of claim 1 , which includes a lighting device.
4. The surgical pencil of claim 3 , wherein the lighting device includes an LED light.
5. The surgical pencil of claim 1 , wherein suctioning is not effected by movement of the tip between the extended position and the retracted position.
6. The surgical pencil of claim 1 , wherein suctioning is provided circumferentially around the tip.
7. 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 includes an elongated tube, a first structure configured to support a proximal portion of the elongated tube and a second structure configured to support a distal portion of the elongated tube and wherein the channel through the housing terminates near the tip which enables direct suctioning of materials at a surgical site and allows movement of the tip without disturbing suctioning of material at the surgical site, and wherein the elongated tube is configured to move the tip from an extended to a retracted position; 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.
8. The surgical pencil of claim 7 , which includes:
a cylinder portion configured to removably connect to a housing of the surgical pencil; and
a hose connector.
9. The surgical pencil of claim 8 , wherein the channel is defined by the cylinder portion, the elongated tube, a first structure a second structure, and the hose connector.
10. The surgical pencil of claim 8 , wherein the cylinder portion is configured to house the tip when the tip is in the retracted position.
11. The surgical pencil of claim 8 , wherein the tip extends from the cylinder portion when the tip is in the extended position.
12. The surgical pencil of claim 7 , which includes a connector configured to connect to a separate discharge tube, the separate discharge tube being connected to a separate suction device.
13. The surgical pencil of claim 7 , which includes a lighting device operatively coupled to the processor.
14. The surgical pencil of claim 7 , wherein the tip is attached to the slidable elongated tube.
15. The surgical pencil of claim 7 , wherein suctioning is not effected by movement of the tip between the extended position and the retracted position.
16. The surgical pencil of claim 7 , wherein suctioning is provided circumferentially around the tip.
