Surgical Pencil Enabling Suction

Abstract

Described herein generally are surgical pencils which define a channel to enable suctioning of materials and methods of operating the surgical pencils. In one example embodiment, the surgical pencils perform cutting and coagulation. In one example embodiment, the surgical pencils include a lighting device.

The invention is claimed as follows: 
     
         1 . A surgical pencil comprising:
 a surgical tool configured to perform one of cutting and coagulation, the surgical pencil defining a channel which enables suctioning.   
     
     
         2 . The surgical pencil of  claim 1 , which includes a suction device configured to perform suctioning of a material. 
     
     
         3 . The surgical pencil of  claim 2 , wherein the material includes at least one of smoke, blood and tissue. 
     
     
         4 . The surgical pencil of  claim 1 , which includes a lighting device. 
     
     
         5 . The surgical pencil of  claim 4 , wherein the lighting device includes an LED light. 
     
     
         6 . A surgical pencil comprising:
 a processor;   an input device operatively connected to the processor;   a surgical tool operatively connected to the processor;   a channel configured to enable suction of materials; 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.   
     
     
         7 . The surgical pencil of  claim 6 , which includes:
 (a) a cylinder portion configured to removably connect to a housing of the surgical pencil;   (b) an elongated tube configured to receive and direct the cylinder portion;   (c) a hose connector.   
     
     
         8 . The surgical pencil of  claim 7 , wherein the channel is defined by the cylinder portion, the elongated tube and the hose connector. 
     
     
         9 . The surgical pencil of  claim 7 , wherein the cylinder portion is configured to house the cutting tool when the cutting tool is in a retracted position. 
     
     
         10 . The surgical pencil of  claim 7 , wherein the cutting tool extends from the cylinder portion when the cutting tool is in an extended position. 
     
     
         11 . The surgical pencil of  claim 6 , which includes a connector configured to connect to a separate discharge tube, the separate discharge tube being connected to a separate suction device. 
     
     
         12 . The surgical pencil of  claim 6 , which includes a lighting device operatively coupled to the processor. 
     
     
         13 . A method of operating a surgical pencil including instructions, the method comprising:
 (a) causing a processor to, in response to a selection of a first input device, execute the instructions to enable the surgical pencil to operate as a cutting device;   (b) causing the processor to, in response to a selection of a second input device, execute the instructions to enable the surgical pencil to operate as a coagulation device; and   (c) causing a suction device to, using a channel defined by the surgical pencil, remove material.   
     
     
         14 . The method of  claim 13 , wherein surgical pencil includes the suction device. 
     
     
         15 . The method of  claim 13 , wherein the suction device is separate from the surgical device. 
     
     
         16 . The method of  claim 13 , wherein the material includes at least one of smoke, blood and tissue. 
     
     
         17 . The method of  claim 13 , which includes causing the processor to execute the instructions to operate with a light device to cause the light device to emit light. 
     
     
         18 . The method of  claim 13 , wherein the channel is defined by a housing of the surgical pencil. 
     
     
         19 . The method of  claim 13 , wherein the surgical pencil includes:
 (a) a housing;   (b) a cylinder portion configured to removably connect to the housing;   (c) an elongated tube configured to receive and direct the cylinder portion; and   (d) a hose connector.   
     
     
         20 . The method of  claim 19 , which includes, in response to the surgical pencil being in a retracted state, causing the cylinder portion to house a cutting tool. 
     
     
         21 . The method of  claim 19 , which includes, in response to the surgical pencil being in a retracted state, causing a cutting tool to extend from the cylinder portion.
