Apparatus for sealing electronics from environment in dc powered arthroscopic surgical handpiece with pushbutton actuation

Abstract

A button for actuating a switch in a surgical handpiece. The button is sealed to a bezel, and the bezel is sealed to the handpiece. The button, bezel, and handpiece create a sealed enclosure surrounding the switch to prevent external substances from contacting the switch. Further, a control board for controlling the handpiece is embedded in a cable endcap instead of being housed within the handpiece.

What is claimed as new and desired to be protected by Letters Patent of the United States is: 
     
         1 . A surgical device comprising:
 a handpiece; and   a cable for coupling the handpiece to a console, the cable having an endcap that couples to the handpiece, wherein the endcap includes a control board for the handpiece enclosed therein.   
     
     
         2 . The surgical device of  claim 1 , wherein the handpiece has a male connector. 
     
     
         3 . The surgical device of  claim 2 , wherein the endcap has a female connector that receives the male connector of the handpiece. 
     
     
         4 . The surgical device of  claim 3 , wherein the female connector of the endcap is soldered to the control board. 
     
     
         5 . The surgical device of  claim 3 , wherein the female connector of the endcap is connected to the console through the cable
