Abstract

For a laparoscopic device, the need arises for differentiated buttons to be used that are of similar shape, but have different functionalities for suction and irrigation capabilities. Often times it is necessary for the buttons to be of a similar shape and activate similarly. The manufacturing process for assembling buttons of similar size with conical surfaces can be challenging due to button interchangeability and misalignment.

POKE‐YOKE ALIGNMENT FEATURE FOR BUTTON DESIGN ON A LAPAROSCOPIC DEVICE 

SUMMARY:  For a laparoscopic device, the need arises for differentiated buttons to be used that are of similar shape,  but have different  functionalities  for suction and  irrigation capabilities. Often  times  it  is necessary  for  the buttons  to be of a similar shape and activate similarly. The manufacturing process  for assembling  buttons of  similar  size with  conical  surfaces  can be  challenging due  to button  interchangeability  and  misalignment.    DESCRIPTION:  A  laparoscopic device consisting of a button with a key  feature added  to  the  suction button  flange  is  proposed  to  facilitate  these  unmet  needs  in  the  manufacturing  process. The laparoscopic device consists of an inner manifold containing valves for both irrigation and suction capabilities. The irrigation and suction lines are activated by pressing onto the buttons which connect to the valves. The suction button has a square key feature on the flange that prevents it from fitting in the assembly equipment incorrectly. The key feature on the button flange is indistinguishable to the user,  but, would aid  in  the manufacturing assembly process  to poke‐yoke  the assembly of  the  suction and  irrigation buttons. The  feature would prevent  the  suction button  to be assembled onto  the  irrigation  button  side  by mistake  and  also  help  to  eliminate  button  rotation  during...
