Laparoscopic Tool Calibration

  |  
Application Summary
Minimally Invasive Surgery (MIS) and Single Port Access Surgery (SPAS) have dramatically reduced the risk and recovery time for patients for undergoing tumor extraction, heart valve and artery repair, and in-vitro fertilization. Whether performed with a robotic surgical system or with the trained hands of a surgeon, precision instrumentation is required to work with the delicate tissues of the patient while providing a precise, secure grip without exerting excess force. The forces applied with robotic instrumentation must be calibrated so that visual and haptic feedback mechanisms report the correct applied forces during surgery. Handheld instrumentation requires verification of the applied forces so the tactile sensations felt by the surgeon are predictable and consistent. Here we will demonstrate the verification and calibration of the jaws of a laparoscopic instrument.
Products in Use
Miniature Load Button Load Cell (LLB Series) paired with Instrumentation (IPM650, IHH500, or USB Solutions) and SENSIT™ Test and Measurement Software. View Product Details
Load Cell - Laparoscopic Tool Calibration
How it Works
  1. Load cells enable medical professionals to verify that clamping tools apply the appropriate amount of force before they are used in surgery.
  2. In this application, FUTEK’s Miniature Load Button Load Cell (LLB130) is mounted to the grasping tip of a laparoscopic hand instrument. The load cell records force measurements, which can be used to calibrate the tool.
  3. Load feedback can be displayed on either FUTEK’s IHH500 or IPM650 digital displays, or streamed through USB to a PC. This data can then be examined to determine if the tool is suitable for operation or if it needs to be adjusted.
  4. Pairing the SENSIT Test and Measurement Software with any of FUTEK’s instruments provides the user with the ability to data log the measurements and store them for record keeping or calibration history.
