In laparoscopic surgeries different stapling devices are widely used. However, with such devices tactile sensitivity is badly hindered. This can result in a sub-optimal choice of stapler cartridge, which leads to improper healing of the tissue and even mortality in severe cases. The quantitative analysis of the tissue which we want to staple would help the surgeon choose the optimal cartridge.
A 3D force sensors of the Microsystems Laboratory of HUN-REN CER MFA were integrated into a high precision stepper motor system. The measurement system was applied on resected human GI tissue in the Uzsoki Street Hospital. Thickness of the compressed tissue can be calculated from the recorded force vs. displacement curves.
