Jaw length and compression pressure distribution. The compression within the jaws of the Caiman® 5 sealing device in comparison to other electrosurgical sealing devices with scissor-closing jaws is shown. For the conventional devices, the pressure decreases from the proximal end of the jaws to the distal tip, reaching a pressure of virtually zero within the last quarter of the jaw length. The hinged jaw of the new device enables much more even pressure distribution throughout the jaw length of 26,5 mm. Pressure data outside of the jaw footprint (dashed line) was removed for clarity.
