| 摘要 |
<p>The present invention provides systems and methods for reducing the incidence of post-surgical tissue adhesions due to surgical incisions or perforations by applying heat, coolant, and/or sealant to or around the edges of the injured tissues, particularly to those in the peritoneum. One aspect of the invention is RF energy delivery systems (200), and control methods thereof. The RF delivery system is typically arranged to be coupled to a conventional surgical tool such as a trocar (70), and may include a surgical sheet (400), with one or more electrodes (401) for delivering the RF energy to the injured tissue resulting from conventional incisions into the abdominal wall. The treatment dosage of RF heat to the injured tissue may be controlled by monitoring parameters such as treatment time, change in tissue temperature, change in tissue dimension, and change in tissue impedance.</p> |
