Pdf Summary

The Laparoscopic Tactile Imager (LTI) is a system that aims to provide tactile feedback during laparoscopic surgeries. In traditional laparoscopy, tactile sensation is impaired, and in robotic laparoscopy, it is completely lacking. The LTI system includes a detachable laparoscopic probe, a calibration chamber, signal acquisition electronics, an HD laparoscope, and a computer with touch screen display.<br /><br />In a pilot clinical study, five subjects underwent urogynecological surgery with the LTI system. The system was used prior to tissue dissection to assess surgically relevant areas. The probe was used to visualize pressure patterns from palpated tissue, allowing better differentiation of tissue properties within the pelvis. The areas of interest included the pelvic sidewall, sacral promontory, and bladder reflection.<br /><br />All five cases were successfully completed, and the LTI probe was found to be useful in identifying correct dissection planes, particularly in cases with scar tissue or distorted anatomy. It also helped in optimizing the placement of sutures. Additionally, abnormalities in the tissue, such as an endometriosis implant and a retroperitoneal fibroid tumor, were palpated using the LTI probe.<br /><br />The LTI system has the potential to assist surgeons in clarifying anatomical structures and making clinical decisions during urogynecological surgery. It allows for real-time visualization of pressure patterns and calculation of tissue elasticity maps. The system could be valuable in cases where additional tactile feedback is needed, such as surgeries involving scar tissue or distorted anatomy.<br /><br />This pilot clinical study was supported by NIH/NICHD grant and was presented at the AUGS 2017 conference in Providence, RI.
