Abstract

Disclosed herein are sealing devices configured for improving sealing functionality with an engaged extension member of an apparatus. More specifically, disclosed herein are trocar sealing devices configured for improving insufflation gas containment in relation to trocars (and/or other related type of devices) that are used for enabling a surgical instrument such, for example, a laparoscope, to gain access to an abdominal cavity (or other body cavity). By providing for such improved insufflation gas containment, sealing devices as disclosed herein are particularly advantageous, desirable and useful in view of long-standing reasons for limiting insufflation gas leakage and in view of newly recognized reasons stemming from outbreak of COVID-19 disease for limiting insufflation gas leakage.
