CONTACT DETECTION TUBES, METHODS AND SYSTEMS FOR MEDICAL PROCEDURES |
摘要 |
A contact detection method (70) involves a navigation of a contact detection tube (20′) within an open space of an anatomical region (50) of a body. The contact detection tube includes a tubular wall (21) having an interior surface (23) defining a working channel (24), and an electrode (30) integrated in the tubular wall (21). The electrode (30) electrically connects the contact detection tube (20′) to an electrically conductive object (41, 52) (e.g., biological tissue or a medical instrument/tool) in physical contact with an exterior surface (22) of the tubular wall (21) and electrically isolates the working channel (24) from any electrical connection of the tube (20′) to the object (41, 52). The method (70) further involves a determination of a contact status of the contact detection tube (20′) between an open state (i.e., no physical contact) and a closed state (i.e., physical contact). |
