摘要： A minimally invasive retractor and dissector (10) for internal surgical use on a patient has a tubular support (11) for passing into the body; the tubular support (11) has a passage (16) for access along an axis "A" thereof during operative procedures on the patient's internal tissue. A proximal end (12) on the tubular support (11) is located outside the patient in position to be accessed by the surgeon when a distal end (13) is inside. One or more jointed articulated members (15) are movably positioned and capable of holding and pulling tissue disposed beyond the distal end (13) and each member has a distal tip (17) to hold tissue. An instrument capable of moving independent of any member functions cooperatively on the tissue and passes through the passage (16) from the proximal end (12) to beyond the distal end (13) as the members position the tissue. The instrument is a surgical tool and the tissue is maneuvered by the members within the body into a position relative to the tool. A control (19) at the proximal end (12) manipulates the members relative to the axis "A" permitting holding and pulling tissue disposed beyond the distal end (13); the control (19) is capable of moving the instrument independent of the members for operating on the held and maneuvered tissue. A grip (34) manipulates the members and positions the instrument. A method for using the minimally invasive retractor and dissector (10) has the steps of making an opening for a tubular support (11) to pass into the body, leaving the proximal end (12) on the tubular support (11) outside the body, positioning the distal end (13) thereof inside, and moving members carried on the tubular support (11). Holding and pulling tissue disposed beyond the distal end (13) and using the passage (16) for access along the axis thereof for operating on internal tissue are added steps. Another step is moving an instrument in the passage (16) independent of the members.
