摘要：
Embodiments include a method of performing a medical procedure in a patient. The method includes inserting a first working instrument and a second working instrument through an opening in the patient, creating an incision in body tissue inside the patient using at least one of the first and second working instruments, and advancing the second working instrument through the incision to position the second working instrument at a work site inside the patient. The method also includes positioning the first working instrument at the work site without advancing the first working instrument through the incision and performing a procedure at the work site inside the patient using the first and second working instruments.
