Abstract
A tool guide for guiding an end effector of a robotically controlled surgical instrument from a position outside a patient body to a position in close proximity to an internal surgical site within the patient body is provided. The tool guide typically comprises a body, a seat formation on the body, the seat formation being arranged to seat in an aperture leading into the patient body so as to mount the tool guide on the patient body, and a sheath formation on the body. The sheath formation typically defines a longitudinally extending internal passage, an inlet leading into the passage and an outlet leading from the passage.
