1. Surgical apparatus, comprising:
a trocar having a tubular member with a tubular member distal end and a tubular member proximal end, configured for insertion into a body cavity, and defining a passageway configured to allow passage of a surgical tool comprising a tool proximal end and a tool distal end, from the tubular member proximal end to a position in which the tool distal end projects beyond the tubular member distal end; and an indicator mounted on the trocar configured to apply indications onto surgical tools in the passageway, such that the indications can be identified by an endoscope in the body cavity while the tool distal end projects beyond the tubular member distal end.
