1. An instrument port for introducing an instrument into a surgical site, the instrument port comprising:
a port body including:
an instrument channel extending through the port body, and
first and second fluid flush channels each separate from one another and spaced laterally apart from the instrument channel, each extending along a major portion of the port body and in fluidic communication with the instrument channel, wherein the first and second fluid flush channels each comprise:
a first portion that extends parallel to the instrument channel and spaced alongside and laterally apart from the instrument channel, and
a second portion that extends transverse to the instrument channel and connects to the instrument channel,
wherein outer boundaries of the first portions of each of the first and second fluid flush channels define entirely separate interior volumes (i) from one another and (ii) from an interior volume defined by an outer boundary of the instrument channel, and
wherein the first portions of each of the first and second fluid flush channels are arranged adjacent to opposite sides of the port body;
a bulb comprising a bulb channel extending through the bulb, the bulb channel aligned with the instrument channel, wherein the bulb channel and instrument channel are configured to receive the instrument;
a port connectable to a source of partial vacuum; and
a valve in fluid communication between the port and either or both of the first and second fluid flush channels or between the port and the instrument.
