A medical instrument for providing access to the interior of the body comprises a shaft having an elongated base body and a handle. The base body extends between a distal end and a proximal end of the shaft. The handle is coupled to the base body of the shaft at the proximal end. The shaft defines at least a first channel and a second channel that extend through the shaft. The first channel provides a passage for surgical instruments through the shaft. The second channel is adapted to accommodate an observation optics. The second channel is adjacent to at least one secondary channel that is connected to the second channel.
