1. An endoscope comprising:
a handle;
an insertion cord extending from the handle and configured to be inserted into a patient's body cavity; and
a working channel tube extending from the handle into the insertion cord;
the handle comprising a Y-connector having:
a first branch including a first opening, a curved portion, and a first channel, the first opening comprising a radial outer point, the curved portion comprising a radial inner wall surface opposite a radial outer wall surface and a contacting point on the radial inner wall surface, the first channel extending distally from the first opening;
a second branch including a second opening from which a second channel extends; and
a third branch including a third opening, a curved portion, and a third joined channel, the curved portion comprising a radial inner wall surface, a radial outer wall surface and a landing point on the radial outer wall surface,
wherein the first channel and the second channel are joined in the third joined channel and the third joined channel extends inside the third branch towards the third opening,
wherein the first channel and the third joined channel form together an instrument insertion channel of the Y-connector, the second channel and the third joined channel form together a suction channel of the Y-connector, and the working channel tube is directly or indirectly connected to the third joined channel,
wherein a first straight line extending from the radial outer point of the first opening to the landing point on the radial outer wall surface of the third branch contacts the contacting point on the radial inner wall surface of the first branch, and
wherein the first straight line and a straight line tangential to the landing point on the radial outer wall surface of the third branch form a landing angle of between 0 and 20 degrees.
