a connector;
a surgical cavity insertion tube; and
a suction tip comprising an inner hollow shaft and an outer hollow shaft coaxial to each other, the inner hollow shaft and the outer hollow shaft being made of a rigid material, the inner hollow shaft having a first central opening at a distal end thereof, the inner hollow shaft comprising an intermediate flange abutting a respective end of the outer hollow shaft on one side thereof and abutting a respective end of the surgical cavity insertion tube at an opposite side thereof, the outer hollow shaft having an end wall at a distal end thereof, the end wall having a second central opening in axial alignment with the first central opening of the inner hollow shaft, the outer hollow shaft having one or more openings on a lateral wall thereof, the suction tip having a weight per unit length greater than four times a weight of a same length of the surgical cavity insertion tube,
wherein the surgical cavity insertion tube is connected at a proximal end thereof to the connector and at a distal end thereof to the suction tip, and
wherein a distance between the distal end of the inner hollow shaft and an apex of the end wall of the outer hollow shaft is not more than 30% of a distance between the distal end of the inner hollow shaft and a distal edge of the intermediate flange,
