A surgical device, comprising: a handpiece having a distal end portion a tubular member extending from the distal end portion, the tubular member having a lumen therethrough, the lumen comprising: a) a proximal lumen portion, wherein the proximal lumen portion is a cylinder, b) a distal lumen portion, wherein a distal opening of the distal lumen portion terminates at a distal interior edge, and wherein a diameter of the distal inner edge is less than a diameter of the proximal lumen portion, c) a first central lumen portion connecting to the distal lumen portion, and d) a second central lumen portion, the second central portion being located between the proximal lumen portion and the first central lumen portion, wherein the distal lumen portion diverges as the distal lumen portion extends away from the first central lumen portion in a distal direction and terminates at the distal opening that forms a distal end of the tubular member, and the second central lumen portion diverges as the second central lumen portion extends away from the first central lumen portion in a proximal direction and; wherein an end effector is configured to extend out of the distal end of the tubular member, the end effector having arms (110a, 110b) moveable between a first position and a second position, the arms (110a,110b) extending wider than the distal opening when in the first position, the tubular member gathering the arms (110a, 110b) of the end effector when the tubular member is advanced or the end effector is retracted, thereby forcing the arms (110a,110b) of the end effector towards each other; and wherein the tubular member has a wall with a substantially uniform thickness about the first central lumen portion. a handpiece having a distal end portion a tubular member extending from the distal end portion, the tubular member having a lumen therethrough, the lumen comprising: a) a proximal lumen portion, wherein the proximal lumen portion is a cylinder, b) a distal lumen portion, wherein a distal opening of the distal lumen portion terminates at a distal interior edge, and wherein a diameter of the distal inner edge is less than a diameter of the proximal lumen portion, c) a first central lumen portion connecting to the distal lumen portion, and d) a second central lumen portion, the second central portion being located between the proximal lumen portion and the first central lumen portion, a) a proximal lumen portion, wherein the proximal lumen portion is a cylinder, b) a distal lumen portion, wherein a distal opening of the distal lumen portion terminates at a distal interior edge, and wherein a diameter of the distal inner edge is less than a diameter of the proximal lumen portion, c) a first central lumen portion connecting to the distal lumen portion, and d) a second central lumen portion, the second central portion being located between the proximal lumen portion and the first central lumen portion, wherein the distal lumen portion diverges as the distal lumen portion extends away from the first central lumen portion in a distal direction and terminates at the distal opening that forms a distal end of the tubular member, and the second central lumen portion diverges as the second central lumen portion extends away from the first central lumen portion in a proximal direction and; wherein an end effector is configured to extend out of the distal end of the tubular member, the end effector having arms (110a, 110b) moveable between a first position and a second position, the arms (110a,110b) extending wider than the distal opening when in the first position, the tubular member gathering the arms (110a, 110b) of the end effector when the tubular member is advanced or the end effector is retracted, thereby forcing the arms (110a,110b) of the end effector towards each other; and wherein the tubular member has a wall with a substantially uniform thickness about the first central lumen portion.
