Abstract
An obturator for use in surgical procedures, particularly minimally invasive procedures. The obturator has an elongated member having a distal piercing tip. The obturator also has a longitudinal groove for containing a surgical instrument for insertion into a body space.
Claims25
An obturator, comprising
- a solid rod having a distal end, a proximal end, a longitudinal axis and an outer surface;
- a groove extending partially into the rod through the outer surface, said groove substantially parallel to the longitudinal axis, said groove having a proximal end, a distal end proximal to the distal end of the rod, a closed bottom, opposed sides, a width between the sides and an open top having a width, wherein the width of the opening of the top is greater than or equal to the width between the sides;
- and,
- a piercing point extending distally from the distal end of the rod,
- wherein an elongated instrument contained within the groove is displaceable radially outward from the groove.

A method of performing a surgical procedure, comprising:
- providing an obturator comprising:
- a solid rod having a distal end, a proximal end, a longitudinal axis and an outer surface;
- a groove extending partially into the rod through the outer surface, said groove substantially parallel to the longitudinal axis, said groove having a proximal end, a distal end proximal to the distal end of the rod, a closed bottom, opposed sides, a width between the sides and an open top having a width wherein the width of the opening of the top is greater than or equal to the width between the sides;
- and,
- a piercing point extending distally from the distal end of the rod;
- inserting the distal end of the obturator through a body wall and into a body space;
- introducing an elongated surgical instrument into the body space by sliding the instrument through the groove in the obturator into the body space;
- and,
- displacing the instrument radially outward from the groove into the body space.

- and,
- a piercing point extending distally from the distal end of the rod;
- providing an elongated surgical instrument having a distal end;
- mounting the distal end of the surgical instrument in the groove of the obturator;
- simultaneously inserting the distal end of the obturator and the distal end of the surgical instrument contained within the groove through a body wall and into a body space;
- and,
- displacing the instrument radially outward from the groove into the body space.
