Abstract
Surgical access systems and obturators for or used in surgical access systems are provided. The obturator is configured to operate or accommodate the use of at least two different sized trocars. The outer diameter of the adaptable obturator when inserted into a trocar compresses from an initial condition to a compressed condition to match the inner diameter of the trocar.
Claims23
An obturator insertable into at least two different sized trocars, the obturator comprising:
- an elongate shaft having a proximal end and a distal end;
- a handle at the proximal end of the elongate shaft;
- a tip at the distal end of the elongate shaft;
- and
- at least one compressible portion disposed between the handle and the tip and not extending past the tip, the at least one compressible portion having an initial state delimiting a first diameter and the at least one compressible portion movable to a compressed state delimiting a second diameter smaller than the first diameter;
- wherein the at least one compressible portion is at least one compressible rib, the at least one compressible rib extends up to a gap portion separating a proximal end of the at least one compressible rib with a prong.

A trocar system comprising:
- a first trocar having a seal assembly and a cannula with an inner diameter and a length;
- an obturator insertable into the first trocar, the obturator comprising:
- an elongate shaft having a proximal end and a distal end;
- a handle at the proximal end of the elongate shaft;
- a tip at the distal end of the elongate shaft, the tip being as rigid as the elongate shaft and the tip and the elongate shaft being insertable through the seal assembly of the first trocar;
- and
- a compressible portion disposed between the handle and the tip and not extending past the tip, the at least one compressible portion delimiting a first diameter greater than the inner diameter of the cannula and compressible to delimit a second diameter smaller than the inner diameter of the cannula.
