Abstract
A surgical access system includes a connector including an arm having first and second end portions, a coupling element having a body portion defining a cavity therein, and a gear assembly. The gear assembly includes a first gear disposed within the cavity of the coupling element and a second gear non-rotatably disposed at the first end portion of the arm. The first and second gears are meshingly engaged with each other such that rotation of the first gear results in rotation of the second gear which, in turn, causes the arm to pivot with respect to the coupling element.
Claims18
A surgical access system comprising:
- a beam;
- a first support operably coupled to the beam;
- and
- a first connector operably connected to the first support, the first connector including:
- an arm including a first end portion and a second end portion, wherein the second end portion of the arm includes a cavity having a receiving element disposed therein, the receiving element including an engaging portion movable between a locked state and an unlocked state;
- a coupling element including a body portion defining a cavity therein;
- and
- a gear assembly including a first gear disposed within the cavity of the coupling element and a second gear non-rotatably disposed at the first end portion of the arm, the first and second gears meshingly engaged with each other such that rotation of the first gear results in rotation of the second gear which, in turn, causes the arm to pivot with respect to the coupling element;
- and
- a first retractor blade including a planar portion, the planar portion including a protruding portion releasably engaged with the engaging portion of the receiving element.
A surgical access system comprising:
- a first support;
- a second support;
- a cross bar interconnecting the first and second supports;
- and
- a first connector operably connected to the cross bar, the first connector including:
- an arm including a first end portion and a second end portion, wherein the second end portion of the arm includes a cavity having a receiving element disposed therein, the receiving element including an engaging portion movable along a receiving axis;
- a coupling element including a body portion defining a cavity therein;
- and
- a gear assembly including a first gear disposed within the cavity of the coupling element and a second gear non-rotatably disposed at the first end portion of the arm, the first and second gears meshingly engaged with each other such that rotation of the first gear results in rotation of the second gear which, in turn, causes the arm to pivot with respect to the coupling element about a pivot axis that is parallel to the receiving axis.
