Abstract
In one embodiment, an access instrument for creating a surgical working portal includes a body having a first end and a body length, a first slot having a first slot length running along the length of the body from the first end, and a second slot having a second slot length running along the length of the body from the first end, wherein the first slot length and the second slot length are less than the body length.
Claims20
An access instrument for creating a surgical working portal, comprising:
- a body having an upper portion, a lower monolithic portion, a first end, and a body length;
- an extension extending from a transition portion of the upper portion of the body;
- a first slot defined by a rim and having a first slot length running along the length of the body from the first end;
- and
- a second slot defined by the transition portion and having a second slot length running along the length of the body from the first end and in line with the extension, wherein the first slot length and the second slot length are less than the body length and the first and second slots extend entirely through the body.
A method of using an access instrument, comprising:
- inserting a first instrument within a passageway running through a port, and a body having a body length, an upper portion, a lower monolithic portion, and a first end;
- inserting a second instrument within the passageway;
- maneuvering the first instrument through a first slot defined by a rim and formed entirely through the body and having a first slot length running along the length of the body from the first end;
- and
- maneuvering the second instrument through a second slot defined by a transition portion and formed entirely through the body and having a second slot length running along the length of the body from the first end, wherein each of the first slot length and the second slot length is less than the body length and the first and second slots being opposite each other, the transition portion extending from the upper portion.
An access instrument comprising:
- an extension having a rim, the rim defining a first opening aligned with a central axis defined by the extension, and a second opening circumferentially opposite the first opening;
- a body having an upper portion, a lower monolithic portion, a body length, a first slot defined by the rim and having a first slot length from the rim and aligned with the first opening, and a second slot defined by a transition portion extending from the upper portion and having a second slot length from the rim and aligned with the second opening, the first slot length and the second slot length being less than the body length, the first and second slots extending entirely through the body.
