Surgical access instrument
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.
1. A system for illuminating a surgical working portal, comprising:
an access instrument including:
a tubular body having a first end, a tubular body length, a lower monolithic portion, an extension extending from a transition portion of an upper portion of the tubular body, a first slot defined by a rim and having a first slot length running along the length of the tubular 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 tubular body, the first slot and the second slot extending entirely through the tubular body and the first slot length and the second slot length being less than the tubular body length; and
a lighting device including an elongated arm, a head including a light source, and a leg connecting the elongated arm with the head.
2. The system of claim 1 , wherein the leg includes two legs defining a slot therebetween, the slot configured to receive an instrument.
3. The system of claim 2 , wherein the head of the lighting device is extendable within the tubular body of the access instrument.
4. The system of claim 3 , wherein an external surface of the head is configured to contact an internal surface of the tubular body.
5. The system of claim 3 , wherein the slot of the lighting device aligns with at least one of the first and second slots of the tubular body.
6. The system of claim 5 , wherein the instrument is extendable through the slot of the lighting device and at least one of the first and second slots of the tubular body.
7. The system of claim 6 , wherein the instrument includes two instruments, a first instrument extendable through the slot of the lighting device and the first slot of the tubular body and a second instrument extendable through the slot of the lighting device and the second slot of the tubular body.
8. The system of claim 1 , wherein the elongated arm, the head, and the leg are monolithic.
9. The system of claim 1 , wherein the head is semicircular and defines two diametrically opposed edges.
10. The system of claim 9 , wherein the light source includes two light sources, each light source positioned on one of the diametrically opposed edges.
11. The system of claim 10 , wherein the light source is one of a light-emitting diode, fluorescent bulb, and incandescent bulb.
12. A system for creating a surgical working portal, comprising:
an access instrument including:
a tubular body having a first end, a tubular body length, a lower monolithic portion, an extension extending from a transition portion of an upper portion of the tubular body, a first slot defined by a rim and having a first slot length running along the length of the tubular 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 tubular body, the first slot length and the second slot length extending entirely through the tubular body and being less than the tubular body length; and
a shim including a shim body and a tab, the shim insertable in the tubular body of the access instrument in an inserted configuration.
13. The system of claim 12 , wherein the shim body is substantially cylindrical and defines an opening at a top end and a bottom end.
14. The system of claim 13 , wherein an outer diameter of the shim body is smaller than an inner diameter of the tubular body.
15. The system of claim 12 , wherein the tab extends from a top end of the shim body in a plane perpendicular to a longitudinal axis of the shim body.
16. The system of claim 15 , wherein the tab contacts the rim of the tubular body in the inserted configuration.
17. The system of claim 12 , wherein the shim body has a length longer than the first slot length and the second slot length.
18. The system of claim 12 , wherein the shim is rotatable within the tubular body.
19. The system of claim 12 , wherein an instrument is insertable through the shim in the inserted configuration.
20. A kit for illuminating a surgical working portal, comprising:
an access instrument including:
a tubular body having a first end, a tubular body length, a lower monolithic portion, an extension extending from a transition portion of an upper portion of the tubular body, a first slot defined by a rim and having a first slot length running along the length of the tubular 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 tubular body, the first slot length and the second slot length extending entirely through the tubular body and being less than the tubular body length; and
a shim including a shim body and a tab, the shim insertable in the tubular body of the access instrument in an inserted configuration; and
a lighting device including an elongated arm, a head including a light source, and a leg connecting the elongated arm with the head, the head insertable in the tubular body of the access instrument in the inserted configuration.
