Optical trocar assembly
A cannula assembly configured to receive a surgical instrument therethrough includes an elongated body portion, a housing coupled to a proximal end portion of the elongated body portion, and an annular-shaped light member. The housing defines a longitudinally-extending channel therethrough dimensioned for passage of the surgical instrument. The light member is disposed within the housing and about the channel.
1. A cannula assembly configured to receive a surgical instrument therethrough, the cannula assembly comprising:
an elongated body portion;
a cover coupled to a proximal end portion of the elongated body portion;
a housing configured to be detachably coupled to the cover, the housing defining a longitudinally-extending channel therethrough dimensioned for passage of a surgical instrument;
a light pipe having a proximal end portion received within and attached to the housing, the light pipe extending distally from the housing and configured for receipt in the elongated body portion; and
an annular-shaped light member attached to the housing and disposed about the channel.
2. The cannula assembly according to claim 1 , wherein the housing has an upper surface defining an aperture in communication with the channel, the light member being disposed adjacent the aperture.
3. The cannula assembly according to claim 2 , wherein the upper surface of the housing is clear to provide visual access of the light member.
4. The cannula assembly according to claim 1 , wherein the housing is detachable from the cover to allow for the selective coupling of an obturator assembly to the elongate body portion.
5. The cannula assembly according to claim 1 , wherein the light pipe is configured to transfer light emitted from the light member to a distal end portion of the elongated body portion.
6. The cannula assembly according to claim 5 , wherein the proximal end portion of the light pipe is disposed adjacent the light member, and the light pipe has a distal end portion disposed adjacent the distal end portion of the elongated body portion.
7. The cannula assembly according to claim 1 , further comprising a battery electrically coupled to the light member for powering the light member.
8. The cannula assembly according to claim 1 , wherein the light member includes a plurality of light-emitting-diodes (LEDs).
9. The cannula assembly according to claim 1 , wherein the light member is disposed within the housing.
10. The cannula assembly according to claim 1 , wherein the proximal end portion of the light pipe has the light member received therein.
11. The cannula assembly according to claim 1 , wherein the light pipe has a plurality of markings along a length thereof configured to emit a greater intensity of light than the remainder of the light pipe.
