Illumination sleeve
A tissue removal system may include a tissue removal device including a handpiece and an upper housing, and configured with an outer cannula having an outer cannula opening for severing tissue, an inner cannula disposed in the outer cannula and reciprocal within the outer cannula, an illumination device having a sleeve arranged at least partially on the outer cannula, and a fiber optic channel defining an opening and arranged offset from the sleeve, and a light source arranged within the channel and configured to supply light from the opening to a surgical site.
1. A tissue removal system, comprising:
a tissue removal device including a handpiece and an upper housing, and configured with an outer cannula and an inner cannula disposed in the outer cannula,
an illumination device including a hub configured to selectively attach to the tissue removal device at the upper housing and having a sleeve arranged at least partially on the outer cannula, the hub defined by a semi-cylindrical body that partially surrounds a distal end of the upper housing, the semi-cylindrical body having a cut-out portion that is defined between first and second edges,
a snap feature formed within the semi-cylindrical body,
an optic channel defining an opening and arranged offset from the sleeve, and
a light source arranged within the channel and configured to supply light from the opening to a surgical site.
2. The system of claim 1 , wherein the light source is a fiber optic cable.
3. The system of claim 2 , wherein the fiber optic cable extends outwardly from the sleeve opening.
4. The system of claim 1 , wherein the semi-cylindrical body is configured to cover a portion of the upper housing.
5. The system of claim 4 , wherein the hub is rotatable with respect to the upper housing.
6. The system of claim 1 , wherein the sleeve opening is proximal to a distal end of the outer cannula opening.
7. An illumination device for tissue removal system, comprising:
a sleeve arranged at least partially on an outer cannula of a tissue removal system, the sleeve including a light source to provide light to a surgical site at a distal sleeve opening;
a hub including a semi-cylindrical body configured to selectively attach around a distal end of an upper housing of the tissue removal system and maintain the sleeve therein, the semi-cylindrical body being rotatable with respect to the upper housing; and
wherein the semi-cylindrical body defines at least one snap feature configured to engage a portion of the upper housing, wherein the snap feature is defined by a slit formed in the semi-cylindrical body, the slit extending from a proximal end of the semi-cylindrical body toward a distal end of the semi-cylindrical body along a portion of a length of the cylindrical body.
8. The device of claim 7 , wherein the semi-cylindrical body is rotatable between a first position where a first edge of the semi-cylindrical body abuts a handpiece and a second position where a second opposite edge of the semi-cylindrical body abuts the handpiece.
9. The device of claim 7 , wherein the semi-cylindrical body is rotatable approximately 120 degrees.
10. The device of claim 7 , wherein the snap feature engages the upper housing and is configured to fix the hub to the upper housing to prevent movement of the hub in a lateral direction with respect to the upper housing.
11. The device of claim 10 , wherein the snap feature is configured to engage a ring arranged on the upper housing, wherein the hub is configured to rotate about the ring.
12. An optic attachment assembly for tissue removal system, comprising:
a hub defined by a semi-cylindrical body, wherein the hub defines at least one snap feature configured to engage a portion of a housing of a tissue removal system, wherein the snap feature is defined by a slit formed in the semi-cylindrical body, the slit extending from a proximal end of the semi-cylindrical body toward a distal end of the semi-cylindrical body along a portion of a length of the cylindrical body;
a sleeve connected to the huh, the sleeve being sized to at least partially be disposed about an outer cannula of a tissue removal system, the sleeve including a fiber optic cable; and
a housing including a light source configured to provide light to the fiber optic cable, the housing including a cage surrounding the light source to prevent exposure to the light source, but the cage further having a plurality of openings, wherein the cage includes at least one clamp to selectively attach the housing to the tissue removal system.
13. The assembly of claim 12 , wherein the housing includes a heat sink arranged around the light source to dissipate heat generated by the light source.
14. The assembly of claim 13 , wherein the cage surrounds the heat sink and the plurality of openings in the cage to provide air exposure to the heat sink.
15. A tissue removal system, comprising:
a tissue removal device having a housing and configured with an outer cannula,
an illumination device including hub configured to selectively attach to the tissue removal device and having a sleeve arranged at least partially on the outer cannula, the hub including a semi-cylindrical body that partially surrounds a distal end of the housing,
a snap feature formed within the semi-cylindrical body, wherein the snap feature is defined by a slit formed in the semi-cylindrical body, the slit extending from a proximal end of the semi-cylindrical body toward a distal end of the semi-cylindrical body along a portion of a length of the cylindrical body, wherein the snap feature is pliable with respect to the semi-cylindrical body,
an optic channel defining an opening and arranged offset from the sleeve, and
a light source arranged within the channel and configured to supply light from the opening to a surgical site.
16. The system of claim 15 , wherein the semi-cylindrical body comprises a first edge and a second edge that define an exposed portion therebetween.
