Abstract
An end effector includes a drive system to rotatably drive a removeable cutting accessory. The cutting accessory defines a bore. The drive system includes a drive member that defines a lumen. A cartridge is provided to deliver liquid from a liquid source, through the lumen of the drive member, through the bore of the cutting accessory, and to a surgical site.
Claims12
An end effector comprising:
- a housing;
- a nose tube coupled to said housing;
- a cutting accessory defining a bore;
- a drive system including an actuator, a rotational drive member having a distal end and an opposing proximal end, said rotational drive member disposed within said nose tube and configured to be rotated relative to said nose tube by said actuator, and a drive connector coupled to said distal end of said rotational drive member, said drive connector configured to releasably engage said cutting accessory and to rotate the cutting accessory, said rotational drive member defining a lumen for receiving liquid from a liquid source, wherein said lumen is configured to be in communication with said bore of said cutting accessory so that said bore is capable of delivering the liquid from said lumen to a surgical site;
- a first seal configured to seal between said drive system and said cutting accessory;
- and
- a cartridge releasably coupled to said proximal end of said rotational drive member to deliver the liquid from the liquid source to said lumen of said rotational drive member, said cartridge including a second seal configured to seal against said rotational drive member during rotation of said rotational drive member relative to said cartridge, wherein said housing defines a cavity that releasably receives said cartridge.

An end effector for actuating a cutting accessory, said end effector comprising:
- a housing;
- a nose tube coupled to said housing;
- a drive system including an actuator, a rotational drive member disposed within said nose tube and configured to be rotated relative to said nose tube by said actuator, and a drive connector coupled to said rotational drive member, said drive connector configured to releasably engage the cutting accessory to rotate the cutting accessory, said rotational drive member defining a lumen for receiving liquid from a liquid source, wherein said lumen is configured to be in communication with a bore of the cutting accessory so that the bore is capable of delivering the liquid from said lumen to a surgical site;
- a first seal configured to seal between said drive system and the cutting accessory;
- and
- a cartridge releasably coupled to a proximal end of said rotational drive member to deliver the liquid from the liquid source to said lumen of said rotational drive member, said cartridge including a second seal configured to seal against said rotational drive member during rotation of said rotational drive member relative to said cartridge, wherein said housing defines a cavity that releasably receives said cartridge.
