  • Reciprocating rotary arthroscopic surgical instrument
    Patent number: 7226459
    Abstract: A surgical instrument includes a cutting member with an implement for cutting tissue, and a drive coupled to the cutting member to simultaneously rotate and translate the cutting member in response to a force applied to the drive. A method of cutting tissue includes positioning an outer member such that tissue is located within the outer member, engaging the tissue with an inner member, and simultaneously rotating and translating the inner member to cut the tissue. A tangential cutting force is applied to the tissue with the inner member to mechanically cut the tissue. The inner member is mechanically driven to undergo simultaneous rotation and translation.

  • Reciprocating rotary arthroscopic surgical instrument
    Publication number: 20040092980
    Abstract: A surgical instrument includes a cutting member with an implement for cutting tissue, and a drive coupled to the cutting member. The drive may include a drive member having a helical groove and being attached to the cutting member. Furthermore, the drive may include an inner drive hub coupled to the drive member such that the drive member rotates with the inner drive hub while being free to translate relative to the inner drive hub. The drive simultaneously rotates and translates the cutting member in response to a force applied to the drive.
