Abstract
A surgical accessory includes a shaft extending along a longitudinal axis from a distal head to a proximal engagement surface. At least one rib or land protrudes from the shaft along an intermediate portion between the distal head and the proximal engagement portion. The rib or land may form at least one flute at a helix angle along the intermediate portion. A detent is connected along the proximal engagement surface and engages a complimentary retention feature of a receiving socket in a coupled arrangement forming a coupling interface.
Claims20
A surgical accessory for a surgical tool comprising:
- a shaft extending along a longitudinal axis from a distal head to a proximal engagement interface;
- at least one rib protruding from the shaft along an intermediate portion between the distal head and the proximal engagement portion, the at least one rib forming at least one flute at a helix angle along the intermediate portion;
- and
- a detent in connection with the proximal engagement interface, wherein the detent engages a complementary retention feature of a receiving socket.
A coupling interface for a surgical tool comprising:
- a socket adapter comprising:
- an adapter body having a receiving opening formed by an interior wall;
- at least one protrusion extending into the receiving opening from the interior wall;
- and
- a rotary accessory comprising:
- a shaft extending along a longitudinal axis from a distal head to a proximal engagement interface;
- at least one rib protruding from the shaft and spiraling along an intermediate portion between the distal head and the proximal engagement portion, the at least one rib forming at least one flute at a helix angle along the intermediate portion;
- and
- wherein the shaft is received within the receiving opening and the protrusion rotationally engages the at least one flute along the helix angle engaging the surgical tool to the socket adapter.
A socket adapter for a rotary accessory comprising:
- an adapter body extending from a proximal end portion to a distal end portion, the distal end portion comprising a receiving opening formed by an interior wall and a cannula extending through the body from the proximal end portion to the distal end portion;
- at least one protrusion extending into the receiving opening from the interior wall at the distal end portion;
- and
- a retaining aperture formed in the interior wall at an intermediate portion between the proximal end portion and the distal end portion, wherein the retaining aperture is configured to receive a detent of an engagement portion of the rotary accessory.
