1. An apparatus comprising:
- a base hoop, sized and shaped to be disposed about a burr hole, the base hoop including an upper surface and a lower surface, the base hoop includes an access passage, the access passage extends between the upper surface and lower surface, the base hoop includes at least one hole sized and shaped for receiving a fastener therethrough to secure the base hoop; and
a lid coupled to the base hoop, the lid includes at least one slot, the slot extends through the lid and includes at least one socket, the socket is sized and shaped to retain at least one instrument, the slot being defined by a first surface and a second surface of the lid, the first and second surfaces being separated at a first fixed distance apart from each other, the at least one instrument insertable between the first and second surfaces to be guided toward the socket, the first and second surfaces remaining separated at the first fixed distance apart from each other when the at least one instrument is retained in the socket, the first and second surfaces remaining separated at the first fixed distance apart from each other when the at least one instrument is absent from the socket.

17. An apparatus comprising:
-
a base hoop, sized and shaped to be disposed about a burr hole, the base hoop including an upper surface and a lower surface, the base hoop including an access passage having an axis, the access passage extending between the upper surface and lower surface of the base hoop, the base hoop including at least one hole receiving a fastener therethrough to secure the base hoop, the upper surface of the base hoop including a lateral groove that extends from an edge of the base hoop to the access passage in a direction substantially perpendicular to the axis; and a lid that covers a portion of the access passage, the lid being rotatably coupled to the base hoop to rotate about the axis of the access passage relative to the base hoop, the lid including at least one fixed slot extending through the lid to partially uncover the access passage, the lid further including a fixed socket in communication with the slot, the lid further including a resilient lip between the slot and the socket, the resilient lip resiliently deflecting to allow passage of an instrument between the slot and the socket and to retain the instrument within the socket. - View Dependent Claims (18, 19)

20. An apparatus comprising:
-
a base hoop, sized and shaped to be disposed about a burr hole, the base hoop including an upper surface and a lower surface, the base hoop including an access passage having an axis, the access passage extending between the upper surface and lower surface of the base hoop, the base hoop including a first hole and a second hole, the first and second holes each receiving a fastener therethrough to secure the base hoop, the first and second holes being disposed substantially symmetrically about the access passage, the upper surface of the base hoop including a lateral groove that extends from an edge of the base hoop to the access passage in a direction substantially perpendicular to the axis; and a lid that covers a portion of the access passage, the lid being rotatably coupled to the base hoop to rotate about the axis of the access passage relative to the base hoop, the lid including at least one fixed slot extending through the lid to partially uncover the access passage, the slot extending from an edge of the lid and tapering inward toward the axis, the lid further including a fixed socket that is substantially centered on the axis and that is in communication with the slot, the lid further including a plurality of resilient lips disposed between the slot and the socket, the socket receiving an instrument, the plurality of lips resiliently deflecting to allow passage of the instrument between the socket and the slot and to retain the instrument within the socket, the lid including a lateral groove that extends from the socket to the edge of the lid, the lateral groove of the lid being alignable with the lateral groove of the base loop, and the lateral groove of the lid and the lateral groove of the base loop retaining the instrument therein.
