Abstract
Various embodiments of a dural elevating and cutting apparatus and methods of use are disclosed herein.
Claims16
An apparatus, comprising:
- a scalpel housing defining a handle and a shield storage slot, the scalpel housing terminating in a head portion, wherein a distal end of the head portion defines a tip configured for engagement with a blade;
- a shield defining an elevator and a blade shield in association with the head portion of the scalpel housing;
- and
- a rotator defined by the shield in engagement with a rotator receptacle defined by the head portion of the scalpel housing;
- wherein the shield is operable for rotation in a clockwise or counterclockwise direction between a recessed position in engagement with the shield storage slot of the scalpel housing and an engaged position such that the blade shield engages with the head portion of the scalpel housing and the elevator is positioned in distal relation to the tip;
- wherein the rotator receptacle comprises:
- a horizontal slot configured to receive the rotator of the shield
- wherein the rotator receptacle comprises:
- a post formed within the horizontal slot.

6 more elements
A shield for a dura elevating and cutting apparatus, comprising:
- a stem having a proximal end and a distal end;
- a rotator defined at the proximal end of the stem and configured for engagement with a rotator receptacle of a scalpel housing of the dura elevating and cutting apparatus;
- an elevator defined at the distal end of the stem;
- and
- a blade shield defined along a midsection of the stem and comprising a tip lock;
- wherein the stem is configured for engagement with a shield storage slot of the scalpel housing in a recessed position and the blade shield is configured for engagement with a head portion of the scalpel housing in an engaged position;
- and
- wherein the rotator is rotatable in a clockwise or counterclockwise direction between the recessed position and the engaged position.
5 more elements
A method, comprising:
- inserting a rotator of a shield into a rotator receptacle of a scalpel housing, wherein the rotator comprises a longitudinal portion in communication with a circular portion and a latitudinal portion oriented in perpendicular relation to the longitudinal portion and in communication with the circular portion such that a post defined within the rotator receptacle slides through the longitudinal portion and is disposed within the circular portion;
- rotating the rotator in a clockwise or counterclockwise direction such that a direction of elongation of the shield is aligned with a direction of elongation of the scalpel housing;
- and
- driving the rotator in a lateral direction relative to the scalpel housing such that the post of the rotator receptacle engages within the latitudinal portion.
