Abstract
A device includes an outer member extending along a longitudinal axis between a first end and a second end. The first end includes an opening. The outer member includes an inner surface defining a first passageway that is in communication with the opening. An inner member is movably disposed in the first passageway. The inner member includes an inner surface defining a second passageway. The inner member further includes a first end including a cutting tip. The inner member is movable between a first orientation in which the cutting tip is disposed within the first passageway and the inner member has a linear configuration and a second orientation in which the cutting tip extends through the opening and the inner member has an arcuate configuration. Methods of use are provided.
Claims20
A device for performing a surgical procedure comprising:
- an outer member extending along a longitudinal axis between a first end and a second end, the first end including an opening, the outer member including an inner surface defining a first passageway that is in communication with the opening;
- and
- an inner member movably disposed in the first passageway, the inner member including an inner surface defining a second passageway, the inner member further including a first end including a cutting tip,
- wherein the inner member is movable between a first orientation in which the cutting tip is disposed within the first passageway and the inner member has a linear configuration and a second orientation in which the cutting tip extends through the opening and the inner member has an arcuate configuration.
A method for correction of a bone injury comprising:
- providing a device comprising:
- an outer member extending along a longitudinal axis between a first end and a second end, the first end including an opening, the outer member including an inner surface defining a first passageway that is in communication with the opening, and
- a stylet removably disposed in the passageway, the stylet including a blunt tip that extends through the opening;
- inserting the stylet through an incision and translating the stylet into the anatomy of a patient such that the stylet creates an access path to a selected portion of the patient's anatomy;
- removing the stylet from the first passageway;
- inserting an inner member into the first passageway, the inner member including an inner surface defining a second passageway, the inner member further including a first end including a cutting tip;
- translating the inner member between a first orientation in which the cutting tip is disposed within the first passageway and the inner member has a linear configuration and a second orientation in which the cutting tip extends through the opening and the inner member has an arcuate configuration;
- and
- applying mechanical force to the inner member such that the cutting tip cuts through the selected portion of the patient's anatomy.
A surgical system comprising:
- an outer member extending along a longitudinal axis between a first end and a second end, the first end including a circular opening extending parallel to the longitudinal axis, the outer member including an inner surface defining a first passageway having a cylindrical configuration that is in communication with the opening, the first passageway extending parallel to the longitudinal axis and having a uniform diameter;
- a stylet removably disposed in the passageway, the stylet including a blunt tip that extends through the opening configured to create an access path to a selected portion of a patient's anatomy;
- and
- an inner member comprising a super elastic metal movably disposed in the first passageway after the stylet is removed from the first passageway, the inner member including an inner surface defining a second passageway, the inner member further including a first end including a cutting tip having an aperture including a first portion extending parallel to the longitudinal axis and a second portion extending perpendicular to the longitudinal axis, the aperture defining a scoop portion of the cutting tip, the inner member including at least one electrode positioned adjacent the aperture configured to emit radio frequency (RF) energy to cut and/or destroy tissue and/or nerves, a second end of the inner member being coupled to a suction source to provide suction through the aperture and into the second passageway, the second end of the inner member also being coupled to an irrigation source to deliver irrigation fluid through the second passageway and the aperture;
- wherein the inner member is movable between a first orientation in which the cutting tip is disposed within the first passageway and the inner member has a linear configuration and a second orientation in which the cutting tip extends through the opening and the inner member has an arcuate configuration.
