Abstract
An endoscopic surgical device comprising a slotted clear cannula, a blade and a housing, wherein the cannula is attached to the housing, and wherein the blade is enclosed in the housing and is slidable into the cannula is disclosed. The blade is enclosed within the housing and cannula, and has a horizontally-oriented pushing component and a vertically-oriented cutting component that protrudes through the slot of the cannula. A method for a performing an operative procedure on a target tissue in a subject using the endoscopic surgical device is also described.

An endoscopic surgical device, comprising:
- (a) a housing having a proximate end and a distal end;
- (b) a slotted clear cannula attached to said distal end of said housing, said slotted clear cannula comprises a cannula body having a proximate end and a distal end, and a slot extending from said proximate end of said cannula to the proximity of said distal end of said cannula;
- (c) a revolver assembly located within said housing, comprising:
- a slide lock having a proximate end, a distal end and two notches at said distal end;
- a scraper;
- a blade assembly;
- and
- a circular revolver body comprising a selector switch;
- wherein said scraper and said blade reside at said two notches of said slide lock in a pre-deployment position and wherein said selector switch allows selection of said scraper or said blade for deployment;
- and
- (d) a tube assembly having a proximate end and a distal end, said distal end of said tube assembly is located within said housing and extends through said revolver, said tube assembly is capable of entering said slotted clear cannula from said proximate end of said clear cannula;
- the device further comprising a rotary clip that prevents said scraper and said blade from sliding when in undeployed positions, wherein said rotary clip comprises a tab that engages with an inside surface of said housing and an opening that allows deployment of said scraper or said blade.
