Compact endoscopic surgical blade assembly and method of use thereof

摘要

An endoscopic surgical device having 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. The device further has a device for locking a viewing device in place relative to other components of the device. A method for a performing an operative procedure on a target tissue in a subject using the endoscopic surgical device is also described.

主权项

1. An endoscopic surgical device, comprising:
(a) a housing having a proximate end and a distal end; (b) a slotted cannula attached to said distal end of said housing, said slotted cannula comprises a cannula body having a proximate end and a distal end, and a slot extending from said proximate end of said cannula body to the proximity of said distal end of said cannula body; (c) a revolver assembly located within said housing, comprising:
a slide lock;a scraper;a blade assembly comprising a blade mounted on a pusher base; anda circular revolver body comprising a selector switch; wherein said scraper and said blade assembly reside at said slide lock in a pre-deployment position and wherein said selector switch allows selection of said scraper or said blade assembly for deployment; (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 distal end of the tube assembly is capable of entering said slotted cannula from said proximate end of said cannula body, wherein the pusher base comprises a notch that engages with a tool selector near the distal end of the tube assembly and a bottom surface curved to match the curvature of the tube assembly; and (e) a scope lock assembly for holding a viewing device in a stationary position relative to the tube assembly.
