ADJUSTABLE CANNULA SYSTEMS AND DEVICES |
摘要 |
Various adjustable cannula systems are provided. The systems can include an adjustable cannula capable of expansion and/or contraction having an elongate body with a distal end and a proximal end. The adjustable cannula can be coupled to an upper housing and a lower housing such that rotation of the upper housing results in expansion or contraction of the adjustable cannula. The adjustable cannula can also have a proximal end having a lumen larger than a distal end lumen. A plurality of flanges can be formed in the elongate body by a plurality of slits that span a majority of a length of the cannula, including along or proximate to its proximal end and distal end. |
