    摘要： A cannula insertion system configured to divide a cannula insertion process into a two-step process. The first step advances a needle portion a first distance and the second step advances the needle portion a second distance. The first step and the second step may be at different angles. At least one of the angles may be less than 90°. At least one of the steps may be mechanically assisted.

    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.

    摘要： A cannula device for an ophthalmic surgical procedure includes a cannula configured to be inserted through a sclera of an eye and a disk structure configured to apply a force on the sclera to sustain a position of the cannula. A cannula insertion sustaining system for an ophthalmic procedure includes a cannula tube configured to be inserted through a sclera of an eye, an upper tube portion, and a connector tube coupled to the upper tube portion and to the cannula tube. The connector tube is configured to reduce an effective pulling vector force asserted on the cannula tube. A method of sustaining a position of a cannula in a sclera includes inserting the cannula through the sclera and engaging a support structure with the sclera to apply a force on the sclera.
