摘要:
A support apparatus for supporting a trocar while the trocar extends through a body wall of a patient includes an inflatable collar and a slidable abutment collar commonly connected for engagement onto the trocar following which the slide collar is released to slide along the trocar. The inflatable collar is inflated to a set size by a manually operable pump on the slidable collar operated by squeezing finger abutments together up to a latch so that threaded portion expels the inflation fluid. The abutment member is shaped to be received on an outer surface of the trocar and adjustable longitudinally of the trocar sleeve so as to be located at a selected position by a manually movable latch collar. The inflatable collar and slidably collar are held connected by a manually operable release.

A small gauge surgical instrument is shown with advantages such as diminished "play" at the tip. A surgical instrument assembly is also shown with support along a length of the instrument that can be selected by the surgeon. Devices and method described provide adjustability of the instrument without protruding into a gripping surface of the instrument.

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.

Medical devices that have a releasable intermediate member and tubular member are described. Methods of using medical devices that have a releasable intermediate member and tubular member are also described. An example medical device comprises an elongate member, an intermediate member, and a tubular member. Each of the intermediate member and tubular member is releasably disposed on the elongate member.

The present invention is directed to tack-free gels and to methods for manufacturing a tack-free gel pad, in which a discontinuous layer of fluorinated ultrahigh molecular weight polyethylene is permanently bonded to the gel pad to provide a tack-free coating. The gel pad may be incorporated into a gel cap to provide a surgical access device having a tack-free surface.
摘要:
A laparoscopic surgical system configured for cooperation with a trocar is described. In another configuration, which is not necessarily exclusive of the first configuration, the system may function to provide an anchoring and closure system for use in laparoscopic surgery.
