US 2025/0017620 A1 · TOOLS AND METHODS FOR VAGINAL ACCESS

Abstract

Trocar components and methods of use are described, wherein the trocar components are configured to provide access to intraperitoneal space via the rectouterine pouch to surgical tools, which optionally include one or more surgical robot members. The surgical tools are optionally 5 mm or more in diameter. In some embodiments, a cannula part has a lumen sized to provide to a plurality of the surgical tools simultaneous transvaginal access to the intraperitoneal space via the rectouterine pouch. In some embodiments, an incision sized to receive a distal aperture of the cannula is created, optionally using one or two dilators. The dilators are sized to create (optionally starting from a puncture by a needle 2 mm in diameter or less) an oblong aperture. In some embodiments, the oblong aperture is at least twice as wide across a long diameter as across a short diameter. An access port for sealing an opening of a natural orifice and supplying access to a body cavity through the natural orifice including: a sealing unit; an unobstructed single lumen cannula extending to the body cavity; a connector connecting the cannula to the sealing unit; an access opening through the sealing unit to the single lumen; a cap including a plurality of cap openings configured to seal between medical instruments inserted into the openings and the access opening.

Dependent claims

A surgery system for providing intraperitoneal access via a body recess, comprising:

a. a stepped dilator comprising:
a dilator body having a longitudinal axis in proximal to distal direction;
a first tapered region of the dilator body tapering narrower toward a distal end of the dilator body, the first tapered region having a blunted distal-most portion having a port;
a second tapered region of the dilator body tapering narrower in a distal direction, located proximally to the first tapered region, and separated from the first tapered region by an isolating intervening region, the isolating region being at least 3 mm long;
and
b. a trocar needle shaped and sized to be passed through the port of the distal-most portion of the first tapered region of the dilator body of the stepped dilator so that a distal tip of the trocar needle extends from the port;
and
c. a cannula shaped and sized to be disposed over the stepped dilator,
the cannula having distal aperture which is slanted relative to the longitudinal axis of the cannula, an edge of the aperture comprising a first edge portion extending along one side of the aperture, and a second edge portion extending along another side of the aperture, wherein the first edge portion extends along a side more distal along the longitudinal axis of the cannula than the second edge portion.
