Abstract

The present disclosure is directed to arthroscopic visualization systems and methods. The visualization system can include a camera with a fluid inflow path, wherein a proximal end of the camera is configured to fluidly connect a fluid reservoir to the fluid inflow path. The system can also include a cannula with a lumen, wherein the lumen is configured to be fluidly connected to the fluid inflow path at a distal end of the camera. In addition, the system can also include a scope, wherein the scope is configured to be connected to the distal end of the camera and a portion of the scope is configured to be inserted into the lumen of the cannula.

Core Innovation

A visualization system for medical procedures includes a camera having a body longitudinally extending between a proximal end and a distal end and having a fluid inflow path. The proximal end of the camera body is configured to fluidly connect a fluid reservoir to the fluid inflow path, and a cannula includes a lumen configured to be fluidly connected to the fluid inflow path at the distal end of the camera body. A scope is connected to the distal end of the camera body and a portion of the scope is inserted into the lumen of the cannula.

The scope and cannula are rotatably connected to the distal end of the camera body and are configured to rotate independent of the camera body. In implementations that include fluid outflow, the camera further includes a fluid outflow path, with the proximal end configured to fluidly connect the fluid outflow path to a fluid waste. The cannula can comprise first and second lumens, with the first lumen connected to the fluid inflow path and the second lumen connected to the fluid outflow path.

The cannula can comprise a diameter that tapers from a proximal end toward a distal end, and can include an integrated rotation guide. The integrated rotation guide is located on a proximal end of the cannula and is configured to be positioned immediately distal the distal end of the camera body when the scope and cannula are connected to the camera body. The scope can also be configured to be connected to the distal end of the camera body and wirelessly, electrically coupled to the distal end of the camera body.

Claims Coverage

The provided claims show 5 independent inventive claim structures, each centered on a rotatable scope/cannula assembly with defined camera fluid inflow and optional fluid outflow, plus optional cannula geometry, lumen multiplicity, integrated rotation guidance, and wireless electrical coupling.

Across the independent claims, the core coverage is the rotatable connection of a scope and cannula at the distal end of a camera with independent rotation from the camera body, combined with defined fluid inflow and, in one independent claim, fluid outflow to waste via camera-to-cannula fluid pathways. Additional claim coverage includes multi-lumen inflow/outflow routing, optional wireless electrical coupling of the scope to the camera distal end, optional cannula taper geometry, and an integrated cannula rotation guide positioned relative to the camera distal end.
