Abstract: A tool for use in endoscopic surgical procedures includes a shaft, wherein the shaft includes a first end, a second end, and a first axis; and a pointer at the first end of the shaft, wherein the pointer includes: a tip located on the first end of the pointer, and a plurality of fiducial markers disposed on the pointer, wherein at least one of the fiducial markers is disposed on a surface that extends transversely to the first axis, wherein the plurality of fiducial markers are configured for providing information for locating the tip of the pointer in an endoscopic image captured by an endoscopic imaging device.

Abstract: A method for training a machine learning model to detect substances that compromise medical imaging clarity includes receiving imaging of tissue associated with a medical procedure type; receiving imaging of one or more substances that can affect clarity of imaging associated with the medical procedure type; combining at least a portion of the imaging of the tissue and at least a portion of the imaging of the one or more substances to generate machine learning training image data in which at least a portion of the tissue is at least partially obscured by the one or more substances; and training, with the training image data, a machine learning model to detect the one or more substances in imaging generated during a medical procedure of the medical procedure type.

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.
