  • USE OF THREE-DIMENSIONAL MODELS OF SPECIMENS AND DEFECTS TO ENHANCE COMMUNICATION AND DOCUMENTATION OF FROZEN AND PERMANENT SECTIONS IN CANCER SURGERY
    Publication number: 20260011097
    Abstract: Systems and methods for localizing close or positive margins in a tumor specimen from a subject are provided. A three-dimensional representation of the specimen is obtained, where the representation comprises more than 1000 three-dimensional points that define a boundary of the specimen. A plurality of annotations to the representation is received, including a first subset of annotations indicating an orientation of the representation relative to the subject, a second subset of annotations indicating a plurality of tissue sections from the specimen, and a third subset of annotations providing a margin status for respective tissue sections in the plurality of tissue sections, where the margin status indicates close or positive margins based upon pathological analysis of the respective tissue sections. A composite three-dimensional representation of the tumor specimen is formed by modifying the first three-dimensional representation of the tumor specimen to include the plurality of annotations.

  • Method and apparatus for an indwelling one-way valve prosthesis for hands-free tracheoesophageal speech
    Patent number: 5683458
    Abstract: There is disclosed a sysem for hands-free tracheoesophageal speech in a pent who has undergone a laryngectomy, said system comprising a one-way valve prosthesis adapted to be placed in a stoma surgically created in the anterior wall of the trachea of a patient, said stoma extending through the skin of the patient thereby permitting the passage of air inwardly through the one-way valve prosthesis and into the trachea but not permitting the passage of air from the trachea outwardly through the stoma, supporting means attached to and extending laterally from the one-way valve prosthesis, said supporting means adapted to contact the anterior mucosa of the trachea around the circumference of the stoma and thereby to achieve an airtight seal between the one-way valve prosthesis and tracheal mucosa and to support the one-way valve in place in the stoma, said system thereby permitting hands-free tracheoesophageal speech by preventing exhaled air from passing outwardly through the one-way valve prosthesis and the stom
