Patent number: 10959747Abstract: Devices, systems, and methods of the present disclosure are directed to efficient and accurate removal of tissue from a three-dimensional anatomic structure, such as a breast, of a patient. For example, a cup can be positioned on the patient's breast to conform the breast (e.g. via suction) to a known three-dimensional contour, and a cutting tip can be moved along the three-dimensional contour at one or more predetermined distances from at least one surface of the cup. The cutting tip can remove tissue along the three-dimensional contour to form a skin envelope. As compared to a manual process performed by a surgeon, formation of the envelope through controlled movement of the cutting tip along the three-dimensional contour can improve control over dimensions of the envelope, thus, facilitating achievement of consistent outcomes by reducing the likelihood of complications associated with an envelope that is too thick, too thin, or uneven.Type: GrantFiled: April 2, 2019Date of Patent: March 30, 2021Inventor: Lifei Guo
