Patent number: 9955992Abstract: The invention relates to a tissue morcellator for minimally invasive surgery. The morcellator has a metallic cutting ring mounted on a visually transparent hollow cylinder, which in combination with a visually transparent outer morcellator tube enables a surgeon to visualize the inside of the morcellator shaft for detection of loose tissue fragments in the device. A tenaculum used with the morcellation device has a spacer for preventing contact with the blade. The cutting tube can oscillate, rather than rotate, along the longitudinal axis of the cutting tube. The morcellator utilizes an extendable tissue guide on the outer tube of the morcellator shaft for preventing the tissue from rotating along the longitudinal axis of the morcellator tube. This allows the tissue to be continuously rotated into the morcellator device for continuous peel. The tissue guide can also be fully retracted to allow for coring of the bulk tissue.Type: GrantFiled: October 24, 2012Date of Patent: May 1, 2018Assignee: Applied Medical Resources CorporationInventors: Boun Pravong, Kennii Pravongviengkham, Matthew M.

Publication number: 20160174960Abstract: A retraction device that optionally includes a sheath that traverses from outside the body to a body cavity inside the body. The retraction device may include an outer retention ring and a plurality of shapeable extending elements coupled to the retention ring and extending distally therefrom, the extending elements being configured to transition from a first, low-profile, insertion condition to a second, expanded, high-profile retention condition in which distal ends of the extending elements extend radially outwardly. Alternatively, the retraction device may include an outer ring having a substantially annular shape with an adjustable circumference, the outer ring being divided into a plurality of curved ring segments, with a substantially tubular structure extending distally from the outer ring, wherein the diameter of the outer ring is increased by moving the curved ring segments further apart and the diameter is decreased by moving the curved ring segments closer together.Type: ApplicationFiled: February 29, 2016Publication date: June 23, 2016Inventors: Jeremy J.
