Publication number: 20220117629Abstract: Systems for insufflation and recirculation of insufflation fluid in a surgical procedure include a control unit having a fluid pump, a supply conduit, a return fluid conduit and a pressure-controlled valve. The pressure-controlled valve is in fluid communication with an insufflation gas supply, the supply conduit and the return conduit and is adapted and configured to respond to pressure control signals to adjust position and thereby system flow parameters, to reduce entrainment of air from the surrounding environment, and to increase the concentration of insufflation gas in an operative space, and/or to reduce an overpressure condition in the operative space.Type: ApplicationFiled: November 9, 2021Publication date: April 21, 2022Applicant: Conmed CorporationInventors: Ralph Stearns, Kurt Azarbarzin, Timothy J.

Publication number: 20210284515Abstract: A tool for opening the lid of a paint can consists of an elongated, generally planar, metal plate with a handle portion and a widened end having a concave edge configuration with contact areas at opposite ends of the edge for engaging the lid of a paint can at two spaced locations. The concave edge is also formed with a bend that deviates from a plane in which the handle portion of the plate lies. The bend allows the end of the tool to be inserted into a recess surrounding the paint can lid despite the spacing of the two contact areas. The tool allows the paint can lid to be pried open by prying motions at a small number of circumferentially spaced locations, and avoids the concentration of force that results in lid deformation in the case of a conventional prying tool.Type: ApplicationFiled: March 11, 2020Publication date: September 16, 2021Inventor: Timothy J.
