Publication number: 20240074809Abstract: A surgical instrument with insulating grips is described. The grips can include internal metal frames that are arranged to limit electrical conductivity within the grips and to other components that attach to a grip, such as a ratchet. The internal metal frames can be constructed of multiple internal portions, spatially separated from one another to interrupt electrical conductivity between the internal portions, but coated with an insulating overmold to provide mechanical coupling between the portions. An internal metal frame can also include a notch, cut-out, or other region partially surrounded by the structure of the internal metal frame, which can be coated with an insulating overmold to define a region of the grip that does not have an internal metal frame therein but which can include an attachment point for mechanically coupling other components while limiting electrical coupling between the metal frame and the other components.Type: ApplicationFiled: October 31, 2023Publication date: March 7, 2024Applicant: Microline Surgical, Inc.Inventors: Christopher Alesi, Dennis Pelletier
