  • Patent number: 11883314
    Abstract: Systems, methods, and devices are described for providing a fluid control for an inflation system. The control directs fluid flow from an inlet to one or more outlets of the control. The outlets are independently connected in fluid communication with the inlet by through the control. The control allows a user to create a fluid path between the inlet and a selected outlet by positioning the control in an orientation corresponding to the desired outlet. Each outlet is independently connected in fluid communication with the inlet in various orientations of the control.

  • Publication number: 20230191017
    Abstract: An ergonomic attachment system for connecting an irrigation tube or an aspiration tube to a surgical handpiece that reduces surgeon wrist fatigue due to tubing twist. The tube is connected to the handpiece through a swivel joint which allows the tube to rotate circumferentially with respect to the handpiece and self-adjust to a neutral position to relieve the twist.

  • Publication number: 20230122206
    Abstract: Systems, methods, and devices are described for providing a brace having an inflation control. The control directs fluid flow from an inflation component to one or more inflatable cells of the brace. The inflatable cells are independently inflated and deflated by the inflation component through the control. The control allows a user to create a fluid path between the inflation component and one of the inflatable cells by positioning the control in an orientation corresponding to the desired inflatable cells. Each inflatable cell is independently inflated and deflated in various orientations of the control.

  • Publication number: 20220087699
    Abstract: A surgical handpiece nosecone having an end overmold portion and/or an internal overmold portion. The end overmold portion is located at an end of the nosecone and compressed between the surgical handpiece housing and nosecone. The internal overmold portion is positioned radially about the nosecone on the inner surface to provide a fluid tight seal that prevents ingress of irrigation fluid into the housing.
