  • Publication number: 20190115168
    Abstract: A switch mechanism includes a housing with a fenestration, a switch element held in the housing, and a first tab and a second tab each being pivotally attached to an opposite lateral edge of the fenestration. The tabs are constrained to rotational movement relative to the housing so that contact with the first tab or the second tab causes the respective tab to rotate to actuate the switch element.

  • Publication number: 20180338789
    Abstract: A surgical device employs a longevity circuit for preventing operation after a specified time based on safe use expectations. The surgical device delivers a therapy signal via a handpiece having electrodes in proximity to the surgical site. The therapy signal is a high frequency electrical signal delivered from a generator coupled to the handpiece, and activated by a control signal. A therapy circuit established by coupling the handpiece and generator delivers the therapy signal, and is monitored for activation based on a time since a first activation, a number of activations, or an aggregate time of activated intervals. A usage limit defines the activation lifespan, and is employed for monitoring either the therapy circuit or the control circuit, to determine a usage history. Following expiration of a safe usage limit, a longevity circuit in the handpiece disables the handpiece for successive uses, and is independent of a connection to a particular generator.

  • Publication number: 20180279861
    Abstract: A system comprising: (a) a sheath configured to receive all or a portion of an endoscope; (b) an irrigation line connecting the sheath to an irrigation source; (c) a suction line connecting the sheath to a suction source; and (d) a control module located between the sheath, and the irrigation source and the suction source and controls flow of irrigation fluid from the irrigation source to the sheath and movement of suction between the suction source and the sheath; wherein the irrigation source is connected to a resilient reservoir that is located within the control module and movement of the control module compresses the resilient reservoir moving irrigation fluid from the resilient reservoir to the sheath so that the irrigation fluid assists in cleaning the endoscope, and wherein the control module includes a valve and compression of the resilient reservoir initiates movement of the valve so that the valve opens and suction from the suction line is applied to the sheath.
