  • Patent number: 10639038
    Abstract: A surgical instrument includes a body, a shaft assembly, an end effector, and an electrical contact assembly. The body includes a power source. The shaft assembly extends distally from the body, the end effector is distal of the shaft assembly. The end effector includes a channel assembly and a cartridge assembly. The cartridge assembly may selectively couple with the channel assembly. The cartridge assembly includes an electrically activated component. The electrical contact assembly is configured to electrically couple the power source with the electrically activated component. The electrical contact assembly includes a first electrical contact associated with the channel assembly, a second electrical contact associated with the channel assembly, and a hydrophobic layer extending between the first electrical contact and the second electrical contact.
    Type: Grant

  • Patent number: 10631860
    Abstract: A surgical instrument includes a body, a shaft assembly, an end effector, and an electrical contact assembly. The includes a power source, while the shaft assembly extends distally from the body. The end effector includes a channel assembly and a cartridge assembly configured to selectively couple with the channel assembly. The cartridge assembly includes an electrically activated component. The electrical contact assembly is capable of electrically coupling the power source with the electrically activated component of the cartridge assembly. The electrical contact assembly includes a first electrical contact, a second electrical contact, and an insulating membrane. The first electrical contact is associated with the channel assembly while the second electrical contact is associated with the cartridge assembly. The insulating membrane is associated with either the first electrical contact or the second electrical contact.
