  • Publication number: 20230190087
    Abstract: A surgical system includes a fluid-delivery device configured to deliver fluid to a surgical site, a surgical instrument including a heat-generating component, and a fluid inflow path defined from a fluid source to the fluid-delivery device to provide fluid to the fluid-delivery device for delivery to the surgical site. At least a portion of the fluid inflow path is thermally coupled to the heat-generating component to simultaneously draw heat from the heat-generating component and warm fluid flowing through the fluid inflow path. A method of surgery includes using a surgical instrument having a heat-generating component that generates heat during use, and introducing fluid along a fluid inflow path from a fluid source to a surgical site. At least a portion of the fluid inflow path is thermally coupled to the heat-generating component to simultaneously draw heat from the heat-generating component and warm the fluid introduced along the fluid inflow path.

  • Patent number: 11666351
    Abstract: A tissue specimen retrieval device includes a housing, an outer shaft extending from the housing, an end effector assembly extending from the outer shaft, an actuator associated with the housing, and an articulation mechanism operably coupled between the actuator and the end effector assembly. The articulation mechanism includes an articulation block supporting the end effector assembly thereon and is rotatable between first and second orientations to articulate the end effector assembly. A spring biases the articulation block towards the second orientation. An actuation sleeve is slidable relative to the articulation block, in response to actuation of the actuator, from an engaged position, wherein the actuation sleeve is disposed about and retains the articulation block in the first orientation, to a disengaged position, wherein the actuation sleeve is spaced from the articulation block such that the articulation block rotates to the second orientation to articulate the end effector assembly.

  • Patent number: 11622787
    Abstract: A tissue resecting instrument includes a housing, a shaft rotatable relative to the housing and defining a proximal end portion disposed within the housing and a distal end portion distally-spaced from the housing, a cutting member operably associated with the distal end portion of the shaft, a turbine disposed within the housing and operably associated with the proximal end portion of the shaft, and a fluid outflow tube operably associated with the housing. The fluid outflow tube is adapted to connect to a suction source to enable the suctioning of fluid and resected tissue proximally through a lumen of the shaft, an interior of the housing, and into the fluid outflow tube. The turbine is configured such that proximal fluid flow across the plurality of fins of the turbine urges the turbine to rotate, thereby rotating the shaft relative to the housing to enable tissue resection with the cutting member.
