摘要： A surgical instrument, comprising: a housing defining a track including a longitudinal portion and an angled portion extending from the longitudinal portion; a first actuation assembly selectively actuatable to deploy a first component; a biasing member coupled at a first end thereof to the first actuation assembly; a pin coupled to a second end of the biasing member and slidably disposed within the track; and a second actuation assembly selectively actuatable to deploy a second component, the second actuation assembly coupled to the first actuation assembly such that actuation of the second actuation assembly also actuates the first actuation assembly, wherein the pin is maintained within the angled portion of the track when the first actuation assembly is actuated such that the biasing member applies a biasing force against actuation of the first actuation assembly, and wherein the pin is moved to the longitudinal portion of the track and slid therealong when the second actuation assembly is actuated such that the biasing member applies a reduced biasing force against actuation of the second actuation assembly.

摘要： A surgical system, comprising an ultrasonic surgical instrument, including a waveguide defining a blade at a distal end thereof and a lumen extending through a portion of the blade, an inflow conduit disposed in communication with the lumen, the inflow conduit configured to supply fluid to the lumen, and a return conduit disposed in communication with the lumen, the return conduit configured to receive fluid from the lumen and a cooling module, including a pump assembly operably coupled to the inflow and return conduits, the pump assembly configured to pump fluid through the inflow conduit, into the lumen, and back through the return conduit for cooling the blade, at least one sensor configured to sense at least one of a property of the fluid pumped into the inflow conduit or a property of the fluid returned from the return conduit, and a controller configured to control the pump assembly according to the at least one sensed property wherein the at least one of the property of the fluid pumped into the inflow conduit or the property of the fluid returned from the return conduit indicates whether an error exists wherein the at least one sensor is configured to sense at least one of a rate of flow of the fluid returned from the return conduit or a rate of flow of the fluid pumped into the inflow conduit, and wherein the controller is configured to determine whether an error exists based upon the at least one rate of flow or wherein the at least one sensor is configured to sense gas bubbles in the fluid returned from the return conduit or gas bubbles in the fluid pumped into the inflow conduit, and wherein the controller is configured to determine whether an error exists based upon the presence of gas bubbles.
