Publication number: 20180014842Abstract: A surgical system can include a first instrument defining a first channel and a second instrument receivable by the first channel. The second instrument can include a second channel. A valve coupled to the first instrument controls fluid flow through the first channel. The valve has at least two positions and in one position, the impedance of fluid flow through the valve into the first channel (when the second instrument is not received in the first channel) is substantially the same as when the valve is the other position and the first channel partially blocked by the second instrument. In another aspect, a surgical system can include an outer member and the first instrument can be received within the outer member to define a second channel there between. The first instrument can include a visualization system and an illumination system.Type: ApplicationFiled: January 28, 2015Publication date: January 18, 2018Inventor: CEMAL SHENER-IRMAKOGLU

Publication number: 20180014843Abstract: An endoscopic surgical blade is disclosed. The blade is of a hook design, having an upper cutting surface located on the trailing edge of an arm and a lower cutting surface on the upper edge of the main body of the blade. The blade is part of an endoscopic knife assembly which also contains a knife tube and alignment ring. The endoscopic knife assembly is for use in endoscopic surgery by insertion of the assembly through a slotted cannula. The knife tube is hollow and allows the insertion of an endoscope for viewing of the surgical procedure. A method for a performing an operative procedure on a target tissue in a subject using an endoscopic knife assembly having a hook blade is also described.Type: ApplicationFiled: May 2, 2017Publication date: January 18, 2018Inventors: Ather MIRZA, Romi Mirza

Publication number: 20180014844Abstract: A method of forming a component of an ultrasonic surgical instrument includes accessing a file including a digital model representing the component. The component includes a proximal portion and a distal portion. The proximal portion includes a contact portion. The distal portion includes an ultrasonic blade. The contact portion is configured to transmit ultrasonic vibrations to the ultrasonic blade when the component is acoustically coupled to a complementary portion of an acoustic waveguide of the ultrasonic surgical instrument. The file is used to fabricate the component via an additive manufacturing process. Once the component has been fabricated, the distal portion is secured to a distal end of the complementary portion of the acoustic waveguide.Type: ApplicationFiled: July 12, 2016Publication date: January 18, 2018Inventor: Sean P. Conlon

Publication number: 20180014846Abstract: A surgical instrument includes a transducer assembly with a housing having a conduit section and a base portion. A fluid passageway is defined through the conduit and base portion, an ultrasonic transducer including a plurality of piezoelectric elements and a plurality of electrodes are arranged in a stack configuration, where an electrode is located between each pair of piezoelectric elements. A first borehole is defined through the ultrasonic transducer and an end mass having a second borehole defined therethrough. A surface of the end mass is positioned adjacent a first end of the ultrasonic transducer, the end mass is configured to engage with the housing, and the conduit section of the housing is configured to pass through the second borehole of the end mass. The end mass is configured to compress the ultrasonic transducer against a surface of the housing when the end mass is engaged with the housing.Type: ApplicationFiled: June 19, 2017Publication date: January 18, 2018Inventors: Sora Rhee, Jacob S. Gee, Steven P. Smolik, Stephen J. Balek, William D. Dannaher, Foster B. Stulen
