Publication number: 20140276806Abstract: In the case of an instrument (10) for coagulation and fusion as well as for severing vessels, provision is made for two shanks (19, 20), between which a vessel is to be gripped and fused. A blade (21) for severing the coagulated and fused vessel is provided with an isolator (40), which isolates the blade (21) against at least one of the electrodes or shanks (19, 20), respectively. On the other hand, the blade (21) is preferably in mechanical contact with at least one of the electrodes or shanks (19, 20), respectively, so that a safe separation of the fused biological tissue or vessel, respectively, is attained. This concept can be used to increase the safety of surgery and to miniaturize the tool (18) towards smaller sizes.Type: ApplicationFiled: March 13, 2014Publication date: September 18, 2014Applicant: ERBE Elektromedizin GmbHInventor: Martina Heim

Publication number: 20140276803Abstract: An electrosurgical forceps is provided with a shaft that extends from a housing of the electrosurgical forceps. An end effector assembly operably coupled to a distal end of the shaft includes a pair of first and second jaw members having proximal and distal ends. One or both of the first and second jaw members is movable from an open configuration for positioning tissue therebetween, to a clamping configuration for grasping tissue therebetween. A knife blade assembly includes a knife blade that is translatable within the first and second jaw members when the first and second jaw members are in the clamping configuration. The knife blade assembly includes a knife blade stop configured to contact at least a portion of the proximal end of the second jaw member when the first and second jaw members are in the open configuration to limit translation of the knife blade assembly.Type: ApplicationFiled: January 10, 2014Publication date: September 18, 2014Applicant: COVIDIEN LPInventor: KEIR HART

Publication number: 20140276802Abstract: A surgical instrument includes a first member having an inner surface defining a first passageway. A second member is disposable within the first passageway and movable relative to the first member. The second member defines a longitudinal axis and extends between a first end and a second end configured to engage tissue. The second end includes a first surface configured for a non-penetrating engagement with the tissue and a second surface including at least two spaced apart cutting members extending axially from the first surface. The cutting members are rotatable to excise a portion of the tissue. Systems and methods are disclosed.Type: ApplicationFiled: March 14, 2013Publication date: September 18, 2014Applicant: Kyphon SARLInventor: Craig E. Lauchner
