    摘要： An endoscopic bipolar forceps includes a housing having a shaft affixed thereto, the shaft including jaw members at a distal end thereof. The shaft includes a longitudinal axis defined therethrough and the jaw members are adapted to connect to a source of electrosurgical energy such that the jaw members are capable of conducting energy through tissue held therebetween to effect a tissue seal. The forceps also includes a drive assembly which moves the jaw member relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members are closer to one another for manipulating tissue. A movable handle is included which is rotatable about a pivot to force the drive assembly to move the jaw members between the first and second positions. The pivot is located a fixed distance above the longitudinal axis. A knife assembly is also included which has a movable knife bar having a generally t-shaped proximal end dimensioned to operatively engage a corresponding slot defined within the housing, the slot being dimensioned to guide the movement of the knife bar during translation thereof.

    摘要： The present disclosure relates to a forceps that includes a housing, a cutting assembly, and an actuator. The housing has a shaft attached thereto that extends therefrom and is configured to support a pair of jaw members at a distal end thereof. The jaw members are movable to grasp tissue therebetween. The cutting assembly includes a spring element that has proximal and distal ends. The proximal end of the spring element is fixed to a boss disposed within the housing and the distal end of the spring element includes a cutting edge. The spring element is coiled at a proximal end thereof to create a spring bias against the boss. The actuator is operably coupled to the spring element and is configured to selectively advance the cutting edge of the spring element into the jaw members against the spring bias to sever tissue disposed therebetween.

    摘要： The present disclosure relates to a connector hub assembly. The connector hub assembly includes a housing and a retention device. The housing has a connector bank having one or more input ports and one or more output ports, that are defined therein. The input ports are configured to operably connect to one or more first conduits and the output ports are configured to operably connect to one or more second conduits. The retention device is operably coupled to the housing. The retention device includes a flexible membrane that has one or more slits defined therethrough that form flexible segments in the membrane. The flexible segments are configured to selectively secure the connector hub assembly to a sheet-like material when the sheet-like material is fed through the slits.

    摘要： A removable electrode assembly for use in combination with a forceps having opposing end effectors and a handle for effecting movement of the end effectors relative to one another. The electrode assembly includes a housing which is removably engageable with the forceps and a pair of electrodes which are attachable to a distal end of the housing. The electrodes are removably engageable with the end effectors of the forceps such that the electrodes reside in opposing relation relative to one another. The electrode assembly also includes a cover plate which is removably attachable to the housing and at least one stop member for controlling the distance between the opposing electrodes. The stop member is selectively engageable with the electrodes.
