Vessel sealer and divider for large tissue structures |
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.
