Abstract
A combination surgical device is provided and includes a dissection blade moveably mounted in a first jaw of the surgical device. The surgical device includes a second jaw movably mounted relative to the first jaw and a handle assembly. The handle assembly includes an advancement mechanism for incrementally advancing the blade out of the first jaw and a lever to open and close the first and second jaws. A lock member is provided to maintain the blade in an extended condition and a release lever is provided to disable the lock member. The surgical device additionally includes a safety or lock out mechanism which prevents the jaws from moving while the blade is in the extended condition.
Claims20
A combination surgical device comprising:
- a handle assembly having a handle housing,
- an elongate tubular member extending distally from the handle assembly and having a distal end, and
- an end effector assembly mounted on the distal end of the elongate tubular member, the end effector assembly including a first jaw, a second jaw and a blade movably mounted within the first jaw.
A combination surgical device comprising:
- a handle assembly having a handle housing,
- an elongate tubular member extending distally from the handle assembly and having a distal end,
- an end effector assembly mounted on the distal end of the elongate tubular member, the end effector assembly including a first jaw, a second jaw movably mounted relative to the first jaw and a blade movably mounted within the first jaw,
