Abstract
This invention relates to device, systems, kits and methods that enable selective dissection of lung tissue to remove diseased tissue from healthy tissue without damaging blood vessels or airways. The invention and methods enable minimally invasive lung surgery procedures by providing a device and method to perform automated dissection that discriminates against traumatizing critical lung tissue.
Claims20
A method of removing a portion of a lung from other portions of the lung, the method comprising:
- providing a surgical instrument with a source of work energy that is coupled to a dissecting member extending at a forward portion of the instrument, wherein the forward portion comprises a guard element;
- activating the source of work energy to induce motion of the dissecting member;
- contacting the forward portion of the instrument to a lung tissue and to a lung structure so that the dissecting member contacts the lung structure;
- and
- selectively dissecting lung tissue away from the lung structure with the motion of the dissecting member while the guard element of the forward portion deflects away the lung structure.
A surgical instrument for removing a portion of a lung from other portions of the lung, the surgical instrument comprising:
- an instrument housing having a forward portion and rearward portion;
- a source of work energy in the rearward portion coupled to a drive mechanism in the housing;
- a dissector housing coupled to the forward portion;
- and
- a dissecting member coupled to the dissector housing and operatively coupled to the drive mechanism, wherein the dissecting member has dull edges configured to engage lung tissue without directly cutting the lung tissue, wherein the drive mechanism is configured to move the dissecting member in a reciprocating motion while the dissector housing contacts the lung tissue to provide a pulling force that pulls apart the lung tissue.
