摘要：
Exemplary embodiments of the present disclosure relate to devices, systems, and methods for tissue resection in a body lumen of a patient, and may include an elongate body having a cavity at a distal end and a tissue retractor extendable distally from the distal end of the elongate body. The tissue retractor may include an expansion mechanism. The expansion mechanism may include a plurality of arms each having a first end coupled around a distal cap and expandable radially outward from the distal cap such that an anchoring mechanism on a second end of the arms is engageable with selected tissue for resection of the body lumen. The tissue resection device may further include a tissue resecting device.
