Pre-tightened positioning apparatus and tissue ligation system apparatus

Abstract

The present application provides a pre-tightened positioning apparatus and a tissue ligation system apparatus. The pre-tightened positioning apparatus comprises a supporting assembly and a tightening thread. The supporting assembly is provided with a distal end and a proximal end. A plurality of inner elastic connectors are disposed circumferentially along the supporting assembly. The tightening thread sequentially passes through the plurality of inner elastic connectors. An end portion of the tightening thread extends out of the distal end of the supporting assembly. An outer elastic connector is disposed on an outer surface of the supporting assembly, and the outer elastic connector is wrapped around the supporting assembly, the inner elastic connectors, and the tightening thread. The present application accurately captures the target tissue, achieves the integration of positioning capture and tissue ligation, and improves the ligation success rate.
