Abstract
An introducer accessory for being fitted with a circular stapler is disclosed, and pertains to the technical field of medical instrument. The introducer accessory at least comprises a sleeve portion sleeved around a distal end of the circular stapler and an introducing portion disposed at a distal end of the sleeve portion. And the introducing portion comprises a spiral member in a conical shape with a cavity and a traction member, the traction member extends in the cavity of spiral member to connect with the distal end of the spiral member such that when the traction member is pulled by an external force, the distal end of the spiral member is pulled out by the traction member through the cavity which causes the spiral member to be unwound internally and finally to form a strip body to withdraw through the circular stapler. Thus, the withdrawing process of introducer accessory can avoid injury to patient during surgery.
