An introducer for being fitted with a circular stapler, is a flexible plastic member in a whole shape of conical with an inner cavity; the introducer has a proximal end and a distal end, outer diameter of the introducer is gradually increased from the distal end to the proximal end and a maximum outer diameter of the proximal end is less than or equal to a maximum outer diameter of a staple cartridge assembly; when pulled by an external force, the plastic member may be unwound spirally and finally forms a strip body capable of being disengaged from the circular stapler. The introducer provided by the present disclosure has the advantages that: as the maximum outer diameter of the introducer is approximately equal to the maximum outer diameter of the staple cartridge assembly, the process of introducing can be achieved without bad influence resulting from increasing the outer diameter of the circular stapler. Moreover, the introducer can be pulled out from the circular stapler in one piece in the form of a strip, so that the operation is convenient and no additional step can be added for the subsequent operation of the circular stapler.

Introducer and circular stapler

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.
