An anti-shrinkage device for a conveyor and a conveyor thereof, wherein the anti-shrinkage device is sleeved on a sheath core tube of a conveyor and is located between an end head of the conveyor and a push rod. The anti-shrinkage device includes at least two hollow anti-retraction members, and the at least two anti-retraction members are arranged at an interval along the length direction of the sheath core tube. The anti-shrinkage device further includes a connection member that connects any two adjacent anti-retraction members among the at least two anti-retraction members.

Anti-shrinkage device used for conveyor and conveyor thereof

Magnetic toy

An implant delivery device includes a holder, a guide rod, and a sliding handle. One end of the guide rod is connected to the holder, and the other end of the guide rod penetrates the sliding handle. Multiple first engagement structures axially spaced apart from each other are disposed on an outer surface of the guide rod. The delivery device also includes a position locking device disposed in the sliding handle. The position locking device includes a tooth block) and an elastic component. The tooth block is sleeved on the guide rod and is provided with a second engagement structure. The elastic component and the tooth block cooperate to allow the first engagement structures and the second engagement structure to engage with each other allowing an implant to be in a release-locked state. These and other elements allow for the implant to be gradually released or release-locked.

Delivery device

A delivery system () for delivering a lumen stent (). The delivery system () comprises a fixing anchor () and a fixing cap () which is cylindrical and has an opening at a proximal end, the fixing anchor () comprising a hollow insertion part () and an abutment part () connected to the insertion part (); parts of the side surface of the insertion part () are recessed towards the interior of the insertion part () to form a plurality of positioning grooves () that extend to a proximal end surface of the insertion part (), a separator () being formed between every adjacent two positioning grooves (); the abutment part () comprises a carrier () and a plurality of first position-limiting pieces () provided on a side of the carrier (), a distal end of each first position-limiting piece () being provided to correspond to an open side of a positioning groove () adjacent to the abutment part (); distal end surfaces of the plurality of first position-limiting pieces (), a distal end surface of the carrier () and proximal end surfaces of the separators () are coplanar. When the fixing anchor () and the fixing cap () are joined, the insertion part () is inserted into the fixing cap (), and the distal end surfaces of the first position-limiting pieces () abut the proximal end surface of the fixing cap (). Further disclosed is a lumen stent system. The delivery system () can be smoothly and safely withdrawn out of the human body.
