Medical device configured to retrieve calcified stones from the human body

摘要

A medical device configured to retrieve calcified stones from the human body includes wire segments and a fixing disc element coupled with the wire segments. The wire segments form a wire basket. The fixing disc element is coupled with the wire segments at a front end of the wire basket. Multiple adjacent wire strands are formed from a first of the wire segments that is directed along a path extending from the rear end of the wire basket forward through a first through-opening of the fixing disc element, and looped through a second through-opening of the fixing disc element, and directed along a path extending from the fixing disc element rearward to the rear end of the wire basket to thus form a first U-shaped deflection disposed on a distal side of the fixing disc element at the front end of the wire basket.

主权项

1. A medical device configured to retrieve calcified stones from the human body, the medical device comprising:
a plurality of wire segments that are formed to provide a wire basket, the wire segments extending between a front end of the wire basket and a rear end of the wire basket to define an openable basket shape; and a fixing disc element coupled with the plurality of wire segments at the front end of the wire basket, the fixing disc element including a first through-opening, a second through-opening, a third through-opening, and a fourth through-opening; wherein two adjacent wire strands are formed from a first of the plurality of wire segments that is directed along a path extending from the rear end of the wire basket forward through the first through-opening of the fixing disc element, and looped through the second through-opening of the fixing disc element, and directed along a path extending from the fixing disc element rearward to the rear end of the wire basket to thus form a first U-shaped deflection disposed on a distal side of the fixing disc element at the front end of the wire basket; wherein two additional adjacent wire strands are formed from a second of the plurality of wire segments that is directed along a path extending from the rear end of the wire basket forward through the third through-opening of the fixing disc element, and looped through the fourth through-opening of the fixing disc element, and directed along a path extending from the fixing disc element rearward to the rear end of the wire basket to thus form a second U-shaped deflection disposed on the distal side of the fixing disc element at the front end of the wire basket; wherein the first U-shaped deflection is substantially parallel to the second U-shaped deflection.
