SURGICAL DEVICE FOR EXTRACTING A FOREIGN OBJECT AND METHOD FOR MANUFACTURING THEREOF

摘要

A surgical device for removing a foreign object from a body along with a method for manufacturing the surgical device and a retrieval basket of the device are described. The retrieval basket is adapted for entrapping and retaining the object located in the body. The basket comprises a structure having a proximal end and a distal end. The structure is formed by a plurali ty of filaments fabricated from a single or several wires. The filaments extend from the proximal end towards the distal end. At least a part of the filamen ts are overlapped and/or interlaced so as to define a net, and thereby impart structural rigidity and dilatation ability to the basket when opened. The process of manufacturing the retrieval basket includes selecting at least on e wire; weaving the basket from the wire by overlapping and/or interlacing the filaments so that to form a net at least in the vicinity of the distal end; and binding the filaments for forming a shape of the retrieval basket.
