Abstract:
Disclosed is a pair of object removal net forceps, comprising a handle (1), a catheter (2), a pull cable (3), and a plurality of object removal nets (4). The pull cable (3) is arranged inside the catheter (2), with a proximal end thereof being connected to the handle (1), and a distal end thereof being connected to the plurality of object removal nets (4). Each object removal net (4) comprises a net bag (41), and a loop steel wire (42) connected to an edge of an opening of the net bag (41), wherein the loop steel wire (42) is connected to the handle (1) via the pull cable (3), such that the loop steel wire (42) is controlled by the handle (1) to generate elastic deformation in order to open or close the net bag (41); and the loop steel wire (42) is shaped into a bent structure, such that the plurality of object removal nets (4) open with a preset angle therebetween. The object removal net forceps have an improved foreign matter holding capacity due to the plurality of net bags (41), can conveniently remove foreign matter from the patient's body, is flexible in operation, and can remove a large amount of small-volume foreign matter in one step, thereby effectively reducing the number of operations needed for object removal and shortening the operation time.
