Foreign object extractor

摘要

The foreign object extractor has an elongated hollow tube with a central lumen through its entire length providing fluid connection between an engaging end and a vacuum source. The engaging end has a nominally round transverse cross-section and is shaped to engage a foreign object to be removed from the human body. The engaging end flares so as to expose the internal surface of the elongated hollow tube for engagement with the foreign object. An adhesive is disposed on the exposed internal flared surface of the distal end. Pneumatic suction is applied through the lumen of the extractor and the suction serves to bring the foreign object into contact with the adhesive coated surface of the extractor to form a bond between the extractor and the object to be extracted.

主权项

1. An extractor for seizing and removing a foreign object from a natural orifice of the human body, the extractor comprising:
a vacuum source; and an elongate body having a lumen extending through the entire length of the elongate body, a first end of the elongate body being a flared engaging end and a second end of the elongate body opposite the first end being connected to the vacuum source so that the vacuum source is in fluid communication with the lumen and configured to draw suction through the flared engaging end, wherein the flared engaging end comprises paddle-shaped grippers having an adhesive coated on the paddle-shaped grippers configured to contact the foreign object, and wherein each paddle-shaped gripper includes a manually-bendable member such that the paddle-shaped grippers can be bent to customize a shape of the flared engaging end before the flared engaging end is inserted into the natural orifice of the human body to remove the foreign object.
