Foreign matter out-taking net bag for endoscope

Abstract

The invention discloses a foreign matter out-taking net bag for an endoscope. The net bag comprises a coil, a cannula and a matter out-taking bag; the coil comprises a coil head, a heat fusion knot and a pull ring, and the coil head and the pull ring are connected to form an integrated part through the heat fusion knot; the cannula sleeves the coil so that the coil can slide in the cannula and contract into the cannula; the matter out-taking bag is conical or cylindrical and is provided with an opening; the coil head is tightly glued to the outer edge of the opening of the matter out-taking bag to make the opening of the matter out-taking bag fixed on the coil head. By means of the foreign matter out-taking net bag, foreign matter can be quickly and accurately captured in the body cavity of a patient through the matter out-taking bag, in the retracing and dragging process, the foreign matter is stable and unlikely to fall from the matter out-taking bag, and it is ensured that the long-strip-shaped foreign matter is in the axial direction of the cannula, so that the long-strip-shaped foreign matter is partially or completely stored in the cannula conveniently, and therefore the long-strip-shaped foreign matter is taken out conveniently.

Description

technical field [0001] The invention relates to a medical device accessory, in particular to a net bag for collecting foreign bodies for an endoscope. Background technique [0002] With the maturity of endoscopic technology, foreign bodies in the upper gastrointestinal tract can be removed directly through endoscopic treatment, thereby avoiding surgery. This method is less traumatic and the patient recovers quickly. With the advancement of technology, more and more patients choose minimally invasive surgery for foreign body removal under endoscopy. [0003] When removing foreign bodies through endoscopic minimally invasive surgery, the main removal tool is a mesh basket. Usually, the mesh basket is a helical structure composed of several metal wires, compressed into the sheath before use, and placed on the foreign body site under the guidance of the endoscope. At the far end, after the sheath is withdrawn, the basket is released and opened into a mesh shape. By dragging an...
