Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a digestive tract foreign body net basket equipped with a protective device. Background Art

[0002] Endoscopic removal of foreign bodies from the digestive tract or bile duct is a method of treating biliary and pancreatic diseases and foreign bodies in the digestive tract through gastroscopy, colonoscopy, duodenoscope, or choledoscopic surgery. It is less invasive and has a quick recovery, especially for removing foreign bodies from the stomach through gastroscopy. If successful, it can avoid the pain and cost of surgical removal of foreign bodies for patients.

[0003] Existing foreign body removal devices include foreign body forceps, snares and baskets. The basket generally includes four basket wires, one end of which is fixed together and housed in an outer sheath, and the other end is either fixedly connected by a metal head or connected by a limit ring. The basket can capture foreign bodies, strangle the foreign bodies and then withdraw to remove them from the digestive tract lumen.

[0004] However, the basket lacks a protective structure for the digestive tract and is prone to causing abrasions or scratches to the mucosa during removal. Utility Model Content

[0005] The present application provides a digestive tract foreign body basket equipped with a protective device to solve the problem that the digestive tract foreign body basket is prone to falling or rubbing against the patient's digestive tract mucosa when removing foreign objects.

[0007] In some embodiments of the present application, the basket includes a basket tightening line connected to the conductive wire, a plurality of mesh wires connected to the basket tightening line, and a limiting ring provided at the free ends of the plurality of mesh wires.

[0008] In some embodiments of the present application, the arc-shaped metal wire and the protective bracket are both nickel-titanium alloy wires.

[0009] In some embodiments of the present application, the control end is configured as a sleeve, and the conductive wire, tightening wire, and basket tightening wire all pass through the sleeve.

[0010] In some embodiments of the present application, the coverage area of the protective mechanism is not less than one third of the outer surface of the basket.

[0011] In some embodiments of the present application, the covering film is made of rubber.

[0012] In some embodiments of the present application, the thickness of the covering film is no more than 3 mm.

[0013] In some embodiments of the present application, a spacer is provided in the sleeve.

[0014] Compared with the prior art, the present invention has the following characteristics and beneficial effects:

[0015] The utility model can adjust the volume of the net basket and the protective mechanism respectively through the control end, the guide wire, the net basket tightening line and the tightening line. After obtaining the foreign body, the net basket is tightened first and then the protective mechanism is tightened, which facilitates the foreign body to enter the net basket. When the foreign body is taken out, the protective mechanism can prevent the foreign body from scratching or rubbing the digestive tract. When the foreign body accidentally slips, there is a great chance that it will fall into the protective mechanism, which is convenient for operation, can effectively reduce the risk of injury to the patient, shorten the operation time, and can produce better results if promoted and used.
