Description

Appendix calculus removal basket

Technical Field

The invention relates to the technical field of medical equipment, in particular to an appendix calculus removing basket.

Background

At present, stone-forming diseases are common diseases in all countries of the world, and are mainly induced by irregular diet. According to epidemiological investigation, the incidence rate of gallstones in big cities of China is nearly 10 percent, and the incidence rate of gallstones in partial cities can even reach 5 to 1; in the United states, the incidence of gallstone is 10% to 15%, about 100 million patients are newly diagnosed with gallstones each year, and about 70 million patients are subjected to a cholecystectomy each year.

The treatment of the disease generally adopts a surgical operation treatment mode, namely, the tissues of a bile duct and the like of a patient are cut, and the calculus at the calculus part is directly taken out; however, the operation brings much pain to patients, the wound is large, the recovery period after the operation is long, and the operation cost is high. The other method is to adopt a minimally invasive surgery method for treatment, namely, a larger calculus is treated by methods such as ultrasound and the like, then the larger calculus is taken to the affected part by devices such as a calculus taking basket and the like, and the calculus is directly taken out by the devices.

Compared with the traditional surgical operation, the use of the stone-taking basket has the advantages of small wound, less pain and more clinical favor. However, the calculus removing basket is essentially a group of clamping and collecting devices with basket net structures consisting of fine metal wires, and the calculus removing basket is in a binding state when entering a human body, but the external structure of the metal wires easily scratches the inside of the human body to cause hemorrhage of the appendix cavity of a patient, so that the existing calculus removing basket cannot provide sufficient protection for the appendix cavity of the patient.

In view of the above, the invention provides a appendix calculus removing basket.
