Description

Crooked stone basket of getting
Technical Field
The invention belongs to the technical field of medical instrument manufacturing, relates to a minimally invasive medical technology and a surgical instrument, is used for a duodenoscope lithotomy instrument, and particularly relates to a curved lithotomy basket catheter.
Background
Common bile duct stones are common diseases and frequently encountered diseases in China, the stones block common bile ducts to induce complications such as acute cholangitis, obstructive jaundice and acute cholangiogenic pancreatitis, the symptoms such as shivering, fever, abdominal pain and jaundice appear, serious patients even cause shock, and long-term stone stimulation has the risk of bile duct cancer, so that the common bile duct stones are important diseases which harm human health.
Endoscopic retrograde cholangiopancreatography is a first-line treatment scheme for treating common bile duct calculi at present, and is particularly suitable for patients with general anesthesia biliary tract exploration contraindications, such as heart-lung dysfunction, blood coagulation dysfunction and the like, or patients with high risk in general anesthesia biliary tract exploration, such as no expansion of common bile duct, multiple operation history of upper abdomen and the like. Basket and sacculus are the main work that the stone was got to scope retrograde cholangiopancreatography art, and wherein great calculus can use the rubble basket rubble, and medium-size calculus can use gets the stone basket and take out, and less calculus or silt appearance calculus can use gets the stone sacculus and take out.
The stone-taking basket and the stone-breaking basket are mainly formed by connecting four metal wires in a spiral shape, a diamond shape, a water drop shape and an arc shape. When the calculus is removed by the endoscopic retrograde cholangiopancreatography, the calculus removing basket catheter is firstly placed above the choledocholithiasis, the basket is opened, then the calculus removing basket catheter is pulled outwards, the calculus enters the basket through a gap between the two metal wires, and finally the basket is tightened to remove or strain the calculus.
The calculus removing basket and the calculus crushing basket conduit are straight heads, and the calculus removing basket and the calculus crushing basket conduit are difficult to place into the common bile duct through the duodenal papilla due to the fact that the axial direction of the duodenal clamp is an acute angle with the axial direction of the common bile duct. Therefore, in order to make the calculus removing basket enter the common bile duct conveniently, when the calculus removing basket catheter is placed in the duodenoscope forceps channel, the head of the calculus removing basket catheter needs to be shaped, but after the calculus is removed once, the head of the catheter becomes straight again, the head of the catheter needs to be taken out again for shaping, and the calculus removing time is greatly prolonged. The outer tube of rubble basket is the tubular metal resonator, consequently is difficult to carry out moulding to rubble basket outer sheath pipe head end, and the basket need can get into common bile duct in the guide below of seal wire more, even take the seal wire guide, and the rubble basket gets into common bile duct's degree of difficulty through the duodenum nipple still great, easily damages duodenum nipple sphincter and pancreatic duct sphincter, leads to the emergence of complication such as nipple edema, hemorrhage and acute pancreatitis.
