Description

Drainage tube suit capable of arranging particles and adjusting particle positions Technical Field The utility model relates to the field of medical instruments, in particular to a drainage tube capable of being used for placing particles in a portable manner. Background In medical clinic, when a patient suffers from cholangiocarcinoma, tumors block bile ducts, so that bile cannot circulate normally, the internal pressure of the bile ducts is increased, and complications such as acute pancreatitis, biliary liver abscess and the like are induced. For the symptoms, the currently adopted treatment method is that a drainage tube is used for penetrating through the narrow part of a bile duct of a patient to drain bile at the upper end of the narrow part, so that the pressure at the upper end of the narrow part is reduced, and meanwhile, the cancer cells at the narrow part of the bile duct are subjected to radiotherapy through the radioactivity of iodine 125 particles. The main method for placing iodine 125 particles at the bile duct stenosis of a patient in the current industry comprises 1, permanently placing the iodine 125 particles at the bile duct stenosis of the patient directly by a particle needle or other placement devices; the permanent placement method has the defects that after the iodine 125 particles are permanently placed in the narrow position of a bile duct of a patient, the iodine 125 particles are difficult to take out from the body, the iodine 125 particles are permanently present in the body without taking out the iodine 125 particles, meanwhile, after the narrow position of the bile duct is usually caused, the pressure at the upper end of the narrow position is overlarge, a support or a drainage mode is needed to relieve pressure, generally, radioactive particles are needed to be placed in the catheter or the support for pressure relief, the pressure relief cannot be completed in one step, 2, a drainage tube is designed into a multi-cavity structure, such as a 3-cavity structure, 1 cavity is used for drainage, and 2 cavities are used for placing the iodine 125 particles, the iodine 125 particles are placed in the multi-cavity drainage tube, the defect that the particles cannot be taken out after being placed in the cavity of the catheter, and the particles are replaced again when the catheter is needed to be replaced, the same as the catheter is needed, so that the cost of the patient is increased, and a doctor needs to do a tube replacement operation again, pain is brought to the patient, meanwhile, the position of the particles cannot be conveniently adjusted, the existing product is adjusted, the particle position is adjusted according to judging that the position of the particles is cut down, the particle is easy to be placed, the position is needed to be fixed, and the particle is required to be plugged, and the particle is fixed, and once the particle is actually placed in the cavity is required to be replaced, and is fixed, and the particle is once the particle is required to be inserted into the cavity, and is fixed, and the particle is difficult to be fixed, the placed particles also need to be removed together.
