Description
Technical Field
The utility model relates to a medical auxiliary instrument especially relates to a door vein cancer is tied and bile duct cancer is tied and is treated subassembly.
Background
The main function of the hepatic portal vein is to transport nutrients absorbed by the small intestine to the liver for metabolism and to explain toxic substances, and the hepatic portal vein is a blood vessel from the vein to the vein, and the bile duct accompanies with the hepatic portal vein and is the excretion system of the liver, and mainly discharges bile secreted by the liver. The hepatic portal vein and bile duct cancer embolus is a complication of liver cancer patients, particularly late-stage liver cancer patients, and the clinical incidence rate is up to 60-90%. The percutaneous puncture hepatic portal vein radioactive particle implantation is a common treatment method for portal vein cancer embolus and bile duct cancer embolus, and can achieve a better treatment purpose. During the existing treatment, a puncture needle is inserted into a cancer suppository of a portal vein or a bile duct of a patient, then a needle core is drawn out, an outer sheath of the puncture needle is kept in the cancer suppository, radioactive ions are implanted into the cancer suppository through the outer sheath, a small amount of radioactive particles are implanted into the cancer suppository for multiple times, and the operation is troublesome; and the residual radioactive particles after the treatment can not be taken out, so that the liquidity of the portal vein or the bile duct is easily influenced, and once cancer cells in the cancer embolus are killed, the radioactive particles are easy to migrate, so that potential safety hazards exist.
Disclosure of Invention
An object of the utility model is to provide a treatment subassembly is tied to portal vein cancer and bile duct cancer, can accurate control radioactive particle quantity, reduce and implant the number of times, effectively avoid the radioactive ion to remain, improve the security.
In order to achieve the above purpose, the utility model adopts the following technical proposal:
the portal vein cancer embolus and bile duct cancer embolus treatment component comprises a puncture needle outer sheath, a puncture needle core matched with the puncture needle outer sheath, and a particle tube matched with the puncture needle outer sheath, wherein the particle tube consists of a left solid core section with the length of 13-16 cm and a transparent right cavity section, scale marks are arranged on the right cavity section, the reading corresponding to the scale marks is sequentially increased from left to right, a single row of iodine-125 radioactive particles are filled in the right cavity section, and gel is hermetically filled at the orifice of the right cavity section; the needle point of the puncture needle core is of a triangular bevel needle structure.
The left end part of the left solid core section is movably provided with a fixing buckle, the fixing buckle is provided with a bonding sheet, the bonding sheet is provided with a bonding layer, and the bonding layer is covered with a protective film.
The utility model has the advantages of simple structure, can control the length of the radioactive particle chain according to the length of the portal vein or bile duct cancer embolus, accurately control the particle amount, reduce the implantation times of the particles, take out the residual particles from the body through the particle tube, completely avoid the particle residue, avoid influencing the circulation of the portal vein or bile duct, reduce the migration occurrence probability of the radioactive particles and improve the safety; the particle tube is fixed on the skin of a patient through the fixing buckle and the adhesive sheet, so that the stability of the particle tube is ensured, and the pain of the patient is reduced.
