Problems solved by technology

At present, clinically, for patients with biliary obstruction who cannot undergo surgery, percutaneous hepatic puncture is often used to place a biliary drainage tube to solve the problem of biliary obstruction (that is, the circulation of bile is realized through the biliary drainage tube), but this The method cannot treat biliary obstruction and eradicate biliary stenosis, so patients need to carry biliary drainage tubes for a long time and need to be replaced regularly, which increases the cost of treatment

Embodiment approach 1

[0033] Such as figure 1 and 4 , 5, the percutaneous liver puncture implantation type multifunctional biliary drainage device according to the present invention includes a drainage tube 1, a flexible expansion stent and a development marking part arranged on the drainage tube 1, and a flexible expansion stent arranged on the flexible expansion stent. The radiation particle bar 2 includes the particle tube 2.1 and the radiation particles packaged in the particle tube 2.1 (the radiation particle is iodine 125 radiation particle, with a diameter of about 0.8 mm and a length of about 4.5 mm).

[0034] Such as figure 1 As shown, the outer surface of the tube wall of the drainage tube 1 has a developing layer, which can be developed under the imaging equipment, so as to facilitate tracking the position of the drainage tube 1, and there is a length scale mark on the drainage tube 1, so as to determine the length and The position of the flexible airbag 3.1 described later; the draina...

Embodiment approach 2

[0042] The difference between the percutaneous hepatic puncture-implantable biliary drainage device described in this embodiment and the first embodiment lies in that the structure of the pipeline communicated with the flexible balloon 3.1 is different. Specifically: if Figure 6 As shown, the pipeline of this embodiment includes an inlet and outlet hole 6 provided on the wall of the drainage tube 1 and a connecting tube head 3.3 arranged on the outer end of the drainage tube 1. One end of the inlet and outlet hole 6 is communicated with the flexible air bag 3.1 and one end thereof It communicates with the connecting pipe head 3.3, and inserts a silicone plug 3.4 into the port of the connecting pipe head 3.3 (or sets a regulating valve on the connecting pipe head 3.3).

Embodiment approach 3

[0044] The difference between the percutaneous liver puncture implantable multifunctional biliary drainage device in this embodiment and the first embodiment lies in that the specific structures of the drainage tube 1 and the flexible expansion stent are different. details as follows:

[0045] Such as Figure 7 As shown, the drainage tube is a Y-shaped structure, which includes a drainage main pipe 1.2 and two drainage branch pipes 1.3 connected to the right port of the drainage main pipe 1.2, and the angle between the two drainage branch pipes 1.3 is 45° to 90°; The structures of the two drainage branch tubes 1.3 are the same, including a connecting section connected with the drainage branch tube 1.3 and a curled section extending into the bile duct (this section is a pigtail tube structure), and the curled section can be in a straightened state under the action of the guide wire , when the guide wire is pulled out, the curled sections are automatically wound together (the c...

Abstract

The invention discloses a percutaneous transhepatic implanted multifunctional biliary drainage device. The percutaneous transhepatic implanted multifunctional biliary drainage device comprises a drainage tube, a flexible expansion stent, radioactive particle strips and a development mark part, wherein the flexible expansion stent is arranged at the right end part of the drainage tube; the radioactive particle strips are arranged on the flexible expansion stent; the development mark part is arranged on the drainage tube at two sides of the flexible expansion stent and is developed under imagingequipment; first drainage holes are formed in the drainage tube at the left side of the flexible expansion stent; and second drainage holes are formed in the drainage tube at the right side of the flexible expansion stent. The percutaneous transhepatic implanted multifunctional biliary drainage device has the advantages that the expansion stent is integrated on the drainage tube, a flexible airbag can expand an obstructive site while meeting bile drainage, and radioactive particles on the flexible airbag can carry out radiation therapy on tumor tissues at the obstructive site at the same time, so that the carrying time of patients is effectively shortened; the drainage tube can be linear and meets the requirements of bile drainage, obstruction expansion and tumor tissue treatment of single duct obstruction; and the drainage tube can be of a Y-shaped structure, and meets the treatment requirements of the patients with hilar biliary duct obstruction.

Description

technical field [0001] The invention relates to a medical device, in particular to a percutaneous liver puncture implanted multifunctional biliary tract drainage device. Background technique [0002] Malignant biliary obstruction refers to a series of symptoms caused by the blockage of bile flow caused by tumors in and out of the bile duct oppressing bile ducts at all levels. The disease is common in cholangiocarcinoma and extrahepatic metastases. Once biliary obstruction occurs, it can cause liver failure, coagulation dysfunction, biliary infection, and even endanger the life of the patient. At present, clinically, for patients with biliary obstruction who cannot undergo surgery, percutaneous hepatic puncture is often used to place a biliary drainage tube to solve the problem of biliary obstruction (that is, the flow of bile is realized through the biliary drainage tube), but this Methods The biliary obstruction cannot be treated and the biliary stricture cannot be eradic...
