Embodiment 1

[0042] Such as figure 1 , 5As shown, the cobalt-zirconium gold standard implant provided by the present invention includes a gold standard body 1 . Specifically, the gold standard body 1 is made of metal cobalt and zirconium, and its shape is capsule-shaped or drum-shaped, and its outer surface is provided with lines 3 for increasing friction (only a small part of the lines 3 is marked in the figure). In addition, the outer surface of the gold standard body 1 is also provided with a drug layer 2 for auxiliary treatment and operation.

[0043] In the existing technology, whether it is stereotactic radiotherapy, stereotactic radiosurgery, or proton therapy, heavy ion therapy, linear accelerator, adaptive radiotherapy, image-guided radiotherapy and helical tomotherapy and other cutting-edge tumor treatment methods, it is required to The higher positioning accuracy of the lesion and the faster dose attenuation outside the target area, if the location of the tumor cannot be deter...

Embodiment 2

[0050] Such as figure 2 As shown, the cobalt-zirconium gold standard implant provided by the present invention includes a gold standard body 1 . Specifically, the gold standard body 1 is made of metal cobalt and zirconium, and its shape is in the shape of a capsule or a drum, and its outer surface is provided with lines 3 for increasing friction. In addition, a cavity is provided inside the body 1 of the gold label, and a hollow through hole 8 is provided on the side wall (only a small part of the hollow through hole 8 is marked in the figure), and a slow-release drug box is built in the cavity. Among them, the drug slow-release box built in the cavity can be filled with high-purity anti-tumor drugs, and the drugs are released through the hollow through holes 8 on the side wall, and work together with the drug layer 2 on the outer wall of the gold standard body 1 to inhibit or even kill the tumor. destroy human tumor cells.

Embodiment 3

[0052] Such as figure 1 , 2 As shown, the cobalt-zirconium gold standard implant provided by the present invention includes a gold standard body 1 . Specifically, the gold standard body 1 is made of metal cobalt and zirconium, and its shape is in the shape of a capsule or a drum, and its outer surface is provided with lines 3 for increasing friction. In addition, the outer surface of the gold standard body 1 is also provided with a drug layer 2 for auxiliary treatment and operation.

[0053] Wherein, the lines 3 (only a small part of the lines 3 are marked in the figure) are cross-shaped, T-shaped and / or V-shaped. In this embodiment, the cross-shaped, T-shaped and / or V-shaped lines 3 are more tightly connected to the fibrous tissues in the human body, and are less likely to slip after being fixed.

Abstract

The invention provides a cobalt-zirconium gold marker implant, and relates to the technical field of implanted medical apparatuses. The cobalt-zirconium gold marker implant comprises a gold marker main body, wherein the gold marker main body is made from metallic cobalt and zirconium; the gold marker main body is represented in a capsule-shaped or drum-shaped form, and lines, by which friction is increased, are arranged on the outer surface of the gold marker main body; and a drug layer is additionally arranged on the outer surface of the gold marker main body. Before a tumor treatment operation, the cobalt-zirconium gold marker implant is implanted into a focus or surrounding tissues thereof; with the design of the lines, friction force between the cobalt-zirconium gold marker implant and human tissues is increased, and since the metallic cobalt and zirconium can shelter X light, the cobalt-zirconium gold marker implant is helpful for medical personnel to accurately track tumor locations in a process of implementing radiotherapy, so that purposes of rapid location and precise treatment are achieved; meanwhile, high-purity drug molecules, which are released from the drug layer, are directly absorbed by the focus so as to take an adjuvant therapy effect to inhibit or kill tumor cells and to improve operating and therapeutic effects. On this basis, the invention also provides a gold marker implantation apparatus.

Description

technical field [0001] The invention relates to the technical field of implantable medical devices, in particular to a cobalt-zirconium gold standard implant and a gold standard implant device. Background technique [0002] Today's tumor treatment methods include five means: surgical treatment, radiotherapy, chemotherapy, traditional Chinese medicine and biological immunotherapy. Among them, radiation therapy, also abbreviated as radiotherapy, is a local treatment method. Although it has only a few decades of history, it has developed rapidly. [0003] With the help of the development of CT imaging technology and computer technology, radiotherapy technology has developed from two-dimensional radiotherapy to three-dimensional radiotherapy and four-dimensional radiotherapy technology, and radiotherapy dose allocation has also developed from point dose to volume dose allocation, and dose intensity modulation in volume dose allocation. For example, stereotactic radiotherapy (SR...
