Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a conjoined gold label and a gold label implantation device. Background Art

[0002] Modern radiotherapy technology continues to advance and has entered the era of image-guided precision radiotherapy. Stereotactic Body Radiation Therapy (SBRT) is an important component of modern radiotherapy, which can achieve the effect of ablating tumors, with efficacy comparable to that of surgery. SBRT is characterized by a large single radiotherapy dose and a small number of times, but as the single dose increases, higher requirements are placed on the accuracy of radiotherapy. Gold label implantation is an effective solution. Before radiotherapy, multiple gold labels are implanted in or around the tumor. During radiotherapy, gold label tracking can be used to simulate tumor movement, achieving the purpose of precise radiotherapy and reducing radiotherapy damage to surrounding normal tissues.

[0003] Generally speaking, the spacing between gold markers needs to be relatively uniform and at an appropriate distance to ensure the accuracy and effectiveness of treatment. In CyberKnife treatment, there are usually certain requirements for the spacing between gold markers, preferably about 2 cm. Too small a spacing between gold markers may lead to inaccurate positioning of the gold markers, affecting the formulation and implementation of the treatment plan. For example, if the gold markers are too dense, the CyberKnife tracking system may have difficulty accurately distinguishing each gold marker, resulting in errors. Excessive spacing between gold markers may not fully cover the tumor area, resulting in some tumor tissue not being effectively treated. For example, when treating irregularly shaped tumors, unreasonable spacing between gold markers may prevent the CyberKnife from accurately targeting the edge of the tumor.

[0004] In the existing technology, the process of implanting gold labels is generally a single implantation, that is, first implanting a gold label, manually withdrawing the needle 2 cm, and then implanting the next gold label. The operation efficiency is low, and during the needle withdrawal, due to tissue traction and operation errors, the needle withdrawal distance is likely to be inconsistent with the expected distance, making the distance between the two gold labels uncontrollable, affecting the quality of gold label implantation. Utility Model Content
