Radiotherapy positioning gold label recovery device and use method thereof

Abstract

The invention discloses a radiotherapy positioning gold label recovery device and a use method thereof. The radiotherapy positioning gold label recovery device comprises a positioning gold label and recovery claw forceps, and is characterized in that the positioning gold label comprises a gold label body and an elastic fixing structure; the elastic fixing structure comprises a fixing section, an extension section and a spiral section which are connected in sequence; the fixing section is embedded in the gold label body, so that the fixing section and the gold label body are tightly connected,and relative sliding or displacement between the fixing section and the gold label body is avoided; a small magnetic ball is arranged at the end, far away from the extension section, of the gold labelbody; the recovery claw forceps comprise an operating handle; the tail part of the operating handle is connected with an outer sheath tube of a hollow structure; and a zipper used for driving the claw forceps to be opened and closed is movably linked to the interior of the outer sheath tube. According to the invention, effective fixation in the lung trachea is achieved through the gold label structure with the spiral section, and gold label displacement caused by breathing is effectively avoided; and the gold label can be conveniently recovered through the cooperation of a claw forceps body in the recovery claw forceps and the small magnetic ball.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a radiation therapy positioning gold standard recovery device and a method for using the same. Background technique [0002] With the development of radiotherapy technology and the development of precision radiotherapy technology, the efficacy of radiotherapy has been improved and the side effects have been reduced. During Cyberknife treatment, it can track the location of the tumor and achieve precise treatment. The gold standard is usually made of pure gold particles with a length of 3-5 mm and a diameter of 0.70-0.80 mm. The tumor position is obtained in real time through digital images, and the treatment rays are guided for automatic correction. The existing gold label designs are all based on the shape of a cylinder. When the gold label of this design is implanted in the human body, the gold label will be lost or the gold label will be displaced due to the patient's...

AI Technical Summary

Problems solved by technology

In addition, the gold label is also susceptible to displacement due to the influence of breathing, body position, etc. The gold label is far away from the tumor target area, and there is a 4%-20% chance of failure in positioning, and the puncture gold label is implanted in the patient's body for a long time after radiotherapy. and cannot be recycled

At present, the gold label has not obtained the CFDA Class III registration certificate, which makes it impossible to carry out clinical work. This is the bottleneck of the development of CyberKnife gold label tracking technology
