Abstract

The invention relates to a shallow-cavity titanium marking device which comprises a titanium feeding mechanism, a pricking pin and a catapulting mechanism. A catapulting position is arranged between the pricking pin and the catapulting mechanism, a titanium outlet of the titanium feeding mechanism is arranged at the catapulting position and used for delivering titanium particles to the catapulting position, the pricking pin is provided with a guiding hole communicated with the catapulting position and used for pricking into the edge of the lesion zone of a human body shallow cavity and guiding and ejecting the titanium particles catapulted by the catapulting mechanism into the human body tissue along the guiding hole. The titanium particles injected into the human body tissue can be stably and harmless retained in a human body, can be used for a tumor zone for multiple times, the tumor zone is clearly and accurately positioned after CT scanning, a treatment effect is observed during treatment, and tumor bed change is observed and the possibility of tumor recurrence is found in time during reexamination.

Description

technical field [0001] The invention relates to a titanium marking device for a human body cavity, in particular to a titanium marking device for a shallow cavity. Background technique [0002] The human body cavity, especially shallow cavities such as the mouth, nasal cavity, vagina, and cervix, are directly connected to the outside world. When a tumor occurs, the tumor boundary can be determined by naked eyes and hands, or the lower boundary can be determined by placing iodine gauze before the operation. Iodine gauze can be visualized on CT to mark the lower boundary. However, there are disadvantages in this method: iodine gauze development affects the accuracy of radiotherapy dose distribution; iodine gauze is a one-time mark, which is not reproducible and cannot be stored in the human body for a long time; insufficient. [0003] In the prior art, X-ray contrast agent is usually injected at the lesion, and then CT scanning is performed for positioning. However, the con...
