Abstract

The invention belongs to the technical field of medical treatment, and particularly relates to a gastrointestinal tract malignant tumor target tracking device which is of a capsule structure, the capsule structure comprises a capsule shell and content, and the capsule shell is prepared from gelatin, purified water, dilute acid, a plasticizer and chitosan; the structure of the content is as follows: the content comprises a mother nucleus, a plurality of branch buds are dispersed around the periphery of the mother nucleus, the plurality of branch buds are distributed in a radial shape or a star shape, and the end part, far away from the mother nucleus, of each branch bud is provided with a medicine carrying ball; the parent nucleus and the branch buds are prepared from gelatin, purified water and a plasticizer; the drug-loaded ball is prepared from gelatin, purified water, a plasticizer and an anti-tumor drug; the capsule shell or the medicine carrying ball is provided with a tracking mark used for identifying the position of a malignant tumor. The device disclosed by the invention can be used for carrying out target tracking on gastrointestinal tumors.

Description

technical field [0001] The invention belongs to the field of medical technology, and in particular relates to a device for tracking the target of gastrointestinal malignant tumors. Background technique [0002] Malignant tumors are commonly referred to as cancers, which have abnormal cell differentiation and proliferation, out-of-control growth, and biological characteristics such as invasion and metastasis. Exposure, environmental pollution, genetics and other factors are related. The clinical manifestations of malignant tumors can be lumps, pain, ulcers, bleeding, etc. There are local symptoms, systemic symptoms, and even tumor metastasis. [0003] The examination of malignant tumors includes genetic testing, imaging examination, tumor marker detection, pathological tissue examination and other methods. After comprehensive evaluation of various examination results, the diagnosis result is given. [0004] The treatment of malignant tumors includes surgical treatment (rese...
