Technical Field

[0001] The present invention relates to the technical field of tumor injection, and in particular to a multi-angle tumor injector. Background Art

[0002] A tumor injector is a medical device used to inject drugs directly into the tumor site. This device is usually designed for tumor treatment and can accurately control the amount and speed of drug injection to ensure that the drug can effectively act directly on the tumor tissue and minimize damage to healthy tissue.

[0003] Tumors can be found in a variety of tissues and organs throughout the body, and their shape and location vary depending on the type of tumor and how it grows. For example, basal cell carcinomas often grow on parts of the body that are exposed to the sun, especially the face and neck.

[0004] Traditional tumor injections are performed using a syringe. When a syringe is manually held to inject medication into basal cell carcinoma on the face, there are errors in the injection angle and injection speed.

[0005] In summary, the prior art lacks a stable automatic injection technology for basal cell carcinoma of the face. Summary of the invention
