Description

A neck lymph node dissection retractor

technical field

The invention relates to a lymph node dissection retractor, in particular to a neck lymph node dissection retractor.

Background technique

The cervical lymph is located in the submental triangle, receives the lymph from the chin, the floor of the mouth, and the tip of the tongue, and is injected into the submandibular lymph nodes and the internal jugular digastric lymph nodes. Lymphatic tissue in the neck comes from lymphatic drainage from the nose, sinuses, pharynx, larynx, mouth and face. Lymph node is an important immune organ of the body, and it is the place where the immune response is stimulated by antigen, and it has the functions of filtration, proliferation and immunity. The normal human superficial lymph nodes are very small, less than 0.5cm in diameter, with smooth and soft surface, no adhesion to the surrounding tissue, and no tenderness.
