Description
Technical Field
The utility model belongs to the technical field of medical equipment, and particularly relates to a palate injection and puncture needle for clinical use.
Background
Palate injection and puncture are common treatments applied to oral and maxillofacial surgery, and in clinical application, medical staff use an injector to inject medicine into a corresponding position of a human body jaw.
The injection needle in the prior art is a straight needle, and when local medicine injection treatment is performed on the oral mucosa fibrosis fibrous scar of the palate part, the soft palate part is thin in structure, so that the soft palate part is easy to puncture by the injection of the straight needle, the medicine is injected into the nasal cavity, and the medicine cannot be injected into the soft palate; when puncture diagnosis and local drug injection treatment are carried out on hard and soft palate vascular and lymphangioma diseases occurring in the palate, because the soft palate structure is thin, the soft palate is easy to puncture by straight needle injection, so that bleeding of the palatine hemangioma is difficult to stop bleeding, and if the drug is injected, the drug is easy to inject into the nasal cavity and cannot be injected into the soft palate; in the puncture diagnosis of a tumor or the like occurring in a palate, a straight needle injection is likely to puncture the soft palate and enter a nasal cavity because of a thin structure of the soft palate, and cannot puncture and suck a living tissue from which a tumor lesion is obtained.
Therefore, the injection needle of the prior art is inconvenient for injecting all the medicine into the pathological change part of the palate and the pathological change part of the hemangioma of the palate, and is inconvenient for making the needle enter the pathological change part and puncturing and sucking the living tissue sample by the swollen mass of the palate, which is hard and soft.
