本实用新型涉及一种医疗器械，尤其是一种医用注射针。The utility model relates to a medical device, in particular to a medical injection needle.
背景技术Background technique
现有针对人体内病变器官注射治疗，不开刀下大都采用带软管的注射针注射治疗。该种治疗方法在胃镜下注射较为常用，常规的方法为在胃镜窥视下，在胃镜的活检管开口处插入带有软管的注射器注射治疗对于胃癌等疾病有较好的治疗效果。现有技术注射针的针头是固定设计的，对于不是很深或很深的病变组织，采用这种注射针的针头势必对治疗效果会有所影响。Existing injection treatment for diseased organs in the human body, mostly adopts the injection needle injection treatment with flexible tube under not operating the knife. This treatment method is more commonly used for injection under gastroscope. The conventional method is to insert a syringe with a soft tube at the opening of the biopsy tube of gastroscope under the peep of gastroscope for injection treatment, which has a good therapeutic effect on diseases such as gastric cancer. The needle head of the prior art injection needle is designed fixedly, and for the diseased tissue that is not very deep or very deep, the needle head of this injection needle will definitely affect the therapeutic effect.
