Abstract
The present invention relates to an injection device for endoscopy, and provides: a feature of inserting a needle for endoscopy into a tissue, in a state of holding a body tissue, which is a region to receive an injection, and then injecting an injection solution thereinto; and a feature enabling stanching of the bleeding region if bleeding occurs. That is, tissue is held by holding forceps and a needle is inserted thereinto, corresponding to a series of operations from a state in which the needle is accommodated between the holding forceps for holding the tissue, and then an injection solution is injected into the tissue through the needle. In addition, a bleeding region is stanched by the heat transferred to the holding forceps without using a separate hemostat if bleeding occurs during the operation. According to the present invention, the precise position of an injection target region can be confirmed, and thus the generation of a tissue perforation due to a needle can be prevented, and bleeding can be immediately stanched without using a separate tool if bleeding occurs.
