Injection device for endoscopy

An endoscopic injection apparatus comprising:

• a needle configured to eject an injection solution;
• a pair of holding forceps which surrounds the needle;
• an operation unit configured to hold an injection targeted area using the pair of holding forceps and injects the injection solution when the needle is inserted in a tissue;
• a sensor configured to sense a spread angle of the pair of holding forceps;
• and
• a notification unit configured to display a sensing result of the sensor,
• wherein the operation unit comprises:
• a body with a needle operation button on one end;
• an injection hole for the injection solution which is formed on the body;
• and
• a forceps operation unit configured to operate the pair of holding forceps according to a sliding movement and surround a body exterior,
• wherein the needle operation button is configured to operate only when the spread angle of the pair of holding forceps is within a predetermined angle, wherein the predetermined angle is selected to be a state in which the pair of holding forceps are holding the injection targeted area,
• wherein the endoscopic injection apparatus further comprises:
• a predetermined length of a shaft which is connected with another end of the body and wherein a fixing piece is formed within an inner one end of the shaft and a part of the fixing piece protrudes outside the shaft and the pair of holding forceps is installed in hinged to the fixing piece with an incision unit formed in the middle of the fixing piece;
• and
• a fixing member configured to fix the needle which is formed with a predetermined length and diameter as to be inserted and installed in the shaft,
• wherein the fixing member has at least one side that is formed in a concave shape in a needle direction and a predetermined space is formed between the at least one side of the fixing member and an inner side of the shaft.
