INJECTION NEEDLE FOR INJECTING AN INJECTION SOLUTION INTO A JOINTCAVITY AND SYRINGE HAVING THE SAME

摘要

Disclosed is an injection needle for injection into a joint cavity for facilitating depth recognition when injecting an injection into a joint cavity. The injection needle for injection into the joint cavity includes a needle body and a belly button. The needle body includes an end defined as a fluid injection tip. The baebulim portion is formed in the middle portion of the needle body in a baebulrim shape so that the operator can feel the moment when the needle body penetrates into the joint cavity when injecting the joint cavity injection solution. Accordingly, since the joint cavity is slightly thick and elastic, small balls are formed in a part of the outer peripheral surface adjacent to the fluid injection tip, which is the end of the injection needle, so that you can feel the moment of penetrating the joint cavity. It can be useful.
