摘要
Disclosed is an injection needle for injecting an injection solution into a joint cavity for facilitating recognition of depth when an injection solution is injected into the joint cavity. An injection needle for injection of a joint cavity injection solution includes an injection needle body and a stomach portion. The needle body includes a terminal portion defined as a fluid injection tip. The stomach bulge part is formed in a pear bulge shape in the middle part of the injection needle body so that the operator can feel the moment when the injection needle body penetrates into the joint cavity when the injection solution is injected into the joint cavity. Accordingly, since the joint cavity is slightly thick and elastic, a small ball is formed in a partial area of the outer circumferential surface adjacent to the fluid injection tip, which is the end of the injection needle, so that the feeling of entering the joint cavity can be felt better than when injecting the joint cavity injection solution. It can be useful.
