<P>PROBLEM TO BE SOLVED: To provide an injection needle for an endoscope capable of reducing the burden of an operator and relieving the pain of a patient by easily changing the direction of the needle tip inside the body cavity and easily selecting the direction of the needle tip for the secure puncture in a tissue inside the body cavity. <P>SOLUTION: The injection needle 1 for the endoscope has an outer tube 4 and an inner tube 5 which can be relatively moved back and forth in the longitudinal direction, and a needle body 12 is attached to the distal end of the inner tube 5. The needle body 12 is projected or retreated from the distal end of the outer tube 4 by the relative back-and-forth movement of the outer tube 4 and the inner tube 5, and the direction of the needle tip 14 of the needle body 12 is changed by rotating the needle body 12. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
