Abstract

A medical needle comprises a main body extending from a proximal end to a distal end, and a tip portion formed at the distal end of the body. The tip portion has a first inclined region, the cross-sectional area of which decreases toward the distal end and has a pair of surfaces inclined with an angle of 15 DEG to 20 DEG . The tip portion has a second inclined region extending from the first inclined region, the cross- sectional area of which decreases toward the distal end and has a pair of surfaces inclined with an angle of 30 DEG to 45 DEG . A tip is formed at the point of juncture of the pair of surfaces of the second inclined region. Tapered portions are formed on both sides of the first inclined region. Each tapered portion is inclined at an angle of 5 DEG to 15 DEG . Curved portions are formed at the points of juncture of the tip and the ta ered ortions.

Description

technical field [0001] The present invention relates generally to medical needles and, more particularly, to a medical needle for insertion into a patient's painful area or site for stimulation and / or injection therapy of certain painful or disabling areas or sites. Needle. Background technique [0002] Chronic pain has become a health problem that has grown dramatically in recent years. Studies to date have shown that stimulation therapy or injection therapy targeting painful areas or sites is one of the effective ways to manage or control chronic pain. [0003] US Patent No. 2,409,979 discloses a therapeutic needle for treating musculoskeletal pain, which will be described below with reference to FIGS. 9 and 10 . [0004] As shown in FIGS. 9 and 10 , such a needle comprises a body 10 of circular cross-section having a bore 11 terminating in a discharge end or outlet delimited by the edge of the wall of the body 10 . The body 10 is curved to have a curved surface 15 exte...
