Intimacy medical needle designed for nerve stimulation through soft tissue and microadhesiolysis of adhered soft tissue and medical instrument using the same

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...

AI Technical Summary

Problems solved by technology

Therefore when performing epidural anesthesia, there will be a high risk of dural and arachnoid laceration by the sharp tissue puncture point of the needle and a corresponding risk of CSF leakage, which may lead to phenomena such as dural puncture Severe complications such as posterior headaches

In addition, when the existing medical needle is inserted into the dura mater to extract cerebrospinal fluid, the sharp cutting edge and tissue puncture point of the needle may damage the spinal cord and nerve roots surrounded by the dura mater, resulting in conditions such as body paralysis and Serious problems such as neuropathy

[0007] In addition, when the existing medical needle enters the body, it will leave many lacerations in the tissue because of its sharp edge to split the tissue
