Deflection of spinal needles by the bevel.
نویسندگان
چکیده
Bevelled spinal needles sizes 22 and 25 gauge were passed through tough meat to assess the influence of bevel orientation on the path of the needle. The needle bent away from the bevel surface by about 1 mm for each centimetre of needle travel through the tissue. With an introducer, the deviation was reduced by a reduction of the distance of unsupported travel. Pencil-point needles were less deviated.

Comparison of Spinal Needle Deflection in a Ballistic Gel Model
BACKGROUND Percutaneous diagnostic and therapeutic procedures are commonly used in the treatment of spinal pain. The success of these procedures depends on the accuracy of needle placement, which is influenced by needle size and shape. OBJECTIVES The purpose of this study is to examine and quantify the deviation of commonly used spinal needles based on needle tip design and gauge, using a bal...
متن کاملEffects of Tip Geometry of Surgical Needles: an Assessment of Force and Deflection
Precise placement and steering of surgical needles is very important for many medical diagnostic and therapeutic procedures. But accurate steering and placement of needles in soft tissue is challenging because of a variety of reasons. In this study we focused on the effects of tip geometry (bevel tip, diamond tip, and conical tip) of brachytherapy needles while inserted in soft material phantom...
متن کاملThe history of spinal needles: getting to the point.
The history of the design of spinal needle tips is discussed, from the first needles used by J. Leonard Corning in 1885 to innovative, modern needle designs that continue to appear on the market. The shape of the needle tip started as a cutting bevel and developed into the atraumatic tip and the pencil-point tip in current common use. Innovative designs such as the stylet-tipped needle and the ...
متن کاملDura-arachnoid lesions produced by 22 gauge Quincke spinal needles during a lumbar puncture.
AIMS The dural and arachnoid hole caused by lumbar puncture needles is a determining factor in triggering headaches. The aim of this study is to assess the dimensions and morphological features of the dura mater and arachnoids when they are punctured by a 22 gauge Quincke needle having its bevel either in the parallel or in the transverse position. METHODS Fifty punctures were made with 22 ga...
متن کاملMacroscopic and microscopic observations of needle insertion into gels.
Needle insertion into soft tissue is one of the most common medical interventions. This study provides macroscopic and microscopic observations of needle-gel interactions. A gelatin mixture is used as a soft-tissue simulant. For the macroscopic studies, system parameters, such as insertion velocity, needle diameter, gel elasticity, needle tip shape (including bevel angle) and insertion motion p...
