“…The medical needles are manufactured collectively under stringent quality control and have uniform shape and size. Therefore the mechanical characteristics during puncture are expected to be uniform (LEHTINEN and OKSALA, 1979;LEHTINEN, 1983;vON FRAUNHOFER et al, 1988). Thus we believe that the peak form of puncture force depends only on the strength and tension of the skin and blood vessel.…”

Although blood sampling is frequently performed, a system to take blood samples automatically has not yet been developed. In the paper, as a first step towards automatic blood sampling, an examination of an automatic method for puncturing blood vessels is described. The force waveforms produced by puncturing rabbit ear veins were measured. A characteristic peak, possibly associated with the needle piercing the vessel wall, was observed in each waveform of ten successful cases of 14 trials. An algorithm that allowed the detection of this peak was developed, and parameters of a filter to improve the accuracy of the algorithm were determined. Using this algorithm, automatic needle punctures were performed in a rabbit ear vein and then were simulated using the data derived from manual needle puncture on four other rabbits. The results gave 30 fully successful cases of 33 trials of needle puncture and showed that measurement of the puncture force may be important for automatic needle puncture of blood vessels.

“…Typically, these needles are referred to as MR compatible. However, these low-susceptibility materials are a significant compromise for biopsy, as they cannot be ground as sharply as stainless-steel, resulting in a poor cutting performance and sample quality [5, 6].…”

2DMSI is promising for both needle tracking and artifact-reduced imaging of biopsy needles for a more precise needle localization. 2DMSI may be particularly promising for needles inducing large distortions or for targeting of small lesions. In addition, it may enable the use of needle materials with higher susceptibility and potentially better sampling performance.

“…The demands made on the suture needles used in CABG procedures have increased in a manner consistent with those made on the skills of the surgeon. Penetration performance with minimal tissue trauma, increased needle strength and stiffness to resist bending or breaking in difficult tissue, and needles sized appropriately for the very small diameter vessels have continued to gain in importance 4–8. Since the early 1970's, there have been steady and significant improvements in the design, manufacturing processes, and alloys used for surgical needles, providing continuous enhancement of these performance characteristics.…”

Before 1970, carbon steel needles, nickel-plated to provide corrosion resistance, were the most common.…”

Tungsten‐rhenium suture needles with improved properties for coronary artery bypass graft surgery

2010

Suture needles are essential instruments for performing blood vessel anastomosis in coronary artery bypass graft (CABG) surgeries. Exceptional needle performance is needed now as never before because of the increasing prevalence of elderly patients with advanced stages of coronary disease and calcified tissue. The various properties that affect the performance of suture needles used in CABG surgery are reviewed and recent progress towards improving needle performance through the use of tungsten-rhenium alloys and novel lubricous needle coatings is presented. Substantial enhancement of properties beyond those exhibited by commercially available stainless steel suture needles has been made, including an approximate 40% increase in strength, 100% increase in stiffness, and superior multiple pass penetration performance in both synthetic rubber media and human cadaver carotid arteries (p < 0.01).
