Surgeons insert approximately 3000 hair implants in a single hair restoration surgery, and the needle shape critically affects surgical performance including surgical time, survival rate, and the surgeon s fatigue. There are several experimental studies on the relationship between needle shape and performance; however, there are no studies on hair implant needles, which are different from other medical needles as they have a comparatively short bevel. This study compared several hair implant needles to determine the relationship between needle shape and insertion force. Eight hair implant needles with the same diameter were collected, and their geometrical data were visually measured. The insertion force and total work of each needle were measured using custom-made force measurement equipment; the results were statistically compared, and their correlation was analyzed. Moreover, a qualitative comparison was made. The needle insertion force ranged from 1.30 to 2.97 N, and the total work ranged from 8.15 to 10.97 mJ. The primary bevel and acute angles showed a moderate positive correlation with the total work. A longer point length, smaller primary bevel, and acute angle decrease the total work of hair implant needles. As per the results of the qualitative comparison, we found that the surgeons can identify the differences in needle insertion force among various hair implant needles, and their grading was consistent with the grading according to the total work of needle insertion.

“…The factor affecting needle geometry and insertion force is β. Jushiddi et al [14] reported that β ranged from 18 to 27 , prevalently in trocar or biopsy needles, but β of the hair implant needles used in our study ranged from approximately 25 to 35 . Jiang et al [15] reported that F cut was low when β ranged between 10 and 30 .…”

Steerable needles have been widely researched in recent years, and they have multiple potential roles in the medical area. The flexibility and capability of avoiding obstacles allow the steerable needles to be applied in the biopsy, drug delivery and other medical applications that require a high degree of freedom and control accuracy. Radius of Curvature (ROC) of the needle while inserting in the soft tissue is an important parameter for evaluation of the efficacy, and steerability of these flexible needles. For our Fracture-directed Stylet-and-Tube Steerable Needles, it is important to find a relationship among the resultant insertion ROC, pre-set wire shape and the Young's Modulus of soft tissue to characterize this class of steerable needles. In this paper, an approach is provided for obtaining resultant ROC using stylet and tissue's mechanical properties. A finite element analysis is also conducted to support the reliability of the model. This work sets the foundation for other researchers to predict the insertion ROC based on the mechanical properties of the needle, and the soft tissue that is being inserted.

“…Meanwhile, the length of the introducer was 3.5inch (Derby et al, 2016). The 27° bevel angle of the introducer tip used to decrease the deflection result from inserting the needle into the skin tissue (Jushiddi et al, 2019). Stainless steel alloys have been used in the orthopedic implant (Jujur et al, 2015;Saini et al, 2015) and medical equipment (Tsen and Hepner, 2006;Bakar Sulong et al, 2016).…”

Stem cell studies have progressed significantly in the last decades. Similarly, stem cell therapies have also been applied in clinical settings, includingthe spine. However, stem cells' delivery to the spinal region requires delicate procedures, demanding reliable introducers in addition to the surgeons' psychomotor skills. The introducer is a tubular sleeve to guide a syringe needle to deliver and draw fluids into and from the body, respectively. To date, there is no introducer dedicated to spinal stem cell deliveries. Our group proposed a dedicated introducer for spinal stem cell therapies, which consists of a needle and a hub (a base part of an introducer for gripping and handling). We focused onthe weighting property method (WPM) to select four polymer candidates for the hub:polystyrene, polycarbonate, polypropylene, and polyethylene. Prior to WPM, the mechanical integrity of the hub candidates was analyzed using the finite element method to determine the von Mises Stress (vMS) values. Accordingly, the vMS for each case and the material was compared with the respective tensile strength (TS), thereby vMS:TS ratio (MTR).MTR was included as one of the properties in WPM, in addition to prices, critical radiation doses, hardness, water absorption, and isopropyl alcohol resistance.According to the WPM calculation, polycarbonate received the highest score, thereby recommended for further introducer fabrications.
