Title: Histological Study of Tissue Damage due to Composite-Coated Needle Insertion
Abstract Reducing the force required during needle insertion is vital to minimize tissue damage in percutaneous procedures. A composite coating of Polydopamine, Polytetrafluoroethylene, and Activated Carbon materials was applied to the needles to address this challenge. The coating reduces needle surface friction, which eventually helps to decrease the insertion force and minimize tissue damage. In this study, measuring the insertion and extraction forces inside a bovine kidney showed that the coated needles decreased the insertion force by 49% and the extraction force by 30%. In addition, a histological analysis was conducted to compare the tissue damage caused by coated and bare needles. The results revealed that coated needles insertion reduced tissue damage by 39.6% compared to bare needles. These findings highlight the potential of this composite coating approach to improve the safety and precision of percutaneous procedures.  more » « less

    Medical interventions require control over surgical needle insertion to minimize tissue damage and target inaccuracies during percutaneous procedures. The composite coating of the needle using Polydopamine (PDA), Polytetrafluoroethylene (PTFE), and Activated Carbon (C) has been used to reduce the damaging needle insertion force. This research aims to further understand the interfacial mechanics of coated needle insertion by studying the forces at the needle and tissue interface and developing an analytical insertion force model through a combined experimental and numerical method. The proposed analytical force model is divided into two components: (1) Friction force on the needle shaft, modeled using a modified Karnopp model that includes an elastic force component; (2) Cutting force on the needle tip, modeled using a constant cutting coefficient for a given tissue and insertion speed. In this work, the analytical model was established by incorporating experiments conducted at a reasonable 35 mm insertion depth in tissues. In a bovine kidney with a 35 mm insertion depth, the insertion force evaluated through experimentation and modeling differed by 6.5% for a bare needle and 17.1% for a coated needle. It is important to note that this difference in the analytical insertion force model is anticipated when dealing with real tissues with a highly complex structured tissue. Prediction of the insertion force could potentially be utilized in robotic needle systems for needle control to improve the success of percutaneous procedures.

    Abstract Soft tissue biopsy is a necessary diagnostic and therapeutic procedure, but traditional biopsy needles can cause harm to the patient, including tissue damage, bleeding, and pain. These can compromise the accuracy of the sample and negatively impact the patient’s well-being. Hence, there has been a growing interest in developing bio-inspired surgical needles that are safer, more effective, and more comfortable for the patient. The scorpion-inspired curved tip needle study focuses on analyzing the mechanics of needle-tissue interaction and creating needles that travel through soft tissue with minimum resistance at the tip. An essential aspect of the study is the mechanics and geometry of the needle tip, which plays a crucial role in its performance. The study incorporates structures of curved scorpion’s stinger to balance between penetration and minimal needle-tissue interaction forces. In this study, various parameters of curved tip geometry are explored to decrease the insertion and extraction forces. Tests are initially performed on brain tissue mimicking medical gelatin with Young’s modulus of 2kPa. It is observed that the insertion force with curved tip needles is decreased by up to 21.7%, and the extraction force is decreased by up to 28.2%. This study shows that a scorpion-inspired tip design can minimize insertion and extraction forces, leading to less tissue damage and deformation. Furthermore, the proposed tip design has great potential to improve surgical needles for more effective minimally invasive percutaneous procedures with various applications such as biopsy, brachytherapy, tumor ablation, and drug delivery to the brain.

    Abstract Active needles obtain more significant tip deflection and improved accuracy over passive needles for percutaneous procedures. However, their ability to navigate through tissues to reach targets depends upon the actuation mechanism, the tip shape, and the surface geometry of the shaft. In this study, we investigate the benefits of changing the surface geometry of the active needle shaft in a) needle tip deflection and b) trajectory tracking during tissue insertion. The modifications in passive needle surface geometry have been proven to reduce friction force, tissue displacement, and tissue damage. This study incorporates the effect of modifying the regular smooth cannula with a mosquito proboscis-inspired design in the active needles. The changes in insertion force, tip deflection, and trajectory tracking control during insertion into a prostate-mimicking phantom are measured. Results show that insertion force is reduced by up to 10.67% in passive bevel-tip needles. In active needles, tip deflection increased by 12.91% at 150mm when the cannula is modified. The bioinspired cannula improved trajectory tracking error in the active needle by 39% while utilizing up to 17.65% lower control duty cycle. Improving tip deflection and tracking control would lead to better patient outcomes and reduced risk of complications during percutaneous procedures.

    Abstract Active needles demonstrate improved accuracy and tip deflection compared to their passive needle counterparts, a crucial advantage in percutaneous procedures. However, the ability of these needles to effectively navigate through tissues is governed by needle-tissue interaction, which depends on the tip shape, the cannula surface geometry, and the needle insertion method. In this research, we evaluated the effect of cannula surface modifications and the application of a vibrational insertion technique on the performance of shape memory alloy (SMA)-actuated active needles. These features were inspired by the mosquito proboscis’ unique design and skin-piercing technique that decreased the needle tissue interaction force, thus enhancing tip deflection and steering accuracy. The bioinspired features, i.e., mosquito-inspired cannula design and vibrational insertion method, in an active needle reduced the insertion force by 26.24% and increased the tip deflection by 37.11% in prostate-mimicking gel. In addition, trajectory tracking error was reduced by 48%, and control effort was reduced by 23.25%, pointing towards improved needle placement accuracy. The research highlights the promising potential of bioinspired SMA-actuated active needles. Better tracking control and increased tip deflection are anticipated, potentially leading to improved patient outcomes and minimized risk of complications during percutaneous procedures.
