“…A large number of researchers have conducted theoretical and experimental analyses on the interaction between the needle and the soft tissue during needle puncture [137][138][139][140][141][142][143][144][145]. Okamura et al [146] proposed an empirical puncture force model, which divided the puncture force into three parts, including stiffness force, friction force, cutting force.…”

Numerous medical devices have been applied for the treatment or alleviation of various diseases. Tribological issues widely exist in those medical devices and play vital roles in determining their performance and service life. In this review, the bio-tribological issues involved in commonly used medical devices are identified, including artificial joints, fracture fixation devices, skin-related devices, dental restoration devices, cardiovascular devices, and surgical instruments. The current understanding of the bio-tribological behavior and mechanism involved in those devices is summarized. Recent advances in the improvement of tribological properties are examined. Challenges and future developments for the prospective of bio-tribological performance are highlighted.

“…Due to the lack of sufficient image guidance and to overcome the effect of superimposed friction forces during insertion, additional sensors or miniaturized imaging probes can be embedded in needles to measure tissue properties directly at the needle tip. For example, an estimation of the tip forces can be achieved by fiber Bragg gratings [14] or Fabry-Pérot interferometry [15]. Alternatively, optical fibers can be embedded to enable optical reflectance spectroscopy [16], Raman spectroscopy [17], or OCT imaging of the interact-ing tissue directly at the needle tip.…”

Soft tissue deformation and ruptures complicate needle placement. However, ruptures at tissue interfaces also contain information which helps physicians to navigate through different layers. This navigation task can be challenging, whenever ultrasound (US) image guidance is hard to align and externally sensed forces are superimposed by friction. Methods: We propose an experimental setup for reproducible needle insertions, applying optical coherence tomography (OCT) directly at the needle tip as well as external US and force measurements. Processing the complex OCT data is challenging as the penetration depth is limited and the data can be difficult to interpret. Using a machine learning approach, we show that ruptures can be detected in the complex OCT data without additional external guidance or measurements after training with multi-modal ground-truth from US and force. Results: We can detect ruptures with accuracies of 0.94 and 0.91 on homogeneous and inhomogeneous phantoms, respectively, and 0.71 for ex-situ tissues. Conclusion: We propose an experimental setup and deep learning based rupture detection for the complex OCT data in front of the needle tip, even in deeper tissue structures without the need for US or force sensor guiding. Significance: This study promises a suitable approach to complement a robust robotic needle placement.
