Over millions of years of evolution, species in nature have gradually adopted biostructures. These structures have specific mechanical, hydrodynamic, optical, and electrical properties, which provide humans with valuable abilities to design and fabricate high-performance components and devices. However, traditional fabrication technologies cannot accurately reproduce or imitate the complicated and exquisite bioinspired structures, which restrict the development and application of biomimetic study. Due to the emergence and development of 3D printing technologies, more bioinspired structures can now be designed and fabricated. Recent progress in the 3D printing of structures inspired by species in nature, such as springtails, filefish, abalone shell, conch shell, wheat awn, plant stem, and wood, are reviewed in this paper, which also discusses current challenges and potential future developments in 3D printing for bioinspired structures.

“…Inspired by these features, an early study demonstrated the feasibility of harpoon-shape notches in a silicon needle tip for insertion into a soft tissue phantom 27 . In experiments of insertion into the tissue-mimicking phantom 1 and the ex-vivo tissue 28 , the notched needle tips exhibited lower insertion forces when compared to the needle without notches. The insertion of a needle device with multiple incrementally moving needle components without the harpoon-shape notches was studied and showed the independent benefit of incremental motion to reduce the tissue phantom displacement during insertion 29 and allow deep insertion without buckling 30,31 .…”

Mosquito proboscis-inspired needle insertion to reduce tissue deformation and organ displacement

This study investigates mosquito proboscis-inspired (MPI) insertion applied to the clinically used biopsy needle to reduce tissue deformation and organ displacement. Advanced medical imagining has enabled early-stage identification of cancerous lesions that require needle biopsy for minimally invasive tissue sampling and pathological analysis. Accurate cancer diagnosis depends on the accuracy of needle deployment to the targeted cancerous lesion site. However, currently available needle delivery systems deform and move soft tissue and organs, leading to a non-diagnostic biopsy or undersampling of the target. Two features inspired by the mosquito proboscis were adopted for MPI insertion in prostate biopsy: (1) the harpoon-shape notches at the needle tip and (2) reciprocating needle-cannula motions for incremental insertion. the local tissue deformation and global prostate displacement during the MPI vs. traditional direct insertions were quantified by optically tracking the displacement of particle-embedded tissue-mimicking phantoms. Results show that the MPI needle insertion reduced both local tissue deformation and global prostate displacement because of the opposite needle-cannula motions and notches which stabilized and reduced the tissue deformation during insertion. Findings provide proof of concept for MPI insertion in the clinical biopsy procedures as well as insights of needle-tissue interaction for future biopsy technology development. Mosquito proboscis is an ideal needle device which minimizes the deformation and displacement of surrounding tissue during insertion for accurate guidance to targeted vessels. The proboscis has a hollow labrum (about 25 μm wide) and two maxillae (about 15 μm wide) with harpoon-shape notches on the side 1 as shown in Fig. 1a. During insertion, the proboscis advances incrementally with vibratory relative displacements of the labrum and maxillae for reciprocating tissue penetration 2,3. A study proposed the mechanism of proboscis insertion 1 as illustrated in Fig. 1b. In Step 1, the left maxilla moves forward into the tissue while the labrum retracts a shorter distance in the opposite direction. In Step 2, the labrum moves forward while the maxillae retract utilizing their notches to anchor the surrounding tissue. The forward motion of the right maxilla and backward motion of the labrum in Step 3 mirror the motions in Step 1. In Step 4, movements of both maxillae and the labrum in Step 2 are repeated. After moving the left maxilla forward and the labrum backward in Step 5, the relative positions of the maxillae and labrum are the same as in Step 1. At this state, the proboscis has moved forward by a distance marked by the wide arrow in Fig. 1b. By repeating the above steps, the proboscis incrementally advances with vibratory motions. The vibratory reciprocating motions of mosquito proboscis have been found to reduce insertion force and resultant tissue deformation 3,4. The harpoon-shape notches of the maxillae may further provide critical support and anchoring to reduce tissu...

The robot-assisted insertion surgery plays a crucial role in biopsy and therapy. This study focuses on determining the optimum puncture pattern for robot-assisted insertion, aiming at the matching problem of needle insertion parameters, thereby to reduce the pain for patients and to improve the reachability to the lesion point. First, a 6-degrees of freedom (DOFs) Computed Tomography (CT)-guided surgical robotic system for minimally invasive percutaneous lung is developed and used to perform puncture experiments. The effects of four main insertion factors on the robotic puncture are verified by designing the orthogonal test, where the inserting object is the artificial skin-like specimen with high transparent property and a digital image processing method is used to analyze the needle tip deflection. Next, the various phases of puncture process are divided and analyzed in detail in view of the tissue deformation and puncture force. Then, short discussion on the comparison of puncture force with different effect factors for the same beveled needle is presented. The same pattern can be observed for all of the cases. Finally, based on the experimental data, the formulations of the puncture force and needle deflection which depends on Gauge size, insertion velocity, insertion angle, and insertion depth are developed using the multiple regression method, which can be used to get an optimum puncture pattern under the constrains of minimum peak force and minimum needle tip deflection. The developed models have the effectiveness and applicability on determining the optimum puncture pattern for one puncture event, and which can also provide insights useful for the setting of insertion parameters in clinical practice.

Insertion mechanics of bioinspired needles into soft tissues

Abstract: The reduction in the insertion force is due to the decrease in the friction force of the bioinspired needle with the bovine tissues, and its results are consistent with our previous results.
