AB - The mobility of soft tissue can cause inaccurate needle insertions. Particularly in steering applications that employ thin and flexible needles, l arge deviationscan occur between preoperative images of the patient, from which a procedure is planned, and the intraoperative scene, where a procedure is executed. Whereas many approaches for reducing tissue motion focus on external constraining or manipulation, little attention has been paid to the way the needle is inserted and actuated within soft tissue. Using our biologically inspiredsteerable needle, we present a methodof reducing the disruptivenessof insertionsby mimicking the burrowing mechanism of ovipositing wasps. Internal displacements and strains in three dimensionswithin a soft tissue phantom are measured at the needle interface,using ascanninglaser basedimage correlation technique.Compared to a conventional insertion methodwith an equally sized needle,overall displacementsand strainsin the needle vicinity arereduced by 30% and 41%, respectively.The results show that, for a given net speed,needle insertion can be made significantly less disruptive with respect to its surroundings by employing our biologically inspired solution. This will have significant impact on both the safety and targeting accuracy of percutaneous interventions along both straight and curved trajectories
