“…In addition, since the diameter of commercial needles is non-linear in gauge representation and the wall thickness of needles is different for product companies, the results in the reports cannot be compared quantitatively. Brett [5] measured the axial component of the needle force to detect the epidural puncture. However, he didn't investigate the transverse force, which has a strong effect on the needle deflection.…”

Abstract.A force-deflection model of needle penetration is proposed and evaluated experimentally. The force at the fixed end of the needle and the needle deflection were measured using a force sensor and a bi-plane X-ray imaging system, and the model was evaluated with the data. We define a physical quantity o, which we call infinitesimal force per length, analogous to traction (force per surface area). The model predicts 61 to be constant over the length of the inserted portion of the needle. However the results indicate that this assumption does not fully account for the real deflection. It is strongly suggested that there is an additional degree of freedom: a moment or a rotational force acting on the needle.

“…Some of them monitor the insertion with a force sensor instead of imaging [3,4]. Force sensing has no spatial information, though it has advantages over imaging in the view of its ability to sense the dynamic and local properties of tissue [9] and its great cost effectiveness.…”

Abstract.A force sensor based method to detect the instant of needle puncture to the layers of tissues is proposed. A set of needle and sheath attached to a pair of coaxial force sensors was used to separately measure the cutting force at the needle tip and the sidewall friction. Change of the force profile was observed and marked at the instant of the puncture, and robustly eliminated artifacts caused by body motion such as the respiratory or cardiac motion. The agreement between the subjective feeling of a skilled surgeon and the sensor was good. In several cases the sensor detected the puncture even when the surgeon could not clearly identify it. It was suggested that the sensor is potentially more sensitive than skilled professionals.

“…In the operation of invasive surgical tools, tissue information at the needle tip is critical in order to control the movement of the needle [2]. Since tissue properties can be represented approximately by a spring-damping mechanical model [3], tissue can be identified by measurement of its equivalent mechanical impedance, which is defined as the ratio of the responded force to the displacement exerted on tissue.…”

Study of miscibility and interaction in polyvinyl chloride-polyvinyl acetate blend using ultrasonic technique P V Tabhane, O P Chimankar, R S Shriwas et al. Abstract. For safety improvement purposes, detection of tissue properties at the tip of the needle in real-time is helpful in controlling the movement of the needle in the operation of invasive surgical tools. According to the energy-based force model, the mechanical impedance of tissue can be represented approximately by a spring-damping model. In this study, a vibration-based syringe which adopts piezoelectric elements to vibrate the needle is proposed to identify tissue properties. In principle, by measuring the input electrical impedance of the vibration-based syringe, the mechanical impedance of tissue can be detected indirectly while the syringe exerts a vibration on the tissue. The model of the piezoelectric driven syringe and the procedure for evaluating the electromechanical interaction are given, and the mechanical impedance of tissue is evaluated by simulation. The proposed detection method has potential for applications of identifying tissue properties in epidural punctures and estimation of the degree of ablation in thermal surgery systems.
