“…Note that the upper limit of force is set to 6 N, because the adopted haptic device can generate only 8.5 N as a peak value. Also, it should be noticed that the device has a limited ability to simulate stiff bones, ligamentum flavum, and some membranes, due to the limited peak force of 8.5 N. 5 Hence, for more realistic force feedback, the system needs a haptic device providing a higher peak force of about 20 N. 16 Correction force to simulate tissue constraint. In an actual needle biopsy, motion of the needle is constrained after insertion into body tissues.…”

“…Extensive training is essential to ensure reliable and effective operations, and a novel simulator has become necessary. To this end, Singh and Popa measured force from the needle during such a biopsy and tried to generate similar force reflection in a needle biopsy simulation, 5,6 while Cleary and Greco developed a 2D spine needle biopsy simulator using a haptic device. 7 In this article, we introduce a 3D spine needle biopsy simulator (SNBS) that provides realistic visual and force feedback to a trainee in a PC environment.…”

BackgroundLumbar puncture is an essential medical procedure whose objective is to obtain cerebrospinal fluid. Lumbar puncture is considered a complex procedure, mainly for novice residents who suffer from stress and low confidence, which may result in harm to the patient.MethodsThe LPVirSim, has been developed in four stages: i) requirements analysis through user‐centred design; ii) prototyping of the virtual environment and the haptic component; iii) preliminary tests with Ph.D. students and physicians using two haptic devices (Omega.7 and Sigma.7); iv) a user study where physicians evaluated the usability and user experience.ResultsThe LPVirSim integrates non‐technical skills and the possibility of representing different patients for training. Usability increased from 61.76 to 68.75 in the preliminary tests to 71.43 in the user study.ConclusionsAll the results showed good usability and demonstrated that the simulator arouses interest and realistically represents a Lumbar puncture, through the force and visual feedback.

“…We refer to some related studies using various approaches to detect the subarachnoid space. Several methods use tactile devices that monitor the force feedback and its change or derivative as the needle tip penetrates through different soft tissue layers (Singh et al, 1994 ; Ambastha et al, 2016 ; Li et al, 2021 ; Wang and Li, 2022 ). A different CSF detection method proposed by Sievänen et al ( 2021 ) uses a bio-impedance needle, which measures the electrical impedance of the tissues as a function of time by applying and sensing an alternating current.…”

IntroductionLumbar puncture is an important medical procedure for various diagnostics and therapies, but it can be hazardous due to individual variances in subcutaneous soft tissue, especially in the elderly and obese. Our research describes a novel robot-assisted puncture system that automatically controls and maintains the probe at the target tissue layer through a process of tissue recognition.MethodsThe system comprises a robotic system and a master computer. The robotic system is constructed based on a probe consisting of a pair of concentric electrodes. From the probe, impedance spectroscopy measures bio-impedance signals and transforms them into spectra that are communicated to the master computer. The master computer uses a Bayesian neural network to classify the bio-impedance spectra as corresponding to different soft tissues. By feeding the bio-impedance spectra of unknown tissues into the Bayesian neural network, we can determine their categories. Based on the recognition results, the master computer controls the motion of the robotic system.ResultsThe proposed system is demonstrated on a realistic phantom made of ex vivo tissues to simulate the spinal environment. The findings indicate that the technology has the potential to increase the precision and security of lumbar punctures and associated procedures.DiscussionIn addition to lumbar puncture, the robotic system is suitable for related puncture operations such as discography, radiofrequency ablation, facet joint injection, and epidural steroid injection, as long as the required tissue recognition features are available. These operations can only be carried out once the puncture needle and additional instruments reach the target tissue layer, despite their ensuing processes being distinct.
