“…A display of the CT volume with needle path was shown on a monitor. Colin Sutherland [9] proposed a haptic-based simulator for ultrasound-guided percutaneous spinal interventions, which composed of a haptic device to provide force feedback, a camera system to display video and augmented computed tomography overlay, a finite element model for tissue deformation and ultrasound simulation from a CT volume. A lumbar puncture training system presented by Farber et al used a PHANToM Premium 1.5A haptic device [10].…”

A remote haptic collaboration system for lumbar puncture learning and training has been proposed. The study built a physical model for the simulation of interaction force between the needle and different tissues and developed a new protocol for real-time force feedback data transmission. Based on the processing delay and preprocessing interpolation, the negative effects on remote haptic perception caused by network communication can be reduced to a minimum. Experiments were carried out to justify the proposed method. The experimental results show that (1) our physical model agrees well with the reality lumbar puncture; (2) the integrity of received data has been ensured by means of interpolation preprocessing. Our system can provide a good realism and real-time stability for the remote learning and training of lumbar puncture teaching.

“…The capacitive array sensing based training manikin proposed in [8] lacks the underlying anatomical features of the eye and orbit necessary for accurate representation of the training environment. Haptic based simulators [9], [10] require complex finite element tissue deformation models, making them computationally burdensome and slow. Also, optical tracking systems used in [9] require direct line of sight between the imaging system and the needle, thus, restricting the movement of the trainee, who fails to perceive a true training environment.…”

Ophthalmic regional blocks are critical preoperative procedures involving the insertion of a syringe needle into the orbital cavity at such a position and angle that akinesia and analgesia is achieved without damage or harm to the eye and its associated musculature. A training system that accurately represents the orbital anatomical features and provides qualitative feedback on the performed anesthetic technique, can be of immense help in reducing risks involved in regional block administration. In this paper, a training system that employs a special but simple capacitive sensing scheme has been developed. A rapid prototyped eye-model has been used to ensure anatomical accuracy. Capacitive transmitter electrodes placed on the orbital wall along the length of the extraocular muscles are excited with a special excitation sequence and the displacement current at the needle of the syringe is measured using simple electronic unit and a Data Acquisition System, enabling the developed Virtual Instrument to detect the depth of penetration and proximity of the syringe needle to the ocular muscles. Additionally, the system detects needle touch of the muscles accurately. The proposed electrode array system and excitation schemes have been validated on a prototype system thus demonstrating its usefulness for practical training purposes.
