Robot-Assisted Needle Insertion for CT-Guided Puncture: Experimental Study with a Phantom and Animals.

Cardiovascular and interventional radiology
PURPOSE: This study aimed to evaluate the accuracy and safety of robotic CT-guided needle insertion in phantom and animal experiments.

Robotic system for accurate percutaneous puncture guided by 3D-2D ultrasound.

International journal of computer assisted radiology and surgery
PURPOSE: Ultrasound (US)-guided robotic systems can reduce the reliance on the experience and skills of surgeons and enable automatic and accurate percutaneous puncture. Two-dimensional (2D) and three-dimensional (3D) US guidance have various advanta...

A multi-module soft robotic arm with soft actuator for minimally invasive surgery.

The international journal of medical robotics + computer assisted surgery : MRCAS
BACKGROUND: Compared to traditional rigid robotic arms, soft robotic arms are flexible, environmentally adaptable and biocompatible. Recently, most minimally invasive cardiac procedures still rely on traditional rigid surgical tools. However, rigid t...

Optimisation and validation of a co-manipulated robot for brachytherapy procedure.

The international journal of medical robotics + computer assisted surgery : MRCAS
BACKGROUND: Low-dose rate brachytherapy is the referent treatment for early-stage prostate cancer and consists in manually inserting radioactive seeds within the organ to destroy tumorous cells. This treatment is inaccurate leading to side effects. R...

Enhancement of instrumented ultrasonic tracking images using deep learning.

International journal of computer assisted radiology and surgery
PURPOSE: Instrumented ultrasonic tracking provides needle localisation during ultrasound-guided minimally invasive percutaneous procedures. Here, a post-processing framework based on a convolutional neural network (CNN) is proposed to improve the spa...

Magnetically actuated gearbox for the wireless control of millimeter-scale robots.

Science robotics
The limited force or torque outputs of miniature magnetic actuators constrain the locomotion performances and functionalities of magnetic millimeter-scale robots. Here, we present a magnetically actuated gearbox with a maximum size of 3 millimeters f...

Phantom and Animal Study of a Robot-Assisted, CT-Guided Targeting System using Image-Only Navigation for Stereotactic Needle Insertion without Positional Sensors.

Journal of vascular and interventional radiology : JVIR
PURPOSE: To evaluate the feasibility and accuracy of a robotic system to integrate and map computed tomography (CT) and robotic coordinates, followed by automatic trajectory execution by a robotic arm. The system was hypothesized to achieve a targeti...

Machine Learning-Enabled Prediction of 3D-Printed Microneedle Features.

Biosensors
Microneedles (MNs) introduced a novel injection alternative to conventional needles, offering a decreased administration pain and phobia along with more efficient transdermal and intradermal drug delivery/sample collecting. 3D printing methods have e...

Needle path planning in semiautonomous and teleoperated robot-assisted epidural anaesthesia procedure: A proof of concept.

The international journal of medical robotics + computer assisted surgery : MRCAS
BACKGROUND: Epidural anaesthesia is a Percutaneous Procedure (PP) which plays a crucial role in surgical procedures, where accurate needle insertion is still challenging. The objective of this work is to present a Tuohy needle path planning, which al...

An admittance-controlled amplified force tracking scheme for collaborative lumbar puncture surgical robot system.

The international journal of medical robotics + computer assisted surgery : MRCAS
BACKGROUND: The accurate sensing and display of the delicate needle-tissue interaction force to the operator is desirable for needle insertion procedures. It not only plays a significant role in the surgical treatment effect, but also has a great sig...
