BackgroundCochlear implantation is a surgical procedure in which an electrode array is permanently implanted into the cochlea to stimulate the auditory nerve and allow deaf people to hear. Percutaneous cochlear access, a new minimally invasive implantation approach, requires drilling a single linear channel from the skull surface to the cochlea. The focus of this paper addresses a major challenge...
Background
When robots mill bone near critical structures, safety margins are used to reduce the risk of accidental damage due to inaccurate registration. These margins are typically set heuristically with uniform thickness, which does not reflect the anisotropy and spatial variance of registration error.
Methods
A method is described to generate spatially varying safety margins around vital anatomy...
Background
Compared with traditional surgical methods, which only rely on doctors' experience, three‐dimensional robot‐assisted navigation technology could locate the lesion more accurately.
Methods
The transformation principle of three‐dimensional navigation system was analyzed. The surgical path was planned on the reconstructed three‐dimensional model. The experimental data of positioning position...
Background
Robot‐assisted pedicle screw insertion has gained popularity in the spinal surgery field. Due to high cost, these spinal robots are not extensively applied in clinical surgeries. Developing an effective robot system with low cost and high clinical acceptability is one of the future trends.
Methods
We developed a novel fluoroscopy‐based robot system for pedicle screw insertion. Four live...
Background
For the robot‐assisted fracture reduction, due to the complex fracture musculoskeletal environment, it is necessary to consider the influence of soft tissue traction on preoperative reduction path planning.
Method
An improved 3D A* algorithm is adopted to plan the fracture reduction path. The distal fragment point clouds are updated to avoid the collision, and the end point coordinates...
Background
High‐quality methods for Magnetic Resonance guided Focussed Ultrasound (MRgFUS) therapy planning are needed for safe and efficient clinical practices. Herein, an algorithm for full coverage path planning based on preoperative MR images is presented.
Methods
The software functionalities of an MRgFUS robotic system were enhanced by implementing the developed algorithm. The algorithm's...
Background
The gold standard workflow for targeting structures in the brain involves manual path planning. This preoperative manual path planning is very time‐intensive and laborious, especially when some outcome measures such as maximum ablation and penetration depth has to be optimised.
Methods
Our novel path planner generates an optimal path which maximises the hippocampus penetration and distance...
Background
Robot‐assisted pelvic fracture closed reduction (RPFCR) positively contributes to patient treatment. However, the current path planning suffers from incomplete obstacle avoidance and long paths.
Method
A collision detection method is proposed for applications in the pelvic environment to improve the safety of RPFCR surgery. Meanwhile, a defined orientation planning strategy (OPS) and...
