A deformable patch-based transformer for 3D medical image registration
ConclusionWe proposed an unsupervised registration network and evaluated its performance in deformable medical image registration. The results of the evaluation metrics showed that the network structure outperformed state-of-the-art methods for the registration of brain datasets.

Image-based recognition of surgical instruments by means of convolutional neural networks
ConclusionWith recognition accuracies of up to 99.9% on a highly meaningful test data set, recognition of surgical instruments is suitable for many track and trace applications in the hospital. But the system has limitations: A homogeneous background and controlled lighting conditions are required. The detection of multiple instruments in one image in front of various backgrounds is part of future work. (Source: International Journal of Computer Assisted Radiology and Surgery)

Eye gaze metrics for skill assessment and feedback in kidney stone surgery
ConclusionWe show that a non-negligible difference holds between novice and expert surgeons ’ gaze metrics in kidney stone identification in phantoms. Expert surgeons demonstrate more targeted gaze throughout a trial, indicating their higher level of proficiency. To improve the skill acquisition process for novice surgeons, we suggest providing sub-task specific feedback. This approach p resents an objective and non-invasive method to assess surgical competence. (Source: International Journal of Computer Assisted Radiology and Surgery)

A sensorized modular training platform to reduce vascular damage in endovascular surgery
ConclusionWe investigated an authentic patient-specific training platform with integrated sensor-based feedback functionality for individual skill training in endovascular surgery. The presented method for phantom manufacturing is easily applicable to arbitrary patient-individual imaging data. Further work shall address the implementation of smaller vessel branches, as well as real-time feedback and camera imaging for further improved training experience.

Learning how to robustly estimate camera pose in endoscopic videos
ConclusionWe demonstrate the effectiveness of our solution to robustly estimate the camera pose in challenging endoscopic surgical scenes. Our contributions can be used to improve related tasks like simultaneous localization and mapping (SLAM) or 3D reconstruction, therefore advancing surgical scene understanding in minimally invasive surgery.

Integration of a surgical robotic arm to the connected operating room via ISO IEEE 11073 SDC
ConclusionThe proposed device profile presents a first step toward a uniform technical description model for modular surgical robot systems. The current SDC core standards lack some functionality to fully support the proposed device profile. These could be defined in future work and then included in standardization efforts.

A stiffness-tunable soft actuator inspired by helix for medical applications
ConclusionThe experimental findings indicate that the soft actuator with TPRS can achieve a broad range of stiffness modulation while retaining flexibility. Moreover, the STSA can be designed to have a diameter of 8 –10 mm, which satisfies the diameter requirements of a bronchoscope. Furthermore, the STSA has the potential to be utilized for clamping and ablation in a laparoscopic scenario, thereby demonstrating its potential for clinical use. Overall, these results suggest that the STSA has significant prom ise for use in medical applications, particularly in the context of minimally invasive surgeries. (Source: Intern...
