UNIVERSAL ADAPTOR FOR AN IMAGING DEVICE AND CORRECTOR ASSEMBLY

Published in WO/2023/178631, 2023

The image corrector, pivotal for implementing image distortion correction algorithms, is designed to be seamlessly integrated with specific C-arm devices. Its importance is particularly pronounced in the case of intensifier C-arms, which, unlike their flat-panel counterparts, are more prone to significant image distortion. A challenge, however, arises from the lack of uniform design standards across different C-arm models. To address this issue and ensure both appropriate and precise integration, a universal image corrector adapter has been meticulously developed. This adapter is tailored to accommodate the varying design specifications of C-arm devices, thereby ensuring optimal functionality and accuracy of the image correction process.

MONOPOLAR SURGICAL APPARATUS

Published in WO/2021/217339, 2021

This innovative and versatile energy-based device (EBD) integrates multiple functions [coagulation, cutting, irrigation, suction] into a single, comprehensive tool. Despite its multifunctionality, surgeons have expressed concerns regarding the cumbersome and repetitive task of cleaning tissue eschar. Typically, this requires removing the device from the abdomen, an extra step that not only prolongs the surgery but also risks injuring the patient through repeated contact with the abdominal wall. Additionally, such removal can lead to the loss of pneumoperitoneum. The distinctive feature of this innovation, setting it apart from conventional devices, lies in its design at the distal end of the electrode. Here, a specially designed valve and cleaning mechanism allow for in-situ cleaning of the eschar, eliminating the need to withdraw the device from the abdomen. This advancement significantly streamlines the surgical process, enhancing both efficiency and patient safety.

ELECTROSURGICAL SYSTEMS

Published in WO/2021/022510, 2021

This innovation represents a significant advancement in energy-based medical devices (EBDs), specifically tailored for laparoscopic surgery applications. It’s ingeniously designed to assist surgeons in two critical areas. Firstly, it provides an invaluable aid in accurately locating bleeding spots within blood ponds, a common challenge in the minimally invasive environment of laparoscopic procedures. Secondly, this device addresses the issue of surgical plume, a frequent obstacle to clear visualization during these surgeries. By effectively managing and reducing surgical plume, it ensures that surgeons maintain an unobstructed view of the surgical site, thereby enhancing both the safety and efficiency of the operation. This dual functionality marks a notable leap forward in surgical technology, offering tangible benefits in operative precision and patient outcomes.
