A combination of probe holder and laser navigation

Abstract Standard diagnostic ultrasound imaging procedures heavily rely on a sonographer for image acquisition. Given the ultrasound probe is manually manipulated by the sonographer, there is a potential for noise artifacts like blurry acquired images caused by involuntary hand movements. Certain surgical procedures can also cause patients to exhibit involuntary “jumping” movements while on the operating table leading to further deterioration in ultrasound image quality. In this study, we attempt to mitigate these problems by fabricating a 3D-printed ultrasound probe holder. Due to the lightweight nature of the device, it can attach to surgical retractors without influencing the functionality of the retractor. Therefore, the 3D printed probe holder not only reduces relative motion between the probe and the patient, but also reduce the need for a sonographer during complex surgeries.

SUMMARYThis paper introduces the design and the optimization of a probe holder robot for tele-echography applications. To define its kinematic architecture, an approach based on motion capture of an expert's gestures during ultrasound examinations was proposed. The medical gestures analyzed consisted of ultrasound probe movements and were used to characterize the kinematic specifications of the proposed manipulator. The selected architecture was a Spherical Parallel Mechanism (SPM) with 3 degrees of freedom (DoF) and its optimal synthesis was performed using real-coded Genetic Algorithms (GA). The optimization criteria and constraints were established thanks to the collaboration of medical experts and were successively formulated and solved using mono-objective and multi-objective functions.

SUMMARY:Regional cerebral blood flow (rCBF) during internal carotid artery (ICA) occlusion for endarterectomy can be measured without inconvenience using the probe holder illustrated.When mean ipsilateral hemispheric CBF exceeds 20 ml/100 gm/min, an intraluminal bypass is not necessary (63% of patients), except in patients with extensive cerebrovascular disease in whom rCBF should also exceed 20 ml/100 gm/min in all areas. ICA “stump” pressure is falsely high in about 20% of patients, and is therefore not a dependable criterion for selecting patients who need shunting.While intraoperative shunting is capable of restoring pre-occlusion CBF levels, it does not eliminate the risk of intraoperative ischemic neurological deficit of probable embolic origin.
