Minimally invasive surgery instruments based on a four-bar linkage design

Sensorized and Actuated Instruments for Minimally Invasive Robotic Surgery

Minimally invasive surgery (MIS) challenges the surgeon’s skills due to his separation from the operation area which can be reached with long instruments only. To overcome the drawbacks of conventional MIS robotic surgery systems with integrated haptic feedback play an important role. This paper describes the development of actuated and sensorized instruments for minimally invasive robotic surg...

Dynamic Behavior Analysis of a Planar Four-bar Linkage with Multiple Clearances Joint

 In practice, clearances in the joints are inevitable due to tolerances, and defects arising from design and manufacturing. In the presence of clearance at a joint, a mechanism gains some additional, uncontrollable degrees of freedom which are the source of error. Moreover, joints undergo wear and backlashes and so cannot be used in precision mechanisms. In this study, the dynamic behaviour of ...

Role of Minimally Invasive Spine Surgery in Adults with Degenerative Lumbar Scoliosis: A Narrative Review

Background and Aim: Degenerative lumbar scoliosis is a spinal deformity resulting from advanced disc degeneration and facet arthropathy. Given the inconclusive available literature and lack of high-quality data supporting the role of minimally invasive surgical management of degenerative lumbar scoliosis, this review intends to highlight and compare the various viable minimally invasive surgica...
