The modular and variable stiffness structure of exoskeleton enable the adaptation to different human joint, improving the characteristics of physical human-robot interaction. The DTS-VSA is designed based on the pulley-cable-spring preloading principle and tendon sheath transmission, and its stiffness model is developed through quasi-static force balance analysis. To realize coordinated and active power argumentation, a fuzzy adaptive assistive controller integrated with human joint torque and stiffness estimation is proposed based on surface electromyography.

Laminectomy drilling requires precise manual control to mill bony tissue while preserving spinal segment integrity and avoiding breaches in the dura–the protective membrane surrounding the spinal cord. Despite unintended dural tears occurring in up to 11.3% of cases, no assistive tools are currently utilized to reduce this risk. Variability in patient anatomy further complicates learning for novice surgeons. This study introduces CAPTAiN, a critical anatomy-preserving and terrain-augmenting navigation system that provides layered, color-coded voxel guidance to enhance anatomical awareness during spinal drilling. CAPTAiN was evaluated against a standard non-navigated approach through 110 virtual laminectomies performed by 11 orthopedic residents and medical students. CAPTAiN significantly improved surgical completion rates of target anatomy (87.99% vs. 74.42%) and reduced cognitive load across multiple NASA-TLX domains. It also minimized performance gaps across experience levels, enabling novices to perform on par with advanced trainees. These findings highlight CAPTAiN’s potential to optimize surgical execution and support skill development across experience levels. Beyond laminectomy, it demonstrates potential for broader applications across various surgical and drilling procedures, including those in neurosurgery, otolaryngology, and other medical fields.","PeriodicalId":73318,"journal":{"name":"IEEE transactions on medical robotics and bionics","volume":"7 3","pages":"1125-1138"},"PeriodicalIF":3.8,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144887794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the teleoperation mode inherently causes the loss of force perception, increasing surgical risks and limiting the clinical application of vascular interventional robots. Furthermore, existing robot systems lack the ability to enhance surgeons’ force perception and operational transparency. To address these limitations, we developed an intuitive interface with enhanced haptic feedback for vascular interventional robot. Our approach involved three key innovations: Firstly, we designed a magnetism-based feedback mechanism based on the equivalent magnetic charge method to provide high-precision and real-time force feedback. Secondly, we proposed a feedback enhancement model based on surgeons’ experience to reduce damage to vulnerable vascular areas. Thirdly, a dynamic feedback compensation strategy was presented, aiming at addressing the issue of vascular wall rupture resulted from the rapid decay of feedback force during instantaneous guidewire penetration through lesions in surgical procedures. Finally, we conducted a series of experiments to assess the accuracy, dynamic tracking ability, and overall effectiveness of our system. The results demonstrate the developed haptic interface not only improves surgical transparency but also reduces the risk of vascular injury and puncture, thereby advancing the clinical applicability of vascular interventional robots.","PeriodicalId":73318,"journal":{"name":"IEEE transactions on medical robotics and bionics","volume":"7 3","pages":"1051-1061"},"PeriodicalIF":3.8,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144887667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a single sensing medium and across the different diameters tested, the best estimated resolution of just under 4g and 0.07mm is achieved with the 12mm sensor, filled with 1.5mL using pressure sensing only. Furthermore, the SA is demonstrated in two probe applications and as part of a soft robotic implant for tissue-loading based tissue regeneration. The SA showed the ability to distinguish between different objects or areas of varying stiffness, as part of both a rigid-bodied and soft-bodied probe, as well as being able to predict force and displacement from the lengthening and retraction of a soft implant.

However, it imposes demands on the surgeon’s operation. To reduce the surgical complexity, this study developed a highly dexterous operative tool for MIS procedures. The tool utilizes the widely adopted radiofrequency ablation (RFA) technology in surgical to separate tissues by generating heat through high-frequency currents. It consists of three sets of grippers and radiofrequency (RF) transmitters at their tips. The tool enables intact capture and separation the lesion, thereby eliminating the need for an additional abdominal incision compared to traditional methods and reducing the complexity of liver tumor resection in confined spaces. To minimize the impact on healthy tissue, this paper proposed a calculation method that determines the tool’s key structural parameters and singularity position based on the lesion size, resulting in a lesion volume that constitutes approximately 48.4% of the excised area. Given the high-resistance lever mechanisms in the usage scenario, auxiliary tensiles utilizing RF transmitters are introduced. Simulation analysis confirms that this method reduces the tool’s maximum hinge forces and torques to one-quarter of its original value.

Autonomous robotic electrosurgery has demonstrated the potential to achieve more accurate and consistent resection margins compared to manual methods, thereby improving surgical outcomes. However, current autonomous systems face challenges in tracking tissue deformation during electrosurgical cutting due to unpredictable and complex soft tissue dynamics. Failure to monitor and adapt to tissue deformation can significantly compromise resection precision. This paper presents an autonomous closed-loop robotic electrosurgery system to enhance surgical precision via 3D tissue tracking and image-based feedback control utilizing a Red Green Blue – Depth (RGB-D) sensor. The developed 3D tissue tracker employs CoTracker, a deep learning-based model for markerless tracking, complemented by a tool-occlusion algorithm to achieve tissue deformation tracking with no prior knowledge of the tissue model. The estimated deformation is fed into a fuzzy logic controller, which dynamically adjusts the cutting velocity to minimize cutting error during electrosurgery. The system’s efficacy was validated using ex vivo porcine tongues, demonstrating a 55% reduction in average cutting error (from 1.2 mm to 0.54 mm, <inline-formula> <tex-math>$plt 0.001$ </tex-math></inline-formula>) in closed-loop operations (N=6) compared to open-loop cutting without feedback control (N=3).

Because these procedures are so technically challenging to perform, many patients have limited access to high-quality treatment. Although various robotic systems have been developed to enhance navigation capabilities, they can also apply high stresses due to sliding against the vascular walls, impeding movement and raising the risk of vascular damage. Soft growing robots offer a promising alternative since their method of movement via eversion minimizes interaction forces with the environment and enables follow-the-leader navigation through tortuous paths. However, reliable steering of small-scale growing robots remains a significant challenge. We propose a robot architecture that combines a hydraulically-actuated, soft growing robot with a soft, tendon-driven notched continuum robot to overcome the challenges of steering for small-scale growing robots in endovascular procedures. The soft notched continuum robot successfully steers around the most difficult aortic arch type, and a 2.67 mm diameter growing robot—comparable in size to current catheters—deploys from the tip, pulling an aspiration catheter through extremely tortuous vessels. We present the design, manufacturing, and control of the notched continuum robot, growing robot, and proximal actuation subsystem. Overall, this robotic architecture facilitates active steering in proximal anatomy and navigation in tortuous distal vessels, with potential to reduce procedure times and expand access to care.","PeriodicalId":73318,"journal":{"name":"IEEE transactions on medical robotics and bionics","volume":"7 3","pages":"1029-1040"},"PeriodicalIF":3.8,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144887775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, in advancing FBR development, roboticists sometimes stray from or overlook practical surgical considerations, which might impede its clinical implementation. This review aims to bridge this gap by offering an engineering-focused perspective enriched with critical medical insights to drive the clinical translation of next-generation FBRs. We begin by highlighting the medical significance and current state of FBR research. Then, we outline the “ambient environments” of FBRs: the supported procedure, robotic system, steering tools, and deployment modes. Subsequently, we summarize recent progress in FBR technology, focusing on two key areas: procedure-specific design and modeling to improve intervention capabilities, and autonomous navigation and control strategies to enhance autonomy.

Considering the variation among trial and individual differences, we investigated the best-fitted probability distribution model, calculated the expectation and deviation in each index using the reliability design method, and constructed the response surface for the relationship between factors. Furthermore, we optimized the surgical robot using the satisficing trade-off method. Finally, when comparing theoretical and experimental values for the best solution, relative errors in suturing error and muscle burden were less than 7.14% and 15.1%, respectively.
