These interventions require navigation through complex anatomy irrespective of whether the procedure is performed within organs or vasculature. The need to visualize the device in real-time and to prevent injury to critical anatomical structures further complicates the development of robotic solutions. This work presents the design, modeling, and control of robotic surgical systems to address some of these challenges in minimally invasive procedures.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EFirst, this work outlines the fabrication of tendon-driven joints for micro-scale and meso-scale surgical robots, which enables the development of a robotically steerable needle system for high-dose rate brachytherapy (HDR BT). HDR BT is a crucial radiotherapy treatment that relies on precise needle placement to optimize radiation dose distribution, minimize the number of needles implanted, and avoid damage to critical anatomy. This work demonstrates the development and control of a robotically steerable system for accurate HDR BT needle placement along varied paths.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EAdditionally, this research investigates integrated sensing for robotically steerable guidewires. Guidewires are routinely used in several endovascular interventions, and one significant challenge is the lack of distal tip steerability, particularly in treating peripheral artery disease (PAD) and cerebral aneurysms. Navigating these small, tortuous vessels without causing harm is complex. This research presents the development of integrated shape and force sensing for a robotically steerable guidewire as a potential solution to this challenging clinical problem.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EFinally, this technology is adapted to create a steerable needle system for placing Stereoelectroencephalography (SEEG) electrodes, which are crucial for localizing epileptic seizures in patients with drug-resistant epilepsy. Current procedures require the placement of multiple straight electrodes, which limit achievable paths within the desired anatomical structures. This work introduces a steerable needle system and stiffening sheath capable of placing SEEG depth electrodes along a desired path, enabling new clinical possibilities.\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EDesign, Modeling, and Control of Minimally Invasive Robotic Surgical Systems with Integrated Sensors\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Design, Modeling, and Control of Minimally Invasive Robotic Surgical Systems with Integrated Sensors"}],"uid":"27707","created_gmt":"2024-07-15 18:47:40","changed_gmt":"2024-07-30 17:32:29","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2024-07-30T13:30:00-04:00","event_time_end":"2024-07-30T15:30:00-04:00","event_time_end_last":"2024-07-30T15:30:00-04:00","gmt_time_start":"2024-07-30 17:30:00","gmt_time_end":"2024-07-30 19:30:00","gmt_time_end_last":"2024-07-30 19:30:00","rrule":null,"timezone":"America\/New_York"},"location":"Klaus Advanced Computing Building, Room 1212","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
