Round window, a channel connecting the middle and inner ears, plays an important role in hearing process of human beings. Usually, localized medical treatment to the round window requires surgical treatment to be carried out by professional surgeons. In this paper, we propose a novel approach to explore the potential of robotic-based round window local therapy, leveraging on the technique of stereo...
In this paper a medical robot based on a 3-RPS parallel platform is presented for providing correct screw path in transpedicular fixation surgery. For improving the accuracy of the robot, a calibration approach for 3-RPS with CMM (Coordinate Measuring Instrument) data is developed. Sensitivity analysis of the error source had been done with Monte-Carlo techniques. The results show that the length...
In order to exhibit the surgery instruments in intraoperative image, the tracking system must be introduced so that it may finally achieve the image guide surgery on minimally invasive spine surgery (MISS). To exhibit the tip of the instrument, the transform of the CARM(a device which generates X-ray images) and CT image, the transform of the world and CARM. The more transforms of different space...
Registration is a key issue in image-guided minimally invasive vascular surgery (MIVS) when the electromagnetic device is used to tracking the catheter. We assume that the catheter advances in the vessel along the vascular centerline during MIVS. Based on this assumption, we proposed a dynamic point matching approach for registration, of which the transformation is estimated by aligning the point...
This paper describes the design and development of a miniature 3-axis distal force sensor which can be applied in tissue palpation during minimally invasive surgery (MIS). The sensing principle is based on resistive sensing method that utilizes gauges to measure the strain of a flexible platform when exposed to a force. A novel tripod structure is designed and optimized as the flexible platform, it...
As we know that MIS permits vascular interventions through very small incisions and minimizes the patients' trauma and permits a faster recovery compared. In this document, we present the mechanical and haptic simulation of the MIS VR operation training system. Virtual reality technology for doctors can improve the accuracy and safety of real vascular interventional surgery for vascular interventional...
Single Port Surgery (SPS) and Natural Orifice Transluminal Endoscopic Surgery (NOTES) bring the benefits: reduced surgical trauma and less patient's burden. However, they are still limited in the area of instrument dexterity and operability. This paper presents an Insertable Surgical Robot (ISR) for Single Port Access Surgery (SPAS), this robot uses multi-level architectures in the field of endoscopic...
This paper presents the use of computed tomography image (CT) to generate a 3D workspace in the area of skull base. Our ultimate goal is to develop a surgical robotic system to aid in the endoscopic transsphenoidal surgery. The 3D workspace can benefit both aspects of robot design and intra operative navigation system. In our system, the 3D model of a skull base area is created by the 3DSlicer program...
Mandible reconstruction surgery is an extremely complex and high-risk surgical surgery. The aim of the project is to import the robotics technology into mandible reconstruction surgery, which can reduce the workload for doctors, decrease the difficulty of operation and improve the accuracy and quality of surgery. The development of Mandible Reconstruction Surgery Robotic System (MRSRS) provides a...
It is significant to have accurate localization of surgical instruments in navigated minimally invasive surgery. Moreover, instrument tracking modules are essential for cognitive surgical robotic systems. Commercial optical trackers have been developed with sub-millimeter accuracy, but typically work only at single spectrum — either visible spectrum or infrared spectrum, which limits the sensing and...
Minimally Invasive Surgery (MIS) is less invasive and creating fewer post-operative complications compared with conventional surgery. This results in shorter recover times and, sometimes, outpatient treatment replaces for previously lengthier procedures. So MIS is the latest trend in surgery. However, MIS is usually associated with a limited view of the surgical view area and is difficult to handle...
This paper presents a design and development of Veress Needle Insertion Force Sensing System, and a Veress Needle Insertion Robotic System for acquiring force data for soft tissue insertion. The study reports force data from veress needle insertions, measured to use in our Robot-Assisted Surgical System. The main goal of this work is to develop a virtual reality robotic surgical system which can provide...
