We present the design of a UHF RFID tag-sensor to automate the process of counting sharps used in the operating theater with the end goal of minimizing the chance of accidentally leaving a sharp inside the patient post surgery. We demonstrate how our sensor is capable of differentiating between three popular sharp sizes by correlating sharp size to a change in the signal response of the RFID tag....
Brachytherapy is a widely used treatment for patients with localized cancer where high doses of radiation are administered to cancerous tissue by implanting radioactive seeds into the prostate using long beveled-tip needles. Accurate seed placement is an important factor that influences the outcome of the treatment. In this paper, we present and study the suitability of a new framework for computer-assisted...
This paper introduces the smart tissue anastomosis robot (STAR). Currently, the STAR is a proof-of-concept for a vision-guided robotic system featuring an actuated laparoscopic suturing tool capable of executing running sutures from image-based commands. The STAR tool is designed around a commercially available laparoscopic suturing tool that is attached to a custom-made motor stage and the STAR supervisory...
In the future of surgery, tele-operated robotic assistants will offer the possibility of performing certain commonly occurring tasks autonomously. Using a natural division of tasks into subtasks, we propose a novel surgical Human-Machine Collaborative (HMC) system in which portions of a surgical task are performed autonomously under complete surgeon's control, and other portions manually. Our system...
The success of medical needle insertion procedures often depends on success of medial needle guidance to a specific target in soft tissue. In this paper application of needle steering with the ability of rotating in the manipulator investigated. For this purpose the mechanism of rotation presented here to obtain all directions of the motion and not to face with polygonal obstacles, which could be...
