Hernia repair is the most common surgical procedure in world. Augmentation with synthetic meshes has gained importance recent decades. Most of published work about hernia focuses on technique, outcome terms mortality and morbidity recurrence rate. Appropriate biomechanical engineering terminology frequently absent. Meshes are under continuous development but there little knowledge public domain their mechanical properties. In presented experimental study we investigated properties several...
Background The ergonomics of flexible endoscopes require improvement as the current design carries a high risk musculoskeletal injury for endoscopists. Robotic systems offer solution by separating endoscope from control handle, allowing focus on and usability. Despite increasing interest in this field, little attention has been paid towards developing ergonomic human input devices. This study addresses two key questions: How can handheld devices robotic endoscopy be designed to prioritize...
A recent focus has been on developing wearable health solutions that allow users to seamlessly track their metrics during daily activities, providing convenient and continuous access vital physiological data. This work investigates a heart rate (HR) monitoring system compares the HR measurement from two potential sites for foot technologies. The proposed used commercially available photoplethysmography sensor (PPG), microcontroller, Bluetooth module, mobile phone application. measurements...
This paper describes an underwater robot navigation strategy in flow. Our aim is to demonstrate that knowing the relative flow speed advantageous because it permits using more energy efficient and stable control for trajectory following. We use a biomimetic moves uniform side-slipping maneuver. Side-slipping move laterally with respect incoming by exploiting its passive dynamics. The maneuver controlled adjusting heading of implement simple PID controllers controlling motion transversely....
Soft tissue defects following resectional surgery or trauma often result in deadspaces and require free pedicled flaps. A programmed formation of filling with enhanced biomechanical properties could be helpful. This study examined the effects on wound healing acellular dermal matrix (ADM) seeded autologous fibroblasts a standardized rodent model. As pre- postoperative radiotherapy is standard many treatments malignancies, we also investigated additional radiotherapy. Fischer rats were...
A prototype of a powered knee orthotic device was developed to determine whether fractional external torque and power support the relieves biomechanical loads reduces muscular demand for subject performing sit-to-stand movements. With this demonstrator, consisting subsystems actuation, kinematics, sensors, control, all relevant sensor data can be acquired full control is maintained over actuator parameters. series-elastic based on direct current motor provides up 30 Nm via hinge joint with...
In active knee orthoses, quiet, powerful, and light-weight actuators are required to support the user during challenging tasks like sit-to-stand stair climbing. The twisted string actuation concept, based on parallel arranged strings by a small DC motor, is promising approach cover defined requirements. For characterisation of strings, test bench introduced investigate transmission failure behaviour transmission. application different conditions for requires mechanical load which generated...
Abstract The global shortage of healthcare staff has led to high workloads and subsequent risks patient well-being. One the professions affected is that scrub nurse. Robotic nurse systems have potential reduce workload assist in handling surgical instruments. Existing approaches mostly use two-finger grippers or electromagnetic grippers. However, it assumed a granular jamming gripper more suitable for various instruments, regardless material shape. A gripping unit based on attached robotic...
Spine surgeries are particularly high-risk procedures with the imminent danger of spinal cord and blood vessel injuries. High accuracy safety important aspects in use medical devices during invasive interventions. For exact positioning drill hole, tip pose recognition bone layer breakthrough detection is required. This paper presents a concept design first results novel navigated handheld surgical device for drilling integrated thrust force sensing active optical markers real-time...
Abstract This paper focuses on determining the cable tension required for a cable-driven endoscopic manipulator to reach given position under an external load at end effector. The aim is restore initial of effector without force. A simulation was performed using MATLAB, where mathematical models and algorithms were used calculate tension. model, based Optimized Motion Estimation Analysis, considers joint stiffness influence gravity, in addition tensions load. algorithm minimizes sum moments...
In this paper we present a new single port robotic system particularly designed for access surgery in the field of colon cancer. contrast to most state art systems two intracorporeal manipulator arms are set up using parallel kinematic structure with 5DOF, which integrated into shaft 38mm diameter. The and its workspace discussed detail. As unique feature, kinematics uses translation rotation three rods per manipulation arm. Using approach enables dynamic, stiff precise movements needed...
