Complementary electrostatic interaction between the zwitterionic merocyanine and dipolar molecules has emerged as a common strategy for reversibly structural conversion of spiropyrans. Herein, we report concept-new approach thermal switching spiropyran that is based on simultaneous nucleophilic-substitution reaction interaction. The at spiro-carbon atom promoted due to electron-deficient induced by 6- 8-nitro groups, which responsible isomerization interacting with thiol-containing amino...
A chromogenically reversible, mechanochromic pressure sensor is integrated into a mininvasive surgical grasper compatible with the da Vinci robotic system. The sensorized effector, also featuring two soft-material jaws, encompasses polymeric inset doped functionalized spiropyran (SP) molecule, designed to activate mechanochromism at chosen and providing reversible color change. Considering such tools are systematically in visual field of operator during surgery, change effector can help...
Simulators for gastrointestinal (GI) endoscopy offer the opportunity to train and assess clinician skills in a low-risk environment. Physical simulators can enable direct instrument-to-organ interactions not provided by virtual platforms. However, they present scarce visual realism limited variability their anatomical conditions. Herein, we an innovative low-cost methodology design fabrication of modular silicone colon simulators. The pipeline envisages parametric customization development...
Objective: Surgical graspers must be safe, not to damage tissue, and effective, establish a stable contact for operation. For conventional rigid graspers, these requirements are conflicting tissue is often induced. We thus proposed novel soft based on morphing jaws that increase area with clutching force. Methods: introduced two jaw concepts: DJ CJ. They were designed (using analytical numerical models) prototyped (10 mm diameter, 10 span). Corresponding obtained by integrating the into tool...
The phenomena of droplet impact on an inclined solid surface covered with a pre-existing liquid film are observed using high speed camera at 10000 frames per second. processes spreading, sheet formation, splashing and oscillation analyzed. From the results relationship between spreading velocity time is discussed quantitatively. Besides, effects angle front back factors initiatory also revealed. At angles ranging from 28.0° to 74.7°, it found that decrease angle, deformation degree...
This study reports a novel Hollow Soft Pneumatic Actuator (HOSE), which exhibits 4 degrees of freedom (DOFs).The design consists central hollow cylinder surrounded by four twisting symmetric chambers.By virtue their spiral disposition, each chamber produces diagonal force along the internal composed two components: one parallel to Z axis and other plane X-Y.Both top bottom sections actuator are reinforced avoid deformation, essential for optimal function dexterity HOSE.Different movements...
Abstract Background Hollow, bendable manipulators can advance implant delivery in minimally invasive surgery, by circumventing the drawbacks of straight‐line and fostering single‐port approaches. Variable stiffness are sought to be safe effective. Methods We designed experimentally assessed a cable‐driven articulated/continuum manipulator, devised for cardiac valve delivery. Positioning stiffening were teleoperated, based on cable shortening. Stiffening was parameterized using leading...
Soft-tethered colonoscopes were proposed for safe and effective colon navigation, yet the deployment of front-wheel actuated is hindered by contact interactions with lumen along entire soft tether. To mitigate this problem, study introduces an over-the-tube flexible device aimed to assist colonoscope deployment. The composed three pneumatically driven actuators devised repeatedly perform a two-phase operation: (phase I) advance tether up working position relatively close colonoscope's tip;...
Aortic valve disease is the most common heart in elderly calling for replacement with an artificial valve. The presented surgical robot aims to provide a highly controllable instrument efficient delivery of by help integrated endoscopic vision.A (called ValveTech), intended minimally invasive surgery (MIS) and consisting flexible cable driven manipulator, passive arm, control unit has been designed prototyped. manipulator several features (e.g., stabilizing flaps, tiny cameras, dexterous...
To reduce incidence and mortality, screening of the gastric cavity is crucial to diagnose early-stage cancers. Most cases are concentrated in low/ middle-income countries (LMICs), where medical resources limited. In this paper, we propose a miniaturized, disposable, low-cost soft robotic gastroscope designed for LMICs. The platform composed i) frontal soft-core module, ii) flexible multi-lumen tether, iii) an intuitive control handle, provide a) 180 deg bending angle, b) 360 axial rotation,...
