ABSTRACT Background Growth rods are the gold standard for treating early‐onset scoliosis (EOS). However, current treatments with growth do not optimize spinal in EOS patients, and frequent distraction surgeries significantly increase complications, imposing considerable economic psychological burdens on patients. An improved rod is urgently required to address need dynamic external regulation. Methods This study designed a novel (NGR) unidirectional sliding regulation capabilities. By...
The efficacy of laminectomy procedures is contingent on the method resection. objective this study was to investigate impact different methods resection surgical safety automated robots, an area that remains uncharted. Lamina surgeries using both drilling and layer-by-layer methods, are performed ovine spinal samples. An analysis force lateral deviation at end robotic arm conducted. For lamina average peak for 1.21 N, deviations within 1 mm. method, reaches 2.39 1.6 During resection,...
Posterior pedicle fixation technique is a common method for treating thoracolumbar burst fractures, but the effect of different techniques on postoperative spinal mechanical properties has not been clearly defined, especially adjacent segments. A finite element model T10-L2 with moderate T12 vertebra fracture was constructed to investigate biomechanical behavior three posterior screw techniques. Compared traditional short-segment 4 (TS-4) and intermediate long-segment 6 (IL-6), mono-segment...
The movement of the cervical spine should be restricted throughout rehabilitation phase after it has been injured. Cervical orthosis is commonly utilized in clinical settings to guarantee stability. However, date, investigations are limited patient-specific fixation orthoses. This study provides a new idea for making personalized CT data patient's were collected, then mimics used reconstructing skin spine, Geomagic Studio was surface fitting, Inspire structural topology optimization,...
Paratroopers are highly susceptible to lower extremity impact injuries during landing. To reduce the ground reaction force (GRF), inspired by cat paw pad and triply periodic minimal surface (TPMS), a novel type of bionic cushion sole for paratrooper boots was designed fabricated additive manufacturing. A shear thickening fluid (STF) used mimic unique adipose tissue with viscoelastic behavior found in pads, which is formed dermal layer encompassing subcutaneous acts as primary energy...
Numerous screw fixation systems have evolved in clinical practice as a result of advances insertion technology. Currently, pedicle (PS) technology is recognized the gold standard posterior lumbar fusion, but it can also some negative complications, such loosening, pullout, and breakage. To address these concerns, cortical bone trajectory (CBT) has been proposed gradually developed. However, still unclear whether achieve similar mechanical stability to combination + provide suitable...
There is a high risk of serious injury to the lower limbs in human drop landing. However, cats are able jump from same heights without any sign injury, which attributed excellent performance their attenuating impact forces. The bionic study falling cat landing may therefore contribute improve landing-shock absorbing ability humans. contributions limb joints energy absorption remain unknown. Accordingly, motion capture system and plantar pressure measurement platform were used measure joint...
Nanoparticles play a vital role in bone tissue repair engineering, especially iron oxide nanoparticles (IONPs), which have magnetic properties, semiconductor and nontoxicity at the same time, their applications biomedicine received widespread attention. This review summarizes excellent performance of IONPs enhancing scaffold functions, promoting stem cell differentiation, labeling positioning, order to understand research progress future development trends as well security issues. Firstly,...
Biological armors can provide an effective protection against predators. In this study, inspired by conch shell, beetle exoskeleton, and nacre, three different types of bionic composites plates were fabricated: Bio-S, Bio-B, Bio-N, as well equivalent monolithic plate formed from the same stiff material designed manufactured additive manufacturing, respectively. Low velocity impact tests using drop tower conducted to study their resistance. Experimental findings indicated that Bio-S composite...
The turtle carapace has a high level of protection, due to its unique biological structure, and there is great potential use the structure improve impact resistance composite materials using bionic theory. In this paper, chemical elements as well mechanical properties, were investigated by studying composition compounds in each part. addition, sandwich composed plate, core, backplate, was designed modeling software based on microstructure keratin scutes, spongy bone, spine carapace....
Cats are able to jump from a high-rise without any sign of injury, which is attributed in large part their impact-resistant paw pads. The biomechanical study pads may therefore contribute improving the impact resistance specific biomimetic materials. present aimed at investigating mechanics pads, revealing biomechanism macro- and microscopic perspectives. Histological micro-CT scanning methods were exploited analyze microstructure mechanical testing was conducted observe macroscopic...
Background: The cause of the adjacent segment degeneration (ASD) after fusion remains unknown. It is reported that facet joint stresses increase anterior cervical discectomy and fusion. This stress rate may lead to tissue injury. Thus far, load unclear. Methods: Six C2–C7 cadaveric spine specimens were loaded under four motion modes: Flexion, extension, rotation, lateral bending, with a pure moment using 6° robot arm combined an optical analysis system. Tecscan pressure test system was used...
Abstract Background Spatial positioning is the key function of a surgical navigation robot system, and accuracy most important performance index such system. Methods The kinematic parameters six degrees freedom (DOF) arm were used to form transformation from intraoperative fluoroscopy images robot's coordinate system without C‐arm calibration solve redundant DOF problem. influences three typical error sources their combination on final investigated through Monte Carlo simulation.
