However, training outside the operating room is limited by the lack of portability and high cost of high-fidelity simulators. The aim of this study is to present the ArthSim hybrid simulator, a low-cost portable device for the training of psychomotor skills of orthopaedic surgeons in arthroscopic knee surgery. The ArthSim simulator consists of a physical model of the knee with an integrated motion tracking system with a virtual reality application that captures and replicates the movements of the knee joint and the two arthroscopic instruments inside the virtual model, in a mixed reality approach to arthroscopy training. The functionality of ArthSim's technology was evaluated in two experiments: static and dynamic. The interaction of the physical knee joint and the arthroscopic instruments within the virtual model was evaluated by eight orthopaedic surgeons, who recreated the common positions of the knee, arthroscope, and instruments during the exploration of the internal structures. The results indicated a surgical total workspace of 80 mm3 with a range of motion of 115° for flexion, 23° for abduction, and 33° for rotation in the knee joint. The measurements showed linearity and repeatability with errors below, for motion capture. Feedback provided by orthopaedic surgeons on ArthSim was used to identify the device's points of improvement. The ArthSim simulator provides an effective alternative for arthroscopic training in a hybrid simulation approach, offering natural haptics to enhance the surgical experience of orthopaedic surgeons.","PeriodicalId":20666,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine","volume":" ","pages":"9544119251328414"},"PeriodicalIF":1.7,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143754312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, the simulation model of soft tissue indentation experiment was established to obtain the mechanical response under continuous loading condition. The mechanical response of kindy tissue under discontinuous loading was obtained by the actual indentation experiment. Secondly, the mechanical response is predicted and the influence of loading parameters on the prediction accuracy is analyzed. The mechanical response under continuous loading was obtained by simulation, and the mechanical response under non-continuous loading was obtained by indentation experiment. The proposed advanced prediction method is verified by the obtained mechanical responses. The results show that the proposed method can predict the mechanical response of soft tissue well. The proposed prediction algorithm is helpful to predict the mechanical response in advance and avoid the potential tissue damage caused by surgical operation.","PeriodicalId":20666,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine","volume":" ","pages":"9544119251327646"},"PeriodicalIF":1.7,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143677086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the availability of different types of materials suitable for 3DP and healthcare applications, this technology allows for the precise fabrication of patient-oriented prosthetics, dental implants, and orthopedic devices, significantly improving fit and functionality. Additionally, 3DP drugs, such as Oral Dispersible Formulations (ODFs) and polypills, are surpassing the traditional \"one pill fits all\" concept, offering more tailored medication solutions. This innovation also supports the development of personalized medications and bioprinted tissues, opening the way for advancements in regenerative medications and tailored therapies. 3D-bioprinted organs are addressing the growing demand for organ transplants. In surgical planning, 3D-printed anatomical models provide students and professionals with hands-on practice, which is crucial for skill development and understanding complex anatomies. Surgeons can also practice and refine techniques before actual procedures, enhancing precision and improving outcomes during real operations. This paper focus on highlighting the progression and motivations behind the cross-disciplinary applications of AM within the healthcare sector providing customized medical devices, drug delivery systems and diagnostic tools for personalized treatment and skill refinement.

Two thousand two hundred fifty distinct items were discovered after an extensive search. Based only on the title, 250 were included. Two hundred papers were deemed ineligible after the abstracts were assessed. The remaining 26 articles were shortlisted after screening titles and abstracts and categorized based on treatment methods for hand tremors. According to the study's findings, deep brain stimulation (DBS) and electrical stimulation both reduced tremors considerably. It was also evident that attenuation systems and passive devices lessen the effects of tremors; target tracking tasks can lessen physiological tremors in postural posture; ET may have better hand functions after cold water treatment than warm water or at baseline; and targeted ultrasound thalamotomy is an effective treatment for ET, as it improved quality of life (QoL) significantly. Additionally, the design, development, and evaluation of wearable devices and pharmaceutical interventions for tremor suppression were investigated in detail. The main objective was to perform a comparative analysis of the merits and demerits of both treatment methodologies in terms of functional outcomes, users' comfort, and side effects. The review highlights wearable devices as a beneficial option for tremor suppression, offering comfort, safety, and advanced technology over pharmaceutical intervention methodologies.","PeriodicalId":20666,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine","volume":" ","pages":"9544119251325115"},"PeriodicalIF":1.7,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143634395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The novelty of the work stems from its integration of deep learning with a robotics platform for identifying emotional pragmatics deficits. In this study, the proposed methodology utilizes the implementation of machine and DL-based classification techniques, which have been applied to a collection of open-source datasets to identify audio emotions. The application of pre-processing and converting audio signals of different emotions utilizing Mel-Frequency Cepstral Coefficients (MFCC) resulted in improved emotion classification. The data generated using MFCC were used for the training of machine or DL models. The trained models were then tested on a randomly selected dataset. DL has been proven to be more effective in the identification of emotions using robotic structure. As the data generated by MFCC is of a single dimension, therefore, one-dimensional DL algorithms, such as 1D-Convolution Neural Network, Long Short-Term Memory, and Bidirectional-Long Short-Term Memory, were utilized. In comparison to other algorithms, bidirectional Long Short-Term Memory model has resulted in higher accuracy (96.24%), loss (0.2524 in value), precision (92.87%), and recall (92.87%) in comparison to other machine and DL algorithms. Further, the proposed model was deployed on the robotic structure for real-time detection for improvement of social-emotional pragmatic responses in individuals with deficits.

This research aimed to investigate the effect of BI and PT on hip IFROM, IFSZ, and the BI rate. Using this algorithm to calculate a case, we found that when considering BI, (1) the upper limit of the hip IFROM was decreased, and the different PT affected the upper limit of the hip IFROM of various movements; (2) the BI rate of the flat-rim liner in standing and sitting postures were 54.6% and 67%; and (3) the maximum IFSZ size of the flat-rim liner was reduced by 12%, the reduction rate of the combined pelvic position with a non-zero IFSZ size was 83.2% for the flat-rim liner. Consideration of BI further reduces the IFROM, the IFSZ size, and the number of the combined position of the pelvis with a non-zero IFSZ size of the hip joint.

The images were uploaded into BDL and automatically converted into a standardized 8-bit grayscale uncompressed TIFF format. TB regions of interest were then selected on the standardized images, and a data catalog containing metadata information about the regions was constructed. Next, TB texture parameters were calculated for the regions using Variance Orientation Transform (VOT) and Augmented VOT (AVOT) methods and stored in XLSX files. The files were uploaded into BDL, and then transformed into CSV files and cataloged. Results showed that the BDL efficiently transforms images and catalogs bone regions and texture parameters.

An alternative surgical intervention technique using injectable biodegradable cog threads was suggested. The application of Finite element analysis (FEA) to this research allows us to personalize and select suitable POP correction techniques and study the effect of alternative reinforcement techniques. The 3D computational model of the vagina will be used to simulate defect repair using cog threads. To accurately model this, we conducted uniaxial tensile tests on both the polycaprolactone (PCL) cog threads and the sow's vaginal tissues, which mimic human tissue, providing vital data for precise finite element modeling.
