Microsurgery training with smartphone

AbstractMicrosurgery is widely used in experimental research models and clinical surgery. However, microsurgical applications require precise technical skills and continuous training. Here, we proposed a low cost, practical microsurgery model, which can be easily applied using smartphones at home or at office. Test platform was created using latex gloves, and a phone holder was then positioned at one side of a table. A smartphone with 10x magnification was secured on the phone holder. Microsurgical device habit, stitching and knotting exercises by making cuts at different angles on the glove model were performed, which was recorded live under the 10x magnification of the phone camera.We believe that the practical microsurgery model presented in this study can form an important part of basic microsurgery education and also act as an alternative training model owing to its ease of application, easy accessibility and low cost.

AbstractDuring medical education, medical students are often frustrated by difficulties in translating theoretical anatomical knowledge and basic surgical skills (suturing, tissue and instrument handling, and local anesthetic administration) into practice. A common etiological factor for this difficulty, among others, is lack of a low-cost and easy-to-assemble low fidelity suturing model. The purpose of this study is the demonstration of a validated, practical, inexpensive, hand-shaped anatomy training model. It is addressed to medical students and graduates that wish to get acquainted with neurovascular anatomy of the hand and improve their basic surgical skills. The model requires only two latex gloves, cotton, and two different color markers per trainee to draw the course of large nerve and vessels. Construction requires less than 15 minutes. For validation, 80 students participated as volunteers in the demonstration course. They evaluated course usefulness and their own confidence after the course. According to the 5-point Likert scale, the participants’ confidence increased in a statistically significant way (p < 0.05). All participants (100%) stated that their skills were “significantly improved” in terms of instrument handling, anatomy studying, performing digital anesthesia, and suturing technique. Overall experience was rated as “satisfactory” or above. The proposed model enables safe gentle soft-tissue handling, and it resembles a realistic human tissue. Low cost, availability, and fast construction are the most important characteristics, making this validated training model appropriate for acquiring fundamental local anesthesia, respect for hand neurovascular anatomy, and suturing skills.

The Times

This paper provides a detailed analysis on the systematic innovation process in improving the quality control of latex gloves production. The systematic innovation tool such as TRIZ is applied in this case study. Function analysis, cause and effect chain analysis, physical contradiction, By-separation model and 40 Inventive Principles are applied in order to derive some feasible and low cost solutions to alleviate the problem. Findings revealed that the rejected (leaking) gloves on the production line will be manually monitored by a checker during the air blowing test and will be discarded by the same checker instantly. The main root cause is that the quality control worker is not able to concentrate all the times to detect the torn gloves, mainly is due to the fast speed production line and other distractions. The problem is solved by applying function analysis, physical contradiction, by-separation tool and Inventive Principles to generate low cost but elegant solutions within the defined scope of several constraints and without making the production line more complex. Therefore, it can be concluded that TRIZ is a systematic and innovative problem solving methodology.

Rigorous Study

The purpose of the research is to reveal what is to be achieved with the final results 1) Completion of the problems that have arisen to produce new wisdom, 2) Prevent all predicted problems will arise, 3) as a comparison of existing theories. Specifically, the purpose of this study was to determine whether there was a direct influence between training methods and the efficacy of increasing 800 meters running distance at Pattimura University Students Teacher Training and Education Faculty 2015/2016 Physical Education and Recreation Physical Education Study Program. This research was conducted at Patimura University, Faculty of Health and Education, Penjaskesrek Study Program involving 60/17 students in the 2016/17 semester as research subjects. The method used in this study is an experimental method based on SuarsiminArikunto's reference. Experimental research, according to Ali Maksum, is a rigorous study to find out the causal relationship between variables. One of the main characteristics in experimental research is the existence of treatments (treatments) that are worn on the subject or object of the researcher. Research design or research design is a plan and structure of inquiry arranged so that researchers will be able to obtain answers to their research questions. The results showed that to increase the results of 800 meters running in Unipatti Ambon FKIP Penjaskesrek students can be improved through interval training methods, continuous training methods, and fartlek training methods by controlling endurance first.

Using QR codes to access videos in engineering laboratory classes might be a successful way of building a bridge from concrete to digital content. With QR codes placed on an apparatus, students know exactly which video to watch, allowing them to view the videos while performing the experiment or at home when writing the report. Low-cost videos do not require expensive equipment and software, and keeping them short assures a minimum download time for use with smartphones and tablets. The aim of this chapter is to evaluate the importance undergraduate engineering students attribute to these videos and their reaction to the possibility of accessing them with QR codes scanned by a smartphone or a tablet, using access statistics and video viewings to support the findings. Results show students attributed some importance to the videos, and that the QR codes are very helpful as means to quickly and easily access the videos.

Healthcare Settings

Postpartum haemorrhage remains a leading cause of maternal mortality and morbidity. While conventional obstetrics training curricula describe at length the management of postpartum haemorrhage, obstetrics trainees rarely have exposure to surgical management of postpartum haemorrhage in emergency situations due to reduced hours of training. Procedures such as the transverse or longitudinal haemostatic uterine brace sutures are recognised to be safe, simple and allow for the preservation of the uterus. Training during emergency situations is rarely practical or ideal. We describe a simple model that simulates the atonic postnatal uterus and allows trainees to practise the safe placement of the brace sutures. We use a bovine uterus model with attached broad ligament, bladder and ureters for the transverse haemostatic suture. For the longitudinal brace suture, we use a porcine bladder to simulate the uterus, with the ureters and bladder mesentery simulating the tubes and broad ligaments. The placement of the sutures can be practised with the uterus/bladder closed, or open akin to a caesarean section. Tissue dissection and feedback is almost similar to in vivo conditions. The sutures are inserted and driven using the material and correct placement used during real surgery. Our wet lab training model allows the acquisition, maintenance and enhancement of the required technical skills in a controlled environment, using inexpensive, reproducible and widely available specimens. The model has proved successful in both high and low-resource healthcare settings.
