Class of 2017

Introduction to Topic

The internal human body is fascinating. All of the parts inside of humans that have to be working properly at all times are so intricate and detailed. Surgery captures this fascination. New innovations, procedures and protocols are being taught every day in the hospital setting. Laparoscopic surgeries require such precision and accuracy. One problem within laparoscopic surgery is post-op infection and proper sterilization. Surgeons are often under high-pressure situations and do not have time to deal with faulty equipment. The goal of this project is to find an innovative way to reduce the risk of post-op infections after laparoscopic surgeries.

Project Description

During shadowing, I learned that surgical techniques such as using the DaVinci are becoming more common every day. Laparoscopic surgeries reduce scarring and take less time, however, with any surgery, there are still risks that could be reduced through further innovation. The goal of this project is to create a comprehensive and inclusive piece of equipment that serves to sterilize laparoscopes and endoscopes using warm airflow while at the same time sterilizing smaller pieces of equipment such as clamps and scalpels.  By observing multiple laparoscopic surgeries during shadowing and researching about the surgical field I discovered how making these kinds of advancements could reduce the risk for post-op infections during surgery. I concluded that a 3D printed model would be an appropriate way to demonstrate the structure and functionality of such a product. This product would also need to be marketed towards hospitals and medical supply companies, which is why I took the initiative to also launch a website so that the product, in practice, could gain recognition.

Experience Description

All the surgeries I observed during my 52 hour shadowing experience were deemed a success with very few complications. All the surgeries I observed were in the main and not the Surgicenter, where more outpatient surgeries take place. During one surgery, the surgeon slightly nicked the bile duct, but quickly was able to use the Bovie on the particular spot to stop the bile from leaking any further. The bile has a very strong and distinct chemical odor. The most fascinating part of the surgery was at the very end when the gallbladder was being removed. A big is inserted into the abdominal cavity and using the laparoscope, the surgeon guides the bag over the gallbladder and then pulls it out of a very small incision made on the patient’s stomach. It was amazing how complex, but minimally invasive the surgery was. The patient took a long time to wake up from the anesthesia and when I asked the surgeon why it was taking longer than usual he said that it was due the amount of pressure they had to use during surgery partly due to the patient’s breast size. This was one of the most exciting surgeries I was able to observe and alo the most influential in my innovation idea, as perhaps if there was less fogging on the lens, the bile duct could have possibly been prevented from being nicked.  I was most nervous about how all of the surgeons would feel about a high school student observing surgeries. There is a notion that we receive from television that surgeons are often arrogant , however, I found this to be extremely untrue. All of the surgeons I encountered were extremely willing to answer any questions I had and respectful to all other personnel in the operating rooms. All of the twelve hour shifts made me realize how hard all of these employees work all day and how dedicated a person must be to work in one of these fields. Long hours, no breaks, and heartbreaking outcomes are a part of the job description. I have a tremendous amount of respect for all medical personnel, especially after this experience. All of my days at Northwest Hospital were  tiring and exciting experiences,and truly gave me a great idea as to what life working in an operating room is like along with some of the problems that arise.

Innovation Description

After extensive research on directional airflow, autoclaves, and scope warmers, I was able to come up with my final innovation. The name I have come up for this product is EWAD. EWAD stands for Endoscopic Warming and Disinfecting System.The product is the combination of the traditional autoclave and laparoscope scope warmers. However, the major difference here is that this autoclave-type machine utilizes directional airflow instead of typical chemical disinfecting solutions like the scope warmer.  In the research it was discussed the leak problems with typical scope warmers and how this can cause contamination and possibly deadly outcomes to the patient if a post-op infection occurs (Bessel 1996). The box in reality is 45cm by 30cm. The front door of the box consists of an Ipad where the time and type of tools being put into the EWAD can be inputted by the user. Also, on the front is the temperature and pressure gauge that can be manually changed to the correct degree and psi. There is a handle that is pulled to open the device on the front and right side of the machine. The sides of the compartment are left clean and made of stanley steel along with the rest of the product. The back of the machine is where the laparoscope and endoscope tubes are connected. There are three holes on the bottom of the back side. Each is customizable by the buyer to fit whatever size or sizes of tubes they need to fit. These are made of a flexible steel product as these tubes will be retractable. The tubes of the box are made retractable so that they can envelope the enter endoscope to warm it up before surgery, but completely retract once warmed so that the box can be easily transported from operating room to operating room, while not being any awkward and bulky shape. The tubes also consist of a cap that twists on while the endoscope is being warmed and stored and also keeps the tube retracted. Laparoscopes generally come in sizes of 45cm or 30cm with a 5mm, or 10mm diameter, so these are the primary sizes that will be sold, but any size can be custom made.

Previously discussed is what the physical model does. Now I will be discussing how the model was created. I created four individual files on Fusion 360 all under the same project. All the dimensions were proportionately and correctly determined. Because this was the first time I had used Fusion 360, I consulted a family member, who is a civil engineer, who uses this technology constantly. He helped to give advice on how to use the functions of Fusion 360 to help attain sleek lines and correct proportions. He also helped to give insight into how airflow is used in the area of sanitation which I will discuss further when discussing the other innovation, the website. To create this 3D model I reserved a two hour time slot at the Harford County Public Library, Abingdon Branch. There they have their new innovation lab. I had the tremendous pleasure of meeting Annette Gaskins here. She knows everything there is to know about 3D printing and so she was a great asset when printing my model. She was also very intrigued about what I was creating. First, since all my Fusion 360 files were made on a Mac, I had to convert all of the files to stl files. Then these files were inputted into the Makerbot software, what is used in the library. Because my model is very small, I utilized the mini and precise 3D printer the Innovation Lab offers. The print would have taken an enormously long time to print had I not resized it on this software. Every piece has been scaled down to 25% of the original. During my first two hour time slot I printed the base of the innovation, the steel box everything else attaches to. The first print attempt was a success. The next day at Bel Air high school, I printed a demonstrable cap for one of the tubes. This time I used Cura. The print was a success again. The next day I went to the Harford County Public Library again to print the door and the handle, repeating the procedure from the previous day, this time with no help from Annette Gaskins. It was yet again a success. In fact Annette emailed her friend from another library and told her about my project. She called me last week and asked if I would be willing to do an interview about my biomedical innovation for a library magazine interview on teens and 3D printers and what is happening at the Innovation Lab. My interview will be taking place on May 10, 2017.

Because I want my program to be demonstrable, I did not 3D print the retractable tubes, as there is not easily available flexible plastic for printing. Instead, I cut bendy straws that could

sizes to show how different size endoscopes and laparoscopes could fit into the EWADs.  After I had all of the individual pieces ready to go, I used crazy glue to connect all of the pieces. The only pieces not glued for attachment is the cap as I wanted to be able to show the way this cap would twist on and off. Finally, the final product was spray painted with a metallic grey spray paint to give it that stanley steel looking, clean looking finish that would be found in a sterile hospital setting.

When shadowing at Northwest Hospital, I often ate lunch with my mentor in the conference rooms where different drug representatives would give presentations about their products. This gave me the idea to create a website for my product, so that different hospitals could buy the product. The name of the website is warmlabs.com. I began by creating a clean and modern logo with the slogan for the Warm Labs Company being “Compact thermal solutions”. The logo is visually appealing with bright but not overwhelming colors with a box like design abstractly showing the concept of EWADS. EWADS again stands for Endoscopic Warming and Disinfecting System. The home page consists of the company’s mission statement. It also consists of the four main products the company sells: the EWADS, customizable tubes, disinfecting solutions and other general surgical equipment such as scalpels. The website also includes a contact us page as well as a link to the company’s instagram page. The second tab up at the top left of the home page is the About EWADS page, which gives a detailed description of the product. This description states that the Endoscopic Warming and Disinfecting System utilizes directional airflow technology. Instead of using harsh chemicals and liquids that could interfere with surgical procedures, EWADS utilizes pressure and heat. The heat works to kill

bacteria by breaking hydrogen bonds which denature their proteins. This clean air then passes through the warming endoscope tube to provide the perfect anti-fogging temperature as the endoscope enters the body. Lastly, there is the Services Page that is also linked to the EWAD tab. The Services page discusses prices of products. The first service is free equipment tutorials, with our Equipment Tutorials services, clients can feel confident that their medical supply needs will be attended to in a timely manner. At warmlabs.com, your satisfaction is our primary concern — and we go above and beyond to provide personalized attention to all your medical equipment needs. Get in touch with us and see what we can do for you today. Next is the EWADS, This fully-functioning product is revolutionary in the world of medical sanitation. Made from stainless steel, this product is guaranteed to last. Regular autoclave machines can cost up to $5000. Our product is being sold at the incredibly low price of $2500. The most innovative feature of the EWAD is the warming endoscope tube. It gives the patient and the surgeon piece of mind knowing their endoscope is not contaminated. Lastly described are the customizable tubes, for only an additional $150 each, we offer endoscope and laparoscope tubes in any size. This includes length, width, and diameter. This product can be custom built for pediatric, all the way up to geriatric patients undergoing surgery and everywhere in between. You can even choose your own custom colors and logos to add onto your EWAD and tubes for no additional charge. For all of the descriptions on the website, each word and sentence was carefully chosen and edited by a family member, who is an author, to make sure that these descriptions were highly professional for the product to be marketable.

Overall the website consists of calming colors and clean lines. It is very user friendly and simple while still having everything a website needs to have. The information on the website will be put into the project’s oral Powerpoint report. This is what the drug representatives did with their products to get the most positive reactions from possible buyers. To get the most recognition for this product in the real world, I would need to bring the mode of this product to hospitals all over the country and have a stunning sales pitch. The Instagram page is just another way for the product to gain recognition as the page follows hospitals and medical companies so that the company can be updated on what hospitals across the nation are looking for, along with competition and prices. This is another way to advertise deals that Warm Lab products are advertising. All of this planning, Fusion 360 designing, researching, interviewing, 3D printing and website building is what I utilized to attain the rest of the 28 hours in addition to my shadowing experience to complete this project.
