Revolutionary Microstereolithography 3D Printing Used To Repair Damaged Nerves

Nerve damage causes delayed responses as well as total loss of sensation. The traditional way of repairing nerve damage is to suture the affected nerves but this procedure often results to more risk of damage. Moreover, surgical procedures to treat nerve damage has limited design capabilities thus it can only treat a few range of injuries. The problems concerning traditional method of repairing nerve damage has led researchers to try other things. Researchers from the Sheffield University are lo

Desktop 3D Printing of CT Scan Images

This is a time of rapid growth in medical 3D printing. The technology allows us to take an individual patient’s scan information and create physical models, which can be used in any number of clinical applications. The industry standard DICOM image files from CT and MRI scanners can be converted into 3D files, such as STL (for stereolithography) files. These digital models can then be uploaded to a 3D printing service bureau or printed on one of the currently available professional grade printer

News and Thoughts about Medical 3D Printing

3D printing has been integrated into the surgical procedures of many physicians, as it has proved very useful in the planning stages of a surgery. It allows doctors to operate with more accuracy and precision by providing a means for surgeons to become acquainted with three-dimensional models of their subjects beforehand. These models provide a holistic view of the part of the body under examination, which affords the surgeon time to assess the model and make changes in their surgical procedur

3D Bioprinting Helps Develop Synthetic Blood Vessels

3D bioprinting is an important technology used in the medical industry. One of its most recent applications is the creation of synthetic vascular grafts that can be used to replace unhealthy blood vessels of patients who underwent coronary or bypass surgery. Traditional vascular grafts work by repurposing the existing blood vessels from a donor or from the patient’s body. The problem, however, is that sources of good and healthy blood vessels are often very difficult to come by. This is the rea

Cardiologists use 3D printed heart to treat arrhythmia

Cardiologists in Aalst, Belgium, 3D printed the hearts of two patients for preprocedural planning in the treatment of arrhythmia (irregular heartbeat). There are different types of arrhythmia and treatment thereof varies. Some conditions don’t require any treatment, while others call for medication or surgical procedures. One minimally invasive procedure is catheter ablation. During this procedure, a catheter delivers high-frequency electrical energy to a small area of tissue inside the hea

3D Printing Makes Cosmetic Solutions for Children More Accessible

In the past, children born with a congenital deformity or who suffered a deformity after cancer or another illness had few options to fix these issues. Many prostheses are prohibitively expensive, as they are often considered to be ‘cosmetic’ by insurance companies and are therefore not covered. This puts parents in a difficult place, especially when the child will shortly grow out of expensive prostheses. In some cases, the necessary surgeries to fix the cosmetic issue were too risky. Thanks to

3D Printing Gave Hope To A Girl Suffering From Rare Facial Distortion

3D printing is a technology that is widely used in the medical field. Recently, a girl suffering from a rare facial defect called Tessier facial cleft found new hope from 3D medical printing. The Tessier facial cleft is a condition that leaves a fissure on the skull. In most cases, patients suffering from this condition need to undergo complicated surgeries that may put their lives at risk. The patient, Violet Pietrok, was born without a nose because of her condition. Moreover, her eyes were al

3D bioprinting Creates Synthetic Tracheal Cartilage

The trachea is one of the most understated parts of the respiratory system. Also called the windpipe, it is a tube that connects the larynx and pharynx to the lungs. The trachea is a rigid tube that is made up of several cartilage rings called the cricoid cartilage. The cartilage is a necessary support system that allows the trachea to remain open. It also prevents the collapse of the trachea with the sudden movements made on the neck. While trachea seems to be a very sturdy organ, there are ti

How 3D Printing is Aiding New Discoveries in Human Evolution

It’s easy to think of the benefits of 3D printing for teaching anthropology. The new technology allows professors to digitalize fragile fossil and bone samples for classroom use—creating a great visual teaching aid. As it turns out, 3D printing has considerable benefits for anthropologists outside of the classroom as well. For one, increasing access to fossil samples for scientists is putting collaborative research on the fast track. Digitizing fossils and making the files available to universi

3D Printing Is A Promising Technology To Treat Patients Suffering From Heart Problems

Heart problems among children are one of the most difficult cases that surgeons have to deal with. The common reason for this is that the size of the heart is tiny which makes it difficult to conduct the operation. However, doctors from St. Thomas Medical Hospital in London used 3D printing technology to help pediatric patients with heart problems. 3D printing specialists, Gerald Geli, and Professor David Anderson created a medical innovation that can likely save many lives of patients sufferin
