When Does Titanium’s Strength Become A Painful Problem?

Titanium is remarkable metal. It’s lightweight, strong, can be shined to a stunning polish, and its quite versatile. Its aerospace applications helped us reach new heights, and in industrial settings it offers extensive assurance and resistance.

These qualities have also made titanium a substance that’s readily recognized by consumers, especially those in the market for a tough, long-lasting wedding band. Titanium wedding bands and rings are a popular choice for couples, but the properties that usually sell them on the choice can also create a serious problem when the unexpected happens.

Titanium Is Just Too Tough
As reported by a number of emergency room doctors, titanium rings can become a major obstacle when it comes to urgently treating a patient. Due primarily to strength, titanium rings are much harder to remove from a patient’s swollen or injured finger. In addition to causing pain as a finger becomes inflamed, the loss of circulation can lead to tissue death and serious lasting damage.

Unlike silver or gold rings, which emergency rooms can usually snip off a patient’s finger without difficulty, titanium is just too tough for a conventional ring cutter. Although commercial pure titanium is softer and easier to cut than aircraft grade titanium, both alloys have added hazard to the already difficult job of emergency room doctors and nurses.

Conventional Clippers Won’t Do The Job
There are methods for removing rings without cutting them, including lubrication, elevation, and various techniques using plastic, gauze and string. However, when a swollen fingers cannot be manipulated in this way, or in the case of burns and critical situations when the ring must be removed promptly, the best solution appears to be keeping a pair of bolt cutters, which are increasingly among the range of medical tools maintained at hospitals and clinics for this very purpose. Even after a titanium ring is successfully snipped with a pair of bolt cutters, there is still the problem and bending and stretching the ring to fully remove it from a patient’s hand.

Strictly Industrial Alloys
Some may see this problem as an opportunity to create a better ring cutter, made specifically for extra tough rings, but others have said that titanium is better used for aerospace equipment and industrial fasteners and not for jewelry. Considering the popularity of gold and silver ring alternatives, titanium may not be the only source of trouble in such cases. Recently, tungsten carbide rings have also grown in popularity. And as anyone familiar with that metal can tell you, bolt cutters may not do the job of easily removing a ring made from that material.

What are your thoughts on using ultra tough, industrial metals as commercial jewelry? Have you ever had an issue with a titanium or tungsten carbide piece that you own? Tell us what you think about this increasingly common problem in the comments.

Medical Device Manufacturers Use Robots For Speed, Safety, And Cleanliness

Robotic equipment in medical device production lines allows companies to maintain high standards of cleanliness, worker safety, product consistency, and speed. From heart valves to artificial joints to surgical equipment, robots increasingly play an integral role in medical device manufacturing.

Robots Limit Biological Contamination

Manufacturing facilities have long contended with the contamination issues introduced by human workers. Robots allow for the removal of the human element from many production areas. In addition to maintaining sanitary environments, robotic installations have aided manufacturers during the coronavirus pandemic. The CEO of MICRO said that greater integration of robots in workflows helped to limit human-to-human contact among workers.

Precise And Consistent Results

On top of sanitation, medical devices require high degrees of precision. Robots are capable of extreme dexterity that a human worker cannot replicate with consistency. Medical device companies draw upon the robotic developments pioneered by the electronic and automotive industry that turned to robots to build miniature components. New production processes for building artificial heart valves have incorporated small robots that perform highly detailed work on small parts with repeatable accuracy.

Elimination Of Workplace Sharps Hazards

A multitude of medical devices and tools involve very sharp edges. Fabrication of these instruments historically exposed workers to the risk of serious cuts. The installation of robots to grind, deburr, and package medical sharps reduces risks of worker injury. Workers focus instead on monitoring operations while robots produce precision goods at speeds beyond what human workers could achieve.

Tecomet Inc. in Boulder, Colorado, is in the middle of expanding operations. In addition to hiring more workers, the company will add another 25 machines, including robotic systems, to its new facility. Longer-term, the company anticipates that it will manufacture robots for clients operating cleanroom facilities at hospitals.

In your experience, how has robotic equipment overcome production challenges or expanded opportunities for new business?

More Flexible Electronic Manufacturing Means Better Medical Monitoring

To fit more reliably and comfortably when worn, wearable electronics must be flexible while retaining their ability to collect and communicate data. Conventional sensors and other electronic components, even when made very small, don’t often offer these attributes, which can limit their use as medical devices. A new additive manufacturing method from researchers at Harvard University’s Wyss Institute for Biologically Inspired Engineering makes it possible to create useful monitoring electronics that fit more comfortable and move naturally when worn directly on the skin.

Hybrid 3D Printing

Through a process that the researchers refer to as hybrid 3D printing, electronically conductive inks can be incorporated into wearable devices that are not only soft and flexible, and therefore comfortable to wear, but can also be stretched and still perform reliably. The conductive ink is made from thermoplastic polyurethane (TPU) and contains electrodes, which can be layered with a soft, flexible substrate through an additive manufacturing process. As the ink solidifies, the result is a conductive, highly flexible, and fully functional circuit that can be used for a range of medical needs.

Custom Fit For The Patient And Diagnosis 

Since these soft sensors can be printed to just about any shape, and with the position of the conductive features determined during the manufacturing process, it’s possible to create medical sensory devices that fit the patient as well as the specific data to be collected. Researchers are able to collect information from a wearer’s movement or from the application of pressure and easily read the resulting data in a number of ways.

The hybrid 3d printing process has been noted as significant for the flexible and versatile devices it yields, as well as its relative low cost. While the resulting products are currently in the prototype stage, researchers have called this a first step in creating robust and affordable wearable electronics that are also comfortable and customized.

New Surgical Glue Could Render Stitches And Sutures Obsolete

When wounds are quickly and securely closed following injury, healing is faster, risks of infection are minimized, and more serious sustained injury can be prevented. A new type of surgical glue has been created to do that in a fast-acting and reliable manner. It may even change first aid and medical response procedures at car accidents, in combat zones, and at emergency sites.

Fast Forming For Better Wound Healing

MeTro behaves like a silicone sealant, much like those used to create a water seal in bathrooms and other household applications, but it works even faster. Once administered to human tissue, MeTro rapidly forms to gel-like thickness and serves to seal a wound. This action occurs as highly elastic proteins and light sensitive molecules are set after being exposed to UV light. The gel takes just 60 seconds to thicken and solidify, which is vital to blocking out bacteria in urgent situations.

Modifiable For Recovery Times

While MeTro securely remains in contact with the tissue to which it’s applied, it retains some elasticity so it moves with the patient and prevents wounds from reopening. The treatment can also be modified with a degrading enzyme that determines how soon MeTro will begin to breakdown. Whether sealing is required for minutes or months, the gel can be catered to appropriate recovery times.

For Use On Difficult To Treat Sites

Northeastern University and Australia’s University of Sydney Researchers responsible for creating MeTro have also shown how it can be used on treatment sites that are otherwise difficult to seal due to exposure to bodily fluids and natural expansion and contraction. The substance shows potential for use on vital areas that are challenging to stitch, suture, or bandage, such as internal organs like the lungs and heart.
