Abrasive Waterjet Machine’s Role in Precision Cutting for Medical Equipments

As young technology that it is, the evolution of abrasive waterjet machines reached a point where they can already offer a substantial benefit to manufacturing firms that are catering to the production of in-demand and most sought after surgical instruments and a wide array of other medical applications. 

With their ability to hold positioning accuracy reaching to ±0.001″ and complemented by continuous technological breakthroughs in micronozzle production, a growing number of manufacturing firms in the medical instrument sphere now employ the use of waterjet machines to further strengthen their operations and productivity.

Contrary to public perception, it is not water that carries out the actual cutting work on industrial waterjet cutters. Rather, water acts as a delivery vehicle for the tiny abrasive particles such as garnet. They are being accelerated to supersonic speeds. This way they can deliver a highly productive cutting work by virtue of erosion, much in the same how a grinding process works.

Beneficial to Medical Manufacturers

Increased level of productivity is among the chief benefits a manufacturing firm is bound to enjoy if they will incorporate the use of abrasive waterjet machines in their operations. This is completely contrasting to other traditional metal-cutting methods we have. Water jet cutting substantially offers us a considerably higher rate of cutting speeds but requiring a lesser amount of time for setting things up. 

The waterjet process is seamless and a straight-forward one. As for the waterjet operator, he may only need to upload a drawing of the part together with all the specifics and required tolerances. The onboard software will then take on the calculation of tool paths. After this, it will carry out the cutting data. The convenience of setup and the rate of cutting speed is giving us good reasons why this qualifies as an excellent alternative method to using for prototyping applications and large component production runs.  

After some time that waterjet technology was first introduced to the world, there is no way that abrasive waterjet machines will be able to deliver tolerances, a requisite of many medical applications. 

This is not true anymore for parts that need tolerances below 0.002”. Even for work that requires a high level of precision, this material cutting method can deliver substantial benefit and does so by cutting finished near-net parts with the use of an ancillary process. This also applies to part geometries that go beyond the flat dimensions produced by abrasive water jet cutting, even though the recent progress of bevel-cutting nozzle accessories broadened the breadth of geometries that this material cutting method can produce outright.  

Compared to many other material cutting practices, an abrasive waterjet is a handful of key advantages. Laser discharge machining and laser technologies tend to produce heat-affected zones in and around the workpiece you are trying to cut. 

HAZ (heat-affected zones) induces surface hardening and in a way alters the  chemical attributes of the material. Abrasive waterjet is a qualified cold cutting process, and being such it offers users immunity from such effects. It is also an environmentally superior alternative as opposed to photo-chemical etching. Normally, this would be leaving behind a trail of hazardous or toxic waste materials.

Last, but not the least, abrasive waterjet machines would only apply a small amount of force on the material or the area you are trying to cut through. This allows for seamless and convenient cutting of delicate features that is otherwise very difficult, costly, or impossible to produce if you will only employ the use of traditional cutting methods.

The Importance of Lighting During the Coronavirus Pandemic

In the hopes to defeat the Covid-19 pandemic governments all over the world are prioritizing the supply of medical supplies, protective equipment, food essentials, and pharmaceuticals. Next to such are the other important sectors. However, one serious risk is being overlooked and taken for granted- it is the role of light.

lockdown street light

Artificial lights are very important in today’s time of crisis. With lights, we can get doing all the basic things we need to do. Most of all, functional lights play an important role in keeping test facilities, hospitals, highways, supermarkets, and distribution centers running both day and night.

The Role of Lighting in Today’s Crisis

Front Line

It is not only the visual property of lights that is making a huge difference today. Although not everyone realizes it, bit UV radiation plays a key role in disinfecting hospitals. Also, it utilized disinfecting police stations, factories, schools, offices, and post offices. For example, a UV-C radiation that comes with a wavelength of 254nm can break down the DNA of mold, bacteria, and viruses. It can even purify water and air.

Here are more ways on how lighting improves the quality of life, while adding essential value during this difficult time in our lives today.

Health at Home

With an overwhelming number of individuals who are now staying in their homes, the importance of light for their well-being and that of their family should never be underestimated. In fact, even before this crisis came to exist, almost 90% of our time was being spent inside with not enough daylight. Indeed, light is very essential to everyone’s health and well-being as it helps regulate our sleep-wake cycle.

In addition, it could help with people’s daily routine. A bright and functional light can keep us energized and enhance our concentration levels. On the other hand, warm light can help create a cozy atmosphere that helps unwind at night. Simply put, having the right type of light would make us feel, see, and function much better.

Food Security

There is one more unsung application of light and it is in food production. With artificial lights, it is possible to grow crops in many countries, thus reducing the distance and lessening the dependence on imports that could be carbon-hungry. Such is changing the way people farm. In today’s time, when the supply chains are tested, food security is most important.

Keeping the Streets Safe and Secure

The majority of pedestrians and drivers recognize the requirement for a well-lighted street. A good quality lighting for the streets can help reduce accidents and injuries by up to 30%. In addition, a well-lit street is also safer. Police officers can tell that proper lights can help prevent crime.

Light has so many benefits, although we do not realize all of them. But one thing is for sure, our lives have become so much better because of light. And during this trying time, we can just all be thankful that lights are available to help us in many ways.

What Important Role Does Water Jet Cutting Processes in Surgical Procedures?

Several sectors in our modern society have been enjoying the benefits of the waterjet cutting process for quite some time now. The vast majority of organizations that are involved in the manufacturing and fabricating space have seen the potential of waterjet cutting and have taken advantage of it for their various industrial cutting, cleaning and drilling requirements.

But today,  things are changing, taking a 360 degree turn for waterjet machines because the medical field has now found a place to make good use of it.  Waterjet technology applications can now be seen in medical rooms particularly in wound cleaning, dentistry, and many other surgical operations. Waterjet techniques, over the years, have evolved and developed to become what we now consider as a groundbreaking cutting tool. There are now many different types of application for this technology in medical surgery.

The water jet machine is going to be moved in a line to allow for the application of the pressure and the cut. If there is something about waterjet incision that can be considered as its key benefit, it would have to be its level of precision. Waterjet cutting precision is  high enough to the point that makes it comparable to the quality of cut that only laser cutter machines are capable of delivering. But the good thing about it is that waterjet incisions are not likely to bring about any kind of thermal damage to the tissues that are being separated and this is attributed to its coolant ability.  Add to this, waterjet machines can also clean and wash away blood. This takes away the need for an additional extra tool to help get the job done.

A great performing waterjet machining process will be highly dependent on the  water pressure coming out of the jet together with the skin’s elastic properties. The highest impact would be the initial impact itself and this can be achieved the moment that the waterjet hits the skin tissue. After which, the water can be expected to flow radially, which will inevitably reduce the impact of the jet.

Waterjet in surgical wound debridement

Amongst the most practical applications of waterjet technology in the medical world is its important role in surgical wound debridement. It also served as a good alternative for surgical excisional techniques applied primarily for burn wounds.  A study has shown that relevant waterjet technology can efficiently debride wounds from superficial partial thickness down to mid-dermal partial thickness wounds to help prepare the affected area for the subsequent Biobrane placement.

In 2007, a study about a particular brand of waterjet surgical tool was made and it made an in-depth review of how versatile the said equipment was when it comes to the treatment of deep and indeterminate neck and face burns. The very same study also made an important affirmation. The highly predictable depth of debridement is attainable by making some needed tweaks on the apparatus settings.

Waterjet Incision and Other Procedures

The integration of waterjet technology to a number of surgical procedures was first carried out in 1982 for resectioning procedure for liver. In the years that followed, it came to a point that it became fully recognized in various areas of surgical procedure.

Clinically speaking, this technology is utilized primarily for cutting soft tissues which would include liver tissues. It is also taken advantage of in experimental procedures involving spleen dissection, brain tissue, and kidney tissue. These tissues are cut at low water pressures, whereas bone and bone cement are cut at a much stronger, higher water pressures.

Conclusion

With a given surgical operation characteristics, a relevant mathematical  model can help an awful lot in calculating optimal operating conditions for debridement, surgical cutting or drilling.

Surgeons will be able to choose the right size of nozzle to use together with the right parameters for the waterjet instrument, from velocity, power, and finally pressure. The next step after this is the evaluation on the results of the study. This measure will help in creating a broad simulation model  for the surgical procedure to be done, like for instance Caesarian section procedure. 

When it comes to the water jet cutting machine process, there seems to be a lot to be hopeful about it. Not just in the medical world, but as of this writing further progress has been made about its use and application in many different areas of interest such as  aeronautics, manufacturing, and architecture. It is clear to see that this technology is ushering these sectors to further development and growth.
