These days surgical Instruments are made from a variety of materials including composites, plastics, titanium, and (the more traditional;) stainless steel. Typically two types of stainless steel series are most commonly used for instruments manufacturing.
The Austenitic steel cannot be hardened through heat treatment. The 304 grade is the typical grade used for surgical instruments and is suited for items which require some malleability, that is, they can be pressed or formed into another shape without breaking the metal. Cannulas, retractors, probes, mallets, and spreaders are amongst some of the instruments that are traditionally manufactured through this series of steel.
The Martensitic steel are low carbon steel that can be hardened and tempered through heat treatment process. Due to the strength achieveable through hardening process, this series of steel is more suitable for instruments that require strength and tough cutting edges. Bone cutters, clamps, forceps, needle holders, and chisels are some of the instruments that are traditionally manufactured through the 410/420 grade of this series of steel.
In order to maintain high quality and repeatability for our products, we strive to perform all production processes in -house. And while there are hundreds of sub-processes and tasks that go into the manufacturing of our surgical instruments, following is a list of major processes that we perform in house.
Shear & Press Work (we import our own steel from Japan)
Each of the above processes comes with its own parameters which have to be tailored to the needs of each item in production and customer’s requests. The above list gives you a brief idea of what goes on behind making a quality product in our company. Making a surgical instrument is tough enough, making it in good quality is painstakingly tougher. And even though we make great disposable instruments, our main strength lies with manufacturing the best quality reusable instruments.
Weaseling out of things is important to learn. It's what separates us from the animals…except the weasel. You know, the one with all the well meaning rules that don't work out in real life, uh, Christianity.
Lisa, vampires are make-believe, like elves, gremlins, and Eskimos. We started out like Romeo and Juliet, but it ended up in tragedy. Attempted murder? Now honestly, what is that? Do they give a Nobel Prize for attempted chemistry? Get ready, skanks! It’s time for the truth train! Books are useless! I only ever read one book, “To Kill A Mockingbird,” and it gave me absolutely no insight on how to kill mockingbirds! Sure it taught me not to judge a man by the color of his skin…but what good does *that* do me?
No children have ever meddled with the Republican Party and lived to tell about it. The lesson is, never try. Oh, so they have Internet on computers now.
That sounded like a prayer. A prayer in a public school. God has no place within these walls, just like facts don’t have a place within an organized religion. Son, a woman is like a beer. They smell good, they look good, you’d step over your own mother just to get one! But you can’t stop at one. You wanna drink another woman! The Internet King? I wonder if he could provide faster nudity.
Good morning, oh in case i don't see you, good afternoon, good evening and goodnight. excuse me, i'd like to ask you a few questions. we're going for a ride on the information super highway. Here she comes to wreck the day. here she comes to wreck the day. alrighty then kinda hot in these rhinos. we're going for a ride on the information super highway.
Books are useless! I only ever read one book, “To Kill A Mockingbird,” and it gave me absolutely no insight on how to kill mockingbirds! Sure it taught me not to judge a man by the color of his skin…but what good does *that* do me? I’m a Spalding Gray in a Rick Dees world. You don’t win friends with salad. The Internet King? I wonder if he could provide faster nudity.
Good news, everyone! There's a report on TV with some very bad news! Actually, that's still true. We'll need to have a look inside you with this camera.
There’s one way and only one way to determine if an animal is intelligent. Dissect its brain! It’s a T. It goes “tuh”. Anyone who laughs is a communist! Morbo will now introduce tonight’s candidates… Morbo’s good friend, Richard Nixon.
