Choosing Medical Springs

The History of Katy Spring

The history of companies is built by many short stories; some boring, some not. We’re going to try and tell the not-so-boring ones (in our humble opinion) about Katy Spring & Mfg., Inc.; a company in Katy Texas that started with a conversation that ended something like this; “Why not.”

These are the stories about Katy Spring, small bits of a bigger story that started in 1999. The stories are still unfolding new chapters every day, thanks to our wonderful customers. It’s written for our customers and future customers so that they can get to know our company, our employees, some historical background and philosophy a little better.

The stories are not told in chronological order. This blog is more of a “Readers Digest” about Katy Spring, written in whatever random order they appear. So, without further ado, let’s get started with the next read which is titled; “Choosing Medical Springs”

Picking a spring with the proper action, material, and feel can be critical to the success of a medical device.

Choosing or designing the right spring is especially critical when it comes to medical devices.

Springs can be used on various medical devises including; x-ray machines, bed lifts, and drug cabinet dispensers and surgical devises.

Here are some things to keep in mind when choosing the right design or spring.

Choose the right configuration;

  1. Compression Springs– for compression force.
  2. Extension Springs– for pulling forces.
  3. Torsion Springs– for torque forces.
  4. Flat Springs– for applications where the above will not work in the application.
  5. Wire can run as low as .003”, most spring coilers can manufacture starting at .007.”
  6. Material types for medical springs are many times stainless steel.  Carbon steel, generally has better spring properties, but is typically used is an environment that is non-corrosive or a non-sterile environment.

Other consideration;

Sometimes when testing a device, especially a medical tool using a spring, feel is important.  The spring manufacturer can assist with designing the feel desired in a medical device using a spring.

Additionally, spring manufacturers can assist with design and all the components of spring design including; spring ends, size envelope, weight of the spring, movement, trap and tolerances, cost-saving input, and much more.

There’s typically more than one solution to solving a spring problem.  Leave it to the spring experts to help guide medical designers in finding their unique solution.
