Compression Springs: 

The most common type of spring used in the medical industry, typically made from a single coil of wire and are used in applications such as surgical instruments, orthodontic appliances, and blood pressure cuffs.

A compression spring exerts a force when it is compressed. It is typically made from a long, thin wire that is coiled in a helical shape, with two open ends. When a force is applied to the ends of the spring, the coils are pushed together, creating a force that pushes the ends in the opposite direction. They can be designed to have a constant spring rate, meaning the force will remain consistent over the entire range of compression, or a variable spring rate, meaning the force will change as the spring is compressed. Additionally, compression springs can be designed to have a specific load or compression range depending on the application.

Extension Springs:

Exerts a force when it is stretched or extended. It is typically made from a long, thin wire that is coiled in a helical shape, with two hooks or loops on either end. When the spring is extended, the coils are pulled apart, creating a force that pushes the hooks or loops in the opposite direction. They can be designed to have a constant spring rate, meaning the force will remain consistent over the entire range of travel, or a variable spring rate, meaning the force will change as the spring is extended. Additionally, extension springs can be designed to have a specific load or travel range depending on the application.

Torsion Springs: Springs that are designed to store rotational energy and are used in applications such as surgical instruments and medical devices. A torsion spring exerts a rotational force when it is twisted or torqued. It is typically made from a long, thin wire that is coiled in a helical shape, with one end attached to a stationary object and the other end attached to a rotating object. When a force is applied to the end of the spring, the coils are twisted, creating a force that pushes the ends in the opposite direction. They can be designed to have a constant spring rate, meaning the force will remain consistent over the entire range of rotation, or a variable spring rate, meaning the force will change as the spring is twisted.

 

Additionally, torsion springs can be designed to have a specific load or torque range depending on the application. The most common shapes of torsion springs are single-bodied, double-bodied and tapered. Torsion springs can be designed to operate in both clockwise and counterclockwise directions. They are commonly used in applications such as gears, pulleys, levers, cranks, and other mechanisms that require a rotational force.


Constant Force Springs: These springs provide a consistent force over a specific range of motion and are used in applications such as medical devices, instruments and orthodontic appliances

Wire Forms: Complex spring-like structures that can be customized to specific shapes, sizes and dimensions, and are used in applications such as medical devices and surgical instruments.

Flat Springs: Flat strips of metal, which are bent or formed into a spring-like shape, and are used in medical devices such as surgical instruments.

Micro Springs: Miniature springs that are used in medical devices that require a small spring force, such as implantable devices and diagnostic equipment.

Wave Springs: These are a type of compression spring that consists of a wave-like shape, they offer a reduced solid height and are used in medical devices such as surgical instruments.
