Magnetic solutions for high-tech in medical and dental technology

Invisible helpers in action: magnets in medical technology

With magnetic precision: Magnets are of central importance in modern medical technology and are used in a wide range of applications and devices.

Their unique physical properties - in particular their ability to act without contact, their reliability and their ability to be integrated into compact designs - make them an indispensable component of many medical technology solutions.

Magnets offer a wide range of applications in medical technology - from diagnostic imaging and sensor technology to therapeutic solutions and implants.

They enable compact, reliable and often maintenance-free components that meet the industry's high safety and hygiene standards. Thanks to the continuous further development of magnetic materials and production technologies, new areas of application are constantly opening up - and offer innovations for modern, effective and patient-orientated medical technology.

Different types of magnets can be considered for medical technology applications depending on the area of use. Factors such as magnetic strength, temperature resistance, corrosion protection and biocompatibility play an important role.
Magnets therefore form the basis of many innovative applications in medical technology.

Below you will find an overview of how magnets can be used in medical technology:

Sensor technology and positioning
Magnets are often used in conjunction with magnetic sensors to precisely detect movements, positions or angles in medical devices.

Control and locking
Magnets can function as part of locking or interlocking systems - for example, in medical device housings as magnetic switches or holding mechanisms, or in surgical lamps and examination lights for flexible and safe positioning.

Implants and prostheses
Magnets are also frequently used directly in or on the body, for example to attach dental prostheses or hearing systems (e.g. cochlear implants)

Laboratory technology and diagnostics
In laboratory medicine, magnets are used for automation and to increase efficiency, for example magnetic stirrers for the contactless mixing of liquids or magnetic separation for sample preparation. Magnetic holders are also frequently used to manufacture prostheses.

Rehabilitation and physiotherapy equipment
Magnets are used in rehabilitation or fitness equipment to generate and regulate training resistance. Magnetic principles also enable micromotors and drives in highly compact medical devices such as insulin pumps and inhalation devices or in minimally invasive surgical tools.

Contactless energy and data transmission
Magnets and magnetic fields play a role in inductive coupling - for example: for wireless charging of implantable devices or for data transmission in sensitive electronics inside the body.

Magnetic power for health: how we support medical technology

Denture cleaning device with holding magnet

Compact cleaning device, particularly suitable for cleaning removable dental restorations using rotating cleaning pins. High time saving thanks to effective and automated cleaning process compared to manual methods. Effective and strong holding magnet inside.

The magnetic control of cannulas

The positioning of hollow needles is an advanced procedure in medical technology that enables precise, minimally invasive interventions. Magnetic fields are used to navigate the cannula (needle) and track its position in the body in real time.

Magnetic base and split-cast systems for dental technology

A splitcast is a two-part base system that connects plaster models precisely and stably to a milling base using magnets or moulds. It makes it possible to fix models in place during processing and at the same time keep them mobile or remove them at any time.

Magnetic system for bioresonance therapy devices

High-quality ferrite magnets are used as an integral part of a bioresonance device. These are used to generate a homogeneous, static magnetic field and thus intensify and regulate the treatment.

Magnetic fixation systems in the medical sector

These highly specialised magnetic safety latches are used to protect patients in care or hospital beds from falling or endangering themselves. These magnetic systems must be corrosion-resistant and temperature-resistant (e.g. washable at 95 °C), as well as tamper-proof.
The system consists of three components:
The base: A stable lower part that is firmly connected to the fixing strap or the bed frame
The lock head: Is placed on the base and engages mechanically
The magnetic key: Strong permanent magnet that releases the internal locking mechanism as soon as it is placed on the lock head from the outside.
Without the matching (magnetic) key, the connection cannot be released by pulling or pushing

Magnetic surgical instruments

An intraocular magnet is a specialised surgical instrument used in ophthalmology. This fine, pen-shaped instrument with a very thin magnetic tip is used as a hand magnet to precisely and safely remove ferromagnetic foreign bodies from inside the eye. It must be biocompatible and sterilisable (high heat / pressure).

Magnets for transport trolleys in the medical sector

In modern medical technology, logistics solutions made of aluminium and stainless steel rely on highly resistant samarium-cobalt (SmCo) magnets in protective, tightly welded stainless steel housings. These special systems are explicitly resistant to washing tunnels and can withstand the loads in automatic washing systems or sterilisation tunnels. In sterile goods transport trolleys, they serve as reliable door holders to keep the fronts safely open during loading or cleaning. They also act as magnetic centring aids when efficiently coupling several trolleys to form a trolley train.
