A new laser navigation system for image guided medical procedures

Maxon brushless DC motors, gearheads and encoders are at work in a laser system for CT-guided procedures.

Doctors rely upon high-resolution CT images, for example, to guide biopsies, make diagnoses or for pain relief therapies. After identifying an area for biopsy, surgeons ascertain how to reach the area, where to place the needle tip, what angle to follow and how to minimise damage to healthy tissue. To combat these issues with pin-point technology, a German company designed an automated laser-guided system consisting of a ceiling mounted arc-shaped rail on which a motorised laser positioning unit is affixed. The laser guides the entry point, depth and angle for a needle that is 0.7mm thin.

A brushless maxon DC motor combination, selected for the small size and reliability of operation, meticulously drives the unit on the arc’s rail, which holds the rotary laser. The brushless flat EC motor with a diameter of 45mm is fitted with a planetary gearhead and MR Encoder. Two more brushless maxon DC motors control the rotation of the laser mirrors, the EC-max 16 fitted with a GP 16A planetary gearhead and MR encoder. These brushless DC motors allow for exact positioning of the laser beam and are controlled using three EPOS2 Modules.

Innovation, DC motor technology and the medical industry.

The number of worldwide medical patents filed in 2015 was more than twelve-thousand. The term “innovation” certainly applies to this industry.

In the field of medical technology, surgeon’s tools and machines are becoming smaller. Robotic assistance is commonplace in prostate surgeries. Minimally invasive surgery, surgical tools that can reach sensitive and in-depth parts of the brain once considered too high-risk, are being explored. Machines that aid faster patient recovery times and robots that assist in rehabilitation. Maxon motors are at the forefront of medical technology, working along-side Universities, start-ups and multi-national corporations. Medical applications that have maxon DC motor technology and expertise include the da Vinci Robot, wheelchairs that can climb stairs, aortic pumps for heart patients, implantable dosage systems, robotic exoskeletons, surgical tools and prosthetics.

Obsolescence equals Opportunity.

RE50 motor for industrial automation and robotics.

The phase out of an old DC motor and the realisation of power, weight and price advantages of new designs, widens customer device application areas.

The maxon 2260 series of brushed DC motors was for decades an industry standard, providing reliable high torque performance. Because of its quality and longevity it was not considered for replacement or design-out until they were informed via maxon motor’s discontinuation policy procedures of its pending obsolescence. The initial disappointment and concern was quickly turned to relief after maxon initiated application engineer contact to advise customers about the available replacement possibilities. The maxon DC 2260 motor featured a continuous power rating of 80W and 330mNm of torque from 60mm diameter and 126mm length. The motor had a mass of 1300g. The typical replacement motor for the 2260 is the maxon RE50. This new motor features a continuous power rating of 200W and 450mNm from a 50mm diameter and 108mm length. What’s more, there are higher speed capabilities, a 200g weight reduction and yes, it is less expensive. In one instance the performance increase has given a customer’s product increased versatility and higher sales. The typical response being “why didn’t we do this earlier?!”. maxon motor provide support through the products entire lifecycle and as motor technology advances the end applications evolve also.

New DC servo gear motor combinations

Complex processing applications requiring human interaction require absolute precision to ensure operator safety. New zero backlash brushless DC servo gear motors with absolute encoder combinations supply the solution.

When a mineral processing company required an automation process involving high torque levels in close proximity to the machinery operator, new product thinking was required. The heavy equipment being moved generates considerable inertia that would need to hold under brake tension. Position control of the load requires encoder feedback on the brushless DC motor to compliment absolute encoder feedback on the load and zero backlash on the gearhead to ensure the unit is in the exact position that the control system thinks it is.

The solution pictured is the first assembled combination of a maxon 60mm 48V 400w brushless DC motor, 3 channel digital incremental encoder, 24V holding brake and 160:1 zero backlash gearhead. This new motor solution can hold a 400Nm load continuously and withstand shock loading on the output of up to 2200Nm. Speeds of up to 30rpm are capable from the unit and it is easily configured for use with servo amplifiers or position controllers having zero cogging or mechanical detents.

For further information on this new product combination or engineering assistance with complex applications please do not hesitate to contact our Sydney office. Ph. +61 2 9457 7477.
