Surgeons Using Robots
Robotic devices help surgeons perform operations with
previously unachievable precision. However, combining
functionality into a single machine requires complex
electronic systems, and designers are under pressure
to deliver the best possible performance, along with low
latency, in the smallest possible package. This becomes
even more significant when the time comes to connect
the robot to the outside world.
Molex Compact Robotic Connectors (CRCs) provide
a compact solution for small robotics where durability
meets clean-room aesthetics. The connector system
was designed to meet various medical and clean-
room applications' space savings and shielding
requirements. Furthermore, Molex's rugged, high-
density Versabeam Array MT cable assemblies
are designed to exceed market requirements for
high-bandwidth medical applications. Adapted
from the Molex traditional data communication and
telecommunication inter-chassis connections, the
interconnect system has proved valuable in robotic-
assist surgical applications and picture archival
communications systems (PACS) applications. When
space constraints are an issue, hybrid designs can
reduce the number of connectors needed and provide
easy installation for most applications. The use of
hybrid connectivity also can bridge the transition from
electrical to optical by combining fiber and copper in a
single connector housing.
Multifunctional Cardiovascular Devices
In the quest to develop effective methods of treating
cardiovascular disease, doctors are turning to
innovative energy sources and advanced technologies
to guide diagnosis, treatment, and monitoring after
treatment. Microwaves, cryo-energy. and even lasers
are providing physicians with the ability to treat
patients using minimally invasive techniques that
deliver the best clinical outcomes.
The integration of multiple modalities in a single catheter
brings with it considerable complexity. For example, the
high number of wires and cables required means that
the connectors need to feature high contact densities
while also delivering superior performance.
Molex's compact 433MHz ISM Antenna delivers more
space savings and higher radiation efficiency (>50 to
>56 percent, 50mm to 300mm cable length) for its
size (90.00mm by 40.00mm). The Molex 868MHz and
915MHz ISM Antennas with MobliquA
™
Technology
enable significant antenna volume reduction while
eliminating the need for expensive circuits and
the frequency tuning required for ground plane-
dependence issues. Additionally, cardiovascular device
applications require both power and a signal. Molex
has been at the forefront with connectors such as the
Mini-Fit Connector Family, which offers up to 8.5A
with a 3.00mm pitch, delivering power in a compact
package. Because reliability is crucial in cardiovascular
devices, Molex offers the Micro-Fit TPA Connector
Family, which helps prevent failure in end products by
providing terminal position assurance (TPA).
Conclusion
Technological developments in wireless data
transmission and the miniaturization of components
and connectors have enabled more effective remote
healthcare in drug delivery and minimally invasive
robotic surgery. Whether it is wearable devices
engineered to provide a drug-delivery solution
or robotics helping surgeons perform precision
operations. Molex's vast selection of interconnects
and high-performance compact antennas are leading
the way in helping to transform the healthcare industry
and enable MedTech's vision to become a reality and
deliver the best clinical outcomes. n
