Custom medical enclosure for a control unit

Author : Justin Buch is Operations Director for Cipher Surgical and Dan Smalley is Enclosure Design Manager

Cipher Surgical needed to find a partner with knowledge in enclosure design for its new OpClear control unit that was destined for use in hospital operating theatres worldwide.

It selected CamdenBoss, a company with the expertise and technology to deliver against a very stringent and exacting set of requirements. Justin Buch, Operations Director for Cipher Surgical and Dan Smalley, Enclosure Design Manager at CamdenBoss take up the story.

A frustration for most laparoscopic surgeons across the world is that vision can be reduced due to the laparoscope’s lens becoming misted up or coved in blood, peritoneal fluid or particulate matter. OpClear releases a quick pulse of CO2 and wash fluid across the ’scope lens, sweeping and washing away any particulate matter. The OpClear control unit’s intelligent design also removes and prevents misting so surgeons can maintain a clear view during the whole procedure, maintaining workflow and concentration, enhancing patient safety and banishing the frustration of working with reduced vision or having to stop.

Designed for use in hospital operating theatres worldwide, the OpClear control unit needed to meet the very strict requirements of electrical safety – ISO 60601-1 – and EMC requirements ISO 60601-1-2 as well as meeting IC (Industry Canada) and US FCC (Federal Communications Commission) emissions standards. This was further complicated by the RFID system employed in the OpClear unit that allows automatic recognition of any product attached to the control unit as well as the usability aspects laid out in ISO 60601-1-6.

Cipher Surgical’s hunt for a design partner with knowledge in enclosure design and manufacture led them to CamdenBoss, who helped develop a case that met the exacting requirements of medical environments without compromising on the design for ease of manufacturing and serviceability.

Justin Buch commented that CamdenBoss were chosen due to their expertise in the design and manufacture of bespoke enclosures for medical instruments and, in partnership, Cipher Surgical has been able to create a new system that meets the technical requirements, maintain great aesthetics and achieve a product that is easy to assemble. CamdenBoss is also a supplier of choice to manufacture the enclosure parts for their control in material selection and manufacturing expertise for products used in such demanding conditions.

He added that the CamdenBoss design team worked well in the overall project comprising Cipher Surgical and its other development and manufacturing partners, helping it achieve first time passes on all aspects of the control unit testing against the very demanding standards. CamdenBoss’s design team also attended cross-partner company working meetings to discuss the system design and contributed to resolution of issues as they arose through the development cycle. The team’s adaptable approach also contributed to controlling project schedules for a timely outcome.

Dan Smalley commented, CamdenBoss worked on the enclosure design from the outset and produced a variety of concept designs. From there, the construction of the case was developed paying special attention to ensuring that the enclosures were easy to populate with components and also straightforward to assemble. The OpClear unit is a complicated piece of equipment with many interconnecting parts so CamdenBoss designed and prototyped the enclosures in a way that allowed fast assembly, met the IP rating and other standards and resulted in an aesthetically pleasing unit. Volume production is now in full swing.
