The Power of a Mark

unique device identification

CensiMark is a proprietary surgical instrument marking barcode that is applied by embedding a 2-D electro-chemical mark below an instrument’s passivation layer. This electro–chemical marking process (ECMP) applies a guaranteed corrosion-free mark to the instrument and does not alter the surface like etching or engraving. With two different sizes of instrument marks, CensiMark can be applied to all different types of assets, including flexible scopes, neurosurgery and cardiovascular instruments.

The ability to mark surgical instruments with unique device identification is the key to unlocking your department’s ability to handle: 

  • Faster tray turnaround times mandated to increase operating room efficiency
  • Larger and more complicated tray sets needing to be reprocessed
  • The scope of regulatory requirements constantly expanding
  • The number of staff competencies increasing and becoming more complex
  • The lack of process visibility for all perioperative stakeholders dependent on timely reprocessing

Censis Technologies also offers a comprehensive instrument marking service that provides a rapid deployment option for applying CensiMark instrument-specific barcodes to a facility’s existing instrument inventory. This optional service provides facilities a committed team of experienced industry professionals that arrives on-site to mark the maximum number of instruments at a facility with minimum disruption to daily workflow.

ECMP: Remarkable Technology

The electro-chemical marking process (ECMP) is a key component of the CensiMark proprietary solution. ECMP applies a 2-D matrix barcode mark on the surface of an instrument without affecting the instrument’s passivation layer. Using a marking wand with the marking head dipped in a non-toxic electrolyte solution, a low-voltage current is passed through the wand to a stencil placed over the area of the instrument intended to be marked. In a few seconds, an imprint of the stencil is transferred to the instrument. This method of instrument marking is a safe and easy process, with the resulting mark typically lasting the lifetime of the instrument.

The CensiMark solution also includes a high quality stencil product, that helps to ensure the effectiveness and success of the marking process, as well as promote the longevity of a mark. Each individual stencil bares a unique barcode designed specifically for surgical instrument tracking, so when applied, an individual instrument can be accurately and continuously tracked within a facility.

The Benefits of ECMP

  • It does not damage the instrument surface.
  • The process is a simple and only takes seconds to complete.
  • The required materials are non-toxic and hospital safe.
  • The resulting mark does not promote bio-burden buildup, and is corrosion resistant.
  • When the process is properly performed, the resulting mark typically lasts the life of the instrument
  • This method allows marks to be applied to small, confined areas, as well as to rounded surfaces.
  • There is little or no maintenance required for the marking unit.
  • The method is more cost effective than other marking options.

Impact on Tray Accuracy

It is not unusual for surgical assets to “migrate” from tray to tray as they move through the reprocessing loop. This reality, combined with the growing size and number of instruments in many of today’s surgical sets, makes assembling trays accurately to comply with a specific configuration a complex task.  The use of electronic count sheets helps with documentation and provides easy access to assembly instructions, and acceptable substitutions, but adding the ability to “scan” assets during the assembly process can dramatically impact tray accuracy and technician efficiency. The combination of the CensiTrac software with the CensiMark solution helps to ensure instrument sets have the precise instrument type and quantities required for a specific configuration by alerting the user if items do not belong or if the quantity has been met.

Impact on Maintenance and Repair Costs

It makes sense that it is more cost effective to send instrumentation out for maintenance based on number of uses, rather than sending items out on a schedule, whether maintenance is due or not.  Combining the CensiMark solution with the CensiTrac system allows the software to track the number of times an individual instrument goes through the reprocessing loop.  By alerting staff assembling trays when maintenance is due on an individual asset based on actual usage, facilities are able to reduce annual maintenance costs.

Ability to Link Specific Instruments to a Patient Case

The ability to identify and possibly isolate which surgical assets were used in a specific patient case is important when investigating surgical site infections (SSIs) and other post procedural complications.  Because surgical instruments can “migrate” from tray to tray as they move through the reprocessing loop, and go in and out of a facility for maintenance, determining which assets were used on which patient becomes possible with the CensiMark solution.  When individually marked instruments are scanned as trays are assembled, and then those trays are scanned into cases in the OR, the CensiTrac software is able to capture and track which individual assets where used in which cases.

Impact on Lost or Missing Assets

Using the CensiMark solution to mark and identify surgical assets means that the last scanned location of every individual marked asset, (including but not limited to instruments, peel packs, and endoscopes) is tracked.  Having individual asset location information in just a few clicks enables facilities to find assets, or determine when assets have gone missing in a much more efficient and effective manner.
