CD+ Labs System Benefits

The CD+ Labs System sets a new standard of procedural control. The fully integrated procedural and stabilization system provides precisely controlled retraction at the operative site. The CD+Labs System allows researchers to operate independently, eliminating the requirement for an assistant or improvised assistive devices. The system removes the complexities and distractions of improvised set-ups, allowing the researcher to focus full attention on the surgical procedure.

  • Eliminates need for assistance or improvised assistive device
  • Reduces setup and procedure time
  • Provides superior control
  • Improves visualization

The CD+ Labs System is unlike any other, providing glove-friendly, operative simplicity. With the touch of the finger, the system can be set, released and manipulated. This is made possible by patented mechanisms in the fixators which use rare earth magnets and push-button spring locks to form a fully integrated small-animal procedure system. All system components are compatible with standard lab instrument cleaning systems.

The System Components

Fixators – the heart of the system

Fixators hold retractors. They contain rare earth magnets that attach anywhere on the animal table. A push-button operates multi-level locking jaws that grip wires or elastomers firmly. They can be adjusted linearly or rotationally with finger-tip release. Complete depression of the push-button allows for adjustment. Fixators can also lock onto other lab components that require stabilization in the surgical setting, such as neurological or rectal probes or anesthesia delivery systems. The magnetic field is well controlled within the fixator to minimize interference with sensitive instrumentation. In fact, at a distance of just a few centimeters the effects of these small but powerful magnets are completely masked by Earth’s ever-present magnetic field.

Animal Tables

Animal tables are made of ferro-magnetic stainless steel and incorporate a window for compatibility with body temperature maintenance systems. Tables are available in a variety of sizes and shapes to suit a range of animals.


CD+ Labs System retractor wires are formed from light, flexible stainless steel. This simple approach produces an economical instrument that performs its job with minimal clutter, while providing superb control and feel. Retractor wires can either be used on their own to retract or manipulate tissue or retractor tips can be fitted to provide a wide range of retractor styles. Retractor wires engage and lock into the fixator jaws at the desired elevation allowing both linear and rotational adjustment over the entire length of the wire. One end of the wire is formed in a loop to provide grip for a gloved hand, and the business end is formed into a right angle hook that can retract on its own or lock to a range of retractor tips. The wires can also be re-formed to create restraints or engage other lab apparatus that need to be secured in the surgical field. Wires are available in 10 and 14 cm lengths for mouse and rat procedures. Retractor tip widths range from 1 mm to 7.5 mm, plus a single point, sharp tissue hook. Each tip can be locked onto a wire for static retraction, or affixed to an elastomer to form a dynamic retractor.

Rare Earth Magnets

Sometimes an innovation is so intuitive it quickly displaces all predecessors. 

The CD+Labs System and its use of rare earth magnets is just such an innovation. Intuitive and purposeful, once adopted it leaves researchers reluctant to consider procedures without it. The reduced set-up time, superb control and the improved visualization eliminate the awkwardness of earlier methods, allowing researchers to focus their full attention on the delicate procedure at hand.
