KMG-12/22: THE ADAPTIVE KERRISON INSTRUMENT
KMG-12/22 is the name of the Kerrsion instrument with interchangeable working ends developed by the Kammerer Medical Group. The innovative sliding shaft instrument is an efficiency booster.
Instead of many variants for all cases, there are only two to three handles on the tray and working ends in all variants sterilely packed in the cupboard. Depending on the intervention and thus the number of sliding shaft instruments in the set, this saves at least 50% of the set costs. Since there is no need to keep entire instruments in a backup tray, but only working ends, the savings for backup instruments amount to more than 75%.
Space and Cleaning Efficiency
provides for overview in sterile boxes and trays due to the elimination of many sliding shaft instruments in favor of only two or three handles. The weight saved is not only noticeable when lifted, but above all when it comes to saving heat during sterilization.
Use and cleaning take their toll on instruments, especially cutting ones. The instruments age with each processing, even if they have not been used. With the KMG-12/22, the handle can remain in the reprocessing circle for much longer and can be used again and again with new, sharp working ends.
Worn or aged instruments no longer need to be disposed of entirely (200 g stainless steel). With the KMG-12/22, only the working ends are discarded (15 g stainless steel).
In conventional sliding shaft instruments, the material represents a compromise between durability concerning reprocessing and the purpose of the working end. By separating the handle from the working end, we can independently optimize both: working ends made of harder stainless steel for cutting instruments, made of cost-effective plastic for clamping instruments, etc.
Advantages for the course of the operation
The most important advantage for rongeurs (gauges) and punches is that there are always new sharp working ends at hand. For all types of instruments, rarely used sizes and geometries can also be provided, which are not normally found in the trays.
Working ends are “made of one piece”, that is top and bottom are inseparably connected. This makes the change easy and quick and prevents incorrect combinations of top and bottom. Once the working end has been inserted, it automatically locks into the working position by pressing the handle – no fiddly locking, no risk of the working end coming loose during use.
About Kammerer Medical Group
Kammerer Medical has been manufacturing surgical instruments and instrument sets since 2000, primarily for the insertion of implants (spine, hip, knee, shoulder). A special process is used to bond silicone and stainless steel in such a way that they remain gap-free and therefore biologically safe even after hundreds of reprocessing cycles with cleaning agents and steam sterilization. A fully digitalized quality and risk management system enables complete documentation of the manufacturing process. Together with cleaning and ageing validations, this facilitates smooth approval of the instruments in accordance with the high regulatory requirements for medical technology. In a major growth step in 2023, the Kammerer Medical Group will triple its capacity in its new production and office building at the Stockach site.
