Tumblast systems deburr joint prostheses

Perfect surfaces for a patient’s health

In most cases, joint prostheses will remain permanently in the body as implants, substituting a damaged joint completely or partially. Most known are the artificial hip joints. Here it is very important that the joint prostheses, mostly made of a ceramic-plastic mixture with titanium alloy, will optimally grow into the body’s own tissue. This will happen once newly formed bony substance firmly encloses the prostheses. This integration into the bone requires not only precise incorporation of the prosthesis into the bone bed but also the respective surface properties.

Surface treatment of joint prostheses

In the course of the years, SIGG Strahltechnik has built up a great deal of expertise in the surface treatment of joint prostheses. Prior to the alloying, the cast joint prostheses must be deburred which is accomplished in tumblast systems by SIGG Strahltechnik. The automatable tumblast systems are optimized for the surface treatment of work pieces that allow handling like bulk material. One of many examples is the roughening of joint prostheses shafts.

Documentation of the production steps

In deburring processes of joint prosthesis, aside from a perfect surface, also the documentation of the production steps, as required by law, must be taken into account. Here the issue of purity is paramount in order not to provoke any damaging consequences for the patient’s health. Quality at the highest level is obligatory as especially in the medical sector substantial claims for damages may be at risk. That is why all surface results will be additionally examined under the microscope as well as with roughness measuring devices. At the SIGG testing laboratory not only the adequate technology will be scrutinized but also suitable blasting abrasives and grinding abrasives will be tested.
