EPM MUELLER® modular hollowrasp with rasp shaft and sliding hammer with extra connection for pneumatic device



Modular Hollow Rasp
Advantage:

Producers of implants and distributors as compared to other products:

• Free design of the rasp surface, which makes it applicable for cemented and cement-free implants
• Depending on the rasp-philosophy of the user, a higher or lower permeability of liquids and solid materials into the inside of the rasp can be achieved. A change in the cutting geometry modifies the cutting or the compacting properties of the rasp.
• Retains the tried and tested implant system
• Increases the profit by using cost-effective instruments
• Significant competitive edge because of the uniqueness
• Increases the market share in the implant segment through new arguments for buying
• Quick and flexible adjustment of the rasp to the implant

Physicians:

Conventional rasp technology is "high impact surgery" which does not come up to the high technical standard in the other fields of endoprosthetics.

"Experts in the subject have hardly been able to understand for a long time that the highly developed technologies used for the production of prostheses are confronted with implantation techniques that seem to come from the stone-age. Thus, even today in most of the cases the preparation of the marrow area is still done by forming rasps that are driven into the sawn-off shaft of the thigh with the help of a heavy hammer.

• Better and easier handling
• Safty and axial rasping due the slite hammer of the impactor
• Less physical input for the operator
• A reduced risk potential for fractures
• An exact fit of the implants, higher precision
• A reduction of possible complications and a minimization of the FES-risk
• Easy grafting material gaining becouse of the modularity
• Easy cleaning becouse of the modularity
• No costly adaptation of the operational technology

Hospitals:

• Economic efficiency for hospitals:
• Avoids costly complications
• Reduces the cost-intensive time for operations
• Low investment costs

Patients:

• A low traumatizing effect
• Shorter stay in the hospital
• General minimization of the risk which comes along with a hip operation, in particular with an FES which might be fatal
• Makes a decision for a hip prosthesis easier

Apart from the feeling of the operator, this is done in a relatively uncontrolled manner, which may, in some, fortunately only rare cases, lead to the fracture of the thigh shaft. As far as driving in the forming rasps is concerned, or speaking more generally, as far as the modeling of the prosthesis bearing is concerned, an innovation seems to be long overdue ..."
