Areas of use and limitations of use

2.1.1

Intended use

► Connect the rasp to the THA handle, see usage instructions TA015090. ► Prepare the medullary cavity implant site with CoreHip® rasps of ascending sizes.

Note The CoreHip® rasps have different geometric and color markings for the height of the prosthesis shoulder and the femoral osteotomy. The different lines 1/2 of the CoreHip® hip endoprosthesis system are consistently identified by different color markings 3: ■ Varus line a: green ■ Standard line b: yellow ■ Valgus line c: blue ■ Dysplasia line: red (not included in example figure) ► Drive in rasp only up to the marking 1/2 of the planned variant, see CoreHip® OP-Manual. ► Before inserting the implants, carry out a test reduction and examine joint mobility, joint stability and leg length.

Validated reprocessing procedure

3.1

General safety instructions

Note Adhere to national statutory regulations, national and international standards and directives, and local, clinical hygiene instructions for sterile processing. Note For patients with Creutzfeldt-Jakob disease (CJD), suspected CJD or possible variants of CJD, observe the relevant national regulations concerning the reprocessing of products. Note Mechanical reprocessing should be favored over manual cleaning as it gives better and more reliable results. Note Successful processing of this medical device can only be ensured if the processing method is first validated. The operator/sterile processing technician is responsible for this. Note If there is no final sterilization, then a virucidal disinfectant must be used.

The CoreHip® rasps are used during implanting of a CoreHip® hip prosthesis for preparation of the implant site and for test repositioning of the joint.

Note For up-to-date information about reprocessing and material compatibility, see B. Braun eIFU at eifu.bbraun.com The validated steam sterilization procedure was carried out in the Aesculap sterile container system.

Safety information

2.2.1

Clinical user

General safety information To prevent damage caused by improper setup or operation, and to not compromise the manufacturer warranty and liability: ► Use the product only according to these instructions for use. ► Follow the safety and maintenance instructions. ► Ensure that the product and its accessories are operated and used only by persons with the requisite training, knowledge and experience. ► Store any new or unused products in a dry, clean, and safe place. ► Prior to use, check that the product is in good working order. ► Keep the instructions for use accessible for the user. Note The user is obligated to report all severe events in connection with the product to the manufacturer and the responsible authorities of the state in which the user is located. Notes on surgical procedures It is the user's responsibility to ensure that the surgical procedure is performed correctly. Appropriate clinical training as well as a theoretical and practical proficiency of all the required operating techniques, including the use of this product, are prerequisites for the successful use of this product. The user is required to obtain information from the manufacturer if there is an unclear preoperative situation regarding the use of the product.

2.2.2

Sterility

The product is delivered in an unsterile condition. ► Clean the new product after removing its transport packaging and prior to its initial sterilization.

2.3

Application

WARNING Risk of injury and/or malfunction! ► Prior to each use, inspect the product for loose, bent, broken, cracked, worn, or fractured components. ► Always carry out a function test prior to each use of the product. WARNING Bone fractures in the implant bed will affect the anchoring of the implants! ► Avoid bone fractures through careful operative techniques. WARNING Risk to patient if the implant inlays are damaged! In the case of certain combinations of hip rasps and (trial) implant inlays, the inlays can come into contact with the rasp teeth. This can cause plastic/metal abrasion and the inlay can be damaged. ► In the case of the following combinations, ensure that the inlay does not contact the rasp teeth.

General information

Dried or affixed surgical residues can make cleaning more difficult or ineffective and lead to corrosion. Therefore the time interval between application and processing should not exceed 6 h; also, neither fixating pre-cleaning temperatures >45 °C nor fixating disinfecting agents (active ingredient: aldehydes/alcohols) should be used. Excessive measures of neutralizing agents or basic cleaners may result in a chemical attack and/or to fading and the laser marking becoming unreadable visually or by machine for stainless steel. Residues containing chlorine or chlorides e.g. in surgical residues, medicines, saline solutions and in the service water used for cleaning, disinfection and sterilization will cause corrosion damage (pitting, stress corrosion) and result in the destruction of stainless steel products. These must be removed by rinsing thoroughly with demineralized water and then drying. Additional drying, if necessary. Only process chemicals that have been tested and approved (e.g. VAH or FDA approval or CE mark) and which are compatible with the product’s materials according to the chemical manufacturers’ recommendations may be used for processing the product. All the chemical manufacturer's application specifications must be strictly observed. Failure to do so can result in the following problems: ■ Optical changes of materials, e.g. fading or discoloration of titanium or aluminum. For aluminum, the application/process solution only needs to be of pH >8 to cause visible surface changes. ■ Material damage such as corrosion, cracks, fracturing, premature aging or swelling. ► Do not use metal cleaning brushes or other abrasives that would damage the product surfaces and could cause corrosion. ► Further detailed advice on hygienically safe and material-/value-preserving reprocessing can be found at www.ak-i.org, link to "AKI-Brochures", "Red brochure".

3.3

Reusable products

Influences of the reprocessing which lead to damage to the product are not known. A careful visual and functional inspection before the next use is the best opportunity to recognize a product that is no longer functional, see Inspection.

3.4

Preparations at the place of use

► If applicable, rinse non-visible surfaces preferably with deionized water, with a disposable syringe for example. ► Remove any visible surgical residues to the extent possible with a damp, lint-free cloth. ► Transport the dry product in a sealed waste container for cleaning and disinfection within 6 hours.

3.5

Cleaning/Disinfection

3.5.1

Product-specific safety information on the reprocessing method

Damage to or destruction of the product due to inappropriate cleaning/disinfecting agents and/or excessive temperatures! ► Following the manufacturer's instructions, use cleaning and disinfecting agents – that are approved for example, on aluminum, plastic materials, and high-grade steel, – that do not attack softeners (e.g., in silicone). ► Observe specifications regarding concentration, temperature and exposure time. ► Do not exceed the maximum allowable disinfection temperature of 95 °C. For products with plasma layers (e.g. Noir instruments), the layer is attacked or removed when special cleaning procedures with the addition of oxidizing chemicals (e.g. hydrogen peroxide H2O2) are used. ► Do not use oxidizing chemicals for cleaning. ► Use suitable cleaning/disinfecting agents if the product is disposed of in a wet condition. To prevent foaming and

degradation of the efficacy of the process chemicals: prior to mechanical cleaning and disinfection, rinse the product thoroughly with running water. ► If bone or tissue residue is present, the instrument must be pre-cleaned manually (using a brush).

3.5.2

► Check visible surfaces for residues after mechanical cleaning/disinfecting.
