Bhargava Modular Offset Cup Liner Impactor

The Bhargava Modular Offset Cup Liner Impactor is a specialized orthopedic instrument designed to assist with acetabular cup liner impaction during minimally invasive total hip replacement procedures.

The instrument features a modular offset design with a working end that accepts individually interchangeable heads. These heads are sold separately and are designed to fit securely onto the impactor end.

The offset configuration provides an alternative approach compared with a straight impactor and is designed to help reduce the potential for edge loading and improper seating of the liner during the impaction process.

The instrument has an overall length of 15.85" (40.2 cm) and a 1" (2.54 cm) platform-end diameter.

Modular Head System

The Bhargava Modular Offset Cup Liner Impactor is designed to be used with individual interchangeable heads. The heads are sold separately and attach securely to the impactor end.

This modular arrangement allows the appropriate head to be selected according to the acetabular cup liner being impacted.

Important: The interchangeable impactor heads are not included with the impactor unless specifically supplied as a separate component or set.

Offset Design

The instrument incorporates an offset shaft configuration rather than a straight impactor profile.

The offset working geometry is designed to provide a more suitable approach to the acetabular cup liner during minimally invasive hip procedures. This configuration can help the user position the impactor appropriately while maintaining access to the operative site.

Acetabular Cup Liner Impaction

The primary purpose of the instrument is to assist with controlled impaction of an acetabular cup liner.

The design is intended to help avoid situations where a straight impactor may contribute to edge loading or improper liner seating. The offset configuration provides an alternative working angle for positioning the interchangeable head against the liner.

Surgical Applications

The Bhargava Modular Offset Cup Liner Impactor is designed for:

• Acetabular cup liner impaction
• Total hip replacement procedures
• Minimally invasive direct anterior approach THR
• MIS posterior approach THR
• Controlled positioning and seating of acetabular liners
• Procedures requiring an offset cup liner impactor

The appropriate interchangeable head should be selected according to the compatible liner and surgical system being used.

Interchangeable Heads

The impactor is designed to work with individual interchangeable heads that are sold separately. The selected head fits onto the impactor end and provides the appropriate interface for the acetabular cup liner.

This modular approach allows one impactor body to be used with different compatible head configurations rather than requiring a completely separate impactor for every liner size.

Working-End Characteristics

The impactor has a specified 1" (2.54 cm) platform-end diameter. The modular end is designed to accept the appropriate interchangeable head.

The head attachment area should be checked before use to ensure the selected head is correctly fitted and securely seated.

Extended Overall Length

The impactor measures 15.85" (40.2 cm) overall. Its extended length, combined with the offset shaft, provides reach to the acetabular working area during minimally invasive hip procedures.

The overall design allows the handle end to remain accessible while the interchangeable head is positioned at the operative site.

Design and Function

The instrument consists of an elongated offset shaft with a platform end for attachment of the selected interchangeable head.

The general operating sequence involves:

1. Select the appropriate compatible interchangeable head.
2. Securely attach the head to the impactor end.
3. Position the head against the acetabular cup liner.
4. Confirm appropriate alignment and seating before impaction.
5. Use the instrument according to the established surgical technique.

Technical Specifications

Handling and Use Considerations

Ensure that the selected interchangeable head is compatible with the intended acetabular cup liner and is securely attached before use.

The impactor and head should be inspected before use for visible damage, secure attachment, and proper condition. The interchangeable head should be correctly seated on the impactor before applying any impaction force.

Follow the healthcare facility's established procedures for cleaning, inspection, sterilization, maintenance, and storage.
