Blair Acetabular Cup Positioner

The Blair Acetabular Cup Positioner is a specialized orthopedic instrument designed to assist with the controlled positioning and manipulation of an acetabular cup during hip arthroplasty procedures.

Its extended 11.5" (29.2 cm) overall length provides reach to the acetabular working area, while the 1" (2.54 cm) shaft offset provides an offset working configuration for positioning the instrument around the operative site.

The working head has defined internal and external diameters, providing a specified interface for engaging and positioning the compatible acetabular cup.

Key Features

• Designed for acetabular cup positioning
• 11.5" (29.2 cm) overall length
• 1" (2.54 cm) shaft offset
• 1.18" (3 cm) internal head diameter
• 1.5" (3.8 cm) external head diameter
• Extended shaft for access to the acetabular region
• Offset design for controlled positioning
• Suitable for hip arthroplasty applications

Design and Configuration

The Blair Acetabular Cup Positioner combines an elongated shaft with an offset working configuration and a defined head designed to engage the acetabular cup.

The 1" (2.54 cm) shaft offset positions the working head away from the primary shaft axis. This offset can provide an alternative approach and help with instrument positioning within the acetabular operative field.

Acetabular Cup Engagement

The working head has two specified diameter measurements:

• Inside Diameter: 1.18" (3 cm)
• Outside Diameter: 1.5" (3.8 cm)

These dimensions define the internal and external profile of the head and should be considered when determining compatibility with the intended acetabular cup system.

Shaft Offset

The 1" (2.54 cm) shaft offset is a key feature of the instrument. The offset changes the position of the working head relative to the shaft, allowing the instrument to approach the acetabular cup from an offset orientation.

This can be useful when positioning the cup within the acetabulum while maintaining access and control of the instrument.

Extended Working Length

The 11.5" (29.2 cm) overall length provides an extended reach to the acetabular working area. The length allows the working head to be positioned at the surgical site while the handle remains accessible to the user.

The combination of extended length and offset shaft provides a specialized configuration for hip arthroplasty applications.

Surgical Applications

The Blair Acetabular Cup Positioner is intended to assist with:

• Acetabular cup positioning
• Controlled manipulation of an acetabular cup
• Hip arthroplasty procedures
• Alignment and positioning of compatible acetabular components
• Procedures requiring an offset cup-positioning instrument

The instrument should be used according to the surgical technique and compatible implant system requirements.

Head Dimensions

The internal and external head dimensions provide the specified working profile of the cup-positioning interface.

Technical Specifications

Handling and Use Considerations

Select and use the positioner according to the compatible acetabular cup system and surgical technique. Ensure the working head is properly positioned with the cup before applying controlled manipulation.

Before use, inspect the shaft, offset section, working head, and overall instrument for visible damage or defects. Follow the healthcare facility's established procedures for cleaning, inspection, sterilization, maintenance, and storage.
