McCarthy Mini-Sternotomy Retractor with Universal Lift

The McCarthy Mini-Sternotomy Retractor with Universal Lift is a specialized, compact chest spreader system designed to provide surgical access through smaller sternotomy openings during cardiac procedures. Combining a modified 5-inch spreading frame with malleable wire basket retractors and a removable Universal Lift attachment, the system supports stable retraction and enhanced operative visualization during mini-sternotomy approaches.

Retractor Maker manufactures and supplies the McCarthy Mini-Sternotomy Retractor set for hospitals, cardiac surgical centers, medical equipment distributors, and OEM partners globally. By utilizing compact spreading bars and specialized lifting components, the assembly helps surgical teams maintain clear surgical exposure through limited sternal incisions.

What is the McCarthy Mini-Sternotomy Retractor?

The McCarthy Mini-Sternotomy Retractor is described as a 5-inch modified chest spreader system engineered specifically to operate within smaller sternal openings. Although small in footprint, the device is built strong to deliver reliable spreading force, featuring specialized blades intended to assist with tissue and bone retraction during either proximal or distal mini-sternotomy procedures.

The system incorporates malleable wire basket retractors in large and small configurations. These wire basket retractors allow precise tissue retraction while preserving the surgeon’s line of sight into the chest cavity. Additionally, an optional CO₂ tubing clip can be attached at any point along the rear bar of the retractor assembly when gas insufflation tubing management is required by the surgical team.

Universal Lift Mechanism

A core component of the system is the removable Universal Lift attachment. Designed to provide additional exposure during cardiac operations, the Universal Lift is placed on the sternal retractor arm attached to the patient’s left side.

During operation, the Universal Lift functions to raise the left side of the sternum. The lift mechanism acts like a jack to elevate the patient’s left chest approximately 1 to 2 inches. This mechanical elevation results in greater surgical exposure into the cardiac field, particularly when visualizing deeper valvular structures. Because the Universal Lift is completely removable, the surgical team can employ or detach the lifting assembly based on the specific exposure requirements of the procedure.

Uses and Applications

The McCarthy Mini-Sternotomy Retractor with Universal Lift is designed for a variety of minimally invasive cardiac surgical applications. The system’s compact spreading frame and specialized lifting accessories make it suitable for:

• Valve operations (including aortic and mitral valve repairs or replacements)

• Maze procedures for atrial fibrillation

• Other intracardiac surgical procedures requiring direct exposure

• Proximal or distal mini-sternotomy procedures

• Selected coronary artery bypass operations performed through a mini-sternotomy

As established in the product documentation, suitability for specific surgical procedures depends on the surgical approach, the planned operation, and the patient’s size.

Components

The McCarthy Mini-Sternotomy Retractor set is supplied with the following specialized spreading bars, mounting clamps, and malleable wire retractors:

Quantity	Component	Primary Role
1	Chest Spreader Dual Bars	Primary 5-inch modified spreading frame for sternal separation
1	Split Universal Clamp	Specialized mounting clamp for securing frame attachments
1	Universal Clamp	Multi-purpose clamping block for component integration
1	Main Bracket	Primary mounting bracket for supporting auxiliary retractor arms
1	Tube Holder	Secures surgical tubing within the operative field layout
1	Right Angle Transverse Bar	Structural crossbar for positioning auxiliary retractor elements
1	Large Wire Basket Retractor (Malleable)	Broad malleable wire basket for gentle tissue displacement
2	Small Wire Basket Retractor (Malleable)	Compact malleable wire baskets for targeted tissue retraction

Component Role Overview

• Chest Spreader Dual Bars: Serves as the main structural body of the retractor, providing modified 5-inch spreading action within mini-sternotomy incisions.

• Universal Clamps & Main Bracket: The Universal Clamp, Split Universal Clamp, and Main Bracket form the modular anchoring framework, allowing auxiliary bars and lifting attachments to connect securely to the spreading frame.

• Right Angle Transverse Bar & Tube Holder: The transverse bar extends over the spreading frame to position retraction components, while the tube holder provides a dedicated point for securing surgical tubing.

• Malleable Wire Basket Retractors: The set includes one large and two small wire basket retractors. Their malleable structure allows operating personnel to shape the wire contours to fit patient anatomy, gently holding surrounding tissues away from the primary field.

General Setup and Assembly

The components of the McCarthy Mini-Sternotomy Retractor set work together to establish a stable, elevated operative field:

1. Mount the Chest Spreader: Position the 5-inch modified chest spreader dual bars within the mini-sternotomy incision (proximal or distal) and advance the spreading mechanism to achieve initial sternal separation.

2. Attach Mounting Brackets: Secure the Main Bracket and Universal Clamps onto the spreader frame bars at the required working positions.

3. Install Transverse Bar and Accessories: Connect the Right Angle Transverse Bar to the bracket assembly and position the Tube Holder as needed for surgical tubing management.

4. Position Malleable Wire Basket Retractors: Insert the large or small malleable wire basket retractors into their mounting blocks, shaping the wire heads to displace soft tissues gently.

5. Attach the Universal Lift (When Indicated): Place the Universal Lift on the sternal retractor arm attached to the patient’s left side. Engage the lift mechanism to raise the left chest approximately 1 to 2 inches for expanded valvular exposure.

6. Perform System Check: Confirm that all clamps, brackets, and wire basket holders are firmly tightened before proceeding with intracardiac intervention.

Note: Assembly and use of the retractor should be performed by trained healthcare professionals according to applicable manufacturer instructions, hospital protocols, and the requirements of the surgical procedure.

Design Background

The McCarthy Mini-Sternotomy Retractor was designed by Patrick McCarthy, MD, Chief of Cardiac Services at Northwestern Memorial Hospital, in conjunction with Kapp Surgical Instrument, Inc.

The self-retaining system was created around the functional demands of minimally invasive cardiac surgery, specifically targeting the spatial challenges of exposing cardiac valves and internal structures through smaller sternal incisions. By modifying a standard chest spreader into a compact 5-inch frame and integrating malleable wire baskets with a left-sternal lifting mechanism, the design addresses both spreading and vertical elevation requirements in mini-sternotomy procedures.
