A new internal mammary artery retractor

Area of Science:

• Thoracic Surgery
• Surgical Instrumentation
• Cardiothoracic Procedures

Background:

• Median sternotomy provides access to the thoracic cavity but can limit surgical exposure.
• Dissection of the internal mammary artery and resection of mediastinal tumors require optimal visualization.
• Existing retractors may not offer sufficient or adaptable exposure for complex thoracic procedures.

Purpose of the Study:

• To introduce a new retractor designed for asymmetric chest opening.
• To evaluate the safety and efficiency of this novel surgical instrument.

Main Methods:

• The study presents a new retractor incorporating a tilting mechanism for asymmetric thoracic cavity opening.
• The device modifies a standard retractor to lift one side of the chest while depressing the other post-median sternotomy.
• The retractor has been in routine clinical use since late 1987.

Main Results:

• The retractor facilitates asymmetric opening of the thoracic cavity.
• It has been utilized in over 3000 surgical operations as of April 1990.
• The instrument has demonstrated safety and efficiency in clinical practice.

Conclusions:

• The new asymmetric chest retractor is a safe and effective tool for thoracic surgery.
• Its applications include internal mammary artery dissection, mediastinal tumor resection, and pulmonary resections.
• The device enhances surgical exposure and maneuverability during median sternotomy.
