The Bookler® IMA System is designed to allow gentle, controlled lifting of the chest wall while harvesting the Internal Mammary Artery. The IMA Ratcheting Mechanism features a micro twist ratchet that permits controlled lifting in increments less than 1mm. Each Blade is lifted independently for maximum control. It is easy to set up, simple to use and economical.
Position the Field Post at the patient's axilla, opposite the surgeon who will dissect the IMA. Load the Horizontal Bar into the Coupler and onto the Field Post. The distal end of the Horizontal Bar should have the jaws pointing up and should be positioned about 8 - 10" (20 - 25cm)above the patient. The Jaws should be over the midway point between the sternum and the nipple.
Insert the Cross Bar (with scalloped edge facing towards the field post) into the Jaws of the Horizontal bar and tighten. Insert the Blades into the Ratchet Mechanism. Open the retaining clips on the ends of the Cross Bar and slide the Ratchet Mechanism onto the Cross Bar. Relock the retaining clip and repeat on the opposite end. The hooks of the retractor blade are placed under the sternum. Lift by turning the thumbscrews of the Ratchet Mechanism.
