Description / Intended Use - Kapp Surgical Instrument The Rosenkranz Instrucciones De Uso

Excellent and consistent heart valve exposure of the right and left atrium, tricuspid,
and mitral valves in pediatric and small child cases is fundamental to intracardiac
TM
surgical and minimally invasive procedures. By using the Rosenkranz Pediatric
Open Heart Retractor, the surgeon can gain the optimum exposure necessary for a
successful surgical outcome.

DESCRIPTION / INTENDED USE

TM
The Rosenkranz Pediatric Open Heart Retractor is a unique retractor with adjustable self-
retaining atrial and ventricular retractor blades that provides maximum exposure of all heart
chambers during heart valve replacement or congenital heart defect surgery, while enhancing
visualization of the intracardiac anatomy. This product is available in the following sizes:
Pediatric (age 0-1 year) and Small Child (age 1-5 years). Recommendations for cleaning and
sterilization are included in this manual.
The device is supplied non-sterile and must be cleaned and sterilized before use.
PRE-SURGICAL ASSEMBLY
Figure #1 Position chest spreader as shown.
Figure #2 Slide the retractor Main Bracket (A) onto the chest spreader mounting bar, with the
two locking screws (F, Fig 6) away from the chest cavity.
Figure #3 Mount the Side Arm Attachment (B) onto the end of the Main Bracket by sliding its
mounting base down onto the locking screw (G, Fig 6). Then slide one Universal Clamp (H, Fig
6) onto the Side Arm Attachment. Mount 2 additional Universal Clamps onto the Main Bracket
cross bar (C) by removing the locking nut (D) and sliding the universal clamps onto the bar.
Replace the locking nut and tighten it into its original secured position.
Either the top or bottom hole on the Universal Clamp can be used to mount it onto the cross bar.
The other mounting hole in the Universal Clamp is then used to mount the retractor blade.
Figure #4 The way that the chest spreader is positioned on the patient is ultimately the decision
of the surgeon. However, it is recommended that the chest spreader ratchet be positioned toward
the patient's head and the chest spreader blades placed into the patient's chest. Then, from the
perspective of the surgeon: First, the center retractor blade should be placed. Second, the
retractor blade toward the patient's head or left of center (cephalad) should be placed. Third, the
retractor blade toward the patient's feet should be placed, allowing for complete exposure.
TM
Figure #5 This is the fully assembled Rosenkranz Pediatric Retractor. A malleable copper
blade (E) for bendable adjustments is supplied with a rectangular clamp for attachment to the
ratchet rack bar, as a fourth retraction point.

Note: To achieve optimum exposure, the retractor blades and Universal Clamps can be easily
repositioned during surgery by loosening the wing nut on the top of the Universal Clamp(s) and
then retightening it in the new position.
