MICS Retractor (minimally invasive cardiac surgery)
KDI manufactures this surgical retractor for minimally invasive cardiac surgery procedures.
Each year more than 400,000 heart valve repair and valve replacement procedures are performed throughout the world. Today, specially trained cardiac surgeons are performing heart valve repairs and replacements using MICS, and these techniques allow access to the heart through smaller incisions using specialized, minimally invasive surgical retractor instruments and without separating the breastbone.
The MICS Retractor is a mechanical device that separates adjacent ribs, allowing surgeons to access the heart. MICS procedures typically allow for reduced blood loss during surgery, quicker patient recovery times and shorter hospital stays.
Surgical Retractor for MICS – KDI manufacturing operations:
- Laser marking
Surgical Retractor for MICS – Custom Life Test Equipment:
KDI designed and built custom test equipment for the MICS Retractor. Two images of the test equipment are featured at the top of the page. Both the CAD model and an image of the actual device are shown. Parts were fabricated with KDI’s in-house CNC machining capabilities.
Purpose of the Equipment: to test the Thoracotomy Retractor Rack and Blades (2) – cycling them at a given load for a given number of open and closing cycles. KDI built the equipment to meet the following customer specified requirements:
- Operates with 120 volts AC and 100 psi compressed air.
- Benchtop unit to be operated in an engineering lab
- Apply a constant load over the opening and closing range
- Count cycles completed
- Monitor the load applied and time to complete a cycle
- Must operate for tens of thousands of cycles
- The equipment must be easily programmable by the operator to be able to change the following variables:
- Speed of cycle, load applied, number of cycles and distance that the rack is opened and closed.
