Surgery Assisting Technology Enabled Procedural Solutions
Healthcare organizations are challenged to frequently adapt to changing innovation, technology and service to optimize the patient journey and enhance health outcomes and efficiencies. Our Walter-Enabled Procedural Solutions compliment your current procedures – constantly evolving to help improve patient care, reduce costs, and enhance both outcomes and satisfaction.
We appreciate the unique approach a surgeon takes with every patient – every procedure. The WalterLorenz Surgical Assist Arm is thoughtfully designed to allow a multitude of instruments to be used depending on what the surgeon requires. Procedural solutions were designed in collaboration with a leading group of surgeons from multiple surgical specialties, whose unique insight and expertise was critical in helping ensure Walter’s value across a wide range of surgical disciplines and procedures.
To date, Walter has already provided value across surgical specialties including, Spine, CMF, Cardiothoracic, Plastics, Joint Reconstruction, and more. The list is rapidly expanding as new surgeons and specialties are exposed to Walter. Listed below are a few examples of Walter-Enabled Procedural Solutions.
The WalterLorenz Surgical Assist Arm impacts surgical retraction and instrument positioning in cardiothoracic procedures. Procedures include those such as Minimally Invasive Mitral Valve and Minimally Invasive Atrial Valve.
- The Walter Arm has simple, single-handed instrument positioning – allowing the surgeon to seamlessly work around the thoracic area.
- It allows maximum access and visualization for Minimally Invasive Mitral Value procedures and other procedures alike.
- The device improves operating room efficiency and surgeons are able to reposition instrumentation easily to gain continuous exposure of the mitral.
- It has the ability to connect to various atrial rake and lift instrumentation.
The Walter Arm can transform the operating room through its impact on surgical retraction and instrument positioning in rib fracture procedures. Procedures include those such as Posterolateral Thoracotomy (Rib Fracture), Scapular Retraction and Site Exposure Via Thoracotomy.
- The Walter Arm allows for maximum access and visualization for site access.
- It has the potential to improve operating room efficiency by the use of a steady holding force for scapula retraction.
- The device has simple, single-handed instrument positioning allowing for surgeons to access the fracture site
- Connects to instruments such as scapula retractors and Richardson retractors
The WalterLorenz Surgical Assist Arm impacts surgical retraction and instrument positioning in craniomaxillofacial (CMF) procedures – reducing fatigue and optimizing site exposure. The Walter Arm acts as a surgeons third arm, complimenting the surgical team’s ability to improve efficiency and productivity in various craniomaxillofacial procedures. Procedures include those such as Mandible Reconstruction with Fibula Free Flap.
- The Walter Arm provided maximum access and visualization of the entire surgical site.
- It direct connect to Army Navy provides steady retraction and easy one-handed positioning of the arm(s).
