Smith+Nephew Introduces Adjustable FLOW FLEXTEND COBLATION Wand for Complex Hip Procedures

Smith+Nephew is deploying the FLOW FLEXTEND COBLATION Wand, an adjustable-angle radiofrequency device for orthopedic surgery. The instrument utilizes automated fluid management to perform soft tissue resection in hard-to-reach anatomies across various joint preservation procedures.

Articulating Tip Mechanics in Orthopedic Resection
Complex hip repairs frequently require navigation around dense capsular structures where standard elongated, fixed-angle instruments restrict maneuverability. The surgical wand incorporates a precision electrode with a flexible shaft mechanism engineered specifically for hip access. Operators configure the required angle prior to or during tissue engagement using a mechanical adjustment system. Once a desired angle is established, the mechanism locks into place, allowing the surgeon to release the control module without losing the selected geometry. This structural adaptability facilitates instrument insertion and removal by allowing the shaft to be temporarily straightened, increasing operational access to targeted tissues within confined joint spaces.

Automated Fluid Management and Radiofrequency Energy
The resection tool integrates proprietary FLOW~IQ technology, a system designed to regulate the application of radiofrequency energy in arthroscopic environments. The architecture automatically balances saline outflow with the applied radiofrequency energy. This automated fluid regulation mechanism ensures that the thermal and kinetic output corresponds with the clinical requirement for either high-speed tissue removal or precision sculpting, eliminating the need for manual fluid calibration during the resection cycle.

Anatomical Navigation and Capsular Preservation
The mechanical articulation and specific tip geometry are engineered to address structural challenges in joint preservation surgery. Dr. Joshua D. Harris, an orthopedic surgeon at Houston Methodist specializing in sports medicine, noted that the device's articulation provides versatility in the central compartment of the hip without requiring capsular disruption. Additionally, Dr. Jovan Laskovski of the Crystal Clinic Orthopaedic Center observed that the flexible tip geometry enables a precise capsule-to-labrum recess while preserving the surrounding capsular tissue. The implementation of this radiofrequency technology serves as an alternative to traditional mechanical debridement for soft tissue removal.

Radiofrequency ablation in arthroscopy relies on the generation of a localized plasma layer using a conductive fluid medium to break molecular bonds in soft tissue. This process operates at relatively low temperatures, typically between 40 and 70 degrees Celsius, compared to standard monopolar electrosurgery which relies on direct high-heat thermal destruction. The Smith+Nephew wand competes in the arthroscopic resection market against fixed-angle and articulating radiofrequency probes such as the Arthrex ApolloRF series and the Stryker Crossfire platform. While standard fixed-angle wands require the surgeon to alter the angle of approach by maneuvering the entire handpiece against the portal, articulating wands permit intra-articular angle modification. Furthermore, the integration of automated outflow management seeks to mitigate fluctuations in the plasma layer caused by variable saline flow, a parameter that is often managed manually or via independent fluid pump integrations in competing radiofrequency platforms.
