The Meniscus Suturing Device is designed to apply quick, strong, reliable suture repair for transplanted or torn menisci. The new suturing device utilizes the chain stitch, a common, single-thread sewing stitch. The device is simple to use, has internal fault protection and safety mechanisms, and comes apart easily. The Meniscus Suturing Device operates on basic pneumatic and mechanical concepts. A pneumatic system powers the needle and grabber system and ties into the existing nitrogen supply already present in operating rooms. Mechanical systems maintain the appropriate tension in the suturing system. Both the receptor arm and needle assembly are disposable. A simple two-button system makes the device easy for any orthopedic surgeon to operate. The major benefits the suturing device provides include a tremendous reduction in operating time and decreased complexity of meniscus repair.
