Abstract: The proposed meniscus suturing machine provides quick, strong, reliable sutures to torn medial menisci. An electronically controlled pneumatic system powers the suturing process. The meniscus suturing machine utilizes the chain stitch, a common sewing stitch, and applies it to the repair of torn menisci using only a single thread. The designed device is simple to use, with an on/off switch and fire button. While the device is simple, it has internal fault protection devices such as an automatic emergency shutoff and suture recovery loop. The device also comes apart easily, with a disposable needle-thread system. An autoclave sterilizes the remaining portion of the device. The initial application of the design is to suture medial menisci, but modifications will allow the suturing device to accommodate other areas too, such as the lateral meniscus. The benefits of the suturing device include a reduction in operating time and complexity of meniscus repairs.
