  • Suture reinforement material for automatic suturing device
    Patent number: 8177797
    Abstract: The present invention relates to a tubular suture reinforcement material suitable for use in automatic suturing devices that are widely used in surgical operations, etc. More specifically, the present invention relates to a tubular suture reinforcement material with which a tubular shape is easily obtained to thereby increase its productivity, and removal of thread is easily achieved. The present invention provides a tubular suture reinforcement material for an automatic suturing device formed by stacking two sheet-like materials and sewing together both ends of the two sheet-like materials using two chain stitches (intralooping stitches) each thread end at each sewing end is suitably extended, and the thread end is passed through an anterior loop continuous to the thread end, thereby preventing the thread from unraveling.

  • SUTURE REINFORCEMENT MATERIAL FOR AUTOMATIC SUTURING DEVICE
    Publication number: 20070049953
    Abstract: The present invention relates to a tubular suture reinforcement material suitable for use in automatic suturing devices that are widely used in surgical operations, etc. More specifically, the present invention relates to a tubular suture reinforcement material with which a tubular shape is easily obtained to thereby increase its productivity, and removal of thread is easily achieved. The present invention aims to overcome drawbacks such that sheet-like materials joined by the conventional temporary adhesion easily separate from each other, and the tubular suture reinforcement material manufactured using a running stitch requires a lot of time and skill, and removal of the thread is difficult depending on the kind of sheet-like material, sewing pitch, etc.
