Description

Mechanical and remote control fixture for closing wounds and system therewith

The present invention relates to a holder, and more particularly to a holder suitable for closing a wound, and to a system for closing a wound, and more particularly to a system for mechanically and remotely closing a wound.

In the prior art, a closed wound or a healing wound is closed by a suture suture, a closure or a healing device, etc., for example, a staple holder can usually be used to staple the tissue to bind the lace. Cross stitch stitching.

In recent years, it has been developed to use a fastener or a closure to be inserted into a subcutaneous tissue for fixation, and the wound is closed by sutures through a fastener provided on the holder or closure, such as U.S. Patent 7,455,681 and US 7,686,829 has disclosed techniques for suturing with sutures using a wound closure.

US Patent No. 7,455,681 discloses a wound closure system comprising: a plurality of fasteners mechanically joined to the endothelial tissue surrounding the wound; a line extending between the fixtures to engage the anchors; and a bias A compression member that provides the tensile force that the suture pulls all of the fasteners. According to the previous case, the fixer comprises a plurality of barbs for firmly piercing the skin, and the fixer is mechanically fixed to the dermis, for example, a conventional medical skin tissue is fixed to the dermal tissue with a staple. Or use sutures to mechanically connect the fixture to the skin tissue.

No. 7,686,829 discloses a wound closure system comprising: a holder mechanically bonded to endothelial tissue on one side of a linear wound; a holder stretching device mechanically coupled to the other side of the wound The upper endothelium; and a line extending between the holder and the stretching device to movably connect the holder to the stretching device. According to the previous case, the holder also includes a plurality of barbs for firmly piercing the skin. Similarly, the holder is mechanically fixed to the skin tissue, for example, mechanically connected by conventional medical staples or sutures. Fixator and skin tissue. Further, in the prior system, each of the holders is connected to the holder stretching device by a wire (refer to Figure 1 of the previous case).

Again, as shown in Figure 1, the prior art often uses sutures to gradually close the wound in a manner similar to the lace cross-tie. In Fig. 1, a holder (A2) for piercing the skin is nailed around the wound (A1), and the suture (A3) is passed through a pull ring on each holder in a lace-like manner, and then pulled by a pull. The thread device (not shown) pulls the suture (A3) to gradually close the wound (A1). The main structure of the above fixer (A2), as shown in FIG. 2, can be designed as a long and narrow plate body (A21), and downward hook members (A22a and A22b) are respectively formed on both sides of the end portion adjacent to the plate body (A21).
