Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a mouth-binding type closing device.
Background
Wounds (also called as wound surfaces) which cannot be directly sutured usually need to be repaired by autologous tissue transplantation, namely a 'repair' mode, such as a skin flap or a flap. However, this approach can cause damage to the donor area and the difference in color and texture of the skin "supplemented" affects patient comfort and aesthetics.
In order to solve the above problems, the existing method is to use tissue expanders (tissue expanders) to repair the wound surface.
The expansion type tissue expander is the best tissue expander which is recognized in the world at present, has the strongest practicability and is most widely applied. However, after decades of use, it still has certain drawbacks:
(1) usually, hard base tissue is required for supporting, and when the support of the hard base tissue is lacked, the outward expansion efficiency of the expander is extremely low or even ineffective;
(2) usually, the stent is only implanted on one side of a wound surface, and the expansion effect is limited to the one side, so that the utilization efficiency and the expansion efficiency of tissues are limited;
(3) the expansion power of the classical filling type expander is derived from the expansion force generated by injected liquid, the expansion force is multidirectional, the stretching directions expected for the repair purpose are not completely consistent and even mutually perpendicular, so that the stretching efficiency of skin soft tissues is low, the acting force perpendicular to the skin is easy to cause skin thinning, ulceration, expander exposure, combined infection and the like, and the failure of the expansion operation can be caused in serious cases;
(4) the skin soft tissue obtained by expansion and presetting mostly needs to use a local skin flap transfer mode to reach a repair area.
In addition to tissue expanders, stretch bands are also a means of stretching normal skin around a wound bed. Although the stretching belt overcomes part of the defects of the expansion type dilator, the stretching belt can only utilize normal skin on two sides of the wound surface, and the efficiency is still limited. In addition, the crossing of the plurality of stretching belts is inconvenient for treating the wound surface below the stretching belts, and the normal skin on the two sides of the wound surface can leave the wound scars punctured when the stretching belts are placed.
Therefore, a repair device with improved wound repair efficiency, reduced complications and less trauma is needed.
