Description

Skin wound net closed subsides

Technical Field

The utility model relates to a skin wound closed nursing medical technical field, more specifically says, it relates to a skin wound net closed subsides.

Background

Closure of skin wounds, such as surgical incisions and accidental tears or wounds, is critical to reduce the risk of infection, promote optimal healing of the incision or wound, and require rapid wound closure and careful skin edge approximation. Closing a skin wound requires a special device to pull the two sides of the skin wound together to promote healing of the skin wound and reduce the formation of scar tissue.

The needle and thread suture is the most traditional method for closing skin wounds, is widely applied, has the advantages of no limitation of the shape and the size of the wounds, low price and multiple defects. The needle and thread sewing has high technical requirements on operators, and the sewing process is time-consuming and labor-consuming; for patients, after the sutured wound is healed, scars of the centipede feet are obvious; the patient needs to be partially anesthetized in the suturing process, and the secondary pain is brought to the patient in the suture removing process after the wound is healed; poor sutures can prolong wound healing time. The needle and thread sewing method cannot meet the requirement of rapid development of modern medicine to a certain extent, and particularly cannot be applied to situations such as field operation, temporary first aid, battlefield rescue and the like.

The stitching and sewing are the development and innovation of needle and thread sewing, the wound closing speed is high, but the stitching and the needle and thread sewing have the common obvious defect, foreign matters are left in the wound, the metal stitching nail needs to be removed after the wound is healed, and meanwhile, the obvious scars are brought to the skin of a patient.

Both needle and thread suturing and staple suturing belong to invasive skin wound closing modes, and recently, several different types of non-invasive skin wound closing modes such as glue closing, lock catch closing and the like are developed. These emerging skin wound closure modalities have many advantages and also suffer from various degrees of drawbacks. The glue closed wound patient has strong foreign body sensation and poor follow-up nursing effect, and the closed skin wound has a large risk of cracking because the glue can not resist the tension of tissues on two sides frequently.

The buckle closure comprises two modes of zipper closure and zipper closure, and the action principles of the two modes are basically the same. The principle is that flexible positioning devices are adhered to two sides of a skin wound, and then the skin is oppositely pulled to gather towards the middle of the wound through a specific adjustable and locking mechanism fixed on the flexible positioning devices, so that the purpose of closing the skin wound is achieved. Various patent documents published internationally, such as US zipper CLOSURE type patent entitled "SLIDE FASTENER injection SKIN lock CLOSURE APPARATUS AND Techniques" (publication No. US 3516409A), german zipper CLOSURE type patent entitled "TEMPORAERER NDVERSCHLUSS" (publication No. DE3444782A 1), US zipper CLOSURE type patent entitled "Surgical fastening device for the expansion of Tissue" (publication No. US 5571138A), AND japanese patent entitled "RGICAL INCISION AND CLOSURE APPARATUS (publication No: JP 2021090813A), the invention name of the zipper closed patent applied in china by kanecar design limited, canada, the invention name of the zipper closed patent applied in china by krause limited, is" system for moving AND stretching plastic Tissue "(publication No. CN 1293848C), the invention name of the zipper closed patent applied in china by krause limited, is" interlaced composition AND method for manufacturing the same "(publication No. CN 1889903A), the chinese zipper closed patent, the invention name of the instrument for Closing wound" (publication No. CN 1013731B), the US zipper closed patent, the invention name of the device for secure close Tissue open with Minimized scaring "(US 01760B 2), the invention name of the SKIN opening Closing device" (publication No. CN 2064366U), the invention name of the SKIN suture wound instrument (publication No. CN 1012271B), AND the invention name of the instrument for Closing wound "(publication No. CN 34629322Y, etc.).

The closed special closed utensil of zip fastener closure and zip fastener appearance has alleviateed postoperative medical personnel greatly and has accomplished the closed work load of skin wound, and the patient need not to endure the pain of skin secondary wound, and skin wound closure process need not local anesthesia, and the organism is invaded to the no foreign object in the closed utensil operation process, is favorable to the nursing, and the later stage need not to take out stitches and tear the nail open and handle, and the scar obviously alleviates behind the skin wound healing.

The special device for closing the zipper and the pull buckle is complex in structure and high in manufacturing cost, generally comprises two adhesive blocks with back adhesive, which are arranged in a separated and symmetrical mode and have a certain area, a locking structure and the like, wherein the locking structure is fixed on the adhesive blocks and is made of high polymer materials. After the medical care personnel use the special appliance to complete the skin wound closure, the adhesive blocks on the two sides of the special appliance are adhered to the surface of the skin around the wound for a long time, so that skin anaphylactic reaction is easily caused, and the skin is uncomfortable, itchy, red and swollen and the like. The existing skin wound closing devices can only carry out unidirectional adjustment to generate resultant force for closing the skin wound, the requirements that the closing force applied to the wound needs to be increased or reduced in the wound closing process and the wound healing process of a patient cannot be met by medical workers, and only new devices can be replaced after misoperation, so that resource waste and increase of medical cost are caused. Some skin wound closing devices can adjust the resultant force for closing the skin wound in two directions, but the structure is complex and the effect is not obvious. The regulation locking device made of the polymer raw materials is a locking structure block with a certain area and height, and is located above the skin wound, the protruding structure increases the risk that the wound is invaded by foreign matters, and the larger shielding area is not beneficial to the nursing of the wound.

In summary, how to provide a skin wound closing device which is more beneficial to closing a skin wound and is convenient for nursing is a problem to be urgently solved by those skilled in the art at present.
