Skin wound stitching instrument

Abstract

The present invention discloses a skin wound stapler, which is characterized in that the both sides of a skin wound (1) are provided with strip-shaped base cloth (2), the base cloth is connected with a plurality of locking devices, each locking device is composed of a support strip (4), latches (5) and a tension belt (3), the upper surface of the support strip is provided with latches (5) at intervals, the lower surface of the support strip is connected with the base cloth, the latches consist of upper latches (9) and lower latches (8), the upper surfaces of the lower latches and the lower surfaces of the upper latches are respectively provided with convex slots and concave slots which are matched mutually, the tension belt penetrates the latches at the both sides of the wound, and the tension belt is regulated and fixed by the locking function of the upper latches and the lower latches, so as to provide the proper suturing force to the wound, further to constitute the skin stapler. The invention is used for suturing the linear or curved wounds, which can effectively shorten the surgical suture time, facilitate the nursing of the post-operative wounds, provide the smooth degree of the wound healing and reduce the scar residues.

Description

technical field [0001] The invention relates to a skin wound suturing device, which belongs to the field of medical appliances. Background technique [0002] Skin wounds, especially post-surgical wounds, are mainly linear wounds, and such wounds are usually closed with medical sutures. This kind of operation requires a long time for suturing, which will inevitably increase the risk of the patient's operation. At the same time, after the wound heals, it usually leaves a significant "centipede"-like scar, and the patient needs to go to the hospital again to remove the stitches. Another suture method commonly used in clinic is to use a device similar to a stapler to staple the skin on both sides of the wound together. This method is more convenient to use than sutures and saves operation time, but it is harmful to the healing quality of the wound, especially However, there is no significant difference between the residual scar and traditional sutures, and the patient still nee...

AI Technical Summary

Problems solved by technology

However, in order to ensure that the wound is closed tightly and the wound is not excessively squeezed, the medical device has strict requirements on the operation of the surgeon; while the zipper is closed, it is impossible to adjust the wound skin edge that is not yet flush in time under direct vision; At the same time, the closed zipper is not conducive to the ventilation of the wound, nursing and timely discharge of wound excrement; there is also a potential risk of twisting the surrounding tissue into the zipper when the wound is closed with a zipper

Chinese patents 022454810 and 2005200074389 are also based on similar design ideas, and some partial improvements have been made to the skin zipper, but there is still no substantial change to the existing problems

However, the locking device of this appliance can only be locked in one direction and cannot be loosened. "The adjustment of the suturing force of the wound can only be increased but not decreased", which will cause the following problems:

[0006] 2. Doctors need to be extra careful during clinical application. Once tightened too much, the appliance can only be scrapped. If it is used reluctantly, it will seriously affect the healing quality of the wound

If the closing force is too large, it will affect the smoothness of the skin edge of the wound and cause the scar to increase after healing; if the closing force is too large, it will compress the skin edge of the wound and affect the blood supply of the wound; Tension blisters occur due to excessive force on the pasting surface

[0007] 3. The patented spines have a serrated structure, and the adjustment of the wound suture force can only be increased step by step. This may cause the suture force to be slightly insufficient when the previous sawtooth is fixed, and the spines are further tightened to fix the next sawtooth. When the suturing force is slightly larger, it is impossible to continuously fine-tune the wound suturing force to meet the clinical demand for the best suturing force

[0008] 4. In order to meet the set function of the patented strip support belt and spines, they can only be made of relatively rigid metal or polymer materials, which makes this patent unable to meet the closure needs of arc-shaped wounds well

Forcibly applied to arc-shaped wounds will lead to significant inconsistencies in the force of different parts of the arc-shaped wound, thereby affecting the healing quality of the wound, resulting in a decrease in the flatness of the wound and an increase in residual scars
