Adjustable skin wound stapler

Abstract

The invention discloses an adjustable skin wound stapler. The adjustable skin wound stapler includes main stapler bodies and patch stapler bodies which are connected mutually; the main stapler bodies and the patch stapler bodies are arranged alternatively; the main stapler bodies and the patch stapler bodies consist of two side base clothes and thorn strip locking devices; each thorn strip lock fastener device includes a support strip, a lock fastener and a thorn strip; the lower surfaces of the support strips are connected to the base clothes; the lock fasteners are arranged the base clothes at one sides of the main stapler bodies and the patch stapler bodies; and one ends of the thorn strips are arranged on the base clothes at the other sides of the main stapler bodies and the patch stapler bodies, and the other ends of the thorn strips are movably connected to the lock fasteners. The adjustable skin wound stapler is breathable, is adjustable in tightness, is wide in application range, and is excellent in suture.

Description

technical field [0001] The invention relates to a stapler for medical supplies, in particular to an adjustable skin wound stapler. Background technique [0002] Skin wounds, especially wounds after surgical operations, are wounds of various shapes, and such wounds are generally 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 ...

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, the timely discharge of nursing care and wound excrement; when the wound is closed with a zipper, there is a potential risk of twisting the surrounding tissue into the zipper

The "skin wound locker" disclosed in Patent Publication No. CN1234327 can only suture irregular wounds, but cannot suture straight and arc wounds.

[0004] Chinese Patent Publication No. CN101112326 discloses "a skin wound stapler", that is, an adjustable "skin wound stapler". The adjustable device needs to be adjusted with a tool similar to a flat screwdriver. Operating room appliances are not practical

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] 1. In the case of temporary wound closure in clinical application, when the wound needs to be opened again, the patent design cannot meet the requirements. The patent CN1524507 sacrifices the advantages of the aforementioned patent CN87108125 in this respect;

[0007] 2. Doctors need to be extra careful in 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, resulting in increased scars 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; if the closing force is too large, the skin may stick tension blister

[0008] 3. The patented spines and the support strips of the locks are rigid link structures, and the suturing distance of each spine to the wound must be equal, which may occur when the suture distance of the previous spine is long and the next spine is slightly short. In some cases, the suture of the previous spine is not tight, and the continuous fine-tuning of the wound suture force cannot be realized to meet the clinical demand for the best suture force

[0009] 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
