Problems solved by technology

[0005] The main function of the above auxiliary tension reducing devices is to close the wound, and also have a small effect of reducing skin tension; in clinical use, when the skin zipper is closed, it is easy to cause poor drainage of the wound, and it is inconvenient to change dressings; and the skin wound locker The locking device cannot be released and locked, and it is close to the skin and straddles the wound, which will also cause poor drainage of the wound, inconvenient dressing changes, and it is difficult to use it on uneven parts, such as sunken wounds and scars higher than the skin surface; skin thinning Although the tensioner overcomes the shortcomings of poor drainage and inconvenient dressing changes, it cannot avoid the chronic cutting effect of the suture on the wound and the difficulty in removing the suture caused by the suture being trapped in the skin tissue, and it does not absorb the wound exudate and simplify the process of reducing the wound. Tension suture technique, giving appropriate pressure to the wound to reduce bleeding, etc.

Embodiment 1

[0028] As shown in the figure, an auxiliary tension-reducing device used in surgical suture is a rounded cuboid, including a tension-reducing layer 1, an adsorption layer 2, a suture hole 3 and an observation hole 4; On the top, the two layers are tightly combined; the suture hole 3 and the observation hole 4 both run through the tension-reducing layer 1 and the adsorption layer 2; the suture holes are two rows and symmetrical.

Embodiment 2

[0030] An auxiliary tension-reducing device used in surgical suture, the rest is the same as that of Embodiment 1, and the observation hole 4 is located in the middle of two rows of suture holes 3 .

[0031] The spacing between the left-right symmetrical sewing holes 3 is equal to the spacing of the adjacent sewing holes 3 in a row, and the spacing is 10mm.

[0032] The material of the tension-reducing layer 1 may be medical polyethylene; the material of the absorption layer 2 may be absorbent cotton wrapped in non-woven fabric; the two layers are bonded together.

[0033] The medical polyethylene can be selected from low-density polyethylene, the product of Sinopec Beijing Yanshan Petrochemical Company, and the trade mark is LD100AC.

[0034] The non-woven fabric is medical spunlace non-woven fabric.

[0035] Described cotton is medical absorbent cotton.

Embodiment 3

[0037]An auxiliary tension-reducing device used in surgical suture of the present invention, when used clinically, the needle is first inserted from one suture hole 3 during surgical suture, and the needle is then exited from the other paired suture hole 3 after suturing the skin, and the operations are performed sequentially After completion, press the apparatus of the present invention to the top of the wound, tie up all the sutures and trim the sutures to complete the suture. It can achieve the dual effects of reducing wound tension and absorbing exudation.

[0038] Clinical use implementation of the present invention:

[0039] Patient 1, patients with hypoalbuminemia type I surgical incision, the surgical incision is 10cm, the length of the auxiliary tension reducing device of the present invention is 12cm, and the width is 2cm; there are two rows of suturing holes, 10 in each row, The distance between adjacent suture holes is 10mm; there are 9 observation holes with a di...

Abstract

The invention belongs to the technical field of medical instruments and provides an auxiliary relaxation instrument used in surgical suturing. The auxiliary relaxation instrument is of a rounded cuboid and includes a relaxation layer (1), an adsorbed layer (2), stitching holes (3) and observing holes (4), wherein the relaxation layer (1) is arranged on the adsorbed layer (2), and the relaxation layer (1) and the adsorbed layer (2) are closely combined; the stitching holes (3) and the observing holes (4) penetrate through the relaxation layer (1) and the adsorbed layer (2); the stitching holes (3) are arranged in two rows and are symmetrical in a left-right mode. According to the auxiliary relaxation instrument, in the fully intradermal suturing process of a wound, the skin relaxation suture technology is simplified, and meanwhile moderate pressure is exerted on the wound to reduce bleeding. Therefore, it is guaranteed that the distances between stitches are equal in the manual interrupted suturing process, scar hypertrophy and suture cutting effects due to overlarge skin tension are prevented, and finally the skin relaxation instrument achieves the purposes of accelerating wound closure, bringing convenience to wound dressing change and wound observation and preventing the scar hypertrophy.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a medical device for reducing skin tension in the process of suturing surgical incisions. Background technique [0002] At present, the surgical incision is more than 10cm and irregular incision, the incision tension is relatively high, and there are factors that affect incision healing such as hypoalbuminemia and diabetes. Newborns, elderly patients, and high-risk patients who may have abdominal wall incision dehiscence will be treated in the hospital. After the incision is sutured, a large tension is formed, which is prone to misalignment, scar hyperplasia and even wound dehiscence. If the suture removal time is prolonged, it is impossible to avoid the chronic cutting effect of the suture on the wound and the difficulty of suture removal caused by the suture being trapped in the skin tissue. [0003] At present, there are two main ways to reduce wound tensi...
