Description

Surgical wound protector {Wound protector}

The present invention relates to a surgical wound protector, and more particularly, to a surgical wound protector for preventing infection and damage during surgery by covering the inner incision of the skin incision site.

With the development of medical equipment and technology, the number of cases of laparoscopic surgery or robotic surgery replacing conventional open surgery is increasing. . Laparotomy is an operation performed while opening the chest or abdomen of the patient and visually checking the affected area. However, the open surgery method has a disadvantage that the incision site may be contaminated by bacteria, and in particular, in the case of cancer surgery, fine cancer cells separated from the tumor during the operation may settle in the incision site and metastasize the cancer. .

In order to solve this problem, a surgical pad is used, but this causes another problem in that the incision site must be incised larger than necessary to secure a space for inserting the pad. It goes without saying that the more incisions are made, the higher the probability of wound infection, the delayed recovery, and the greater the patient's pain. However, since the surgical pad is primarily intended for hemostasis, it does not completely cover the incision site when, for example, organ harvesting or tumor mass is removed.

Accordingly, Korean Utility Model Publication No. 20-0379005 (protective equipment for incision during surgery) has been proposed. The proposed protective equipment includes: a cover paper having a plurality of cut-out lines configured to be parallel at regular intervals; a protective pad which is integrally attached to the middle part of the cover paper in a direction perpendicular to the cut-out line and is applied with a material with good absorbency such as nonwoven fabric; an attachment part configured on one side of the cover paper based on the protective pad, attached and supported to the skin at the edge of the incision through an adhesive layer provided on the bottom surface, and configured to be divided into multiple sections through the cut-out line; It is configured on the other side of the cover paper based on the protective pad, and it is configured to be able to divide into multiple sections through the cut-out line, and is drawn into the incision surface to secure the surgical field and to isolate and block the surgical site and surrounding organs from each other. Wow; It is composed of a support positioned between each cut-out line in a state of being buried inside the cover paper.

Hereinafter, one embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

1 is a perspective view of a surgical wound protector 10 according to an embodiment of the present invention, and FIG. 2 is a view showing a state in which the cutting line 13c of the surgical wound protector shown in FIG. 1 is cut. In addition, FIG. 3 is a cross-sectional view taken along line A-A of FIG. 1 , and FIGS. 4A to 4D are views for explaining a method of using the surgical wound protector 10 .

Surgical wound protector 10 according to this embodiment, as shown in Figure 4b, is attached to the body of the open patient, the skin 100, the incision surface 103 of the incision hole 101 formed through the laparotomy. It has the purpose of covering and protecting. The incision hole 101 is a hole made by incision of the skin covering the affected part, and the incision surface 103 is the inner cut surface of the incision hole. The incision surface 103 is a place where a surgical knife has passed, and the risk of infection is high because the subcutaneous tissue is exposed.

As shown, the surgical wound protector 10 according to this embodiment includes a support sheet 13 , an adhesive layer 17 , and a release sheet 19 . The support sheet 13 is made of vinyl or polyethylene and has a flexible property. The support sheet 13 has a position fixing part 13a and a cut surface cover part 13b.

The position fixing part 13a is attached to the abdomen of the patient through the adhesive layer 17, and provides support so that the incision surface cover part 13b does not move forward, backward, left and right. The width or size of the position fixing part 13a may be changed as needed.

The cut surface cover portion 13b is formed in the center of the position fixing portion 13a to once cover the cut hole 101, and has a plurality of divided pieces 13e divided through the cutting line 13c. The cutting line 13c is a pre-formed dotted line-shaped sheath, and is ruptured when the user applies force to it. A plurality of divided pieces 13e are formed according to the rupture of the cutting line 13c. The divided piece 13e is folded in the direction of the arrow b in FIG. 4B by the user and attached to the subcutaneous tissue. The number of the divided pieces 13e may vary as needed.

An adhesive layer 17 is laminated on the bottom surface of the support sheet 13 for fixing the support sheet 13 . The pressure-sensitive adhesive layer 17 is a medical pressure-sensitive adhesive and is applied to the bottom surface of the position fixing portion 13a and the cut surface cover portion 13b to a predetermined thickness. The adhesive may be urethane-based. The adhesive layer 17 is covered with a release sheet 19 . The release sheet 19 is peeled off before using the wound protector 10 .

On the other hand, the guide ring 15 is integrally formed on the upper surface of the support sheet 13 . The guide ring 15 is a ring-shaped part that divides the position fixing part 13a and the incision surface cover part 13b. During surgery, the incision hole 101 is positioned to match the lower part of the incision surface cover part 13b. so as to guide the position of the support sheet 13 . The user, by positioning the incision hole 101 in the inner region of the guide ring 15, can easily and accurately fit the position of the support sheet 13 for the affected part.

This guide ring 15 takes the form of a closed curve, and as shown in FIG. 3 , has a space portion 15a therein. The space portion 15a can be opened downward through the rupture slit 15b and accommodates the sterilizing solution 15c. The rupture slit 15b is opened when lifting the positioning part 13a in the arrow c direction while pressing the guide ring 15 in the arrow f direction, as shown in FIG. 4d. As the rupture slit (15b) is opened, the internal sterilizing solution (15c) flows out and is applied between the position fixing part (13a) and the skin. The sterilizing solution 15c not only sterilizes bacteria that may remain on the skin, but also penetrates between the skin and the adhesive layer 17 so that the adhesive layer 17 is better separated.

The mounting method of the wound protector 10 having the above configuration is as follows. First, as shown in Figure 4a, the wound protector 10 is positioned on the upper portion of the incision hole 101, and then the release sheet 19 is peeled off in the direction of the arrow a and removed. As the release sheet 19 is removed, the adhesive layer 17 having adhesiveness is exposed.

Then, the wound protector 10 is adhesively fixed to the upper surface of the skin 100 . At this time, the incision hole 101 is positioned in the inner region of the guide ring 15 . When the fixation of the wound protector 10 is completed, the cutting line 13c is cut by pressing the cut surface cover part 13b downward. As the cutting line 13c is ruptured, the divided piece 13e is divided and struck downward. In this state, insert your finger and fold the segmented piece 13e in the direction of arrow b in FIG. 4B to attach it to the surface of the subcutaneous tissue.

As the above process is completed, as shown in FIG. 4C , the divided piece 13e covers the cut surface 103 . Since the incision surface 103 is blocked by the split piece 13e, even if the explants are withdrawn through the incision hole 101, the extract does not directly contact the incision surface 103, so it is safe.

When the use of the support sheet 13 is completed, the guide ring 15 is pressed in the direction of the arrow f, and at the same time, the position fixing part 13a is pulled up in the direction of the arrow c. As the position fixing part 13a is pulled up, the rupture slit 15b is opened, and the sterilizing solution 15c inside the space part 15a flows downward. The sterilizing liquid 15c that flows out sterilizes the surface of the skin and at the same time penetrates between the adhesive layer 17 and the skin, so that the adhesive layer 17 is more easily separated.

5 is a perspective view illustrating a modified example of the surgical wound protector 10 according to an embodiment of the present invention, and FIG. 6 is a cross-sectional view taken along line B-B of FIG. 5 . In addition, Figures 7a to 7c is a view for explaining a method of using the wound protector shown in Figure 5.

Hereinafter, the same reference numerals as the above reference numerals indicate the same members having the same functions, and repeated descriptions related thereto will be omitted.

Referring to the drawings, it can be seen that the surgical wound protector 10 is composed of a support sheet 13, an adhesive layer 17, a release sheet 19, a lower adhesive layer 21e, and a release tape 21f. .

The support sheet 13 is attached to the patient's skin 100 and is formed in the center of the position fixing portion 13a and the position fixing portion 13a to provide support and a cut surface inserted into the incision hole 101 . It includes a cover portion 21, a stopper projection 21b integral with the inner circumferential surface of the cut surface cover portion 21, and a guide ring 15 provided on the upper surface of the position fixing portion 13a. The support sheet 13 is molded and manufactured from a vinyl or polyethylene film and has a flexible property.

The cut surface cover part 21 takes the form of a barrel extending downward from the position fixing part 13a. The wound protector of FIG. 1 has a two-dimensional structure except for the guide ring, but the wound protector illustrated in FIG. 5 has a three-dimensional structure.

The cut surface cover part 21 covers and protects the cut surface 103 while being inserted into the secured cut hole 101, and a plurality of division sheaths 21c are formed at the lower end. The dividing sheath 21c is a cutting line extending upward from the bottom line of the cut surface cover part 21 . The reason for forming the dividing sheath 21c is to fold the lower end of the incision surface cover part 21 in the arrow k direction of FIG. 7B and attach it to the subcutaneous tissue.

A lower adhesive layer 21e is applied to the outer peripheral surface of the lower end of the cut-out cover 21, and a release tape 21f is attached to the outer surface of the lower adhesive layer 21e. The release tape 21f protects the lower adhesive layer 21e and is removed before use.

The stopper projection 21b serves to prevent the upward expansion of the dividing sheath 21c. The upward expansion means that the dividing sheath 21c is torn upward. If there is no stopper projection (21b), the division sheath (21c) is torn in the upward direction, it is impossible to properly cover the cut surface (103). The stopper protrusion 21b is integral with the cut surface cover part 21 and is thicker than the other parts. The stopper projection (21b) should be formed as low as possible and streamlined so as not to interfere with the extraction of the extract from the body.

The installation method of the wound protector 10 having the above configuration is as follows. First, after peeling off the release sheet 19 and the release tape 21f, the wound protector 10 is completely lowered in the arrow m direction of Figure 7a. According to the lowering of the wound protector 10 , the position fixing part 13a is adhesively fixed to the skin 100 , and the incision surface cover part 21 covers the incision surface 103 .

In this state, put your hand into the passage 21a of the incision cover part 21, and fold the lower end of the incision cover part 21 in the direction of the arrow k of FIG. 7b to adhere to the subcutaneous tissue.

In addition, in order to remove the wound protector 10, the part attached to the lower end of the cut surface cover part 21 is separated in the direction of the arrow m, and then the guide ring 15 is pressed in the direction of the arrow f and the position fixing part 13a ), pull up the edge in the direction of the arrow n. As described above, the sterilizing liquid inside the guide ring 15 flows out as the position fixing part 13a is pulled up, and the separation of the adhesive layer 17 from the skin is easily realized as described above.

8 is a cutaway perspective view showing another modified example of the surgical wound protector 10 according to an embodiment of the present invention.

As shown in FIG. 8 , the plastic deformation plate 23 is built in the cut surface cover part 21 . The plastic deformation plate 23 is a metal plate that is bent by an external force and maintains a bent state. When the incision surface cover part 21 having such a configuration is inserted into the incision hole 101 and bent in the same manner as in FIG. 7b , the incision surface cover part 21 is bent to come into contact with the subcutaneous tissue. Of course, even at this time, the lower adhesive layer (21e) serves to adhere the lower end of the cut surface cover portion 21 and the subcutaneous tissue. The wound protector 10 may maintain a more stably fixed state by the lower adhesive layer 21e and the plastic deformation plate 23 .

As mentioned above, although the present invention has been described in detail through specific embodiments, the present invention is not limited to the above embodiments, and various modifications are possible by those of ordinary skill within the scope of the technical spirit of the present invention.
