Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surgical covering used as a pair of upper and lower sheets.

[0002]

2. Description of the Related Art It is known to cover a patient's body with an operating cloth provided with a fenestration so as to expose a surgical site in open surgery such as laparotomy, thoracotomy, and cecum. . conventionally,
A covering having a fenestration at a position corresponding to a surgical site, such as a laparotomy covering or a cecal covering, has been manufactured for each surgical site. When the sterilized wrapping is spread over the patient in a folded state, if the fenestration is provided in advance so that the surgical site is just exposed, the patient can cover the patient with a single operation. This is because it is possible to save preparation time and manpower until surgery. For this reason, for example, a cecal covering could not be used as a chest opening covering.

[0003] On the other hand, with the advance of surgical techniques, surgical methods for removing the gallbladder and cecum using a laparoscope have been performed. Laparoscopic surgery is a technique that has attracted attention because it is only necessary to make a few small holes near the affected part, and since it is possible to perform an excision operation without laparotomy, there is little disadvantage to the patient. In such a procedure using a laparoscope, if a covering with a large fenestration is used, sterilization and disinfection must be performed on unnecessary parts, so it is necessary to reduce the fenestration of the covering. desired. However, the smaller the fenestration is, the more difficult it is to align the fenestration with the surgical site when covering the patient with the covering. In addition, for the manufacturer of the cloth, there is a problem that various kinds of cloths having different positions of the fenestrations must be manufactured, and the manufacturing efficiency is not improved.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a surgical covering having a structure which can be easily applied to various surgical sites and which can improve manufacturing efficiency.

[0005]

SUMMARY OF THE INVENTION The present invention, which has solved the above-mentioned problems, is a surgical covering used in combination with a lower covering and an upper covering, wherein the lower covering has a size of 150 to 250 cm. It has a width and a length of 180 to 350 cm, and a first fenestration having a width of 30 to 50 cm and a length of 40 to 60 cm is formed near the center thereof.
m and a length of 100 to 140 cm, a second fenestration having a smaller area than the first fenestration is formed near the center thereof, and a second fenestration is formed on the upper surface side of the upper covering. The gist is that a liquid-absorbing waterproof portion having a surface liquid-absorbing layer and a back-surface waterproof layer is formed around the window.

[0006] In the above-described covering cloth, since the large lower covering cloth has the large first fenestration, it is possible to cover the patient without performing positioning, and to form the small second fenestration. Since the upper covering cloth has an area that can be handled by one person, positioning to the surgical site can be easily performed by one person.
In addition, no matter where the surgical site is located, only the surgical site can be accurately exposed by simply shifting the position of the upper cover, so that a single set of surgical covers can be used for many surgical operations. It is possible to use.

A configuration in which an adhesive layer is formed on the lower surface side of the upper cover and around the second fenestration is a preferable embodiment of the present invention because it can be immediately attached to an affected part.

The second fenestration has a width of 5 to 30 cm and a width of 20 to 5 cm.
It is preferably a square having a length of 0 cm. Not only the periphery of the second window portion of the upper cover but also the upper cover itself may be formed of a laminate sheet having a front liquid absorbing layer and a back waterproof layer. In addition, it is preferable that the lower cover is made of a nonwoven fabric having at least one surface subjected to a water-repellent treatment. Furthermore, by adopting a configuration in which a pocket and / or a liquid collecting bag (pouch) is attached to the upper surface side of the upper cover, storage of forceps and the like during surgery, and bodily fluid and blood that overflow during surgery are performed. It is convenient for receiving liquid.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The surgical covering of the present invention is based on the premise that a lower covering and an upper covering are used in combination. The surgical covering of the present invention will be described with reference to the drawings. As shown in FIG. 1, the lower cover 10 has a rectangular shape, and a first fenestration 11 is formed near the center. On the other hand, FIG. 2 shows an example of a square as the upper cover 20. A second window 21 is formed in the center of the upper cover 20.

The width of the lower cover 10 is 150 to 250 cm,
The length is 180-350 cm. If it is smaller than this, the whole body of the patient cannot be completely covered. On the other hand, if the size is larger than the above range, it is difficult to spread it alone, and two or more people are required to cover the patient, which is not preferable. The upper covering cloth 20 has a width of 100 to
140 cm, length of 100 to 140 cm, and lower covering cloth 10
Smaller than When the upper cover cloth is in this range, it is larger than the first window portion 11 of the lower cover cloth 10, so that unnecessary exposed portions of the skin do not occur. Although the upper cover cloth 20 has a square shape in the illustrated example, it may be a rectangular shape.
For the sake of convenience of explanation, it is assumed that “width” is smaller than “length”.

The first window 11 of the lower cover 10 has a width 30
５０50 cm, length 40４０60 cm. Lower cover 10
Has a total length of 180 cm or more, so that if the surgical site is on the patient's torso, the lower covering 10 may be extended from the head of the patient to the operating table side, or the legs may be extended. Only by this, the surgical site of the patient can be easily exposed from the first fenestration portion 11. The first fenestration 11 may be formed at the center of the lower cover 10 or may be formed by displacing it near one of the short sides. FIG. 1 shows an example in which it is displaced upward in the drawing. As represented by thoracotomy, surgical operations are often performed on the torso rather than the lower limbs, and it is often more appropriate for the first fenestration 11 to be slightly closer to the head. It is.

FIG. 2 shows an example of the rectangular shape of the second fenestration 21 of the upper cover 20. Can be formed according to Since the area of the second fenestration 21 is the minimum area that can be sterilized and disinfected as a surgical site, if it is too large, the portion that must be sterilized and disinfected becomes unnecessarily large, which is not preferable. When the second fenestration 21 is rectangular, the width is preferably 5 to 30 cm and the length is 20 to 50 cm.
In recent years, the size of the fenestration is sufficient for most surgical operations because the surgical area has been reduced in recent years.

FIG. 3 shows a patient 30 about 170 cm tall.
FIG. 2 is a schematic view showing a case where the lower cover 10 (width 210 cm, length 290 cm) having the same shape as that of FIG. 1 and the upper cover 20 having the same shape as that of FIG. The first fenestration is 30 cm wide and 45 cm long, and the second fenestration is 6 cm wide and 30 c long.
m. The first window portion 11 of the lower cover 10 is formed near the head such that the center in the length direction is 130 cm from the upper side of the lower cover 10. FIG. 3 shows an example in which the lower cover 10 is hung so that the center of the lower cover 10 is near the navel of the patient 30. It can be seen that the portion from the breast contact to the lower abdomen is included in the first fenestration 10. Therefore, the lower cover 10
Just shift the hooking position of the patient up or down a little,
Regardless of where the surgical site is located on the torso, it can be inserted into the first fenestration 11. Further, the upper cover 20 may be hung on the patient such that the second fenestration 21 corresponds to a surgical site. The second fenestration 21 can also be made horizontally long, and the manner in which the second fenestration 21 is hooked can be appropriately changed according to the surgical site and the shape of the window of the second fenestration 21.

The lower cover 10 may be made of a material that has such a flexibility that the periphery thereof hangs down when hung on a patient, and that does not allow blood, body fluids, bacteria, etc. to come into contact with the patient's skin. In consideration of the fact that it is disposable, a nonwoven fabric whose surface is subjected to a water-repellent treatment is preferable. Nonwoven fabrics have better bacterial barrier properties than woven fabrics woven with the same basis weight, and do not allow blood or bodily fluids to pass through if they are water-repellent. The basis weight of the nonwoven fabric is preferably 30 g / m ² or more in order to maintain barrier-free properties. In addition, the lower cover 10 may be configured by a single nonwoven fabric or a configuration in which two or more nonwoven fabrics are stacked.

Examples of the fibers constituting the nonwoven fabric include polyolefins such as polyethylene and polypropylene; polyesters; synthetic fibers such as polyamides; regenerated fibers such as rayon and cupra; and natural fibers such as cotton, silk and pulp (cellulose). Used. A composite fiber such as a core-sheath type or side-by-side may be used.

The method for producing the nonwoven fabric is not particularly limited, and nonwoven fabrics obtained by various known methods such as spunbonding, spunlace, thermal bonding, needle punching, and wet method can be used. The water-repellent treatment can be performed by a method such as applying a known water-repellent agent after forming the fiber itself or a nonwoven fabric. Instead of the water-repellent treatment, a material obtained by laminating a hydrophobic plastic film on a nonwoven fabric may be used as the lower cover cloth 10.

The upper cover 20 may employ any of the above-described structures as the material of the lower cover 10. At this time,
As shown in FIG. 4A, the second window part 2 is located on the upper surface side of the upper cover 20 (the surface opposite to the contact surface with the lower cover 10).
A liquid-absorbing and waterproofing part 22 is provided in the peripheral part of 1. As shown in FIG. 4B, a cross-sectional view taken along line AA of FIG. 4B, the liquid-absorbing waterproof portion 22 includes a front liquid-absorbing layer 22a and a rear waterproof layer 22b. The liquid-absorbing and waterproofing section 22 has an effect of absorbing blood and body fluids, so that the operation proceeds smoothly.

The surface liquid-absorbing layer 22a only needs to have a liquid-absorbing property, and is preferably a non-woven fabric formed of hydrophilic fibers such as cellulose, cotton, rayon and the like, and water-absorbing synthetic fibers. Further, a nonwoven fabric formed of a hydrophobic fiber subjected to a hydrophilic treatment or a nonwoven fabric formed of a nonwoven fabric and subjected to a hydrophilic treatment may be used. Back waterproof layer 2
2b is a layer for preventing blood or body fluid absorbed by the liquid absorbing layer 22a from oozing out to the lower surface of the upper cover 20, and is preferably an inexpensive thermoplastic resin film such as polyethylene or polypropylene.

The front liquid absorbing layer 22a and the back waterproof layer 22b are
Both can be laminated by a known laminating means such as passing them through a heat roll, or an adhering means using an adhesive.
Note that another layer may be provided between the front surface liquid absorbing layer 22a and the back surface waterproof layer 22b. Not only the periphery of the second window portion 21 of the upper covering 20 but also the entire upper covering 20
It may be a laminate including 2a and the back waterproof layer 22b.

The upper cover 20 has a lower surface side (a contact surface with the lower cover 10) and a periphery of the second window 21,
An adhesive layer 23 is provided. The adhesive layer 23 allows the upper cover 20 to be adhered to the skin around the operation area of the patient, so that the upper cover 20 does not shift during the operation. The pressure-sensitive adhesive layer 23 may be configured to be provided on the entire periphery of the second window portion 21 as shown in FIG.
A configuration may be provided partially in the peripheral portion of the second window portion 21. The type of the adhesive is not particularly limited. The surface of the pressure-sensitive adhesive layer 23 is preferably protected with release paper or the like until the use of the covering cloth.

The upper cover 20 may be constructed without the pressure-sensitive adhesive layer 23. In this case, the lower periphery of the second fenestration 21 of the upper cover and the skin around the operation part are fixed with an adhesive tape or sheet, or the upper periphery of the second fenestration 21 and the operation part are connected. By sticking so as to cover with the size drape, it is possible to employ a means for fixing the upper covering cloth 20.

As shown in FIG. 5, one or more pockets or liquid collecting bags (pouches) 24 are preferably mounted on the upper surface of the upper cover 20 on the left and right sides of the second window portion 21 in advance. . It is convenient for storing surgical tools and electric cords. In addition, it is preferable to attach one or more liquid collection bags together with (or instead of) the pockets, since the overflowing body fluid, blood, and the like can be received. The pocket (or liquid collecting bag) 24 can be formed by using a part of the covering cloth. However, when the sharp instrument is stored in the pocket, the covering cloth is prevented from being broken, or the liquid collecting bag can be formed. In order to reliably prevent the liquid leakage, it is preferable to separately form a pocket (or a liquid collecting bag) 24 in advance and attach the pocket 24 to the upper cover 20. In addition, a male member of a mechanical hook-and-loop fastener or an adhesive may be attached to the pocket (or liquid collection bag) 24 so as to be detachable from the upper cover 20. Pocket (or collection bag) 24
Can be freely changed.

As shown in FIG. 5, an appropriate number of cord holders 25 may be attached to the upper surface side of the upper cover 20. In some cases, such as when using an abdominal endoscope, it is difficult to perform surgery if the power cords are scattered in the vicinity of the operative part of the patient. Can be prevented. As the coat holder 25, one having a form in which a cord is simply passed through a loop and holding it, a clip-shaped one, or the like can be used. Note that the arrangement positions and locations of the pockets 24 and the cord holders 25 are not limited to the example shown in FIG. 5 and can be changed as appropriate.

[0024]

The surgical covering of the present invention uses a lower covering of a fixed shape in combination with an upper covering of a smaller area. Since there is only one fenestration, it is possible to cover the patient without positioning, and the upper cloth having a small second fenestration is reduced to an area that can be handled by one person. Can be easily positioned alone. In addition, no matter where the surgical site is located, only the surgical site can be accurately exposed by simply shifting the position of the upper cover, so that a single set of surgical covers can be used for many surgical operations. It is possible to use.

Further, the lower lining can be made to be a uniform standard, and the upper lining can be made of a uniform standard or several standards in which the position and size of the second window portion are slightly changed. By doing so, most surgical linings can be manufactured, so that the number of manufacturing lines is small and mass production is easy and efficient. As a result, an inexpensive disposable surgical covering can be provided.
