Abstract

The present invention is formed of a dressing material having a hemostatic effect and is realized in a flower shape. Provided is a hemostatic member for the cervix, which comprises a petal portion having a relatively low dressing density, wherein the hemostatic member and the hemostatic member are housed therein and the hemostatic member is located at the hemostatic site. The technical gist is a hemostatic member kit for the cervix, which is composed of an applicator for providing the above.

Description

The present invention relates to a hemostatic member for the cervix, and more particularly to a device for effectively stopping bleeding at the hemostatic site by being inserted into the affected area during a histological examination of the cervix or an operation of the cervix.

When a trauma occurs on the body, blood coagulation is performed by the blood coagulation mechanism even with simple measures if the wound is not deep. However, if the wound is deep or if the tissue is cut off for surgery or examination, there is a great need to perform artificial hemostasis on the affected area to prevent excessive bleeding.

As a prior art related to the present invention, there is known "Chitosan-based hemostatic dressing material and method for producing the same" of Korean Registered Patent No. 10-1700107, which was filed and registered by the present applicant.

The conventional chitosan-based hemostatic dressing is composed of 100% chitosan substance, has a predetermined size and shape, and is applied to a wound or surgical site of a human body to be involved in hemostasis and recovery of the wound or surgical site. It is characterized by including a dressing material and an auxiliary member that is bonded to at least one surface of the chitosan dressing material to prevent desorption of fibers and maintain the shape of the chitosan dressing material.

The main uses of such chitosan are limited to wastewater treatment fields such as flocculants, heavy metal adsorbents and dye wastewater purifiers, and agricultural fields such as soil conditioners, insecticides, plant antiviral agents and pesticides. While elucidating the advantages and various characteristics of chitosan, its scope has been further expanded to include food and beverage applications, health and hygiene applications, cosmetic applications, textile-related applications, and pharmaceutical applications.

In this way, we try to provide a hemostatic dressing that can be used universally due to the useful function of chitosan. Conventional techniques can be usefully used as a dressing for hemostasis on the outer skin of the body that appears on the outside, but a general-purpose dressing for surgery or treatment of body organs having a special structure and shape inside the body. Then there is a limit to hemostasis.

The present invention seeks to provide effective hemostasis for affected areas that occur during surgery or diagnostic histology for cervical cancer in females. For this purpose, there is a need for a hemostatic member capable of achieving an effective hemostatic action on the affected area, rather than a gauze-like form that can be used for general purposes as in the prior art.

Due to such a need, the applicant has decided to form a hemostatic chitosan non-woven material into a round-shaped hemostatic mass as a hemostatic member to be inserted into the affected area during examination or surgery of uterine tissue. We have applied for a hemostatic member of the chitosan base for the cervix (Korean patent application No. 10-2017-0127526).

The prior art is a hemostatic member having a round shape, and it is necessary to improve the shape for hemostasis management after tissue collection.

As shown in FIG. 1, the hemostatic member 100 according to the present invention is formed of a dressing material having a hemostatic action, is realized in a flower shape, is composed of a plurality of petal portions 120, and has a plurality of petal portions 120 when applied to the affected portion. The petal portion 120 is characterized in that it is selectively formed so as to narrow or expand in a bud shape.

The present invention is not a conventional round-shaped hemostatic member, but a hemostatic member 110 provided in a flower shape when inserted into an affected area, which is formed of a dressing material having a hemostatic action, and a plurality of petal portions 120 are formed on the affected area. It is realized that it expands or narrows freely according to the shape of the disease, and has the advantages that the contact with the affected area is close, the contact area is wide, and hemostasis management is easy.

In particular, the round-shaped hemostatic member does not come into close contact with the side of a spherical affected area such as the cervix, so that hemostasis management to the cervix is insufficient.

When the flower-shaped hemostatic member according to the present invention is inserted into the affected area with or without a speculum, a part of the petal portion 120 can be naturally expanded, and the petal portion can be expanded. A part of 120 is realized in a narrowed form (that is, forming a flower core part) according to the shape of the affected part, and a part is realized in an expanded form (that is, forming a petal part).

That is, in the hemostatic member according to the present invention, only a part of the petal portion 120 expands according to the shape of the affected portion, or the entire petal portion 120 expands according to the shape of the affected portion, such as the cervix. It ensures rapid hemostasis management while being very close to the shape of the affected area.

As described above, the hemostatic member 100 for the cervix according to the present invention is formed of a dressing material having a hemostatic action, is realized in a flower shape, and has a flower core portion 110 formed in the central portion and the flower core portion 110. It is formed by a plurality of petal portions 120 formed in the peripheral portion.

Here, the flower core portion 110 can mean a region in which the petal portion 120 does not spread according to the shape of the affected portion when applied to the affected portion, and in addition, a peripheral portion of the flower core portion 110, that is, a petal. The region where the portion 120 extends can be distinguished from the petal portion 120 corresponding to the flower core portion 110.

As one embodiment of the present invention, the petal portion 120 is characterized by having a relatively lower dressing density than the flower core portion 110.

The present invention is not a conventional round-shaped hemostatic member, but a hemostatic member 100 provided in a flower shape when inserted into an affected area, which is formed of a dressing material having a hemostatic effect, but is relatively a dressing material. It is composed of a flower core 110 having a high density, that is, a central part in which the dressing is densely formed, and a petal 120 having a relatively low density of the dressing as compared with the flower core 110. It was done.

Here, the diameter of the flower core portion 110 is preferably 15 to 25 mm, and the diameter of the hemostatic member 100 forming the petal portion 120 is preferably 30 to 60 mm, that is, in the overall hemostatic member 100, the dressing material is used. The diameter of the portion having a relatively high density is 15 to 25 mm, preferably 20 mm, and the diameter of the portion having a relatively low density of the dressing is about 30 to 60 mm, preferably about 40 mm. This is large enough to cover the cervix when inserted into the cervix, and the flower core 110, which has a relatively high density of dressing material, provides more hemostatic action.

Further, the flower core portion 110 is formed to have a constant height, or the height is realized to be relatively higher than that of the petal portion 120, and the density of the dressing material having a hemostatic effect is the flower core portion. It can be formed to be higher at 110 so that more hemostatic action is performed.

In particular, as shown in FIG. 2, the cervical part 110 is excised in a conical shape so as to be in close contact with the hemostasis site by conization to remove the irregular shape or cancer tissue observed with the naked eye. Allows rapid hemostasis of large amounts of blood in contact with. That is, the flower core 110 is suitable for hemostasis management after cervical cancer surgery (conical resection).

Here, as described above, when the flower core portion 110 and the petal portion 120 are applied to the affected portion, the portion where the petal portion 120 is narrowed to the central portion naturally corresponding to the shape of the affected portion becomes the flower core portion 110. The portion where the petal portion 120 extends around the flower core portion 110 can be the petal portion 120 corresponding to the flower core portion 110. While the petals 120 are all expanded according to the shape of the affected area, the flower core 110 may be morphologically indistinguishable. In this case, the surface area is maximized, which is advantageous for hemostasis management for a specific affected area. It can also be applied to.

Further, as described above, the flower core portion 110 and the petal portion 120 can be classified by different shapes and heights of the flower core portion 110 and the petal portion 120, the density of the dressing material, and the like. When the height of the core portion 110 is higher than that of the petal portion 120 and the dressing material is formed to have a higher density and applied to an affected area such as the cervix, at the time of conization and tissue collection. It was applied to be more advantageous for each hemostasis management.

As described above, the present invention provides a flower-shaped hemostatic member, and by realizing the petal portion 120, the hemostatic member according to the present invention can secure a large surface area, and thus a tissue for cervical cancer examination. It is possible to tightly adhere to the bent atypical affected area that occurs after biopsy and conization, and is very suitable for hemostasis management of the affected area related to the cervix.

That is, the conventional spherical cervical hemostatic member is not easy to stop cervical cervical edge (side) side after sampling, whereas the hemostatic member according to the present invention has its morphological characteristics (wide surface area). ) Has the characteristic that both the center of the cervix (conization) and the edge of the cervix (at the time of sample) are easy to manage hemostasis.

Here, if the density of the petals 120 (the number of petals) is insufficient, there may be vacant portions, and it may not be easy to stop bleeding at the edge of the cervix. If the density of the flower core portion 110 is insufficient, hemostasis may not be easy because the dressing material does not adhere to the portion cut by the conization, so that the density of the petal portion 120 and the flower core portion 110 is high. It is adjusted and formed so that hemostasis management is easy.

Further, when the hemostatic member 100 according to the present invention is provided in a state where the petal portion is expanded, it can be inserted into the affected portion by using a speculum, and is provided in a bud-shaped narrowed state. In some cases, it is inserted into the affected area and formed to expand into a flower shape when hemostasis occurs. When provided in the shape of a bud, it is formed to facilitate insertion into the affected area, facilitate storage, and after insertion into the affected area, expand into a flower shape to be advantageous for hemostasis management.

Further, the hemostatic member 100 may further contain an X-ray (X-ray) sensitive substance inside. This can be utilized for grasping the position of the hemostatic member 100 inserted inside the body.

As described above, the present invention is a flower-shaped hemostatic member 100 formed of a dressing material having a hemostatic action, and is realized in a form advantageous for hemostasis management after tissue collection and hemostatic management after conical resection, and the uterus. Provided is a hemostatic member 100 having excellent hemostatic performance for cervical indications. In particular, it is formed in a flower shape to provide an aesthetic feeling to the user of the cervical hemostatic member 100.

Further, a thread 130 is formed at the lower end of the flower core portion 110, and the thread 130 further contains an X-ray (X-ray) sensitive substance, so that the hemostatic member is inserted into the body. It can be utilized for grasping the position of the 100, and when the hemostasis member 100 is removed after sufficient hemostasis is performed, the end of the thread 130 can be pulled to easily remove the hemostasis member 100.

On the other hand, the dressing material having a hemostatic effect forming the hemostatic member 100 according to the present invention can be made of only a fiber-based non-woven fabric, and if necessary, is provided by weaving with a non-woven fabric containing a functional component. Alternatively, it is also possible to form and provide a coating layer made of substances having various functional components on the nonwoven fabric.

The dressing material may be chitosan, cellulose (cotton, silk or hemp), regenerated cellulose (rayon or human silk), alginate and casein, or cellulose (cotton, silk or hemp), regenerated cellulose (rayon or hemp). Rayon), alginate and casein are mixed with chitosan and provided in the form of a non-woven fabric to realize a flower shape.

That is, the dressing material may be composed of only a fiber-based nonwoven fabric, or may be composed of only a chitosan-based nonwoven fabric in order to utilize the useful functions of chitosan. In this case, when only chitosan is applied, gelation may progress and the material may become brittle, making it difficult to maintain strength and shape. Cellulose (cotton, silk or linen) and regenerated cellulose (rayon or human silk) may be added to chitosan. ), Alginate and casein can be mixed and produced.

In particular, when rayon is mixed with chitosan to produce a dressing material, the rayon does not dissolve even if it is treated with an acid, and it can be provided as a suitable embodiment because it plays a role of increasing the absorption rate.

Further, the dressing material is provided in the form of a non-woven fabric in which a hemostatic material is mixed, or is provided in the form of a non-woven fabric in which a coating layer made of a hemostatic material is formed on a single layer or a plurality of layers on the surface.

The hemostatic material has a better ability to absorb blood, has an action of coating the affected area, has excellent biocompatibility, is not toxic, and has excellent biodegradability. Carboxymethyl chitosan (CMCS), carboxy Methyl cellulose (Carboxymethylcellulose, CMC), Chitosan Succinate, Sodium Alginate, Hyaluronic Acid, Collagen, Chondroitin sulfate, Chondroitin sulfate, Chondroitin sulfate, Chondroitin sulfate, Chondroitin sulfate, Chondroitin sulfate, Chondroitin sulfate, Chondroitin sulfate. poly-γ-glutamic acid, pullulan, kaolin, zeolite, chondroitin sulfate, calcium chloride, calcium chloride, calcium chloride , Catecol, and polyurethane foam, any one or a combination of two or more can be used.

On the other hand, as shown in FIG. 3, the hemostatic member 100 is formed long in the length direction, and one side is a rolling member 140 having a cutting portion 141 cut by the number of petals of the petal portion 120 in one direction. It can be realized by winding it around.

That is, the length of the rolling member 140 is determined in consideration of the diameter of the hemostatic member 100, and the cutting portions 141 are formed by the number of petal portions 120, but the height of the cutting portions 141 gradually increases in the winding direction. It is formed to be higher and wider, and the petals 120 in the outer shell have a relatively larger petal size, and the distance between the petals 120 is further widened.

As shown in FIG. 3A, the rolling member 140 is formed longer in the length direction in consideration of the diameter of the hemostatic member 100, and is an upper portion except for a portion corresponding to the height of the flower core portion 110. A cutting portion 141 corresponding to the number of petals of the petal portion 120 and the shape, size (width) and length of the petals is formed in the petal portion 120. At this time, a cutting portion 141 that is longer and wider is realized as it goes in the winding direction, and the petals of the petal portion 120 become larger and wider as it goes from the flower core portion 110 to the outer shell. , To have a shape that is more advantageous for hemostasis management after tissue collection.

Further, as shown in FIG. 3B, in order to further increase the size (diameter) of the hemostatic member 100, a plurality of the rolling members 140 are stacked as necessary to increase the thickness of the hemostatic member 100. At this time, the size of the hemostatic member 100 and the density of the dressing material can be adjusted so that the plurality of rolling members 140 are overlapped with each other by placing a step in the winding direction.

Further, the flower core portion 110 can be realized in a shape in which the horizontal cross-sectional area becomes narrower as the lower portion goes downward. This can be realized by a method in which the lower ends of the rolling members 140 are overlapped with a step when a plurality of the rolling members 140 are stacked, or the lower ends can be formed at different heights.

This is due to the morphological property that the lower portion of the flower core portion 110 becomes narrower toward the lower side, so that friction due to internal compression of the vagina can be minimized when the cervix is removed after hemostasis management. Therefore, the removal of the hemostatic member is facilitated.

As another embodiment of the present invention, a hemostatic member kit for the cervix is provided, which is formed of a dressing material having a hemostatic effect, is realized in a flower shape, and is composed of a plurality of petals 120 to the affected area. At the time of application, a plurality of the petal portions 120 are formed so as to selectively narrow or expand in a bud shape, and a hemostatic member 100 having a thread 130 formed at the lower end portion of the flower core portion 120 and the hemostatic member 100 are formed. It is characterized in that it is composed of an applicator 200 that houses the member 100 inside and provides the hemostatic member to the hemostatic site.

The hemostatic member 100 according to another embodiment of the present invention is the same as the flower-shaped hemostatic member 100 as described above or shown in FIGS. 1 to 3, and the applicator 200 is such. It plays a role of accommodating the hemostatic member 100 inside and providing the hemostatic member 100 to the hemostatic site.

The applicator 200 is elongated in the length direction to favor cervical indications and has an overall curved or cylindrical shape to minimize irritation when inserted into the cervix. It is formed in a shape, and the front end is also formed in a hemispherical shape to enable smooth insertion into the affected area.

That is, the applicator 200 is inserted into the cervix with the hemostatic member 100 housed inside the applicator 200, and the hemostatic member 100 is pushed out so that the hemostatic member 100 is provided to the hemostatic site. The applicator 200 serves to assist the hemostatic member 100 to be easily and accurately provided to the hemostatic site.

The applicator 200 is made of a polyolefin-based material (LDPE, LLDPE, HDPE). This satisfies the physical properties for the hemostatic member 100 to be smoothly provided to the outside of the applicator 200, and prevents the applicator 200 from damaging surrounding tissues when inserted into the body. , A material that is biologically stable.

As shown in FIGS. 4 to 8, the applicator 200 has a body 210 in which a space portion 211 in which the hemostatic member 100 is accommodated is formed at a front end portion, and the hemostatic member which is accommodated inside the body 210.

That is, the hemostatic member 100 according to the present invention is housed in the space 211 of the body 210, and at this time, the hemostatic member 100 is narrowed in a bud shape. After that, when the hemostatic member 100 is pushed out of the body 210 by using the handle 220 housed inside the body 210, the petal portion 120 of the hemostatic member 100 gradually expands while coming out of the body 210. However, it is expanded into a flower shape to provide a flower-shaped hemostatic member 100.

Further, the body 210 has a cross-sectional area relatively narrower than that of the space portion 211 formed so as to accommodate the hemostatic member 100, and is long enough to communicate with the space portion 211. It includes a handle accommodating portion 212 formed long in the radial direction.

Here, the front end portion of the space portion 211 is formed in a curved surface shape, and when the hemostatic member 100 is provided to the outside of the body 210, the opening / closing portion is elastically released by the pushing force of the hemostatic member 100. It is characterized in that 211a is formed.

The opening / closing portion 211a is formed to be narrowed when the applicator 200 is inserted into the body, and the front end portion of the space portion 211 of the body 210 has a curved surface shape to facilitate insertion into the body. It is formed so as not to irritate surrounding tissues. After the insertion into the affected portion, the opening / closing portion 211a is opened while being cracked by the force of pushing the hemostatic member 100 while pulling out to the outside, and the petal portion 120 is expanded to realize the flower-shaped hemostatic member 100.
