Abstract

The application relates to a surgical sponge comprising a plurality of layers of gauze and sutures. The multi-layered gauze has one or more open sides. The suture is adapted to secure or close the open side. The suture is made from one or more lines of contrasting material.

Description

Surgical sponge

The application is a divisional application of patent application with the application number of 201510728621.6, the application date of 2015, 10 months and 30 days and the application name of surgical sponge.

Technical Field

The application relates to a surgical sponge. More particularly, the present application relates to a surgical sponge having a contrasting suture.

Background

Gauze sponges are commonly used in surgery to absorb blood and interstitial fluid and to deactivate anatomical tissue and protect vital structures during surgery. Gauze sponges for medical use typically comprise cotton and/or nonwoven materials and fabrics and are provided in a variety of sizes, multiple layers. These sponges are generally soft, difficult to hair and contain radio-opaque stripes or lines so that they can be detected and located by X-rays if accidentally left in a wound or in the patient's body.

Different types of surgical sponges are available having different characteristics. The abdominal sponge is specifically designed for use in procedures requiring large incisions, such as laparotomy or thoracotomy. They are also commonly stained with physiological saline and used as a pad to protect the telescoping viscera. Conventionally, the abdominal sponge is made up of a combination of layers of woven gauze and/or nonwoven material stitched together by threads. The threads and gauze are traditionally of matching color, white. Thus, the suture will be visibly incorporated into the gauze fabric. Such sponges have at least the following drawbacks:

1) When used during surgery, the entire sponge becomes less visible, especially when it is immersed in red blood and body fluids; and

2) Any thread off is difficult to identify during quality control and during surgery.

It is an object of the present application to provide a sponge which overcomes or ameliorates the above-mentioned disadvantages, or at least to provide a useful alternative sponge.

Disclosure of Invention

According to the present application, there is provided a surgical sponge comprising:

multiple layers of gauze with one or more open sides; and

a suture for securing or closing the open side;

wherein the suture is formed from one or more lines of contrasting material.

Preferably, the thread is in sharp contrast in its appearance to the gauze. The appearance may include color and/or texture. The texture may include physical composition and structure.

In a preferred embodiment, the gauze is white. The one or more contrast-sharp lines are preferably selected from one or a combination of the following: fluorescent green yellow, fluorescent green or fluorescent yellow. Thus, contrast sharp lines can be easily seen against a white background without being too glaring or too glaring.

Preferably, the thread is made of one or more non-absorbent materials. In this way, the thread is not easily stained with blood or other liquid, so that its inherent appearance and visibility can be maintained when in use.

Preferably, the sponge may be five or six layers. The five-layer sponge may include a top layer and a bottom layer formed by folding one piece of cotton gauze in half, and a three-layer middle layer made of nonwoven viscose and/or polyester. The six layers of sponge may include 6 layers of cotton gauze.

Alternatively, the sponge may be formed in part from a piece of cotton gauze that is divided into three equal portions that are folded over one another.

In a preferred embodiment, each layer is preferably rectangular or square in shape. The layers of sponge are preferably stitched together by one or more threads to form a stitch along and around the open side. More preferably, the suture is further disposed diagonally across the surface of the sponge.

Detailed Description

It should be noted that the threads mentioned in this specification are in sharp contrast to gauze due to their general appearance. It should be appreciated that the appearance may include color and/or texture.

Referring to fig. 1-2, an abdominal sponge 10A is shown having multiple layers of gauze 12. The abdominal sponge 10A has three open sides 14,16 and 18, and a suture 20 adapted to secure or close each of the three open sides 14,16 and 18. The stitch 2 9 is made using a contrasting thread 22.

Although not evident in the black and white drawing, in this embodiment the gauze 12 is substantially white, while the contrasting, vivid color of the thread 22 is fluorescent greenish yellow. However, it should be noted that the color of the contrast sharp line 22 may be selected from one or a combination of the following: fluorescent green yellow, fluorescent green or fluorescent yellow. These three colors have a commonality, namely a weaker fluorescent color. These fluorescent colors have the following advantages:

1) So that the contrast sharp line 22 is readily visible and dark in color against the white gauze 12 background;

2) When the entire sponge 10 is wetted with blood, the inherent luminescent properties of the fluorescent color are highlighted, which is of great significance as it makes an otherwise invisible sponge immersed in red blood during surgery visible to the naked eye.

In addition to the above, in the present embodiment, the fluorescent greenish yellow color of the contrastingly contrasted line 22 is relatively soft but conspicuous against the white background of the gauze 22, and thus is easily visible during the daytime. This is beneficial in making the contrast sharp line 22 very noticeable, which is important in quality control processes where any dislocation or chip will be found and identified for removal. In addition, it will be appreciated that the soft, fluorescent, but less glaring or glaring, contrasting, sharp line 22 acts as a trademark that, in a somewhat fashionable feel, allows the manufacturer, supplier or seller of the sponge 10A to be immediately identified by the user.

It should be noted that, although not shown in the figures, the thread 22 is made of one or more non-absorbent materials having a texture different from gauze. These non-absorbent materials have different compositions and structures, resulting in a contrasting grain and appearance. The thread 22 is less prone to staining by blood or other liquids and therefore retains its inherent appearance and visibility when in use. This is advantageous, in particular, in surgical procedures where the sponge is usually soaked in red blood and is therefore easily confused with an organ. A non-absorbent thread with a contrasting appearance will reduce or eliminate the likelihood of any visual confusion.

Referring now to fig. 3, a five-layer sponge 10A is shown. The five-layer sponge 10A has top and bottom layers 26&28 formed by folding in half a continuous piece of cotton gauze 24A, and a three-layer middle layer 30 made of nonwoven viscose and/or polyester. The sponge 10A is capable of absorbing up to 12 times its own weight of liquid, and is thus suitable for use in bleeding or hemorrhagic wounds.

In another embodiment, the sponge 10B is shown with 6 layers. The six-layer sponge 10B is partially formed from one continuous sheet 24B, the sheet 24B being folded in half to form the top and bottom sheets 32&34. The sponge 10B also includes four intermediate layers 36, all of which are made of cotton threads. The sponge 10B is capable of absorbing up to 8 times its own weight of liquid.

As shown in fig. 5 and 6, the "facing gauze 24A or 24B" may be arranged such that it is divided into three equal parts folded over each other. In this way, the intermediate ply 30 or 36 may be placed between the stacks. It should be noted that the number of intermediate layers may vary, depending on the application of the different sponges.

Referring to fig. 1 and 2, the sponge 10A or 10B of the present application is substantially square in shape. Thus, the layer 30 may be substantially square in shape, for example. As shown in FIGS. 1 and 2, all of the layers of sponge 10A, for example, may be stitched together with a contrasting thread 22 to form a stitch 20 along and around the open sides 14,16&18 and diagonally across the sponge 10A. Such that diagonal stitches 20 form intersections on the surface of the sponge 10A. The position of suture 20 is best shown in fig. 7 and 8 by downwardly directed arrows 44& 46. It should be appreciated that in other embodiments, the sponge 10A or 10B may be rectangular. It should also be noted that the layer of sponge has no exposed flash or other flash that would be included in the cut edges to prevent fraying or scuffing.

As shown in fig. 1-8, the sponge 10A or 10B has X-ray detectable threads 48, which may be monofilament threads, multifilament yarns, continuous strips or similar inserts made of polyester threads and barium sulfate, for example, which must be X-ray opaque. This is beneficial in that the sponge 10A or 10B is made detectable by X-rays when the sponge 10A or 10B is accidentally left in the patient's body or in a wound.

Referring to fig. 9, three folded and rolled sponges 10A are used in the surgical procedure.

Having now described in detail preferred embodiments of the present application, it will be apparent to those skilled in the art that the surgical gauze of the present application may provide at least the following advantages:

1. the visibility of the sponge soaked in red in the cavity in the operation process is improved, so that the conspicuity is improved;

2. it serves as a trademark so that the manufacturer, supplier or seller of the sponge can be immediately approved by the user before, during and after its use; and

3. which makes it easy to find any breaks or fragments out of line during the quality control process, thus reducing the possibility of the user returning the product after opening the package and finding that it is defective.

It will be appreciated by persons skilled in the art that variations and modifications of the described application other than those specifically described above are readily possible. For example, when the color of the gauze is not white but a different color, the color of the contrasting thread may be varied to produce a contrasting effect. All such variations and modifications are within the scope and spirit of the application as determined by the foregoing description.
