Surgical gauze assembly and surgical gauze supply device

Technical field

[0001] The present invention relates to an assembly of surgical gauze used during surgical operations and a surgical gauze supply device for supplying the surgical gauze to a surgeon.

Background technology

[0002] Surgical gauze has conventionally been folded one by one and then laminated to form an aggregate. From this laminated gauze aggregate, each surgical gauze is unfolded. Nurses and others were supplying the equipment to the surgeons. However, surgical gauze is frequently used in surgical operations for purposes such as grasping and wiping tissue or stopping bleeding, and dozens or hundreds of pieces of surgical gauze are used in a single operation. In this way, at a surgical site where a large number of surgical gauze are used, the work of picking up folded surgical gauze one by one, unfolding it and handing it to the surgeon is very difficult. This was a burdensome task for nurses and others. Here, in order to avoid the complication of the above-mentioned work and to make it easier to handle, the surgical gauze was packaged in a gauze holder equipped with a locking part that holds the surgical gauze in a removable manner. A surgical gauze package has been proposed (see Patent Document 1).

[0007] Preferably, each of the surgical gauzes has a rectangular shape, and the connecting thread extends from a vertex on a diagonal line of each of the surgical gauzes, and connects adjacent surgical gauzes. .

[0008] With this configuration, the surgical gauze can be taken out in a diagonally extending state. The ability to take out surgical gauze in such conditions is useful for performing detailed treatment procedures by holding one vertex of gauze and the diagonal vertex of the surgical gauze and stretching the surgical gauze. There are advantages when using.

[0009] In order to solve the above problems, a surgical gauze supply device according to the present invention includes a casing in which the above-mentioned surgical gauze assembly is housed, and a surgical gauze supply device formed in the casing, and in which each of the surgical gauze an extraction port for taking out the surgical gauze; a resistance applying part that provides resistance to the surgical gauze coming in and out from the extraction port; and a gauze stopper configured to restrict the withdrawal of the container.

[0010] With this configuration, the surgical gauze can be easily taken out one by one from the extraction port. In addition, since the resistance imparting part applies resistance to the insertion and removal of the surgical gauze, the surgical gauze can be taken out in a spread state, and the surgical gauze does not sink into the casing. Furthermore, since the surgical gauze assembly is housed within the casing, it is possible to prevent contamination from falling bacteria, etc., and to improve hygiene compared to when the surgical gauze assembly is exposed.

[0011] The gauze stopper allows the connecting thread to pass through while also allowing the surgical garter to pass through. a pair of stopper pieces arranged opposite each other so as to have a gap that can restrict the passage of the thread, and at least one end side of the pair of stopper pieces is open so that at least the connecting thread can be freely received in the gap. It can be configured as an edge.

[0012] Here, the gap between the pair of stopper pieces may be in the form of a slit, and at least a portion of the edge defining the gap of the stopper piece may be configured to be a cutting blade. Here, it is preferable that the open end of the stopper piece is tapered so that the connecting thread can be easily guided into the gap.

[0013] Furthermore, the gap between the pair of stopper pieces may be V-shaped, and at least a portion of the bottom edge of the V-shaped gap may be a cutting blade.

[0014] Further, the gauze stopper is connected to the casing by a hinge, and can be folded by rotating the gauze stopper about the hinge, and the shape of the casing in the folded state is It is preferable that the shape is in line with the . This allows downsizing.

[0020] Hereinafter, embodiments of a surgical gauze assembly and a surgical gauze supply device according to the present invention will be described with reference to the drawings. Figure 1 is a plan view of the surgical gauze assembly, Figure 2 is a perspective view of the surgical gauze supply device, Figure 3 is an enlarged view of the gauze stopper, and Figure 4 is an explanatory diagram of how to use the surgical gauze supply device.

[0021] As shown in FIG. 1, the surgical gauze assembly 10 is an assembly of a plurality of surgical gauze 1, each of which is connected in one direction by a connecting thread 2. Here, each surgical gauze 1 is square, and connecting threads 2 extend from diagonal vertices of each surgical gauze 1 to connect adjacent surgical gauze 1. In addition, the surgical gauze assembly 10 can be easily manufactured by sewing diagonally across each surgical gauze 1 with one connecting thread 2 to form the surgical gauze assembly 10. Further, the connecting thread 2 is connected to each surgical gauze 1 so as to be cut by pulling it with a predetermined force. Here, the size, material, etc. of each surgical gauze 1 can be those commonly used in surgical operations, etc., and are not particularly limited.

[0022] As shown in FIG. 2, the surgical gauze supply device 20 includes a casing 3 in which the surgical gauze assembly 10 is housed, and a gauze stopper 4. Here, the surgical gauze assembly 10 is housed in the casing 3 while being housed in a housing body 5 such as a paper box. The housing body 5 is provided with an opening 5a for taking out the surgical gauze 1, and the opening 5a serves as an extraction port 6 of the casing 3 when the housing body 5 is housed in the casing 3, which will be described later. are placed in matching positions. The opening 5a is closed by a closing member 5b before using the surgical gauze, and is configured to be opened immediately before use. That is, until use, the surgical gauze assembly 10 is sealed within the container 5. By storing the surgical gauze assembly 10 in the container 5 in this way, it is possible to easily replenish the surgical gauze assembly 10 in the casing 3, which improves ease of handling, speed, etc. You can improve your performance. Further, even when the top of the casing 3 is left open for convenience when replenishing the surgical gauze assembly 10, contamination from falling bacteria can be prevented and hygiene can be improved. Furthermore, by closing the opening 5a with the closing member 5b until just before use, hygiene can be further improved. In addition, the surgical gauze aggregate 10 is stored in the container. When storing the product directly in the casing 3 without storing it in the casing 3, the upper part of the casing 3 should not be left open and a lid or door that can be opened and closed should be provided to prevent contamination from the falling bacteria. is preferred.

[0023] The casing 3 is provided with an outlet 6 for removing the surgical gauze 1. Here, a pleated flexible member 6a serving as a resistance imparting portion is attached to the peripheral edge of the outlet 6 so as to impart resistance to the insertion and removal of the surgical gauze 1. Here, the resistance imparting part can also be attached to the opening 5a of the container 5 instead of the outlet 6. The gauze stopper 4 is configured to be able to restrict the withdrawal of the surgical gauze 1 at a position separated from the outlet 6 by a predetermined distance. Here, "a position separated by a predetermined distance" means a position separated by a distance sufficient to form a space where the surgical gauze 1 pulled out from the outlet 6 can be picked up with fingers. .

[0024] As shown in detail in FIG. 3, the gauze stopper 4 has a pair of stopper pieces 4a and 4b that are arranged opposite each other, and a gap 4c between the stopper pieces 4a and 4b has a slit shape. It has become. Further, one end side of the stopper pieces 4a, 4b is an open end 4d, and the open end 4d is tapered. The gap 4c between the stopper pieces 4a and 4b is dimensioned to allow the connecting thread 2 to pass through, but to prevent the surgical gauze 1 from passing through.

[0025] Next, a method of using the surgical gauze assembly 10 and the surgical gauze supply device 20 having the above configuration will be described based on FIG. 4.

[0026] First, the surgical gauze assembly 10 housed in the container 5 in a stacked state is housed in the casing 3 (FIG. 4(a)). Note that before housing the container 5 in the casing 3, the closing member 5b blocking the opening 5a is removed. Then, the leading surgical gauze la of the surgical gauze assembly 10 housed in the casing 3 is taken out from the opening 6 (Fig. 4 (b)). Here, since the flexible member 6a of the extraction port 6 provides resistance to the insertion and removal of the surgical gauze, when the surgical gauze la is taken out, resistance is applied to the surgical gauze la being taken out. Surgical gauze LA is removed in a spread state. Furthermore, if you pull the first surgical gauze la out further, the next surgical gauze lb will partially come out from the outlet 6. Here, when the next surgical gauze lb tries to come out from the outlet 6, the above-mentioned resistance is applied, so that the resistance force and the leading surgical gauze la are pulled. Due to the tension, the surgical gauze la is stretched diagonally.

[0027] Then, the connecting thread 2 connecting the removed surgical gauze la and the following surgical gauze lb is placed in the gap 4c between the pair of stopper pieces 4a and 4b of the gauze stopper 4. (Figure 4(c)). Here, since one end side of the stopper pieces 4a, 4b is an open end 4d, the connecting thread 2 can be freely received into the gap 4c from the open end 4d. Furthermore, since the open end 4d is tapered, the connecting thread 2 can be easily guided into the gap 4c.

[0028] As described above, the connecting thread 2 is placed in the gap 4c, and the first surgical gauze la is pulled in the direction away from the extraction port 6. Then, the gap 4c is so dimensioned that the connecting thread 2 cannot be passed through, and the next surgical gauze lb is sized so that it cannot be passed through, so the next surgical gauze 1b is removed by the gauze stopper 4. movement away from the target is prevented (Figure 4(d)). Due to this state force, when the leading surgical gauze la is further pulled in the direction away from the opening 6, the connecting thread 2 is connected to each surgical gauze 1 so that it is cut with a predetermined force. The connecting thread 2 connecting the first surgical gauze la and the following surgical gauze lb is cut, and the first surgical gauze la can be separated from the surgical gauze assembly 10 and used. (Figure 4(e)). Note that, as described above, at this time, the surgical gauze la is cut off while extending diagonally.

[0029] As described above, since the first surgical gauze la is cut, the next surgical gauze lb becomes the first surgical gauze lb, and becomes the next surgical gauze lb to be used. Here, since a flexible member 6a is provided around the periphery of the outlet 6, the first surgical gauze lb may be re-immersed in the casing 3, and the gauze may be used next time. What would happen if it became difficult to remove?

[0030] The above operations are repeated until all the surgical gauze aggregates 10 in the casing 3 are used up, and if necessary, new surgical gauze aggregates 10 housed in the container 5 can be replenished. can.

[0031] Although the embodiments of the present invention have been described above, the present invention is not limited to these, and various changes can be made without departing from the spirit of the present invention.

[0032] For example, in the above embodiment, the connecting thread 2 is cut by applying a predetermined force. As shown in Figure 5(a), the cutter blade 7 is provided on at least a portion of the edge defining the gap between the stopper pieces 4a, 4b. There is no need to do so. That is, in the embodiment described above, the leading surgical gauze la is separated from the surgical gauze assembly 10 by pulling it in the direction away from the outlet 6. By providing the cutter blade 7, the connecting thread 2 is cut into a gear. The surgical gauze la can be easily separated from the surgical gauze assembly 10 by cutting with the cutter blade 7. Here, the cutter blade 7 can be attached separately, or can be formed into a cutter blade 7 by forming at least a portion of the edge into a shape. Note that, as shown in FIG. 5(b), the open end 4d can be made larger by changing the ratio of the tapered open end 4d and the slit-like gap 4c.

[0033] Furthermore, although the gap 4c between the stopper pieces 4a and 4b is slit-shaped in the above embodiment, it can also be V-shaped (see FIG. 6). In this case, a part of the bottom edge of the gap 4c is used as the force cutter blade 7.

[0034] As described above, by making the gap between the stopper pieces into a slit shape and providing a cutter blade, or by making the gap between the stopper pieces into a V-shape and using a part of the bottom edge as a cutter blade. , can prevent injury from the cutter blade.

[0035] Furthermore, the surgical gauze supply device 20 may be configured to be fixed to the operating table using a fixing means. As the fixing means, a clamping means is provided at the lower part of the casing 3, or a fixing ring is provided at the lower part of the casing 3, and a known clipping means is provided on the sterile cloth which is usually arranged to cover the operating table. Examples include holding it in place.

[0036] In the above embodiment, the flexible member 6a is used as the resistance imparting portion that provides resistance to the insertion and removal of the surgical gauze 1. By adjusting the dimensions of the force extraction port 6, the resistance to the insertion and removal of the surgical gauze 1 is controlled. Alternatively, resistance may be applied. Furthermore, by adjusting the width of the gap 4c between the stopper pieces 4a and 4b so that the connecting thread 2 is held in the gap 4c, it may be configured to provide resistance to the insertion and removal of the surgical gauze. .

[0037] Furthermore, the gauze stopper 4 can be connected to the casing 3 by a hinge 8 and configured to be foldable. Note that the gauze stopper 4 should have a shape that follows the shape of the casing 3 when folded (see Figure 7).

[0038] Furthermore, in the above embodiment, the surgical gauze assembly 10 within the casing 3 is folded. To prevent the surgical gauze from becoming bulky, each surgical gauze 1 is folded in half (Figure 8 (a)) or in quarters (Figure 8 (b)), etc., as shown in Figure 8. The overall size of the surgical gauze assembly 10 may be reduced to such an extent that it does not get tangled within the casing 3 (receiving body 5) by folding it into two shapes.

Furthermore, in the above embodiment, when the surgical gauze aggregate 10 in the casing 3 is used up, the force of replenishing the surgical gauze aggregate 10 with a new surgical gauze aggregate 10 in the casing 3 is increased. The surgical gauze supply device 20 itself may be replaced. In this case, since there is no need to replenish the surgical gauze assembly 10, there is no need to provide any opening other than the opening 6 in the casing 3 as in the above embodiment.
