Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to surgical coverings, particularly cardiovascular surgical coverings.

[Prior Art] Conventional surgical dressings used in surgical or related procedures are large enough to cover the patient's body and have at least one window in the center for exposing the surgical area. The region of the window allows for the formation and maintenance of a sterile barrier surrounding it. That is, the area around the surgical site of the main sheet centered on the window is reinforced by a reinforced panel having a water-absorbing surface and a liquid-repellent back surface, and on both sides there are panels to prevent the external diffusion of body fluids and irrigation fluids generated during surgery. An obstacle for preventing contamination is provided, and the transparent sheet attached to the surface of the window is provided with adhesive attachment means for adhering a covering cloth to the area around the affected area including the affected area.

In addition, during surgical operations, surgical equipment corresponding to each operation is used, and in the case of cardiovascular surgery in particular, cords (wires) used for cardiac arrest, continuous infusion circuits, myocardial protection infusion circuits, and water sprinkling are used. It requires the use of various types of equipment such as pumps, bobby cords, suction tubes, etc., and it is particularly preferable that auxiliary equipment such as tubes, cords, wires, etc. attached to these devices can be easily used around the surgical site.
Various holding means for the auxiliary equipment have been proposed. For example, a sieve can be a clamp that is inserted directly through the covering fabric, a tie-holding string that is fixed to the covering fabric through a fixing sheet around the window, or a tube that has holes that penetrate through it. A holder, etc. is used, and recently a conduit is provided parallel to both sides of the window to pass the auxiliary equipment all together and hold it to the surgical site, or a conduit extending from the central lower edge of the covering to the surgical site A holding means has been proposed in which a crack is provided in place of the window, and a pocket for storing auxiliary equipment is provided at the edge of the crack.

[Problem to be solved by the invention] The above-mentioned holding means using a clamp that is inserted through the covering cloth has the risk of causing damage such as tears to the covering cloth during use, which may lead to destruction of the sterilization barrier. .

Also, when using strings, the method of attaching the strings is complicated,
It is impossible to fix a large number of auxiliary devices in desired positions.

Further, in the case of holding means using a tube holder or a conduit, it is necessary to pass an auxiliary device through the holding hole or the conduit of the holder, and the work to fix the auxiliary device in a predetermined position is complicated.

Next, a holding device for storing auxiliary equipment in a pocket along the edge of a crack created in place of a window has some effect, but there is almost no area corresponding to the area surrounding the window, and the area affected during surgery is difficult to maintain. There are no areas for absorption or retention of draining body fluids and irrigation fluids, and the retention of the sterile barrier is less than perfect.

In addition, surgical instruments such as gauze, forceps, scissors, forceps, etc. may be poured into the space between the reinforcement panel and the obstructions provided on both sides of the reinforced panel to prevent contamination during surgery, making it difficult to lose track of their whereabouts. This may hinder the smooth performance of the surgery.

The present invention can be used not only in cardiovascular surgery but also in other surgical procedures, ensuring that a sterile barrier is maintained in both cases, and that auxiliary equipment such as tubes, cords and wires are maintained in alignment at the surgical site. The object of the present invention is to provide a surgical covering that has flexible holding means and enables smooth operation.

[Means for Solving the Problems] In order to achieve the above object, the surgical covering of the present invention has a main sheet located at the center of the window for exposing the affected area. A flexible reinforced panel with an absorbent surface and an impermeable back surface is provided to reinforce a certain window area, and on each side of the panel are two strips of said anti-contamination barrier parallel to the side edges of the window. A flexible water-conducting flap is provided, and the window is provided with a transparent sheet having adhesive attachment means for adhering the covering to the area surrounding the affected area, including the affected area.

Next, as a holding means for storing and maintaining various tubes, cords, wires, etc. that are auxiliary equipment for surgical equipment, a cut section is provided at the end of the two water guiding flaps mentioned above, and the two flaps are separated by the cut section. By folding the end piece of the flap in half, the structure allows auxiliary equipment to be stored.

Further, an adhesive means is provided on the end piece of the flap.

Further, the large flaps on both sides of the main seat are provided with overlapping cut portions at the portion corresponding to the upper edge of the window, and a protruding cut portion is provided for allowing the stand for supporting surgical instruments to protrude above the cover cloth.

In addition, the water guiding flap is made of a transparent material.

[Function] As described above, the surgical covering of the present invention has a transparent sheet attached to the window forming the surgical site, and an adhesive attachment means on the back side of the transparent sheet for attaching the covering to the area surrounding the affected area including the affected area. A main sheet made of a flexible member having the window in the middle thereof is provided with a flexible reinforcing panel having a water-absorbing surface and a water-impermeable back surface in the window region around the surgical site on the axis of the main sheet. The reinforced panel is equipped with two flexible water guiding flaps on both sides to prevent contamination. Therefore, it is desirable to provide a general-purpose surgical covering that is capable of absorbing secreted body fluids and stagnation of irrigation fluid around the surgical site formed by the window area, and also capable of forming and maintaining a sterile barrier. can.

In addition, since a cut part is provided at the end (especially the upper part) of the water guiding flap, the separated end piece of the flap is folded in two to hold and store the necessary auxiliary equipment, and then further folded and then clipped, etc. If it is clamped with the fastening means, it can be held securely and efficiently.

Since adhesive means are also provided on the side surfaces of the flap end piece, in this case the auxiliary equipment can be maintained more reliably.

Also, since the large flaps on both sides of the main sheet are provided with overlapping cutouts, it is possible to obtain a stand protrusion for supporting surgical instruments that can form and maintain a sterile barrier.

In addition, since the water-conducting flap is made of a transparent material, it is possible to visually check the entire area of the surgical site during surgery, including the lower part of the flap. It is possible to eliminate the cause of troubles such as losing track of the location of surgical instruments and hindering the performance of surgery.

[Example] Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a surface view of the covering of the present invention, and FIG. 2 and FIG. 3 are diagrams showing how necessary auxiliary equipment is arranged on the end piece of the flap and then stored to form a holding means.

As shown in FIG. 1, the main sheet 1 of the surgical dressing of the present invention is made of a flexible liquid-repellent material and is large enough to cover the affected area of the patient's body. A large flap 13 made of the same material as the main sheet is provided.

A window 3 for exposing the affected area is provided in the center of the main sheet 1, and a transparent resin thin film sheet 4 having an adhesive attachment means for attaching the affected area is adhered to the back side of the window 3.

6 is a water guide flap that is fixed to the surgical site and forms an obstacle to prevent contamination, and prevents secreted body fluids from the surgically affected area and irrigation fluid from flowing out from the periphery of the surgical site to the sides, and has an adhesive attachment means. Together with the thin film sheet 4, the covering functions to form and maintain a sterile barrier. In the case of cardiovascular surgery, the body fluid and irrigation fluid are drained to the outside through a suction tube. In the case of other surgical operations, the fluid is collected in a collection bag via the water-conducting flap.

Reference numeral 6 designates a cut portion provided at the end portion of the water guiding flap 5 in order to create a holding means for storing auxiliary equipment 10 such as a tube, a cord, and a wire. Although it is provided only at the upper end in FIG. 1, it may also be provided at the lower end if necessary. Particularly in the case of cardiovascular surgery, auxiliary devices may also be used in the legs and thighs. The flap end piece 7 separated from the water guiding flap by the cut portion 6 has a crease 8 in the center as shown in FIG. 2, so that it can be folded in half while holding the auxiliary equipment 10 arranged on the lower side. It's like this. After the folding and storage, the holding means 11 for the auxiliary device 10 is formed by fastening it with the clip 12 as shown in FIG. In addition to folding the distal end piece, it is also possible to wrap the device around it.

Further, as shown in FIG. 2, if an adhesive means 9 is provided on the side surface of the flap end piece 7, the auxiliary equipment can be easily arranged and the auxiliary equipment can be reliably maintained in a fixed position after being stored.

The large flap 13 shown in FIG. 1 is provided with an overlapping cutout 14 at a portion corresponding to the upper end of the window 3.
A protrusion 15 for maintaining a sterile barrier for installing a stand for supporting surgical instruments is provided in the cut portion to make the surgery more efficient.

In addition, since the water guiding flap 5 is made of a transparent polyethylene sheet, it is possible to check the situation over the entire area of the surgical site, including the lower part of the flap 5, during the surgery. Never lose track of your equipment.

[Effects] Since the present invention is configured as described above, it produces the effects described below.

The covering cloth of the present invention is made of a flexible sheet, and has a window in the center for exposing the affected area with a transparent resin thin film sheet having an adhesive attachment means for attaching it to the human body, and the window area of the window around the surgical site is A reinforced panel with a water-absorbent surface and a water-impermeable back surface is provided, and water-conducting flaps are provided on both sides of the panel to prevent contamination, making it possible to maintain the formation of a sterile barrier. We were able to provide some surgical coverings.

In addition, the holding means for storing auxiliary equipment can be formed by bending the end pieces of the flap separated by the cut portion provided at the end of the water guiding flap, so that the storage operation is easy and the auxiliary equipment can be stored separately. The array can be maintained in a predetermined position.

Further, since adhesive means is provided on one side of the end of the flap corresponding to the storage portion, the auxiliary equipment during the surgery is not moved from its storage position, and the surgical operation can be performed without any hindrance. Furthermore, if a fastening means such as a clip is used after the end piece is bent and an auxiliary device is clamped, the holding means will function more reliably.

In addition, the large flaps provided on both sides of the covering cloth are provided with overlapping cutouts, so that the protrusion of the surgical instrument support stand for forming a sterile barrier can be provided near the surgical area by passing through the cutouts. .

In addition, since the water-conducting flap is made of a transparent material, it is possible to constantly check the entire area of the surgical site, including the lower part of the flap. It is convenient to count the number of gauze sheets without losing sight of them, and the surgery can be carried out smoothly.
