Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cover that protects the incision from invading bacteria during incisional surgery.

[Conventional technology]

For example, when performing open surgery, the surgical field and the surrounding skin are disinfected and the area around the incision is covered before a scalpel is inserted.

However, even if the skin surface is disinfected, it is difficult to completely sterilize the sweat glands and sebaceous glands. Therefore, over time, there is a risk that resident bacteria may migrate and adhere to the cut.

In order to eliminate these problems, conventionally, as shown in FIG.
A flexible film 2a (for example, urethane film) is pasted onto (skin, subcutaneous fat, abdominal muscles, peritoneum) via an adhesive 2b. Then, when the film 2a is cut together with the scalpel 3, the sixth
In the state shown in the figure, resident bacteria are expelled from the skin surface along with sweat and are prevented from entering the incision 1a.

[Problem that the invention seeks to solve]

However, since various types of resident bacteria inhabit the abdominal cavity, there is a possibility that these resident bacteria may invade the incision 1a. Furthermore, there is no guarantee that resident bacteria floating in the air will not invade the cut 1a.

SUMMARY OF THE INVENTION The present invention provides an incision cover that can immediately cover the cut end of an incision to prevent the invasion of resident bacteria, and can be quickly and easily attached and removed.

[Means for solving problems]

In order to achieve the above object, the incision cover of the present invention has a cylindrical member made of a plastically deformable and flexible thin film, and a ring-shaped member that is elastically restored to its original shape is attached to each end of the cylindrical member.

Then, the length of the cylindrical member in the state in which the annular member is attached as described above is 1/2 or less of the diameter of the annular member.

Further, if necessary, the cylindrical member to which the ring member is attached as described above is sterilized and packaged.

[Effect]

The cover configured as described above has a ring-shaped member that elastically restores its shape attached to each end of the cover, so one of these ring-shaped members can be compressed to make an incision. When inserted into the abdominal cavity, it elastically restores its shape within the abdominal cavity and becomes ring-shaped. The other end of the cylindrical portion is located outside the incision and is pushed apart by a ring-shaped member, so that the incision is covered with a cylindrical thin film and protected from bacteria. Moreover, since the diameter of the annular member is more than twice the length of the cylindrical member, when each of the pair of annular members expands into an annular shape due to elasticity, the cut ends of the cylindrical member This allows the surgeon to widen the area and facilitate the surgery.

Embodiment FIGS. 1 and 2 show an embodiment of the present invention,
FIG. 1 is a longitudinal sectional view, and FIG. 2 is a perspective view.

The thin cylindrical member 4 is made of a flexible material that is easily plastically deformed (for example, latex, elastic film, etc.).

Although the cylindrical member 4 itself has no directionality, for convenience of explanation, it will be described below according to the top and bottom in the usage state.
The upper and lower parts are distinguished and called. This top and bottom can be reversed.

A ring-shaped member 5a having an elastic restoring force is attached to the lower end of the cylindrical member 4, and a ring-shaped member 5b is attached to the upper end of the cylindrical member 4.
Each is fixed.

The ring-shaped members 5a and 5b in this example are made of rubber. When carrying out the present invention, an appropriate material can be selected and used for the above-mentioned ring-shaped member that has a property of elastically returning to its ring shape. 1st
As shown in FIGS. 2 and 2, when the annular member 5b is attached to both ends of the cylindrical member 4, the length L of the cylindrical member is 1/2 of the diameter D of the annular member.
Set it as follows.

To use the cover configured as above,
As shown in FIG. 3, the lower ring-shaped member 5a is compressed and deformed, inserted into the incision 1a as shown by arrow A, and released. As shown in FIG. 4, the ring-shaped member 5a becomes elastic within the abdominal cavity. The incision is then expanded and covered with a cylindrical member 4, which isolates it from bacteria. Since the cylindrical member 4 is thin and made of a flexible material that is easily plastically deformed, it adapts well to the elastic expansion of the annular member 5a and fits closely to the incision. Detachment can be easily accomplished by reversing the above procedure. When the incision cover of this embodiment is attached to the incision as shown in FIG. When expanded into a ring shape due to its own elasticity, both upper and lower ends of the cylindrical member 4 are pulled up in the left-right direction in the figure. the result,
The cylindrical member 4 widens the incision opening and maintains it in a condition that facilitates surgery.

Cover configured as described above (Figures 1 and 2)
should be sterilized and packaged. This is because it can be attached to the incision site immediately after opening the package.

〔Effect of the invention〕

As described in detail above, when the present invention is applied, the incision can be immediately covered to prevent bacteria from entering, and the incision can be automatically expanded to maintain a state in which surgery is easy. Can be quickly and easily attached and detached.
