DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical airtight holding device for maintaining a small incision site closed and temporarily maintaining airtightness in a body cavity mainly in surgical treatment.

[0002]

2. Description of the Related Art In recent years, laparoscopic surgery has rapidly spread, and its indications are also expanding. In laparoscopic surgery, it is necessary to provide a space in the abdominal cavity in order to secure an operation field, and two methods, a pneumoperitoneum method and a lifting method, have been widely used as means for that.

[0003] The pneumoperitoneum is a technique in which carbon dioxide gas is supplied into the abdominal cavity through a pneumoperitoneal needle punctured into the abdominal cavity, thereby inflating the abdominal cavity in a tent shape. On the other hand, in the lifting method, a visual field is developed by passing a metal wire or the like under the skin or all layers and lifting the entire wire. Although each method has merits and demerits, since the visual field and the operability are different, the insufflation method and the lifting method are selectively applied depending on the target region, the operative method, and the like. (Advantages and problems of the abdominal wall lifting method in laparoscopic surgery: JSES 1996. p. 223-
p227)

Normally, laparoscopic surgery can be performed by only one of these methods, but it cannot be performed under the pneumoperitoneum, such as a peeling operation, due to the expansion of the surgical procedure. The technique of performing a complicated operation through a small incision by the lifting method has also been found particularly in operations on the small intestine. In this case, it is easy to switch from the insufflation method to the lifting method.

However, a necessity arises, and in order to return from the lifting method to the pneumoperitoneum method, the small incision must be re-sewn to maintain the airtightness. For this reason, it was a very time-consuming and time-consuming method.

[0006] As a method for solving this problem, a screw is formed by sandwiching the abdominal wall from inside and outside by a movable metal disk disposed on a metal rod and two semi-disks which become one disk by sliding. The airtight holding device for fixing with the above components has been devised and put into practical use. However, not only is it difficult to insert because the disc diameter is fixed, it can not cope with the difference in incision size, there is a possibility that the visual field in the abdominal cavity can be narrowed due to the weight, and it is exposed outside the abdominal wall It is possible that the fixation mechanism interferes with the progress of the operation.

[0007]

SUMMARY OF THE INVENTION The present invention has been made as a result of various studies in order to solve such a problem of a method of switching from a small incision surgery in a conventional laparoscopic surgery. , Of course, to keep the airtight inside the body cavity,
The simplified method of fixing the airtight plate can shorten the time for switching between surgical procedures, can respond to differences in the size of the incision, and provide medical treatment that does not hinder the operator's movement due to unnecessary projections It is an object of the present invention to provide a device for maintaining airtightness in a body cavity.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings. FIG. 1 is a schematic view showing an embodiment of a device for maintaining airtightness in a body cavity according to the present invention. FIG. 1A shows an example of a configuration, FIG. 2A shows an example of use in airtightness maintenance in an abdominal cavity, and FIG. Shows an example of a method of fixing the fixing thread (3) and the fixing plate (2), and FIG. 3 shows an example of a method of inserting the airtight plate (1) into the small opening (6).

[0010] The body cavity airtight holding device of the present invention covers a small incision opening (6) from the inside of the body cavity and has a flexible airtight plate (1) for keeping the inside of the body cavity airtight. It is composed of a fixed thread (3) connected thereto and a fixed plate (2) for fixing the fixed thread (3) outside the body cavity.

The airtight plate (1) is made of a flexible material such as natural rubber, silicone rubber, soft vinyl chloride resin or polyurethane resin, and has sufficient strength to maintain airtightness and sufficient operability. 0.1 to 10.0 to obtain
mm is desirable. The shape is preferably circular or oval in order to avoid bleeding and organ damage, and from the viewpoint of cost and operability. Considering that the area needs to be large enough to cover the small opening (6) and the operability, it is desirable that the diameter is 1-2 times the length of the small opening (6). Depending on the case, a reinforcing component (7) may be attached to maintain airtightness. The surface shape may be flat, or a groove may be provided to increase the contact area to ensure higher airtightness.

The fixing plate (2) has a fixing groove (4) for fixing the fixing thread (3). Since the fixing groove (4) is fixed by caulking the fixing thread (3), it is desirable that the shape is simply parallel or tapered from the viewpoint of productivity. The minimum width of the fixing groove (4) is the fixing thread (3).
The width is desirably as small as possible, preferably 20 to 80% of the diameter of the fixed yarn (3), more preferably 3 mm.
A range of 0 to 50% is desirable from the viewpoint of productivity. The number of the fixing grooves (4) is not particularly limited as long as a sufficient fixing force can be obtained. Desirably. The thickness of the fixing plate (2) may be any thickness as long as sufficient strength can be obtained.
0 mm is desirable. The shape is not particularly limited, but a circular or oval shape is appropriate in order to avoid harming the body due to the angular shape and from the viewpoint of operability. The size must be large enough to cover the small opening (6), and preferably the same size as the airtight plate (1) is desirable in terms of operability and airtight maintenance. The material is preferably a hard material such as a hard vinyl chloride resin or an ABS resin since sufficient strength can be obtained, but it is not necessary to limit the material to such a material.

The number of the fixing yarns (3) is not particularly limited as long as a sufficient fixing force can be obtained. However, the number of the fixing yarns (3) does not damage the small opening unnecessarily, balances them, and fixes the fixing groove (4).
It is desirable that the number be one to three in order to communicate with each other. The fixing thread (3) is fixed to the airtight plate (1) by passing the fixing thread (3) through the airtight plate (1) once and fixing it by tying a knot, or by penetrating it twice and forming a loop. It is appropriate from the viewpoint of productivity that the fixing is performed in a fixed manner, but the method is particularly limited as long as sufficient strength is obtained and the fixing thread (3) and the fixing groove (4) communicate with each other. Not done. The thickness of the fixing thread (3) is not particularly limited, but is preferably about 0.3 to 8.0 mm in diameter, in order to maintain strength and not to unnecessarily expand the small opening (6). Is preferably 0.5 to 2.0 mm. The fixing yarn (3) is preferably a twisted yarn or a knitting yarn in order to obtain a sufficient fixing force for combing the fixing groove (4), but is not limited to this.

When the airtight plate (1) is inserted into the small opening (6), the airtight plate (1) is larger than the small opening (6). Insert with reduced dimensions. After insertion, the airtight plate (1) returns to its original shape in the abdominal cavity and covers the small opening (6). This is brought into close contact with the abdominal wall (5) by pulling the fixing thread (3), and maintaining the pulled state by the fixing plate (2) to maintain airtightness in the abdominal cavity.

The fixing thread (3) is fixed by caulking the fixing thread (3) in the fixing groove (4) of the fixing plate (2).
Preferably, while holding the fixing plate (2) against the abdominal wall (5), the fixing thread (3) is crimped into the fixing groove (4) of the fixing plate (2) while being pulled. As a result, the airtight plate (1) in the abdominal cavity closely adheres to the abdominal wall (5), and sufficient airtightness can be obtained.

At the time of removal, by removing the fixing thread (3) from the fixing groove (4), the fixing between the fixing plate (2) and the airtight plate (1) is easily released, and the airtightness in the abdominal cavity is released. You. The airtight plate (1) in the abdominal cavity can be easily taken out because of its flexibility.

[0017]

As described above, the use of the medical device for maintaining airtightness in a body cavity according to the present invention not only can maintain airtightness in the body cavity but also can be easily attached to and detached from an incision, and an airtight plate can be obtained. However, since it is a flexible material, it is possible to cope with the difference in the size of the incision, and since there are no protrusions protruding outside the body cavity, it does not hinder the operation of the operator, and is extremely useful.
