関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical expulsion hook (hereinafter abbreviated as a "retractor"), and more specifically, to excluding even relatively soft organs during laparoscopic surgery. The present invention relates to the structure of a retractor that secures a surgical field of view.

るためにリトラクターが用いられる。2. Description of the Related Art For example, laparoscopic cholecystectomy is performed in 1988.
In recent years, many laparoscopic surgeries that do not rely on laparotomy have been performed. However, unlike laparotomy, laparoscopic surgery is inherently difficult to secure a sufficient surgical field of view. In addition, unlike open surgery, laparoscopic surgery may move the liver, omentum, or intestinal tract during the operation, often obstructing the surgical field of view. A retractor is used to secure.

As shown in FIG. 4, the apparatus is roughly divided into a tip opening / closing portion 1, a rod portion 2, and a rod portion 3. It consists of a grip. Then, by gripping the grip portion 3, the inner rod 4 in the rod portion 2 is pushed (sliding toward the left side in the drawing), and the opening / closing portion 1 is opened to form a spatula of a predetermined size. 5 shows a state in which the opening / closing section 1 is closed, and FIG. 6 shows a state in which the opening / closing section 1 is opened. 10a, 10b, 11a and 11b are movable shafts, and 12 is a tip of the inner rod 4. The connecting rods 13 and 13 indicate connecting portions.

となり、先端に鋭角部分を生じる等の問題点があった。Although the conventional retractors are constructed as described above, none of them are sufficient for excluding soft organs. That is, when this type of retractor is inserted into the abdominal cavity, it is desirable to have a rod shape that has as few protrusions as possible and has no sharp edge portion at the tip, and when excluding, it also has no sharp edge portion at the tip, and Since it is necessary to apply pressure to the entire object to be evacuated, it is desirable to use a flat plate that is not transparent in the open state, but any conventional retractor has a large transparent gap in the open state. Therefore, although there is no problem in excluding the hard organs such as the liver, when excluding the relatively soft organs such as the intestinal tract, the organs protrude from the gaps and cannot be used. The gap between the shafts is the largest in the retractor shown in FIG. 7, and the retractor shown in FIGS. 4 and 8 is formed to have a support in the central portion, so it is smaller than the retractor shown in FIG. However, neither retractor can be used to exclude soft organs. In addition, the retractor shown in FIG. 4 has a problem in that, as shown in FIG. 6, the movable shafts 10a, 10b, 11a, 11b have a semi-cylindrical shape in the opened state, resulting in an acute angle portion at the tip, as shown in FIG. there were.

It is an object of the present invention to provide a medical exclusion hook that forms a flat plate-shaped whisker in the open state.

Is a diagram showing the open / close unit in the open state, and FIG. 2 is a diagram showing the open / close unit in the closed state. The configurations of the rod portion 2 and the grip portion 3 are the same as those of the conventional retractor shown in FIG.

幅を小さくしておけば良い。As shown in FIG. 1, a medical push-pull (retractor) of the present invention has an opening / closing part 1 which opens to form a whirlpool.
It is configured by stacking a plurality of flat plates 20a to 20g that open in a fan shape. This flat plate is usually formed of a metal plate having a length of about 5 cm, and a structure of 6 or 7 sheets seems to be suitable from the shape and size thereof. In addition, as shown in FIG. 2, when the opening / closing part 1 is closed when it is inserted into the abdominal cavity, the width of the flat plate is determined so that the flat plate has a diameter of 5 mm or less. In order to form a columnar shape in the closed state, as shown in FIG. 2, the width of each flat plate is set to the flat plate at the center (for example, 20d, 2
0e) has the largest width, and the width may be made smaller toward both ends.

ことは言うまでもない。The medical pressure-removing hook (retractor) of the present invention is constructed as described above, and the inner rod 4 in the rod portion 2 is fixed by gripping the grip portion 3 similarly to the conventional device shown in FIG. When pressed, the opening / closing part 1 opens and a plurality of flat plates 2
0a to 20g form a fan-shaped flat plate with no gaps. Note that the gist of the present invention is that a plurality of flat plates 20a to 20 are used.
Although it is to form a fan-shaped whirlpool with g, and its mechanism is not limited, as shown in 30 of FIG. 3, when each flat plate is opened, an elliptical hole with a constant curvature and a protrusion are formed. If the structure is such that the fulcrum of each flat plate moves like a diaphragm of a camera by combination, a fan-shaped whirlpool of a predetermined size can be smoothly developed even if the movement amount of the inner rod 4 is small. Further, it goes without saying that the opening angle can be adjusted to adjust the spread area of the fan-shaped whirlpool by adjusting the gripping amount of the gripping portion 3.

る等の効果がある。As described above, the medical pressure-removing hook of the present invention has a structure in which a plurality of flat plates open in a fan shape. It can be configured unchanged, and when it is opened in the abdominal cavity, it can form a flat plate-shaped whisker that does not have an acute angle part, and even when used for excluding a soft organ, there is no concern that the organ will stick out from the gap, and There is an effect that the organs can be excluded by a uniform pressure.
