That is, the above-described lung disease treatment device 1 is provided in a set form, so that it can have versatility.

As shown in FIG. 4, the thoracic cavity insertion device 10 according to an embodiment of the present invention may largely include a penetration unit 100, a leak prevention unit 200, and a pressurization unit 300.

The penetrating unit 100 passes through the skin surface (P6), fat (P5), and muscle (P4), penetrates the parietal pleura (P2) in the body, is disposed in the thoracic cavity (P3), and passes through the duct formed in the penetrating unit (100). When discharging body fluid or air in the thoracic cavity (P3) through the thoracic cavity (P3) internal pressure check device as shown in FIG. 1, the leakage prevention unit 200 is a penetrating unit ( By being disposed and expanded on the outer peripheral surface of the pierced pleura (P2), it is possible to prevent body fluid or air from leaking through the gap between the inner peripheral surface of the pierced parietal pleura (P2) and the outer peripheral surface of the penetrating unit 100.

That is, the penetrating unit 100 forms a conduit through which body fluid and air present in the thoracic cavity (P3) are discharged, penetrating the parietal pleura (P2) in the body and forming the visceral pleura (P1) and parietal pleura (P2) surrounding the outside of the lung. It can be placed in the thoracic cavity (P3) in between.

At this time, the penetrating unit 100 is made of a flexible material and can form a path through which body fluid or air is discharged in various directions from the point where it is inserted into the body.

The above-described penetrating unit 100 may include a needle 101 and a chest tube 102 having a duct 102a, for example, referring to FIG. 15, which will be described later.

Here, the needle 101 passes through the skin layer, fat (P5) layer, and muscle (P4) layer to reach the chest cavity (P3), and penetrates the chest cavity (P3) so that the chest tube 102 can be located in the chest cavity (P3). It is formed long, and one end may have the shape of a tip.

At this time, the needle 101 may have a spherical handle formed on the other end opposite to the tip-shaped end so that the user can hold it and remove it from the chest tube 102.

The chest tube 102 may be formed with a conduit 102a for discharging body fluid and air in the thoracic cavity P3, and the above-described needle 101 is inserted into the conduit 102a so that one end of the tip protrudes. It can be.

In other words, the chest tube 102 may be in the form of a hollow tube formed long in the longitudinal direction of the needle 101 described above and with a tube 102a formed at its center.

In addition, the chest tube 102 may include a hard needle part at one end, and the needle fixing part has only the tip of the needle 101 protruding to the outside of the chest tube 102, and one end is in the tube 102a. In order to prevent it from falling off, it may be made of a hard material.

The penetration unit 100 is described as an embodiment of being disposed in the chest cavity (P3) as shown in the drawing, but if it can perform the function of discharging body fluids or air to the outside as described above, it can include the lungs or abdominal organs in the animal's body. Even if it is placed at any position between the body wall surrounding the internal organ and the internal organ, it will all be said to fall within the scope of the present invention.

For example, the penetrating unit 100 may be a chest tube or a trocar.

Next, the leak prevention unit 200 is disposed on the outer peripheral surface corresponding to the diameter of the above-described penetration unit 100, receives external force from the pressurizing unit 300 to be described later, and penetrates the parietal pleura (P2) by the external force. By expanding and being fixed toward the inner surface and the opposite outer skin surface (P6), it is possible to prevent body fluid in the thoracic cavity (P3) from leaking into the gap between the pierced parietal pleura (P2) and the penetrating unit (100).

In other words, the penetrating unit 100 forms a perforation in the parietal pleura (P2), and a gap may occur between the outer circumferential surface of the penetrating unit 100 fixed to the parietal pleura (P2) and the inner circumferential surface of the perforation. In this case, body fluid or air may form. At the same time as it is discharged to the outside through the penetrating unit 100, it may leak toward the outer muscle (P4) and fat (P5) of the parietal pleura (P2) through the above-mentioned gap.

To prevent this, the leak prevention unit 200 passes through the inner surface of the parietal pleura (P2) facing the lung among the above-mentioned organs, the outer muscle (P4) and fat (P5) of the parietal pleura (P2), and the skin surface (P6). ), and expands by receiving external force from the pressurizing unit 300, thereby stably fixing the penetrating unit 100 to the parietal pleura P2 and simultaneously closing the above-mentioned gap.

Here, the leak prevention unit 200 is coupled to the outer peripheral surface of the penetrating unit 100 and expands. If it can be connected to contact the outer peripheral surface corresponding to the diameter of the penetrating unit 100, it is positioned in the longitudinal direction of the penetrating unit 100. is not limited, and as a result, it is natural that the scope of rights of the present invention is not limited.

However, for more detailed explanation, if the position of the leak prevention unit 200 on the penetrating unit 100 is explained as an example, the leak prevention unit 200 has one end on the wall side corresponding to the depth at which the penetrating unit 100 is inserted. It can be simultaneously expanded toward the pleura (P2) and at the other end toward the skin surface (P6).

For example, as shown in FIG. 3, the leak prevention unit 200 is provided at the center of the penetrating unit 100, so that one end faces the parietal pleura P2 and the other end expands simultaneously towards the skin surface P6. .

In addition, when pushing the penetrating unit 100 up to the tip of the lung, the leakage prevention unit 200 may be provided on the penetrating unit 100 rear than the position shown in FIG. 3, and the penetrating unit 100 can be pushed briefly. In cases where it is acceptable, it may be arranged to be located ahead of the position shown in FIG. 2 on the penetrating unit 100.

Specifically, the leak prevention unit 200 may include a body portion and an expansion portion 220.

The body portion is coupled to the outer circumferential surface of the penetrating unit 100 described above, and may be connected to contact the outer circumferential surface corresponding to the diameter of the penetrating unit 100.

Additionally, the body portion may have an internal space to form a space into which the expansion part 220, which will be described later, can be inserted or expanded.

In addition, the body portion expands to a certain thickness according to the expansion of the expansion portion 220, which will be described later, and can be firmly fixed between the pierced skin surface (P6), fat (P5), and muscle (P4) as shown in FIG. It can be said that it is natural that it exists.

As shown in FIG. 4, the expansion portion 220 has one end and the other end embedded in the above-described body part, and is directed toward the parietal pleura P2 at one end and toward the skin at the other end by the external force of the pressurizing unit 300, which will be described later. It can expand simultaneously toward face (P6).

In summary, the expansion part 220 and the body part are provided as an integrated piece, and the expansion part 220, which is depressed at one end and the other end of the body part, can be expanded by receiving the external force of the pressurizing unit 300 on one side.

In addition, the leak prevention unit 200 having the above-described configuration is embedded inside the expansion part 220 as shown in FIGS. 6 and 7, and when the expansion part 220 expands, it moves in one direction. By standing up, the leak prevention unit 200 further includes a shape limiting part 240 that limits the expansion of the expansion part 220 toward the parietal pleura (P2) and the skin surface (P6), so that the leak prevention unit 200 is expanded beyond a preset area. If it is damaged or removed, you can prevent it from falling out.

At this time, the pressurizing unit 300 may transmit external force to the leak prevention unit 200 described above to expand the leak prevention unit 200.

If the pressurizing unit 300 can expand the leakage prevention unit 200 without supplying a passage or fluid for expansion, its structure, material, and method may vary, and all are said to fall within the scope of the present invention.

However, for more detailed explanation, an example is given in detail as follows.

As shown in FIG. 8, the pressurizing unit 300 expands the leak prevention unit 200 without adding any components to the interior of the leak prevention unit 200 by pressurizing only one side of the leak prevention unit 200. It may be provided to slide on the outer peripheral surface of the penetrating unit 100.

In addition, although not shown in the drawing, a plurality of irregularities are formed on the outer peripheral surface of the penetrating unit 100 arranged along the longitudinal direction of the penetrating unit 100, and the pressurizing unit 300 slides along them to secure the leakage prevention unit 200. It may be arranged to expand gradually.

In addition, a female thread is formed along the longitudinal direction of the penetrating unit 100 on the outer peripheral surface of the penetrating unit 100, and a correspondingly formed male thread is formed on the inner peripheral surface of the pressing unit 300, thereby allowing the pressing unit 300 to rotate. It may be arranged to advance toward the leak prevention unit 200 and pressurize it.

Although not shown in the drawing, the chest cavity insertion device 10 having the above-described configuration further includes a heating unit, so that when the pressurizing unit 300 transmits external force to the leakage prevention unit 200, the inside of the leakage prevention unit 200 It may be provided to assist expansion of the leak prevention unit 200 by increasing the temperature.

Furthermore, the thoracic cavity insertion device 10 having the configuration described above further includes a drying unit, so that when the pressurizing unit 300 releases the external force, the internal temperature of the leak prevention unit 200 is lowered, thereby forming the leak prevention unit ( 200) may be provided to assist in releasing the inflation.

Next, another example in which the leakage prevention unit can be expanded without supplying a flow path and fluid for expansion will be described as an example as follows.

As shown in Figure 9, the thoracic cavity insertion device 10-1 according to another embodiment of the present invention may largely include a penetration unit 100, a leak prevention unit 400, and a pressurization unit 500, where Since the penetrating unit 100 is identical and similar to the penetrating unit 100 according to an embodiment of the present invention, the same drawing number will be assigned and the description will be omitted.

Next, the leak prevention unit 400 may include a body portion and an expansion portion 420 as described in an embodiment of the present invention, which includes a body portion and an expansion portion 420 according to an embodiment of the present invention. ), so we will omit the description of its structure and function and only explain the other parts.

However, since it may be confused with an embodiment including the link unit 460, which will be described later, the illustration will be described by assigning different numbers.

The leak prevention unit 400 may include a body part and an expansion part 420 as shown in FIG. 10, and as shown in FIG. 11, the inside of the expansion part 420 has a shape similar to one embodiment. It would be natural that the restriction unit 440 can be provided.

In addition, as shown in FIG. 12, the thoracic cavity insertion device 10-2 according to another embodiment of the present invention may largely include a penetration unit 100, a leak prevention unit 400, and a pressurization unit 500. , Here, since the penetrating unit 100 is identical and similar to the penetrating unit 100 according to an embodiment of the present invention, the same drawing number will be assigned and the description will be omitted.

The leak prevention unit 400 according to another embodiment of the present invention may further include a link portion 460.

Here, as shown in FIG. 13, the link portion 460 may be provided inside the body portion so that one side is moved by an external force and the other side expands the expansion portion 420.

Here, if the link part 460 receives an external force by the pressurizing unit 500 and the structure is variable so that the expansion part 420 can be expanded, the structure and material may vary, which is within the scope of the present invention. It would be natural to say that there are no restrictions.

However, for more detailed explanation, as an example, the link unit 460 may include a base 461, moving members 462, 464, 466, and folding members 468 and 469, as described in FIG. 13. In this case, the folding member A shape limiter 440 may be connected to the ends of (468, 469).

The base 461 may be fixed to the outer peripheral surface of the chest tube of the penetrating unit 100 corresponding to the diameter of the penetrating unit 100 in the form of a hollow tube.

A plurality of moving members 462, 464, 466 may be provided to move together along the longitudinal direction of the above-described base 461. For example, a plurality of moving members 462, 464, 466 may be divided into a plurality of spaced apart shapes (462, 464, 466) to form a base 461. ) may be provided to slide on, and may be connected to folding members 468 and 469, which will be described later, and may be provided to move together on the base 461.

The folding members 468 and 469, like umbrella spokes, may be connected to the moving members 462, 464, and 466 and may be arranged to unfold toward the expansion portion 420 or return to the original position as the moving members 462, 464, and 466 move.

At this time, as shown in FIG. 14, the pressing unit 500 generates magnetic force to move any one of the above-described moving members 462, 464, and 466, and the folding members 468 and 469 can be arranged to unfold or fold in response. there is.

For example, the pressing unit 500 may be made of an electromagnet, and the moving member 462 closest to the pressing unit 500 may be made of a permanent magnet or a ferromagnetic material.

Therefore, as the pressurizing unit 500 is provided to generate or release magnetic force on the outer peripheral surface of the penetrating unit 100, the adjacent moving member 462 provided on one side of the link portion 460 moves and interlocks with the other moving member 462. As the moving members 464 and 466 are also moved, the folding members 468 and 469 are unfolded as shown in the drawing and the leakage prevention unit 400 can expand.

At this time, as described above, a shape limiting portion 440 may be provided on the folding members 468 and 469. At this time, the shape limiting portion 440 not only limits the expansion area of the leakage prevention unit 400, but also restricts the folding members 468 and 469.
