Description

Fistula treatment device and fistula treatment system using the same

[0001] The present invention relates to a fistula treatment device and a fistula treatment system using the same, and more specifically, to a fistula treatment device and a fistula treatment system using the same that allows a sponge inserted into a fistula to be easily inserted into an accurate position by means of an endoscope.

[0002]

[0003] A fistula is the formation of an abnormal tube or connection between body organs or ducts that are not normally connected. Typically, fistulas (or fistulae) can occur in various parts of the body, but they frequently occur in the digestive system, such as the esophagus and stomach.

[0004] An esophageal fistula is a hole that forms when the anastomosis site fails to heal properly after surgery; food can leak through this opening, forming an abscess, and in severe cases, can lead to sepsis and death.

[0005] The most common cause is gastroesophageal surgery, and it is an intractable disease that can recur even if the fistula is sutured through reoperation. For this reason, an alternative method other than surgery is the insertion of an esophageal stent to block the fistula.

[0006] However, stents only block food from entering through the fistula and have a high failure rate as a method of waiting for the abscess to heal naturally. Recently, endoscopic vacuum therapy (EVT) is being performed, which involves inserting a negative pressure tube and sponge into an esophageal (gastric) fistula and applying negative pressure at a strength of 125 mmHg to remove secretions from the abscess and induce fistula closure.

[0007] However, this system has the disadvantage of being cumbersome to mold by directly sewing the sponge onto the tube, and it is difficult to produce hygienically due to the risk of infection during the manufacturing process. Additionally, there are problems such as the sponge easily slipping out even after being inserted into the fistula, and the risk of loss during its movement to the fistula, which results in a time-consuming and difficult procedure with a high risk of infection.

[0035]

[0036] Hereinafter, an embodiment of the present invention as described above will be explained in detail with reference to the drawings.

[0037]

[0038] FIG. 1 illustrates a perspective view of a fistula treatment system according to one embodiment of the present invention. As shown in FIG. 1, the fistula treatment system of the present invention includes an endoscope (100) and a fistula treatment device (200) coupled to the endoscope (100).

[0039] The endoscope (100) includes a control unit (110) operated by a medical professional and an insertion tube (120) inserted into the patient's body. Although not shown in the drawing, the endoscope (100) is connected to a separate display device, and an image captured by a camera (140) installed at the end of the insertion tube (120) is output to the display device.

[0040] The fistula treatment device (200) is inserted into a channel (130) formed along the longitudinal direction inside the insertion tube (120) of the endoscope (100) and inserted into the patient's body together with the insertion tube (120) of the endoscope (100). After inserting the sponge (210) provided at the end of the fistula treatment device (200) into the fistula, the condition is such that negative pressure treatment can be performed by pulling out only the insertion tube (120).

[0041] This will be explained in more detail with reference to Figures 2 and 3.

[0042]

[0043] FIG. 2 illustrates a perspective view of a fistula treatment device of a fistula treatment system according to one embodiment of the present invention. As shown in FIG. 2, the fistula treatment device (200) of the present invention mainly comprises a sponge (210), a tube (220), and a negative pressure device coupling part (230).

[0044] The tube (220) is preferably formed from a soft material, and one or more drainage tubes widely used in the medical field may be selected and used. A sponge (210) inserted into a fistula is attached to one end of the tube (220), and a negative pressure device coupling part (230) for coupling with a negative pressure device is attached to the other end of the tube (220).

[0045] The diameter of the tube (220) is formed to be smaller than the diameter of the channel (130) formed in the endoscope (100). At one end of the tube (220), that is, the area where the sponge (210) is attached, at least one hole (221) is formed on the circumference surface, and the hole (221) is formed so that negative pressure can be applied evenly when the sponge (210) is inserted into the fistula.

[0046] The size of the sponge (210) may be formed differently depending on the size of the fistula, and a medical professional may trim the sponge (210) to correspond to the size or shape of the fistula. A treatment method using the fistula treatment system of the present invention will be described with reference to FIG. 3.

[0047]

[0048] FIG. 3 illustrates a fistula treatment flowchart of a fistula treatment system according to one embodiment of the present invention. First, as shown in FIG. 3 (a), a fistula is formed between the esophagus and the stomach of a patient based on FIG. 3. To treat this, an insertion tube (120) of an endoscope (100) is inserted into the patient's body, and the location of the fistula is tracked based on imaging data captured by a camera (140) installed at the end of the insertion tube (120).

[0049] Once the location of the fistula is tracked, as shown in FIG. 3 (b), a guide wire is connected to the channel (130) of the insertion tube (120), and then the guide wire is positioned on the side of the fistula, and the insertion tube (120) is pulled out of the body.

[0050] Next, as shown in FIG. 3 (c), the endoscope is removed from the body, and a fistula treatment device (200) is attached to the channel (130) of the insertion tube (120) and then reinserted into the body. As described with reference to FIG. 3 (b), the insertion tube (120) of the endoscope (100) enters the patient's body along the guide wire inserted into the body and moves toward the fistula.

[0051] A sponge (210) formed at the end of the fistula treatment device (200) is inserted into the fistula. Similarly, since the sponge (210) is inserted while viewing the location of the fistula with a camera (140), it is easy to insert the sponge (210) into the fistula.

[0052] Finally, after inserting the sponge (210) into the fistula and pulling the guide wire out of the body and pulling the insertion tube (120) out of the body, only the sponge (210) and the tube (220) combined with the sponge (210) remain in the body as shown in (d) of FIG. 3.

[0053] At this time, a negative pressure device coupling part (230) is coupled to the other end of the tube (220), that is, the end of the tube (220) located outside the body, and as the negative pressure device is coupled to the negative pressure device coupling part (230) and operates, secretions within the fistula are removed to enable smooth blood circulation and allow the fistula to be closed quickly.

[0054]

[0055] As described with reference to FIGS. 1 to 3, the fistula treatment system of the present invention allows the fistula treatment device (200) to be inserted into the body together with the insertion tube (120) of the endoscope (100), thereby enabling the location of the fistula to be quickly found using the camera (140) provided at the end of the insertion tube (120) and the sponge (210) to be easily inserted into the fistula.

[0056] At this time, the sponge (210) located in front of the direction of movement of the insertion tube (120) is large, and as it obstructs the area being photographed by the camera (140), the location of the fistula may not be found quickly. Therefore, to prevent this, the fistula treatment system of the present invention further includes a protective cap (300) attached to the end of the insertion tube (120). Various forms of the protective cap (300) of the present invention will be described with reference to FIGS. 4 to 7.

[0057]

[0058] FIG. 4 illustrates a perspective view of a fistula treatment system according to a first modified example of an embodiment of the present invention. As shown in FIG. 4(a), the protective cap (300) is formed in a cylindrical shape. The protective cap (300) is a cylindrical shape having a predetermined diameter, and includes a first cap (310) formed with the front and rear ends open, and a second cap (320) formed protruding a predetermined length from a portion of the front of the first cap (310). That is, the first cap (310) and the second cap (320) are formed integrally, but with a step formed therein.

[0059] As shown in FIG. 4(b), the inner diameter of the first cap (310) is formed to be the same as the diameter of the insertion tube (120), so that the first cap (310) is coupled to the end of the insertion tube (120), and a sponge (210) is inserted inside the second cap (320). As the sponge (210) is inserted into the second cap (320), the sponge (210) may not obstruct the view of the camera (140). This will be described in more detail later with reference to FIG. 5.

[0060]

[0061] FIG. 5 illustrates a side view and a front view of a fistula treatment system according to a first modified example of an embodiment of the present invention. As shown in FIG. 5 (a), the protective cap (300) is formed to include a second cap (320) that protrudes forward by a predetermined length from a portion of the front of the first cap (310), and the horizontal center axis of the second cap is formed differently from the horizontal center axis of the first cap (310) so that only the sponge (210) of the fistula treatment device (200) is inserted into the second cap (320).

[0062] That is, as shown in FIG. 5(b), the front cross-section of the first cap (310) and the front cross-section of the second cap (320) are formed to overlap only in a partial area. A sponge (210) is inserted inside the second cap (320), and a camera (140) and a light (150) provided at the end of the insertion tube (120) are positioned in the area where the front cross-section of the first cap (310) and the front cross-section of the second cap (320) do not overlap, so that the sponge (210) is not photographed in the area where the camera (140) photographs, thereby securing a field of view.

[0063]

[0064] FIG. 6 illustrates a side view of a fistula treatment system according to a second modified example of an embodiment of the present invention. As shown in FIG. 6, the protective cap (400) of the fistula treatment system according to the second modified example is formed such that the second cap (420) protrudes from the front of the first cap (410), and a hinge portion (430) is formed between the second cap (420) and the first coupling (410) so that the angle can be adjusted.

[0065] This is to allow the sponge (210) to be inserted in correspondence with the location where the fistula is formed. If the fistula is formed in a shape that is nearly vertical, the insertion tube (120) can be inserted into the body without adjusting the angle of the second cap (420) as shown in FIG. 6 (a), thereby allowing the sponge (210) to be inserted into the fistula.

[0066] On the other hand, if the hole is formed in a shape that is nearly horizontal, as shown in Fig. 6 (b), the second cap (420) can be rotated at a predetermined angle and then a sponge (210) can be inserted into the hole.

[0067] Although the position of the insertion tube (120) can be controlled by operating the control unit (110), there are limitations to controlling only the position of the insertion tube (120) when a fistula occurs in a very narrow organ such as the esophagus. However, according to the second modified example, the present invention allows for easy insertion by controlling the angle of the second cap (420) even if the location where the fistula is formed is a location where it is difficult to insert the sponge (210) by means of the protective cap (400).

[0068]

[0069] In the protective cap (300, 400) according to the first and second variations, since a part of the sponge (210) is exposed to the outside, the sponge (210) may be contaminated or damaged, and while the insertion tube (120) is inserted into the body and moves to the fistula, the sponge (210) may cause injury to the inner wall of the user's organ. To prevent this, the protective cap (500) may be formed in a shape in which the second cap (520) into which the sponge (210) is inserted can be opened and closed.

[0070]

[0071] FIG. 7 illustrates a side view of a fistula treatment system according to a third variation of an embodiment of the present invention. The protective cap (500) of the fistula treatment system according to the third variation includes a first cap (510) coupled to an insertion tube (120) as shown in FIG. 7 and a second cap (520) into which a sponge (210) is inserted.

[0072] The second cap (520) is formed to include an opening / closing part (521) and a protective part (522) that are joined facing each other, wherein the opening / closing part (521) is formed with an interior that is concave downward and the protective part (522) is formed with an upward convex shape. The sponge (210) is stored in the space formed by the joining of the opening / closing part (521) and the protective part (522).

[0073] A hinge portion (530) is formed between the opening / closing portion (521) of the first cap (510) and the second cap (520) to allow for angle adjustment of the opening / closing portion (521), and one end of a wire (540) formed by extending along the length direction of the insertion tube (120) is connected to the opening / closing portion (521), and an operating lever (560) is connected to the other end of the wire (540). At this time, the operating lever (560) is located externally because it must be operated by a medical professional.

[0074] A hinge portion (530) is formed between the first cap (510) and the second cap (520) so that the second cap (520) can be angle-adjusted, and when the second cap (520) rotates counterclockwise according to FIG. 7, the sponge (210) is exposed to the outside and can be inserted into the hole.

[0075] FIG. 7(a) illustrates the case where the second cap (520) is closed, and the second cap (520) is inserted into the body in a closed state. At this time, a fixing band (550) is formed along the length of the insertion tube (120) to organize the wire (540) so that the wire (540) and the insertion tube (120) do not get tangled.

[0076] When the location of the internal fistula is reached, as shown in FIG. 7 (b), when a medical professional operates the operating lever (560), the opening / closing part (521) of the second cap (520) rotates counterclockwise, exposing the sponge (210), and the exposed sponge is inserted into the fistula.

[0077] At this time, it is preferable that the protective part (521) of the second cap (520) be formed of a transparent material so as not to obstruct the view of the camera (140).

[0078]

[0079] The technical concept of the present invention should not be interpreted as being limited to the above-described embodiments. Not only is the scope of application diverse, but various modifications are possible at the level of a person skilled in the art without departing from the essence of the invention claimed in the claims. Accordingly, such improvements and modifications fall within the scope of protection of the present invention insofar as they are obvious to a person skilled in the art.
