Abstract
Description
Technical Field
[0001] The invention relates to a liquid discharge pipe guiding device. Background Art
[0002] The purpose of inserting a drainage tube into the human body is to observe the drainage or bleeding of body fluids after surgery. By inserting the drainage tube into the surgical site, the drainage and bleeding of wound secretions, secretions accumulated in the body, and secretions after surgery and operation can be observed.
[0003] At this time, the drainage tube is fixed in the position required by the operator. However, due to the movement (peristalsis) of the intestines, which occupy most of the space in the abdominal cavity, the drainage tube often deviates from the fixed position within a few days after the operation. In this way, the original function of the drainage tube to drain unnecessary body fluids, blood or secretions cannot be realized, and it actually loses its function. The current method to solve this problem is to suture and fix the drainage tube to the peritoneum in the abdominal cavity, but the results of this method are not much different.
[0004] In recent years, in order to conveniently and effectively fix the drainage tube, attempts have been made to move the drainage tube to the desired position for fixation through an extraperitoneal route rather than an intraperitoneal route. The results showed that this method is more effective than the previous method of inserting the drainage tube directly into the abdominal cavity.
[0005] The abdominal cavity is composed of the abdominal wall. The abdominal wall is mainly composed of skin, subcutaneous fat layer, muscle layer wrapped by fascia in front and back, fascia, preperitoneal fat layer and peritoneum. The drainage tube itself is a soft material, so auxiliary equipment is needed to move the drainage tube to the desired position through the extraperitoneal route. The layer that is least damaged and easiest to move among the abdominal wall layers is the preperitoneal fat tissue plane.
[0006] The preperitoneal fat tissue plane is a physically weak tissue layer that can be easily peeled off. Therefore, among the possible routes outside the abdominal cavity, the preperitoneal fat tissue plane is the easiest and safest way to reach the target point.
[0007] However, this method of inserting the drainage tube extraperitoneally cannot be achieved with current technology, so there is a need for a device that can guide or assist for this purpose, but the existing drainage tubes and related devices cannot meet this demand. Summary of the invention

[0039] refer to Figures 1 to 5 A drainage tube guiding device according to an embodiment includes a head portion 100 , a conduit 200 and a stripping portion 300 .
[0040] In one embodiment, the head 100 may be formed in a rod shape extending in two directions, and may include an introduction port 111 for introducing a drainage tube from a top surface.
[0041] In one embodiment, the introduction port 111 may be formed to communicate with the hollow portion of the conduit 200 .
[0042] In one embodiment, the handle portion 112 of the head 100 can be deformed into a variety of shapes. As shown in the figure, it can be a rod-shaped shape extending in both directions, a spherical shape composed of curved surfaces, or any one of a polyhedron with more than six faces.
[0043] In one embodiment, the handle portion 112 is in the shape of a rod or bar extending in both directions to serve as a handle, and may further include a plurality of gripping grooves (not shown) that are inwardly facing and spaced apart from each other to facilitate user gripping.
[0044] When the user holds the handle 112 in his hand, in order to provide a comfortable grip, a gripping groove (not shown) may be formed by a plurality of inward grooves to fit the shape of fingers.
[0045] In one embodiment, the head 100 may include an identification portion 113 protruding forward. The protruding direction of the identification portion 113 and the protruding direction of the stripping portion 300 may be consistent, so as to prevent the stripping portion 300 from being introduced in the opposite direction to the traveling direction when entering the abdominal cavity.
[0046] In one embodiment, the head 100 may be welded to one end 1 of the catheter 200 .
[0047] The abdominal cavity is composed of the abdominal wall, which is composed of the skin, subcutaneous fat layer, muscle layer wrapped by fascia in front and behind, preperitoneal fat layer and peritoneum.
[0048] In one embodiment, catheter 200 may be introduced along the abdominal wall.
[0049] In one embodiment, the conduit 200 may be formed in a hollow shape communicating with the introduction port 111 , and may guide the drainage tube introduced through the introduction port 111 .
[0050] In one embodiment, the conduit 200 may extend downwardly below the head 100 .
[0051] In one embodiment, the conduit 200 may extend downward, as shown in a straight line.
[0052] The longitudinal axis of the abdominal cavity is approximately 30cm-50cm, the transverse axis is approximately 20cm-30cm, and the cross-sectional radius of the abdominal cavity is approximately 10cm-20cm, which varies according to body size.
[0053] The longest axis of the abdominal cavity is from the diaphragm above the liver to the end of the rectum (levator ani muscle), which is about 30-50 cm depending on the size of the adult body.
[0054] Considering the width and depth of the abdominal cavity of all adults, in one embodiment, the length of the catheter 200 may be 20-40 cm.
[0055] In one embodiment, the catheter 200 may be made of a plastic material or a metal material having an unbending hardness.
[0056] In one embodiment, the catheter 200 may be made of a flexible soft plastic material.
[0057] In one embodiment, the stripping portion 300 is connected to the hollow portion of the catheter 200 and can be introduced simultaneously when the tissue is stripped from the front. After reaching the target point, the drainage tube can be inserted through the introduction port 111 of the head 100.
[0058] In one embodiment, the peeling portion 300 may be welded to the other end 2 of the catheter 200 .
[0059] See also Figure 6 and Figure 7 In one embodiment, the peeling portion 300 may include a fixing portion 310 , a protruding portion 320 , a withdrawal port 330 , and an inclined portion 340 .
[0060] In one embodiment, the fixing portion 310 may be coupled to an end portion of the catheter 200 .
[0061] In one embodiment, the fixing portion 310 is hollow, and the end of the catheter 200 is inserted into the hollow portion of the fixing portion 310 and can be welded thereto.
[0062] In one embodiment, the protrusion 320 may be formed to protrude in the introduced direction.
[0063] In one embodiment, the protrusion 320 may be formed to be inclined downward toward the end, that is, the protrusion 320 may have an arc shape with a non-sharp end.
[0064] In one embodiment, the protrusion 320 may be formed in a wedge shape with a blunt end.
[0065] The projection 320 having a blunt end makes it possible to peel off the extraperitoneal fat layer and reach the target point without damaging tissues and organs.
[0066] In one embodiment, the extraction port 330 is communicated with the hollow portion of the catheter 200 , and the drainage tube inserted into the catheter 200 can be extracted through the extraction port 330 .
[0067] In one embodiment, the shape of the extraction port 330 may be any one of a circular shape and an elliptical shape. In one embodiment, the shape of the extraction port 330 may have various shapes other than a circular shape and an elliptical shape.
[0068] When the extraction port 330 is elliptical, two drainage tubes can be extracted, thereby shortening the operation time and improving the operation efficiency.
[0069] In one embodiment, the length 6 (eg, 12.5 mm) of the extraction port 330 may be longer than the width 5 (eg, 6 mm).
[0070] In one embodiment, the inclined portion 340 may be formed to extend obliquely upward from the fixing portion 310 .
[0071] In one embodiment, the inclined portion 340 may be bent from the fixing portion 310 at an angle 3 of 25-55 degrees or less.
[0072] In one embodiment, the length 4 of the inclined portion 340 may be 1-5 cm.
[0073] Although curved instruments have the advantage of being able to follow the curvature of the abdominal cavity, turning to reach the target point may cause excessive dissection of the preperitoneal fat layer, resulting in unexpected bleeding. In addition, users may not be as skilled in using curved instruments as straight instruments, so they may be difficult to use.
[0074] In contrast, in the present invention, by using the straight-line catheter 200 and the stripping portion 300 protruding in the traveling direction and tilted upward, when moving to the target point in the abdominal cavity, the stripping of the preperitoneal fat layer can be minimized and excessive stripping to cause bleeding can be prevented.
[0075] The catheter 200 of the present invention may have a length of 20-40 cm, a length of 1-5 cm of the inclined portion 340, and a shape that is bent at an angle 3 of 25 to 55 degrees or less. Such a numerical limit range may vary according to different body shapes so as to reach the farthest target point from the abdominal drainage tube insertion site where the drainage tube is usually inserted. The insertion of the extra-abdominal drainage tube can minimize the movement of the drainage tube caused by intestinal peristalsis, thereby effectively draining the body fluid in the abdominal cavity for a long time, thereby improving the treatment effect compared with the existing method of inserting and fixing the intra-abdominal drainage tube through the abdominal cavity.
[0076] The present invention relates to a drainage tube guide device, which includes a protrusion 320 with a blunt end. The protrusion 320 can peel off the extraperitoneal fat layer and reach the target point without damaging tissues and organs. The drainage tube can be inserted into the retroperitoneal cavity to drain the body fluid in the abdominal cavity, thereby making the existing process of inserting and fixing the drainage tube into the abdominal cavity through the surgical site easier to achieve, thereby improving the treatment effect.
