Description

Technical Field

[0001] The invention relates to a drainage tube guiding device. Background Art

[0002] Drainage tubes are inserted into surgical sites to observe the drainage or bleeding of body fluids after surgery. Drainage tubes are inserted into the human body for the purpose of observing wound secretions, secretions accumulated in the body, and drainage and bleeding of surgical and postoperative secretions.

[0003] At this time, the drainage tube is fixed at the position desired by the operator. However, the drainage tube often detaches from the fixed position within a few days after the operation due to the movement (peristalsis) of the intestines that occupy most of the space in the abdominal cavity. As a result, the original purpose of the drainage tube, which is to discharge unnecessary body fluids, blood or secretions, becomes impossible, and it actually loses its function. As a current method for solving this problem, although there is a method of fixing the drainage tube to the peritoneum in the abdominal cavity using sutures, the results of this method are not much different.

[0004] Recently, in order to easily and effectively fix the drainage tube, a method of moving the drainage tube to a desired position and fixing it outside the abdominal cavity rather than inside the abdominal cavity, that is, through an extraperitoneal route, has been tried, and it has been confirmed that the effect is better than the conventional method of directly inserting the drainage tube into the abdominal cavity.

[0005] The abdominal cavity is composed of the abdominal wall. The abdominal wall is roughly composed of skin, subcutaneous fat layer, muscle layer covered by fascia in front and back, fascia, preperitoneal fat layer, and peritoneum. The drainage tube itself is made of soft material, so in order to move the drainage tube to the desired position through the extraperitoneal path, an auxiliary device is required. The insertion of the auxiliary device that forms a channel parallel to the curved surface of the abdominal wall and the abdominal cavity needs to be performed without damaging tissues and organs. Among the layers that constitute the abdominal wall, the layer that is least damaged and can be easily moved is the preperitoneal fat tissue plane. When the abdominal cavity surface is a curved surface and the auxiliary device is a straight line, it is possible to cause a lot of damage to blood vessels and structures during the period of passing through the curved tissues.

[0006] The preperitoneal fat tissue plane is a physically weaker tissue layer and can therefore be easily peeled off. Therefore, among the possible routes outside the abdominal cavity, passing through the preperitoneal fat tissue plane is the easiest and safest way to reach the target site.

[0007] However, such extraperitoneal drainage tube insertion is not achievable with current technology, and although guides or assistive devices have been proposed to achieve this goal, conventional drainage tubes and related devices do not satisfy these requirements. Summary of the invention

[0008] Technical issues

[0009] The technical problem to be solved by the present invention is to provide a drainage tube guiding device that can guide a drainage tube to a target site while peeling off the extraperitoneal fat layer without damaging tissues and organs.

[0010] Technical Solution

[0011] According to one embodiment, a drainage tube guiding device is provided. The drainage tube guiding device comprises: an outer inserter, which is introduced along the abdominal wall; and an inner inserter, which is inserted into the hollow of the outer inserter and is introduced while peeling off tissue in front of the outer inserter, wherein the outer inserter comprises: a head extending in one direction; and a guide tube extending downward from the head.

[0012] The head portion may include an introduction port that communicates with the hollow portion of the guide tube so that the inner inserter or the drainage tube can be inserted into the guide tube from above.

[0013] The inner inserter may include: a fastening portion coupled to the head portion; and a through portion inserted into the hollow of the inner inserter.

[0014] The penetration portion may be formed with a protrusion that penetrates the guide pipe and protrudes forward.

[0015] The protrusion may be formed to be inclined downward toward the distal end.

[0016] The head portion may be provided with fastening grooves on both sides of the introduction port, and the fastening portion may include a stopper portion that is formed to protrude toward both sides and is sandwiched and coupled to the fastening grooves.

[0017] The length of the guide tube may be greater than 21 cm and less than 31 cm.

[0018] The guide tube has a curved shape.

[0019] Effects of the Invention

[0020] The drainage tube can be guided to the target site while peeling off the extraperitoneal fat layer without damaging tissues and organs.

[0021] The drainage tube can be inserted and operated on via a route outside the peritoneum, and the drainage tube will not be dislocated due to intestinal movement or body movement after the operation, so drainage treatment can be performed for a desired period of time.

[0032] Reference Figures 1 to 5 According to one embodiment, a drainage tube guiding device includes an outer inserter 100 and an inner inserter 200 .

[0033] The abdominal cavity is composed of the abdominal wall, which is composed of the skin, subcutaneous fat layer, muscle layer covered by fascia in front and behind, anterior peritoneal fat layer, and peritoneum.

[0034] As an embodiment, the outer inserter 100 can be introduced along the abdominal wall parallel to the curvature of the abdominal cavity.

[0035] As an embodiment, the inner inserter 200 is inserted into the hollow of the outer inserter 100 and can be introduced while peeling off tissue in front of the outer inserter 100. When reaching the target site, the inner inserter 200 is separated from the outer inserter 100, and a drainage tube can be inserted through the introduction port 111 of the outer inserter 100.

[0036] As an embodiment, the outer inserter 100 may include a head 110 and a guide tube 120 .

[0037] As an embodiment, the head 110 may be formed in a rod shape extending in two directions, and may include an introduction port 111 on the upper surface for introducing the inner inserter 200 or the drainage tube.

[0038] As an embodiment, the introduction port 111 may be formed to communicate with the hollow portion of the guide pipe 120 .

[0039] As an embodiment, the head 110 can be deformed into various shapes. As shown in the figure, it can have a rod shape extending in both directions or a spherical shape composed of curved surfaces, or it can be any one of a polyhedron with more than six faces.

[0040] As an embodiment, the head 110 has a rod or bar shape extending in both sides so as to function as a handle. In order for the user to grip, the head 110 may further include a plurality of gripping grooves (not shown) extending inward and separated from each other.

[0041] When the user holds the head 110 in his hand, for a comfortable gripping feeling, the gripping grooves (not shown) can be formed as a plurality of grooves facing inward to correspond to the shape of fingers.

[0042] As an embodiment, the head 110 may be formed with fastening grooves 112 on both sides of the introduction port 111 .

[0043] As an embodiment, the guide tube 120 may be formed into a hollow shape communicating with the introduction port 111 , and may guide the inner inserter 200 or the drainage tube introduced through the introduction port 111 .

[0044] As an embodiment, the guide tube 120 extends downward from the lower surface of the head 110 , and as shown in the figure, can be extended in a spiral direction to form a curved surface.

[0045] The longitudinal axis of the abdominal cavity is approximately 30 to 50 cm, the transverse axis is approximately 20 to 30 cm, and the radius of the abdominal cavity cross section is approximately 10 to 20 cm, which varies depending on body size.

[0046] As an embodiment, considering the curved surface shape, width and depth of the abdominal cavity, the guide tube 120 may have a curved shape with a bending radius of 12 to 42 cm so as to be able to move smoothly along the abdominal cavity.

[0047] As an example, considering the width and depth of the abdominal cavity, the guide tube 120 may have a length of 21 to 31 cm.

[0048] As an embodiment, the guide tube 120 can be made of a plastic material or a metallic material with a hardness that cannot be bent.

[0049] As an embodiment, the guide tube 120 can be made of a flexible soft plastic material.

[0050] As an embodiment, the inner inserter 200 may include a fastening portion 210 and a through portion 220 .

[0051] As an embodiment, the fastening portion 210 can be combined with the head portion 110 of the outside inserter 100 .

[0052] As an embodiment, the fastening portion 210 may include a locking portion 211 protruding toward both sides and clamped in the fastening groove 112 of the head 110 .

[0053] As an embodiment, the fastening portion 210 may be formed in a rod shape extending in two directions.

[0054] As an embodiment, when the fastening part 210 is coupled to the head 110, the two side bar shapes of the head 110 and the two side bar shapes of the fastening part 210 can be fastened perpendicularly to each other. As an embodiment, when the fastening part 210 is coupled to the head 110, the two side bar shapes of the head 110 and the two side bar shapes of the fastening part 210 can have a cross shape. Thus, it can be easy for the user to grasp.

[0055] As an embodiment, the through portion 220 can be inserted into the hollow of the inner inserter 200 through the introduction port 111 .

[0056] As an embodiment, one side of the through portion 220 is coupled to the fastening portion 210 , and the other side may be formed with a protruding portion 221 that penetrates the guide tube 120 and protrudes forward.

[0057] As an embodiment, the protrusion 221 may be formed to be inclined downward toward the distal end. That is, the protrusion 221 may have a round shape without a sharp distal end.

[0058] As an embodiment, the protrusion 221 can be formed in a wedge shape with a blunt tip.

[0059] The projection 221 having a blunt tip makes it possible to reach the target site while peeling off the extraperitoneal fat layer without damaging tissues and organs.

[0060] When the inner inserter 200 is coupled to the outer inserter 100 , the inner inserter 200 can be easily introduced into the extraperitoneal route (for example, the extraperitoneal fat layer) through the protrusion 221 , thereby preventing damage to the extraperitoneal organs and blood vessels.

[0061] The guide tube 120 of the present invention can extend in a spiral shape with a length of 21 to 31 cm and a bending radius of 12 to 42 cm. The numerical limit as described above is a range that can vary due to differences in body shape when the target location farthest from the drainage tube insertion portion of the abdomen where the drainage tube is inserted can usually be reached. The insertion of an extraperitoneal drainage tube can minimize the movement of the drainage tube caused by intestinal peristalsis, thereby effectively draining body fluids in the abdominal cavity for a long time, and can improve the treatment effect compared to the previous method, that is, surgery in which the drainage tube is inserted through the abdominal cavity and fixed in the abdominal cavity.

[0062] The present invention relates to a drainage tube guiding device including a projection 221 with a blunt end, which does not damage tissues and organs and reaches a target location while stripping off the extraperitoneal fat layer, thereby being able to insert a drainage tube through the retroperitoneal cavity to discharge body fluids in the abdominal cavity, thereby making the previous process of inserting and fixing the drainage tube in the abdominal cavity through a surgical site easier to achieve and improving the treatment effect.

[0063] Although the embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements made by those skilled in the art using the basic concepts of the present invention defined in the claims also fall within the scope of the present invention.

[0064] It should be understood that those with ordinary knowledge in the technical field related to the present embodiment can implement it in a modified manner without departing from the essential characteristics of the above-mentioned description. Therefore, the disclosed method should be considered from the perspective of explanation rather than from the perspective of limitation. The scope of the present invention is embodied in the claims rather than the above description, and it should be interpreted that all differences within the scope of the equivalent are included in the present invention.
