Description

Technical Field

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

Background Art

[0002] A drainage tube is inserted into the human body for discharging body fluids after surgery and observing bleeding, by inserting a drainage tube into the surgical site to observe the discharge of secretions from the wound, secretions accumulated in the body, and secretions and bleeding after surgery and treatment.

[0003] At this time, the drainage tube is fixed at the position desired by the surgeon. However, the drainage tube often deviates from the fixed position within a few days after surgery due to the movement (peristaltic movement) of the intestinal tract that occupies most of the abdominal cavity space. As a result, it becomes impossible to discharge unnecessary body fluids, blood, or secretions, which are the original purpose of the drainage tube, and the function is substantially lost. As a method currently being carried out to solve this problem, there is a method of fixing the drainage tube to the peritoneum in the abdominal cavity using sutures, but there is no significant difference in the results with this method either.

[0004] Recently, for the easy and effective fixation of the drainage tube, a method has been attempted to move and fix the drainage tube to the desired position through an extraperitoneal route outside the abdominal cavity, that is, outside the peritoneum, and it has been confirmed that it has an improved effect compared to the conventional method in which the drainage tube is directly inserted into the abdominal cavity.

[0005] The abdominal cavity is composed of the abdominal wall. The abdominal wall is large and consists of skin, subcutaneous fat layer, muscle layer surrounded by fascia in the front and back, fascia, preperitoneal fat layer, and peritoneum. Since the drainage tube itself is made of a soft material, auxiliary instruments are required to move the drainage tube to the desired position through an extraperitoneal route. Insertion of an auxiliary instrument that creates a tunnel parallel to the curved surface of the abdominal cavity along the abdominal wall needs to be done so as not to damage the tissues and organs. Among the layers that make up the abdominal wall, the layer that is least damaged and can be easily moved is the preperitoneal fat tissue plane. If the auxiliary instrument is straight while the abdominal cavity surface is curved, there is a high possibility of damage to blood vessels and structures when penetrating between the curved tissues.

[0006] The preperitoneal fat tissue plane is a physically weak tissue layer and can be easily dissected. Therefore, passing through the preperitoneal fat tissue plane among the possible extraperitoneal routes is the easiest and safest way to reach the target point.

[0007] However, insertion of such a drainage tube through the extraperitoneum is currently impossible with existing techniques, and the need for a device that can guide or assist for such a purpose has been pointed out, but among the conventional drainage tubes and their related devices, none can meet this requirement.

Summary of the Invention

Problems to be Solved by the Invention

[0008] The technical problem to be achieved by the present invention is to provide a drainage tube guiding device that can reach the target point while dissecting the extraperitoneal fat layer without damaging the tissues and organs and guide the drainage tube.

Means for Solving the Problems

[0009] According to one embodiment, a drain tube guiding device is provided. The drain tube guiding device includes an outer inserter that is drawn along the abdominal wall, and an inner inserter that is inserted into the hollow of the outer inserter and is drawn while peeling tissue in front of the outer inserter. The outer inserter includes a head portion that extends in one direction, and a guide tube that extends downward from the head portion.

[0010] The head portion may include an inlet that communicates with the hollow of the guide tube so that the inner inserter or the drain tube is inserted into the guide tube on the upper surface.

[0011] The inner inserter may include a fastening portion coupled to the head portion, and a penetrating portion inserted into the hollow of the outer inserter.

[0012] A protruding portion that penetrates the guide tube and protrudes forward may be formed in the penetrating portion.

[0013] The protruding portion may be formed to incline downward in the terminal direction.

[0014] The head portion may have fastening grooves formed on both sides of the inlet, and the fastening portion may include fitting portions that protrude on both sides and are fitted into the fastening grooves.

[0015] The length of the guide tube may be characterized in that it is 21 cm or more and 31 cm or less.

[0016] The guide tube may be characterized by having a curved shape.

Advantages of the Invention

[0017] It is possible to reach the target point while peeling the extraperitoneal fat layer without damaging tissues and organs, and guide the drain tube.

[0018] Since it is possible to insert and operate the drain tube through the extraperitoneal route, the drain tube will not be displaced due to the movement of the intestine or the body movement after the operation, and the drainage treatment can be performed until the desired period.

[0026] Referring to FIGS. 1 to 5, a drainage tube guiding device according to an embodiment includes an outer inserter 100 and an inner inserter 200.

[0027] The abdominal cavity is formed by the abdominal wall. The abdominal wall is composed of skin, subcutaneous fat layer, muscular layer fascia surrounded by fascia on the front and back, preperitoneal fat layer, and peritoneum.

[0028] As an embodiment, the outer inserter 100 may be drawn along the abdominal wall parallel to the curved surface of the abdominal cavity.

[0029] As an embodiment, the inner inserter 200 may be inserted into the hollow of the outer inserter 100 and drawn while peeling the tissue in front of the outer inserter 100. When reaching the target point, the inner inserter 200 is separated from the outer inserter 100, and a drainage tube can be inserted through the insertion port 111 of the outer inserter 100.

[0030] As an embodiment, the outer inserter 100 may include a head portion 110 and a guide tube 120.

[0031] In one embodiment, the head portion 110 may be formed in a bar shape extending in both directions and may include an inlet 111 into which the inner inserter 200 or the drain pipe is drawn on the upper surface.

[0032] In one embodiment, the inlet 111 may be formed to communicate with the hollow of the guide tube 120.

[0033] In one embodiment, the head portion 110 is deformable into various shapes. As shown in the figure, it may have a bar shape extending in both side directions or a spherical shape formed of a curved surface, or may be any of polyhedrons with six or more faces.

[0034] In one embodiment, the head portion 110 may be in the form of a rod or bar extending in both side directions so as to serve as a handle, and may further include a plurality of grip grooves (not shown) facing inward and spaced apart from each other for the user's grip.

[0035] The grip grooves (not shown) may be formed as a plurality of grooves recessed to fit the shape of the fingers for a comfortable grip feeling when the user holds the head portion 110 in the hand.

[0036] In one embodiment, fastening grooves 112 may be formed on both sides of the inlet 111 of the head portion 110.

[0037] In one embodiment, the guide tube 120 may be formed in a hollow shape communicating with the inlet 111, and may guide the inner inserter 200 or the drain pipe drawn through the inlet 111.

[0038] In one embodiment, the guide tube 120 extends downward on the lower surface of the head portion 110, but may be formed to extend in a spiral direction so as to form a curved surface as shown in the figure.

[0039] The longitudinal axis of the abdominal cavity is about 30 to 50 cm, the transverse axis is about 20 to 30 cm, and the cross-sectional radius of the abdominal cavity is about 10 to 20 cm, but may vary depending on the body type.

[0040] In one embodiment, the guide tube 120 may have a curved shape with a radius of curvature of 12 to 42 cm so as to be able to move smoothly along the abdominal cavity in consideration of the curved shape, width and depth of the abdominal cavity.

[0041] In one embodiment, the guide tube 120 may have a length of 21 to 31 cm in consideration of the width and depth of the abdominal cavity.

[0042] In one embodiment, the guide tube 120 may be formed of a plastic material or a metal material having a non-bending hardness.

[0043] In one embodiment, the guide tube 120 may be formed of a bendable soft plastic material.

[0044] In one embodiment, the inner inserter 200 may include a fastening portion 210 and a penetrating portion 220.

[0045] In one embodiment, the fastening portion 210 may be coupled to the head portion 110 of the outer inserter 100.

[0046] In one embodiment, the fastening portion 210 may be formed to protrude on both sides and include a fitting portion 211 that is fitted into the fastening groove 112 of the head portion 110.

[0047] In one embodiment, the fastening portion 210 may be formed in a bar shape extending in both directions.

[0048] In one embodiment, when the fastening portion 210 is coupled to the head portion 110, the bar shapes on both sides of the head portion 110 and the bar shapes on both sides of the fastening portion 210 may be fastened perpendicular to each other. In one embodiment, when the fastening portion 210 is coupled to the head portion 110, the bar shapes on both sides of the head portion 110 and the bar shapes on both sides of the fastening portion 210 may have a cross shape. This facilitates the user's grip.

[0049] As an embodiment, the penetration portion 220 may be inserted into the hollow of the outer inserter 100 through the inlet 111.

[0050] As an embodiment, one side of the penetration portion 220 may be coupled to the fastening portion 210, and a protruding portion 221 that penetrates the guide tube 120 and protrudes forward may be formed on the other side.

[0051] The protruding portion 221 may be formed to incline downward in the terminal direction as an embodiment. That is, the protruding portion 221 may have a round shape with a non-pointed tip.

[0052] The protruding portion 221 may be formed in a wedge shape with a non-pointed tip as an embodiment.

[0053] With the protruding portion 221 having a non-pointed tip, it is possible to reach the target point while peeling the extraperitoneal fat layer without damaging tissues and organs.

[0054] In a state where the inner inserter 200 is coupled to the outer inserter 100, the protruding portion 221 can be easily drawn into the extraperitoneal path (for example, the extraperitoneal fat layer), and damage to extraperitoneal organs and blood vessels can be prevented.

[0055] The guide tube 120 of the present invention may extend spirally so as to have a length of 21 to 31 cm and a curve radius of 12 to 42 cm. Such numerical limitations are within a range that can be changed according to differences in body types when reaching the target point farthest from the insertion portion of the abdominal drainage tube for inserting the drainage tube in general. By inserting the drainage tube outside the abdominal cavity, the movement of the drainage tube in response to the peristaltic movement of the intestine can be minimized, so that the body fluid in the abdominal cavity can be effectively drained for a long time. Therefore, the therapeutic effect can be enhanced compared to the conventional method, that is, the procedure of inserting and fixing the drainage tube into the abdominal cavity through the abdominal cavity.

[0056] The present invention relates to a drain tube guiding device including a protruding portion 221 with a non-pointed tip. By reaching the target point while peeling the extraperitoneal fat layer without damaging tissues and organs, a drain tube can be inserted through the retroperitoneum to drain body fluids in the abdominal cavity. Therefore, the process of inserting and fixing the drain tube into the abdominal cavity through the conventional surgical site can be performed more easily, and the therapeutic effect can be enhanced.

[0057] As described above, the embodiments of the present invention have been described in detail. However, the scope of the rights of the present invention is not limited thereto, and various modifications and improvements made by those skilled in the art using the basic concept of the present invention defined in the following claims also belong to the scope of the rights of the present invention.

[0058] Those having ordinary knowledge in the technical field related to this embodiment will understand that it can be realized in a modified form without departing from the essential characteristics described above. Therefore, the disclosed method should be considered from an exemplary perspective rather than a limiting perspective. The scope of the present invention is shown in the claims rather than the above description, and all differences within the equivalent scope should be construed as being included in the present invention.
