Description

[Technical Field]

[0001] The present invention relates to a drainage tube guide device, and more particularly to an integrated drainage tube guide device in which a drainage tube is integrally coupled to a guide tube. [Background technology]

[0002] Drainage tubes are inserted into the body to observe the discharge of bodily fluids and bleeding after surgery by inserting them into the surgical site to observe secretions from wounds, secretions accumulated in the body, and the discharge of secretions and bleeding after surgery or treatment.

[0003] At this time, the drain is fixed in the position desired by the surgeon. However, due to the movement (peristalsis) of the intestines, which occupy most of the space in the abdominal cavity, the drain often becomes dislodged from its fixed position within a few days after surgery. This makes it impossible for the drain to fulfill its original purpose of draining unnecessary fluids, blood, or secretions, and it essentially loses its function. To solve this problem, a current method is to fix the drain to the peritoneum inside the abdominal cavity with sutures, but this method does not significantly improve the results.

[0004] Recently, in order to easily and effectively fix the drainage tube, a method has been attempted in which the drainage tube is moved to the desired location outside the abdominal cavity, i.e., via an extraperitoneal route, rather than inside the abdominal cavity, and then fixed there. This method has been found to be more effective than the conventional method in which the drainage tube was directly inserted into the abdominal cavity.

[0005] The abdominal cavity is made up of the abdominal wall. The abdominal wall is large and consists of the skin, subcutaneous fat layer, muscle layer surrounded by fascia on the front and back, fascia, preperitoneal fat layer, and peritoneum. The drainage tube itself is made of a soft material, so an auxiliary device is required to move the drainage tube to the desired location via an extraperitoneal route. Of the abdominal wall layers, the one that is least damaged and most easily moved 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, passing through the preperitoneal fat tissue plane is the easiest and safest way to reach the target site.

[0007] However, inserting such a drainage tube outside the peritoneum is not possible with current technology, and a need has been identified for a device that can guide or assist for this purpose, but none of the conventional drainage tubes and related devices exist that can meet this need. Summary of the Invention [Problem to be solved by the invention]

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

[0009] According to one embodiment, a drain guide device is provided.

[0010] The drainage tube guide device includes a head portion extending in one direction, a hollow guide tube extending downward from the head portion, and a drainage tube fixed to the end of the guide tube and pulled in while dissecting tissue in front of it.

[0011] The head portion may include an inlet on its upper surface that communicates with the hollow of the guide tube so that the drain tube can be inserted into or discharged from the guide tube.

[0012] The head portion may include an identification portion that protrudes forward.

[0013] The head portion may be any one of a bar shape extending laterally, a spherical shape with a curved surface, and a polyhedron shape with a polygonal shape.

[0014] The guide tube may include a straight portion extending in a straight direction from the head portion, and an inclined portion extending obliquely upward from the straight portion.

[0015] The inclined portion may be curved at an angle of 25 degrees or more and 55 degrees or less from the straight portion.

[0016] The length of the inclined portion may be 1 cm or more and 5 cm or less.

[0017] The length of the guide tube may be 20 cm or more and 40 cm or less.

[0018] The drainage tube may include a hose portion inserted into the hollow of the guide tube, and a dissection portion connected to an end of the hose portion, retracted while dissecting tissue forward, and detachable from the hose portion when reaching a target point.

[0019] The peeling portion may include a fixing portion fixedly coupled to an end of the guide tube, and a protruding portion protruding in a retracting direction.

[0020] The fixing portion may include a fitting groove into which the end of the guide tube is inserted, and a fitting wing that fixes the end of the guide tube.

[0021] The protrusion may be characterized by having a rounded shape with a blunt tip. [Effects of the Invention]

[0022] The drainage tube can be guided to the target location while peeling off the extraperitoneal fat layer without damaging tissues and organs.

[0023] Since the drainage tube can be inserted and surgery can be performed via a route outside the peritoneum, the drainage tube will not become displaced due to intestinal movement or body movements after surgery, and drainage treatment can be continued for the desired period.

[0030] Fig. 1 is a perspective view of a drainage tube guide device according to one embodiment. Figs. 2 and 3 are views illustrating a head portion of a drainage tube guide device according to one embodiment. Figs. 4 and 5 are views illustrating a structure in which a drainage tube of a drainage tube guide device according to one embodiment is coupled to a guide tube 200. Figs. 6 and 7 are views illustrating a structure in which a drainage tube of a drainage tube guide device according to one embodiment is separated.

[0031] 1 to 4, a drainage tube guide device according to one embodiment includes a head portion 100, a guide tube 200, and a drainage tube 300.

[0032] In one embodiment, the head portion 100 may be formed in a bar shape extending in both directions.

[0033] In one embodiment, the head unit 100 may include an inlet 111 on the upper surface that communicates with the hollow of the guide tube 200 so that the drainage tube 300 can be inserted into or removed from the guide tube 200.

[0034] In one embodiment, the inlet 111 may be formed so as to communicate with the hollow of the guide tube 200 .

[0035] In one embodiment, the handle 112 of the head 100 can be modified into various shapes. As shown in the figure, it may have a bar shape extending in both directions, a spherical shape with curved surfaces, or a polyhedron with six or more sides.

[0036] In one embodiment, the handle portion 112 may be rod-shaped or bar-shaped extending in both directions to serve as a handle, and may further include a plurality of grip grooves (not shown) facing inward and spaced apart from one another for a user's grip.

[0037] 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 when the user holds the handle portion 112 in their hand.

[0038] In one embodiment, the head unit 100 may include a forward-protruding identification unit 113. The protruding direction of the identification unit 113 may coincide with the protruding direction of the protruding unit 322, which prevents the protruding unit 322 from being retracted in the direction opposite to the direction of advancement when retracting into the abdominal cavity.

[0039] The abdominal cavity is made up of the abdominal wall, which is made up of the skin, subcutaneous fat layer, muscle layer fascia surrounded by fascia on the front and back, preperitoneal fat layer, and peritoneum.

[0040] The guide tube 200 may, in one embodiment, be retracted along the abdominal wall.

[0041] In one embodiment, the guide tube 200 may be formed in a hollow shape that communicates with the inlet 111 and may guide the drainage tube that is drawn in through the inlet 111.

[0042] In one embodiment, the guide tube 200 may extend downward onto the underside of the head portion 100 .

[0043] The longitudinal axis of the abdominal cavity is approximately 30 to 50 cm, the horizontal axis is approximately 20 to 30 cm, and the cross-sectional radius of the abdominal cavity is approximately 10 to 20 cm, but this may vary depending on body type.

[0044] The longest axis of the abdominal cavity, from the diaphragm above the liver to the end of the rectum (levator ani muscle), is approximately 30–50 cm, depending on the body size of the adult.

[0045] Considering the width and depth of the abdominal cavity of all adults, the guide tube 200 may have a length of 20 to 40 cm in one embodiment.

[0046] In one embodiment, the guide tube 200 may be made of a plastic material or a metal material that has a rigidity that does not bend.

[0047] In one embodiment, the guide tube 200 may be made from a flexible, flexible plastic material.

[0048] In one embodiment, the guide tube 200 may include a straight portion 210 extending in a straight direction from the head portion 100, and an inclined portion 220 extending at an angle upward from the straight portion 210.

[0049] In one embodiment, the inclined portion 220 may be curved from the straight portion 210 at an angle of 25 to 55 degrees.

[0050] In one embodiment, the inclined portion 220 may have a length of 1 to 5 cm.

[0051] 4 to 7, in one embodiment, the drainage tube 300 may be fixed to the distal end of the guide tube 200 and may be retracted while dissecting tissue forward. When the target location is reached, the head unit 100 and the guide tube 200 may be separated from the drainage tube 300 by the user.

[0052] In one embodiment, the drain 300 may include a hose portion 310 and a peel-off portion.

[0053] In one embodiment, the hose portion 310 may be first inserted into the hollow of the guide tube 200, and then separated from the guide tube 200 when it reaches the target location after retracting the abdominal cavity.

[0054] In one embodiment, the dissector is connected to the distal end of the hose part 310, and is pulled in while dissecting tissue forward, and upon reaching a target location, can be detached from the hose part 310. Upon reaching a target location, the dissector can be removed by the user, leaving only the hose part 310 at the target location.

[0055] In one embodiment, the peeling portion may be arrowhead shaped.

[0056] In one embodiment, the peeling portion may include a fixing portion 321 and a protruding portion 322 .

[0057] In one embodiment, the fixed portion 321 may be fixedly coupled to the distal end of the guide tube 200 .

[0058] In one embodiment, the fixing portion 321 may include a fitting groove 321a into which the end of the guide tube 200 is inserted, and fitting wings 321b that fix the end of the guide tube 200.

[0059] In one embodiment, the protrusion 322 may be formed to protrude in the retracting direction.

[0060] In one embodiment, the protrusion 322 may be formed to slope downward toward the distal end, i.e., the protrusion 322 may have a rounded shape with a blunt tip.

[0061] In one embodiment, the protrusion 322 may be formed in a wedge shape with a blunt tip.

[0062] The blunt protrusion 322 allows the target location to be reached while peeling off the extraperitoneal fat layer without damaging tissues and organs.

[0063] In one embodiment, the end of the guide tube 200 that is coupled to the ablation section may be straight, as shown in FIG.

[0064] In one embodiment, the end of the guide tube 200 that is connected to the dissection section may be curved in the opposite direction (retracted direction) to the curved direction of the inclined section 220, as shown in FIG.

[0065] The distal end of the guide tube 200 in FIG. 5 is easier to move to the target point than the distal end of the guide tube 200 in FIG. 4, and can minimize the stripping of the preperitoneal fat layer.

[0066] Curved instruments have the advantage of being suitable for moving along the curved surfaces of the abdominal cavity, but they may dissect the preperitoneal fat layer excessively when changing direction to reach the target point, which may cause unexpected bleeding. In addition, curved instruments can be difficult to use because users are not accustomed to using them compared to straight instruments.

[0067] In contrast, in the present invention, the guide tube 200 is straight and has a protruding and upwardly inclined distal end, and the blunt protruding portion 322 minimizes the dissection of the preperitoneal fat layer when moving to the target location in the abdominal cavity, thereby preventing bleeding due to excessive dissection.

[0068] The guide tube 200 of the present invention may have a length of 20 to 40 cm, and the inclined portion 220 may have a length of 1 to 5 cm and a curved shape at an angle of 25 to 55 degrees or less. These numerical limits are generally within a range that can be changed depending on body type when allowing the insertion point of an abdominal drainage tube to reach the farthest target point. By inserting the drainage tube outside the abdominal cavity, movement of the drainage tube in response to the peristaltic movement of the viscera can be minimized, allowing body fluids in the abdominal cavity to be effectively drained for a long period of time, thereby improving the therapeutic effect compared to the conventional method, i.e., a procedure in which a drainage tube is inserted and fixed inside the abdominal cavity via the abdominal cavity.

[0069] The present invention relates to a drainage tube guide device including a protrusion 322 with a blunt tip, which can reach the target point while peeling off the extraperitoneal fat layer without damaging tissues and organs, and can insert a drainage tube through the retroperitoneal cavity to drain body fluids from the abdominal cavity. This makes it easier to insert and fix a drainage tube into the abdominal cavity through a conventional surgical site, thereby improving the therapeutic effect.

[0070] The present invention relates to a drainage tube guide device in which a drainage tube including a blunt protrusion 322 is fixed to a guide tube 200, and after reaching a target point while dissecting the extraperitoneal fat layer without damaging tissues and organs, the guide tube 200 can be removed while holding the dissected portion with another instrument, without the need to pull in a separate drainage tube. The length of the drainage tube 300 can be adjusted by cutting off the excess drainage tube, including the dissected portion, with scissors.

[0071] Once the drainage tube 300 is connected to the guide tube 200 as an integral unit and reaches the target location, the guide tube 200 can be removed, thereby shortening the surgical time and improving the surgical efficiency of the surgeon. Since the drainage tube 300 reaches the target location while connected to the guide tube 200 as an integral unit, one process can be eliminated compared to other instruments in which the guide tube is inserted first and then the drainage tube is inserted into the guide tube.

[0072] Although the embodiments of the present invention have been described in detail above, the scope of the present invention is not limited to these, and various modifications and improvements made by those skilled in the art using the basic concept of the present invention defined in the claims below also fall within the scope of the present invention.

[0073] Those skilled in the art will understand that the present invention can be realized in various modified forms without departing from the essential characteristics of the above description. Therefore, the disclosed method should be considered from an illustrative rather than a restrictive perspective. The scope of the present invention is indicated by the claims, not the above description, and all differences within the scope of the claims should be construed as being within the scope of the present invention.
