Description

Technical Field

[0001] The utility model relates to the field of medical drainage, in particular to a suture-free full-layer closed drainage device. Background Art

[0002] Drainage tubes are frequently used during chest, gastrointestinal, and urinary drainage procedures. They are used to remove blood, urine, and accumulated fluid from the patient's body, while also allowing for observation of complications such as intra-abdominal bleeding, gastrointestinal perforation, and anastomotic leaks. They are one of the most commonly used and important surgical techniques in abdominal surgery. During laparoscopic surgery, a laparoscopic trocar, also known as a puncture card, is used to create a perforation in the skin and establish pneumoperitoneum to complete the procedure. Postoperatively, the hole created by the laparoscopic trocar, also known as the puncture card hole, serves as a pathway for drainage tube placement.

[0003] In previous surgical procedures, conventional methods were usually used to fix the drainage catheter;

[0004] Suture fixation method: Suture fixation method is a traditional fixation method, which is to use surgical sutures to fix the drainage tube on the skin on both sides of the drainage tube opening.

[0005] However, the diameters of the puncture cards are different, and the sizes of the puncture card holes formed are also different, and the circumferences of the drainage tubes are also different. Since the size of the puncture card hole is not coordinated with the drainage tube, the drainage fluid often leaks out; at the same time, when the patient turns over in sleep or pulls and squeezes the drainage tube during activities, the gap between the drainage tube and the puncture card hole becomes larger, which also leads to drainage fluid leakage; since the drainage fluid contains high levels of protein and sugar, the wet dressing provides conditions for bacterial growth and thus causes postoperative infection.

[0006] At the same time, after the drainage tube is removed, for most patients, the clinical practice is to not suture, waiting for tissue proliferation to gradually fill the sinus formed by the drainage tube, so that the hole closes naturally. However, in some cases, such as patients with low albumin levels and patients with liver cirrhosis, there will be a lot of fluid exudate from the hole after the drainage tube is removed. At this time, suturing is generally performed to promote wound healing and reduce fluid exudate. During the suturing process, it is often necessary to suturing under local anesthesia, and the patient needs to endure the pain of injecting local anesthetics. If the disinfection is not thorough or there is a lack of sufficient sterile awareness during suturing, there is a great risk of infection when the drainage tube port is directly connected to the abdominal cavity and there is a lot of exudate. At the same time, in patients with obese bodies, if the suture depth is not enough, it is easy to cause incomplete suture, and even require a second suturing, which greatly increases the patient's healing time. How to invent a suture-free full-thickness closed drainage device to improve these problems has become a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0007] In order to make up for the above shortcomings, the utility model provides a suture-free full-thickness closed drainage device, which aims to improve the problem that drainage fluid outflow easily causes postoperative infection and the problem that some patients need to suture the incision.

[0008] The utility model is realized as follows: a suture-free full-thickness closed drainage device, comprising

[0009] A drainage device, comprising skin, subcutaneous tissue, and a muscle layer; a drainage tube is provided above the skin and subcutaneous tissue; and a puncture hole is provided in the skin and subcutaneous tissue directly below the drainage tube;

[0010] A drainage tube fixing device, comprising a fixed arc plate, the fixed arc plate being fitted on one side of the drainage tube, the bottom of the fixed arc plate being inserted into the opening of the stamping card;

[0011] A skin fixation device, comprising a skin fixation ring, the skin fixation ring being fixedly attached to the skin and subcutaneous tissue, the skin fixation ring being located outside the fixed arc plate;

[0012] The suturing mechanism includes a first suture and a second suture. The first suture passes through the skin, subcutaneous tissue and muscle layer and is connected to the fixed arc plate and the skin fixing ring in a limiting manner.

[0013] In a preferred technical solution of the present invention, the skin fixing ring is arranged in an arc shape, and the outer edge and the inner edge of the upper surface of the skin fixing ring are both arranged in an arc shape.

[0014] In a preferred technical solution of the present invention, both ends of the skin fixing ring are fixedly connected with fixing ring holes, and the fixing arc plate is located between the two skin fixing rings.

[0015] In a preferred technical solution of the present invention, a switch is provided on one side of the fixing ring hole, and the switch is a vertical Z-shaped gap. The gap is located on the outside of the fixing ring hole, and the distance of the gap is the same as the diameter of the first suture line.

[0016] In a preferred technical solution of the present invention, the fixed arc plate is in the shape of a half hollow cone, the bottom of the fixed arc plate is an inwardly inclined surface, and the inclination angle of the inclined surface of the fixed arc plate cone is 15° to the vertical drainage tube hole.

[0017] In a preferred technical solution of the present invention, a winding guide rail is provided in the middle of the arc-shaped surface of the fixed arc plate, and drainage pipe fixing rings are fixedly connected to both ends of the top of the fixed arc plate.

[0018] In a preferred technical solution of the present invention, a vertical Z-shaped gap is also provided on the outer side of the drainage tube fixing ring, and the distance of the gap is the same as the diameter of the first suture line.

[0019] In a preferred technical solution of the present invention, the first suture thread passes through the skin fixing ring on one side and is inserted into the skin and subcutaneous tissue about 3 cm away from the puncture hole in the vertical direction of the skin fixing ring, and the needle is removed from the muscle layer. One side of the first suture thread is passed through the drainage tube fixing ring, the winding guide rail and the drainage tube fixing ring on the other side, and then the needle is inserted through the muscle layer on the other side, and the needle is removed from the skin and subcutaneous tissue on the other side about 3 cm away from the puncture hole. After the needle is removed, it passes through the fixing ring hole on the same side.

[0020] In a preferred technical solution of the present invention, the suturing mechanism also includes a second suture thread, which is wrapped around the drainage tube fixing ring at 1 cm and tied to fix it. The two ends of the second suture thread are respectively passed through the fixing ring holes on both sides of the skin fixing ring and tied to knots. The second suture thread is fixedly connected to the drainage tube in conjunction with the skin fixing ring.

[0021] The beneficial effects of the present invention are as follows: the present invention obtains a suture-free full-thickness closed drainage device through the above-mentioned design. When a patient using the drainage tube device needs to suture the drainage tube opening after surgery, the drainage tube opening can be directly closed in full thickness. At the same time, thanks to the presence of the wedge-shaped side, the patient using the drainage device can reduce drainage fluid leakage during the drainage tube drainage process. Since the drainage tube suture is connected to the drainage tube fixing ring, the drainage tube fixing ring is connected to the skin fixing ring, and the skin suture is fixed to the skin fixing ring, the layer-by-layer transmission reduces the displacement of the drainage tube caused by pulling, which can reduce the patient's postoperative pain. Due to the reduction of exudate, the drainage tube closure surgery is not required, thereby greatly reducing the risk of infection. Since the suture passes through the peritoneal layer and the muscle sheath layer in advance, the situation of incomplete suture in patients who need drainage tube opening closure surgery is avoided.

[0032] The drainage device 100 includes skin and subcutaneous tissue 120 and a muscle layer 130. A drainage tube 110 is provided above the skin and subcutaneous tissue 120. A puncture hole is provided in the skin and subcutaneous tissue 120 directly below the drainage tube 110.

[0033] The drainage tube fixing device 200 includes a fixed arc plate 210. The fixed arc plate 210 is attached to one side of the drainage tube 110, and the bottom of the fixed arc plate 210 is inserted into the opening of the stamp;

[0035] The suturing mechanism 400 includes a first suture 410 and a second suture 420 . The first suture 410 penetrates the skin and subcutaneous tissue 120 and the muscle layer 130 and is connected to the fixed arc plate 210 and the skin fixing ring 310 in a limiting manner.

[0036] See also Figure 2 and Figure 3 The skin fixation ring 310 is arc-shaped, with both the outer and inner edges of its upper surface being arc-shaped. A fixing ring hole 320 is fixedly connected to each end of the skin fixation ring 310, with the fixing arc plate 210 positioned between the two skin fixation rings 310. A switch is provided on either side of the fixing ring hole 320. The switch is a vertical Z-shaped gap located outside the fixing ring hole 320, and the gap distance is the same as the diameter of the first suture 410.

[0037] The fixed arc plate 210 is shaped like a half-hollow truncated cone. The bottom of the fixed arc plate 210 is an inwardly inclined surface, with the angle of the cone-shaped surface of the fixed arc plate 210 being set at 15 degrees to the vertical drainage tube 110 hole. The fixed arc plate 210's wedge-shaped side is embedded in the skin to effectively prevent leakage of drainage fluid.

[0045] See also Figure 2 and Figure 3 The skin fixation ring 310 is arc-shaped, with both the outer and inner edges of its upper surface being arc-shaped. A fixing ring hole 320 is fixedly connected to each end of the skin fixation ring 310, with the fixing arc plate 210 positioned between the two skin fixation rings 310. A switch is provided on either side of the fixing ring hole 320. The switch is a vertical Z-shaped gap located outside the fixing ring hole 320, and the gap distance is the same as the diameter of the first suture 410.

[0046] The fixed arc plate 210 is shaped like a half-hollow truncated cone. The bottom of the fixed arc plate 210 is an inwardly inclined surface, with the angle of the cone-shaped surface of the fixed arc plate 210 being set at 15 degrees to the vertical drainage tube 110 hole. The fixed arc plate 210's wedge-shaped side is embedded in the skin to effectively prevent leakage of drainage fluid. The fixed arc plate 210 is used to block the gap between the puncture hole and the drainage tube 110. A winding guide rail 230 is provided in the middle of the curved surface of the fixed arc plate 210, and the drainage tube fixing rings 220 are fixedly connected to the top and ends of the fixed arc plate 210.

[0047] See also Figure 3 and Figure 4A vertical Z-shaped gap is also provided on the outside of the drainage tube fixing ring 220 , and the distance of the gap is the same as the diameter of the first suture line 410 . The first suture 410 passes through the skin fixing ring 310 on one side and is inserted into the skin and subcutaneous tissue 120 about 3 cm away from the puncture hole in the vertical direction of the skin fixing ring 310, and the needle is removed from the muscle layer 130. One side of the first suture 410 passes through the drainage tube fixing ring 220, the winding guide 230 and the drainage tube fixing ring 220 on the same side, and then enters the needle through the muscle layer 130 on the other side, and the needle is removed from the skin and subcutaneous tissue 120 on the other side about 3 cm away from the puncture hole. After the needle is removed, it passes through the fixing ring hole 320 on the same side. Since the skin fixing ring 310 and the skin and subcutaneous tissue 120, and the fixing arc plate 210 and the drainage tube 110 are respectively fixedly connected through the first suture 410, the stability of the drainage tube 110 is ensured, while reducing the displacement of the drainage tube 110 caused by pulling or squeezing. In addition, due to the dispersion of force, the pain of the patient pulling the drainage tube 110 is reduced.

[0048] See also Figure 4 and Figure 5 The suturing mechanism 400 also includes a second suture 420. The second suture 420 is wrapped around the drainage tube fixing ring 220 at 1 cm and tied to fix it. The two ends of the second suture 420 are respectively passed through the fixing ring holes 320 on both sides of the skin fixing ring 310 and tied to a knot. The second suture 420 is fixedly connected to the drainage tube 110 in conjunction with the skin fixing ring 310. No local anesthesia is required, and the drainage tube opening can be directly closed in its entirety, reducing the risk of infection caused by drainage tube 110 exudation or drainage tube closure surgery, and avoiding the situation where incomplete suturing is required in patients who need drainage tube opening closure surgery.

[0049] Working principle:

[0050] Drainage tube fixation:

[0051] After the abdominal surgery is completed, the drainage tube 110 is placed through the puncture hole. First, the fixed arc plate 210 is assembled with the drainage tube 110. The drainage end of the drainage tube 110 can be placed into the abdominal cavity through the puncture hole. The end of the drainage tube 110 connected to the drainage bag and the fixed arc plate 210 remain outside the abdominal cavity.

[0052] Suture and fix: Use the first suture 410 to pass through the skin fixing ring 310 on one side and insert the needle into the skin and subcutaneous tissue 120 about 3 cm away from the puncture hole in the vertical direction of the skin fixing ring 310, and exit the needle through the muscle layer 130 (peritoneum). Pass the first suture 410 through the drainage tube fixing ring 220, the winding guide 230 and the drainage tube fixing ring 220 on the same side, and then insert the needle through the peritoneum on the other side, and exit the needle from the skin and subcutaneous tissue 120 on the other side about 3 cm away from the puncture hole. After exiting the needle, pass it through the fixing ring hole 320 on the same side. In this way, the skin fixing ring 310 can be tightly fixed to the skin through the first suture 410. At the same time, because the skin fixing ring 310 is buckled on the drainage tube fixing ring 220, the drainage tube fixing ring 220 is also fixed to the skin surface.

[0053] Secure the drainage tube: Wrap a second suture 420 around the appropriate location on the drainage tube 110, typically 1 cm above the drainage tube fixing ring 220, and tie a knot to secure it. Pass the two ends of the second suture 420 through the fixing ring holes 320 on either side of the skin fixing ring 310 and tie a knot. This secures the drainage tube 110 and skin fixing ring 310 together via the second suture 420. Since the skin fixing ring 310 is already firmly fixed to the skin, the drainage tube 110 is securely fixed to the skin.

[0054] Suture-free: After routine dressing changes and disinfection, use sterile scissors or a blade to cut and discard the second suture 420 directly connected to the drainage tube 110. Simultaneously, cut the two knots connecting the ends of the first suture 410 to the fixing ring holes 320, leaving the first suture 410 in place in the skin. Remove the skin fixing ring 310, the drainage tube fixing ring 220, and the drainage tube 110. Finally, use forceps to grasp the two ends of the first suture 410 and tie a knot with a mechanical device. This completes the needle-free suture drainage tube orifice closure procedure.

Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
