Abstract
Description
Technical Field
[0001] This utility model relates to the field of drainage tube fixation technology, and in particular to a drainage tube holding device for surgical drainage of the liver, gallbladder, pancreas and spleen. Background Technology
[0002] Hepatobiliary and pancreatic surgery is an important branch of surgery, focusing on the diagnosis, treatment, and prevention of surgical diseases of four important abdominal organs: the liver, gallbladder, pancreas, and spleen. Drainage tubes are a commonly used medical device in hepatobiliary and pancreatic surgery, mainly used to drain postoperative oozing blood, effusion, bile, pancreatic juice, and other fluids. To prevent accidental dislodgement, the drainage tube needs to be secured during use.
[0003] Currently, drainage tubes are mainly fixed using medical adhesive strips. During use, the drainage tube is directly attached to the patient's body using the adhesive strips. However, since the surface of the drainage tube is usually quite smooth, this method of fixation has limited effectiveness. The drainage tube can still be pulled, and if the fixation position needs to be adjusted later, the adhesive strips must be torn off first. Tearing off the adhesive strips will pull on the patient's skin and may cause discomfort. Therefore, a drainage tube fixation device for hepatobiliary, pancreatic and splenic surgical drainage is proposed. Utility Model Content

[0027] Reference Figures 1-5 This is an embodiment of the present invention, which provides a drainage tube holding device for surgical drainage of the liver, gallbladder, pancreas and spleen, which includes a shell 1. Both sides of the shell 1 are provided with tube openings for the drainage tube to pass through, and a medical strip 2 is fixedly connected to the top of the shell 1.
[0028] A sliding block 3 is slidably disposed inside the housing 1. One side of the sliding block 3 is provided with a wave-shaped undulation. A first curved groove 3a is opened along the wave line on the undulation side. A second curved groove 1a is opened inside the housing 1 to complement the first curved groove 3a. The first curved groove 3a, the second curved groove 1a and the two sets of pipe openings of the housing 1 can together form a wave-shaped tubular channel through which the drainage pipe passes.
[0029] The sliding block 3 is rotatably connected to a threaded rod 4 on the side opposite to the first curved groove 3a. The threaded rod 4 is used to adjust the sliding block 3 to slide within the housing 1 so that the sliding block 3 is misaligned with the two sets of tube openings. The threaded rod 4 is threaded through the housing 1. Before installing the drainage tube, the device is first inserted into the drainage tube. During insertion, the threaded rod 4 is rotated. When the threaded rod 4 rotates, it drives the sliding block 3 to slide within the housing 1, so that the sliding block 3 is misaligned with the two tube openings of the housing 1. At this time, the drainage tube can be passed through the two tube openings of the housing 1. When fixing the drainage tube, the device is first pasted in the appropriate position using the medical strip 2. The threaded rod 4 is rotated so that the first curved groove 3a is close to the second curved groove 1a. Finally, the first curved groove 3a and the second curved groove 1a together squeeze the drainage tube into the shape of the block 5. Since the drainage tube is difficult to change its shape smoothly to pass through the bend when it is pulled, it is easy to get stuck in the bend and hinder the pulling process. Therefore, the drainage tube can be prevented from being pulled.
[0030] like Figures 2-4 As shown, at least one set of movable cavities is provided in the sliding block 3. Each set of movable cavities is slidably connected with a stop block 5. The end of the stop block 5 passes through the movable cavity and extends into the first curved groove 3a. A spring 6 is abutted between the side of the stop block 5 facing away from the first curved groove 3a and the inner wall of the movable cavity. The stop block 5 is used to create a groove on the drainage tube, thereby further preventing the drainage tube from being pulled. The spring 6 makes the stop block 5 elastic, which can prevent the stop block 5 from excessively squeezing the drainage tube and causing the liquid flow to be obstructed.
[0031] like Figure 3 and Figure 4 As shown, the inner edges of both openings of the housing 1 are chamfered. The chamfer is to allow the drainage tube to pass smoothly through the housing 1.
[0032] like Figures 2-5 As shown, a sliding cavity matching the size of the sliding block 3 is provided inside the housing 1, and the sliding block 3 is slidably disposed inside the housing 1 through the sliding cavity.
[0033] like Figures 1-5 As shown, a button 7 is fixedly connected to one end of the threaded rod 4 outside the housing 1. The button 7 has a knurled pattern on its outer side. The button 7 is used to facilitate the rotation of the threaded rod 4 and to prevent slippage when rotating the button 7.
[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
