Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an anti-bend, easy-to-fix, and cuttable abdominal cross drainage catheter. Background Technology

[0002] With the rapid development of medical technology, surgical procedures are becoming increasingly widespread. During surgery, pus, blood, lymph, and tissue exudate can accumulate in the body's tissues or cavities. If these fluids are not drained in time, they can lead to infection, affect wound healing, and even cause more serious complications. Therefore, an effective instrument is needed to achieve drainage, and drainage tubes have emerged and are widely used. For example, in debridement and other types of surgery, drainage tubes have become important medical devices for preventing postoperative infection and promoting wound healing.

[0003] However, existing drainage tubes have the following drawbacks: 1) Drainage tubes on the body surface are prone to bending due to changes in patient position or skin fixation, causing drainage interruption; 2) Drainage tubes placed inside the body lack intuitive cutting marks; 3) Existing drainage tubes are fixed to the skin by wrapping the wire around the outer wall of the drainage tube and tying a knot. If the coil fixing the drainage tube is too loose, the drainage tube is easy to fall out. If the coil fixing the drainage tube is too tight, it is easy to compress the inner diameter of the drainage tube, affecting drainage efficiency. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a bend-resistant, easy-to-fix, and cuttable abdominal cross drainage catheter, comprising: A cross-groove drainage tube inserted into the body; A cylindrical drainage tube is placed outside the body. One end of the cylindrical drainage tube is fixedly connected to the cross-grooved drainage tube, and the other end is detachably connected to a negative pressure drainage ball or drainage bag. The tube wall at the end of the cylindrical drainage tube connected to the cross-grooved drainage tube is provided with a receiving cavity. An anti-bending component is disposed within the receiving cavity; A fixing auxiliary component is symmetrically disposed on the side wall of the circular tube-shaped drainage tube. The fixing auxiliary component is located on the side of the circular tube-shaped drainage tube close to the cross-grooved drainage tube, and the fixing auxiliary component is provided with a first origin near the cross-grooved drainage tube.

[0005] Furthermore, a retention length scale line is made on the outer wall of the circular tube drainage tube, starting from the first origin and extending to the end of the cross-groove drainage tube that is not connected to the circular tube drainage tube.

[0006] Furthermore, the length of the cross-groove type drainage tube is 45cm.

[0007] Furthermore, the accommodating cavity is a cylindrical hollow sandwich structure disposed in the wall of the circular tube-shaped drainage tube, and the accommodating cavity is coaxially arranged with the inner cavity of the circular tube-shaped drainage tube.

[0008] Furthermore, the length of the accommodating cavity is 3 cm.

[0009] Furthermore, the anti-bending component is a continuous steel wire spring, which is coiled within the accommodating cavity.

[0010] Furthermore, the spring spacing of the wire spring is no greater than 3mm.

[0011] Furthermore, the fixing auxiliary component is arc-shaped, and the fixing auxiliary component and the circular tube drainage tube are integrated into a single structure design. The hollow area between the fixing auxiliary component and the circular tube drainage tube is a fixing guide area.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The present invention provides an anti-bending, easy-to-fix, and cutable abdominal cross-shaped drainage catheter with a receiving cavity in the drainage tube area at the body surface. The receiving cavity is equipped with an anti-bending component, which can effectively prevent the drainage tube at the body surface from being bent and can effectively maintain the smooth drainage of the lumen.

[0013] 2. The present invention relates to an anti-bend, easy-to-fix, and cuttable abdominal cross-shaped drainage tube. The cross-shaped drainage tube, which is placed in the body, is provided with retention scale lines to assist doctors in accurately positioning the cutting length and improving cutting accuracy.

[0014] 3. The present invention provides a bend-resistant, easy-to-fix, and cutable abdominal cross drainage tube with a fixing auxiliary component on the wall of the drainage tube at the body surface. After the suture passes through the fixing guide area, it is wrapped around the fixing auxiliary component to fix the drainage tube, which can prevent the drainage tube from slipping off without reducing the inner diameter of the drainage tube.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model.

[0018] To keep the drawings concise, only the parts relevant to the invention are shown schematically in each figure, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of components with the same structure or function is shown schematically, or only one is labeled. In this document, "one" can mean not only "only one" but also "more than one".

[0019] First Embodiment Please see Figure 1-3 The technical solution for a bend-resistant, easily fixed, and cuttable abdominal cross-shaped drainage catheter provided in this embodiment includes the following: A cross-groove drainage tube 1 placed inside the body; A cylindrical drainage tube 2 is disposed outside the body. One end of the cylindrical drainage tube 2 is fixedly connected to the cross-grooved drainage tube 1, and the other end is detachably connected to a negative pressure drainage ball or drainage bag 3. A receiving cavity 21 is provided in the tube wall of the end of the cylindrical drainage tube 2 connected to the cross-grooved drainage tube 1. The bending-resistant component 4 is disposed in the receiving cavity 21; A fixing auxiliary component 5 is symmetrically disposed on the outer wall of the circular tube-shaped drainage tube 2. The fixing auxiliary component 5 is located on the side of the circular tube-shaped drainage tube 2 near the cross-groove type drainage tube 1. The fixing auxiliary component is provided with a first origin near the cross-groove type drainage tube.

[0020] The fixing auxiliary component 5 is arc-shaped, and the fixing auxiliary component 5 and the circular tube drainage tube 2 are integrated into a single structure. The hollow area between the fixing auxiliary component 5 and the circular tube drainage tube 2 is the fixing guide area 6.

[0021] As attached Figure 1 As shown, the "small ear"-like component near the lower part of the accommodating cavity 21 is the fixing auxiliary component 5. The material of the fixing auxiliary component 5 is the same as that of the round tube drainage tube 2. The shape of a single fixing auxiliary component 5 is limited to arc shape. When the drainage tube is pulled out from the body cavity for placement, the "small ear" can easily pass through the entire abdominal wall.

[0022] In specific implementation, as shown in the appendix Figure 1 As shown, from left to right, there is a cross-grooved drainage tube 1, a round tube drainage tube 2 fixedly connected to the cross-grooved drainage tube 1, and a negative pressure drainage ball or drainage bag 3 detachably connected to the round tube drainage tube 2. The cross-grooved drainage tube 1 is placed in the internal area, and the round tube drainage tube 2 is placed in the external area. The joint between the round tube drainage tube 2 and the cross-grooved drainage tube 1 is located on the body surface. This area is prone to bending due to external factors such as changes in the patient's body position. Therefore, an anti-bending device is provided for the area of ​​the round tube drainage tube 2 on the body surface. That is, a cylindrical hollow receiving cavity 21 is provided in the wall of the round tube drainage tube 2. The receiving cavity 21 is coaxially arranged with the inner cavity of the round tube drainage tube 2. An anti-bending component 4 is provided in the receiving cavity 21. Considering the actual need for anti-bending, the length of the receiving cavity 21 is set to 3cm.

[0023] Furthermore, the anti-bending component 4 is a continuous steel wire spring, which is coiled in the accommodating cavity 21. In order to further ensure that the cavity remains unobstructed when the bending angle is <90° (acute angle), the spring spacing of the steel wire spring must not be greater than 3mm.

[0024] In practice, in order to meet the needs of patients with different body types, the initial length of the cross-groove drainage tube 1 before cutting is set to 45cm. In order to assist in cutting, a retention length scale line 11 is made on the outer wall 2 of the round tube drainage tube, starting from the first origin and extending to the end of the cross-groove drainage tube 1 that is not connected to the round tube drainage tube 2.

[0025] In practice, the material of the drainage tube varies depending on the application scenario. For example, drainage tubes placed within the abdominal cavity can be made of soft materials such as silicone, latex, or polytetrafluoroethylene (PTFE). For drainage tubes placed in the extraperitoneal space or bile duct, rigid materials such as polyvinyl chloride (PVC), polyethylene (PE), or polycarbonate (PC) can be selected. The diameter of the drainage tube is also set according to the specific application scenario.

[0026] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
