Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly to a catheter fixing device for the hepatobiliary pancreas and spleen. Background Art

[0002] The catheters in the hepatobiliary pancreas and spleen region mainly involve the catheter systems of the hepatobiliary system and the pancreas, which play a crucial role in the digestion and metabolism processes of the human body. Patients in hepatobiliary surgery are prone to having fluid accumulation in the body, and a drainage device is needed to drain the fluid to the outside of the body. The bile produced by the liver is collected into the common bile duct through the intrahepatic bile ducts such as the right hepatic duct and the left hepatic duct.

[0003] Publication No. CN118925030A discloses a catheter fixing device, a catheter fixing device for hepatobiliary and pancreatic surgery, including a movable support base. An adjustable wall-hanging assembly is movably provided at the front part of the movable support base. A pressing type limit protection assembly is installed at the upper part of the adjustable wall-hanging assembly. An extrusion cut-off mechanism is slidably provided inside the pressing type limit protection assembly. The whole adopts an assembled structure. The catheter is elastically squeezed and clamped and protected by the pressing type limit protection assembly to prevent the catheter from falling off when the patient moves or being squeezed when the patient turns over. At the same time, the adjustable wall-hanging assembly is used to place the drainage bag and can cut off the outflow of the fluid in time when the fluid reaches a certain amount, reducing the risk of infection. The installation operation is simple and convenient for medical staff to replace the drainage bag.

[0004] It can be seen that the drainage tube is generally fixed with medical adhesive tape, and the end is inserted into the patient's skin, lacking protection for the catheter. Especially when there are multiple catheters on the patient, if the positions of the catheters cannot be sorted out in an orderly manner, the catheters will interfere and bend with each other, and the connection with the container is prone to excessive bending, resulting in blockage and affecting the normal drainage function. For this reason, we propose a catheter fixing device for the hepatobiliary pancreas and spleen. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a catheter fixing device for the hepatobiliary pancreas and spleen to solve the problems existing in the above background art.

[0008] Furthermore, the guiding mechanism includes a sliding sleeve, a locking knob and a guiding frame. The sliding sleeve is slidably connected to the surface of the telescopic rod. The guiding frame is fixedly connected to one side of the sliding sleeve close to the outward expansion port. The locking knob is installed on the other side of the telescopic rod.

[0011] Furthermore, a guiding frame is fixedly connected to the top of the fixture. The guiding frame has an arc-shaped structure, and its end is located above the guiding frame.

[0012] Furthermore, elastic bands are installed on both sides of the base. The ends of the two elastic bands are fixedly connected with plug-in fasteners.

[0013] Furthermore, an outlet groove is formed in the side wall of the interlayer. The first lever passes through the outlet groove and extends outwards.

[0014] The technical effects and advantages of the present invention: 1. The present invention is provided with a fixing mechanism and a sliding sleeve, which is conducive to controlling the gathering of a number of rubber blocks, thereby clamping the liquid inlet of the container, fixing the position of the container, ensuring that the connection position between the catheter and the container will not shift, and can firmly fix the position of the end of the catheter to prevent it from falling off or shifting, avoiding the falling off and loosening caused by excessive pulling, so as not to damage the catheter or surrounding tissues, so that the patient can move freely within a safe distance after the operation. Moreover, the catheter needs to pass through the sliding sleeve.

The connection angle of the telescopic rod can be locked by tightening the knob, thereby fixing the approximate angle of the catheter. When not in use, the tightening knob can be loosened to help the overall structure fold, facilitating storage and reducing the occupied volume. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0020] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. In addition, the forms of the various structures described in the following embodiments are merely illustrative, and a fixing device for hepatobiliary and pancreatic ducts involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0021] Referring to Figures 1-9 , the present invention provides a fixing device for hepatobiliary and pancreatic ducts, including a base 1. A plurality of accommodation cavities 101 are provided on the side of the base 1. A plurality of outward expansion openings 2 corresponding to the accommodation cavities 101 are fixed on the top of the base 1. A clamp 4 is provided on the upper side of the base 1. The base 1 and the clamp 4 are connected by a telescopic rod 3. A sandwich 102 is provided between each accommodation cavity 101 and the outward expansion opening 2. A set of fixing mechanisms 6 and self-locking mechanisms 7 are provided in each sandwich 102. The fixing mechanism 6 is used to fix the end of the catheter, and a guiding mechanism is provided on the telescopic rod 3.

[0022] Each set of fixing mechanism 6 includes a disc 601, a first slider 603, a rubber block 605 and a first lever 606. The disc 601 is rotatably connected within the interlayer 102. A plurality of arc-shaped grooves 602 are formed in the upper side of the disc 601. A plurality of first sliders 603 and rubber blocks 605 are provided and correspond to each other one by one. Each first slider 603 is slidably connected within the corresponding arc-shaped groove 602. The rubber block 605 is located within the accommodating cavity 101. The first slider 603 and the rubber block 605 are fixedly connected through a second slider 604. A plurality of linear grooves 1021 are formed in the lower inner wall of the interlayer 102. Each second slider 604 of the interlayer 102 is slidably connected within the corresponding linear groove 1021. The first lever 606 is fixedly connected to the circumferential surface of the disc 601.

[0023] In this embodiment, it should be specifically noted that: after hepatobiliary surgery, in order to avoid complications such as fluid accumulation, bile leakage or bleeding in the surgical area, hepatobiliary drainage catheters are often used to guide the drainage of excess fluid in the body. The accommodating cavity 101 is used to place containers such as drainage bags or drainage bottles. The liquid is collected through the drainage bag or drainage bottle. A plurality of accommodating cavities 101 are designed, specifically 3 - 5, and multiple containers can be placed. The catheters in the hepatobiliary and pancreatic regions are not just one, but composed of multiple catheters, and they each undertake different physiological functions. Multiple containers can undertake the liquid collection functions of different regions. Multiple containers can separately collect the catheter liquids from different parts or with different functions, such as the postoperative drainage fluids of organs such as the liver, gallbladder, pancreas and spleen. In this way, the nature, quantity and color of the liquids in each part can be more clearly understood, providing an accurate diagnostic basis for doctors. By separately collecting the drainage fluids from different parts in different containers, the risk of cross-infection between different liquids can be reduced, and the probability of the patient developing concurrent infections can be lowered. Medical staff can more conveniently observe the liquid conditions in each container, timely record the changes in the nature, quantity and color of the liquid, providing an important reference for the subsequent treatment of the patient. Using multiple drainage bags can better fix the drainage tube, reduce the movement and compression of the drainage tube in the patient's body, and reduce the discomfort of the patient. In actual use, the base 1 is usually placed on the ground, such as under the hospital bed. The clamp 4 is fixed on the edge of the hospital bed. The telescopic rod 3 can be telescopically adjusted to adapt to hospital beds of different heights. The end of the catheter passes through the flared opening 2 and is connected to the container. The structure is delicate and practical, ensuring the orderly connection of the catheters and reducing the interference between the catheters.

[0024] The main difference between this embodiment and the prior art is that this embodiment adopts, specifically to ensure the safe connection between the catheter and the container, after the catheter passes through the outer expansion port 2 and is connected to the container, the liquid inlet of the container needs to be placed on the lower side of the outer expansion port 2, because the first slider 603 slides in the arc groove 602, and the second slider 604 slides in the linear groove 1021, so that the disk 601 can drive the plurality of rubber blocks 605 to gather or spread when rotating. In the initial state, the rubber blocks 605 are in a spreading state. By toggling the first lever 606 to drive the disk 601 to rotate, the plurality of rubber blocks 605 can be controlled to gather, Thereby, the liquid inlet of the container is clamped, the position of the container is fixed, and the connection position between the catheter and the container is ensured not to be offset. The position of the end of the catheter can be firmly fixed to prevent it from falling off or shifting, and it can avoid falling off and loosening caused by excessive pulling, so as to avoid damage to the catheter or surrounding tissues, so that the patient can move freely within a safe distance after the operation. Moreover, the catheter needs to pass through the sliding sleeve 8. Through the dual limiting functions of the sliding sleeve 8 and the outer expansion mouth 2, the position of the catheter can be limited, the bending amplitude of the catheter can be reduced, and the catheter can be prevented from being blocked due to excessive bending, thereby ensuring that the liquid flows smoothly in the catheter and ensuring the treatment effect.

[0025] The above structure is the main structure of this embodiment, which solves the problem of interference caused by catheter bending, and the fixing mechanism 6 is an existing structure. The specific structure and connection method of the catheter and the container are not described in detail in this embodiment. In addition, how the catheter flows liquid also belongs to the existing technology. Therefore, this application does not make detailed limitations.

[0026] Reference Figures 5-8 The self-locking mechanism 7 includes a second lever 701, a pawl 702, a spring 703 and a ratchet 704. The second lever 701 is rotatably connected to the upper side of the base 1. The pawl 702 is located in the interlayer 102. The pawl 702 is fixedly connected to the rotating shaft surface of the second lever 701. The spring 703 is fixedly connected between the inner wall of the interlayer 102 and the pawl 702. The ratchet 704 is fixedly connected to the top of the disc 601, and the pawl 702 is meshed with the ratchet 704.

[0027] In this embodiment, it should be specifically noted that: the ratchet wheel 704 and the disc 601 are an integral structure. When the first lever 606 is toggled to drive the disc 601 to rotate, the ratchet wheel 704 will follow the disc 601 to rotate. The ratchet pawl 702 is used to block the counterclockwise rotation of the ratchet wheel 704. When the disc 601 rotates clockwise, several rubber blocks 605 gather together. At this time, the ratchet wheel 704 can rotate normally. When the first lever 606 is released, due to the blocking of the ratchet pawl 702, the ratchet wheel 704 cannot rotate counterclockwise, thereby fixing the position of the disc 601 after rotation, that is, fixing the position of the rubber blocks 605 after gathering. When it is necessary to take out the container, the second lever 701 can be toggled to drive the ratchet pawl 702 to rotate, so that the ratchet pawl 702 is separated from the ratchet wheel 704. At this time, the first lever 606 can be moved to drive the disc 601, the ratchet wheel 704 and the rubber blocks 605 back to their original positions. After the second lever 701 is released, under the elastic action of the spring 703, the second lever 701 and the ratchet pawl 702 return to their original positions again, realizing a self-locking structure for adjusting the first lever 606, ensuring that the liquid inlet of the fixed container will not loosen, which is beneficial to the stability of the connection between the catheter and the container.

[0028] Referring to Figures 1-3 , the guiding mechanism includes a sliding sleeve 8, a locking knob 801 and a guiding frame 802. The sliding sleeve 8 is slidably connected to the surface of the telescopic rod 3. The guiding frame 802 is fixedly connected to one side of the sliding sleeve 8 close to the outer expansion port 2. The locking knob 801 is installed on the other side of the telescopic rod 3. A number of guiding grooves 803 are provided on the guiding frame 802, and a reset bolt 804 is connected to the side of each guiding groove 803 through a coil spring.

[0029] In this embodiment, it should be specifically noted that: the locking knob 801 is used to fix the position of the sliding sleeve 8. Tightening the locking knob 801 provides frictional resistance to fix the position of the sliding sleeve 8. After loosening the locking knob 801, the sliding sleeve 8 can slide up and down on the surface of the telescopic rod 3, thereby adjusting the height of the guiding frame 802, which can be automatically adjusted according to the bending condition of the catheter, which is beneficial to the bending amplitude of the catheter. A number of guiding grooves 803 are designed, and the catheters can be passed through one by one. The automatic reset structure of the reset bolt 804 is designed, and the catheter can be easily passed through the guiding groove 803. The positions of a number of guiding grooves 803 corresponding to the catheter are designed to effectively adjust the bending amplitude of the catheter, prevent the blockage problem of the catheter, which is beneficial to subsequent replacement and maintenance, and helps to realize the standardization and normalization of medical operations.

[0030] Referring to Figure 4 , tightening knobs 301 are installed at the connections of the telescopic rod 3 with the base 1 and the fixture 4, and a rubber strip 302 is fixedly connected to one side of the telescopic rod 3 close to the locking knob 801.

[0031] In this embodiment, it should be specifically noted that: trunnions are installed at both ends of the telescopic rod 3. Through the trunnions, the connection angles between the base 1, the telescopic rod 3, and the clamp 4 can be adjusted, which is beneficial to expanding the position range of the base 1 during use and reducing the impact of the catheter on medical staff and patients. The trunnions can be locked by the tightening knob 301 to fix the connection angle of the telescopic rod 3, thereby fixing the approximate angle of the catheter. When not in use, the tightening knob 301 can be loosened to help the overall structure fold, facilitating storage and reducing the occupied volume.

[0032] Referring to Figure 4 , a clamping groove 401 is provided on the side of the clamp 4. A positioning plate 402 is slidably arranged in the clamping groove 401. The bottom of the clamp 4 is threadedly connected with a threaded knob 403, and the upper end of the threaded knob 403 is rotatably connected to the positioning plate 402.

[0033] In this embodiment, it should be specifically noted that: during installation, the clamping groove 401 is stuck on the edge of the hospital bed, and then the threaded knob 403 is rotated to drive the positioning plate 402 to move upward, thereby fixing the clamp 4 on the edge of the hospital bed. The surface of the positioning plate 402 is designed with anti-slip grooves, which can increase the frictional resistance and prevent the clamp 4 from falling off. The structure is simple and the operation is convenient.

[0034] Referring to Figure 3 , a guiding frame 9 is fixedly connected to the top of the clamp 4. The guiding frame 9 has an arc-shaped structure, and its end is located above the guiding frame 802.

[0035] In this embodiment, it should be specifically noted that: the guiding frame 9 is arc-shaped and is used to place the catheter. The catheter passes through the guiding frame 802 along the guiding frame 9, and the catheter passing through the guiding frame 9 will not be overly bent, which is beneficial to the smoother flow of the liquid in the catheter.

[0036] Referring to Figure 5 , elastic bands 5 are installed on both sides of the base 1. The ends of the two elastic bands 5 are fixedly connected with plug-in fasteners 501.

[0037] In this embodiment, it should be specifically noted that: the elastic bands 5 have an elastic structure. After the container is placed in the accommodation cavity 101, the two plug-in fasteners 501 are snapped together to initially fix the position of the container, preventing the position of the container from being affected by the shaking and tipping of the base 1 and ensuring the position safety of the container.

[0038] Referring to Figure 7 , an outlet groove 1022 is formed in the side wall of the interlayer 102. The first lever 606 passes through the outlet groove 1022 and extends outward.

[0039] In this embodiment, it should be specifically noted that: the outlet groove 1022 is used to limit the sliding of the first lever 606. The first lever 606 and the disc 601 are an integral structure, thereby limiting the rotation distance of the first lever 606, that is, the rotation angle of the disc 601.

[0040] Working principle of the present invention: The main problem solved by this embodiment is: by installing multiple containers in a plurality of accommodating chambers 101, multiple catheters can be connected accordingly, the positions of the overall catheters can be orderly, the problem of mutual interference between the catheters can be solved, and the connection position of the catheter is limited by the fixing mechanism 6 and the sliding sleeve 8, which solves the problem of possible bending and clogging of the catheter.

[0041] The specific steps are as follows: First, place the prepared container into the corresponding accommodating cavity 101, then pass the catheter through the outer expansion port 2 to connect with the corresponding container inlet, and check whether the connection is firm, then place the container inlet between several rubber blocks 605, turn the first lever 606 to drive the disc 601 to rotate, so that several rubber blocks 605 gather to clamp the container inlet, so that the catheter is firmly connected to the container, observe the catheter fluctuation, ensure smooth drainage, and ensure that the catheter liquid flows steadily, then pass the catheter through the guide frame 802, and place the catheter in the guide frame 9, install several catheters in turn according to the above operations, and after the installation is completed, place the base 1 in a safe position to prevent it from being kicked over and expanded, then regularly observe the color, shape, quality of the liquid in the catheter and the bleeding and exudation of the incision dressing, regularly replace the container, and maintain sterile operation.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
