Description

Technical Field

[0001] This utility model relates to the field of ureteral balloon dilation technology, and in particular to an adjustable pressure ureteral balloon dilation catheter. Background Technology

[0002] The ureter connects the renal pelvis to the bladder and is a long, thin tube in the human body used for urine excretion. Clinical practice has shown that if a stone from the kidney is present in the ureter, it is very likely to cause the lumen of the ureter to become narrower than normal in part or in its entirety. In this case, although the ureter is not interrupted, it will lead to varying degrees of upper urinary tract obstruction and hydronephrosis.

[0003] A search revealed a ureteral dilation balloon catheter (authorization announcement number: CN 221771251 U), which "comprising a tube body, a distal end of which is provided with a catheter tip, a balloon disposed on the tube body, the distal end of which is connected to the catheter tip, a connector portion disposed at the proximal end of the tube body, and cutting grooves distributed spirally around the tube wall." This invention allows insertion into a narrow tube or cavity requiring dilation via the endoscope's instrument channel without a guidewire, simplifying the operation. It not only reduces the radial dimension of the catheter but also eliminates the need for guidewire guidance by directly connecting the balloon to the tube body, thus avoiding the need for X-ray positioning and enabling visualized operation. It is expected to exhibit better pushing performance and reduce the risk of ureteral damage during pushing.

[0004] Based on the aforementioned technologies, the applicant believes that existing balloon catheters lack a mechanism for adjusting balloon pressure, which has certain shortcomings in practical use. In response to the above problems, we have introduced an adjustable pressure ureteral balloon dilation catheter. Utility Model Content

[0005] This utility model discloses an adjustable pressure ureteral balloon dilation catheter, which aims to solve the technical problem that existing balloon catheters lack a mechanism for adjusting balloon pressure and have certain shortcomings in practical use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An adjustable pressure ureteral balloon dilation catheter includes a catheter body, one end of which is fixedly connected to a drainage ball, and the other end of which is provided with an adjustment frame. An adjustment mechanism is provided on the outer side of the catheter body, comprising a first adjustment component, a second adjustment component, and a stabilizing component. These components cooperate with each other. The first adjustment component includes a threaded rod threadedly connected to the top of the adjustment frame. A connecting plate is rotatably connected to the bottom of the threaded rod, and a connecting frame is fixedly connected to the bottom of the connecting plate. A pressing roller is rotatably connected inside the connecting frame, and a rotating disk is fixedly connected to the top of the threaded rod. The threaded rod and the rotating disk cooperate with each other.

[0008] The adjustable mechanism allows for rapid and effective regulation of the flow rate and pressure of the medication inside the catheter body to suit the needs of different patients. This avoids discomfort caused by unadjustable pressure, improves the effectiveness of the balloon, and features a simple structure and strong practicality.

[0009] In a preferred embodiment, the second adjustment component includes a connecting tube disposed on the outside of the conduit body. A connector is fixedly connected to the outside of the connecting tube and to the conduit body. A first conduit head is fixedly connected to the outside of the connecting tube, and a second conduit head is fixedly connected to the top of the connecting tube. The size of the first conduit head is larger than that of the second conduit head, and the first and second conduit heads are used in conjunction with each other.

[0010] By setting up No. 1 and No. 2 catheter tips, different sizes of syringes can be used to meet the needs of different patients.

[0011] In a preferred embodiment, the stabilizing component includes a slid groove symmetrically formed inside the connecting frame. Stabilizing wheels are slidably connected inside both connecting frames. A connecting post is symmetrically rotatably connected to the outer side of the pressing roller, and the connecting post is fixedly connected to the stabilizing wheel.

[0012] The stabilizing wheel slides downward inside the groove, making the downward movement of the pressing roller more stable and preventing wobbling and deviation.

[0013] In a preferred embodiment, the bottom of the inner wall of the connecting frame is symmetrically fixed with fixing posts, and the top of each of the two fixing posts is fixed with a stabilizing ring, which is used in conjunction with the conduit body.

[0014] By using fixed posts and stabilizing rings, the main body of the catheter can be positioned to prevent it from shaking inside the connecting frame.

[0015] In a preferred embodiment, a cylindrical balloon is fixedly connected to the outer side of the catheter body and to the end near the drainage ball, and an expansion column is fixedly connected to the outer side of the cylindrical balloon.

[0016] By using a cylindrical balloon and expansion column, the expansion area is larger and the expansion support effect is better compared to a spherical balloon.

[0017] In a preferred embodiment, the outer side of the rotating disk is provided with anti-slip grooves arranged in a circumferential array for anti-slip purposes.

[0018] The anti-slip grooves prevent hands from slipping and increase friction.

[0019] The adjustable pressure ureteral balloon dilation catheter provided by this utility model has the following advantages:

[0020] Firstly, the adjustable mechanism can effectively and quickly adjust the flow rate and pressure of the drug solution inside the catheter body to meet the needs of different patients, avoid discomfort caused to patients due to unadjustable pressure, improve the effectiveness of balloon use, and has a simple structure and strong practicality.

[0021] Secondly, the fixed column and stabilizing ring can be used to position the catheter body and prevent it from shaking inside the connecting frame.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0029] The adjustable pressure ureteral balloon dilation catheter disclosed in this utility model is mainly used in ureteral balloon dilation scenarios.

[0030] Reference Figure 1 - Figure 5An adjustable pressure ureteral balloon dilation catheter includes a catheter body 1, with a drainage ball 3 fixedly connected to one end of the catheter body 1. An adjustment frame 2 is provided on the outer side of the other end of the catheter body 1. An adjustment mechanism is provided on the outer side of the catheter body 1. The adjustment mechanism includes a first adjustment component, a second adjustment component, and a stabilizing component. The first adjustment component, the second adjustment component, and the stabilizing component work together. The first adjustment component includes a threaded rod 41, which is threadedly connected to the top of the adjustment frame 2. A connecting plate 44 is rotatably connected to the bottom of the threaded rod 41. A connecting frame 43 is fixedly connected to the bottom of the connecting plate 44. A pressing roller 45 is rotatably connected inside the connecting frame 43. A rotating disk 42 is fixedly connected to the top of the threaded rod 41. The threaded rod 41 and the rotating disk 42 work together. The second adjustment component includes a connecting pipe 8, which is located on the outside of the conduit body 1. A connector 9 is fixedly connected to the outside of the connecting pipe 8, and the connector 9 is fixedly connected to the conduit body 1. A first conduit head 10 is fixedly connected to the outside of the connecting pipe 8, and a second conduit head 11 is fixedly connected to the top of the connecting pipe 8. The size of the first conduit head 10 is larger than the size of the second conduit head 11. The first conduit head 10 and the second conduit head 11 are used in conjunction with each other. The stabilizing component includes a sliding groove 5, which is symmetrically opened inside the connecting frame 43. Stabilizing wheels 7 are slidably connected inside both connecting frames 43. A connecting post 6 is symmetrically rotatably connected to the outside of the pressing roller 45, and the connecting post 6 is fixedly connected to the stabilizing wheel 7.

[0031] In this embodiment, the syringe is connected to either catheter tip 10 or catheter tip 11, depending on the patient's needs. Then, saline solution is injected into the catheter body 1. The saline solution expands the balloon 12 and the expansion column 13. During expansion, if the flow rate and pressure of the fluid need to be adjusted, the operator rotates the rotating disk 42. The rotation of the rotating disk 42 drives the threaded rod 41 to rotate, which in turn moves the connecting frame 43 downwards. The connecting frame 43 then moves the pressing roller 45 downwards, thus pressing the catheter body 1 and adjusting the flow rate and pressure of the fluid. As the pressing roller 45 moves downwards, the stabilizing wheel 7 slides downwards within the groove 5, making the downward movement of the pressing roller 45 more stable and preventing shaking or deviation. Through the adjustable mechanism, the flow rate and pressure of the medication inside the catheter body 1 can be effectively and quickly adjusted to suit the needs of different patients, avoiding discomfort caused by unadjustable pressure. This improves the effectiveness of the balloon, and the structure is simple and highly practical.

[0032] The above technical solution addresses the issue that existing balloon catheters lack a mechanism for adjusting balloon pressure, resulting in certain shortcomings in practical use. To resolve these issues, the specific operation is as follows:

[0033] Reference Figure 1 - Figure 5 In a preferred embodiment, fixing posts 46 are symmetrically fixed to the bottom of the inner wall of the connecting frame 43, and stabilizing rings 47 are fixedly connected to the top of each fixing post 46. The stabilizing rings 47 cooperate with the catheter body 1. A cylindrical balloon 12 is fixedly connected to the outer side of the catheter body 1, near the end of the unblocking ball 3, and an expansion post 13 is fixedly connected to the outer side of the cylindrical balloon 12. The outer side of the rotating disk 42 is provided with anti-slip grooves arranged in a circumferential array for anti-slip purposes.

[0034] In this embodiment, the fixed column 46 and stabilizing ring 47 can be used to position the catheter body 1 and prevent the catheter body 1 from shaking inside the connecting frame 43. The cylindrical balloon 12 and expansion column 13 provide a larger expansion area and better expansion support compared to a spherical balloon. The anti-slip groove can prevent slippage and increase friction.

[0035] Working principle: In actual use, the operator first slowly inserts the catheter body 1 into the patient's affected area, then connects the syringe to either the first catheter head 10 or the second catheter head 11, depending on the patient's needs. Then, saline solution is injected into the catheter body 1. The saline solution expands the balloon 12 and the expansion column 13. During expansion, if the flow rate and pressure of the fluid need to be adjusted, the operator rotates the rotating disk 42. The rotation of the rotating disk 42 drives the threaded rod 41 to rotate, which in turn moves the connecting frame 43 downwards. The connecting frame 43 then moves the pressing roller 45 downwards, thus pressing the catheter body 1 and adjusting the flow rate and pressure of the fluid. As the pressing roller 45 moves downwards, the stabilizing wheel 7 slides downwards inside the groove 5, making the downward movement of the pressing roller 45 more stable and preventing shaking or deviation.

[0036] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
