Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a ureteral dilator assembly that can uniformly inflate a balloon. Background Technology

[0002] Ureteral dilator assemblies are commonly used medical devices in the treatment of urinary system diseases. However, ureteral dilator assemblies currently on the market have revealed many problems in practical applications and urgently need improvement.

[0003] Traditional ureteral dilator assemblies have flawed balloon inflatation mechanisms. During the process of inflating the balloon through fluid injection, inadequate fluid delivery path design often leads to uneven balloon inflating. This results in uneven force distribution across different parts of the balloon during ureteral dilation, failing to achieve the desired dilation effect and potentially causing ureteral damage. Furthermore, the balloon's thickness causes friction against the ureteral wall during insertion, hindering the insertion process. Utility Model Content

[0004] The present invention aims to solve the above-mentioned defects and provide a ureteral dilator assembly that can uniformly inflate a balloon.

[0005] To overcome the deficiencies in the prior art, the technical solution adopted by this utility model to solve its technical problem is: a ureteral dilator assembly that can uniformly inflate a balloon, including a balloon, one end of which is connected to a head and the other end of which is connected to an outer tube port to form a sealed space in the balloon. A connector is formed on the outer tube, and a delivery groove is formed on the inner wall of the outer tube. An inlet channel communicating with the delivery groove is formed in the connector, so that liquid is delivered into the balloon through the inlet channel and the delivery groove.

[0006] The inner tube, which passes through the outer tube and is connected to the head, forms a radially abrupt change in the region of the inner tube located within the balloon.

[0007] Further improvements include embedding a developing ring on the mutation portion.

[0008] Further improvements include using two developing rings.

[0009] Further improvements include the provision of a magnetic ring inside the connector that corresponds to and attracts the magnetic part on the inner tube.

[0010] Further improvements include axially disposed at least two elastic plates on the inner wall of the balloon.

[0011] The beneficial effects of this utility model are: This design expands the balloon by moving the outer tube, and the liquid filling the balloon can make it inflate evenly. While inflating, the outer tube will move slowly, and the elastic plate can be used to make the balloon fit against the inner tube. This effectively solves the problem that when the balloon is inserted into the ureter, its own thickness causes friction with the inner wall of the ureter during the insertion process, which in turn hinders the insertion operation.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort in accordance with the embodiments of the basic utility model are within the scope of protection of this utility model.

[0017] refer to Figure 1 and Figure 2 A ureteral dilator assembly capable of uniformly inflating a balloon includes a balloon 2, one end of which is connected to a head 1 and the other end to an outer tube 6 port to form a sealed space within the balloon 2. A connector 7 is formed on the outer tube 6, and a delivery groove 12 is provided on the inner wall of the outer tube 6. An inlet channel 8 communicating with the delivery groove 12 is provided in the connector 7, thereby delivering liquid into the balloon 2 through the inlet channel 8 and the delivery groove 12. Its working principle is that, through the inlet channel 8 and the delivery groove 12, the liquid can be smoothly delivered into the balloon 2, thereby realizing the inflation operation of the balloon 2.

[0018] The inner tube 9 passes through the outer tube 6 and is connected to the head 1. A radial abrupt change is formed on the area of ​​the inner tube 9 located within the balloon 2 to form a mutation section 3. A contrast ring 5 is embedded on the mutation section 3. The contrast ring 5 can be clearly visualized under medical imaging equipment. This is of great significance for doctors to monitor the position and status of the ureteral dilator assembly in the body in real time during the operation, which greatly improves the accuracy and safety of the operation. Preferably, there are two contrast rings 5.

[0019] In this embodiment, in order to ensure that the balloon 2 can be stably fixed in the expanded state to meet the actual use needs during the operation, the connector 7 is provided with a magnetic ring 10 that corresponds to and attracts the magnetic part 11 provided on the inner tube 9. The generated magnetic force can effectively keep the balloon 2 in the expanded state, and avoid unnecessary contraction or displacement of the balloon 2 due to various factors during the operation, thus providing a strong guarantee for the smooth progress of the operation.

[0020] In this embodiment, at least two elastic plates 4 are axially arranged on the inner wall of the balloon 2. The elastic plates 4 can assist the balloon 2 to expand evenly by virtue of their own elastic properties, ensuring that the balloon 2 is subjected to uniform force in all parts during the inflation process, avoiding the situation of excessive or insufficient local inflation, and providing a stable and reliable expansion effect for surgical operation.

[0021] Working principle: When the magnetic ring 10 and the magnetic part 11 are in an adsorption coupling state, the balloon 2, under the external force, i.e., the pulling action of the outer tube 6, tightly adheres to the surface of the inner tube 9. At this time, by injecting liquid into the inlet channel 8, the liquid flows into the delivery tank 12 and enters the balloon 2 along the inner tube 9. As the liquid is injected, the internal pressure of the balloon 2 gradually increases, and then it expands evenly. The tension generated after the balloon 2 expands will pull the outer tube 6 to move towards the head 1. When the outer tube 6 comes into contact with the abrupt change part 3, its displacement process stops. At this time, the balloon 2 continues to expand around the abrupt change part 3 as a preset area. At the same time, the magnetic ring 10 and the magnetic part 11 are in a misaligned decoupled state.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
