Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a medical urological dilation and drainage device. Background Technology

[0002] The purpose of urethral drainage is to drain urine from the bladder to protect the kidneys and relieve the patient's pain. For patients who cannot urinate on their own, have problems with their urinary tract, or are in a coma, a ureter is needed to drain urine from the bladder. The ureter can be inserted through the urethral opening at the genitals. Once the ureter is in the bladder, the balloon at the end of the ureter can inflate to prevent the ureter from dislodging and to avoid urine leakage.

[0003] Currently, most clinical surgeries involving ureteral implantation involve doctors directly inserting the ureter into the patient's body. The ureter is made of soft silicone, and the doctor manually adjusts the urethral angle during insertion to ensure smooth passage into the bladder. However, when there is trauma, infection, prostate infection, or urethral stricture in the patient's urethra, the soft ureter may not be able to be directly cleared into the bladder, requiring a urethral dilation procedure. Currently, dilation needles are often used clinically to clear the urethra. These dilation needles are typically metal rods with a fixed bend angle. However, using dilation needles for ureteral dilation can cause pain to the patient due to the angle and diameter of the needle. Furthermore, the repeated sliding of the fixed-angle dilation needle in the urethra can cause compression and friction, resulting in multiple injuries to the urethra. Therefore, a drainage device that can dilate the urethra while minimizing urethral damage is needed. Summary of the Invention

[0004] This invention proposes a medical urological dilation and drainage device to solve the problem that the urethra may be repeatedly damaged during the urinary tract dilation process in the prior art.

[0005] The technical solution of the present invention is as follows: A medical urological dilation and drainage device includes a ureter and a balloon. The balloon is fixedly disposed on the outside of one end of the balloon. An injection tube and a medication injection tube are provided on the end of the ureter away from the balloon. The device also includes a Y-shaped handle, a draining rod, a balloon-ball mechanism, and a clamping mechanism. The Y-shaped handle is centrally located and consists of one main branch and two branches. The end of the ureter away from the balloon is detachably connected to the main branch of the Y-shaped handle. The draining rod is detachably connected to the Y-shaped handle and passes through one branch of the Y-shaped handle and the ureter. The draining rod is made of a soft, elastic material and has a three-section design. The balloon-ball mechanism is fixedly connected to the end of the draining rod away from the Y-shaped handle. The balloon mechanism passes through the ureter and is used to expand and compress the urethra. One end of the balloon mechanism, which is fixedly connected to the unblocking rod, extends out of the ureter away from the Y-shaped handle. The balloon mechanism and the unblocking rod extend out of the Y-shaped handle at two branches, respectively. When the unblocking rod and the balloon mechanism slide relative to each other, the balloon mechanism can expand to dilate the urethra. Both branches on the Y-shaped handle are detachably connected to the clamping mechanism. The unblocking rod and the balloon mechanism are both detachably connected to the clamping mechanism. The clamping mechanism is used to drive the unblocking rod and the balloon mechanism to move, allowing the unblocking rod and the balloon mechanism to be withdrawn from the ureter.

[0006] The unblocking rod is equipped with an unblocking ball, a first support rod section, a second support rod section, and a third support rod section. The unblocking ball is fixedly connected to the end of the unblocking rod away from the Y-shaped handle. The balloon ball mechanism is fixedly connected to the unblocking ball. The first support rod section passes through one branch of the Y-shaped handle and through the ureter. The first support rod section is detachably connected to the clamping mechanism. The second support rod section is fixedly connected to the end of the first support rod section away from the clamping mechanism. The balloon ball mechanism is slidably connected to the second support rod section. The third support rod section is fixedly connected to the side of the second support rod away from the first support rod section. The end of the third support rod away from the second support rod section is fixedly connected to the unblocking ball.

[0007] The balloon-ball mechanism includes an umbrella-shaped assembly, a spherical sleeve, and an adjusting rod. The umbrella-shaped assembly is fixedly connected to the unblocking ball, and the spherical sleeve is fitted onto the umbrella-shaped assembly. The umbrella-shaped assembly is used to expand and open the spherical sleeve. The spherical sleeve is fixedly connected to the unblocking ball and is made of a soft and elastic material. The adjusting rod is fixedly connected to the umbrella-shaped assembly and is also made of a soft and elastic material. The adjusting rod is fixedly connected to one end of the spherical sleeve away from the unblocking ball. The adjusting rod passes through the ureter and a branch of the Y-shaped handle. When the adjusting rod is in the ureter, it fits against the unblocking rod.

[0008] The umbrella-shaped component includes multiple elastic wires arranged in a ring around the drain ball, with one end of each elastic wire away from the drain ball being fixedly connected to the adjusting rod.

[0009] Multiple elastic wires are arranged around the third support rod segment, which is located within the spherical sleeve. The end of the adjusting rod that is fixedly connected to the elastic wire is configured as an annular shape and is sleeved on the second support rod segment. The adjusting rod is slidably connected to the second support rod segment.

[0010] The elastic wire is provided with an arc-shaped segment one and an arc-shaped segment two. The arc-shaped segment one is fixedly connected to the unclogging ball. When the elastic wire bends, the bending direction of the arc-shaped segment one is away from the support rod segment three. The arc-shaped segment two is fixedly connected to the end of the arc-shaped segment one away from the unclogging ball. When the elastic wire bends, the bending direction of the arc-shaped segment one is towards the support rod segment three.

[0011] The two branches of the Y-shaped handle are each provided with a conical groove, and the unblocking rod and the adjusting rod extend out of the two conical grooves respectively.

[0012] The clamping mechanism includes a first conical clamp and a second conical clamp. The first conical clamp is detachably connected to one of the conical grooves. The unblocking rod passes through the first conical clamp. The second conical clamp is detachably connected to the other conical groove. The adjusting rod passes through the second conical clamp.

[0013] When the adjusting rod slides relative to the unclogging rod toward the unclogging ball, the elastic wire is squeezed and bent, which compresses and expands the spherical sleeve. The expansion diameter of the spherical sleeve on the side closer to the unclogging ball is larger than that on the side closer to the adjusting rod.

[0014] The working principle and beneficial effects of this invention are as follows: 1. In this invention, a dredging rod is set up. The dredging rod is the part that first extends into the urethra. Because it is thin and soft, it can enter the narrow gap of the urethra. Due to its soft design, the urethra does not need to be kept at a fixed angle for operation, which reduces the damage to the urethra. 2. In this invention, by setting up a balloon mechanism, the balloon enters the narrower part of the urethra under the drive of the unblocking rod. At this time, it expands to dilate the urethra, avoiding the impact and compression on the urethra caused by directly squeezing the dilator needle into the urethral gap, thus further reducing damage. 3. In this invention, by setting a draining rod, the balloon mechanism can be driven into the narrower part of the urethra. By setting the balloon mechanism, the urethra can be expanded at the narrower part of the urethra, thus avoiding the traditional method of forcibly expanding the urethra by squeezing it. The expansion method used in this application can control the size of the balloon mechanism's expansion and adjust the degree of urethral expansion. Moreover, the balloon mechanism is very small before expansion, which can avoid direct impact on the urethra and damage when inserted into the narrow urethra. At the same time, the ureter, adjusting rod, and draining rod are all made of soft materials, which will not squeeze the patient's urethra to a fixed angle, further protecting the patient's urethra.

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. Example 1

[0019] like Figures 1-6As shown, this embodiment proposes a medical urological dilation and drainage device, including a ureter 1 and a balloon 2. The balloon 2 is fixedly installed on the outside of one end of the balloon 2. An injection tube 3 and a drug injection tube 4 are provided on the end of the ureter 1 away from the balloon 2. It also includes a Y-shaped handle 5, a drainage rod, a balloon-ball mechanism, and a clamping mechanism. The Y-shaped handle 5 is centrally located and consists of one main stem and two branches. The end of the ureter away from the balloon 2 is detachably connected to the main stem of the Y-shaped handle 5. The drainage rod is detachable. Connected to the Y-shaped handle 5, the drain rod passes through one branch of the Y-shaped handle 5 and the ureter 1, and is arranged in three sections. The drain rod passes through the ureter 1, and a balloon mechanism is fixedly connected to the end of the drain rod away from the Y-shaped handle 5. The balloon mechanism passes through the ureter 1 and is used to expand and compress the urethra. The end of the balloon mechanism fixedly connected to the drain rod extends out of the ureter 1 away from the Y-shaped handle 5. The Y-shaped handle 5 extends from two branches of the unblocking rod. When the unblocking rod slides relative to the balloon mechanism, the balloon mechanism can expand to dilate the urethra. Both branches of the Y-shaped handle 5 are detachably connected to the clamping mechanism. Both the balloon mechanism and the unblocking rod are detachably connected to the clamping mechanism. By pushing the Y-shaped handle 5, the ureter 1 can be moved. The unblocking rod and the balloon mechanism can be withdrawn from the ureter 1. In this application, the unblocking rod drives the balloon mechanism to move before the ureter 1. The balloon and dilator are thinner and can be inserted into the urethral crevice with minimal damage. Then, the clamping mechanism controls the expansion of the balloon end inserted into the urethra to open the urethra, and then the ureter 1 is pushed forward. Through repeated operation, the ureter 1 moves forward in the urethra, and the balloon mechanism performs peristaltic movement, avoiding compression and damage to the narrow part of the urethra. This is a more efficient method than the traditional method of using a dilator needle to directly insert into the urethra to dilate it.

[0020] like Figures 1-5As shown, the unblocking rod is equipped with an unblocking ball 6, a first support rod section 7, a second support rod section 8, and a third support rod section 9. The unblocking ball 6 is fixedly connected to the end of the unblocking rod away from the Y-shaped handle 5. The balloon mechanism is fixedly connected to the unblocking ball 6. The first support rod section 7 passes through one branch of the Y-shaped handle 5 and through the ureter 1. The first support rod section 7 is detachably connected to the clamping mechanism. The second support rod section 8 is fixedly connected to the end of the first support rod section 7 away from the clamping mechanism. The balloon mechanism is slidably connected to the second support rod section 8. The third support rod section 9 is fixedly connected to the side of the second support rod section 8 away from the first support rod section 7. The third support rod section 9 is also fixedly connected to the side of the second support rod section 8 away from the second support rod section 8. One end is fixedly connected to the unblocking ball 6, and the unblocking ball 6 is set in the gap of the urethra at the front end. The ball-shaped front end can avoid scratching. At the same time, the third support rod segment 9, together with the umbrella-shaped component, first extends into the gap of the urethra. The third support rod segment 9 is more flexible and slender. The umbrella-shaped component slides on the second support rod segment 8 to open the ball sleeve 10. The surface of the second support rod segment 8 is smoother. The first support rod segment 7 is used to push the umbrella-shaped component and the unblocking ball 6. The elasticity is relatively high. Pushing the unblocking rod can drive the unblocking ball 6 and the umbrella-shaped component to slide into the urethra. Then, by pushing the Y-shaped handle 5, the ureter 1 is pushed to move.

[0021] like Figures 2-5As shown, the balloon-ball mechanism includes an umbrella-shaped assembly, a spherical sleeve 10, and an adjusting rod 11. The umbrella-shaped assembly is fixedly connected to the unblocking ball 6, and the spherical sleeve 10 is fitted onto the umbrella-shaped assembly. The umbrella-shaped assembly is used to expand and open the spherical sleeve 10. The spherical sleeve 10 is fixedly connected to the unblocking ball 6 and is made of a soft and elastic material. The adjusting rod 11 is fixedly connected to the umbrella-shaped assembly and is also made of a soft and elastic material. The adjusting rod 11 is fixedly connected to the end of the spherical sleeve 10 away from the unblocking ball 6. The adjusting rod 11 passes through a branch of the ureter 1 and the Y-shaped handle 5. When the adjusting rod 11 is in the ureter 1, it fits against the unblocking rod. The umbrella-shaped assembly includes multiple elastic wires, which are arranged in a ring around the unblocking ball 6. The end of the elastic wire away from the unblocking ball 6 is fixedly connected to the adjusting rod 11. The multiple elastic wires are arranged around the support rod segment 9, which is located within the spherical sleeve 10. The end of the adjusting rod 11 fixedly connected to the elastic wire is annular and fitted with... The adjusting rod 11 is slidably connected to the second support rod section 8. When the adjusting rod 11 slides relative to the unblocking rod towards the unblocking ball 6, the elastic wire is compressed and bent, causing the spherical sleeve 10 to expand. The expansion diameter of the spherical sleeve 10 on the side closer to the unblocking ball 6 is larger than that on the side closer to the adjusting rod 11. When the unblocking rod is fixed, the umbrella-shaped component is pushed by the adjusting rod 11, and the adjusting rod 11 slides on the second support rod section 8. At this time, the elastic wire is compressed. The elastic wire has a certain curvature. At this time, the elastic wire bends under the compression force, causing the elastic wire to open the spherical sleeve 10 outward, making the diameter of the spherical sleeve 10 larger, thereby opening the urethra. At this time, the adjusting rod 11 is fixed and pushes the unblocking rod. The unblocking rod drives the unblocking ball 6 to move into the urethra, stretching the umbrella-shaped component so that the elastic wire gradually approaches the third support rod section 9. The elastic wire becomes straighter, and at this time the diameter of the spherical sleeve 10 is smaller, allowing it to extend into the gap of the urethra.

[0022] like Figures 4-5 As shown, the elastic wire is provided with an arc-shaped segment 12 and an arc-shaped segment 13. The arc-shaped segment 12 is fixedly connected to the unblocking ball 6. When the elastic wire bends, the bending direction of the arc-shaped segment 12 is away from the support segment 3 9. The arc-shaped segment 13 is fixedly connected to the end of the arc-shaped segment 12 away from the unblocking ball 6. When the elastic wire bends, the bending direction of the arc-shaped segment 12 is towards the support segment 3 9. When the elastic wire is squeezed, the arc-shaped segment 12 opens outward and expands the spherical sleeve 10. The arc-shaped segment 13 is pulled by the arc-shaped segment 12 and separates from the support segment 3 9. However, because the bending direction is opposite, the diameter of the opening of the end of the spherical sleeve 10 away from the unblocking ball 6 is smaller, which makes it easier to push the ureter 1 forward. The ureter 1 can be pushed forward to the position that wraps around the support segment 2 8. At this time, the diameter of the urethra near the support segment 2 8 also expands due to the expansion of the spherical sleeve 10, and the ureter 1 can enter.

[0023] like Figure 1 and Figure 6 As shown, each of the two branches of the Y-shaped handle 5 has a conical groove 16. The unblocking rod and the adjusting rod 11 extend out of the two conical grooves 16 respectively. The clamping mechanism includes a first conical clamp 14 and a second conical clamp 15. The first conical clamp 14 is detachably connected to one of the conical grooves 16, and the unblocking rod passes through the first conical clamp 14. The second conical clamp 15 is detachably connected to the other conical groove 16, and the adjusting rod 11 passes through the second conical clamp 15. Both the first conical clamp 14 and the second conical clamp 15 can be manually pressed to clamp and fix the unblocking rod and the adjusting rod 11 respectively. The first conical clamp 14 and the second conical clamp 15 extend into the conical grooves 16. When the ureter is in a clamped state, the unblocking rod, adjusting rod 11 and ureter 1 will not slide relative to each other. This can be set up when the urethra is unobstructed. Push the Y-shaped handle 5 to deliver the ureter 1 into the urethra. When the urethra is narrow, the conical clamp 14 and conical clamp 2 15 can be separated from the conical groove 16. By pressing the conical clamp 14 and conical clamp 2 15, the unblocking rod and adjusting rod 11 can be clamped and fixed respectively. After the urethra is expanded by alternately pushing the unblocking rod and adjusting rod 11, push the Y-shaped handle 5 to send the ureter 1 in. Repeat the operation to make the ureter 1 pass through the narrow part of the urethra.

[0024] In this embodiment, the unblocking rod and adjusting rod 11 pass through the ureter 1 and extend out through the conical groove 16 on the Y-shaped handle 5. The unblocking rod and adjusting rod 11 pass through the conical clamp 14 and conical clamp 2 15 respectively. The conical clamp 14 and conical clamp 2 15 are both aligned with the conical groove 16. Then, the ureter 1 is aligned with the Y-shaped handle 5. The ball sleeve 10 and the ureter 1 are inserted into the urethra. The Y-shaped handle 5 is pushed to make the ball sleeve 10 and the ureter 1 move in the urethra. When encountering a narrow part of the urethra, the conical clamp 14 and conical clamp 2 15 are separated from the conical groove 16. The conical clamp 14 is pressed to push the unblocking rod, and the support rod segment 3 9 is pushed. The unblocking ball 6, the elastic wire, and the spherical sleeve 10 are inserted into the urethral crevice. At this time, the conical clamp 14 remains stationary, and the conical clamp 2 15 is pressed to push the adjusting rod 11. The adjusting rod 11 pushes the elastic wire, and the arc-shaped segment 12 and arc-shaped segment 2 13 are squeezed and bent to open the spherical sleeve 10. The end of the spherical sleeve 10 near the unblocking ball 6 is opened to open the urethra. At this time, the Y-shaped handle 5 is pushed, and the ureter 1 moves towards the elastic wire. After the ureter 1 wraps around the support segment 2 8, the unblocking rod is pushed, and the unblocking ball 6 continues to move into the urethra and stretches the elastic wire into a straight state. Through repeated movements, the ureter 1 passes through the narrower part of the urethra. Example 2

[0025] The Y-shaped handle 5 in this application can be improved by using motors to drive the unblocking rod, adjusting rod 11, and ureter 1 to move. Multiple motors drive the unblocking rod, adjusting rod 11, and ureter 1 to extend a short distance into the urethra, completing the peristaltic movement of the ball sleeve 10 and continuously dilating the urinary tract. After the ball sleeve 10 dilates the urinary tract, the ureter 1 moves a certain distance. Then, the unblocking rod pushes the unblocking ball 6 into the gap of the urinary tract. By repeatedly performing the above operation, the ureter 1 can be quickly delivered into the bladder. The motor control can reduce the difficulty of operation for medical staff and improve the efficiency of dilation and drainage.

[0026] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
