Description

Technical Field

[0001] The present invention relates to the technical field of postoperative rehabilitation, in particular to a postoperative protective stent for urology surgery. Background Art

[0002] The urinary system is a complex system of cavities that connect to the outside world and is responsible for the production and excretion of urine. If obstruction occurs, it can cause a series of pathological changes. Therefore, when obstruction occurs, medical staff usually use drainage tube surgery to drain the patient's urine. After the surgery, a protective stent is needed to secure the position of the drainage tube to prevent it from falling off.

[0003] The existing urology postoperative protective stents on the market usually only fix the position of the drainage tube to protect it from being pulled by external force and causing it to fall off during use. However, after the drainage tube operation is completed, residual tissue fluid and blood clots are prone to uncontrolled outflow from the wound surface of the drainage tube. If they are not cleaned in time, it is easy to cause the drainage tube to be blocked. However, cleaning the blood clots in the tube requires continuous squeezing of the tube wall, which can easily cause the blood clots and drainage materials to flow back to the end of the drainage tube close to the patient, which has certain risks. Moreover, it is not easy to expel the blood clots from the drainage tube by squeezing alone. Therefore, a urology postoperative protective stent is needed to solve the above problems.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the present invention, during the process of clearing the drainage tube, the electric push rod is started to first deform and bend the target position of the drainage tube, which serves as the first position to block backflow. As the electric push rod continues to extend, the bent position is clamped by two clamping plates, causing the drainage tube to be pressed and deformed on the basis of being bent, so that the inner wall of the drainage tube cannot flow tissue fluid, which serves as the second position to block backflow, so that the drainage tube is cut off at two places to prevent the blockage from flowing back during the subsequent cleaning process.

[0019] 2. In the present invention, the electric push rod is continued to be started, and the corresponding second resistance block squeezes the drainage tube in the middle together, and the blocked thrombus in the drainage tube is deformed or crushed by squeezing. The squeezing causes the corresponding position of the drainage tube to deform, and the internal fluid starts to flow. At this time, the third resistance block squeezes the outer wall of the drainage tube and slides and smoothes the deformed drainage tube while squeezing the drainage tube. After the thrombus blockage at the corresponding position of the drainage tube is squeezed and deformed, it is smoothed in the direction of the drainage tube transporting the urine bag, and the thrombus blockage is pushed toward the urine bag.

[0020] 3. In the present invention, since the inclined directions of each two second chutes are arranged relative to each other, when some stubborn thrombus blockages still cannot move after being squeezed, the two adjacent third resistance blocks will reciprocate and squeeze in opposite directions while smoothing and pushing the drainage tube, causing the drainage tube in this section to be pushed and deformed from both sides toward the middle position, and the thrombus therein is pressed and crushed by the left and right sides.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Example 1: This example aims to solve the problem that the thrombus in the drainage tube needs to be squeezed continuously, which may cause the thrombus and drainage material to flow back to the end of the drainage tube close to the patient, which has certain risks. Moreover, it is difficult to expel the thrombus from the drainage tube by squeezing alone. Figure 1 - Figure 12A postoperative protective stent for urological surgery includes a protective stent body 1, an outer wall of the protective stent body 1 is fixedly connected to a first fixing frame 4, an inner wall of the protective stent body 1 is slidably connected to a drainage tube 6, an inner wall of the first fixing frame 4 is fixedly connected to a second fixing frame 19, and the drainage tube 6 passes through the inner walls of the first fixing frame 4 and the second fixing frame 19;

[0036] The inner wall of the first fixed frame 4 is threadedly connected to a bolt 5, one end of the bolt 5 is rotatably mounted on a moving block 8, the outer wall of the moving block 8 is fixedly mounted on an electric push rod 9, the output end of the electric push rod 9 is fixedly connected to a first guide rod 10, the outer wall of the first guide rod 10 is fixed to a fixing frame 11, the outer wall of the fixing frame 11 is fixedly connected to a second guide rod 12, and the end of the second guide rod 12 is rotatably mounted on a first ball bearing 13;

[0037] The outer wall of the second fixed frame 19 is fixedly connected to the first guide rod 17 , the outer wall of the first guide rod 17 is slidably connected to the moving plate 14 , and the outer wall of the moving plate 14 is rotatably mounted with the rotating cylinder 15 .

[0038] A first return spring 18 is sleeved on the outer wall of the first guide rod 17 , one end of the first return spring 18 is fixed to the outer wall of the movable plate 14 , and the other end of the first return spring 18 is fixed to the outer wall of the second fixing frame 19 ;

[0039] A spiral groove 16 is formed on the outer wall of the rotating cylinder 15 , and the first ball 13 is slidably mounted in the spiral groove 16 .

[0040] A first sliding groove 20 is provided at one end of the rotating cylinder 15, and the inner wall of the first sliding groove 20 is fixedly connected to the second guide rod 21, and the outer wall of the second guide rod 21 is slidably connected to two sliders 22, and the outer wall of the slider 22 is fixedly connected to the second return spring 24, and the second return spring 24 is sleeved on the outer wall of the second guide rod 21.

[0041] The outer wall of the slider 22 is fixedly connected to a clamping plate 23 , and the outer wall of the clamping plate 23 is rotatably mounted with a plurality of rollers 25 that are evenly distributed.

[0042] In this embodiment: when using the urological surgery postoperative protective stent, the patient's drainage tube 6 is first inserted into the first fixed frame 4, and one end of the drainage tube 6 passes through the first fixed frame 4 and enters the second fixed frame 19, and then passes through the second fixed frame 19 to the outside, completing the preliminary position restriction of the drainage tube, and then the drainage tube is connected to the urine bag.

[0043] When the medical staff observes that the color of the liquid in the drainage tube has changed and needs to take cleaning measures in the drainage tube 6, the bolt 5 is rotated at this time. Through the threaded connection between the bolt 5 and the inner wall of the first fixed frame 4, the bolt 5 is continuously rotated into the first fixed frame 4. The movement of the bolt 5 brings the moving block 8 installed on its end to move synchronously. The movement of the moving block 8 brings the electric push rod 9 and the first guide rod 10 at its output end to move synchronously. The movement of the first guide rod 10 brings the fixed frame 11 and the second guide rod 12 to move synchronously, which promotes the synchronous movement of the first ball 13 at the end of the second guide rod 12. In the spiral groove 16 on the outer wall of the rotating cylinder 15, when the first ball 13 moves, the rotating cylinder 15 will rotate along the rotating connection of the movable plate 14 to adapt to the sliding of the first ball 13 in the spiral groove 16. The rotation of the rotating cylinder 15 causes the two clamping plates 23 to rotate synchronously, and part of the drainage tube 6 is located between the two clamping plates 23. The rotation of the two clamping plates 23 will twist the middle drainage tube 6, causing the corresponding position of the drainage tube 6 to be twisted and bent. The twisting and bending of the corresponding position of the drainage tube 6 causes the drainage tube 6 to be cut off from here, and the twisting and bending causes the position of the drainage tube 6 to be fixed while it is deformed.

[0044] Then the electric push rod 9 is started, prompting the second guide rod 12 to continue to move with the first ball 13, so that the rotating cylinder 15 rotates more. At this time, due to the rotation of the two clamping plates 23, the two third guide rods 38 will rotate synchronously. The circumferential rotation of the third guide rods 38 drives the second ball 26 to slide along the first track groove 36, prompting the second ball 26 to gradually slide from the first track groove 36 to the second track groove 37, as shown in the attached figure. Figure 7 As shown in the figure, since the first track groove 36 slides into the flat and gentle second track groove 37, the two second balls 26 and the third guide rod 38 are forced to move closer to each other. The mutual approach of the third guide rod 38 will bring the two clamping plates 23 closer to each other. At this time, the two clamping plates 23 will further press the bent drainage tube 6 to completely block the drainage tube 6.

[0045] It should be noted that when the drainage tube 6 is cleared of blockages, the target position of the drainage tube 6 is bent and blocked, and on the basis of bending and blocking, the bent part can be pressed and deformed. The two blocking measures are used to ensure that the fluid and thrombus in the drainage tube 6 are not easy to flow back during the clearing process.

[0046] Example 2: This example is based on Example 1. Figure 1 - Figure 12A postoperative protective bracket for urological surgery, one end of the clamping plate 23 is fixedly connected to the third guide rod 38, the end of the third guide rod 38 is rotatably installed with the second ball 26, the inner wall of the first fixed frame 4 is provided with a first track groove 36 and a second track groove 37, the first track groove 36 and the second track groove 37 are connected to each other, and the second ball 26 is slidably installed on the inner wall of the first track groove 36.

[0047] One end of the first guide rod 10 is fixedly connected to a first interference block 39, and the end of the first interference block 39 is provided with a first interference surface 27. The first guide rod 10 is slidably connected to the inner wall of the second fixed frame 19, and the inner wall of the second fixed frame 19 is fixedly connected to a plurality of evenly distributed second interference blocks 28.

[0048] A plurality of second sliding grooves 29 are provided on the inner wall of the second fixed frame 19, and a third guide rod 30 is fixedly connected to the inner wall of the second sliding groove 29, and a third return spring 31 is sleeved on the outer wall of the third guide rod 30, and one end of the third return spring 31 is fixed to the inner wall of the second sliding groove 29, and a fourth guide rod 32 is slidably connected to the outer wall of the third guide rod 30, and the outer wall of the fourth guide rod 32 is fixedly connected to the other end of the third return spring 31.

[0049] One end of the fourth guide rod 32 is fixedly connected to the third contact block 33 , and an outer wall of the third contact block 33 is fixedly connected to a protrusion 34 .

[0050] The protrusion 34 is configured to have a hemispherical shape, and a plurality of third balls 35 are rotatably mounted on the outer wall of the third abutting block 33 .

[0051] The outer wall of the protective bracket main body 1 is fixedly connected with a Velcro 2, the outer wall of the protective bracket main body 1 is provided with a plurality of evenly distributed air holes 3, and the outer wall of the protective bracket main body 1 is fixedly connected with a memory foam 7.

[0052] In this embodiment: continue to start the electric push rod 9, when the first ball 13 slides to the end of the inner wall of the spiral groove 16, the first guide rod 10, the fixing frame 11 and the second guide rod 12 will move the rotating cylinder 15 as a whole, and the movement of the rotating cylinder 15 will move the movable plate 14 synchronously. The movable plate 14 moves in the direction close to the second fixed frame 19, and during the movement, it follows the guidance of the first guide rod 17 and compresses the first return spring 18. It should be noted that when the first ball 13 has not slid to the end of the inner wall of the spiral groove 16, the force applied by the first ball 13 to the rotating cylinder 15 is not enough to cause the rotating cylinder 15 to move horizontally, and when it slides to the end of the spiral groove 16, the first ball 13 will hit the inner wall of the end of the spiral groove 16, which will cause the rotating cylinder 15 to move under force.

[0053] As the first ball 13 slides to the end of the inner wall of the spiral groove 16, the first guide rod 10 also moves with the first interference block 39 to interfere with the outer wall of the protrusion 34. As the first guide rod 10 continues to move, the first interference surface 27 at the end of the first interference block 39 interferes with the outer wall of the protrusion 34. The interference causes the protrusion 34 to move forward with the third interference block 33 under force, and when the third interference block 33 moves forward, it moves synchronously with the fourth guide rod 32. When the fourth guide rod 32 moves, it is guided by the inclined third guide rod 30. Therefore, the fourth guide rod 32 will first move with the third interference block 33 toward a position close to the drainage tube 6, as shown in the attached figure. Figure 10 As shown in the figure, after the third resistance block 33 is squeezed with the outer wall of the drainage tube 6, it squeezes the drainage tube 6 in the middle together with the corresponding second resistance block 28, and the blocked thrombus in the drainage tube 6 is deformed or crushed by squeezing. The squeezing causes the corresponding position of the drainage tube 6 to deform, causing the internal fluid to start flowing.

[0054] Under the action of the inclined third guide rod 30, as the third resistance block 33 continues to move, after squeezing and deforming the drainage tube 6, the third resistance block 33 will continue to move obliquely along the third guide rod 30 for a distance. The multiple third balls 35 on the outer wall of the third resistance block 33 will reduce the sliding friction between the third resistance block 33 and the outer wall of the drainage tube 6, so that the third resistance block 33 moves smoothly. At this time, the third resistance block 33 not only squeezes the outer wall of the drainage tube 6, but also slides and smoothes the deformed drainage tube 6 while squeezing the drainage tube 6, so that the thrombus blockage at the corresponding position of the drainage tube 6 is smoothed in the direction of the drainage tube 6 to transport the urine bag after being squeezed and deformed, pushing the thrombus blockage toward the urine bag.

[0055] It should be noted that, there are multiple second chutes 29, and the inclined directions of every two second chutes 29 are opposite to each other, as shown in the attached figure. Figure 10 As shown in , such an arrangement makes it possible for some stubborn thrombus blockages to still be unable to move after being squeezed, and the two adjacent third resistance blocks 33 will squeeze and push the drainage tube 6 in opposite directions, causing the drainage tube 6 in this section to be pushed and deformed from both sides toward the middle position, further promoting the circulation of thrombus in the drainage tube 6. This process can be achieved by reciprocatingly starting the electric push rod 9 to move its output end left and right to achieve the first resistance block 39 reciprocatingly resisting multiple protrusions 34.

[0056] It should be noted that, based on the two-way backflow blocking in Example 1, further cleaning measures are implemented for the blood clots in the drainage tube 6, and the effect of squeezing and crushing is achieved during the cleaning process. Subsequently, the operation of pressing, smoothing and pushing can push the blood clots toward the urine bag. In this process, the two adjacent third resistance blocks 33 will squeeze back and forth in opposite directions while smoothing and pushing the drainage tube to deform it, pressing and squeezing the blood clots therein relative to the left and right until they are deformed to the extent that they can flow.
