Description

Technical Field

[0001] This invention relates to the field of silicone stent technology in respiratory medicine, specifically a silicone stent with radioactive particles for use in respiratory medicine. Background Technology

[0002] Silicone stents are airway stents made of silicone rubber, widely used in respiratory medicine, primarily for treating airway stenosis, and can also be used to treat tracheoesophageal fistula, as exemplified by a silicone stent with publication number CN210990955U. One such silicone stent includes a stent body and a buffer tube. The stent body is a tubular structure open at both ends, with multiple flanges spaced apart on its outer wall. The buffer tube is also a tubular structure open at both ends, with one end sealed to one end of the stent body, allowing communication between them. The outer diameter of the buffer tube near the stent body is the same as the outer diameter of the stent body near the buffer tube, while the outer diameter of the buffer tube near the stent body is larger than the outer diameter of the end of the buffer tube furthest from the tubular body. Furthermore, the outer diameter of the buffer tube gradually decreases from the end near the stent body to the end furthest from the tubular body. This type of silicone stent causes less irritation to the tracheal wall and can prevent excessive granulation tissue growth. For example, a silicone airway stent with publication number CN217593431U includes a body, the outer wall of which is provided with several pin teeth; the pin teeth are truncated cones with concave top surfaces; the body comprises an inner layer, a middle layer, and an outer layer from the inside out. The body is a circular tubular structure with a certain thickness, which provides mechanical support for narrow airways and increases the effective ventilation area of ​​the airway. The antibacterial and hydrophilic layer has antibacterial and hydrophilic functions, facilitating the drainage of airway secretions and preventing infection; the top surface of the pin teeth is designed as a concave inner spherical structure, which can create a suction cup-like fixation effect between the pin teeth and the airway, improving the fixation effect between the stent and the airway, preventing airway stent displacement, and ultimately improving the therapeutic effect. Silicone stents are mainly available in two types: straight and Y-shaped. They can be used for different diseases. However, different situations may arise during the work process, requiring staff to use different types of silicone stents. The device in the aforementioned application does not have the function of quick docking and deformation, which limits the scope of use of the device and makes its use more restrictive.

[0003] To address the aforementioned issues, there is an urgent need for innovative designs based on existing silicone stents. Summary of the Invention

[0004] The purpose of this invention is to provide a silicone stent with radioactive particles for respiratory medicine, in order to solve the problems mentioned in the background art, which are that the device does not have the function of rapid docking and deformation, resulting in a small range of use and great limitations.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a silicone stent with radioactive particles for respiratory medicine, comprising a main stent and a first baffle, wherein a connecting shaft is rotatably disposed inside the main stent, and a through hole is formed on the surface of the main stent, and the end of the connecting shaft is located inside the through hole, and the connecting shaft is symmetrically distributed about the center of the through hole; The first baffle is fixedly installed on the surface of the upper connecting shaft, and the second baffle is fixedly installed on the surface of the lower connecting shaft; A silicone scaffold with radioactive particles for respiratory use also includes: The connecting bracket has a sliding locking block inside, and the end of the connecting bracket is inclined. Both the surface of the connecting bracket and the surface of the main bracket are fixedly installed with protrusions. The slider is fixedly installed on the left and right sides of the card block.

[0006] Preferably, the first baffle is symmetrically distributed about the center of the main support, and a deep groove is provided at the end of the first baffle. A positioning rod is slidably arranged inside the second baffle. Initially, the end of the positioning rod is located inside the deep groove, so the first baffle and the second baffle are in a locked state. At this time, the first baffle and the second baffle are in a vertical state, and the first baffle and the second baffle block the through hole, so that the main support can be used normally.

[0007] Preferably, the positioning rod corresponds one-to-one with the deep groove, and a lever is fixedly installed on the surface of the positioning rod. The end of the lever is located inside the second baffle. When it is necessary to open the through hole, the lever needs to be pulled first, and the lever drives the positioning rod to move to the outside of the deep groove.

[0008] Preferably, the surface of the positioning rod is in contact with the inner wall of the second baffle, and a first spring that plays an elastic reset role is fixedly installed on the lower surface of the positioning rod, and the other side of the first spring is fixedly connected to the inner wall of the second baffle. Initially, under the action of the first spring, the end of the positioning rod is stably located in the deep groove. When the lever is pulled, the lever moves the positioning rod out of the deep groove, and at this time the first spring is squeezed.

[0009] Preferably, a long pin is fixedly installed on the inner wall of the main bracket, and the long pin is located inside the first baffle and the second baffle, and the rotation angle of the connecting shaft is 0°~90°.

[0010] Preferably, a torsion spring that provides elastic reset is fixedly installed on the surface of the connecting shaft, and the other side of the torsion spring is fixedly connected to the inner wall of the main bracket. Initially, the torsion spring is in a compressed state. After the end of the positioning rod moves out of the deep groove, the connecting shaft rotates under the action of the torsion spring, eventually making the first baffle and the second baffle both in a horizontal state. At this time, the connecting bracket can be connected, thereby expanding the overall applicability of the device.

[0011] Preferably, the connecting bracket has positioning grooves on both the upper and lower sides, and positioning blocks are fixedly installed on the surface of the main bracket, with each positioning block corresponding to a positioning groove. When installing the connecting bracket, the positioning blocks are made to enter the positioning grooves.

[0012] Preferably, the slider is slidably disposed inside the connecting bracket, and the connecting bracket has a groove corresponding to the slider. During the installation of the connecting bracket, the inclined surface of the locking block is pushed by the first baffle or the second baffle. At this time, the locking block drives the slider to slide inside the groove. The slider and the groove limit the movement distance of the locking block and ensure stability.

[0013] Preferably, the surface of the card block is inclined, and a second spring that plays an elastic reset role is fixedly installed on the surface of the slider. The other side of the second spring is fixedly connected to the inner wall of the connecting bracket. When the card block drives the slider to slide inside the groove, the second spring is compressed.

[0014] Preferably, the upper surface of the first baffle and the lower surface of the second baffle are provided with slots corresponding to the locking block. When the surface of the connecting bracket contacts the outer wall of the main bracket, the locking block and the slot are in the same vertical direction. At this time, the locking block enters the inside of the slot under the action of the second spring, that is, the connecting bracket has been installed on the main bracket. This expands the overall application range of the device and reduces its limitations.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This silicone scaffold with radioactive particles for respiratory use adopts a novel structural design, the specific details of which are as follows: (1) The silicone stent with radioactive particles used in the respiratory department initially has the end of the positioning rod located inside the deep groove, and the first baffle and the second baffle are in a locked state. At this time, the first baffle and the second baffle are both in a vertical state, that is, the first baffle and the second baffle block the through hole, so that the main stent can be used normally. (2) When the main stent is in use, the first and second baffles are in a vertical position, which facilitates the normal use of the main stent. When it is necessary to connect the stent, pull the lever to move the end of the positioning rod out of the deep groove. At this time, the connecting shaft rotates under the action of the torsion spring. Finally, the first and second baffles are in a horizontal position, and the stent can be connected. The positioning block enters the positioning groove, and then the locking block enters the locking groove, which expands the overall application range of the device. (3) The silicone stent with radioactive particles used in the respiratory department can be removed by pulling the locking block when the connecting stent needs to be removed. This will cause the end of the locking block to move out of the slot. At this time, the connecting stent is not in a locked state with the first baffle and the second baffle, so the connecting stent can be pulled out directly. The disassembly and assembly process is relatively simple, which expands the overall applicability of the device and reduces its limitations. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-8 The present invention provides a technical solution: a silicone stent with radioactive particles for respiratory medicine, comprising a main stent 1 and a first baffle 3. A connecting shaft 2 is rotatably arranged inside the main stent 1, and a through hole 20 is opened on the surface of the main stent 1. The end of the connecting shaft 2 is located inside the through hole 20, and the connecting shaft 2 is symmetrically distributed about the center of the through hole 20. The first baffle 3 is fixedly installed on the surface of the upper connecting shaft 2, and a second baffle 5 is fixedly installed on the surface of the lower connecting shaft 2. A silicone scaffold with radioactive particles for respiratory use also includes: The connecting bracket 11 has a sliding locking block 14 inside, and the end of the connecting bracket 11 is inclined. Both the surface of the connecting bracket 11 and the surface of the main bracket 1 are fixedly installed with protrusions 19. The slider 15 is fixedly installed on the left and right sides of the card block 14. The first baffle 3 is symmetrically distributed about the center of the main bracket 1, and the end of the first baffle 3 is provided with a deep groove 4. The second baffle 5 is slidably provided with a positioning rod 6, which corresponds one-to-one with the deep groove 4. The surface of the positioning rod 6 is fixedly installed with a toggle block 7, and the end of the toggle block 7 is located inside the second baffle 5.

[0020] Initially, the end of the positioning rod 6 is located inside the deep groove 4, and the first baffle 3 and the second baffle 5 are engaged. At this time, the first baffle 3 and the second baffle 5 are both in a vertical state, that is, the first baffle 3 and the second baffle 5 block the through hole 20, so that the main bracket 1 can be used normally.

[0021] The surface of the positioning rod 6 is in contact with the inner wall of the second baffle 5, and a first spring 9 that plays an elastic reset role is fixedly installed on the lower surface of the positioning rod 6. The other side of the first spring 9 is fixedly connected to the inner wall of the second baffle 5. A long pin 8 is fixedly installed on the inner wall of the main bracket 1, and the long pin 8 is located inside the first baffle 3 and the second baffle 5. The rotation angle of the connecting shaft 2 is 0°~90°.

[0022] A torsion spring 10, which plays an elastic reset role, is fixedly installed on the surface of the connecting shaft 2, and the other side of the torsion spring 10 is fixedly connected to the inner wall of the main bracket 1. The torsion spring 10 is initially in a compressed state.

[0023] When the connecting bracket 11 needs to be docked, pull the lever 7, causing the end of the positioning rod 6 to move out of the deep groove 4. At this time, the connecting shaft 2 rotates under the action of the torsion spring 10, and finally the first baffle 3 and the second baffle 5 are in a horizontal state. At this time, the connecting bracket 11 can be docked, and the positioning block 13 enters the positioning groove 12. During the installation of the connecting bracket 11, the inclined surface of the locking block 14 will be pushed by the first baffle 3 or the second baffle 5. At this time, the locking block 14 drives the slider 15 to slide inside the slide groove 16. The slider 15 and the slide groove 16 limit the movement distance of the locking block 14 and ensure stability. At this time, the second spring 17 is squeezed. When the surface of the connecting bracket 11 contacts the outer wall of the main bracket 1, the locking block 14 and the locking groove 18 are in the same vertical direction. At this time, the locking block 14 enters the interior of the locking groove 18 under the action of the second spring 17, that is, the connecting bracket 11 has been installed on the main bracket 1. This expands the overall application range of the device and reduces its limitations.

[0024] The upper and lower sides of the connecting bracket 11 are provided with positioning grooves 12. The surface of the main bracket 1 is fixedly installed with positioning blocks 13, and the positioning blocks 13 correspond one-to-one with the positioning grooves 12. The slider 15 is slidably disposed inside the connecting bracket 11, and the inside of the connecting bracket 11 is provided with sliding grooves 16 that correspond one-to-one with the slider 15.

[0025] The surface of the locking block 14 is inclined, and a second spring 17 that plays an elastic reset role is fixedly installed on the surface of the slider 15. The other side of the second spring 17 is fixedly connected to the inner wall of the connecting bracket 11. The upper surface of the first baffle 3 and the lower surface of the second baffle 5 are both provided with a slot 18 corresponding to the locking block 14.

[0026] When it is necessary to remove the connecting bracket 11, simply pull the locking block 14 so that the end of the locking block 14 moves out of the locking slot 18. At this time, the connecting bracket 11 is not in a locked state with the first baffle 3 and the second baffle 5, so the connecting bracket 11 can be pulled out directly. The disassembly and assembly process is relatively simple.
