Description
Technical Field
[0001] The utility model relates to the technical field of degradable stents, and more particularly to a device for multi-angle observation of degradable stents. Background Art
[0002] Biodegradable stents are used in medicine, typically to support and restore function in tubes such as blood vessels, the trachea, or the esophagus. Unlike traditional metal stents, biodegradable stents are made of biodegradable materials and gradually degrade and are absorbed by the body over time, eliminating the need for secondary surgical removal. These stents can reduce pain and complications for patients and promote natural tissue repair.
[0003] Biodegradable stents are typically made of biodegradable plastics such as polylactic acid (PLA), polycaprolactone (PCL), and polyhydroxybutyrate (PHB), or biodegradable metals. These materials provide sufficient support and are gradually absorbed and metabolized while supporting tissue recovery, thus avoiding the potential risks of long-term implants.
[0004] In general, the strength of a biodegradable stent should meet therapeutic needs while also taking into account its in vivo degradation characteristics to avoid unnecessary complications and side effects. Therefore, when designing and selecting a biodegradable stent, it is necessary to comprehensively consider the material's mechanical properties, degradation rate, and long-term clinical effects to ensure its safe and effective application in clinical practice.
[0005] When using existing biodegradable stent observation devices, in order to observe the condition of the stent from multiple angles, it is usually necessary to repeatedly install and remove the stent, which can easily cause damage to the stent and lead to unnecessary losses, and is not very practical.
[0006] Therefore, in order to solve the above technical problems, the present application proposes a device for multi-angle observation of degradable stents. Utility Model Content

The effect is that through the setting of the adjusting mechanism, it is convenient to adjust the up and down movement and rotation of the connecting ring, thereby realizing multi-directional and multi-angle observation of the bracket body, facilitating personnel operation, avoiding damage to the bracket body caused by repeated adjustment, and improving practicality.
[0010] Preferably, the side of the connecting ring away from the mounting plate is connected to a connecting rod, the top surface of the other end of the connecting rod is connected to a placement plate, and a number of fixing components are evenly arranged on the upper surface of the placement plate.

[0025] like Figure 1-5 As shown, the utility model provides a device for multi-angle observation of a degradable stent, comprising a base 1, a mounting plate 2 connected to one side above the base 1, and a support column 3 connected to the upper surface of the base 1 adjacent to the mounting plate 2, and an adjustment mechanism 4 provided between the mounting plate 2 and the support column 3;
[0026] The adjustment mechanism 4 includes a connecting shaft 402 that is rotatably connected to the side of the mounting plate 2. The outer end of the connecting shaft 402 is connected to a hand wheel 401. The other end of the connecting shaft 402 passes through the mounting plate 2 and is connected to a bevel gear A403. The upper part of the support column 3 near the mounting plate 2 is connected to a fixed cylinder 406. A threaded rod 405 is rotatably connected in the fixed cylinder 406, and the bottom end of the threaded rod 405 is connected to a bevel gear B404. The bevel gear A403 and the bevel gear B404 are meshed. The threaded rod 4 05 is threadedly connected with a slip ring 410, and the slip ring 410 is slidably connected to the inner wall of the fixed cylinder 406. A limiting groove 409 is provided on the side of the fixed cylinder 406 close to the mounting plate 2. A slider 408 is provided on the outer side of the limiting groove 409, and one end of the slider 408 passes through the limiting groove 409 and is connected to the side of the slip ring 410. The outer side of the fixed cylinder 406 is slidably connected to the connecting ring 407, and the top surface of the slider 408 is fixedly connected to the bottom surface of the connecting ring 407. The effect is that when in use , turn the handwheel 401, the handwheel 401 drives the connecting shaft 402 to rotate, thereby driving the bevel gear A403 to rotate, and the bevel gear A403 drives the bevel gear B404 to rotate, thereby driving the threaded rod 405 to rotate in the fixed cylinder 406. Under the limiting action of the limit groove 409, the rotation of the threaded rod 405 drives the slip ring 410 to move upward, thereby driving the slider 408 to move in the limit groove 409, thereby driving the connecting ring 407 to move outside the fixed cylinder 406. When the slider 408 moves to the top of the limit groove 409, due to the horizontal limit groove 409, under the continuous rotation of the threaded rod 405, the slider 408 rotates horizontally, thereby driving the connecting ring 407 to rotate. Through the provided adjustment mechanism 4, it is convenient to adjust the up and down movement and rotation of the connecting ring 407, thereby realizing multi-directional and multi-angle observation of the bracket body 9, facilitating personnel operation, avoiding damage caused by repeated adjustment of the bracket body 9, and improving practicality.
[0027] The side of the connecting ring 407 away from the mounting plate 2 is connected to a connecting rod 5, and the top surface of the other end of the connecting rod 5 is connected to a placement plate 6. Several fixing components 7 are evenly arranged on the upper surface of the placement plate 6. By setting multiple groups of fixing components 7, simultaneous observation of multiple bracket bodies 9 can be achieved, further improving the practicality of the device.
[0028] The fixing assembly 7 includes a fixing ring 701 fixedly connected to the upper surface of the placement plate 6, and a bolt 702 is threadedly connected to the side of the fixing ring 701, and the other end of the bolt 702 passes through the fixing ring 701 to be connected to the inside with a clamping plate 703, and the curvature of the clamping plate 703 is adapted to the inner circle of the fixing ring 701. When in use, the bracket placement shaft 8 is inserted into the fixing ring 701, and the bolt 702 is rotated, thereby driving the clamping plate 703 to gradually move to the other side of the fixing ring 701, thereby locking and fixing the bracket placement shaft 8. Through the setting of the fixing assembly 7, it is convenient to fix the bracket placement shafts 8 of different sizes, thereby meeting the observation of bracket bodies 9 of different sizes.
[0029] A bracket placement shaft 8 is placed inside the fixing ring 701, and a carrying ring 10 is provided near the bottom of the bracket placement shaft 8. The bracket body 9 is sleeved on the carrying ring 10, which is conducive to supporting the bracket body 9 and preventing the bracket body 9 from sinking into the fixing ring 701, ensuring comprehensive observation of the bracket body 9.
[0030] The limiting groove 409 is L-shaped, and the depth of the limiting groove 409 in the horizontal position is slightly greater than the height of the slider 408. By setting the L-shaped limiting groove 409, it is convenient for the slider 408 to rotate relative to the fixed tube 406 when it moves to the top, thereby realizing the rotation of the connecting ring 407, making it more convenient for personnel to observe the bracket body 9 from multiple angles.
[0031] The top surface of the threaded rod 405 is higher than the top of the limiting groove 409, thereby ensuring that the slip ring 410 will not separate from the threaded rod 405 when moving upward, ensuring normal use of the device.
[0032] Working principle: When in use, first insert multiple bracket placement shafts 8 of different sizes into the fixing ring 701 respectively, rotate the bolt 702, thereby driving the splint 703 to gradually move to the other side of the fixing ring 701, thereby locking and fixing the bracket placement shaft 8, and then sleeve the corresponding bracket body 9 on the bracket placement shaft 8, and then rotate the handwheel 401, the handwheel 401 drives the connecting shaft 402 to rotate, thereby driving the bevel gear A403 to rotate, and the bevel gear A403 drives the bevel gear B404 to rotate, thereby driving the threaded rod 405 to rotate in the fixing cylinder 406, and under the limiting action of the limiting groove 409, the threaded rod 40 5 drives the slip ring 410 to move upward, thereby driving the slider 408 to move in the limiting groove 409, thereby driving the connecting ring 407 to move outside the fixed cylinder 406. When the slider 408 moves to the top of the limiting groove 409, due to the horizontal limiting groove 409, under the continuous rotation of the threaded rod 405, the slider 408 rotates in the horizontal direction, thereby driving the connecting ring 407 to rotate, thereby driving the movement and rotation of the connecting rod 5 and the placement plate 6, thereby realizing multi-directional and multi-angle observation of the bracket body 9, facilitating personnel operation, avoiding damage caused by repeated adjustment of the bracket body 9, and improving practicality.
