Description

Technical Field

[0001] This utility model belongs to the technical field of medical device fixation devices, specifically relating to a rigid bronchoscope fixation device. Background Technology

[0002] Rigid bronchoscopes are a type of modern medical equipment. With the development of medicine, rigid bronchoscopes have also been continuously improved and refined. However, in the last thirty years, with the widespread clinical adoption of flexible fiber optic bronchoscopes, the use of rigid bronchoscopes has significantly decreased. Compared to rigid bronchoscopes, fiber optic bronchoscopes require a certain amount of airway space during operation. While this generally does not cause ventilation dysfunction in healthy adults, it can affect ventilation function and even threaten life in children or those with airway narrowing. Rigid bronchoscopes maintain airway patency and have side ports at the operating end for connection to a ventilator; therefore, they are also called "ventilation bronchoscopes."

[0003] A prior art patent, CN214632372U, describes a rigid bronchoscope fixation device. This patent includes a support, with a magnetic plate fixedly connected to the middle of the bottom of the support, and a fluorocarbon rubber plate fixedly connected to the outer side of the bottom of the support. A retaining sleeve is fixedly connected to the middle of the top of the support, and a ball bearing is engaged on the inner surface of the retaining sleeve. The magnetic plate and fluorocarbon rubber plate ensure the device can be securely placed on ferrous or non-ferrous tabletops. The retaining sleeve and ball bearing allow for adjustment of the fixation position. The device includes a third support rod, a first support plate, an electric telescopic rod, a rotating shaft, and a second support plate. Users can control the extension and retraction of the electric telescopic rod via control buttons, thereby automatically opening and closing the cover. The design incorporates a sleeve, spring, second support rod, and top plate. The rigid bronchoscope is placed on top of the top plate, and closing the cover provides flexible clamping. However, in practical use, its inability to be adjusted adaptably limits its usability. It is difficult to adjust according to the usage scenario, thus reducing the ease of use. Furthermore, fixing the rigid bronchoscope is inconvenient depending on its placement, leading to unstable fixation and difficulty in handling it after fixation, further complicating its practical use.

[0004] Therefore, there is a need for a rigid bronchoscope fixation device to solve the problems of existing technologies, such as the inability to make adaptive adjustments, which reduces its practicality, and the inconvenience of fixing the rigid bronchoscope according to its placement and the difficulty in handling it, resulting in high inconvenience in use.

The pole 2 is fixedly installed on the top of the mounting base 1, the rotating device 3 is located at the top of the pole 2, and an adjustment mechanism 4 is provided on the upper part of the rotating device 3. A fixing mechanism 5 is connected to the adjustment mechanism 4.

[0029] The adjustment mechanism 4 includes a connecting component 41 and a positioning component 42. The connecting component 41 is mounted on the rotating device 3 and connected to the fixing mechanism 5. The positioning component 42 is mounted on the connecting component 41 and connected to the upright 2. The adjustment mechanism 4 is used to adjust the position of the fixing mechanism 5 through the connecting component 41 and the positioning component 42.

[0030] The fixing mechanism 5 includes an installation component 51, a limiting component 52, and a connecting support component 53. The installation component 51 is connected to the connecting component 41. The limiting component 52 is located inside the installation component 51 for limiting and fixing work. The connecting support component 53 is located inside the installation component 51 for adjusting the limiting and fixing process of the limiting component 52.

[0031] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the rotating device 3 includes a connecting seat 301 and a rotating seat 302. The connecting seat 301 is fixedly connected to the top of the upright 2, and the rotating seat 302 is rotatably disposed in the connecting seat 301 and connected to the connecting assembly 41. The rotating device 3 is used to rotate and adjust the adjusting mechanism 4.

[0032] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the connecting assembly 41 includes a support rod 411, a connecting shaft 412, and a limiting rotating shaft 413. The connecting shaft 412 and the limiting rotating shaft 413 are respectively located at the lower end and the upper end of the support rod 411. The support rod 411 is rotatably mounted on the upper part of the rotating seat 302 through the connecting shaft 412, and the support rod 411 is rotatably connected to the fixing mechanism 5 through the limiting rotating shaft 413.

[0033] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth noting that the positioning component 42 includes a sliding sleeve 421, which is slidably fitted onto the upright 2. A fixed shaft 422 is provided on one side of the sliding sleeve 421, and an adjusting column 424 is rotatably connected to the sliding sleeve 421 via the fixed shaft 422. A limit bolt 423 is threadedly connected to the other side of the sliding sleeve 421 and is positioned at the upper limit of the upright 2 via the limit bolt 423. A sliding rod 425 is slidably arranged inside the adjusting column 424. A hinge rod 426 is provided at the upper end of the sliding rod 425. A hinge seat 427 is rotatably connected to the upper part of the sliding rod 425 via the hinge rod 426. The hinge seat 427 is fixedly connected to the support rod 411.

A positioning bolt 429 is threadedly connected to the lower part of the adjusting column 424 near the upper end and is matched with the positioning holes 428. The inner side of the adjusting column 424 is hollow and matches the sliding rod 425.

[0034] In use, by loosening or tightening the limiting bolt 423, the position of the fixing mechanism 5 can be adjusted by rotation and height. At this time, by rotating the rotating seat 302 within the connecting seat 301, the support rod 411 can drive the fixing mechanism 5 to rotate on the upright 2, thereby performing rotation adjustment. Simultaneously, by rotating the support rod 411 up and down, and then by the rotational support of the adjusting column 424 on the sliding sleeve 421, the sliding sleeve 421 slides on the upright 2, thereby adjusting the vertical position of the fixing mechanism 5. At the same time, by loosening the positioning bolt 429, the sliding rod 425 slides within the adjusting column 424, further increasing the adjustment range of the support rod 411, thereby improving the comprehensiveness of the adjustment of the fixing mechanism 5 and enhancing its practicality. Furthermore, by tightening the limiting bolt 423, the adjusted position can be fixed. Simultaneously, by limiting the rotation of the limiting rotating shaft 413, the adjustability of the fixing mechanism 5 can be further improved.

[0035] As can be seen from the above working process, by using the rotating device 3 in conjunction with the adjusting mechanism 4, when fixing the rigid bronchoscope on the fixing mechanism 5, the position of the fixed rigid bronchoscope can be adjusted to adapt to the actual use situation, thereby improving its convenience during use and thus improving the practicality of the device.

[0036] Further as Figure 2 , Figure 4 and Figure 5 As shown, it is worth noting that the mounting component 51 includes a connecting seat 511 and a mounting frame 512. The connecting seat 511 is rotatably mounted on the upper end of the support rod 411 via a limiting pivot 413. The mounting frame 512 is fixedly connected to the right side of the connecting seat 511. The mounting frame 512 is a box-shaped structure with open sides on the right and front and rear sides.

[0037] Further asFigure 2 , Figure 4 and Figure 5 As shown, it is worth noting that the limiting component 52 includes a first movable block 521 and a second movable block 523. The first movable block 521 and the second movable block 523 are symmetrically arranged vertically and movably disposed within the mounting frame 512. The front and rear side surfaces of the first movable block 521 are fixedly connected to a first slider 522, which limits its sliding within the mounting frame 512. The front and rear side surfaces of the second movable block 523 are fixedly connected to a second slider 524, which limits its sliding within the mounting frame 512. Grooves 526 are provided on the upper part of the first movable block 521 and the lower part of the second movable block 523. A flexible pad 525 is provided on the upper part of the second movable block 523. An elastic block 527 is slidably disposed within the first movable block 521 and extends to its bottom. A spring 528 is fixedly installed on the upper part of the elastic block 527 within the first movable block 521. The spring 528 further improves the stability of the rigid bronchoscope fixation.

[0038] Further as Figure 4 , Figure 5 and Figure 6 As shown, it is worth noting that the connecting support assembly 53 includes a limiting groove 531, which is respectively opened on the left side surface of the first movable block 521 and the second movable block 523. An adjusting block 532 is provided at the corresponding position of the limiting groove 531 and slides within the mounting frame 512 through the limiting groove 531. A connecting groove 533 is provided at the bottom end of the adjusting block 532. A first irregular plate 534 is provided inside the connecting groove 533 and is movably disposed in the groove 526 at the bottom of the second movable block 523. A first rotating shaft 535 is fixedly connected to the first irregular plate 534, and a first support block 536 is rotatably connected to the end of the first rotating shaft 535. The first support block 536 is fixedly connected to the bottom of the mounting frame 512. The upper right side of the first irregular plate 534 is fitted with the bottom of the second movable block 523. The top of the adjusting block 532 is provided with the second irregular plate 537 and is located in the top groove 526 of the first movable block 521. The second irregular plate 537 is fixedly connected to the second rotating shaft 538. The end of the second rotating shaft 538 is rotatably connected to the second support block 539. The second support block 539 is fixedly connected to the top of the mounting frame 512. The bottom left side of the second irregular plate 537 is fitted with the top of the adjusting block 532, and the bottom right side of the second irregular plate 537 is fitted with the top of the first movable block 521.

[0039] In use, the rigid bronchoscope is placed between the flexible pad 525 and the elastic block 527. The second movable block 523 slides within the mounting frame 512, pressing against the first irregularly shaped plate 534. This causes the first irregularly shaped plate 534 to rotate on the first support block 536 via the first rotating shaft 535. Consequently, the left end of the first irregularly shaped plate 534 lifts the adjusting block 532, causing the upper end of the adjusting block 532 to lift the second irregularly shaped plate 537. The second irregular plate 537 rotates on the second support block 539 via the second rotating shaft 538. The rotation of the second irregular plate 537 causes the right side of the second irregular plate 537 to push down the first movable block 521, causing the first movable block 521 to slide down within the mounting frame 512. This allows the rigid bronchoscope to be stably positioned by the elastic block 527. At the same time, the rigid bronchoscope can be easily removed, improving the convenience of its use.

[0040] This solution has the following working process: When this device is used, the entire device is installed and positioned using the mounting base 1. At this time, by loosening or tightening the limit bolts 423, the position of the fixing mechanism 5 can be adjusted by rotation and vertical adjustment. Simultaneously, by rotating the rotating seat 302 within the connecting seat 301, the support rod 411 can drive the fixing mechanism 5 to rotate on the upright 2, thus performing rotation adjustment. At the same time, by rotating the support rod 411 vertically, and through the rotational support of the adjusting column 424 on the sliding sleeve 421, the sliding sleeve 421... The support rod 411 slides on the upright 2, thereby adjusting the vertical position of the fixing mechanism 5. Simultaneously, by loosening the positioning bolt 429, the sliding rod 425 slides within the adjusting column 424, further increasing the adjustment range of the support rod 411. This enhances the overall adjustability of the fixing mechanism 5 and improves its practicality. Furthermore, tightening the limiting bolt 423 secures the adjusted position, and the limiting rotation of the limiting shaft 413 further improves the adjustability of the fixing mechanism 5. Then, with the limiting component 52 in place, the rigid bronchoscope is placed between the flexible pad 525 and the elastic block 527. The second movable block 523 slides within the mounting frame 512, causing it to press against the first irregularly shaped plate 534. This causes the first irregularly shaped plate 534 to rotate on the first support block 536 via the first rotating shaft 535. Consequently, the left end of the first irregularly shaped plate 534 lifts the adjusting block 532, which in turn lifts the upper end of the adjusting block 532 against the second irregularly shaped plate 537. 7. The second rotating shaft 538 rotates on the second support block 539. The rotation of the second irregular plate 537 causes the right side of the second irregular plate 537 to push down the first movable block 521, causing the first movable block 521 to slide down within the mounting frame 512. This allows the rigid bronchoscope to be stably limited by the elastic block 527. Furthermore, the spring 528 further improves the stability of the rigid bronchoscope. At the same time, the rigid bronchoscope can be easily removed, improving the convenience of its use.

[0041] In summary: By using the rotating device 3 in conjunction with the adjusting mechanism 4, the position of the rigid bronchoscope can be adjusted to suit the actual usage situation when fixing it to the fixing mechanism 5, thereby improving its convenience during use and enhancing the practicality of the device. The adjusting mechanism 5 facilitates the fixing operation of the rigid bronchoscope, ensuring its stability during fixing and improving its stability during fixing. It also allows for easy handling of the rigid bronchoscope, further enhancing its convenience during actual use.
