Description

Technical Field

[0001] This application relates to the field of excimer laser thrombolysis device technology, and in particular to a fiber optic catheter self-identification and adjustment system for an excimer laser thrombolysis device. Background Technology

[0002] 308nm excimer laser thrombolysis is a technique that uses an excimer laser with a wavelength of 308nm to ablate thrombi. This technique uses an inert halide as the laser medium and emits high-intensity unidirectional ultraviolet light waves with a wavelength of 308nm. Through photochemical, photothermal, and photomechanical effects, it can uniformly ablate thrombi or plaques, thereby effectively reducing the volume of thrombi or plaques. Unlike previous long-wavelength thermal lasers, the short-wavelength ultraviolet cold laser used by the excimer laser has a shallower ablation depth, releases less heat, and causes less unnecessary tissue damage, effectively ensuring the safety of the procedure and making its application in coronary arteries more promising. However, the existing 308nm excimer laser thrombosis ablation equipment is difficult to shape and form the laser spot, and it cannot accurately identify various types of fiber optic connectors. As a result, a lot of time needs to be spent manually adjusting the size and shape of the laser spot before the operation, which is inefficient and difficult. This leads to poor efficiency and safety of the equipment, making it difficult to promote and use on a large scale, and has great limitations.

[0003] Therefore, there is an urgent need for an automatic fiber optic catheter identification system for excimer laser thrombosis ablation devices to address the shortcomings of existing excimer laser thrombosis ablation devices in practical use. Summary of the Invention

[0004] This application proposes a fiber optic catheter self-identification and adjustment system for an excimer laser thrombolysis device. This system can automatically identify and connect to different types of fiber optic connectors, and automatically adjust the light spot to be suitable for each connector. It offers advantages such as high stability and reliability. This addresses the problem of existing 308nm excimer laser thrombolysis devices having difficulty and uniformity in shaping the light spot, making it impossible to accurately identify various fiber optic connector types. This results in significant time spent manually adjusting the light spot size and shape before surgery, leading to low efficiency and high difficulty, and ultimately, poor efficiency and safety, hindering large-scale deployment.

[0005] To achieve the above objectives, this application adopts the following technical solution: a fiber optic catheter self-identification and adjustment system for an excimer laser thrombolysis device, comprising a mounting block fixedly installed in the excimer laser thrombolysis device by bolts, and a set of connecting rods installed at each of the four corners of the mounting block. The tops of the four sets of connecting rods extend upwards and are fixedly mounted with fiber optic connection modules. Each fiber optic connection module consists of a connection socket and an encoding board. The fiber optic catheter is then connected to the fiber optic connection module via the connection socket, and the encoding board identifies the model of the connected fiber optic catheter and generates encoded information which is transmitted to the processor. A beam focusing module is fixedly installed in the middle of the four sets of connecting rods, above the mounting block. The beam focusing module has a beam focusing mechanism inside. A beam reflection module is fixedly installed at the bottom of the four sets of connecting rods and below the mounting clamp. The beam reflection module contains a beam reflecting lens. An aperture assembly is fixedly installed on the outer surface of the two sets of connecting rods on the right side. The aperture assembly is electrically connected to the processor and adjusts the rotation angle of the aperture assembly according to the coded information fed back by the processor. This adjusts the outer diameter of the incoming beam. Under the action of the beam focusing module and the beam reflection module, the incoming beam is reflected and focused into a spot of fixed size and shape to fit the fiber optic conduit connected to the fiber optic connection module. No manual intervention is required for debugging, which effectively improves the efficiency and safety of the device and greatly benefits medical staff in the operation of thrombolysis.

[0006] Furthermore, the aperture assembly includes a mounting plate fixedly mounted on the connecting rod, and a drive motor fixedly mounted at the bottom end of the mounting plate. A mounting bracket is fixedly mounted on the outer surface of the connecting rod. A light-shielding sleeve is movably sleeved inside the mounting bracket and driven by a reducer and the output shaft of the drive motor. Under the drive of the drive motor, the light-shielding sleeve can rotate. The light-shielding sleeve has a through-hole for adjusting the outer diameter of the light beam. When it is necessary to reduce the outer diameter of the light beam, the light-shielding sleeve and the through-hole on it rotate clockwise under the drive of the drive motor. The tilt of the light-shielding sleeve blocks excess light beam from passing through the through-hole to reduce the outer diameter of the light beam. When it is necessary to increase the outer diameter of the light beam, the light-shielding sleeve and the through-hole on it rotate counterclockwise under the drive of the drive motor and return to the initial position.

[0007] Furthermore, the cross-section of the light-transmitting aperture is designed as an elliptical structure, which effectively increases the effective adjustment range of the outer diameter of the beam when it rotates, making the excimer laser thrombolysis device more widely applicable.

[0008] Furthermore, the upper right and lower left corners of the light-shielding sleeve are each provided with a set of through vents, and the corresponding positions of the mounting bracket are provided with a set of cooling pipes connected to the cooling system. Initially, the vents on the light-shielding sleeve and the cooling pipes on the mounting bracket are offset clockwise. When the light-shielding sleeve rotates clockwise, the vents and cooling pipes overlap and connect with each other, and increase in size to increase the flow of coolant. This prevents excess light beams from shining on the upper right and lower left corners of the light-shielding sleeve when it rotates clockwise, thus preventing the temperature at those positions from rising rapidly. This effectively improves the stability and reliability of the excimer laser thrombolysis device during operation.

[0009] Furthermore, a sensing block is provided on the top of the outer surface of the light-shielding sleeve, and a conductive block that cooperates with the sensing block is provided on the top of the outer surface of the mounting bracket. The sensing block, the conductive block and the cooling system form a feedback connection. When the light-shielding sleeve rotates clockwise, the overlap between the sensing block and the conductive block increases to improve the pumping flow of the cooling system for the coolant, further enhancing its cooling effect on the upper right and lower left corners of the light-shielding sleeve and preventing the light-shielding sleeve from experiencing a rapid temperature rise.

[0010] Furthermore, a light-shielding component is provided on the right end face of the mounting clamp and above the aperture assembly. When the excimer laser thrombolysis device is not in operation, the light-shielding component is triggered to move the light-shielding plate on it downward to block the aperture assembly, thereby effectively preventing the excimer laser thrombolysis device from being falsely triggered.

[0011] The beneficial effects of this invention are as follows: 1. The fiber optic catheter self-identification and adjustment system of the excimer laser thrombolysis instrument provided in this application can adjust the outer diameter of the incoming light beam by setting the mounting clamp and its structure. Under the action of the beam focusing module and the beam reflection module, the incoming light beam is reflected and focused into a light spot of fixed size and shape to adapt to the fiber optic catheter connected to the fiber optic connection module. No manual intervention is required for debugging, which effectively improves the efficiency and safety of the equipment and greatly benefits medical staff in the operation of thrombolysis.

[0012] 2. The fiber optic catheter self-identification and adjustment system of the excimer laser thrombolysis instrument provided in this application, regarding the setting of the aperture assembly and its structure, when it is necessary to reduce the outer diameter of the beam, the light-shielding sleeve and the light-transmitting hole on it are driven by the drive motor to rotate clockwise, thereby using the deflection of the light-shielding sleeve to block excess beam from passing through the light-transmitting hole to achieve the purpose of reducing the outer diameter of the beam. When it is necessary to increase the outer diameter of the beam, the light-shielding sleeve and the light-transmitting hole on it are driven by the drive motor to rotate counterclockwise and return to the initial position. The operation is simple and convenient.

[0013] 3. The fiber optic catheter self-identification and adjustment system of the excimer laser thrombolysis device provided in this application can effectively prevent the excess light beam from shining on the upper right and lower left corners of the light shielding plate when the light shielding plate rotates clockwise, thus preventing the temperature at those positions from rising rapidly. This effectively improves the stability and reliability of the excimer laser thrombolysis device during operation. Attached Figure Description

The fiber optic connection modules 3 consist of a connection socket and an encoding board. The fiber optic catheter is connected to the fiber optic connection modules 3 through the connection socket. The encoding board identifies the model of the connected fiber optic catheter and generates encoding information which is transmitted to the processor. A beam focusing module 4 is fixedly installed in the middle of the four sets of connecting rods 2 and above the mounting block 1. The beam focusing module 4 has a beam focusing lens inside. A beam reflection module 5 is fixedly installed at the bottom of the four sets of connecting rods 2 and below the mounting block 1. The beam reflection module 5 has a beam reflecting lens inside. An aperture assembly 6 is fixedly installed on the outer surface of the two sets of connecting rods 2 on the right side. The aperture assembly 6 is electrically connected to the processor and adjusts the rotation angle of the aperture assembly 6 according to the encoding information fed back by the processor. Furthermore, the outer diameter of the incoming beam can be adjusted, and under the action of the beam focusing module 4 and the beam reflection module 5, the incoming beam is reflected and focused into a spot of fixed size and shape to adapt to the fiber optic conduit connected to the fiber optic connection module 3. No manual intervention is required for debugging, which effectively improves the efficiency and safety of the equipment and greatly benefits medical staff in the operation of thrombolysis.

[0018] like Figure 2 , Figure 3 As shown, in this technical solution, the aperture assembly 6 includes a mounting plate 8 fixedly mounted on the connecting rod 2, and a drive motor 9 fixedly mounted at the bottom end of the mounting plate 8. A mounting bracket 10 is fixedly mounted on the outer surface of the connecting rod 2. A light-shielding sleeve 11 is movably sleeved inside the mounting bracket 10 and is driven by a reducer and the output shaft of the drive motor 9. Under the drive of the drive motor 9, the light-shielding sleeve 11 can rotate. The light-shielding sleeve 11 has a light-transmitting hole 12 that runs through it from left to right for adjusting the outer diameter of the light beam. When it is necessary to reduce the outer diameter of the light beam, under the drive of the drive motor 9, the light-shielding sleeve 11 and the light-transmitting hole 12 on it rotate clockwise. The tilt of the light-shielding sleeve 11 blocks excess light beam from passing through the light-transmitting hole 12 to achieve the purpose of reducing the outer diameter of the light beam. When it is necessary to increase the outer diameter of the light beam, under the drive of the drive motor 9, the light-shielding sleeve 11 and the light-transmitting hole 12 on it rotate counterclockwise and return to the initial position.

[0019] like Figure 3As shown, in this technical solution, the cross-section of the light-transmitting hole 12 is set as an elliptical structure, which effectively increases the effective adjustment range of the outer diameter of the beam when it rotates, making the excimer laser thrombolysis device more widely applicable.

Initially, the positions of the vent holes 13 on the light-shielding sleeve 11 and the cooling pipes on the mounting bracket 10 are offset clockwise. When the light-shielding sleeve 11 rotates clockwise, the vent holes 13 and the cooling pipes overlap and connect with each other and increase in size to increase the flow of coolant. This prevents excess light beams from illuminating the upper right and lower left corners of the light-shielding sleeve 11 when it rotates clockwise, thus preventing the temperature at those positions from rising rapidly. This effectively improves the stability and reliability of the excimer laser thrombolysis device during operation.

[0021] like Figure 3 , Figure 5 As shown, in this technical solution, a sensing block 14 is provided on the top of the outer surface of the light-shielding sleeve 11, and a conductive block 15 that cooperates with the sensing block 14 is provided on the top of the outer surface of the mounting bracket 10. The sensing block 14, the conductive block 15 and the cooling system form a feedback connection. When the light-shielding sleeve 11 rotates clockwise, the overlap between the sensing block 14 and the conductive block 15 increases to improve the pumping flow of the cooling system for the coolant, further improving its cooling effect on the upper right and lower left corners of the light-shielding sleeve 11, and preventing the light-shielding sleeve 11 from experiencing a rapid temperature rise.

[0022] like Figure 1 As shown, in this technical solution, a light-shielding component 7 is provided on the right end face of the mounting clamp 1 and above the aperture assembly 6. When the excimer laser thrombolysis device is not in operation, the light-shielding component 7 is triggered to move the light-shielding plate on it downward to block the aperture assembly 6, thereby effectively preventing the excimer laser thrombolysis device from being falsely triggered.
