Description

Technical Field

[0001] The invention relates to the technical field of cardiovascular surgical instruments and equipment, in particular to an anchored microcatheter for accurately puncturing completely occluded lesions in a coronary cavity. Background Art

[0002] Some existing rotating coronary microcatheters often find it difficult to provide sufficient stability in complex lesion areas, especially when facing completely occluded lesions. This instability may cause the catheter or guidewire to move during the operation, thereby affecting the accuracy of puncture and the surgical effect. This movement not only increases the risk of the operation, but may also prolong the operation time and cause unnecessary harm to the patient. In addition, the existing coronary microcatheters lack real-time image transmission function, and the physician cannot intuitively observe the specific situation of the lesion site during the operation. This "blind operation" increases the difficulty and uncertainty of the operation. The physician can only rely on experience and feel to operate, which undoubtedly increases the risk of the operation.

The middle reinforcing layer 102 is made of woven metal wire. The ventilation tube 5 can supply air to the inflation end 8. The inflation end 8 can expand the inflation balloon 9 and firmly connect it to the blood vessel wall, thereby anchoring the inner guide wire 4 and the puncture end 12 connected to its side. The balloon fixing ring tube 6 is made of medical rubber material.

[0037] The above scheme is adopted: the inner layer 103 is made of lubricating material to facilitate the sliding of the inner guide wire 4; the middle reinforcement layer 102 is woven with metal wire to enhance the strength and toughness of the catheter. The connection between the ventilation tube 5 and the inflation end 8 ensures the accurate inflation of the inflation balloon 9, thereby achieving stable anchoring of the inner guide wire 4 and the puncture end 12.

[0038] The microprobe 11 can help doctors observe the condition of vascular lesions. Its visual image is transmitted to the data collection device 14 through the first data line 13, and then transmitted to the display screen 18 through the second data line 19. The display screen 18 can be rotated by the rotating seat 16 to facilitate the doctor's observation.

[0039] By adopting the above scheme, the microprobe 11 can transmit the visual image of the vascular lesion in real time, providing the physician with an intuitive and accurate surgical field of view, which helps the physician to accurately judge the lesion condition and formulate corresponding surgical strategies.

[0040] The inflation device 20 transmits or extracts gas to the inflation control end 22 through the inflation hose 21. The inflation control end 22 is provided with a switch button, which is connected to the ventilation pipe 5 at the bottom. The inflation and deflation of the inflation balloon 9 can be controlled by the inflation control end 22.

[0043] The above solution is adopted: the initial disinfection of the liquid disinfection box 24 is combined with the ultraviolet disinfection of the ultraviolet disinfection box 23, which ensures the sterility of the puncture end 12 before the operation and reduces the risk of postoperative infection.

[0044] The working principle of the present invention is as follows: first, the microcatheter 1 is operated by a physician through the handle 3 to enter the coronary cavity, and the handle connecting end 2 is fixedly connected to the microcatheter 1 and the handle 3 to ensure operational stability. An inner guide wire 4 is arranged inside the microcatheter 1, and a ventilation tube 5 is arranged inside the inner guide wire 4 to provide a channel for subsequent balloon inflation. A microprobe 11 is arranged on the side of the inner guide wire 4, which can transmit the visual image of the vascular lesion to the data collection device 14 in real time, and then transmit it to the display screen 18 through the second data line 19. The display screen 18 can be rotated to provide an optimal observation angle, so that the physician can accurately judge the lesion condition. When the microcatheter 1 reaches the completely occluded lesion area, the physician obtains real-time images from the data collection device 14 connected by the first data line 13 on the handle connecting end 2, and uses the assistance of the microprobe 11 to accurately locate the occlusion position. At this time, the puncture end 12 on the side of the inner guide wire 4 is ready for puncture operation. In order to stabilize the position of the microcatheter 1 and the inner guide wire 4, The doctor supplies air to the inflation control end 22 through the inflation device 20 and the inflation hose 21. The control end is connected to the ventilation tube 5. The gas enters the inflation balloon 9, causing it to expand and fit tightly against the blood vessel wall, thereby anchoring the microcatheter 1 and the inner guide wire 4 and the puncture end 12 thereon. The annular groove 7 and the inflation end 8 on the balloon fixing ring tube 6 ensure the effective inflation and fixation of the inflatable balloon 9. With the support of a stable anchor, the puncture end 12 accurately punctures and occludes the lesion site. After the puncture is completed, the doctor can continue to observe and evaluate the puncture effect through the display screen 18. In addition, the disinfection system of the present invention also plays an important role. After use, the puncture end 12 is first disinfected through the liquid disinfection box 24. The disinfectant is added through the infusion port 27. The disinfected liquid is discharged into the liquid collection box 26 through the drain pipe 25. Subsequently, the puncture end 12 can be placed in the ultraviolet disinfection box 23, and further ultraviolet disinfection is performed through the disinfection lamp 30 to ensure a sterile environment during use.

[0045] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
