Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic ablation equipment, and in particular to an ultrasonic ablation equipment for myocardial hypertrophy and fibrosis caused by heart failure. Background Art

[0002] Hypertrophic cardiomyopathy is a myocardial disease of unknown cause, characterized by asymmetric hypertrophy of the ventricular wall, often invading the ventricular septum, shrinking of the ventricular cavity, obstruction of left ventricular blood filling, and decreased left ventricular diastolic compliance. Hypertrophic cardiomyopathy is divided into obstructive and non-obstructive according to the presence or absence of obstruction in the left ventricular outflow tract, which may be related to genetics. Hypertrophic cardiomyopathy carries a risk of sudden death and is one of the causes of sudden death during exercise.

[0003] Patients with heart failure often have ventricular hypertrophy, which starts as concentric hypertrophy and gradually develops into eccentric hypertrophy. Generally, ultrasonic ablation equipment is used for treatment. The contact block of the equipment is moved near the patient's ventricle, and then the center of the ventricular wall is located, and high-intensity focused treatment is performed on the peripheral hypertrophy. During the treatment process of existing ultrasonic ablation equipment, the ventricular wall (divided into multiple adjacent areas) is focused one by one. After the focusing treatment of the local position is completed, the adjacent local position is then treated, rather than a reciprocating cycle from the outside to the inside along the ventricular wall. The existing method cannot guarantee the overall contraction of the ventricular wall, and cannot make the focusing progress of the entire ventricular wall consistent. Instead of focusing on an area for a long time, it is easy to cause the degree of contraction of the area to be too different from the position of the adjacent area, resulting in excessive contraction and affecting the organ.

[0004] To this end, we propose an ultrasonic ablation device for myocardial hypertrophy and fibrosis in heart failure. Summary of the invention

[0011] Preferably, a limiting sleeve that is slidably matched with the tooth plate is fixedly connected to the rotating plate to ensure that the tooth plate can smoothly mesh with the gear and move.

[0012] Preferably, the transmission lines at both ends of the hinged rod are in a relaxed state to avoid poor contact of the transmission lines due to rotation and pulling.

[0013] Preferably, the length of the slide plate along the direction of the sliding groove is greater than the cross-sectional length of the limiting frame.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention uses a spiral limiting frame and a rotating plate to drive the focuser to rotate spirally along the limiting frame, thereby performing spiral focusing treatment along the ventricle from the outside to the inside to ensure that the overall contraction degree of the hypertrophic ventricle is adapted to each other, thereby avoiding excessive contraction of a local position and affecting the organ.

[0021] The transmission line 3 is arranged along the moving arm to connect the ultrasonic driver 24 with the focuser 2. The moving arm positions the contact block 1 to the ventricle after multi-degree-of-freedom adjustment. The ultrasonic driver 24 converts the radio waves into special high-frequency radio waves and sends them to the focuser 2, which are then emitted to the tissue of the ventricle through the focuser 2.

[0022] See also Figure 6-Figure 8 The movable component 5 shown in the figure includes two rotating plates 6 with a gap distribution. The two rotating plates 6 are connected and fixed at both ends.

A fixing rod 9 is fixedly connected inside the contact block 1. A motor 10 is fixedly connected to the bottom end of the fixing rod 9. The output shaft of the motor 10 is connected and fixed to the two rotating plates 6 at the same time. The length of the slide plate 8 along the sliding groove 7 is greater than the cross-sectional length of the limit frame 4.

[0023] See also Figure 4-Figure 5 The winding assembly 11 shown in the figure includes a connecting rod 12 connected and fixed to the fixed rod 9, the connecting rod 12 is connected and fixed to the transmission line 3, a rotating plate 13 is movably fitted on the fixed rod 9, a limiting ring 14 sleeved on the transmission line 3 is fixedly connected to the end of the rotating plate 13, and a matching assembly 15 is provided on the rotating plate 13.

[0024] In this embodiment, the motor 10 rotates to drive the rotating plate 6 to rotate. Under the action of the spiral limiting frame 4, the rotating rotating plate 6 causes the sliding plate 8 to move along the sliding groove 7, thereby driving the focusing device 2 to make a spiral rotation along the limiting frame 4, thereby performing spiral focusing treatment along the ventricle from the outside to the inside, so as to ensure that the overall contraction degree of the hypertrophic ventricle is mutually adapted, thereby avoiding excessive contraction of a local position and affecting the organ; When the rotating plate 6 rotates, the transmission line 3 is driven to wind around the fixed rod 9 under the action of the connecting rod 12, and the rotating plate 13 is rotated and moved up and down along the fixed rod 9 under the action of the matching component 15, so that the sleeved limiting ring 14 drives the transmission line 3 to cooperate with the supporting component 20 to prevent the transmission line 3 from being disturbed by contact during the rotation of the rotating plate 6; The motor 10 can rotate forward and reversely. When the focuser 2 rotates from the inside to the outside, the motor 10 is turned over to turn the focuser 2 inside out. Example

A limiting sleeve 23 slidingly matched with the toothed plate 19 is fixedly connected to the rotating plate 6.

[0026] In this embodiment, when the slide plate 8 moves along the sliding groove 7, it drives the tooth plate 19 to move along the limiting sleeve 23, so that the gear 16 rotates on the rotating plate 6, thereby causing the threaded rod 17 to rotate. Under the limiting action of the rotating plate 13, the threaded sleeve 18 moves up and down without rotating, thereby driving the rotating plate 13 and the limiting ring 14 to move up and down, so that the transmission line 3 is evenly wound on the fixed rod 9. Example

[0027] This embodiment 3 is a further supplement and explanation of the embodiment 2. Figure 8-Figure 9 The support assembly 20 shown in the figure includes two hinged rods 21 that are hinged to each other. The ends of the two hinged rods 21 are hinged to the slide plate 8 and the rotating plate 6 respectively. The hinges of the two hinged rods 21 are rotatably connected with a connecting plate 22 connected to the transmission line 3. The local position of the transmission line 3 is adhered and fixed to one of the hinged rods 21, and the transmission line 3 located at both ends of the hinged rods 21 is in a relaxed state.

[0028] In this embodiment, when the slide plate 8 moves along the sliding groove 7, the two hinged rods 21 adapt to the rotation and cooperate with the transmission line 3 on the connecting plate 22 to rotate, so that the transmission line 3 is straightened, which is more conducive to avoiding the transmission line 3 from being disturbed by contact during the rotation of the rotating plate 6.
