Problems solved by technology

Some problems have also been found in the actual application of the existing atrial fibrillation treatment devices. For example, the existing atrial fibrillation treatment devices lack real-time imaging devices that can be developed according to the body orientation requirements during the operation. Doctors hope to observe the guide from other angles It is difficult to process and ablate the site. In addition, the inner wall of the pulmonary vein of some patients is irregular in shape or even has folds. With this physiological structure, the balloon is only attached to the pulmonary vein, so it is difficult to perform ideal ablation on the folds and depressions. Even The fitting force is increased through the front top of the catheter, but due to the softness of the heart and pulmonary veins, the fitting effect is still unsatisfactory, and it is very difficult to stretch the depressions of the folds, which makes the sealing effect unsatisfactory and easily leads to recurrence of patients

Embodiment 1

[0032] Atrial fibrillation treatment devices, such as Figure 1-7 As shown, it includes an operating bed 1, an ultrasound-guided monitoring system, and an ablation mechanism. The ultrasound-guided monitoring system includes a controller, a display 13, a universal adjustment mechanism, and a cardiovascular imaging machine 10 located on the universal adjustment mechanism. The universal adjustment mechanism It includes an arc-shaped guide cylinder 7, an arc-shaped slide rail 6 inserted in the guide cylinder, a first servo motor welded and fixed on the rear side of the middle part of the guide cylinder, a first gear 5 arranged on the output shaft of the first servo motor, The vertical translation mechanism at the upper end of the arc-shaped slide rail and the swing unit at the bottom of the guide cylinder are used to drive the guide cylinder to swing laterally. There is a transmission hole on the back side of the middle part of the cylinder, and a rack structure 39 is provided on ...

Embodiment 2

[0036] Compared with Embodiment 1, the rear end of the operating bed is also provided with a vertical pole, and the scanning mechanism facing the bed body of the operating bed is arranged on the vertical pole. The scanning mechanism is a recognition camera or a millimeter-wave radar or an infrared scanner. The controller and the scanning mechanism Institutional connections. In this embodiment, a recognition camera is used.

[0037] Using the ultrasound-guided monitoring system and the rapid automatic positioning method of the scanning mechanism, including the following steps:

[0038] Step 1. Determine the position and orientation of the cardiovascular imaging machine according to the size, position and motion state of each component of the universal adjustment mechanism;

[0039] Step 2. The recognition camera scans the bed body in advance to form the bed body position coordinates, which are specifically grid-like coordinates, and use this as a reference coordinate. When the...

Embodiment 3

[0043] Different from Example 1, as Figure 8 As shown, the tail of the air pipe is horizontally provided with an inflation and discharge port connected to the inflator, the tail of the air pipe is longitudinally inserted and fixed in a tail air bag, and the tail end of the flexible guide rod is located in the tail air bag. In this way, when the anchor air bag is deflated, air can be filled into the air pipe through the inflation and deflation port first, so as to balance the air pressure on both sides of the baffle, so that the flexible guide rod can push the baffle forward.

[0044] The method for preventing the low temperature from passing through the ventilation tube to the direction of the anchoring airbag: includes the following steps:

[0045] Step 1. After inflating through the ventilation tube, remove the inflation device, and the fixed state of the anchor airbag can still be maintained, and then use the suction device to pump air from the inflation port. The suction ...

Abstract

The invention provides an atrial fibrillation treatment device which comprises an operating bed, an ultrasonic guide monitoring system and an ablation mechanism, and the ultrasonic guide monitoring system comprises a controller, a displayer, a universal adjusting mechanism and an angiocardiography machine arranged on the universal adjusting mechanism. The universal adjusting mechanism comprises an arc-shaped guide cylinder, an arc-shaped sliding rail, a first servo motor, a first gear, a vertical translation mechanism and a swinging unit, and the angiocardiography machine is rotationally arranged at the bottom of the translation mechanism through an intelligent pitching rotating structure. According to the atrial fibrillation treatment device, the universal adjusting mechanism of the ultrasonic guidance monitoring system realizes multi-degree-of-freedom adjustment, and the angiocardiography machine can be easily adjusted to a required direction and a required position.

Description

technical field [0001] The invention relates to the medical field, in particular to an atrial fibrillation treatment device. Background technique [0002] Atrial fibrillation is a kind of heart disease. Atrial fibrillation can lead to reduced cardiac power, decreased blood supply capacity, and weakness of the patient. Atrial fibrillation can also lead to the formation of plaque and thrombus, which is an important cause of death and disability of patients. The treatment of atrial fibrillation is mainly divided into thermal ablation and cold ablation. The existing cryoablation is mainly to place a cryoballoon in the pulmonary vein to block the vein, and use low-temperature nitrogen dioxide to rapidly freeze the surrounding tissue, causing cell necrosis to form a scar Furthermore, ring-shaped electrical isolation is realized. This technology has the advantages of short time consumption, stable abutment, and uniform damage. As a new technology, cryoablation is becoming more and ...
