Problems solved by technology

[0003] Transcatheter interventional therapy is a mechanical interventional therapy to dredge heart valve stenosis or incompetent arteries. The valve is released by balloon expansion or self-expansion to keep the heart artery lumen open and restore blood flow in the artery. To reduce the mortality rate of acute myocardial infarction, the existing transcatheter interventional devices are all hand-held operations. The operator needs to adjust the operation of the device according to the entrance of the guide tube, the position of the patient and the position of the blood vessel, but the hand-held device will affect the operation to a certain extent. At the same time, it increases the risk of surgery, and when the operator needs to determine the best valve release position, it is usually difficult to grasp the direction of the hand-held operation. If the operator blindly delivers the guide tube directly along the direction of the hand-held instrument end, it is likely to cause Serious complications such as valve displacement, cardiac artery rupture and perforation after release may directly lead to surgical failure

Embodiment 1

[0037] A general-purpose stabilizer for interventional instruments for valvular heart disease, such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, it includes a mounting support plate 1, a wedge-shaped connecting frame 21, an 8-shaped slotted frame 22, an arc-shaped connecting frame 23, an arc-shaped opening frame 24, a guide wire transmission assembly 3, a slow rotation assembly 4 and a hand-proof Shaking component 5, two wedge-shaped connecting frames 21 are fixedly installed on the top surface of the support plate 1, and the top of the wedge-shaped connecting frame 21 is fixedly connected with an 8-shaped slotted frame 22, and the right sides of the two 8-shaped slotted frames 22 are fixed together There is an arc-shaped connecting frame 23, the left sides of the two 8-shaped slotted frames 22 are fixedly connected with an arc-shaped holed frame 24, and the two 8-shaped slotted frames 22 are jointly slidably co...

Embodiment 2

[0046] On the basis of Example 1, such as figure 1 , figure 2 Shown, also comprise adjusting screw mandrel 6, on the 8-shaped slotted frame 22, the rotating type is connected with the adjusting screw mandrel 6 that is convenient to rotate and adjust the belt shaft sliding block 31, and the adjusting screw mandrel 6 and the band shaft sliding block 31 are matched by threads way to connect.

[0047] After placing the guide tube, the medical personnel can make the belt shaft sliding block 31 and its upper device move upward or downward by rotating the adjusting screw mandrel 6. When the belt shaft sliding block 31 and its upper device move downward, the slide rail wheel 32 will be in close contact with the guide pipe, thereby increasing the contact area between the slide rail wheels 32 and the guide pipe, so that the two slide rail wheels 32 can efficiently transport the guide pipe when they rotate.

Embodiment 3

[0049] On the basis of Example 1, such as figure 1 , figure 2 , Figure 8 As shown, a guide rail frame 7 is also included, and the guide rail frame 7 is rotatably installed on the arc-shaped opening frame 24, and the guide rail frame 7 is used to place the guide tube.

[0050] After the guide tube bypasses the slide rail wheel 32, the medical staff will place the guide tube on the guide rail frame 7. When it is necessary to adjust the angle of the guide tube to make it bend, the medical staff will pinch the rotary knob 52 and then turn the guide rail frame 7, the guide rail frame 7 Drive the guide tube to rotate, and the angle of the guide tube can be adjusted to make it turn.

Abstract

The invention relates to the field of medical treatment, in particular to a universal valvular heart disease interventional instrument stabilizer which comprises a mounting supporting plate, a wedge-shaped connecting frame, an 8-shaped slotting frame, an arc-shaped connecting frame, a guide wire transmission assembly and the like. Two wedge-shaped connecting frames are fixedly installed on the top face of the installation supporting plate, the tops of the wedge-shaped connecting frames are fixedly connected with 8-shaped slotting frames, the right sides of the two 8-shaped slotting frames are jointly and fixedly connected with an arc-shaped connecting frame, and the two 8-shaped slotting frames are jointly and slidably connected with a guide wire transmission assembly. The rotary knob is clamped through the sliding round rod, so that the rotary knob does not rotate any more, the guide tube is fixed and does not continue to move forwards any more, it is guaranteed that the guide tube accurately reaches the lesion position, and displacement is avoided when the valve is released.

Description

technical field [0001] The invention relates to the medical field, in particular to a general-purpose stabilizer for interventional instruments for heart valve disease. Background technique [0002] Heart valvular disease is a common heart disease in my country, among which valvular damage caused by rheumatic fever is the most common. When the physiological structure or function of the valve annulus or valve leaflet is damaged due to aging, disease and other factors, valvular disease will occur, so the elderly Valvular heart disease, coronary heart disease, and valvular disease caused by myocardial infarction are becoming more and more common. With the aging population in my country, valvular heart disease has become a disease burden that cannot be ignored, but elderly and high-risk patients cannot tolerate traditional Surgical open-chest valve repair or replacement surgery makes transcatheter interventional therapy an important treatment method for high-risk groups. [0003]...
