LU601239B1 - A supportive device for guiding catheters in cardiovascular internal medicine - Google Patents

Abstract

This invention application relates to the technical field of interventional aids for guide catheter insertions and discloses in particular a cardiovascular interventional aid for guide catheter insertions, comprising: a first disc and a second disc. A mounting groove for a fixed retaining bracket is provided on the surface of the first disc, in which a fixed retaining bracket is attached. The advantageous effect is that a fixed retaining bracket is installed in the mounting groove, while a clamping plate holder is attached in the mounting groove for the clamping plate. When the clamping plate is fully retracted in the clamping groove, leaving a gap between the rubber pad and the guide wire, the guide wire can be easily withdrawn further from the first and second discs and used. After the guide wire has been inserted into the target position, the clamping plate is moved downwards, so that the guide wire is securely fixed between the clamping plate and the fixed retaining bracket. This reliably locks the guide wire without any sliding friction between the guide wire, the retaining bracket, and the rubber pad. This prevents wear and enables long-term use of the device.

Invention.

Example 1: Please refer to Figures 1 to 3. The present

The invention offers the following technical solution: A cardiovascular

Guide wire intervention aid device, consisting of a first disc 1 and a second disc 2. The first disc 1 and the second disc 2 are connected via

Screws are connected to each other. On the surface of the first disc 1 is a

Mounting groove 3 is provided for a fixing bracket, in which a fixing bracket 4 is firmly mounted. On the surface of the second disc 2, there is a mounting groove 5 for a

A clamping bracket is provided in which a clamping bracket 6 is fixedly mounted. A clamping groove 8 is provided on its underside, into which a clamping plate 13 is movably inserted. A rotatable surface is provided on the surface of the second disc 2.

A guide wire axis 7 is mounted, to whose surface one end of the guide wire is fixed; a handle is attached to the guide wire axis 7. A spring plate 9 is attached to the inner wall of the clamping groove 8, on whose surface a

The telescopic rod 10 is movably inserted. A wedge block 11 is attached to the upper end of the telescopic rod 10, and the clamping plate 13 is fixed to the lower end, on whose

There is a rubber pad 14 on the underside.

In actual use, the first disc 1 and the second

Disc 2 is connected to each other via screws. One end of the guide wire is attached to the axis of the guide wire axis 7, the other end runs through the

A gap exists between mounting groove 3 for the fixing bracket and mounting groove 5 for the clamping bracket, and leaks from the first and second discs. In the

Mounting groove 3 is where the fixing bracket 4 is mounted, and mounting groove 5 is where the

Clamping bracket 6. When the clamping plate 13 is fully seated in the clamping groove 8, leaving a gap between the rubber pad 14 and the guide wire, the guide wire can be easily pulled out of the device and reused. Once the guide wire has reached the target position, the clamping plate 13 is moved downwards, clamping the guide wire between the

Clamping plate 13 and the fixing bracket 4 are fixed in place — thus a stable fixation is achieved. Since there is a space between the guide wire, the fixing bracket 4 and the

Since there is no sliding friction in the rubber pad 14, wear and tear is avoided, which allows for long-term use.

Exemplary embodiment 2: Building upon exemplary embodiment 1, the upper surface of the wedge block 11 is provided with a slope to control the movement of the clamping plate 13. A first spring 12 is mounted on the shaft of the telescopic rod 10, the upper end of which presses against the underside of the wedge block 11 and the lower end of which

The end abuts the top of the spring plate 9. The clamping plate holder 6 has an inverted L-shaped rod structure. In the crossbar of the LU601239

The clamping plate holder 6 has a sliding plate groove 15 recessed in which a

The sliding plate 17 is slidably connected. A second spring 16 is attached between one end of the sliding plate 17 and the inner wall of the sliding plate slot 15.

On the surface of the clamping plate holder 6 there is a groove 18 for the

Gearshift lever in which a gearshift lever 19 is slidably connected. One end of the

The shift lever 19 protrudes into the sliding plate slot 15 and is on the surface of the

The sliding plate 17 is attached, while the other end protrudes from the groove 18.

To move the clamping plate 13 upwards, the shift lever 19 is actuated. This moves in the groove 18 and thereby displaces the push plate 17, so that it is completely pulled out of the clamping groove 8 and into the

The thrust plate slot 15 is returned. In doing so, the second spring 16 is compressed. Simultaneously, the first spring 12, which is held in place by the spring plate 9 and the

Wedge block 11 is compressed and, due to its elasticity, is pushed upwards, thus moving wedge block 11 upwards. Wedge block 11 moves via the

Telescopic rod 10 moves the clamping plate 13 upwards. To move the clamping plate 13 downwards, it is sufficient to release the shift lever 19. The second spring 16, due to its own elasticity, moves the sliding plate 17 back into the clamping groove 8. The sliding plate 17 slides over the inclined surface of the wedge block 11 and presses it downwards, which in turn moves the clamping plate 13 over the

The telescopic rod is moved downwards by 10 centimeters.

In actual use, the first disc 1 and the second

Disc 2 is attached with screws. The fin end of the guide wire is on the axis of the

The guide wire carrier 7 is attached, the other end runs between the mounting groove 3 of the fixing bracket and the mounting groove 5 of the clamping plate bracket and exits from the first disc 1 and the second disc 2. The mounting groove 3 is

When the clamping plate 13 is fully in the clamping groove 8 and a gap remains between the rubber pad 14 and the guide wire, the

The guide wire can be easily pulled out of the device and used. Once the guide wire has reached the target location, the clamping plate 13 is moved downwards so that the guide wire is positioned between the clamping plate 13 and the

Fixing bracket 4 is secured. This ensures the wire is firmly attached without any sliding friction between the wire, fixing bracket 4, and rubber pad 14. This prevents wear and tear and enables long-term use.

When the clamping plate 13 needs to be moved upwards, the shift lever 19 is actuated, which pulls the push plate 17 out of the clamping groove 8 and into the push plate slot 15. This compresses the second spring 16. Simultaneously, the first spring 12 is pushed upwards by the spring plate 9 and the wedge block 11, which in turn raises the clamping plate 13. To lower the clamping plate 13, it is sufficient to...

Releasing the shift lever 19: The second spring 16 presses the push plate 17 into the

The clamping groove 8 slides over the slope of the wedge block 11 and moves it downwards, thereby lowering the clamping plate 13 via the telescopic rod 10.
