Abstract
Description
Technical Field
[0001] This utility model belongs to the field of welding intracardiac ultrasound harnesses and grounding plates for ICE (Intracardiac Electrosurgical Unit), and relates to a device for welding intracardiac ultrasound harnesses and grounding plates for ICE. Background Technology
[0002] Intracardiac ultrasound (ICE) is an advanced medical imaging technology that uses a catheter to insert an ultrasound probe into the heart, enabling real-time, high-resolution imaging of the intracardiac structures. This technology plays a crucial role in cardiac interventional surgery because it helps doctors monitor the catheter position more accurately and identify complications in a timely manner, thereby improving the success rate and safety of the procedure. With the continuous development and improvement of the technology, ICE is expected to play an even more important role in future cardiac interventional surgeries. Data transmission between the probe and the outside world in ICE mainly relies on the intracardiac ultrasound harness. The components of ICE include the intracardiac ultrasound harness, grounding plate, and fixation sleeve.
[0003] In existing intracardiac ultrasound harnesses, grounding plates, and fixing sleeves, the continuous welding process causes the fixing block connected to the welding head to heat up, leading to deformation and downward movement. This downward movement of the fixing block, in turn, causes the welding head to move downward, exceeding the required welding height. This results in the welding head deforming the fixing sleeve and extruding solder paste from the connection point between the intracardiac ultrasound harness and the grounding plate into the solder groove. Ultimately, this leads to poor welding results between the intracardiac ultrasound harness and the grounding plate, as well as excessive deformation or even damage to the fixing sleeve. Therefore, to solve the above technical problems, the technical solution of this application is proposed. Utility Model Content

[0009] Furthermore, the two ends of the second connector are connected to the fixing member and the fixing block respectively by studs, and the fixing block is also connected to the upper part of the welding head by studs.
[0010] Furthermore: the limiting component includes a limiting member, the top of which is connected to the fixing member by a stud, and at least two limiting pins are connected to the lower part of the limiting member, with the upper end face of the limiting pin abutting against the lower end face of the fixing block respectively.

[0023] The features and performance of this utility model will be further described in detail below with reference to the embodiments.
[0024] Example 1
[0025] This utility model relates to a device for welding intracardiac ultrasound bundles and grounding plates in ICE (Intracardiac Electrosurgical Unit), as shown in Figure 1. It includes a vertically arranged base plate 1, with a fixing member 2 at the front of the base plate 1. One side of the fixing member 2 is connected to the base plate 1 via several rolling components.
[0026] The upper end face of the fixing member 2 is connected to the upper end face of the base plate 1 through the first connecting member 3. One side of the first connecting member 3 is fixed to the base plate 1 through a stud, and the other side of the first connecting member 3 is telescopically connected to the fixing member 2 through an elastic component. A fixing block 4 is provided on one side of the lower end face of the fixing member 2. The fixing block 4 is connected to the fixing member 2 through the second connecting member 5. A welding head 6 is connected below the fixing block 4. A limiting component is provided on the other side of the lower end face of the fixing member 2. The working end of the limiting component abuts against the lower end face of the fixing block 4.
[0027] The specific implementation method of this embodiment is as follows: During the welding process of the existing intracardiac ultrasound harness, grounding plate, and fixing sleeve, the welding head continuously welds, which causes the fixing block connected to the welding head to heat up, resulting in deformation of the fixing block. This causes the fixing block to move downward, and during the downward movement of the fixing block, it drives the welding head to move downward, causing the welding head to exceed the height required for welding. This results in the welding head deforming the fixing sleeve and squeezing the solder paste at the connection between the intracardiac ultrasound harness and the grounding plate into the welding groove. Ultimately, this leads to poor welding effect between the intracardiac ultrasound harness and the grounding plate, and also causes excessive deformation or even damage to the fixing sleeve.
[0028] This application uses fixing components and limiting pins on the entire support frame to control the deformation of the fixing block as it moves downward, ensuring that the fixing block can only deform upward. Elastic components are also provided on the fixing components, allowing the fixing block and welding head to have space for upward deformation. Furthermore, by using at least two limiting pins, the height of the lower end of the fixing block remains constant. This prevents deformation at the welding points where the welding head welds the fixing sleeve, the intracardiac ultrasound bundle, and the grounding plate, thus ensuring a stable weld between the fixing sleeve and the intracardiac ultrasound bundle, and between the intracardiac ultrasound bundle and the grounding plate. This, in turn, improves the quality of the fabricated intracardiac ultrasound bundle.
[0029] At the same time, it improves the precision of the preparation of intracardiac ultrasound bundles, so that the intracardiac ultrasound bundles are welded to the plastic fixing sleeves without deformation, and the intracardiac ultrasound bundles are welded to the grounding plates firmly and fully, so that the intracardiac ultrasound bundles have stable quality, thereby facilitating the improvement of the stability of the entire intracardiac ultrasound technology.
[0030] Preferably, both the second connector and the limiting pin are made of non-conductive material, which avoids the current being transmitted to the limiting member, the fixing member, the first connector, and the substrate through conductivity, thus avoiding the problem of these components overheating and causing greater deformation.
[0031] Example 2
[0032] This utility model relates to a device for welding intracardiac ultrasound bundles and grounding plates in ICE (Intracardiac Electrosurgical Unit). As shown in Figure 1, the rolling assembly includes a cross roller bearing 7, the fixed end of which is fixedly connected to the fixing member 2, and the rolling end of which is movably connected to the base plate 1.
[0033] The elastic component includes a heavy-duty compression spring 8. The top of the fixing member 2 is provided with a blind hole 9 for placing the heavy-duty compression spring 8. One end of the heavy-duty compression spring 8 is connected to the first connecting member 3, and the other end of the heavy-duty compression spring 8 is connected to the bottom of the inner wall of the blind hole 9.
[0034] The two ends of the second connector 5 are connected to the fixing member 2 and the fixing block 4 respectively by studs. The fixing block 4 is also connected to the upper part of the welding head 6 by studs.
[0035] The specific implementation method of this embodiment is as follows: the fixing member is movably connected to the first connecting member and the base plate through a heavy-duty compression spring and a cross roller bearing. The purpose of this arrangement is to allow the fixing member and the fixing block to have upward movement space, so that the fixing block deforms when heated, and the deformation is also transferred upward, avoiding the problem of driving the welding head to move downward.
[0036] Studs facilitate fixing and disassembly.
[0037] Example 3
[0038] This utility model is used for welding intracardiac ultrasound bundles and grounding plates of ICE. As shown in Figure 1, the limiting component includes a limiting member 10. The top of the limiting member 10 is connected to the fixing member 2 through a stud. At least two limiting pins 11 are connected to the lower part of the limiting member 10. The upper end face of the limiting pin 11 abuts against the lower end face of the fixing block 4.
[0039] The welding head 6 is rectangular in shape. A stepped groove 12 is provided on the lower end face of the welding head 6. The higher part of the stepped groove 12 is used for welding the fixing sleeve, and the lower part of the stepped groove 12 is used for welding the intracardiac ultrasound bundle and the grounding plate.
[0040] The welding head 6 is provided with an opening groove 13, and the two sides of the top of the welding head 6 are respectively connected to the power supply through wires.
[0041] The specific implementation method of this embodiment is as follows: the limiting component and the limiting pin cooperate to restrict the downward movement of the fixed block, thereby avoiding the downward deformation of the fixed block.
[0042] By setting an open slot on the welding head, the heat generated by the current at the welding end of the welding head is maximized and more uniform, which facilitates the welding of intracardiac ultrasound bundles, grounding plates, and fixing sleeves. At the same time, setting a stepped slot facilitates the welding of intracardiac ultrasound bundles, grounding plates, and fixing sleeves in one go.
[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions and improvements made by those skilled in the art within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
