Description

Technical Field

[0001] The utility model relates to the field of soldering tools, in particular to a soldering tool for medical guide wires. Background Art

[0002] PTCA guidewire is a medical guidewire specially used for coronary interventional treatment. Its function is to pass through the coronary artery stenosis or occlusion lesions to the distal end of the blood vessel, providing a "track" for the balloon catheter or stent to be delivered to the stenosis lesion for pressurization and expansion. It is mainly composed of a spring, a wire core and a medical coating.

[0003] In the prior art, during the production and processing of guidewires, when soldering the spring and the wire core, workers usually use their hands to fix the two objects. However, in such a delicate operation as soldering, even extremely slight hand shaking or looseness may cause the relative position between the spring and the wire core to change, thereby affecting the welding quality. Therefore, soldering tooling for medical guidewires is needed. Utility Model Content

[0005] The utility model also provides a soldering tool with the above-mentioned medical guide wire, including a connecting plate, the upper surface of the connecting plate is fixedly connected to the first bearing block and the second bearing block respectively, the upper surface of the connecting plate is fixedly connected to two bearing rods, the side inner walls of the two bearing rods are fixedly connected to the guide rods, and the outer surfaces of the two guide rods are slidably connected to the same connecting block, the upper surface of the connecting block is fixedly connected to the handle, and the lower surface of the connecting block is fixedly connected to the first fixing block and the second fixing block respectively, the first fixing block is provided with a plurality of first limiting grooves, the second fixing block is provided with a plurality of second limiting grooves, the first bearing block is provided with a plurality of first positioning grooves, the second bearing block is provided with a plurality of second positioning grooves, the outer surfaces of the two guide rods are slidably sleeved with springs, and the diameters of the first limiting groove, the second limiting groove, the first positioning groove and the second positioning groove increase from back to front.

[0006] One end of the spring is fixedly connected to the upper surface of the connecting block, and the end of the spring away from the connecting block is fixedly connected to the top inner wall of the bearing rod, so that the connecting block, the first fixed block and the second fixed block can automatically move upward.

[0007] A sliding groove is provided on the bearing rod, and the outer surface of the connecting block is slidably connected to the sliding groove, so that the connecting block can move smoothly.

[0008] The second fixing block is located on the top side of the second bearing block, and the first fixing block is located on the top side of the first bearing block.

[0010] There are four docking blocks and they are distributed in a rectangular array.

[0011] The guide rod passes through the connecting block, and the connecting block is in a cross shape.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] 1. By setting up the structures such as the handle, the first fixing block and the second fixing block, after pressing the handle, the first fixing block and the second fixing block can be moved downward, thereby achieving the fixation between the two objects. Even if the hand moves slightly during welding, since the hand is not in direct contact with the object, as long as the pressing force can be maintained, the shaking of the object can be reduced and the quality of welding can be improved. In addition, the tooling is provided with multiple fixing grooves of different diameters, so that objects of different diameters can be fixed, thereby improving the practicality of the tooling.

[0014] 2. Through the setting of the spring, when the pressed handle is released, the first fixed block and the second fixed block can automatically move away from the first bearing block and the second bearing block under the action of the spring, without the need to manually pull the handle upward, thereby further increasing the practicality of the tooling.
