Description

Technical Field

[0001] This utility model relates to the field of guide wire welding technology, and in particular to a medical guide wire welding device. Background Technology

[0002] The function of guidewires in endovascular interventional diagnosis and treatment is to guide other interventional medical devices, such as catheters and microcatheters, to the target site after entering the blood vessel lumen, navigating through intravascular channels, branches, and tortuous sections, and sometimes even overcoming narrowing areas. Guidewires play an irreplaceable guiding role when selectively entering coronary arteries in cases of coronary heart disease, small intracranial cerebral arteries, vascular malformations, and small blood supply vessels within tumors.

[0003] Medical guidewires are mostly made of nickel-titanium alloys or stainless steel, requiring extremely high welding precision. During the welding process, the angle needs to be adjusted to ensure welding quality. Currently, the device cannot adjust the angle of the welding torch during the welding process, resulting in improper welding angles and affecting the welding quality of the guidewire. Summary of the Invention

[0004] This utility model discloses a medical guide wire welding device, which aims to solve the technical problem that existing devices cannot adjust the angle of the welding torch during the welding process, resulting in improper welding angle and affecting the welding quality of the guide wire.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A medical guide wire welding device includes a tooling base. A mounting hole is formed on one outer wall of the tooling base. A drive motor is fixedly connected inside the mounting hole. The output shaft of the drive motor is connected to a rotating rod via a coupling. A transmission roller is fixedly connected to the outer wall of the rotating rod, and one end of the rotating rod is movably connected to one outer wall of the tooling base. Two guide rollers are provided on the inner wall of opposite sides of the tooling base. The outer walls of the two guide rollers and the transmission roller are provided with the same guide wire body. A welding chamber is provided on one outer wall of the tooling base, and a welding module is provided inside the welding chamber.

[0007] The device is equipped with a tooling base, a drive motor, transmission rollers, guide rollers, a wire guide body, a welding chamber, and a welding module. During use, the drive motor rotates the transmission rollers and guide rollers, which can stably transport the wire guide body. The welding chamber provides a relatively clean environment for the wire guide during welding. The welding module allows welding to be performed at various angles of the wire guide, improving welding efficiency and quality.

[0008] In a preferred embodiment, the welding module includes two fixed supports, both of which are fixedly connected to one outer wall of the tooling base. A common gear ring is fixedly connected to the opposite outer walls of the two fixed supports, and a limit tube is fixedly connected to one outer wall of the gear ring. An arc-shaped slider is movably connected to the outer wall of the limit tube, and a fixed plate is fixedly connected to the outer wall of the arc-shaped slider. A connecting frame is fixedly connected to one outer wall of the fixed plate. A servo motor is fixedly connected to the top of the connecting frame, and a frame is fixedly connected to one outer wall of the fixed plate. The output shaft of the servo motor is connected to a shaft member via a coupling, and one end of the shaft member is movably connected to one outer wall of the frame. A gear block is fixedly connected to the outer wall of the shaft member, meshing with the gear ring. A mounting bracket is fixedly connected to one outer wall of the frame. An electric push rod is fixedly connected to one outer wall of the mounting bracket. A protective cover is provided at the output end of the electric push rod, and the welding torch body is disposed inside the protective cover.

[0009] With the addition of a welding module, the welding angle can be adjusted to the most suitable angle based on the material and diameter of the guide wire, the shape of the welding area, and subsequent usage requirements. This ensures uniform heat distribution during welding, improves the welding quality of the guide wire, and allows operators to adjust the welding angle at any time based on actual observation and operational needs, adapting to different welding conditions and improving work efficiency and welding quality.

[0010] In a preferred embodiment, an air storage tank is fixedly connected to one outer wall of the tooling base, a delivery pipe is provided at the output end of the air storage tank, an air pump is provided on the outer wall of the delivery pipe, and the output end of the delivery pipe is connected to the interior of the welding chamber, and an observation window is provided on one outer wall of the welding chamber.

[0011] By installing a gas storage tank, a delivery pipe, and an air pump, the inert gas inside the gas storage tank can be delivered to the inside of the welding chamber through the delivery pipe and the air pump. During the welding process, a protective gas layer will be formed on the surface of the guide wire to prevent metal oxidation, ensure the metal properties of the weld, and prevent problems such as reduced strength and corrosion resistance caused by oxidation.

[0012] As can be seen from the above, the medical guide wire welding equipment provided by this utility model can adjust the welding torch body to the most suitable welding angle to ensure uniform distribution of welding heat, improve the welding quality of the guide wire, and during the welding process, the operator can adjust the welding angle at any time according to actual observation and operation needs to adapt to different welding conditions, thereby improving work efficiency and welding quality.
