Description

Technical Field

[0001] This utility model relates to the field of probe welding technology, and in particular to a medical high-frequency probe silver welding device. Background Technology

[0002] High-frequency medical probes play a crucial role in medical testing and treatment, demonstrating remarkable effectiveness. In ultrasound diagnosis, they can emit and receive high-frequency ultrasound waves, thereby generating clear and precise images of internal organs and tissues, allowing doctors to observe tissue structures in minute detail. To facilitate the welding of the probes, a medical high-frequency probe silver welding device is required.

[0003] A search revealed Chinese Patent Publication No. CN219465210U, which discloses a blade probe welding device. The device includes a micrometer, a micrometer support, a welding base, a positioning drive mechanism for controlling the probe length, a clamping plate for holding and fixing the blade, and a probe limiting block. The micrometer passes through the micrometer support and is in movable contact with the positioning drive mechanism. The micrometer support is connected to the welding base. The welding base has a block-shaped protrusion for positioning the probe. The block-shaped protrusion and the probe limiting block together form a probe receiving groove. Both the probe limiting block and the welding base have bolt holes, and the probe limiting block is fixed to the welding base by bolts. The welding base has a sliding groove and a fixed blade groove for positioning the blade. The positioning drive mechanism is located in the sliding groove. This device has a simple structure and is easy to operate. By adjusting the position of the needle tip positioning block with the micrometer, the blade and probe can be placed in the corresponding positions for welding. This not only ensures the quality of the finished product but also saves costs. However, in actual use, the lack of a positioning structure to adjust the position of the probe and wire feeder makes it prone to incomplete welds and air bubbles due to positioning issues, thus reducing the reliability of the device. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a medical high-frequency probe silver welding device, which aims to improve the problem of void welding and bubbles caused by the lack of positioning structure in the welding device in the prior art.

A spring block is fixedly connected to the bottom front side of the fixing frame. A spring rod is fixedly connected to the right side of the fixing frame. An upper positioning pin is fixedly connected to the bottom of the spring rod.

[0009] The above technical solution utilizes the telescopic function of the spring rod to flexibly adjust the position of the upper positioning pin, so as to cooperate with the lower positioning pin to fix the probe.

[0013] As a further description of the above technical solution:

[0014] A knob is rotatably connected to the top of the top plate, and the bottom of the knob passes through the top plate and is fixedly connected to the threaded rod.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Specifically, first, fix the probe on the lower positioning pin 22. Then, rotate the threaded rod 4. With the help of the threaded connection, the lifting block 6 moves up and down along the guide rod 5. Then, rotate the second gear 9. Relying on the meshing transmission principle, drive the first gear 7 and the mounting plate 8 above it to rotate synchronously, thereby achieving precise adjustment of the position of the wire feeder 10. After completing the above steps, start the wire feeder 10 and rotate the probe to add silver wire to the part of the probe surface that needs to be welded. Finally, turn on the heater 12 to heat up the heating wire 13, and then the welding operation can be carried out.

[0041] Reference Figure 1 , Figure 2 and Figure 5 The positioning mechanism 2 includes a hollow rod 201, which is fixedly connected to the top left side of the base 1. The hollow rod 201 has pre-drilled holes 203 on both the upper and lower sides of its outer side. A telescopic spring 202 is fixedly connected to the bottom of the inner side of the hollow rod 201. A fixing frame 204 is fixedly connected to the top of the telescopic spring 202. A spring block 205 is fixedly connected to the bottom of the front side of the fixing frame 204. A spring rod 206 is fixedly connected to the right side of the fixing frame 204. An upper positioning pin 207 is fixedly connected to the bottom of the spring rod 206.

[0042] Specifically, by utilizing the telescopic function of the spring rod 206, the position of the upper positioning pin 207 can be precisely adjusted, thereby working in conjunction with the lower positioning pin 22 to achieve a stable fixation of the probe. When facing the fixation requirements of probes of different specifications, press the spring block 205 to retract it into the fixing frame 204, thus releasing its engagement with the pre-drilled hole 203. At this time, flexibly adjust the vertical height of the fixing frame 204 along the hollow rod 201. Subsequently, the compressed spring block 205 releases its stored elastic potential energy, extends again, and engages with the corresponding pre-drilled hole 203, thereby completing the precise locking of the position of the fixing frame 204.

[0043] Reference Figure 2 , Figure 3 and Figure 4 A handle 20 is rotatably connected to the right side of the lifting block 6, and the outer side of the lifting block 6 passes through the handle 20 and is fixedly connected to the second gear 9; a knob 15 is rotatably connected to the top of the top plate 14, and the bottom of the knob 15 passes through the top plate 14 and is fixedly connected to the threaded rod 4; a handle 18 is fixedly connected to the outer side of both the fixing plate 11 and the fixing block 3, and a protective sleeve 19 is fixedly connected to the outer side of the handle 18.

[0044] Specifically, the handle 20 facilitates the rotation of the second gear 9, the operating knob 15 facilitates the rotation of the threaded rod 4, the handle 18 facilitates the gripping and carrying of the device, and the protective sleeve 19 on it enhances the comfort of gripping.

[0045] Reference Figure 1 , Figure 3 and Figure 5 The base 1 has positioning blocks 16 fixedly connected to all four sides of its outer wall, and positioning holes 17 are provided on the outer side of the positioning blocks 16; the base 1 has a controller 23 fixedly connected to its right side, and the controller 23 is electrically connected to the wire feeder 10 and the heater 12 respectively; the hollow rod 201 has brackets 21 fixedly connected to its front and rear sides of its outer wall, and the bottom of the brackets 21 is fixedly connected to the base 1.

[0046] Specifically, by installing threaded parts in the positioning holes 17 on the positioning block 16, the device can be easily installed and fixed. The controller 23 can easily control the start-up and operation between the wire feeder 10 and the heater 12. The bracket 21 can improve the firmness of the fixation between the hollow rod 201 and the base 1.

[0047] Working principle: Before using the device, the probe is first fixed by placing it on the lower positioning pin 22. Then, the threaded rod 4 is rotated to drive the lifting block 6 to move up and down along the guide rod 5 through the threaded connection. The second gear 9 is rotated to drive the first gear 7 and its mounting plate 8 to rotate through meshing transmission to adjust the position of the wire feeder 10. Then, the wire feeder 10 is started and the probe is rotated to add silver wire to the surface where it needs to be welded. Then, the heater 12 is started to heat the heating wire 13 to perform welding.

[0048] Furthermore, the position of the upper positioning pin 207 can be adjusted by the extension and retraction of the spring rod 206, so as to cooperate with the lower positioning pin 22 to fix the probe. When it is necessary to fix probes of different specifications, the spring block 205 is pressed to retract into the fixing frame 204 to release its engagement with the reserved hole 203. At this time, the height of the fixing frame 204 can be adjusted along the hollow rod 201. Then, the elastic potential energy is released by the compressed spring block 205, which can extend the spring block 205 and engage with the corresponding reserved hole 203, thereby fixing the position of the fixing frame 204.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
