Description

Technical Field

[0001] This utility model relates to the field of radiofrequency therapy equipment, and in particular to a radiofrequency probe assembly and device. Background Technology

[0002] Radiofrequency therapy devices use low-frequency electromagnetic waves to act on diseased tissues in the human body, causing polar water molecules within the tissues to move at high speeds, generating heat (i.e., endogenous heat effect). At low temperatures, proteins coagulate and lose their activity, and finally, through the body's rejection mechanism, they detach, thereby achieving the therapeutic goal.

[0003] When using existing radiofrequency therapy devices, the probe slides on the human body. However, the human body is uneven and irregular due to factors such as muscles, fat, and bones. When the probe slides on the human body, the pressure from the probe can cause discomfort, affecting the treatment effect and user experience of the radiofrequency therapy device.

[0025] See Figure 1 , Figure 2 An embodiment of this utility model provides a radio frequency probe assembly, including a connector 100, a probe 200, and a connecting shaft 300. The connector 100 is located at the rear of the radio frequency probe 200 assembly and is used to connect the radio frequency probe 200 assembly to a robot. The probe 200 is located at the head of the radio frequency probe 200 assembly and is used to act on the human body. The connecting shaft 300 connects the connector 100 and the probe 200 and is mainly used for force transmission. The probe 200 includes a first connecting plate 201, a second connecting plate 202, an electrode plate 203, and a spring 204. One end of the connecting shaft 300 is connected to the connecting seat 100, and the other end of the connecting shaft 300 is connected to the first connecting plate 201. The second connecting plate 202 is connected to the back side of the electrode plate 203. The first connecting plate 201 and the second connecting plate 202 are approximately perpendicular to the extension direction of the connecting shaft 300. The first connecting plate 201 and the second connecting plate 202 are spaced a certain distance apart along the extension direction of the connecting shaft 300. The spring 204 is disposed between the first connecting plate 201 and the second connecting plate 202. One end of the spring 204 is connected to the first connecting plate 201, and the other end of the spring 204 is connected to the second connecting plate 202.

[0026] Combination Figure 1 , Figure 2In the technical solution of this utility model, the probe 200 adopts a floating structure, that is, the electrode plate 203, which directly acts on the human body, is connected to the first connecting plate 201 through the spring 204, and further connected to the connecting seat 100 through the connecting shaft 300. In use, the radio frequency probe 200 assembly is installed on the robot, and the radio frequency energy is conducted from the robot host to the electrode plate 203 and then acts on the human body. When the radio frequency probe 200 assembly slides on the human body, the spring 204 automatically adjusts the elasticity according to the different heights and softness of the human body, so that the radio frequency probe 200 assembly can slide easily on the human body without causing discomfort or pain to the patient, thus alleviating the discomfort caused to the human body by the probe 200 sliding on the human body due to the different heights and softness of the human body.

[0027] The second connecting plate 202 can be connected to the electrode plate 203 by means of clips, screws, etc., to form an integral whole with the electrode plate 203. See also the following embodiments: Figure 2 The electrode plate 203 has a mounting base 205 extending towards the first connecting plate 201 on its back side. The mounting base 205 has external threads, and the second connecting plate 202 has a screw hole connected to the mounting base 205. In this embodiment, the first connecting plate 201 is directly connected to the electrode plate 203 via threads. After tightening, the second connecting plate 202 abuts against the electrode plate 203 from the back side, serving as the direct force-bearing part for the connection between the electrode plate 203 and the spring 204. In addition, the mounting base 205 on the back side of the electrode plate 203 can also provide a connection position for the radio frequency line and temperature sensor on the electrode plate 203, facilitating the arrangement and installation of the radio frequency line and temperature sensor.

[0028] Spring 204 may be provided in one or more forms, for example, in some embodiments, see [reference needed]. Figure 2 The second connecting plate 202 is provided with multiple second spring mounting holes 206, which are distributed around the screw hole. The first connecting plate 201 is provided with multiple first spring mounting holes 207 corresponding to the second spring mounting holes 206. One end of the spring 204 is installed in the first spring mounting hole 207, and the other end of the spring 204 is installed in the second spring mounting hole 206. In this embodiment, by using multiple springs 204 arranged circumferentially along the probe 200, the electrode plate 203 can more freely adjust its posture, thereby better adjusting the elasticity automatically according to the different heights and softness of the human body, making the radio frequency probe 200 assembly slide easily on the human body.

[0029] It is understandable that the spring 204 can be directly connected to the first connecting plate 201 and the second connecting plate 202 by means of screws or clips without providing spring mounting holes.

[0030] In some embodiments, see Figure 1 , Figure 2The connector 100 has a hollow inner cavity 101, within which a main board 102 is housed. The connecting shaft 300 has a shaft core inner hole 301. The mounting base 205 of the electrode plate 203 is connected to a first wire 214. The first wire 214 passes through the shaft core inner hole 301, extends into the inner cavity 101, and connects to the main board 102. The first wire 214 serves as a radio frequency line and is fixed to the mounting base 205 of the electrode plate 203 using brass terminals and screws. The main board 102 has a control circuit for controlling the electrode plate 203, etc. In use, it is electrically connected to the robot to set parameters such as heating temperature through the robot's operating interface.

[0031] In some embodiments, see Figure 2 The mounting base 205 of the electrode plate 203 is equipped with a temperature sensor 208. The temperature sensor 208 is connected to a second wire 209, which passes through the inner hole 301 of the shaft core, extends to the inner cavity 101, and is connected to the main board 102. The temperature sensor 208 can be a thermistor. The temperature sensor 208 measures the real-time temperature of the electrode plate 203 of the deep radio frequency probe 200 assembly and transmits it to the main board 102 to control the temperature change in real time.

[0032] In some embodiments, see Figure 2 The connector 100 has an axial recess 103 at one end near the probe. The RF probe assembly also includes an LED ring 401 and an LED ring connector 402. The LED ring 401 is fitted onto the LED ring connector 402, which is installed in the axial recess 103, and presses the LED ring 401 axially onto the end of the connector 100. In this embodiment, the LED ring 401 can light up during use, indicating the working status of the RF probe assembly and enhancing the overall ambiance of the RF probe assembly.

[0033] Further, see Figure 2 The lamp ring connector 402 is provided with an axial insertion hole 403. The connecting shaft 300 is inserted into the axial insertion hole 403. The lamp ring 401 is connected to a third wire 404. The third wire 404 passes through the inner hole 301 of the shaft core, extends to the inner cavity 101, and is connected to the main board 102. The main board 102 realizes the control of the lamp ring 401. In this embodiment, the third wire 404 shares the inner hole 301 of the shaft core with the second wire 209 and the first wire 214, which facilitates assembly and avoids safety hazards caused by exposed wires.

[0034] See Figure 2The bottom of the inner cavity 101 is provided with an axial screw hole, and a fastening screw 405 is provided in the screw hole to lock the connecting shaft 300, the lamp ring connector 402 and the connecting seat 100. During assembly, first, the lamp ring 401 is fitted onto the lamp ring connector 402, then the lamp ring connector 402 is inserted into the axial recess 103 of the connecting seat 100, then the connecting shaft 300 is inserted into the axial insertion hole 403 of the lamp ring connector 402, and finally the fastening screw 405 is passed through the screw hole to fasten and lock the connecting shaft 300, the lamp ring connector 402 and the connecting seat 100. In this embodiment, the fastening screw 405 can be hidden in the inner cavity 101, avoiding the screw from being exposed and improving the product quality.

[0035] In some embodiments, see Figure 1 , Figure 2 The probe 200 also includes a probe rear cover 210, which has a connecting shaft through hole 211. The probe rear cover 210 is located on the back side of the first connecting plate 201, and the connecting shaft 300 passes through the connecting shaft through hole 211. The outer edge of the electrode plate 203 has a probe enclosure 212 extending towards the probe rear cover 210. The probe rear cover 210 is connected to the probe enclosure 212 and defines a probe inner cavity 213 inside. The first connecting plate 201, the second connecting plate 202, and the spring 204 are located in the probe inner cavity 213. In use, the radio frequency probe assembly is installed on the robot. The radio frequency energy is conducted from the robot host to the electrode plate 203 and then acts on the human body. When the radio frequency probe assembly slides on the human body, the spring 204 automatically adjusts its elasticity according to the height and hardness of the human body. The probe rear cover 210 and the electrode plate 203 float together along the axial direction of the connecting shaft 300, so that the radio frequency probe assembly can easily slide on the human body. In this embodiment, the probe rear cover 210 and the electrode plate 203 are connected by a detachable method such as a threaded connection, which can facilitate the assembly and disassembly of the entire probe 200 on the connecting shaft 300. At the same time, the probe rear cover 210 can cooperate with the first connecting plate 201 to prevent the electrode plate 203 from detaching from the probe 200.

[0036] In some embodiments, see Figure 2 The connecting shaft 300 is provided with a sleeve 302 at the position where it passes through the connecting shaft through hole 211 to reduce wear on the connecting shaft 300 during probe 200 floating.
