Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an auxiliary heating device for the negative electrode plate of an electrosurgical unit. Background Technology

[0002] High-frequency electrosurgical units are widely used in surgical procedures due to their advantages such as accelerating the surgical process and reducing intraoperative bleeding. However, during surgery, hypothermia can easily occur, causing discomfort to the patient upon skin contact. Therefore, a device for heating the negative electrode plate is needed.

[0003] A search revealed a Chinese utility model patent with publication number CN219963047U, which discloses an auxiliary heating device for an electrosurgical negative electrode plate. According to its description, when using the negative electrode plate to treat a patient, to prevent discomfort caused by the plate's low temperature upon contact, the negative electrode plate must be placed on a heating plate before use. At this time, a pressure switch senses the weight change and connects the current to the heating coils, causing both coils to begin heating. During heating, the temperature of the heating coils can be adjusted using a temperature control button, or the internal temperature of the heating plate can be monitored in real time via a temperature display screen. A temperature sensor detects the temperature and sends this information to the display screen. When the temperature sensor detects that the preset temperature has been reached, the heating coils stop working, and the normal operation indicator light turns red, indicating that the negative electrode plate has finished heating.

[0004] However, the above heating device has the following problems: when heating the negative electrode plate, it can only heat the entire negative electrode plate, while the patient may experience localized overheating, and it cannot heat the localized areas. If the entire negative electrode plate is heated, other areas will overheat, causing discomfort to the patient. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an auxiliary heating device for the negative electrode plate of an electrosurgical unit, thereby solving the problems mentioned in the background section.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

The heating section includes a box with an open top. The negative electrode plate is fastened to the box. Multiple columns arranged in a matrix are fixed inside the box. Support plates are connected to the columns. Heating coils are provided inside the support plates. After the negative electrode plate is fastened to the box, the support plates contact the bottom surface of the negative electrode plate. All the heating coils form a parallel circuit, and each circuit is equipped with a temperature control switch.

[0008] Preferably, the housing is equipped with a controller, all heating coils are electrically connected to the controller, and a power cord is also connected to the controller.

[0009] Preferably, the exterior of the housing is equipped with a touch screen, which is electrically connected to the controller. The touch screen has touch buttons that correspond one-to-one with the temperature control switch, and the temperature control switch can be turned on or off by the touch buttons.

[0010] Preferably, the column is provided with a wiring channel, and the wires on the heating coil pass through the wiring channel and are electrically connected to the controller.

[0011] Preferably, the upper end of the housing is provided with a boss near the opening, and a plurality of positioning holes are provided on the boss. The bottom of the negative electrode plate is connected to a positioning post that matches the positioning holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The column and support plate provide support and prevent the negative electrode plate from collapsing. The heating coil is located inside the support plate. When local heating is needed, simply turn off the temperature control switch at the corresponding location, and the heating coil will heat the local area of ​​the negative electrode plate without heating the entire negative electrode plate, thus improving patient comfort.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] Example 1

[0021] Please see Figure 1-4 An auxiliary heating device for an electrosurgical unit's negative electrode plate includes a heating section and a negative electrode plate 1 fastened to the heating section. The heating section includes a box 2 with a top opening. The negative electrode plate 1 is fastened to the box 2. Multiple columns 3 arranged in a matrix are fixed inside the box 2. Support plates 4 are connected to the columns 3. Heating coils 5 are provided inside the support plates 4. Wiring channels 10 are provided inside the columns 3. After the negative electrode plate 1 is fastened to the box 2, the support plates 4 are in contact with the bottom surface of the negative electrode plate 1. All heating coils 5 form a parallel circuit, and each circuit is equipped with a temperature control switch 6, which is close to the heating coil 5.

[0022] The housing 2 houses a controller 7, and all heating coils 5 are electrically connected to the controller 7. Specifically, the wires on the heating coils 5 pass through the wiring channel 10 and are then electrically connected to the controller 7. A power cord 8 is also connected to the controller 7. The exterior of the housing 2 is equipped with a touch screen 9, which is electrically connected to the controller 7. The touch screen 9 has touch buttons corresponding to the temperature control switches 6, and these buttons control the temperature control switches 6 to turn on or off. The temperature of each temperature control switch can be set via the touch screen 9. When the heating coil temperature reaches the set value, the temperature control switch is turned off, and the heating coil stops working.

[0023] The working principle of this embodiment is as follows:

[0024] The negative electrode plate 1 is placed on the box 2 and supported by the column 3 and the support plate 4 to prevent the negative electrode plate 1 from collapsing. The heating coil 5 is set inside the support plate 4. When local heating is required, the temperature control switch 6 at the corresponding position can be turned off by controlling the touch button on the touch screen 9. The heating coil 5 will then heat the negative electrode plate 1 locally instead of heating the entire negative electrode plate 1, thus improving the patient's comfort.

[0025] Example 2

[0026] The difference between this embodiment and Embodiment 1 is that a boss 11 is provided at the upper end of the housing 2 near the opening, and a plurality of positioning holes 12 are formed on the boss 11. The bottom of the negative electrode plate 1 is connected to a positioning post 13 that matches the positioning holes. When the negative electrode plate 1 is placed on the boss, the positioning post and the positioning holes cooperate to prevent the negative electrode plate from shaking.
