Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary equipment technology, specifically a shock-resistant high-frequency electrocautery device. Background Technology

[0002] High-frequency electrocautery, as the core of modern minimally invasive cosmetic surgery equipment, has always focused on surgical precision and safety in its technological evolution. It mainly utilizes RF radiofrequency waves to directly penetrate the skin surface through a handheld electrode head, generating heat energy by causing skin cells to resonate and rotate strongly. This achieves the purpose of heating collagen tissue and cell tissue, instantly raising the temperature of the skin's deeper layers. This stimulates the dermis to produce collagen, tightening it and promoting collagen regeneration. At the same time, it can also rearrange the fibrous tissue layer. During treatment, the deep layers of the skin can be heated, while the surface layer of the skin remains at a normal temperature. It has the effect of filling wrinkles and eliminating scars, effectively improving wrinkles, forehead lines, frown lines, crow's feet, etc., and is particularly suitable for the treatment of facial atrophic scars.

[0003] However, the high-frequency electrocautery device operates rapidly with its solenoid valves, which generates significant vibration and noise. During beauty treatments, the vibration can often affect the staff's work performance and the accuracy of the needle application. Furthermore, the noise can disrupt the tranquility of the environment and easily trigger adverse reactions in patients. Utility Model Content

[0004] The purpose of this invention is to provide a shock-resistant high-frequency electrocautery device to solve the problems mentioned in the background art, such as the rapid operation of the solenoid valve during the operation of the high-frequency electrocautery device, which generates obvious vibration and noise. During the beauty treatment, the vibration of the device often affects the working state of the staff, affects the accuracy of the needle application, and the noise also disrupts the tranquility of the environment to a certain extent, which can easily trigger adverse reactions in patients.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shock-resistant high-frequency electrocautery device, comprising a housing and a shock-resistant solenoid valve assembly, wherein a base plate is threadedly connected to the lower interior of the housing, a main control circuit board is disposed on the left side of the upper end face of the base plate, a negative pressure pump is electrically connected to the lower right side of the main control circuit board, the negative pressure pump is electrically connected to a manifold solenoid valve, and the negative pressure pump assembly is electrically connected to the shock-resistant solenoid valve assembly.

[0006] Preferably, the anti-vibration solenoid valve assembly includes a two-position three-way solenoid valve, a silencer, quick-connect fittings, bottom shock-absorbing cotton, back shock-absorbing cotton, front shock-absorbing cotton, top shock-absorbing cotton, and a mounting bracket. The two-position three-way solenoid valve is electrically connected to the top of the main control circuit board. The silencer is fixedly connected to the right side of the two-position three-way solenoid valve. A protrusion is fixedly connected to the front of the two-position three-way solenoid valve, and a quick-connect fitting is inserted into the surface of the protrusion. A quick-connect fitting is inserted into the left side of the two-position three-way solenoid valve. Two sets of quick-connect fittings are provided.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This invention forms an omnidirectional buffer layer by setting up bottom shock-absorbing cotton 604, back shock-absorbing cotton 605, front shock-absorbing cotton 606, and top shock-absorbing cotton 607. It employs a differentiated slotted design and a nested protrusion structure to absorb impact energy in the XYZ triaxial directions.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[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] Please see Figure 1-3One embodiment of this utility model is a shock-resistant high-frequency electrocautery device, comprising a housing 1 and a shock-resistant solenoid valve assembly 6. A base plate 2 is threadedly connected to the lower interior of the housing 1. A main control circuit board 3 is disposed on the left side of the upper end face of the base plate 2. A negative pressure pump 4 is electrically connected to the lower right side of the main control circuit board 3. The negative pressure pump 4 is electrically connected to a manifold solenoid valve 5 and the shock-resistant solenoid valve assembly 6.

[0021] Furthermore, the anti-vibration solenoid valve assembly 6 includes a two-position three-way solenoid valve 601, a silencer 602, a quick-connect coupling 603, bottom shock-absorbing cotton 604, back shock-absorbing cotton 605, front shock-absorbing cotton 606, top shock-absorbing cotton 607, and a mounting bracket 608. The two-position three-way solenoid valve 601 is electrically connected to the top of the main control circuit board 3. The silencer 602 is fixedly connected to the right side of the two-position three-way solenoid valve 601. A protrusion is fixedly connected to the front of the two-position three-way solenoid valve 601, and a quick-connect coupling 603 is inserted into the surface of the protrusion. A quick-connect coupling 603 is inserted into the left side of the two-position three-way solenoid valve 601. There are two sets of quick-connect couplings 603. The bidirectional insertion structure of the quick-connect coupling 603, combined with the noise reduction design of the silencer 602, shortens the pipeline connection time, and controls the insertion and extraction force of the coupling within the range of 3-5N, which ensures airtightness and reduces the risk of misoperation.

[0022] Furthermore, a bottom damping cotton 604 is bonded to the bottom of the two-position three-way solenoid valve 601, a back damping cotton 605 is bonded to the back of the two-position three-way solenoid valve 601, and a front damping cotton 606 is bonded to the front of the two-position three-way solenoid valve 601. The front damping cotton 606 has a square opening that corresponds to the protrusion fixedly connected to the front of the two-position three-way solenoid valve 601. A top damping cotton 607 is bonded to the top of the two-position three-way solenoid valve 601. By setting the bottom damping cotton 604, the back damping cotton 605, the front damping cotton 606, and the top damping cotton 607, an omnidirectional buffer layer is formed. The differential slotted design and the protrusion nesting structure achieve impact energy absorption in the XYZ three-axis direction, so that the displacement deviation of the solenoid valve assembly under acceleration impact is controlled, ensuring the stability of high-frequency current output and avoiding the risk of energy mutation caused by mechanical vibration.

[0023] Furthermore, the outer side of the top shock-absorbing cotton 607 is fitted with a fixing bracket 608. The front of the fixing bracket 608 has an opening that corresponds to the protrusion that is fixedly connected to the front of the two-position three-way solenoid valve 601. The four bottom corners of the fixing bracket 608 are threaded to connect to the base plate 2. The directional opening of the fixing bracket 608 enables quick positioning and installation, and the maintenance and replacement time is relatively reduced compared to the traditional welded structure.

[0024] Working principle:

[0025] Step 1: After the equipment is powered on, the main control circuit board 3 initiates a self-test program, sequentially verifying the initial states of the negative pressure pump 4, the manifold solenoid valve 5, and the anti-vibration solenoid valve assembly 6 via electrical connections. The threaded locking structure of the bottom shock-absorbing cotton 604 and the fixing bracket 608 works together to ensure the physical stability of the solenoid valve assembly under vibration, preventing signal misinterpretation caused by mechanical displacement during the self-test. At this time, the airtightness test of the quick-connect coupling 603 is completed simultaneously, and the silencer 602 enters standby mode to reduce system noise.

[0026] Step 2: After receiving the operation command, the main control circuit board 3 drives the negative pressure pump 4 to generate a preset negative pressure. The flow rate is adjusted by the manifold solenoid valve 5 and transmitted to the anti-vibration solenoid valve assembly 6. The two-position three-way solenoid valve 601 switches the air passage according to the command. The composite shock absorption structure formed by the top shock-absorbing cotton 607 and the fixing frame 608 effectively absorbs the XYZ axial vibration energy.

[0027] Step 3: Safe Termination and Rapid Maintenance

[0028] After the procedure, the main control circuit board 3 sends a termination signal, the negative pressure pump 4 stops working, and the manifold solenoid valve 5 closes the air passage. The operator can quickly disconnect the pipeline using the two-position three-way solenoid valve 601, and the silencer 602 simultaneously suppresses exhaust noise. During maintenance, the directional opening of the mounting bracket 608 and the four-corner threaded connection structure of the base plate 2 allow tools to disassemble from a single direction. Combined with the modular adhesive design of the shock-absorbing cotton, the entire solenoid valve assembly can be replaced in a short time.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description.
