Description
Technical Field
[0001] The utility model belongs to the field of medical cosmetology equipment, and specifically relates to a single-needle radio frequency handle for medical cosmetology. Background Art
[0002] Radiofrequency treatment is to transmit the radiofrequency energy emitted by the coaxial radiofrequency line through the needle to penetrate the surface layer of the skin and reach the dermis, thereby stimulating collagen proliferation through the heating of radiofrequency energy, prompting the rearrangement of elastic fibers, and thus achieving the effect of tightening the skin. It has the characteristics of being targeted, specific to the symptoms, and having sufficient energy. During the radiofrequency treatment process, a single-needle radiofrequency handpiece is required. However, the existing single-needle radiofrequency handpiece has a relatively simple structure and mostly uses an elastic pressing piece to pressurize and limit the sterile needle. During use, it is easy to have treatment failures such as the pre-buried sterile needle is not firm or the sterile needle falls off. At the same time, when designing existing single-needle RF handpieces, one single-needle RF handpiece can only be used with one model and size of sterile needle, and the overall applicability is poor. Moreover, when installing the coaxial RF line, the existing single-needle RF handpieces mostly use a single limit, that is, a limit connection between the coaxial RF line and the handle core, and the connection stability is poor. It is easy for the single-needle RF handpiece and the coaxial RF line to become disconnected during use. Therefore, in order to solve the above problems, it is necessary to develop a single-needle RF handle for medical beauty with a stable and reasonable structural design, good use effect and strong applicability. Utility Model Content
[0003] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a single-needle radiofrequency handle for medical beauty with a stable and reasonable structural design, good use effect and strong applicability.
[0004] The purpose of the utility model is achieved as follows: a single-needle radiofrequency handle for medical cosmetology, comprising an upper handle section, a sterile needle and a tightening screw, the upper handle section being a tubular structure as a whole, a handle core being slidably penetrated therein, the front end thread being detachably connected to the front handle section, the rear end thread being detachably connected to the lower handle section, and a threaded through hole being provided on the upper surface of the upper handle section near one end of the front handle section, a sterile needle limiting groove being provided at the center of the front end face of the handle core, a coaxial radiofrequency wire fixing groove being provided at the center of the rear end face, a through groove being provided at a position on the upper surface corresponding to the threaded through hole, and the through groove and the sterile needle limiting groove being communicated with each other. The center of the front section of the handle is provided with a plug hole, and the lower section of the handle is also a tubular structure, the rear end of which is threadedly connected to the rear section of the handle, and the interior of the connection between the lower section of the handle and the rear section of the handle is connected to a wire pressing plate by a screw; the needle tip of the sterile needle is located outside the front section of the handle, and the other end is inserted through the plug hole and is located inside the sterile needle limiting groove at the center of the front end surface of the handle core; the tightening screw thread is rotated and penetrated into the threaded through hole, and its lower end is located inside the upper section of the handle, and is concentrically fixedly connected with a pressure block that cooperates with the through groove structure, and the bottom of the pressure block is located in the sterile needle limiting groove through the through groove, and is in close contact with the sterile needle.
[0005] Furthermore, arc-shaped gripping grooves are provided on both sides of the outer surface of the upper section of the handle, and silicone soft pads are fixedly bonded inside the gripping grooves.
[0006] Furthermore, the middle position of the outer surface of the lower section of the handle is recessed toward the center to form a buffer structure, and the interior of the buffer structure is evenly provided with anti-slip lines.
[0007] Furthermore, the upper end of the tightening screw is located outside the upper section of the handle and is coaxially fixedly connected to an auxiliary rotating block.
[0008] Furthermore, a positioning plate is fixedly provided at the front end inside the upper section of the handle, a square hole is opened at the center of the positioning plate, and a square block matching the square hole structure is provided on the front end fixed sleeve of the outer surface of the handle core.
[0009] The beneficial effects of the utility model are as follows: the utility model is provided with a tightening screw, a pressure block, a threaded through hole and a through groove. When in use, the tightening screw can be rotated by an external force. At this time, the threaded connection between the tightening screw and the threaded through hole can be used to move vertically while the tightening screw is rotated, so that the pressure block is driven to move by the movement of the tightening screw, and the lower end of the pressure block is in close contact with the sterile needle inside the sterile needle limiting groove. At this point, the friction force generated by the close contact between them can be used to limit the sterile needle. Compared with the existing single-needle radio frequency handpiece that uses an elastic pressure piece to limit the sterile needle, the utility model adopts this structure, and its limiting effect is better, and the sterile needle is installed more firmly. At the same time, using this structure, the utility model can also be applicable to the installation and use of 0.4 mm sterile needles and 0.6 mm sterile needles, thereby increasing its applicability.
[0010] By providing a coaxial radio frequency wire fixing groove and a wire pressing plate, the coaxial radio frequency wire fixing groove can be used to achieve a limiting connection between the coaxial radio frequency wire and the handle core, thereby completing the primary fixation of the coaxial radio frequency wire. The wire pressing plate can be used in conjunction with the locking of the screw to achieve the limiting of the coaxial radio frequency wire and the lower section of the handle, thereby completing the secondary fixation of the coaxial radio frequency wire. With this structure, the two-fixation method is used to increase the stability of the connection between the utility model and the coaxial radio frequency wire.
[0011] By setting a positioning plate, a square hole and a square block, and utilizing the cooperation of the square hole and the square block, the threaded through hole and the through groove can be concentrically set during the sliding installation of the handle core inside the upper part of the handle through a positioning installation method, thereby increasing the convenience of operation when tightening the screw rod for subsequent installation; in general, the utility model has the advantages of stable and reasonable structural design, good use effect and strong applicability.
