Description

Technical Field

[0001] The utility model relates to the technical field of cosmetic needles, in particular to a combined cosmetic needle structure. Background Art

[0002] In cosmetic medicine practice, traditional acupuncture techniques face challenges primarily in three areas. These challenges not only impact treatment effectiveness but can also increase patient discomfort and risk during treatment. First, the traditional procedure involves the sequential use of sharp and blunt needles, with a sharp needle initially used to penetrate the skin to establish a channel, followed by a blunt needle for drug injection or microneedle therapy. This multiple punctures not only increase damage to the skin and subcutaneous tissue, prolonging recovery time, but can also exacerbate pain and reduce overall treatment satisfaction.

[0003] Secondly, while the oblique hole at the front of the sharp needle facilitates even drug distribution, it also carries a higher risk of vascular puncture. If the sharp needle accidentally enters a blood vessel during puncture, not only can the drug accidentally enter the bloodstream, triggering adverse reactions such as local bleeding, hematoma formation, or systemic side effects, but in severe cases, it can even threaten the patient's health and increase the uncertainty and risk of treatment.

[0004] Finally, the operation process of traditional cosmetic needle technology is relatively complicated, and the needle needs to be replaced after puncture. This process not only prolongs the operation time and increases the risk of infection, but also places higher demands on the doctor's operating skills, especially when dealing with sensitive areas such as the face. Any minor operational errors may have a significant impact on the final cosmetic effect. Utility Model Content

[0005] The purpose of the utility model is to provide a combined cosmetic needle structure that can reduce tissue damage, lower the risk of blood vessel puncture, and simplify the operation process.

[0006] The utility model provides a combined cosmetic needle structure, comprising: a syringe, wherein the liquid outlet end of the syringe is connected to a nozzle, and a sharp needle assembly is sleeved on one end of the syringe, wherein a blunt needle assembly is arranged inside the sharp needle assembly, and the sharp needle assembly and the blunt needle assembly are used in combination, wherein the sharp needle assembly comprises a sharp needle tube body, wherein the puncture end of the sharp needle tube body is processed with a bevel opening, and the blunt needle assembly comprises a blunt needle tube body arranged in the inner cavity of the sharp needle tube body, wherein the penetration end of the inner cavity of the blunt needle tube body is connected to a tube head.

[0007] In a specific embodiment, a tube set is installed at the end of the sharp needle assembly, and a slip ring groove is provided on the outer surface of the tube set.

[0008] In a specific embodiment, a plurality of bevel grooves are provided on the outer surface of the tube sleeve and in the inner cavity of the slip ring groove body, and a limiting through groove is provided on the surface of the tube sleeve and at one end of the inner cavity of the bevel groove body, wherein the limiting through groove is communicated with the inner cavity of the tube sleeve.

[0009] In a specific embodiment, a plurality of L-shaped grooves are formed at the end of the inner cavity of the tube set, and one end of the inner cavity end of the L-shaped groove is connected to an elastic pushing member.

[0010] In a specific embodiment, a sealing shielding member is bonded to the bottom of the inner cavity of the sharp needle tube body, and the sealing shielding member is used in conjunction with the drainage hole body.

[0011] In a specific embodiment, a ring shifting member is slidably provided in the inner cavity of the sliding ring groove body, and an extrusion protrusion is connected to the inner surface of the ring shifting member, wherein the extrusion protrusion is provided with a rounded corner.

[0012] In a specific embodiment, drainage holes are provided on the surface of the tube head, and the drainage holes are multiple and interconnected.

[0013] In a specific embodiment, the end of the blunt needle tube body is connected to a sleeve, wherein an annular slide is slidably sleeved on the outer surface of the sleeve, and the outer surface of the annular slide is connected to a limiting protrusion.

[0014] In a specific embodiment, the end of the sleeve surface is connected with a connecting strip, and the connecting strips are multiple and matched with the L-shaped groove.

[0015] In a specific embodiment, a plurality of elastic sleeves are sleeved on the end of the sleeve surface, and an elastic clamping ring is connected to the bottom of the elastic sleeve, and a slot for cooperating with the extrusion protrusion is opened at the end of the outer surface of the tube sleeve.

[0016] The beneficial effects of the present application are as follows: when aspirating a liquid medicine, the sharp needle assembly is inserted into the medicine bottle, the connection between the elastic clamp and the slot is released, and the blunt needle tube body is rotated to put the drainage hole body in a connected state, thereby aspirating the liquid medicine; conversely, when using the sharp needle tube body for subcutaneous puncture, it is only necessary to adjust the drainage hole body to contact the sealing shielding member to prevent the liquid medicine from flowing out and the blood from entering;

[0017] When the sharp needle tube body and the blunt needle tube body are combined for puncture, the oblique opening of the sharp needle tube body is used to pierce the patient's skin, and the dial ring is rotated to make the squeezing protrusion squeeze the limiting protrusion located in the limiting groove out of its hole, thereby releasing the limit between the sharp needle tube body and the blunt needle tube body, so that the sharp needle tube body is retreated a certain distance, so that the tube head of one end of the blunt needle tube body located in the sharp needle tube body is extended, and the blunt needle tube body and the tube head are used to move in the skin, thereby reducing the impact of the sharp needle tube body puncturing the subcutaneous tissue, and finally preventing the sharp needle tube body from continuing to penetrate the skin tissue;

[0018] Finally, by cleverly designing a blunt needle assembly inside the sharp needle assembly, the puncture ability of the sharp needle assembly is used to quickly penetrate the skin. Once the puncture is successful, the blunt needle assembly remains in place while the sharp needle assembly is withdrawn, avoiding the risk of blood vessel puncture caused by continued puncture of the oblique hole on the sharp needle assembly. This design not only simplifies the operation process and reduces damage to the skin and subcutaneous tissue, but also significantly reduces the risks during the treatment process and improves the safety, comfort and efficiency of cosmetic treatments.

[0032] Because traditional cosmetic acupuncture techniques use a step-by-step approach, first penetrating the skin with a sharp needle to establish a channel, followed by drug injection or microneedle treatment with a blunt needle, this approach poses challenges such as multiple punctures leading to additional tissue damage, a higher risk of vascular puncture, and a complex procedure, limiting treatment effectiveness and potentially increasing patient discomfort. Therefore, the inventors have developed a modular cosmetic acupuncture needle structure that, when used, utilizes a cleverly designed internal puncture mechanism to rapidly penetrate the skin. Once puncture is successful, the needle remains in place and is retracted, avoiding the risk of vascular puncture that could be caused by the upper oblique hole. This design not only simplifies the procedure and reduces damage to the skin and subcutaneous tissue, but also significantly reduces risks during treatment, improving the safety, comfort, and efficiency of cosmetic treatments, thereby addressing these shortcomings.

[0033] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0034] Please refer to Figures 1 to 10 , the embodiment of the utility model provides a combined cosmetic needle structure, comprising a syringe 100, the liquid outlet end of the syringe 100 is connected to a nozzle 110;

[0035] Specifically, the sharp needle assembly 200 is sleeved on one end of the syringe 100; the sharp needle assembly 200 includes a sharp needle tube body 210, wherein the puncture end of the sharp needle tube body 210 is processed with a bevel opening 211 for puncturing the patient's body, and a tube set 220 is installed at the end of the sharp needle assembly 200, and the tube set 220 is used to cooperate with the socket 330 to assemble the sharp needle tube body 210 and the blunt needle tube body 310. The outer surface of the tube set 220 is provided with a sliding ring groove 221 for installing the ring member 250;

[0036] Specifically, the outer surface of the tube sleeve 220 and the inner cavity of the slip ring groove 221 are provided with a plurality of oblique grooves 222 for adjusting the extrusion protrusion 251, and the oblique grooves 222 are arranged obliquely. The surface of the tube sleeve 220 and one end of the inner cavity of the oblique groove 222 are penetrated by a limiting groove 223, wherein the limiting groove 223 is communicated with the inner cavity of the tube sleeve 220, and finally, the tube sleeve 220, the limiting groove 223, The inner cavities of the oblique shifting groove 222 and the sliding ring groove 221 are in a mutually connected device, which is used to form an assembly space for the assembly of the limiting protrusion 332, the extrusion protrusion 251 and the shifting ring 250. The cooperation between the shifting ring 250 and the extrusion protrusion 251 can be used to squeeze the limiting protrusion 332 inserted in the limiting groove 223 out of its inner cavity, ultimately facilitating the sharp needle tube body 210 to be retracted a distance after puncture and the tube head 320 to be extended outward;

[0037] Specifically, a plurality of L-shaped grooves 224 are formed at the end of the inner cavity of the tube set 220, and one end of the inner cavity of the L-shaped groove 224 is connected to an elastic pusher 230, which is composed of a spring and an abutment plate. The spring is connected to the inner wall of the L-shaped groove 224, and the abutment plate is connected to the other end of the spring. The abutment plate is slidably connected to the inner cavity of the L-shaped groove 224, and is used to cooperate with the connecting strip 340 to slidably connect the blunt needle tube body 310 and the sharp needle tube body 210.

[0038] Specifically, a sealing shield 240 is bonded to the bottom of the inner cavity of the sharp needle tube body 210, and the sealing shield 240 is used in conjunction with the drainage hole body 321. When the tube head 320 is rotated until the drainage hole body 321 contacts the sealing shield 240, the inner cavity space of the blunt needle tube body 310 is blocked. When the tube head 320 is rotated until the drainage hole body 321 and the sealing shield 240 are in a non-contact state, infusion can be performed through the tube head 320 and the inner cavity of the drainage hole body 321;

[0039] Specifically, a shifting ring 250 is slidably provided in the inner cavity of the sliding ring groove 221, and an extrusion protrusion 251 is connected to the inner surface of the shifting ring 250, wherein the extrusion protrusion 251 is chamfered. When the shifting ring 250 drives the extrusion protrusion 251 to rotate in the sliding ring groove 221 to one end close to the limiting groove 223, due to the special shape of the sliding ring groove 221, the extrusion protrusion 251 can be driven to deviate when moving, and squeeze the limiting protrusion 332 in the limiting groove 223, so that it is separated from the limiting groove 223, thereby decomposing the sharp needle tube body 210 and the blunt needle tube body 310;

[0040] Specifically, the sharp needle assembly 200 is provided with a blunt needle assembly 300. The sharp needle assembly 200 and the blunt needle assembly 300 are used in combination to reduce damage to subcutaneous tissue during puncture. The blunt needle assembly 300 includes a blunt needle body 310 disposed in the inner cavity of the sharp needle body 210, wherein the penetration end of the inner cavity of the blunt needle body 310 is connected to a tube head 320;

[0041] Specifically, the surface of the tube head 320 is provided with a drainage hole body 321, and the drainage hole body 321 is multiple and interconnected, and is used to increase the liquid delivery rate of the tube head 320. In this way, when the drainage hole body 321 is in an unsealed state, an infusion channel is formed to transport the liquid medicine. When the drainage hole body 321 is punctured by the sharp needle tube body 210, the drainage hole body 321 is adjusted to a sealed state, which can prevent the inflow of blood when the sharp needle tube body 210 pierces the skin;

[0042] Specifically, the end of the blunt needle tube body 310 is connected to a sleeve 330, and the sleeve 330 is used in conjunction with the tube set 220, wherein the outer surface of the sleeve 330 is slidably sleeved with an annular slide 331, and the outer surface of the annular slide 331 is connected to a limiting protrusion 332, wherein the limiting protrusion 332 is inserted into the limiting groove 223 to fix the sharp needle tube body 210 and the blunt needle tube body 310; and the surface of the limiting protrusion 332 is rounded, which ultimately facilitates the removal of the direct limitation of the sharp needle tube body 210 and the blunt needle tube body 310, and facilitates the combined use of the sharp needle tube body 210 and the blunt needle tube body 310 when performing subcutaneous puncture;

[0043] Furthermore, a connecting strip 340 is connected to the end of the surface of the sleeve 330, and there are multiple connecting strips 340 that are adapted to the L-shaped groove 224. One end of the connecting strip 340 extends into the inner cavity of the L-shaped groove 224 and makes sliding contact with the connection therewith. When adjusting the state of the drainage hole body 321 on the tube head 320 and the sealing shield 240, it is only necessary to rotate the blunt needle tube body 310 so that the connecting strip 340 is in the inner cavity of the L-shaped groove 224 and squeezes the elastic pusher 230, thereby adjusting the connectivity of the drainage hole body 321 on the tube head 320.

[0044] Among them, the end of the surface of the sleeve 330 is sleeved with multiple elastic sleeves 350, and the multiple elastic sleeves 350 are spliced together to form a ring shape, and the bottom of the elastic sleeve 350 is connected with an elastic snap ring 351, and the end located on the outer surface of the tube sleeve 220 is provided with a slot for use with the extrusion protrusion 251, and the elastic snap ring 351 is inserted into the slot by the flexibility of the elastic sleeve 350 to limit the two. In this way, when the connecting strip 340 squeezes the elastic pusher 230, the elastic snap ring 351 and the slot are used to limit the elastic pusher 230 to prevent it from resetting.

[0045] In summary, the working principle of the combined cosmetic needle structure of the embodiment of the present invention is as follows: when aspirating liquid medicine, the sharp needle assembly 200 is inserted into the medicine bottle, the connection between the elastic clamp 351 and the slot is released, and the blunt needle tube body 310 is rotated to put the drainage hole body 321 in a connected state, thereby aspirating liquid medicine. Conversely, when using the sharp needle tube body 210 for subcutaneous puncture, it is only necessary to adjust the drainage hole body 321 to contact the sealing shield 240 to prevent the outflow of liquid medicine and the inflow of blood.

[0046] When the sharp needle body 210 and the blunt needle body 310 are combined for puncture, the bevel opening 211 of the sharp needle body 210 is used to pierce the patient's skin, and the ring 250 is rotated to make the extrusion protrusion 251 squeeze the limiting protrusion 332 located in the limiting groove 223 out of its hole, thereby releasing the limit between the sharp needle body 210 and the blunt needle body 310, so that the sharp needle body 210 retreats a certain distance, so that the blunt needle body located in the sharp needle body 210 The tube head 320 at one end of 310 is extended, and the blunt needle tube body 310 and the tube head 320 are used to move in the skin, reducing the impact of the puncture of the sharp needle tube body 210 on the subcutaneous tissue, and ultimately preventing the sharp needle tube body 210 from continuing to penetrate the skin tissue; and after the sharp needle tube body 210 is withdrawn outward, the sharp needle tube body 210 and the blunt needle tube body 310 can be separated, which is flexible to assemble and convenient to disassemble, and solves the inconvenience of separating the sharp needle assembly 200 and the blunt needle assembly 300 for use.

[0047] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
