Description

Technical Field

[0001] The utility model relates to the field of medical-related equipment, in particular to a new injection needle for medical cosmetology. Background Art

[0002] Medical cosmetology refers to the use of drugs, surgery, medical devices and other traumatic or irreversible medical techniques to repair and reshape a person's appearance and the shape of various parts of the body. Nowadays, medical cosmetology is developing rapidly. Common medical surgeries include injecting drugs subcutaneously through needles to make the skin appear plump, bright and more youthful.

[0003] For example, the "new type of syringe needle" proposed in the publication number "CN213994476U" includes an empty barrel and a nipple formed at one end of the empty barrel, and the nipple is used in conjunction with a needle plug. In this scheme, the length of the needle used is fixed, but the skin thickness of different patients is different, so generally, experienced doctors will control the length of the needle for injections to avoid some unnecessary risks. However, with the development of the times, some cosmetic drugs no longer need to be injected in specific hospitals, and can be injected by patients themselves. Since patients have less experience in injections, they cannot control the depth of needle insertion. If it is too deep, it will cause unnecessary trauma and pain, and if it is too short, it cannot reach the target tissue. Therefore, the utility model proposes a new type of injection needle for medical beauty to solve the above problems. Summary of the invention

[0004] The utility model aims to provide a novel injection needle for medical cosmetology, which can effectively control the length of the pillow and reduce the difficulty of injection for the injector.

[0005] The purpose of the utility model is achieved as follows: a new type of injection needle for medical cosmetology, comprising a cylinder, a rear end outer wall of the cylinder is provided with a thread, a sealing ring is sleeved on the thread, a needle is slidably connected inside the cylinder, a driving mechanism is provided on the cylinder, and the driving mechanism drives the needle to slide back and forth in the cylinder, so that the driven needle can extend from the front end of the cylinder or be retracted into the cylinder; a plurality of support rods are arranged around the outer side of the cylinder, each of the support rods is provided with an automatic telescopic mechanism, and a gasket is provided on the bottom surface of each automatic telescopic mechanism.

[0006] Compared with the prior art, the beneficial effects of the utility model are:

[0007] 1. Through the automatic telescopic mechanism, that is, the rotation of the gear, the toothed plate meshing with the gear is moved, and then the toothed plate is fixedly connected to the needle, thereby driving the needle to move up and down. Finally, the gear is limited by the limiting mechanism, and the telescopic length of the needle can be freely adjusted, so that the patient can freely control the needle length during injection to prevent unnecessary risks.

[0008] 2. Multiple support rods are fixedly installed on the outside of the cylinder, and an automatic telescopic mechanism is fixedly installed on the bottom of each support rod, and a gasket is connected to the bottom of each automatic telescopic mechanism. When the patient injects himself, the gasket will first rest on the skin, and then preliminarily position the needle to prevent the patient from not being able to grasp the insertion position of the needle due to inconvenience when injecting himself.

[0009] In summary, the utility model is easy to operate during use, and is convenient for patients to freely control the length of the needle during injection, thereby preventing unnecessary risks. The needle can be preliminarily positioned during injection, thereby facilitating the insertion of the needle into the desired position. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0015] Reference Figure 1-3A new type of injection needle for medical cosmetology comprises a cylinder 1, a thread 10 is arranged on the outer wall of the rear end of the cylinder 1, a sealing ring 11 is sleeved on the thread 10, a needle 2 is slidably connected inside the cylinder 1, a driving mechanism is arranged on the cylinder 1, and the driving mechanism drives the needle 2 to slide back and forth inside the cylinder 1, so that the driven needle 2 can extend from the front end of the cylinder 1 or be retracted into the cylinder 1; a plurality of support rods 3 are arranged around the outer side of the cylinder 1, each of the support rods 3 is provided with an automatic telescopic mechanism, and a gasket 5 is arranged on the bottom surface of each automatic telescopic mechanism.

[0016] The utility model can be threadedly connected to a syringe via a thread 10 and can be prevented from leaking via a sealing ring 11 .

[0017] The cylinder 1 is provided with a driving mechanism, wherein the driving mechanism includes a tooth plate 16 and a gear 8; the tooth plate 16 extends forward and backward and is installed on the outer side of the needle 2, the gear 8 is rotatably connected to the cylinder wall of the cylinder 1, and the gear 8 is meshed with the tooth plate 16; the tooth plate 16 is moved by rotating the gear 8, thereby driving the needle 2 to slide up and down, and adjusting the telescopic length of the needle 2;

[0018] A limiting mechanism is provided on the outside of the cylinder 1, so that the gear 8 is limited in rotation by the limiting mechanism. The limiting mechanism includes two fixing seats 6, and each fixing seat 6 is fixedly mounted on the outer wall of the cylinder 1; a clamping shaft 7 is slidably connected to any of the fixing seats 6, and a plurality of clamping grooves 13 are provided on the wall rings on both sides of the gear 8, and the sliding clamping shaft 7 makes the clamping shaft 7 clamp or disengage from the corresponding clamping groove 13. Through the limiting mechanism, when the needle 2 is extended to the required length, the gear 8 can be limited, thereby preventing it from rotating, and the position of the tooth plate 16 is fixed, and the needle 2 is fixed.

[0019] The outer side of the cylinder 1 is provided with a plurality of support rods 3, each of which is provided with an automatic telescopic mechanism, and the bottom surface of each automatic telescopic mechanism is provided with a gasket 5. The automatic telescopic mechanism here includes a telescopic rod 4, and each telescopic rod 4 is fixedly installed on the bottom surface of the support rod 3 at a corresponding position. The telescopic rod 4 includes a sleeve rod and an extension rod, and each sleeve rod is fixedly installed on the bottom surface of the support rod 3 at a corresponding position; the extension rod is slidably connected in the sleeve rod, and a spring 12 is installed between the bottom wall of the sleeve rod and the top surface of the extension rod.

[0020] The gasket 5 is fixedly mounted on the bottom surface of the sleeve rod, and the sleeve rod is flush with the bottom surface of the cylinder 1. Through the automatic telescopic mechanism, when the doctor is giving an injection to the patient, he can first press the gasket 5 against the patient's skin for preliminary positioning. At the same time, through the elasticity of the spring 12, when the needle 2 is moved, the gasket 5 always presses against the patient's skin and does not affect the operation of the needle 2.

[0021] The cylinder 1 has an injection channel 15 extending from front to back, and the front and rear ends of the injection channel 15 are bonded with sealing films 9. When not in use, the needle 2 is completely hidden in the cylinder 1, and the front end of the cylinder 1 is bonded with a sealing film 9 to prevent the needle 2 in the cylinder 1 from being contaminated by bacteria.

[0023] When the utility model is used, the sealing films 9 at the front and rear ends of the cylinder 1 are first opened, and then the cylinder 1 is threadedly connected to the syringe to be used through the thread 10 provided on the cylinder 1. At the same time, a sealing ring 11 is sleeved on the thread 10 so that the cylinder 1 and the syringe will not leak.

[0024] Then, the gear 8 can be rotated to mesh with the toothed plate 16 fixedly installed on the outside of the needle 2, thereby driving the needle 2 to move downward; then, a fixed seat 6 is fixedly installed on the outside of the cylinder 1, and the fixed seat 6 is slidably connected with a clamping shaft 7, and then the clamping shaft 7 on the fixed seat 6 is pressed to clamp it in the clamping groove 13 opened on the gear 8, thereby limiting the position of the gear 8 and preventing it from rotating. By fixing the toothed plate 16, the telescopic length of the needle 2 is fixed, and finally the beauty medicine is sucked into the syringe through the needle 2.

[0025] When an injection is required, a support rod 3 is fixedly installed on the outside of the cylinder 1, and a telescopic rod 4 is fixedly installed at the bottom of each support rod 3; since a spring 12 is installed inside the telescopic rod 4, the gasket 5 buried at the bottom of the telescopic rod 4 will first rest on the patient's skin to preliminarily position the needle 2, so as to prevent some interns or patients from inserting the needle 2 in the wrong position due to nervousness or hand shaking during injection. At the same time, the setting of the support rod 3 can also prevent the cylinder 1 from being directly affected by collision when it accidentally falls to the ground, thereby protecting the needle 2.
