Description

Technical Field

[0001] The present invention relates to the technical field of facial plastic surgery, and particularly to an injection device for facial microsurgery. Background Art

[0002] Microsurgery is a medical technology that uses high-tech. It has the characteristics of not requiring surgery and being able to make people look beautiful and younger in a short time. It has gradually replaced traditional plastic surgery and has the advantages of safety, no wound, and a short recovery period. The emergence of microsurgery makes plastic surgery as simple as doing beauty skin care, and at the same time, the plastic surgery effect is exactly the same as that of traditional plastic surgery. The main items of microsurgery include botulinum toxin type A for wrinkle removal and face slimming, injection of whitening needles, etc.

[0003] Currently, when performing facial microsurgery, it is often necessary to use a syringe to inject medicine into the face multiple times. Common syringes mainly consist of a syringe barrel (with scale lines), a needle, a piston, a piston shaft, and a piston handle. When in use, the syringe is first filled with medicine, and then the piston handle, piston shaft, and piston are pushed to inject the medicine in the syringe barrel into the face through the needle. Since facial microsurgery requires multiple small amounts of medicine to be injected at different positions, and the amount of medicine injected each time is judged and operated by medical staff based on experience, the accuracy of the medicine injection amount is poor, and strict accurate quantitative injection cannot be achieved, making it very inconvenient to use. In related technologies, a positioning mechanism is installed on the syringe, and by rotating the sleeve, the positions of the arc-shaped piece and the stopper can be adjusted through the threaded rod. Through the position of the arc-shaped piece on the scale line of the syringe barrel, the amount of medicine injected each time can be judged, and when the piston handle is pushed, the stopper can block the piston handle after the quantitative medicine injection is completed to prevent over-injection, achieving accurate quantitative injection. However, in actual use, the adjustment method of the positioning mechanism is relatively complex, and it is integrally set with the syringe, increasing the use cost and being inconvenient for staff to use.

[0036] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0037] It should be noted that all the directional indications in the embodiments of the present application are only used to explain the relative position relationship and movement conditions between components in a specific posture. If this specific posture changes, the directional indications will also change accordingly.

[0038] In the present application, unless otherwise clearly defined and limited, terms such as "connection" and "fixation" shall be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0039] In addition, in the present application, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present application.

[0040] During facial microplastic surgery, it is often necessary to use a syringe to inject medicine into the face multiple times. The medicine is drawn into the syringe in advance, and then the piston handle, piston shaft, and piston are pushed to inject the medicine in the syringe into the face through the needle head.

[0041] In the related art, a positioning mechanism is installed on the syringe, and by rotating the sleeve, the positions of the arc-shaped piece and the stopper can be adjusted through the threaded rod. The amount of medicine injected each time can be judged by the position of the arc-shaped piece on the scale line of the syringe barrel. When the piston handle is pushed, the stopper can block the piston handle after the injection of a fixed amount of medicine to prevent over-injection, achieving precise quantitative injection. However, in actual use, the adjustment method of the positioning mechanism is relatively complex, and it is integrally set with the syringe, increasing the use cost and being inconvenient for the staff to use.

[0042] To solve the problems in the related art to a certain extent, the embodiment of the present application provides an injection device for facial microplastic surgery. When in use, only the positions of the two limit blocks 25 need to be adjusted before injection, so as to adjust the movement range of the piston rod 11, achieve precise injection, be more convenient and fast, and improve the convenience of the device.

[0043] The present application will be described below with reference to the accompanying drawings and specific embodiments:

[0044] Combined with Figures 1 - 6 , the embodiment of the present application provides an injection device for facial microplastic surgery, including: a syringe barrel 10, inside which a piston rod 11 is slidably connected. One end of the syringe barrel 10 is provided with a needle head 12. A first ring body 20 is slidably connected to the outside of the syringe barrel 10, and the connection between the first ring body 20 and the side surface and the outer wall of the syringe barrel 10 is tightly attached. A first plate body 21 is fixedly connected to the first ring body 20. A second ring body 22 is slidably connected to the syringe barrel 10. The other end of the first plate body 21 is fixedly connected to the second ring body 22. A second plate body 23 is slidably connected to the first plate body 21. A third plate body 24 is slidably connected to the second plate body 23. Limit blocks 25 are fixedly connected to the bottoms of the second plate body 23 and the third plate body 24. Locking bolts 26 are threadedly connected to the second plate body 23 and the third plate body 24. A fourth plate body 30 is fixedly connected between the first ring body 20 and the second ring body 22. A connecting block 31 is fixedly connected to one end of the fourth plate body 30. A locking bolt 32 is threadedly connected to the connecting block 31, and one end of the locking bolt 32 is inserted into the syringe barrel 10.

[0045] After assembling the device, place the needle 12 into the medicine. After the medicine drawing operation, keep the needle 12 upward. By pushing the first plate body 21 and the second plate body 23, adjust the position of the limit blocks 25 at the bottom of the first plate body 21 and the second plate body 23. Finally, rotate the two first set bolts 26 to fix the positions of the first plate body 21 and the second plate body 23, thereby fixing the positions of the two limit blocks 25. Then, after inserting the needle 12 into the skin, push the piston rod 11 to make the piston rod 11 inject the medicine into the patient's body through the needle 12 to complete the injection operation. After the injection is completed, rotate the second set bolt 32 so that one end of it slides out of the syringe 10. After canceling the limit on the connecting block 31, pull the second ring body 22 outward. After the second ring body 22 drives the connecting block 31 to disengage from the syringe 10, directly pull the first ring body 20 outward. After the first ring body 20 drives the second ring body 22 to slide out from the outside of the syringe 10 through the first plate body 21 and the fourth plate body 30, disassemble the first ring body 20, the first plate body 21, the second ring body 22, the second plate body 23, the third plate body 24, and the limit block 25, and perform disinfection to facilitate subsequent reuse. Conversely, implement the installation. Finally, discard the disassembled syringe 10.

[0046] In some embodiments, slide rails 27 are fixedly connected to both the first plate body 21 and the second plate body 23, making the sliding of the second plate body 23 and the third plate body 24 more stable.

[0047] In some embodiments, a first chamfer 28 is provided on the first ring body 20, making the inner side of the first ring body 20 close to the syringe 10 to facilitate subsequent fixation.

[0048] In some embodiments, a plurality of first plate bodies 21 are provided between the first ring body 20 and the second ring body 22, enabling the second plate bodies 23, the third plate bodies 24, and the limit blocks 25 on the plurality of first plate bodies 21 to be used simultaneously, thereby improving the limiting effect.

[0049] In some embodiments, a first cylinder 40 is clamped on the outside of the first ring body 20. A second cylinder 41 is slidably connected in the first cylinder 40. A third cylinder 42 is slidably connected in the second cylinder 41. A round head rod 43 is slidably connected to the first cylinder 40. A spring 44 is sleeved on the outside of the round head rod 43. The round head rod 43 is connected to the first cylinder 40 through the spring 44. A hole body 45 is provided on the first ring body 20. One end of the round head rod 43 is inserted into the hole body 45.

[0050] After a single injection is completed, pull the third cylinder 42 outwards. While the third cylinder 42 slides out of the second cylinder 41, pull the second cylinder 41 out of the first cylinder 40. The third cylinder 42, the second cylinder 41, and the first cylinder 40 play a role in covering and protecting the needle 12. Moreover, by pulling the round-headed rod 43 outwards, while it slides out of the hole body 45, the spring 44 is pulled, causing the first cylinder 40 to disengage from the first ring body 20. Subsequently, pull the first cylinder 40 to make the first cylinder 40 and its upper structure fall off from the first ring body 20, facilitating subsequent maintenance and improving practicability.

[0051] In some embodiments, both the second cylinder 41 and the third cylinder 42 are T-shaped cylinders to prevent the second cylinder 41 and the third cylinder 42 from falling off.

[0052] In some embodiments, the round-headed rod 43, the spring 44, and the hole body 45 form a group, and multiple groups are provided on the first cylinder 40. Multiple round-headed rods 43 work simultaneously to improve the limiting effect on the first cylinder 40.

[0053] In some embodiments, a second chamfer 50 is provided on the outer side of the round-headed rod 43, and a push block 51 is fixedly connected to the outer side of the second plate body 23. When adjusting the position of the second plate body 23, it drives the push block 51 to move. Thus, after the push block 51 contacts the second chamfer 50, it pushes the round-headed rod 43 to slide outwards, canceling the limit on the first cylinder 40 and facilitating the subsequent disassembly of the first cylinder 40.

[0054] In some embodiments, a groove is provided on the outer side of the first ring body 20, so that the first cylinder 40 is closely attached to the groove on the first ring body 20, making the connection between the first ring body 20 and the first cylinder 40 more firm.

[0055] In some embodiments, the distance between the opposite sides of the first cylinder 40 and the third cylinder 42 is greater than the length of the needle 12, so that the first cylinder 40, the second cylinder 41, and the third cylinder 42 can all play a good role in covering and protecting the needle 12.

Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. In addition, those skilled in the art can combine and combine the different embodiments or examples described in this specification.
