[0002] Plastic surgery refers to the use of surgery, drugs, medical devices and other medical techniques to repair and reshape a person's appearance and the shape of various parts of the human body. Traditional facial plastic surgery operations mostly use syringes to fill injectable drugs or inject other liquids to achieve cosmetic effects. However, when injecting liquids into the patient's maxillofacial area with a syringe, the doctor relies on his or her experience to insert the syringe according to the required injection location. However, since there are many nerves in the maxillofacial area, there is a risk of touching the patient's maxillofacial nerves during injection, which reduces the safety of plastic surgery.

[0003] In order to solve the above problems, an injection positioner is generally used to ensure the accuracy of needle insertion.

DETAILED DESCRIPTION

[0013] The present invention is further described in detail below through specific implementation methods:

[0014] like Figure 1 As shown, one embodiment of the utility model proposes a maxillofacial injection positioner for plastic surgery, including a maxillofacial fitting cover 1, the maxillofacial fitting cover 1 has a first adjustment block 2 arranged to rotate along a first direction, the first adjustment block has a second adjustment block 3 arranged to rotate along a second direction, and the second adjustment block 3 is provided with an injection hole.

[0015] This maxillofacial injection locator for plastic surgery sets the injection hole on the second adjustment block 3. By rotating the first adjustment block 2 at a certain angle along the first direction, the injection hole can be tilted at a certain angle along the first direction; by rotating the second adjustment block 3 at a certain angle along the second direction, the injection hole can be tilted at a certain angle along the second direction; the tilt direction and tilt angle of the injection hole can be adjusted according to needs, and its application is more extensive.

[0016] In this embodiment:

[0017] The maxillofacial fitting mask 1 is an existing structure, and reference can be made to the corresponding structure in CN217366785U; the first direction is the horizontal direction, that is, the rotation axis of the first adjustment block 2 is arranged along the horizontal direction; the second direction is the vertical direction, that is, the rotation axis of the second adjustment block 3 is arranged along the vertical direction.

[0018] In order to facilitate the rotation adjustment of the first adjustment block 2 and the second adjustment block 3, as shown in FIG. Figure 1 and Figure 2 As shown, according to another embodiment of the present invention, a maxillofacial injection positioner for plastic surgery is provided, wherein the first adjustment block 2 and the second adjustment block 3 are both provided with an adjustment component 4 for driving them to rotate; the first adjustment block 2 or the second adjustment block 3 is rotated by the adjustment component 4, so as to quickly adjust the inclination direction and inclination angle of the injection hole.

[0019] Based on the above scheme:

[0020] The adjustment assembly 4 includes a protective shell 41, a driving bevel gear 42 and an adjustment handle 43; wherein, the protective shell 41 is fixedly connected to the first adjustment block 2 or the maxillofacial fitting cover 1; the driving bevel gear 42 is rotatably set in the protective shell 41 and is engaged with a driven bevel gear 44 connected to the first adjustment block 2 or the second adjustment block 3; the adjustment handle 43 is connected to the driving bevel gear 42 and is freely passed through the outside of the protective shell 41.

[0021] The protective shell 41 provides installation space for the driving bevel gear 42 and the driven bevel gear 44, so that the driving bevel gear 42 and the driven bevel gear 44 can be stably matched within the protective shell 41, and at the same time supports the adjustment handle 43. The adjustment handle 43 is held at one end outside the protective shell 41 and rotated to drive the driving bevel gear 42 to rotate. The driving bevel gear 42 drives the driven bevel gear 44, which in turn drives the first adjustment block 2 or the second adjustment block 3 connected thereto to rotate, thereby completing the adjustment of the injection hole. Among them, the driven bevel gear 44 is connected to the first adjustment block 2 or the second adjustment block 3 by a connecting shaft for transmission.

[0022] In order to keep the injection hole stable after adjustment, so as to facilitate the stable positioning of the syringe needle; Figure 2 As shown, according to another embodiment of the present invention, the maxillofacial injection positioner for plastic surgery is provided, wherein the adjustment handle 43 is provided with an adjustable locking assembly 5 .

[0023] When rotating the adjustment handle 43, first release the lock of the adjustment handle 43 by the adjustable locking assembly 5, and then the adjustment handle 43 can be rotated; after the adjustment is completed, adjust the adjustable locking assembly 5 to lock the adjustment handle 43, thereby completing the locking of the active bevel gear 42, the driven bevel gear 44 and the first adjustment block 2 or the second adjustment block 3 to ensure that the injection hole maintains the adjusted position to meet the usage requirements.

[0024] Based on the above scheme:

[0025] The adjustable locking assembly 5 includes a mounting block 51 and an adjusting screw 52; wherein, the mounting block 51 is fixedly arranged on the outer wall of the protective shell 41; the adjusting screw 52 is threadedly connected to the mounting block 51 and one end of which is connected to a pressing block 53 arranged toward the side wall of the adjusting handle 43.

[0026] Here, the mounting block 51 supports the adjusting screw rod 52, and the adjusting screw rod 52 is rotated to move the pressing block 53 toward the adjusting handle 43 until the pressing block 53 abuts against the adjusting handle 43, thereby completing the locking of the adjusting handle 43; the adjusting screw rod 52 is rotated in the opposite direction to move the pressing block 53 away from the adjusting handle 43, and the pressing block 53 disengages from the abutment against the adjusting handle 43, thereby unlocking the adjusting handle 43.

[0027] Because the adjustment handle 43 is cylindrical, the pressing block 53 is designed as an arc-shaped block. The pressing block 53 is rotatably connected to the adjustment screw 52. The pressing block 53 is connected to a guide rod 54 that is slidably connected to the mounting block 51. The guide rod 54 is arranged parallel to the adjustment screw 52. Here, when the adjustment screw 52 is rotated, the pressing block 53 is guided by the guide rod 54 to move linearly, so that the pressing block 53 fits well against the outer wall of the adjustment handle 43, and there is a large contact area between the pressing block 53 and the adjustment handle 43, ensuring that the adjustment handle 43 is locked stably.

[0028] Because the maxillofacial fitting mask 1 can be a disposable product, in order to reduce the use cost, such as Figure 1 As shown, according to another embodiment of the present invention, a maxillofacial injection positioner for plastic surgery is provided, wherein the maxillofacial fitting cover 1 is provided with an assembly hole, a detachable connecting block 6 is embedded in the assembly hole, and the first adjustment block 2 is arranged on the connecting block 6.

[0029] Specifically, a plurality of connecting ears are formed circumferentially on the connecting block 6. When the connecting block 6 is embedded in the assembly hole, the connecting ears overlap the outer side of the maxillofacial fitting cover 1, and each connecting ear can be connected to the maxillofacial fitting cover 1 by a screw; after use, the connecting block 6 can be disassembled, so that the connecting block 6, the first adjustment block 2 and the second adjustment block 3 can be combined to form a reusable product to reduce the cost of use; after each use, the connecting block 6, the first adjustment block 2 and the second adjustment block 3 need to be thoroughly disinfected before use, and during use, only the maxillofacial fitting cover 1 will come into contact with the user's face, and the connecting block 6, the first adjustment block 2 and the second adjustment block 3 will not come into contact with the user's face.

[0030] Among them, connecting holes are formed in the middle of the connecting block 6 and the middle of the first adjustment block. The first adjustment block 2 is rotatably set in the connecting hole in the middle of the connecting block 6, and the second adjustment block 3 is rotatably set in the connecting hole in the middle of the first adjustment block.

[0031] It is worth noting that:

[0032] The angle adjustment of the syringe needle during use is relatively small, so the angle adjustment of the injection hole is relatively small, and thus the rotation angle of the first adjustment block 2 and the second adjustment block 3 is relatively small. The first adjustment block 2 and the second adjustment block 3 generally do not contact the user's face during rotation.

[0033] In order to improve the safety of use, Figure 1 As shown, according to another embodiment of the present invention, a disposable positioning sleeve 7 is tightened in the injection hole of the plastic surgery and cosmetic maxillofacial injection positioner. To prevent the syringe needle from penetrating into the injection hole and causing contamination, the disposable positioning sleeve 7 is removed after each use and replaced with a new disposable positioning sleeve 7 before the next use, thereby improving safety.

[0034] When using:

[0035] Wear the maxillofacial fitting mask 1 on the user's face. When it is necessary to rotate the first adjustment block 2 and / or the second adjustment block 3, first rotate the corresponding adjustment screw 52 to unlock the corresponding adjustment handle 43, and then rotate the corresponding adjustment handle 43 to rotate the first adjustment block 2 and / or the second adjustment block 3; after completing the adjustment, rotate the corresponding adjustment screw 52 again to lock the corresponding adjustment handle 43 again; at this time, the needle of the syringe can be passed through the disposable positioning sleeve 7 for precise needle insertion.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
