Description

Technical Field

[0001] The present invention belongs to the field of surgical instruments, and more specifically, it is a fixator for microplastic injection and shaping. Background Art

[0002] Microplastic injection and shaping is a cosmetic method. Its basic principle is to directly increase the subcutaneous tissue volume by injecting and filling the dermis layer, thereby achieving a bulging effect, and it may stimulate the proliferation of collagen and lock in the skin moisture.

[0003] During the process of microplastic injection and shaping, especially for injections in facial areas such as the forehead, precise positioning of the injection site is required. Head fixation can ensure that the patient maintains a stable posture during the injection process, thus helping the doctor to more accurately find the injection point and improve the injection accuracy. This helps to avoid injection deviation, ensure that the filler can be evenly distributed in the target area, and achieve the ideal shaping effect.

[0004] However, traditional strap fixators cannot provide sufficient firmness, especially in microplastic injection and shaping surgeries that require maintaining a fixed posture for a long time. Summary of the Invention

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0043] As Figures 1 to 5 shown:

[0044] Embodiment 1: The present invention provides a fixator for microplastic injection shaping, including a support mechanism 1 and a clamping mechanism 2;

[0045] The support mechanism 1 includes a support plate assembly 11, and a driving assembly 12 is installed inside the support plate assembly 11;

[0046] The clamping mechanism 2 includes a first clamping assembly 21 and a second clamping assembly 22 that are slidably arranged on the support plate assembly 11;

[0047] The driving assembly 12 drives the first clamping assembly 21 and the second clamping assembly 22 to move relatively;

[0048] Among them, when in use, the device is placed at the head position of the support bed 4. When performing injection shaping, the user lies on the support bed 4. Controlling the driving assembly 12 to work can drive the first clamping assembly 21 and the second clamping assembly 22 to move relatively and clamp the user's head, achieving the function of limiting and fixing the user's head.

[0049] Specifically, the support plate assembly 11 includes a support plate body 111. A headrest 112 is fixedly connected to the middle position of the support plate body 111. Guide rods 113 are also fixedly connected to both sides of the support plate body 111 where the guide rods 113 are located.

[0050] Specifically, the drive assembly 12 includes a bidirectional lead screw 121 and a motor 122. A worm gear 123 is fixedly connected to the outer side of the bidirectional lead screw 121. A worm 124 is fixedly connected to the output end of the motor 122;

[0051] The bidirectional lead screw 121 is installed inside the support plate body 111 through bearings. The motor 122 is fixedly installed at the bottom of the support plate body 111. The worm gear 123 and the worm 124 mesh with each other;

[0052] The first clamping assembly 21 and the second clamping assembly 22 are symmetrically arranged on the support plate body 111 and are driven by the bidirectional lead screw 121.

[0053] As can be seen from the above, after the user's head rests on the headrest 112, the motor 122 is controlled to start, driving the worm 124 to rotate, and then driving the worm gear 123 to engage and drive, so that the bidirectional lead screw 121 rotates inside the support plate body 111; this rotation action drives the first clamping assembly 21 and the second clamping assembly 22 to move symmetrically on the support plate body 111 through the bidirectional lead screw 121, realizing the clamping or releasing action of the user's head.

[0054] As Figure 6 and 7 shown:

[0055] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the first clamping assembly 21 includes a first slider 211, a first head clamping block 212 and a first mandible clamping block 213. A first soft pad 214 is fixedly connected to the middle position on the upper side of the first slider 211. First limiting rods 215 are fixedly connected to both ends on the upper side of the first slider 211;

[0056] The first head clamping block 212 and the first mandible clamping block 213 are both rotationally and limitingly clamped on the first limiting rods 215;

[0057] The second clamping assembly 22 includes a second slider 221, a second head clamping block 222 and a second mandible clamping block 223. A second soft pad 224 is fixedly connected to the middle position on the upper side of the second slider 221. Second limiting rods 225 are fixedly connected to both ends on the upper side of the second slider 221;

[0058] The second head clamping block 222 and the second mandible clamping block 223 are both rotationally and limitingly clamped on the second limiting rods 225.

[0059] Specifically, a limiting buckle 114 is also fixedly connected to the outer side of the support plate body 111.

[0060] Specifically, straps 216 are fixedly connected to the outer sides of the first head clamping block 212 and the first lower jaw clamping block 213, and straps 226 are fixedly connected to the second head clamping block 222 and the second lower jaw clamping block 223;

[0061] The strap 216 and the strap 226 are snap-connected.

[0062] As can be seen from the above, during operation, the first clamping assembly 21 and the second clamping assembly 22 move towards the middle respectively under the drive of the bidirectional lead screw 121; the first slider 211 and the second slider 221 slide along the guiding structure on the support plate body 111, and at the same time, the first soft pad 214 and the second soft pad 224 provide buffering;

[0063] The first head clamping block 212, the first lower jaw clamping block 213, the second head clamping block 222, and the second lower jaw clamping block 223 are all limited in rotation by the first limiting rod 215 and the second limiting rod 225 to adapt to different head shapes;

[0064] When the two groups of clamping assemblies reach the appropriate positions, the head clamping block and the lower jaw clamping block are snap-connected by the strap 216 and the strap 226 to fix the head;

[0065] The support plate body 111 can be more conveniently clamped and placed on the support bed 4 through the limiting buckle 114 on the outside.

[0066] Such as Figure 8 and Figure 9 shown:

[0067] Embodiment 3: This embodiment is basically the same as the previous embodiment, the difference being that it further includes a positioning mechanism 3. The positioning mechanism 3 includes a limiting component 31 fixedly installed on the support plate assembly 11, and a set of positioning components 32 are arranged inside the limiting component 31;

[0068] A guiding block 217 is fixedly connected to the outside of the first head clamping block 212, and a guiding block 227 is fixedly connected to the outside of the second head clamping block 222;

[0069] A set of positioning components 32 respectively limit the guiding block 217 and the guiding block 227.

[0070] Specifically, the limiting component 31 includes a limiting frame 311, and an activity groove 312 and a positioning hole 313 are formed on the limiting frame 311;

[0071] The positioning component 32 includes a guiding block 321. A L-shaped bracket 322 is fixedly connected to one side of the guiding block 321. A positioning insertion rod 323 is slidably clamped on the L-shaped bracket 322, and a spring 324 is fixedly connected to the upper end of the positioning insertion rod 323;

[0072] The L-shaped bracket 322 is limited and slidably clamped in the movable groove 312. The spring 324 drives the positioning plug 323 to move downward and embed into the positioning hole 313. A set of guiding blocks 321 respectively limit the guiding block one 217 and the guiding block two 227.

[0073] As can be seen from the above, during operation, driven by the bidirectional lead screw 121, the first clamping assembly 21 and the second clamping assembly 22 move towards the middle. At the same time, the guiding block one 217 and the guiding block two 227 move together with the head clamping block.

[0074] When the guiding block one 217 and the guiding block two 227 respectively contact the guiding block 321, the guiding block one 217 and the guiding block two 227 will deflect and make the head clamping block one 212, the head clamping block two 222 and the user's head fully contact, so as to further limit the user's head.

[0075] When it is necessary to adjust the position of the guiding block 321, control the L-shaped bracket 322 to slide limit in the movable groove 312 of the limit frame 311. The spring 324 drives the positioning plug 323 to move downward and embed into the corresponding positioning hole 313. By embedding the positioning plug 323 into different positioning holes 313, it is convenient for the staff to appropriately adjust the position of the guiding block 321 according to the user's head condition.
