Description

Technical Field

[0001] This utility model belongs to the field of facial plastic surgery technology, specifically relating to a fixator for facial plastic surgery. Background Technology

[0002] Facial plastic surgery demands extremely precise fixation of the patient's position during the procedure. With the increasing sophistication of facial plastic surgery techniques, fixators need to combine flexibility and stability to adapt to the dynamic head positioning requirements during delicate procedures on areas such as the nose and cheekbones. Traditional facial plastic surgery often relies on head supports, straps, or general fixation devices. However, these tools cannot simultaneously meet the needs of multi-angle adjustment, head shape adaptation, and patient comfort during surgery. They are limited in function and cannot take into account multi-dimensional head adjustment. These problems directly lead to low fixation efficiency during surgery, and it is difficult to guarantee patient comfort and safety. Utility Model Content

[0003] In view of this, the present invention provides a fixator for facial plastic surgery, which can adjust the angle of the patient's head according to different surgical needs through the coordinated cooperation of the fixing mechanism and the rotating component. It can flexibly adjust the spacing and clamping force according to the patient's head shape to achieve rapid fixation of the patient's head, significantly improve the convenience of operation for medical staff and the comfort of patients, and greatly improve the effect of facial plastic surgery.

[0004] To address the aforementioned technical problems, this utility model provides a facial plastic surgery fixator, comprising a fixation bracket and a fixation mechanism mounted thereon. The fixation mechanism includes a rotating mounting frame rotatably connected to the inner side of the upper end of the fixation bracket. A rotating assembly for driving the rotating mounting frame to rotate is also provided on the outer side of the upper end of the fixation bracket. A positioning headrest is provided at the bottom of the rotating mounting frame, and fixing rods are provided on both sides of the positioning headrest. Sliding sleeves are slidably connected to the fixing rods, and rectangular rods are slidably connected to the upper ends of the sliding sleeves. Positioning plates are provided on the opposite inner sides of the two rectangular rods, and the positioning plates are inverted L-shaped. A support member is also provided at the bottom of the fixation bracket to provide support for the positioning headrest. This allows for flexible adjustment of the spacing and clamping force according to the patient's head shape, achieving rapid fixation of the patient's head. The angle of the patient's head can be adjusted according to different surgical needs, significantly improving the convenience of operation for medical staff and the comfort of the patient, greatly enhancing the effect of facial plastic surgery.

[0005] The fixing mechanism also includes rotating sleeves that are rotatably connected to the outer side of the upper end of the rectangular rod. Each rotating sleeve is equipped with a lead screw, the axis of which coincides with the axis of the rotating sleeve. The lead screws are threadedly connected to the threaded holes on the adjacent rectangular rods on the same side, thus achieving the function of left and right displacement.

[0006] The fixing mechanism also includes threaded rods that are rotatably connected to the lower end of the fixing rod. The threaded rods are threadedly connected to threaded holes on the adjacent sliding sleeves on the same side, which enables them to move up and down.

[0007] The fixing mechanism also includes rubber pads installed in the positioning plate, which serve as a buffer.

[0008] The rotating assembly includes a worm gear located on the outer end of the upper part of the rotating mounting bracket. The upper outer part of the fixed bracket is provided with symmetrically distributed assembly blocks. A worm is rotatably connected between the two assembly blocks. The worm and the worm gear are meshed and connected, which not only achieves rotation but also utilizes the self-locking property of the two meshing to achieve a self-locking effect.

[0009] The support includes an arc-shaped guide rail located at the lower end of the positioning headrest. The center of the circle containing the arc-shaped guide rail coincides with the rotation axis of the rotating mounting bracket. The bottom of the fixed bracket is provided with a guide seat that is slidably connected to the arc-shaped guide rail, thus ensuring that the head rotates stably along a predetermined arc trajectory.

[0010] The upper outer side of the fixed bracket is equipped with a protective cover. The worm gear, assembly block and worm are all located inside the protective cover. Both ends of the protective cover are equipped with through holes that match the ends of the worm, which prevents contamination and ensures operational safety.

[0011] The beneficial effects of the above-mentioned technical solution of this utility model are as follows: 1. Medical staff fix the fixation bracket and its auxiliary mechanisms in the designated position on the facial plastic surgery table. When it is necessary to fix the patient's head, the patient's head is placed on the positioning headrest. Then, the medical staff rotate the rotating sleeve and the threaded rod in sequence. When the rotating sleeve rotates, the threaded rod inside rotates synchronously. Utilizing the influence of its connection with the threaded hole, it drives the rectangular rod, positioning plate, and rubber pad to move towards the patient's head, thereby fixing both sides of the patient's head. Subsequently, the threaded rod rotates, and the influence of the threaded connection between the threaded rod and the threaded hole drives the sliding sleeve and its auxiliary mechanisms to move downward, so that the positioning plate contacts the patient's forehead. The spacing and clamping force can be flexibly adjusted according to the patient's head shape to achieve rapid fixation of the patient's head. At the same time, the rubber pad effectively buffers the pressure. Then, the medical staff drives the rotating mounting bracket and the patient's head to rotate through the rotating components. It is possible to adjust the angle of the patient's head according to different surgical needs, significantly improving the convenience of operation for medical staff and the comfort of patients, and greatly improving the effect of facial plastic surgery.

[0012] 2. Medical staff rotate the worm gear, which, through the meshing transmission between the worm gear and the worm wheel, drives the rotating mounting frame and the patient's head to rotate, allowing the angle of the patient's head to be adjusted according to different surgical needs.

[0013] 3. The worm gear, worm shaft and other transmission components are covered by a protective cover to prevent contamination and ensure operational safety.

[0014] 4. The arc-shaped guide rail at the lower end of the positioning headrest cooperates with the guide seat at the bottom of the fixed bracket to ensure that it rotates stably along the predetermined arc trajectory. Attached Figure Description

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0018] This embodiment provides a fixator for facial plastic surgery, such as... Figure 1-4The system includes a fixed bracket 100 and a fixing mechanism mounted thereon. The fixing mechanism includes a rotating mounting bracket 200 rotatably connected to the inner side of the upper end of the fixed bracket 100. The rotating mounting bracket 200 is L-shaped. A rotating component for driving the rotating mounting bracket 200 to rotate is also provided on the outer side of the upper end of the fixed bracket 100. A positioning headrest 201 is provided at the bottom of the rotating mounting bracket 200. The upper end of the positioning headrest 201 conforms to the contour of the human head and is made of rubber to relieve patient discomfort. Fixing rods 202 are provided on both sides of the positioning headrest 201. The fixing rods 202 are L-shaped. Sliding sleeves 203 are slidably connected to the fixing rods 202. Rectangular rods 204 are slidably connected to the upper ends of the sliding sleeves 203. The inner sides of the two rectangular rods 204 are... Each surface is provided with a positioning plate 205, which is inverted L-shaped. The bottom of the fixed bracket 100 is also provided with a support member for supporting the positioning headrest 201. The fixing mechanism also includes a rotating sleeve 206 rotatably connected to the outer side of the upper end of the rectangular rod 204. Each rotating sleeve 206 is provided with a lead screw 207. The axis of the lead screw 207 coincides with the axis of the rotating sleeve 206 on which it is located. The lead screw 207 is threadedly connected to the threaded hole provided on the adjacent rectangular rod 204 on the same side. The fixing mechanism also includes a threaded rod 208 rotatably connected to the lower end of the fixed rod 202. The threaded rod 208 is threadedly connected to the threaded hole provided on the adjacent sliding sleeve 203 on the same side. The fixing mechanism also includes rubber pads 209 respectively provided in the positioning plate 205.

[0019] Medical staff fix the fixation bracket 100 and its auxiliary mechanisms in the designated position on the facial plastic surgery table. When it is necessary to fix the patient's head, the patient's head is placed on the positioning headrest 201. Then, the medical staff rotate the rotating sleeve 206 and the threaded rod 208 in sequence. When the rotating sleeve 206 rotates, the threaded rod 207 inside it rotates synchronously. Utilizing the influence of its connection with the threaded hole, it drives the rectangular rod 204, the positioning plate 205, and the rubber pad 209 to move towards the patient's head, thereby achieving fixation of both sides of the patient's head. Subsequently, the threaded rod 208 rotates, driven by... The threaded connection between the threaded rod 208 and the threaded hole drives the sliding sleeve 203 and its auxiliary mechanism to move downwards, thereby allowing the positioning plate 205 to contact the patient's forehead. The spacing and clamping force can be flexibly adjusted according to the patient's head shape to achieve rapid fixation of the patient's head. At the same time, the rubber pad 209 effectively buffers the pressure. Subsequently, medical staff drive the rotating mounting bracket 200 and the patient's head to rotate through the rotating component. The angle of the patient's head can be adjusted according to different surgical needs, significantly improving the convenience of operation for medical staff and the comfort of patients, and greatly improving the effect of facial plastic surgery.

[0020] like Figure 1-4As shown, the rotating assembly includes a worm gear 300 disposed on the outer end of the upper end of the rotating mounting bracket 200, and symmetrically distributed assembly blocks 301 on the outer end of the upper end of the fixed bracket 100. A worm 302 is rotatably connected between the two assembly blocks 301, and the worm 302 is meshed with the worm gear 300.

[0021] Subsequently, medical staff rotate the worm gear 302. Through the meshing transmission between the worm gear 302 and the worm wheel 300, the rotating mounting frame 200 and the patient's head are driven to rotate, which can adjust the angle of the patient's head according to different surgical needs.

[0022] like Figure 1-2 As shown, the support includes an arc-shaped guide rail 400 disposed at the lower end of the positioning headrest 201. The center of the circle containing the arc-shaped guide rail 400 coincides with the rotation axis of the rotating mounting bracket 200. The bottom of the fixed bracket 100 is provided with a guide seat 401 that is slidably connected to the arc-shaped guide rail 400.

[0023] The arc-shaped guide rail 400 at the lower end of the positioning headrest 201 cooperates with the guide seat 401 at the bottom of the fixed bracket 100 to ensure that it rotates stably along the predetermined arc trajectory.

[0024] like Figure 1-4 As shown, a protective cover 500 is provided on the outer side of the upper end of the fixed bracket 100. The worm gear 300, the assembly block 301 and the worm 302 are all located inside the protective cover 500. Both ends of the protective cover 500 are provided with through holes that are compatible with the two ends of the worm 302.

[0025] The transmission components, such as the worm gear 300 and worm 302, are enclosed by a protective cover 500, which prevents contamination and ensures operational safety.

[0026] The working principle of the facial plastic surgery fixator provided by this utility model is as follows: First, medical staff fix the fixation bracket 100 and its auxiliary mechanisms in a designated position on the facial plastic surgery table. When it is necessary to fix the patient's head, the patient's head is placed on the positioning headrest 201. Then, the medical staff rotates the rotating sleeve 206 and the threaded rod 208 in sequence. When the rotating sleeve 206 rotates, the threaded rod 207 inside it rotates synchronously. Utilizing the influence of its threaded connection with the threaded hole, it drives the rectangular rod 204, the positioning plate 205, and the rubber pad 209 to move towards the patient's head, thereby achieving fixation of both sides of the patient's head. Subsequently, the threaded rod 208 rotates, and the influence of the threaded connection between the threaded rod 208 and the threaded hole drives the sliding sleeve 203 and its auxiliary mechanisms to move downward, thereby causing the positioning plate 204 to move downward. 5. The device contacts the patient's forehead and can flexibly adjust the spacing and clamping force according to the patient's head shape to quickly fix the patient's head. At the same time, the rubber pad 209 effectively buffers the pressure. Then, the medical staff rotates the worm gear 302. The meshing transmission between the worm gear 302 and the worm wheel 300 drives the rotating mounting frame 200 and the patient's head to rotate. At the same time, the arc-shaped guide rail 400 at the lower end of the positioning headrest 201 cooperates with the guide seat 401 at the bottom of the fixed bracket 100 to ensure stable rotation along the predetermined arc trajectory. The angle of the patient's head can be adjusted according to different surgical needs, which significantly improves the convenience of operation for medical staff and the comfort of patients, and greatly improves the effect of facial plastic surgery. In addition, the transmission components such as the worm wheel 300 and worm gear 302 are wrapped by the protective cover 500, which not only prevents contamination but also ensures operational safety.

[0027] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
