Description

Technical Field

[0001] This application relates to the field of medical device technology, and more particularly to a standardized rotating imaging stand for facial surgery. Background Technology

[0002] In clinical practice of plastic surgery, pre- and post-operative photographs are extremely important medical records. They are used for surgical planning, efficacy evaluation, academic exchange, and medical legal evidence. Because common tripods or selfie sticks only offer simple fixation and height adjustment, they cannot control the rotation angle of the patient's head, let alone guide the photographing equipment to move precisely around the head. Some industrial rotating platforms are completely unsuitable for the medical environment and lack a design that coordinates with head positioning. Therefore, when taking pre- and post-operative photos, doctors or nurses typically use handheld mobile phones or cameras.

[0003] However, the shooting distance, angle, focal length, and lighting conditions all depend on the operator's experience and intuition, making it difficult to ensure consistent parameters for each shot. This results in a lack of comparability between pre- and post-operative photos, making it difficult to objectively reflect subtle improvements. To comprehensively assess facial contours, multiple fixed angles are required, including frontal, bilateral 90-degree side, bilateral 45-degree oblique, and mandibular angle views. Handheld shooting makes it difficult to accurately reproduce the exact same angles and compositions each time, especially ensuring the head remains stable without rotation or tilt. Taking a complete set of multi-angle facial photographs requires repeated adjustments to the patient's position and shooting location, a cumbersome process that consumes valuable time for medical staff.

[0004] Therefore, the aforementioned technical deficiencies urgently need to be addressed. Summary of the Invention

The connecting bracket is movably connected to the front end of the neck glove body through the movable shaft. And a shooting device, which is set on the connecting bracket at one end away from the neck brace body; The connecting bracket is equipped with a level and a distance sensor.

[0007] In one possible implementation, the neck collar body includes: Auxiliary neck brace, an auxiliary neck brace is used to be worn around the patient's neck; And a chin support, which is movably connected to the auxiliary neck brace. The chin support is used to support the patient's chin. A movable mechanism is provided between the chin support and the auxiliary neck brace. The movable mechanism is used to adjust the pitch angle and height of the chin support. The connecting bracket is movably connected to the front end of the auxiliary neck brace. A horizontal laser emitter is provided on the connecting bracket near the shooting device. The horizontal laser emitter faces the chin support. A calibration and positioning part is provided on the chin support facing the horizontal laser emitter.

An angle marking disk is provided on the front end of the auxiliary neck sleeve, and the angle marking disk is arranged around the outer circumference of the movable shaft. The angle marking disk is used to mark the rotation angle of the connecting bracket in the horizontal direction.

[0009] In one possible implementation, the connecting bracket includes a telescopic section with several length markers on it. The length markers are used to mark the telescopic length of the telescopic section, and the telescopic section is used to adjust the length of the connecting bracket.

[0011] In one possible implementation, the auxiliary neck brace is provided with a front chest abutment and a rear neck support, and the movable axis is located on the front chest abutment.

[0012] In one possible implementation, the posterior neck support has an arc-shaped abutment surface on the side closest to the back of the patient's neck, which is used to support the back of the patient's neck.

[0013] In one possible implementation, a cushioning airbag is provided on the jaw support for supporting the patient's jaw, and the cushioning airbag is positioned along the extension direction of the upper end face of the jaw support.

[0014] In one possible implementation, a pressure sensor is installed inside the airbag to detect the air pressure inside the airbag.

[0015] In one possible implementation, a buffer layer is provided at the end of the auxiliary neck brace opposite to the chin support, and the buffer layer extends along the extension direction of the auxiliary neck brace.

[0016] Compared with existing technologies, this application provides a standardized rotating imaging stand for the face in plastic surgery. In use, the neck collar is first placed around the patient's neck. The neck collar and the connecting stand are adjusted and calibrated using a level and distance sensor to ensure the patient's head is at a standard angle and position.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0022] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" 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 between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0023] Furthermore, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0024] This invention provides, for example Figure 1 , Figure 2As shown, a standardized rotating imaging stand for facial surgery is designed to be worn around a patient's neck, positioning the patient's head at a standard angle and position. This allows the imaging device 3 to move horizontally around the patient's head accurately, capturing photos or videos from different angles for surgical planning, efficacy evaluation, academic exchange, and medical legal evidence. The main structure includes: a neck collar body 1, a connecting bracket 2, and the imaging device 3. The neck collar body 1 is worn around the patient's neck, fixing the patient's head at a standard position and angle. A movable shaft 21 is located at one end of the connecting bracket 2 near the neck collar body 1. The axis of the movable shaft 21 extends along a first direction, which is the height direction of the neck collar body 1. The connecting bracket 2 is movably connected to the front end of the neck collar body 1 via the movable shaft 21. The imaging device 3 is located at the end of the connecting bracket 2 opposite to the neck collar body 1, allowing the connecting bracket 2 to rotate horizontally around the movable shaft 21, thus enabling the imaging device 3 to capture photos or videos of the patient's face from different angles.

[0025] The connecting bracket 2 is equipped with a level 22 and a distance sensor 23. The level 22 measures the horizontal angle of the connecting bracket 2. Medical staff can adjust the horizontal state of the connecting bracket 2 by observing the level 22, avoiding excessive angular deviations in the position of pre- and post-operative photos taken by the patient due to large tilting of the connecting bracket 2, which would ultimately affect the accuracy of photo evaluation. The distance sensor 23 measures the vertical distance between the connecting bracket 2 and the ground. In some embodiments, the distance sensor 23 can be a laser distance sensor 23. The laser distance sensor 23 emits a laser beam perpendicularly to the ground to measure the vertical distance between the connecting bracket 2 and the ground. It is understood that the specific functions of the distance sensor 23 and the level 22 in this embodiment are known to those skilled in the art based on existing technology, and the structure and working principle of the distance sensor 23 and the level 22 will not be described in detail here.

[0026] It's important to note that in traditional facial imaging, the shooting distance, angle, focal length, and lighting conditions all rely on the operator's experience and intuition, making it difficult to ensure consistent parameters for each shot. This results in a lack of comparability between pre- and post-operative photos, making it difficult to objectively reflect subtle improvements. To comprehensively assess facial contours, multiple fixed angles are required, including frontal, bilateral 90-degree side, bilateral 45-degree oblique, and mandibular angle views. Handheld shooting makes it difficult to accurately reproduce the exact same angles and compositions each time, especially ensuring the head remains stable without rotation or tilt. Taking a complete set of multi-angle facial photographs requires repeated adjustments to the patient's position and shooting location, a cumbersome process that consumes valuable time for medical staff.

[0027] In use, the neck brace body 1 is first placed around the patient's neck. The neck brace body 1 and the connecting bracket 2 are then adjusted and calibrated using a level 22 and a distance sensor 23 on the connecting bracket 2. Medical personnel can observe the level 22 to adjust the horizontal position of the connecting bracket 2, preventing excessive angular deviations in the position of pre- and post-operative photos taken due to significant tilting of the connecting bracket 2, which would ultimately affect the accuracy of photo evaluation.

[0028] It is important to note that because patients have different heights, the height data measured by the distance sensor 23 will vary. Therefore, the distance data between the connecting bracket 2 and the ground measured for the same patient before surgery needs to be recorded and archived. When the patient needs to take postoperative photos or videos, the distance between the connecting bracket 2 and the ground needs to be adjusted to the initial distance data. This ensures that the patient's head is in a standard position and angle before and after surgery. Then, by moving the connecting bracket 2, the imaging device 3 can take photos or videos around the patient's head at different positions. This allows for a standard comparison of the patient's face before and after surgery, avoiding discrepancies in the photos and videos taken before and after surgery due to deviations in the position and angle of the connecting bracket 2, which could ultimately lead to inaccurate preoperative and postoperative assessments.

[0029] Furthermore, such as Figure 1 , Figure 3 As shown, the neck brace body 1 includes: an auxiliary neck brace 11 and a chin support 12. The auxiliary neck brace 11 is worn on the patient's neck. The chin support 12 is movably connected to the auxiliary neck brace 11 and is used to support the patient's chin. An active mechanism 13 is provided between the chin support 12 and the auxiliary neck brace 11. The active mechanism 13 is used to adjust the tilt angle and height of the chin support 12. The connecting bracket 2 is movably connected to the front end of the auxiliary neck brace 11. A horizontal laser emitter 24 is provided on the connecting bracket 2 near the shooting device 3. The horizontal laser emitter 24 faces the chin support 12. A calibration and positioning part 121 is provided on the chin support 12 facing the horizontal laser emitter 24. The horizontal laser emitter 24 is used to emit a horizontal laser beam toward the calibration and positioning part 121.

[0030] Understandably, the laser beam emitted by the horizontal laser emitter 24 facilitates the calibration of the jaw support 12 by medical personnel. During calibration, medical personnel need to adjust the negative pressure angle box height of the jaw support 12 via the movable mechanism 13, thereby ensuring that the laser beam emitted by the horizontal laser emitter 24 irradiates the calibration positioning part 121 on the jaw support 12. Ultimately, this allows the patient's jaw to rest against the jaw support 12, and the patient's head to maintain a standard position and angle. The specific function of the horizontal laser emitter 24 in this embodiment is readily apparent to those skilled in the art based on existing technology; therefore, the structure and working principle of the horizontal laser emitter 24 will not be elaborated upon here.

[0031] Furthermore, such as Figure 1 , Figure 4 As shown, the connecting bracket 2 is movably connected to the front end of the auxiliary neck brace 11 via a movable shaft 21. An angle marker disk 111 is mounted on the front end of the auxiliary neck brace 11, surrounding the outer circumference of the movable shaft 21. The angle marker disk 111 is used to mark the rotation angle of the connecting bracket 2 in the horizontal direction. Since the imaging device 3 needs to capture images of the patient at different angles in the horizontal direction during the imaging process, the angle marker disk 111 allows medical personnel to visually monitor the movement of the connecting bracket 2 as it swings horizontally. This improves the efficiency of the imaging operation.

[0032] Furthermore, such as Figure 2 As shown, the connecting stent 2 includes a telescopic section 25 with several length markers 251. These markers indicate the telescopic length of the section 25, which is used to adjust the length of the connecting stent 2. The connecting stent 2 achieves length adjustment through the telescopic section 25. However, to ensure the consistency of pre- and post-operative photos and videos, the length of the connecting stent 2 must remain consistent during these procedures. Medical staff can record the length markers 251 on the connecting stent 2 before surgery to ensure consistent length adjustment later.

[0033] Furthermore, such as Figure 1 , Figure 2As shown, a horizontal lifting mechanism 26 is provided on the connecting bracket 2, which is used to adjust the height of the connecting bracket 2. In this embodiment, the horizontal lifting mechanism 26 includes at least two parallel connecting members 261. The at least two parallel connecting members 261 are arranged in parallel. Both ends of the parallel connecting members 261 are movably connected to the connecting bracket 2 and the movable shaft 21, respectively. The hinged relationship between the two parallel connecting members 261 allows the connecting bracket 2 to be raised and lowered horizontally. It should be noted that when the connecting bracket 2 is raised or lowered, the parallel connecting members 261 will swing, and the angle between the parallel connecting members 261 and the connecting bracket 2 will change. To ensure that the position angle of the patient's preoperative and postoperative photos and videos remains consistent, the angle between the parallel connecting members 261 and the connecting bracket 2 needs to be recorded when the connecting bracket 2 is adjusted preoperatively. To facilitate recording the angle between the parallel connecting members 261 and the connecting bracket 2, in some embodiments, an angle dial can be provided on the movable shaft 21 between the connecting bracket 2 and the parallel connecting members 261, so that medical personnel can read the angle between them.

[0034] Furthermore, such as Figure 3 As shown, the auxiliary neck brace 11 is provided with a front chest abutment part 112 and a rear neck support part 113, and the movable shaft 21 is provided on the front chest abutment part 112.

[0035] Furthermore, such as Figure 3 As shown, the posterior neck support 113 has an arc-shaped abutment surface 114 on the side near the back of the patient's neck, which is used to support the back of the patient's neck.

[0036] Furthermore, such as Figure 3 As shown, a cushioning airbag 122 is provided on the jaw support 12. The cushioning airbag 122 is used to support the patient's jaw and is arranged along the extension direction of the upper end face of the jaw support 12. This allows different parts of the patient's jaw to directly abut against the cushioning airbag 122, improving the contact effect between the patient's jaw and the jaw support 12, thereby improving the wearing comfort of the device. It is understood that the cushioning airbag 122 can improve the contact effect between the patient's jaw and the jaw support 12, thereby improving the wearing comfort of the device.

[0037] Furthermore, such as Figure 3 As shown, a pressure sensor 1221 is installed inside the air cushion 122 to detect the air pressure value inside the air cushion 122. During use, the patient's chin rests against the air cushion 122 on the chin support 12. The air cushion 122 improves the patient's comfort during cervical spine correction. Furthermore, the pressure sensor detects the pressure of the air cushion 122, and an alarm signal is issued when the pressure value exceeds a preset pressure threshold, allowing medical personnel to make timely adjustments and avoid harm to the patient.

[0038] Furthermore, such as Figure 3 As shown, a buffer layer 115 is provided at one end of the auxiliary neck brace 11 away from the chin support 12, and the buffer layer 115 extends along the extending direction of the auxiliary neck brace 11. Similar to the buffer airbag 122 described above, in this embodiment, the buffer layer 115 can abut against the patient's skin, increasing the contact area between the auxiliary neck brace 11 and the patient's skin, thereby effectively improving the comfort of the auxiliary neck brace 11.

[0039] In summary, this application provides a standardized rotating imaging stand for the face in plastic surgery. In use, the neck collar 1 is first placed around the patient's neck. The neck collar 1 and the connecting stand 2 are adjusted and calibrated using a level 22 and a distance sensor 23 on the connecting stand 2 to ensure the patient's head is at a standard angle and position. Then, by moving the connecting stand 2, the imaging device 3 takes photos or videos around the patient's head at different positions. This allows for the acquisition of standard pre- and post-operative comparison photos or videos of the patient's face.

[0040] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
