Description

Technical Field

[0001] This invention relates to the field of medical devices, specifically to a universal measuring platform for preoperative facial minimally invasive surgery. Background Technology

[0002] Before facial minimally invasive cosmetic surgery, doctors need to measure the straight-line distance between specific landmarks on the patient's face (such as the distance between the eyes, the distance between the jaw angles, etc.) or the angle between their relative positions (such as the nasofrontal angle, the nasolabial angle, etc.). Based on the measurement results, doctors will assess the proportions of the "three courts and five eyes" and the harmony of the facial features before designing a cosmetic surgery plan.

[0003] Because it is necessary to measure the length or angle of different parts of the face, the traditional method of measurement, which relies on the doctor holding the tool, not only requires the tool to be changed during the measurement process, but is also easily affected by the doctor's skill level and hand stability, especially when the tool cannot provide effective stable support on the face during the measurement. Summary of the Invention

[0004] The purpose of this invention is to provide a universal measuring platform for preoperative facial micro-plastic surgery. This measuring platform can achieve stable measurement of linear distances and angles from the front and side of the patient's face without contact with the patient's face, reducing the requirements for the doctor's skill and hand stability in the measurement operation.

[0005] The technical solution adopted by the present invention to solve the above problems is:

[0006] A universal measuring table for preoperative facial minimally invasive surgery includes:

[0007] A base on which a bracket for head support is fixed;

[0008] Four guide rails are arranged in a rectangular shape on the base, and the guide rails are set perpendicular to the base;

[0009] The bracket has several slide rails between the two guide rails on the front and two sides. The slide rails are perpendicular to the guide rails. The two ends of the slide rails are damped and slidably connected to the two guide rails. Several positioning elements are sleeved on the slide rails and damped and slidably connected. Each positioning element is equipped with a measuring unit. The distance between two adjacent positioning elements on the same slide rail and between two positioning elements on two adjacent slide rails can be measured by the measuring unit.

[0010] As a further limitation of the present invention, the measuring unit includes a rotating component and a connecting component. The rotating component is rotatably connected to the positioning component, and the two can be fixed by a locking mechanism. The rotating component has a hollow structure, and a winding roller is rotatably connected inside its cavity. The inner end of the connecting component and the winding roller are connected by a graduated measuring rope. A torsion spring is provided between the winding roller and the rotating component to apply a force to the winding roller to wind up the measuring rope. A first slot is provided on the rotating component to accommodate the connecting component in the same measuring unit. The first slot is connected to the cavity of the rotating component. A second slot is provided on the rotating component to allow the connecting component in another measuring unit to be inserted and engaged. The first slot and the second slot are arranged at equal angles around the central axis of the rotating component.

[0011] As a further limitation of the present invention, the locking mechanism includes at least four locking pins, each locking pin being integrally connected to the positioning member at an equal angle around the central axis of the rotating member. The rotating member has locking holes corresponding to the locking pins one by one. The positioning member is integrally connected to a connecting shaft. The rotating member is sleeved and rotatably mounted on the connecting shaft and is slidable. A first compression spring is provided between the rotating member and the connecting shaft for applying a force against the positioning member to the rotating member.

[0012] As a further limitation of the present invention, an extension piece is integrally connected to the side of the outer end of the connector. The sides of the first slot and the second slot are both provided with slots for inserting the extension piece. The length of the slot on the second slot is greater than the length of the slot on the first slot. The rotating member is provided with a slot adapted to the extension piece. The slot communicates with the slot on the second slot. A push block is slidably connected in the second slot. A second compression spring is provided between the push block and the rotating member to apply a force to the push block to move out of the second slot.

[0013] As a further limitation of the present invention, the connector includes a main body, a connecting part, and a rotating part. The extension piece is located on the outer end of the main body. One end of the connecting part is rotatably connected to the inner end of the main body. One end of the rotating part is hinged to the other end of the connecting part, and its other end is fixedly connected to the measuring rope. The central axes of the main body, the connecting part, and the rotating part can be on the same straight line. When the connector is engaged in the second slot, the rotation trajectory of one end of the rotating part is tangent to the plane of the end face of the opening of the second slot.

[0014] As a further limitation of the present invention, a transmitter for emitting low-intensity infrared rays is fixed on the inner end of the positioning member, the start switch of the transmitter is located on the top surface of the positioning member, and the measuring unit is located on the outer end of the positioning member and is arranged left and right relative to the slide rail of the transmitter.

[0015] As a further limitation of the present invention, a limiting member is provided horizontally between the two adjacent guide rails to arrange one positioning member on each guide rail in a vertical straight line. The limiting member is provided with a limiting hole for accommodating each positioning member in the same vertical straight line.

[0016] Compared with the prior art, the present invention has the following advantages and effects:

[0017] This invention, through the structural design of the base and guide rail, enables stable measurement of linear distances and angles from the front and sides of the patient's face without contact. It can meet the measurement needs of different cosmetic procedures in facial micro-plastic surgery, and there is no need to change different measuring tools during the facial measurement process. This reduces the requirements for the doctor's skill and hand stability in the measurement operation. At the same time, since the measurement marks can be displayed and preserved intuitively, they can provide doctors with proportional references in the design of subsequent cosmetic surgery plans, and also facilitate doctors to explain the cosmetic surgery plan to patients, thereby improving the persuasiveness of communication.

Detailed Implementation

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0030] See Figures 1-10 This embodiment provides a universal measuring platform for pre-operative facial micro-plastic surgery, comprising a base 1 and four guide rails 2. A bracket 11 for head support is fixed on the base 1. The four guide rails 2 are arranged in a rectangular shape on the base 1 and are perpendicular to the base 1. Several slide rails 21 are provided between the two guide rails 2 on the front and two sides of the bracket 11. The slide rails 21 are perpendicular to the guide rails 2. The two ends of the slide rails 21 are respectively damped and slidably connected to the two guide rails 2. Several positioning elements 3 are sleeved on the slide rails 21 and damped and slidably connected. The positioning elements 3 are provided with measuring units 4. The distance between two adjacent positioning elements 3 on the same slide rail 21 and between two positioning elements 3 on two adjacent slide rails 21 can be measured by the measuring units 4.

[0031] During measurement, the subject's head rests on the bracket 11. Depending on the position on the face to be measured, the positioning piece 3 on the front or side of the base 1 is selected for measurement. Then, depending on the direction of the face measurement, two adjacent positioning pieces 3 on the same slide rail 21 are selected for horizontal measurement, or two positioning pieces 3 on two adjacent slide rails 21 are selected for vertical measurement. Subsequently, along the measurement direction, the two selected positioning pieces 3 are moved horizontally relative to the slide rail 21 until the two positioning pieces 3 are aligned with the two ends of the position to be measured. Finally, the straight-line distance between the two positioning pieces 3 is measured by the measuring unit 4 on the positioning piece 3, thus completing the measurement of the straight-line distance between the two positions on the face.

[0032] See Figures 3-7The measuring unit 4 includes a rotating component 41 and a connecting component 42. The rotating component 41 is rotatably connected to the positioning component 3 and the two can be fixed by a locking mechanism 5. The rotating component 41 has a hollow structure and a winding roller 43 is rotatably connected in its cavity. The inner end of the connecting component 42 and the winding roller 43 are connected by a graduated measuring rope 44. A torsion spring is provided between the winding roller 43 and the rotating component 41 to apply a force to the winding roller 43 to wind up the measuring rope 44. The rotating component 41 has a first slot 61 for accommodating the connecting component 42 in the same measuring unit 4. The first slot 61 is connected to the cavity of the rotating component 41. The rotating component 41 has a second slot 62 for inserting and engaging the connecting component 42 in another measuring unit 4. The first slot 61 and the second slot 62 are arranged at equal angles around the central axis of the rotating component 41.

[0033] The connector 42 includes a main body 45, a connecting part 46, and a rotating part 47. The extension piece 81 is located on the outer end of the main body 45. One end of the connecting part 46 is rotatably connected to the inner end of the main body 45. One end of the rotating part 47 is hinged to the other end of the connecting part 46, and the other end is fixedly connected to the measuring rope 44. The central axes of the main body 45, the connecting part 46, and the rotating part 47 can be on the same straight line. When the connector 42 is engaged in the second slot 62, the rotation trajectory of one end of the rotating part 47 is tangent to the plane of the end face of the opening of the second slot 62.

[0034] When measuring the straight-line distance between two positions on the face, pull out the connector 42 from the first slot 61 of one of the two selected positioning pieces 3, so that the connector 42 pulls out the measuring rope 44 on the winding roller 43. At this time, the torsion spring tightens. Then, insert the connector 42 into the second slot 62 on the other positioning piece 3 on the same side as the first slot 61 from which the connector 42 was pulled out, until the main body 45 of the connector 42 is engaged in the second slot 62. At this time, the rotating part 47 of the connector 42 protrudes from the second slot 62 and is perpendicular to the connecting part 46. Then, rotate the connecting part 46 of the connector 42 relative to the main body 45, so that the rotating part 47 of the connector 42 faces the first slot 61 from which the connector 42 was pulled out. At this time, the length of the measuring rope 44 between the first slot 61 and the second slot 62 is the straight-line distance between the two positioning pieces 3 (e.g., ...). Figure 9 As shown in the figure, the straight-line distance between two positions on the subject's face is measured.

[0035] In the above, if the two positioning elements 3 are located on two slide rails 21 and are staggered, a positioning element 3 on either slide rail 21 can be selected and moved horizontally relative to the slide rail 21 so that the two positioning elements 3 on the two slide rails 21 are on the same vertical line. Then, the horizontal distance between the two positioning elements 3 on the same slide rail 21 or the vertical distance between the two positioning elements 3 on the two slide rails 21 in the same vertical direction is measured by the measurement unit 4 described above. The tilt angle of the measuring rope 44 between the two staggered positioning elements 3 is calculated using trigonometric functions to complete the measurement of the angle between the two positions on the subject's face. Figure 10 As shown in the image.

[0036] See Figure 3 , Figure 4 The inner end of the positioning component 3 is fixed with a transmitter 7 for emitting low-intensity infrared rays. The start switch 71 of the transmitter 7 is located on the top surface of the positioning component 3. The measuring unit 4 is located on the outer end of the positioning component 3 and is arranged to the left and right of the transmitter 7 relative to the slide rail 21. This makes the position alignment between the positioning component 3 and the face of the person being measured visible, which reduces the difficulty of the alignment operation and improves the accuracy of the position alignment.

[0037] See Figure 5 , Figure 6 An extension piece 81 is integrally connected to the outer side of the connector 42, which facilitates the removal of the connector 42 from the first slot 61 and the second slot 62. The sides of the first slot 61 and the second slot 62 are provided with slots 63 for inserting the extension piece 81. The length of the slot 63 on the second slot 62 is greater than the length of the slot 63 on the first slot 61. The rotating member 41 is provided with a slot 64 that matches the extension piece 81. The slot 64 communicates with the slot 63 on the second slot 62. A push block 82 is slidably connected in the second slot 62. A second compression spring 83 is provided between the push block 82 and the rotating member 41 to apply a force to the push block 82 to move it out of the second slot 62. This allows the push block 82 to push the connector 42 to make the extension piece 81 lock in the slot 64, reducing the risk of the connector 42 disengaging from the second slot 62 and thus ensuring the stability of the length of the measuring rope 44 pulled out between the two positioning members 3.

[0038] See Figure 7The locking mechanism 5 includes at least four locking pins 51, the number of which is even. Each locking pin 51 is integrally connected to the positioning member 3 at equal angles around the central axis of the rotating member 41. The rotating member 41 has locking holes 52 corresponding to the locking pins 51. The positioning member 3 is integrally connected to a connecting shaft 53. The rotating member 41 is sleeved and rotatably mounted on the connecting shaft 53 and is slidable. A first compression spring 54 is provided between the rotating member 41 and the connecting shaft 53 to apply a force to the rotating member 41 against the positioning member 3, thereby pulling the rotating member 41... When the relative positioning member 3 slides horizontally, the locking pin 51 can disengage from the locking hole 52, and the locking between the positioning member 3 and the rotating member 41 is released. This allows the positions of the first slot 61 and the second slot 62 on the positioning member 3 to be adjusted synchronously by rotating the rotating member 41 relative to the positioning member 3. This reduces the risk of the rotating member 41 obstructing the measuring rope 44 between the corresponding first slot 61 and second slot 62, and ensures that the pulled-out measuring rope 44 is in a straight state, thereby improving the accuracy of the measuring rope 44 in measuring the straight distance between the two positioning members 3.

[0039] See Figure 8 Each of the two adjacent guide rails 2 is horizontally slidably equipped with a limiting member 9 for arranging a positioning member 3 on each slide rail 21 in a vertical straight line. The limiting member 9 has a limiting hole 91 for accommodating each positioning member 3 on the same vertical line. When the limiting member 9 slides horizontally relative to the base 1, it can drive the positioning members 3 on different slide rails 21 that are on the same straight line to move synchronously and in the same direction. While realizing the change of the position of the positioning member 3, it also ensures that the vertical arrangement of the positioning members 3 is maintained. This avoids the need to manually move the positioning members 3 that are staggered on different slide rails 21 to the same vertical line when performing vertical or angle measurements.

[0040] The above description is merely illustrative of the invention. Those skilled in the art can make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined by the claims, all of which should fall within the protection scope of this invention.
