Description

Technical Field

[0001] This utility model relates to the field of orbital measurement instruments, specifically to a periorbital measurement and positioning tool. Background Technology

[0002] Periorbital measurement has important applications in both medical and cosmetic fields. It mainly includes the measurement of several key data, such as the medial and lateral orbital distances, the interorbital distance, and the degree of eyeball protrusion. Currently, the most common tool for measuring eyeball protrusion is a transparent ruler. During the measurement, the doctor places the 0 mark of the ruler against the temporal side of the patient's orbital rim, and has the patient look straight ahead. The doctor then observes the corneal apex on the ruler from the side to determine the degree of protrusion. Although this method is convenient for testing, the data obtained is relatively coarse and not accurate enough. Utility Model Content

[0003] This invention provides a periorbital measurement and positioning tool that can overcome some or all the defects of the prior art.

[0004] According to the present invention, a periorbital measurement and positioning tool includes: a tool body, the tool body including a horizontal plate arranged along the width direction of the face, and measuring elements at both ends of the horizontal plate; the horizontal plate and the two measuring elements together constitute a receiving area for accommodating the eye; the measuring element includes a mounting block, and a scale arranged along the length direction of the mounting block is provided at the end of the mounting block away from the receiving area; a sliding groove is provided at the mounting block along the length direction of the mounting block; a movable plate is provided at the sliding groove, one end of which extends toward the eye and the other end of which extends into the area below the scale; the movable plate slides in conjunction with the sliding groove.

[0005] With this invention, when a doctor tests a patient's eye protrusion, the main body of the tool is first moved to the patient's eye area. Then, the horizontal plate is pushed above the patient's eyes, and the mounting blocks are moved to both sides of the patient's head so that the 0 mark of the scale on the mounting block is aligned with the patient's temporal orbital rim, while keeping the horizontal plate horizontal. The patient is then asked to look straight ahead, at which point the patient's left and right eyes are within the receiving area. The doctor then pushes the moving plate along the groove towards the eye until the moving plate contacts the apex of the patient's cornea. The doctor then observes and records the reading on the scale at one end of the moving plate, thus obtaining the patient's eye protrusion. Compared with the prior art, this device indicates the logarithm on the scale through the moving plate, making it easier for doctors to more accurately determine the patient's eye protrusion.

[0006] Preferably, the mounting block has a through hole for the horizontal plate to pass through.

[0007] With this invention, doctors can push the mounting block to slide along the axial direction of the horizontal plate, thereby expanding the accommodating area and enabling the device to adapt to different patient face sizes.

[0008] Preferably, the inner wall of the through hole is provided with a first rough surface, and the horizontal plate is provided with a second rough surface that matches the first rough surface.

[0009] With this invention, a first rough surface is provided on the inner sidewall of the through hole, which contacts a second rough surface on the surface of the horizontal plate. This prevents the mounting block from sliding due to the friction between the first and second rough surfaces when the doctor does not push the mounting block, thereby preventing the mounting block from sliding on the horizontal plate and affecting the test data when the doctor is examining the patient.

[0010] Preferably, the chute has a T-shaped cross-section, and the movable plate includes a sliding plate extending into the chute and a baffle connected to the sliding plate; the sliding plate is T-shaped.

[0011] With this invention, the T-shaped sliding plate moves along the T-shaped groove, thereby preventing the sliding plate from detaching from the groove and enhancing the stability of the sliding plate during movement.

[0012] Preferably, both ends of the slide groove are provided with openings communicating with the slide groove.

[0013] With this invention, after a doctor has finished examining a patient, he can push the movable plate to slide it out of the groove from the opening. When the next patient needs to use it, a new movable plate can be installed, which makes it convenient for the doctor to change the movable plate.

[0014] Preferably, the horizontal plate, mounting block, movable plate, and scale are all made of plastic.

[0015] Because of the lightweight nature of the plastic, the tool body is easy for doctors to lift. Furthermore, the movable plate is made of transparent plastic, allowing the patient to see ahead through the movable plate when it is pushed close to the patient's eyeball, thus preventing the patient from closing their eyes when the movable plate is close to their eyeball.

[0020] To further understand the content of this utility model, a detailed description of the utility model is provided in conjunction with the embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the utility model.

[0021] Example 1

[0022] like Figure 1-4 As shown, this embodiment provides a periorbital measurement and positioning tool, including a tool body 100. The tool body 100 includes a horizontal plate 110 arranged along the width direction of the face, and measuring elements 120 are provided at both ends of the horizontal plate 110. The horizontal plate 110 and the two measuring elements 120 together form a receiving area 160 for accommodating the eye. The measuring element 120 includes a mounting block 360. A scale 140 is provided at one end of the mounting block 360 away from the receiving area 160, along the length direction of the mounting block 360. A sliding groove 340 is provided at the mounting block 360, along the length direction of the mounting block 360. A movable plate 130 is provided at the sliding groove 340, with one end extending towards the eye and the other end extending into the area below the scale 140. The movable plate 130 and the sliding groove 340 are slidably engaged.

[0023] In this embodiment, when testing a patient's eye protrusion, the doctor first moves the main body 100 of the tool to the patient's eye area, then pushes the horizontal plate 110 above the patient's eye, and moves the mounting block 360 to both sides of the patient's head, so that the 0 mark of the scale 140 on the mounting block 360 is aligned with the patient's temporal orbital rim, and keeps the horizontal plate 110 horizontal. Then, the patient is asked to look straight ahead, at which point the patient's left and right eyes are within the receiving area 160. The doctor then pushes the moving plate 130 along the slide 340 toward the eye until the moving plate 130 contacts the apex of the patient's cornea. The doctor then observes and records the mark on the scale 140 at one end of the moving plate 130, thus obtaining the patient's eye protrusion. Compared with the prior art, this device indicates the logarithm on the scale 140 through the moving plate 130, thereby making it easier for the doctor to more accurately know the patient's eye protrusion.

[0024] In this embodiment, the mounting block 360 is provided with a through hole 330 for the horizontal plate 110 to pass through.

[0025] In this embodiment, the doctor can push the mounting block 360 to slide along the axis of the horizontal plate 110, thereby expanding the accommodating area 160 and enabling the device to adapt to different patient face sizes.

[0026] In this embodiment, a first rough surface 310 is provided on the inner wall of the through hole 330, and a second rough surface 150 that cooperates with the first rough surface 310 is provided on the horizontal plate 110.

[0027] In this embodiment, the inner wall of the through hole 330 is provided with a first rough surface 310 that contacts the second rough surface 150 on the surface of the horizontal plate 110. This prevents the mounting block 360 from sliding due to the friction between the first rough surface 310 and the second rough surface 150 when the doctor does not push the mounting block 360. This prevents the mounting block 360 from sliding on the horizontal plate 110 and affecting the test data when the doctor is examining the patient.

[0028] In this embodiment, the slide 340 has a T-shaped cross-section, and the movable plate 130 includes a sliding plate 410 extending into the slide 340 and a baffle 420 connected to the sliding plate 410; the sliding plate 410 has a T-shaped shape.

[0029] In this embodiment, the T-shaped sliding plate 410 moves along the T-shaped groove 340, thereby preventing the sliding plate 410 from disengaging from the groove 340 and also enhancing the stability of the sliding plate 410 during movement.

[0030] In this embodiment, both ends of the slide groove 340 are provided with openings 350 that communicate with the slide groove 340.

[0031] In this embodiment, after a doctor has finished examining a patient, he can push the movable plate 130 so that the movable plate 130 slides out of the groove 340 from the opening 350. When the next patient needs to use it, a new movable plate 130 can be installed, which makes it convenient for the doctor to replace the movable plate 130.

[0032] In this embodiment, the horizontal plate 110, the mounting block 360, the movable plate 130, and the scale 140 are all made of plastic.

[0033] In this embodiment, because the plastic is lightweight, it is easy for the doctor to lift the main body of the tool 100. Furthermore, the movable plate 130 is made of transparent plastic, so that when the doctor pushes the movable plate 130 and it is close to the patient's eyeball, the patient can see forward through the movable plate 130, thus avoiding the patient closing their eyes when the movable plate 130 is close to the patient's eyeball.

[0034] It is readily understood that those skilled in the art can combine, split, or reorganize the embodiments provided in this application to obtain other embodiments, all of which do not exceed the protection scope of this application.

[0035] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the embodiments shown are only part of the embodiments of the present invention. The actual structure is not limited to this. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
