Description

Technical Field

[0001] This utility model relates to the field of medical aesthetics technology, specifically a multifunctional nasal measuring instrument. Background Technology

[0002] During rhinoplasty, to ensure a more aesthetically pleasing result, the height of the nasal root and bridge must meet specific proportions. Therefore, the height of these areas needs to be measured before the procedure, and adjustments made accordingly during the surgery.

[0003] The existing patent, CN217793048U, entitled "A Nasal Measuring Device," relates to the field of orthopedic auxiliary devices and specifically discloses a nasal measuring device. It includes a measuring body with an arc-shaped cross-section. The measuring body has a small end and a large end, with the width and height of the small end being smaller than those of the large end, respectively. The measuring body has a transparent portion and a height measuring scale opposite to the transparent portion, extending along the cross-sectional direction of the measuring body. This nasal measuring device reduces measurement errors and makes measurement more convenient and faster.

[0004] The aforementioned device has a height measurement scale opposite to the transparent part, which extends along the cross-sectional direction of the measuring body. However, the measurement relies on the doctor's visual judgment and has low accuracy, making it impossible to obtain accurate nasal data and failing to meet people's usage needs. In response to the above situation, technological innovation is carried out based on the existing nasal measuring instrument. Utility Model Content

[0005] The purpose of this invention is to provide a multifunctional nasal measuring instrument to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional nose measuring instrument, comprising an outer frame and a forehead protector. A support rod is installed on the lower left side of the outer frame, the forehead protector is installed on the upper rear end of the inner side of the outer frame, and a lower pad is installed on the lower inner side of the outer frame. A guide rod is installed on the right side of the outer frame, and a screw is provided on one side of the guide rod. An adjustment component is installed above the screw, and the adjustment component is welded to the screw. The person being measured extends their face into the outer frame, places their chin on the lower pad, and presses their forehead against the forehead protector, which facilitates the determination of the face position.

[0007] Furthermore, the adjustment assembly includes an adjustment knob and a bevel gear set, and the bevel gear set is installed on one side of the adjustment knob. Rotating the adjustment knob drives the bevel gear set to rotate, and the bevel gear set drives the screw to rotate.

[0008] Furthermore, a guide rail is installed on the periphery of the screw, and the guide rail is threadedly connected to the screw. The screw guide rail moves up and down on the guide rod under the drive of the screw.

[0009] Furthermore, a sliding rod assembly is installed around the guide rail, and the sliding rod assembly is slidably connected to the guide rail, allowing the sliding rod assembly to move back and forth on the guide rail.

[0010] Furthermore, a slider is slidably connected to the periphery of the slide bar assembly, and a 3D scanner is mounted on one side of the slider. The slider drives the 3D scanner to move left and right on the slide bar assembly, thereby aligning the 3D scanner with the nose of the person being measured.

[0011] Furthermore, a column is installed below the support rod, and the column and the support rod are embedded together. The support rod can slide and rise and fall inside the column, and the length of the support rod in the column can be adjusted according to the height of the person being measured.

[0012] Furthermore, a fastening knob is installed on one side of the column, and the fastening knob is threaded to the column. By screwing the fastening knob into the column, the column is pressed against the support rod, thereby fixing the height of the device.

[0013] Furthermore, a base is installed below the column, and a pulley is installed below the base, so that the device can be pushed to the front of the person being measured by the pulley under the base.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the length of the support rod in the column is adjusted according to the height of the person being measured, and then the height of the device is fixed by screwing the fastening knob into the column to hold the support rod. This makes it convenient to adapt to people of different body types. The person being measured puts their face into the outer frame, places their chin on the lower pad, and presses their forehead against the forehead protector to easily determine the face position. According to the face shape of the person being measured, the adjustment knob is rotated to drive the bevel gear group to rotate. The bevel gear group drives the screw to rotate. The screw guide rail moves up and down on the guide rod under the drive of the screw. The slide bar group moves back and forth on the guide rail. The slider drives the 3D scanner to move left and right on the slide bar group, so that the 3D scanner is aligned with the nose position of the person being measured and performs a 3D scan of the nose to obtain accurate nose model data.

[0015] 1. In this utility model, the subject inserts their face into the outer frame, places their chin on the lower pad, and presses their forehead against the forehead protector to facilitate determining the face position. According to the subject's face shape, rotating the adjustment knob drives the bevel gear set to rotate, which in turn drives the screw to rotate. The screw guide rail moves up and down on the guide rod under the drive of the screw, and the slide bar set moves back and forth on the guide rail. The slider drives the 3D scanner to move left and right on the slide bar set, thereby aligning the 3D scanner with the subject's nose position and performing a 3D scan of the nose to obtain accurate nasal model data. This allows for accurate nasal data, which is convenient for determining the subsequent treatment plan.

[0016] 2. This utility model uses pulleys under the base to push the device in front of the person being measured. The length of the support rod in the column is adjusted according to the height of the person being measured. Then, the height of the device is fixed by screwing the fastening knob into the column to hold the support rod against it. This makes it convenient for people of different body types to use.
