Description

Technical Field

[0001] This utility model belongs to the field of hair transplantation technology, specifically, it relates to a laser marker that facilitates the calculation of head area. Background Technology

[0002] Hair transplantation is a surgical technique that transplants healthy hair follicles to areas of hair loss or thinning to improve hair distribution and increase density. The procedure typically uses follicular unit transplantation (FUT) or follicular unit extraction (FUE) to extract healthy hair follicles and transplant them to the desired area. The transplanted hair retains its original growth characteristics and continues to grow in the new area. In the field of hair transplantation, before diagnosis, the area requiring transplantation needs to be calculated, and the area must be marked on the scalp with a professional pen. Previously, a ruler was used to draw lines and measure the area, which resulted in significant errors and made drawing straight lines difficult.

[0003] In view of this, this utility model is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a laser marker that is convenient for measuring head area.

A battery is housed within the main housing, and the control circuit board is located on the side of the battery. A gyroscope mounting bracket is fixedly mounted on the upper part of the main housing, and a three-axis gyroscope is positioned below the bracket. A grid laser source is positioned above the bracket, with its end connected to a gun head housing. A distance sensor is positioned on the gun head housing below the grid laser source, and a crosshair laser source is positioned below the distance sensor. The gun head housing has detection and mounting holes that mate with the grid laser source, the distance sensor, and the crosshair laser source. An outer protective frame is located on the side of the main housing away from the gun head housing, and a screen panel with an LCD screen inside the frame indicates the position of the laser source and displays the angle of the three-axis gyroscope.

The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0017] like Figures 1 to 4 As shown, a laser marker for easy measurement of head area includes a main housing 1 and a control circuit board 8. A battery 7 is housed inside the main housing 1, and the control circuit board 8 is located on the side of the battery 7. A gyroscope mounting bracket 12 is fixedly mounted on the upper part of the main housing 1. A three-axis gyroscope 13 is mounted below the gyroscope mounting bracket 12. A grid laser source 11 is mounted above the gyroscope mounting bracket 12, and the end of the grid laser source 11 is connected to a gun head housing 9. The gun head housing 9 is located on the grid... A ranging sensor 14 is located below the laser source 11, and a cross laser source 15 is located below the ranging sensor 14. The gun head housing 9 is provided with detection and mating mounting holes 20 that cooperate with the grid laser source 11, the ranging sensor 14, and the cross laser source 15. An outer protective frame 4 is provided on the side of the main housing 1 of the marker away from the gun head housing 9. A screen panel 2 is provided inside the outer protective frame 4. An LCD screen 3 is provided on the screen panel 2 to indicate the position of the laser source and display the angle of the three-axis gyroscope 13.

[0018] Among them, the LCD screen 3 is a color screen, and the lower part of the outer protective frame 4 is equipped with a status light 17 to indicate the working status of the marker.

[0019] The lower end of the main housing 1 of the road marker is provided with a charging interface 5, which is a TYPE-C connector. The charging interface 5 is electrically connected to the battery 7. A handle shell 6 is provided on the outside of the battery 7. The battery 7 is used to supply power to the electrical components inside the main housing 1 of the road marker.

[0020] The handle shell 6 is provided with anti-slip texture. The main shell 1 of the marker is provided with a mating block 16 at the position that mates with the handle shell 6. The handle shell 6 is provided with a mating groove 21. The handle shell 6 is installed and fixed by the mating block 16 and the mating groove 21, which makes it easy to install and disassemble.

[0021] A sight 10 is located in the middle of the upper part of the main housing 1 of the line marker, near the gun head housing 9. A light source switching key 18 and a switch button 19 are provided on the control circuit board 8. A hollowed-out groove is provided on the main housing 1 of the line marker corresponding to the light source switching key 18 and the switch button 19 to facilitate the operation of the buttons.

[0022] The grid laser source 11 displays a 16*16 square grid, while the cross laser source 15 displays a "+" pattern for easy indication and positioning.

[0023] The working principle of this utility model is as follows: A high-sensitivity distance sensor is set in front of the line marker to measure the distance from the laser head to the patient's head. A high-sensitivity 3-axis gyroscope is set inside the line marker to accurately measure the horizontal angle. A color LCD screen 3 is set at the rear of the product to display the current angle value and the current distance. The angle value is the horizontal angle detected by a single axis. When the angle value is 0, it is standard. The distance value is a fixed value of 40cm. The displayed grid area is 1 square centimeter, which makes it easier to measure the area. When the distance is >40cm, there will be an arrow on the screen to indicate that the line should be moved forward. Conversely, it should be moved backward. When the distance value is exactly 40cm, there will be a buzzer inside the machine to indicate that the current angle and distance are optimal. Area measurement and line marking can be performed. When marking, the line is adjusted to the grid laser source state and the line is marked in the grid screen, which can improve the accuracy of the line marking. The grid laser source 11 displays a 16*16 square grid, and the cross laser source 15 displays a "+" pattern. Specific operation process: Press and hold the power button to turn on the device. The grid light source will be displayed automatically by default. Adjust the angle to 0 and the distance to 40cm. The buzzer will sound once. The area will be calculated and the lines will be drawn. The light source switch button 18 can cycle between the "+" light source and the grid light source. This utility model has a reasonable structural design and is easy to install and use. The marking device is equipped with a grid laser source 11, a cross laser source 15, a three-axis gyroscope 13, and a distance sensor 14. The three-axis gyroscope 13 is used to accurately calculate the horizontal angle, and the distance sensor 14 is used to calculate the distance from the laser head to the patient's head. The angle value is the horizontal angle detected on a single axis. When the angle value is 0, it is standard. The distance value is a fixed value of 40cm. The displayed grid area is 1 square centimeter, which is convenient for calculating the area and marking.
