Description

Technical Field

[0001] The utility model relates to the technical field of ear canal scanners, in particular to a portable 3D ear canal scanner. Background Art

[0002] In today's medical technology field, accurate medical diagnosis and treatment increasingly rely on high-quality imaging technologies and data acquisition tools. In the field of otology, the three-dimensional shape of the ear canal is particularly important for the customized production of hearing aids and ear molds.

[0003] Most of the existing ear canal scanners are large in size, making it difficult to operate flexibly in the narrow ear canal. In addition, the data transmission and real-time monitoring functions during the scanning process are relatively lacking, which limits the doctor's real-time guidance and remote collaboration capabilities during the scanning process. Summary of the Utility Model

[0004] The technical problem solved by the utility model is to provide a portable 3D ear canal scanner that can realize remote monitoring of ear canal scanning while being easy to carry.

[0005] The basic solution provided by the utility model: A portable 3D ear canal scanner includes a scanning mechanism and a remote monitoring mechanism;

[0006] The scanning mechanism includes a handheld part, a cylinder is arranged at the front end of the handheld part, a motor is arranged on the piston rod of the cylinder, a probe is arranged on the motor shaft of the motor, and a laser emission device and a camera are installed on the probe;

[0007] It also includes a first controller and a first communication module, and the first controller is electrically connected to the cylinder, the motor, the laser emission device, the first communication module and the camera respectively;

[0008] The remote monitoring mechanism includes a second controller, a second communication module and a display module, and the second controller is electrically connected to the second communication module and the display module respectively;

[0009] The scanning mechanism and the remote monitoring mechanism are communicatively connected through the first communication module and the second communication module.

[0010] The principle and advantages of the present utility model are as follows: In this solution, the operator picks up the entire scanner through the handheld part and then inserts the corresponding probe into the ear canal of the person to be scanned. Then, the first controller is used to control the cylinder and the motor, so as to realize the forward and backward telescoping and 360-degree rotation of the probe in the ear canal, and further realize the omnidirectional scanning of the ear canal. During the rotation and telescoping of the probe, the first controller is used to collect data on the ear canal of the person to be scanned by controlling the laser emission device and the camera, and transmit the corresponding collected data to the remote monitoring mechanism through the first communication module. The second controller in the remote monitoring mechanism is used to receive the corresponding collected data through the second communication module and display the data on the display module.

[0011] In this solution, the scanning mechanism and the remote monitoring mechanism are separately arranged and communicatively connected through the corresponding communication module, making the entire scanner easy to carry. At the same time, the remote monitoring mechanism realizes the remote monitoring of ear canal scanning, facilitating remote guidance by other personnel during the scanning process.

[0012] Furthermore, the scanning mechanism further includes a first button and a second button electrically connected to the first controller.

[0013] Beneficial effects: In this solution, after the first button is pressed by the operator, the first controller is used to start the motor and the cylinder, thus realizing the controllability of startup. At the same time, the operator can control the motor and the cylinder to stop running at any time through the second button, thus realizing the termination of scanning at any time.

[0014] Furthermore, both the first communication module and the second communication module are wireless communication modules.

[0015] Beneficial effects: The wireless communication method does not require wiring and is simple and convenient to deploy.

[0016] Furthermore, the wireless communication module includes one or more of a WIFI module, a Bluetooth module, a mobile communication module, a near-field communication module, a ZigBee module, and a Lora module.

[0017] Beneficial effects: Multiple networking methods, with stronger versatility.

[0018] Furthermore, the scanning mechanism further includes a delay module and an alarm module electrically connected to the first controller.

[0019] Beneficial effects: In this solution, the first controller is used to start the delay module for timing after detecting that the first button is pressed. At the same time, the corresponding laser emission device and camera are also started. After the delay module finishes delaying, it sends an end signal to the first controller. The first controller is used to control the alarm module to give an alarm and stop the operation of the laser emission device and camera after receiving the end signal. By setting the delay module, the control of the ear canal scanning time is realized, and after the scanning time arrives, an alarm is given through the alarm module to inform. At this time, the operator can take out the probe from the ear canal of the person being scanned, thereby terminating the scanning operation.

[0020] Further, the alarm module is a warning light.

[0021] Beneficial effects: Through the lamp tube for prompting, it is ensured that the operator can obtain the alarm reminder without causing interference to the operator.

[0022] Further, the scanning mechanism further includes a protection seat for protecting the probe. An installation groove for the front end of the handheld part to extend into is provided on the protection seat. A protection groove for the probe to extend into is provided at the bottom of the installation groove. The opening size of the protection groove is smaller than the diameter of the front end of the handheld part.

[0023] Beneficial effects: The setting of the protection seat can protect the probe at the front end of the handheld part when the handheld part is not in use, and better protect the camera and laser emission device on the probe. The opening size of the protection groove is smaller than the diameter of the front end of the handheld part. When the handheld part tries to insert into the protection groove, due to the diameter limitation, the front end of the handheld part will not be able to enter, and only the probe can pass through smoothly, thereby realizing the protection of the probe.

In this embodiment, the front end of the handheld part 1 is fixedly connected to the cylinder, the piston rod of the cylinder is fixedly welded to the motor, and the motor shaft of the motor is fixedly welded to the probe 2. By setting the cylinder, it can be realized that the probe 2 can be driven to stretch back and forth on the basis of the stretching of the piston rod of the cylinder, so that the probe 2 can stretch back and forth when it extends into the ear canal. The setting of the motor is that during the stretching process of the probe 2, the probe 2 is driven to rotate 360 degrees by the rotation of the motor shaft, so as to realize that the probe 2 can rotate 360 degrees and stretch back and forth in the ear canal.
