Description
Technical Field
[0001] This utility model relates to the field of visual probes, specifically to a visual probe for acoustic impedance. Background Technology
[0002] Acoustic impedance testing, an objective clinical hearing test that assesses the functional status of the middle ear by measuring its acoustic impedance or acoustic admittance, is of great diagnostic value in the localization of middle ear lesions and facial nerve lesions. Traditional acoustic impedance testing requires sealing the external auditory canal with a probe. However, in patients with narrow, tortuous, or cerumen-impacted external auditory canals, this can easily lead to inaccurate probe positioning and poor sealing, affecting the accuracy of the test results.
[0003] To address these issues, probes equipped with cameras have emerged in the industry to allow observation of the external auditory canal during insertion, ensuring accurate placement. However, the camera lens may become contaminated with secretions, necessitating its removal from the probe body for thorough cleaning. This process, however, is cumbersome and time-consuming, impacting cleaning efficiency. Utility Model Content

Detailed Implementation
[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0023] like Figure 1-3As shown, a visualization probe for acoustic impedance includes a probe body 10 and a camera 20. A connecting base 70 is provided on the lower end of the probe body 10, and a communication channel 12 is provided on the probe body 10. A signal transmission line 13 detachably connected to the camera 20 is provided within the communication channel 12. A first positioning device 30 is provided on one side of the connecting base 70, and a second positioning device 40 is provided on the other end. The first positioning device 30 includes a first positioning element 31; the second positioning device 40 includes a second positioning element 41. A first positioning groove 21 for embedding the first positioning element 31 is provided on one side of the camera 20, and a second positioning groove 22 for embedding the second positioning element 41 is provided on the other side of the camera 20. The connecting base 70 is also provided with a first adjusting element 50 for controlling the first positioning element 31 to enter and exit the first positioning groove 21, and a second adjusting element 60 for controlling the second positioning element 41 to enter and exit the second positioning groove 22.
[0024] During the disassembly of camera 20, the first adjusting member 50 controls the first positioning member 31 to move out of the first positioning groove 21, and the second adjusting member 60 controls the second positioning member 41 to move in and out of the second positioning groove 22, thus separating camera 20 from probe body 10. This allows for rapid separation of camera 20 from probe body 10, improving disassembly efficiency and ease. During the installation of camera 20, camera 20 and probe body 10 are properly aligned. The first adjusting member 50 controls the first positioning member 31 to move into the first positioning groove 21, and the second adjusting member 60 controls the second positioning member 41 to move into the second positioning groove 22. This ensures that the first positioning groove 21 engages with the first positioning device 30, and the second positioning groove 22 engages with the second positioning device 40, thereby quickly completing the installation of camera 20 from probe body 10 and improving the efficiency of camera installation. The installation efficiency between the camera 20 and the probe body 10 is improved. Therefore, the present invention provides a visual probe for acoustic impedance, which has a connecting seat 70 on the lower end of the probe body 10, a first positioning device 30 on one side of the connecting seat 70 and a second positioning device 40 on the other end, a first positioning groove 21 that cooperates with the first positioning device 30 on one side of the camera 20, and a second positioning groove 22 that cooperates with the second positioning device 40 on the other side of the camera 20. The connecting seat 70 also has a first adjusting member 50 for controlling the first positioning member 31 to enter and exit the first positioning groove 21 and a second adjusting member 60 for controlling the second positioning member 41 to enter and exit the second positioning groove 22. This makes the disassembly and assembly of the camera 20 and the probe body 10 more convenient and time-saving, and facilitates the thorough cleaning of the camera 20.
[0025] The connecting seat 70 is provided with a first mounting cavity 71, and the first positioning device 30 is installed in the first mounting cavity 71, thereby facilitating the installation of the first positioning device 30.
[0026] The first positioning member 31 is movably installed in the first mounting cavity 71; the first positioning device 30 also includes a first elastic member 32; the first elastic member 32 abuts against the cavity wall of the first positioning member 31 and the first mounting cavity 71, and the first elastic member 32 is used to provide an elastic force to cause the first positioning member 31 to move toward the second positioning member 41, so as to facilitate the installation of the first positioning device 30 and reduce costs.
[0027] The first positioning member 31 is a first pin. The end of the first pin near the second positioning member 41 is set as the first embedding end. The first embedding end is provided with a first spherical surface 33. By using the first pin for the first positioning member 31 and providing the first spherical surface 33 on the first embedding end, it is convenient for the first embedding end of the first pin to move in or out of the first positioning groove 21.
[0028] Preferably, the first elastic element 32 is a first spring, which facilitates installation and reduces costs.
[0029] The first adjusting member 50 includes a first screw 51 and a first abutting block 52. The first screw 51 is threadedly connected to the connecting seat 70, and the first abutting block 52 is movably mounted on the connecting seat 70. The first screw 51 and the first abutting block 52 are rotatably coupled relative to each other. The first abutting block 52 is provided with a first abutting inclined surface 53 for pushing against the first pin. In use, by rotating the first screw 51 in the forward direction, the first abutting block 52 moves upward under the driving force of the first screw 51, and the first abutting inclined surface 53 of the first abutting block 52 pushes against the first pin, so that the first pin moves towards the inside of the first mounting cavity 71 and moves out of the first positioning groove 21, thereby realizing the separation of the first pin from the camera 20. After the camera 20 is thoroughly cleaned and installed on the connector 70, the first screw 51 is rotated in the opposite direction, causing the first abutment block 52 to move downward under the action of the first screw 51. The first spring returns to its elastic state, and the first pin moves outward from the first mounting cavity 71 under the elastic force of the first spring and moves into the first positioning groove 21. Thus, the camera 20 can be locked by the first pin, which facilitates operation, further improves operating efficiency, and saves time.
[0030] The first pin is provided with a first guide block, and the first guide block is provided with a first mating inclined surface. The inclination of the first mating inclined surface matches the inclination of the first abutting inclined surface 53, so that during the forward rotation of the first screw 51, the first pin can move toward the inside of the first mounting cavity 71 under the action of the first abutting block 52.
[0031] The connecting seat 70 is provided with a second mounting cavity 72, and the second positioning device 40 is installed in the second mounting cavity 72, thereby facilitating the installation of the second positioning device 40.
[0032] The second positioning member 41 is movably installed in the second mounting cavity 72; the second positioning device 40 also includes a second elastic member 42; the second elastic member 42 abuts against the cavity wall of the second positioning member 41 and the second mounting cavity 72, and the second elastic member 42 is used to provide an elastic force to cause the second positioning member 41 to move toward the first positioning member 31, so as to facilitate the installation of the second positioning device 40 and reduce costs.
[0033] The second positioning member 41 is a second pin. The end of the second pin near the first positioning member 31 is set as the second embedding end. The second embedding end is provided with a second spherical surface 43. By using a second pin for the second positioning member 41 and providing a second spherical surface 43 on the second embedding end, it is convenient for the second embedding end of the second pin to move in or out of the second positioning groove 22.
[0034] Preferably, the second elastic element 42 is a second spring, which facilitates installation and reduces costs.
[0035] The second adjusting member 60 includes a second screw 61 and a second abutting block 62. The second screw 61 is threadedly connected to the connecting seat 70, and the second abutting block 62 is movably mounted on the connecting seat 70. The second screw 61 and the second abutting block 62 are rotatably coupled to each other. The second abutting block 62 is provided with a second abutting inclined surface 63 for pushing the second pin. In use, by rotating the second screw 61 in the forward direction, the second abutting block 62 moves upward under the driving force of the second screw 61, and pushes the second pin with the second abutting inclined surface 63 of the second abutting block 62, so that the second pin moves toward the inside of the second mounting cavity 72 and moves out of the second positioning groove 22, thereby realizing the separation of the second pin from the camera 20. After the camera 20 is thoroughly cleaned and installed on the connector 70, the second screw 61 is rotated in the opposite direction, causing the second abutment block 62 to move downward under the action of the second screw 61. The second spring returns to its elastic state, and the second pin moves outward from the second mounting cavity 72 under the elastic force of the second spring and moves into the second positioning groove 22. Thus, the camera 20 can be locked by the second pin, which facilitates operation, further improves operating efficiency, and saves time.
[0036] The second pin is provided with a second guide block, and the second guide block is provided with a second mating inclined surface. The inclination of the second mating inclined surface matches the inclination of the second abutting inclined surface 63, so that during the forward rotation of the second screw 61, the second pin can move toward the inside of the second mounting cavity 72 under the action of the second abutting block 62.
