Problems solved by technology

However, due to the variety of acoustic signals and the diversity of the relationship between laryngeal muscle movement, vocalization, and breathing, this method is relatively complicated. Therefore, there is still a lot of research to be done before clinical application

Embodiment 1

[0036] Embodiment 1 of the present invention provides a system for micromechanical treatment of unilateral vocal cord paralysis, such as figure 1 As shown, the system includes:

[0037] The vocal cord movement acquisition device on the healthy side is used to collect the movement of the vocal cord on the healthy side when the user makes a sound, and send the collected movement information to the processor 3;

[0038] The first micromachine 2 is used for implanting in the larynx of the affected side, receives the movement signal sent by the processor 3, and generates micromechanical movement to drive the vocal cord of the affected side to produce synchronous movement;

[0039] The processor 3 is used to receive the motion information sent by the vocal cord motion collector on the healthy side, process the motion information to form a motion signal, and send it to the first micromachine 2 .

[0040] The first micromachine 2 includes a first fixing part 201 fixed at the thyroid...

Embodiment 2

[0045]Embodiment 2 of the present invention provides a system for micromechanical treatment of unilateral vocal cord paralysis. The difference between this system and Embodiment 1 is as follows: figure 2 As shown, the first fixing part 201 and the transmission part 202 of the first micromachine 2 are both plate-shaped structures, and the lower ends are provided with grooves 204 in the opening direction. The left and right sides of the groove 204 correspond to the first fixing parts. The side of the transmission part 201 and the transmission part 202 are hinged by a central shaft 205 , a fixed disk 206 is fixedly arranged on the central shaft 205 , and the driving part 203 is arranged on the fixed disk 206 .

[0046] The fixed part and the transmission part are provided with grooves, and the two ends are hinged to form a space for placing the driving parts. When implanted in the body, the invasion and damage to the patient's body are minimized, which is beneficial to the patien...

Embodiment 3

[0048] Embodiment 3 of the present invention provides a system for micromechanical treatment of unilateral vocal cord paralysis. The difference between this system and Embodiment 1 is that, as Figure 3-5 As shown, the driving part includes a micromotor 301 arranged on a fixed disk 206 below the central axis 205, the output direction of the output shaft 302 of the micromotor 301 is perpendicular to the fixed disk 206, and the free end of the output shaft 302 is provided with a first Gear 303; the outer surface of the micro motor 301 is provided with an extension plate 304 vertically extending to the transmission part 202, and the extension plate 304 is provided with a slide rail 305 perpendicular to the transmission part 202; the first gear 303 is provided on the surface away from the output shaft 302 There is a circular chute 309, a first driving rod 306 is slidably connected in the circular chute 309, and a second driving rod 307 is hinged to the end of the first driving rod ...

Abstract

The invention provides a system for treating unilateral vocal cord paralysis by micro-machine treatment. The system includes: a vocal cord motion collecting device on the healthy side, which is used to collect the motion of the vocal cords on the healthy side when a user makes a sound, and collect the motion information collected. sent to the processor; the first micromachine is used for implanting in the larynx of the affected side, receives the motion signal sent by the processor, and generates micromechanical motion to drive the vocal cords of the affected side to generate synchronous motion; the processor is used to receive the motion of the vocal cords of the healthy side The motion information sent by the collector is processed to form a motion signal, which is sent to the first micromachine. Using micro-machines, its movement can drive the movement of the affected side vocal cords, thereby replacing the muscle function that closes the vocal cords and restoring the movement of the affected side vocal cords. The use of micromachines avoids electrical stimulation due to different muscle functions or states. The effect is uncontrollable and avoids the loss of electrical stimulation function caused by vocal cord muscle atrophy.

Description

technical field [0001] The invention belongs to the field of treating unilateral vocal cord paralysis, in particular to a micromechanical system for treating unilateral vocal cord paralysis. Background technique [0002] Many reasons in life can cause unilateral vocal cord movement disorders, including idiopathic unilateral vocal cord paralysis, unilateral vocal cord paralysis caused by tumors, trauma, etc. After vocal cord paralysis, the vocal cords on the affected side cannot move normally, so that the bilateral vocal cords cannot be close enough when the patient makes a sound, resulting in hoarseness, and some patients may also have symptoms such as choking and coughing. [0003] The treatment methods used in clinical practice are generally nerve transplantation and neuromuscular transplantation to restore the power of the vocal cords. These treatments have poor precision and unsatisfactory results, and some may at best restore muscle tone, but not voluntary movement. I...
