Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a visible recurrent laryngeal nerve monitoring catheter. Background Art

[0002] The visible recurrent laryngeal nerve monitoring catheter is an important device for monitoring and protecting the recurrent laryngeal nerve during thyroid and parathyroid surgeries. Through this monitoring catheter, doctors can monitor the functional status of the recurrent laryngeal nerve in real time during the surgery, thereby reducing the risk of nerve injury. When monitoring and protecting the recurrent laryngeal nerve, the catheter needs to be placed in the glottis area and fixed to ensure its stability during the surgery.

[0003] When fixing the tracheal catheter, usually adhesive tape is used to fix the tracheal catheter along its direction on the patient's face, ensuring that the adhesive tape is in full contact with the skin to avoid the movement or rotation of the catheter. During the surgery, if the patient's body position changes, the position of the catheter needs to be readjusted according to the change of the patient's body position. When fixing the catheter with adhesive tape, the movement or rotation of the catheter can be avoided, but when the position of the catheter needs to be adjusted, the catheter needs to be detached from the adhesive tape and then the position of the catheter is adjusted, which is inconvenient during the adjustment. Moreover, when the adhesive tape is used again after being separated from the skin, it may have a certain impact on the fixing effect of the catheter. Therefore, this application provides a visible recurrent laryngeal nerve monitoring catheter to meet the needs. Summary of the Utility Model

[0030] As Figures 1 to 4 shown, an embodiment of the present utility model provides a visible recurrent laryngeal nerve monitoring catheter, including a catheter 1, a main body arc plate 2, and a fixing member 3. A limiting card slot 4 is arranged inside the main body arc plate 2. The fixing member 3 includes a first clamping plate 301 which is arranged on the outer wall of the main body arc plate 2. A first weakening groove 302 is arranged on the inner wall of the first clamping plate 301. The catheter 1 is fixedly sleeved between two first clamping plates 301. A groove 303 is arranged inside the first clamping plate 301. An elastic sheet 305 is arranged inside the groove 303. A second clamping plate 304 is arranged at one end of the elastic sheet 305. A limiting pressing plate 307 is arranged at one end of the second clamping plate 304. The limiting pressing plate 307 is slidably sleeved inside the limiting card slot 4, and the outer wall of the limiting pressing plate 307 is in contact with the outer wall of the medical tape 16.

[0031] A second weakened groove 306 is provided on the inner wall of the elastic sheet 305, and a paddle 308 is provided on the outer wall of the first clamping plate 301. The number of the first clamping plates 301 is two groups, and they are in a mirror structure. The first clamping plate 301 is an arc-shaped plastic structure. The elastic sheet 305, the second clamping plate 304 and the limiting pressure plate 307 are an integrated structure. The second clamping plate 304 is an arc-shaped plastic structure. The second clamping plate 304 is linearly arranged and distributed inside the first clamping plate 301.

[0032] The first clamping plate 301 and the paddle 308 are both arc-shaped plastic structures, and are an integrated structure with a certain elasticity. The groove 303 is arranged inside the first clamping plate 301 and is linearly arranged inside the first clamping plate 301. The elastic sheet 305 and the limiting pressure plate 307 are arranged at both ends of the second clamping plate 304. The arc surfaces of the first clamping plate 301 and the second clamping plate 304 are opposite. The second clamping plate 304 is arranged inside the groove 303 and is located on the inner wall of the first clamping plate 301. Moreover, the distance between the two groups of second clamping plates 304 is smaller than the distance between the two groups of first clamping plates 301.

[0033] By toggling the paddle 308, the first clamping plate 301 is deformed at the first weakened groove 302, and then the catheter 1 is placed between the two groups of first clamping plates 301. The elasticity of the first clamping plates 301 is then used to clamp and fix the catheter 1. At the same time, the arc surface of the outer wall of the second clamping plate 304 is clamped with the outer wall of the catheter 1, so that the second clamping plate 304 is deformed at the second weakened groove 306. The elasticity of the second clamping plate 304 is then used to clamp and fix the catheter 1. This arrangement can not only clamp and fix the catheter 1, but also avoid the problem of the position of the catheter 1 changing due to the change of the patient's body position. The position of the catheter 1 can be adjusted by separating the two groups of first clamping plates 301, and the medical tape 16 can be squeezed to make the medical tape 16 fit tightly against the patient's skin, thereby avoiding the problem of the medical tape 16 falling off during use.

[0034] like Figure 2 and Figure 3As shown, a placement groove 5 is provided inside the main body arc plate 2. A medical tape 16 is placed inside the placement groove 5. A limiting rod 6 is provided inside the placement groove 5. The medical tape 16 is wound around the outer wall of the limiting rod 6. By providing the main body arc plate 2 and the limiting rod 6, the main body arc plate 2 is an arc-shaped plastic structure, and the outer wall of the main body arc plate 2 is a curved surface. The medical tape 16 is placed on the outer wall of the main body arc plate 2, and the outer wall of the medical tape 16 is attached to the outer wall of the main body arc plate 2, increasing the force-bearing surface of the medical tape 16 in contact with the skin. At the same time, both ends of the medical tape 16 are placed inside the placement groove 5 and wound around the outer wall of the limiting rod 6, so that the medical tape 16 is wound around the surface of the limiting rod 6 and connected to each other, forming a placement circular groove, and the limiting rod 6 is fixed inside the placement circular groove, thereby fixing the medical tape 16 on the outer wall of the limiting rod 6, and further fixing the fixing component 3 on the patient's skin surface with the medical tape 16.

[0035] As Figure 1 shown, a connecting pipe 11 is provided inside the catheter 1. One end of the connecting pipe 11 is provided with an airbag inflation port 12. A pressure indicating valve 13 is installed inside the airbag inflation port 12. One end of the catheter 1 is provided with an airbag 7. The other end of the catheter 1 is provided with a connecting threaded head 10. Monitoring electrodes 8 and a camera 9 are provided on the outer wall of the catheter 1 adjacent to the airbag 7. A connecting wire 14 is provided inside the catheter 1. One end of the connecting wire 14 is electrically connected to the camera 9, and the other end is provided with a plug for connecting to an external screen. Another connecting wire for connecting the monitoring electrode 8 and the corresponding device is also provided inside the catheter 1. The end of this connecting wire is provided with a connector 15 for connecting to the corresponding device, and the electromyogram of the vocal cord activity collected by the monitoring electrode 8 can be transmitted to the corresponding device. By providing the pressure indicating valve 13, the pressure indicating valve 13 is installed inside the airbag inflation port 12 and connected to the airbag 7 through the connecting pipe 11. By the pointer in different color areas, it can reflect in real time whether the pressure inside the airbag 7 is excessive, thereby minimizing the occurrence probability of the above-mentioned complications and improving the safety of the patient.

[0036] The working principle of the technical solution provided by the present utility model is as follows: First, the front end of the catheter 1 is placed inside the patient's trachea, and then the airbag 7 is inflated through the airbag inflation port 12. At the same time, during the inflation process, the pressure indicating valve 13 is used to react to the pressure inside the airbag 7 in real time, avoiding excessive pressure inside the airbag 7, thereby minimizing the occurrence probability of the above-mentioned complications and improving the safety of the patient. At the same time, the camera 9 is placed behind the monitoring electrode 8. On the one hand, the monitoring electrode 8 continues to collect the electromyogram signal of the vocal cord activity. On the other hand, the image of the vocal cord activity can be collected in real time through the camera 9 and transmitted to the external screen, thereby directly reflecting the presence or absence of the vocal cord activity and whether the activity is good.

[0037] Then, after the patient's body position changes, it is necessary to adjust the position of the catheter 1 according to the needs, and then the first clamping plate 301 is deformed at the first weakened groove 302 by toggling the paddle 308, and then the catheter 1 is placed between the two groups of first clamping plates 301, and then the elasticity of the first clamping plate 301 is used to clamp and fix the catheter 1, and at the same time, the outer wall arc surface of the second clamping plate 304 is clamped with the outer wall of the catheter 1, so that the second clamping plate 304 is deformed at the second weakened groove 306, and then the elasticity of the second clamping plate 304 is used to clamp and fix the catheter 1. This arrangement can not only clamp and fix the catheter 1, but also avoid the problem of the position of the catheter 1 changing due to the change of the patient's body position, and the position of the catheter 1 can be adjusted by separating the two groups of first clamping plates 301, and the medical tape 16 can be squeezed to make the medical tape 16 fit closely to the patient's skin, avoiding the problem of the medical tape 16 falling off during use.

[0038] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the preferred embodiment of the present invention, and the present invention can be fully understood by those skilled in the art without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
