Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of nerve probes, and more specifically, the utility model relates to a nerve probe convenient to adjust. Background Technique
[0002] The nerve stimulation probe is used in cooperation with intraoperative electroencephalogram, electromyogram, and evoked potential measurement systems for intraoperative positioning, identifying, and measuring cranial motor nerves, peripheral nerves, and spinal nerve roots. The basic principle of its clinical application is that the nerve stimulation probe contacts the corresponding tissues and nerves through the natural body cavity or surgical incision of the human body, and cooperates with the intraoperative monitoring equipment to generate an automatic periodic stimulation to generate a stimulation current. The stimulated tissues and nerves will guide the corresponding muscles to contract and generate bioelectric signals. At this time, the bioelectricity will be collected by the collection electrode and finally conducted to the nerve monitoring equipment, and the equipment will analyze, compare, and judge, so as to form a complete closed loop and obtain the electromyogram signal to realize continuous nerve detection.
[0003] The prior art has at least the following technical problems: common nerve probes have various length specifications, and there are various distances between bipolar and tripolar probes. Such nerve probes are often integrated. However, during the operation, due to the different physical conditions of the patients, the positions of the surgical wounds, and the operating techniques of the doctors, currently, medical staff often directly bend the probe to adjust the distance between the two probes during the operation. However, the specific distance between the two probes cannot be judged and depends entirely on the experience of the medical staff, which will cause errors in the measurement results. Moreover, when the length of the probe is adjusted sometimes, the specific adjusted length cannot be determined. Therefore, the integrated nerve probe cannot meet the usage requirements of complex application scenarios, resulting in the need to prepare multiple sets of integrated nerve probes with different lengths and distances for the operation. Selecting a suitable nerve probe often requires unplugging and debugging the nerve probe and the equipment back and forth, which will waste a lot of time and surgical costs; if the prepared quantity is insufficient and a nerve probe that meets the specifications cannot be found, it will lead to the interruption of continuous periodic stimulation and the decline of the monitoring effect. Therefore, it needs to be improved and optimized. Content of the Utility Model

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0021] As Figures 1 to 7As shown in the figure, the utility model provides a nerve probe that is convenient to adjust, including a fixed block 5. An angle scale 6 is provided on the top of the fixed block 5. A rotating table 7 is rotatably installed on the top of the fixed block 5. Two limiting sliding grooves 8 are opened on the top of the rotating table 7. A rotating rod 16 is rotatably installed at the bottom of the fixed block 5. The rotating rod 16 penetrates through the fixed block 5 and is fixedly connected to the bottom of the rotating table 7. An adjusting block 15 is fixedly sleeved on the outer wall of the rotating rod 16. Slide rods 9 are respectively slidably installed on the inner walls of the two limiting sliding grooves 8. Protective sleeves 18 are respectively fixedly installed on the tops of the two slide rods 9. Probes 2 are respectively movably installed in the inner walls of the two protective sleeves 18.
[0022] By rotating the adjusting block 15, the adjusting block 15 drives the rotating rod 16 to rotate. The rotating rod 16 drives the rotating table 7 to rotate, thereby driving the two slide rods 9 to slide in the two limiting sliding grooves 8. The two slide rods 9 drive the two protective sleeves 18 to move together. The two protective sleeves 18 drive the two probes 2 to rotate. Compared with the traditional device, by rotating the adjusting block 15, medical staff can accurately adjust the distance and angle between the probes, making it more intuitive and accurate, and reducing the errors caused by improper adjustment.
[0023] Medical staff first connect the nerve probe body 1 with external equipment through a connector 17 to ensure the smooth transmission and reception of data. Check whether the probe 2 and its rubber sleeve 3 are intact to ensure safety during the operation. According to the surgical needs, observe and adjust the angle scale 6 on the rotating table 7 to an appropriate angle. Rotate the adjusting block 15, and the adjusting block 15 drives the rotating rod 16 to rotate, thereby rotating the rotating table 7. The rotation of the rotating table 7 drives the two slide rods 9 to slide in the limiting sliding grooves 8, thereby driving the two protective sleeves 18 to move together. The movement of the protective sleeves 18 drives the two probes 2 to rotate to reach the required distance and angle. Observe the silk screen scale 4 on the top of the rubber sleeve 3 and adjust the pulling-out depth of the probe 2 according to the surgical needs. Since the probe 2 is connected to the moving block 12 through a connecting wire one 10 and a connecting wire two 11, the pulling-out depth of the probe 2 can be accurately controlled by moving the moving block 12. The convex blocks 13 installed on the front and back of the moving block 12 will slide in the grooves 14 on the inner wall of the nerve probe body 1 to ensure the stability of the adjustment. After ensuring that the distance, angle, and depth of the probe 2 have been adjusted to the best state, start the surgical operation. Medical staff can fine-tune the distance, angle, and depth of the probe 2 at any time according to the surgical needs through the adjusting block 15 and the moving block 12.
[0024] Wherein, rubber sleeves 3 are respectively fixedly sleeved on the outer walls of the two probes 2, and silk screen scales 4 are respectively arranged on the tops of the two rubber sleeves 3.
[0025] By setting a silk-screened scale 4 on the top of the rubber sleeve 3, the scale markings can help medical staff more intuitively understand the pulling depth of the probe, thereby positioning and operating the probe more accurately. The design of the silk-screened scale makes the reading of the scale clearer, more durable, and not easily worn or blurred.
[0026] Among them, a nerve probe body 1 is arranged on the right side of the fixed block 5. The nerve probe body 1 has a hollow cavity structure. A connector 17 is arranged on the right side of the nerve probe body 1. Two first connecting wires 10 are fixedly installed on the left side of the connector 17. Second connecting wires 11 are respectively fixedly installed on the left sides of the two first connecting wires 10. The left ends of the two second connecting wires 11 respectively extend into the nerve probe body 1 and are fixedly connected to the nerve probe body 1. Moving blocks 12 are fixedly installed at the left ends of the two second connecting wires 11. The left sides of the moving blocks 12 are fixedly connected to the right ends of the two probes 2 and the two rubber sleeves 3.
[0027] By setting the nerve probe body 1 with a hollow cavity structure, it not only ensures the structural stability but also facilitates the arrangement and adjustment of internal components. The connector 17 is used to connect to external equipment to realize data transmission and reception. Then, through the moving block 12, it can slide along the track inside the nerve probe body 1. The rubber sleeve 3 wraps around the outside of the probe 2 to play a certain protective role.
[0028] Among them, bumps 13 are respectively fixedly installed on the front and back of the moving block 12. Grooves 14 are respectively formed on the front and back inner walls of the nerve probe body 1. The two bumps 13 are adapted to the corresponding grooves 14 and are slidably connected to them. Friction convex balls 19 are arranged on the sides of the two bumps 13 and the grooves 14 close to each other.
[0029] By fixedly installing bumps 13 on the front and back of the moving block 12 and slidably connecting them to the grooves 14 of the nerve probe body 1, the stability during the adjustment process is ensured. This design effectively prevents the moving block from shifting or shaking during sliding, thereby ensuring the accuracy and reliability of the nerve probe during the adjustment process. The introduction of the friction convex balls 19 significantly increases the friction force between the bumps 13 and the grooves 14. This means that even in the event of slight external forces or vibrations during the operation, the moving block 12 can remain stable and avoid unnecessary sliding.
[0030] The working principle and usage process of the present utility model:
[0031] Medical staff first connect the nerve probe body 1 to an external device through the connector 17 to ensure smooth data transmission and reception. Check whether the probe 2 and its rubber sleeve 3 are intact to ensure safety during the operation. According to the surgical needs, observe and adjust the angle scale 6 on the turntable 7 to an appropriate angle. Rotate the adjustment block 15, and the adjustment block 15 drives the rotating rod 16 to rotate, thereby rotating the turntable 7. The rotation of the turntable 7 drives the two sliding rods 9 to slide in the limit chute 8, thus driving the two protective sleeves 18 to move together. The movement of the protective sleeves 18 drives the two probes 2 to rotate to achieve the required spacing and angle. Observe the silk screen scale 4 on the top of the rubber sleeve 3 and adjust the pulling-out depth of the probe 2 according to the surgical needs. Since the probe 2 is connected to the moving block 12 through the connecting wire one 10 and the connecting wire two 11, the pulling-out depth of the probe 2 can be accurately controlled by moving the moving block 12. The bumps 13 installed on the front and back of the moving block 12 will slide in the grooves 14 on the inner wall of the nerve probe body 1 to ensure the stability of the adjustment. After ensuring that the spacing, angle, and depth of the probe 2 have been adjusted to the optimal state, start the surgical operation. Medical staff can fine-tune the spacing, angle, and depth of the probe 2 at any time according to the surgical needs through the adjustment block 15 and the moving block 12.
