[0002] This utility model relates to the field of medical device technology, and in particular to an electrical stimulation lead fixing device. Background Technology

[0003] Herpes zoster of the first branch of the trigeminal nerve is caused by infection with the varicella-zoster virus. It mainly affects the first branch of the trigeminal nerve (ophthalmic nerve) and causes severe neuralgia. Electrical stimulation therapy for herpes zoster of the first branch of the trigeminal nerve is an effective neuromodulation therapy. Electrical stimulation therapy involves implanting electrodes at the temples to release weak currents to stimulate the conduction bundles and sensory neurons in the spinal canal.

[0004] The leads used in electrical stimulation therapy are thin and smooth. Clinically, surgical sutures are used to suture and fix the electrical stimulation leads to the patient's outer skin, and then a fixation patch is applied.

[0005] However, the above method has the following problems: the wires in the electrical stimulation therapy are thin and smooth, and the adhesion between the fixation patch and the wires is weak, resulting in poor adhesion. The exposed wires are easily hooked and pulled by foreign objects, and the wires can easily slip out of the fixation patch, causing electrode dislocation. Utility Model Content

The first fixing band 1, the second fixing band 2, and the third fixing band 3 are made of a soft, skin-friendly elastic material. In this embodiment, the first fixing band 1, the second fixing band 2, and the third fixing band 3 are made of Lycra fabric. The first fixing band 1 is a strip-shaped structure set along the water direction, and the width of the first fixing band 1 is less than or equal to the distance between the lower end of the human nose and the upper lip.

[0024] There are two second fixing straps 2. The second fixing straps 2 are strip-shaped structures arranged along the water direction. One end of each of the two second fixing straps 2 is respectively located at the left and right ends of the first fixing strap 1. The other ends of the two second fixing straps 2 away from the first fixing strap 1 are provided with a first fixing member. In this embodiment, the first fixing member includes a first hook and loop fastener 21 and a first hook and loop fastener 22 that cooperate with each other. The first hook and loop fastener 21 is located on the front of one of the second fixing straps 2, and the first hook and loop fastener 22 is located on the back of the other second fixing strap 2.

[0025] There are two third fixing bands 3. The third fixing bands 3 are strip-shaped structures arranged in a vertical direction. The two third fixing bands 3 are respectively located at the connection between the second fixing band 2 and the first fixing band 1 on the left and right sides and extend upward. The two third fixing bands 3 are narrow at the bottom and wide at the top, and the widened parts are arranged close to each other. One of the third fixing bands 3 is provided with a first through hole 33 corresponding to the patient's electrical stimulation treatment area. The two third fixing bands 3 are provided with a second fixing member at the end away from the first fixing band 1. In this embodiment, the second fixing member includes a second hook and loop fastener 31 and a second hook and loop fastener 32 that cooperate with each other. The second hook and loop fastener 31 is located on the front of one of the third fixing bands 3, and the second hook and loop fastener 32 is located on the back of the other third fixing band 3.

[0026] Ear holes 34 are provided at the connection points of the first fixing strap 1, the second fixing strap 2 and the third fixing strap 3.

[0027] The first fixing strap 1, the second fixing strap 2, and the third fixing strap 3 are made of elastic and breathable material. In this embodiment, the first fixing strap 1, the second fixing strap 2, and the third fixing strap 3 are made of Lycra fabric.

[0028] When in working condition, the first fixing strap 1 fits against the patient's philtrum and the lower side of the cheekbone, the second fixing strap 2 fits against the back of the patient's head, and the third fixing strap 3 fits against the area near the patient's temples on both sides, the upper side of the forehead, and the front of the top of the head.

[0029] The fixation component 4 is fixed at the position corresponding to the patient's electrical stimulation site on one of the third fixation straps 3. The fixation component 4 includes a fixation body 42. The back of the fixation body 42 is fixedly connected to the third fixation strap 3 via a third fixing member. In this embodiment, the third fixing member includes a thumbtack 43 provided on the back of the fixation body 42. The needle of the thumbtack 43 passes through the back of the third fixation strap 3 and is fixedly connected to the back of the fixation body 42, thereby fixing the fixation body 42 to the third fixation strap 3.

[0030] The large-diameter and flat head of the Thumb 43 prevents pressure sores when the patient wears the device.

[0031] Two fixing posts 421 spaced apart are provided in the middle of the front of the fixing body 42. A second through hole 423 is provided at the right end of the fixing body 42, which passes through the front and back of the fixing body 42. A cover 41 is provided on the front of the fixing body 42. The cover 41 is a cavity structure with an opening on the back. A fourth fixing member is provided between the fixing body 42 and the cover 41. In this embodiment, the fourth fixing member includes a snap-fit ​​groove 422 in the middle of the front of the fixing post 421, and a snap-fit ​​post 411 on the back of the cover 41 that is snap-fitted to the snap-fit ​​groove 422. In this embodiment, the snap-fit ​​groove 422 and the snap-fit ​​post 411 are snapped together by an interference fit.

[0032] The number of fixed columns 421 is not specified. Figure 3 Appendix Figure 5 Due to limitations, the number of fixed columns 421 can be 1 or 3, etc.

[0033] The working principle of this utility model is as follows: Step 1: Attach the first fixing strap 1 to the patient's philtrum (the area between the lower end of the nose and the upper lip), and pull the two second fixing straps 2 along the lower side of the cheekbone on both sides of the patient's face towards the back of the head (the area of ​​the back of the head), and fix the two second fixing straps 2 to the back of the head of the patient through the first hook side 21 and the first hook side 22.

[0034] Step 2: Pull the two third fixation straps 3 along the left and right sides of the patient's head towards the top of the head and close to the forehead. Then, use the second hook side 31 and the second hook side 32 to attach the two third fixation straps 3 to the upper side of the patient's forehead and the front of the top of the head. Adjust the attachment position of the third fixation straps 3 to the front and back of the patient's face according to the patient's actual situation, so that the third fixation straps 3 cover the electrical stimulation wires of the patient's electrical stimulation area. At this time, the first fixation strap 1 will not easily slip upward due to the relatively protruding cheekbone and nose; the second fixation strap 2 will not easily slip upward due to the obstruction of the external occipital protuberance.

[0035] Step 3: Align the second through hole 423 with the first through hole 33, then pass the pin of the thumbtack 43 through the back of the third fixing band 3 and connect it to the back of the fixing body 42 to fix the fixing component 4 to the third fixing band 3; next, pass the electrical stimulation wire through the first through hole 33 and the second through hole 423 in sequence, and press the electrical stimulation wire... Figure 5 The figure-eight wrapping method shown is used to wrap the electrical stimulation wire between the fixing posts 421. Depending on the actual situation, the electrical stimulation wire can also be wrapped multiple times in the figure-eight direction before passing through the second through hole 423 and the first through hole 33 and hiding it on the back of the third fixing band 3. Finally, the cover 41 is placed on the front of the fixing body 42 using the snap-fit ​​post 411 and snap-fit ​​groove 422 to fix the electrical stimulation wire. The figure-eight wrapping method reduces the bending of the electrical stimulation wire and uses a complex path to fix the electrical stimulation wire to the fixing component 4. The electrical stimulation wire will not be easily pulled when it is pulled, ensuring that the electrode is in the correct position, thereby ensuring the treatment effect.
