Description

Technical Field

[0001] The utility model relates to the technical field of electric stimulators, in particular to a fixing device for a spinal cord electric stimulator for postherpetic neuralgia. Background Art

[0002] In the Pain Management Department, a subsidiary of the Department of Anesthesiology, some patients with postherpetic neuralgia will receive spinal cord stimulator implantation. This treatment method relies on inserting an electrode cable guide wire from the body surface into the area around the patient's spinal nerves, connecting an external nerve stimulator, and adjusting parameters to control the range and intensity of the patient's pain, thereby achieving the purpose of analgesia.

[0003] Currently, there are limited means of fixing guide wires and external nerve stimulators in clinical practice. Most of them are pasted on the patient's skin and clothing with paper tape, which is not firm and does not adhere well. Therefore, there is a certain risk of electrode displacement due to poor fixation, which has an adverse effect on the patient. Therefore, a spinal cord stimulator fixation device for postherpetic neuralgia is proposed to solve the above problem. Utility Model Content

[0007] The beneficial effects of the present invention are: the outside of the stimulator can be protected by the bottom cover and the top cover, the top of the splint can be pressed to open it, and after the splint is inserted into the patient's clothes, the V-shaped spring sheet pushes the splint toward the bottom cover to fix the stimulator on the patient's clothes, and then the electrode at the bottom of the wire is inserted into the patient's skin.

[0019] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0020] Example 1, a spinal cord electrical stimulator fixing device for postherpetic neuralgia, includes a stimulator 1, a wire 2 is fixedly installed on the top of the stimulator 1, a protective fixing structure is provided on the outside of the stimulator 1, and an adsorption fixing component is provided on the outside of the wire 2.

[0021] The protective fixing structure includes a bottom cover 3 that is mounted on the outside of the stimulator 1, and a top cover 4 that is mounted on the outside of the stimulator 1 is hinged on the back of the bottom cover 3. Two support blocks 5 are fixedly installed in front of the bottom cover 3, and a splint 6 is rotatably installed between the two support blocks 5. A V-shaped spring piece 7 is fixedly installed in front of the bottom cover 3 near its top, and the surface of the V-shaped spring piece 7 abuts against the back of the splint 6. The V-shaped spring piece 7 is located between the two support blocks 5. An empty slot 8 is opened on the back of the top cover 4, and the stimulator 1 passes through the inside of the empty slot 8.

[0022] When in use, the bottom cover 3 and the top cover 4 effectively cover the stimulator 1. Pressing the top of the splint 6 can make it open. At this time, the V-shaped spring sheet 7 is compressed by force, and then the splint 6 can be inserted into the patient's clothes. After letting go, the V-shaped spring sheet 7 loses pressure and pushes the splint 6 closer to the bottom cover 3, so that the stimulator 1 can be fixed on the patient's clothes. Then, the electrode at the bottom of the wire 2 is inserted into the patient's skin. As the stimulator 1 is running, the patient's shingles can be stimulated and treated.

[0023] Example 2: This example is a further improvement on Example 1, and its details are as follows:

[0024] The adsorption and fixing component includes a clamping part 9 that is clamped to the outside of the wire 2. Two connecting plates 10 are fixedly installed on the outside of the clamping part 9. Connecting tubes 11 that pass through the front and rear sides of the two connecting plates 10 are fixedly installed inside. Airbag balls 12 are fixedly installed on the backs of the two connecting tubes 11. Suction cups 13 are fixedly installed in front of the two connecting tubes 11. The suction cups 13 are connected to the airbag balls 12 through the connecting tubes 11.

[0025] Squeezing the two airbag balls 12 can expel the air inside them, and then the two suction cups 13 are brought into contact with the patient's skin. After releasing the suction cups 13, the two suction cups 13 expand and draw out the air outside the suction cups 13, so that the wire 2 can be adsorbed on the patient's skin, which can effectively prevent the electrode of the wire 2 from shifting.

[0026] Example 3: This example is a further improvement on Example 1, and its details are as follows:

[0027] A retractable wire reel 14 is provided outside the wire 2 , and the retractable wire reel 14 is located at the midpoint of the wire 2 .

[0028] The installed retractable winding drum 14 can freely retract and release the wire 2, which can prevent the wire 2 from becoming messy.

[0029] Example 4: This example is a further improvement on Example 1, and its details are as follows:

[0030] Two lock buckles 15 are fixedly mounted on the left side of the bottom cover 3 , and two lock pins 16 are fixedly mounted on the left side of the top cover 4 . The lock buckles 15 are snap-fitted to the outside of the lock pins 16 .

[0031] The two lock buckles 15 and the two lock pins 16 are engaged to close the bottom cover 3 and the top cover 4. After the lock buckles 15 are disengaged from the lock pins 16, the bottom cover 3 and the top cover 4 can be opened, thereby facilitating maintenance of the stimulator 1.

[0032] Example 5: This example is a further improvement on Example 1, and its details are as follows:

[0033] A rubber pad 17 is fixedly mounted on the back of the clamping plate 6 , and the rubber pad 17 contacts the front of the bottom cover 3 .

[0034] The installed rubber pad 17 can play an anti-slip effect when in contact with the patient's clothes.

[0035] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
