Description

Technical Field

[0001] This application belongs to the field of medical device technology, and in particular relates to a test cable fixing device. Background Technology

[0002] In the field of neurostimulation, especially spinal cord stimulation, test cables and neurostimulation electrodes are commonly used in clinical surgery. These cables and electrodes are used to monitor the patient's electrical signals during surgery or to provide initial stimulation to test the effect. Chinese utility model patent CN208436256U discloses a typical implantable neurostimulation electrode, which, during surgery, needs to be used in conjunction with the electrode connection device disclosed in Chinese utility model patent CN207217919U. The method of use is shown in Figure 1. The neurostimulation electrode 30 is inserted into the adapter box of the test cable 40, and the connector of the test cable 40 is connected to a computer, allowing the electrical signals collected by the neurostimulation electrode 30 to be transmitted to the computer for processing and display. Alternatively, the test cable 40 can be connected to a neurostimulator to provide neurostimulation to the patient. During intraoperative or postoperative testing, various unpredictable movements of the patient can pull on the neurostimulation electrode 30, causing it to separate from the test cable 40 and interrupting signal transmission. Therefore, there is an urgent need for a device that can fix the test cable in place to ensure that the stimulation electrode 30 does not separate from the test cable 40 due to the patient's movement. Summary of the Invention

[0019] The technical solution of this application will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0020] This embodiment provides a test cable fixing device, as shown in Figures 2 and 3, including: a fixing sticker 1, used to fix it to the skin surface;

[0021] As shown in Figure 5, the fixing base 2 is mounted on the fixing sticker 1 and includes a base 21, a cover 22, and a connecting part 23. The cover 22 can be flipped relative to the base 21 and is fastened to the base 21 by a snap-fit ​​structure. The connecting part 23 is used to connect the base 21 and the cover 22. The base 21 includes a base plate 211 and a first protrusion 212, a second protrusion 213, and a third protrusion 214 disposed on the base plate 211. The second protrusion 213 and the third protrusion 214 form a clamping space for clamping the adapter box. A first wiring groove is formed between the first protrusion 212 and the third protrusion 214. And / or, a second wiring groove is formed between the second protrusion 213 and the connecting part 23.

[0022] In this embodiment, the test cable fixing device secures the fixing patch 1 to the patient's skin surface. When the patient moves, the test cable fixing device moves with the patient. The second protrusion 213 and the third protrusion 214 of the fixing base 2 are used to lock the adapter box. By setting the first or second wiring groove, the nerve stimulation electrode 30 can pass through the wiring groove, thereby forming a bend in the test cable 40. In this way, when the nerve stimulation electrode 30 is pulled by the patient's movement, the pulling force is first applied to the test cable fixing device, rather than directly to the connection between the nerve stimulation electrode 30 and the test cable 40, which can effectively prevent the nerve stimulation electrode 30 from falling off the test cable 40 due to the patient's movement.

[0023] As the optimal implementation method, such as Figure 6As shown, a first wiring groove and a second wiring groove are provided. The first wiring groove and the second wiring groove are located on both sides of the clamping space. This arrangement allows the nerve stimulation electrode 30 to be wrapped around the entire space, which can further improve the fixation effect and prevent the nerve stimulation electrode 30 from falling off the test cable 40.

[0024] Furthermore, the side of the first protrusion 212 facing the third protrusion 214 is an arc-shaped concave surface, and the third protrusion 214 facing the first protrusion 212 is an arc-shaped convex surface, so that the first wiring groove is an arc-shaped groove, thereby improving the clamping force on the nerve stimulation electrode 30.

[0025] Furthermore, an arc-shaped protrusion 231 is formed on the connecting part 23, and the side of the second protrusion 213 facing the connecting part 23 is an arc-shaped concave surface, so that the second wiring groove is an arc-shaped groove, thereby improving the clamping force on the nerve stimulation electrode 30.

[0026] Furthermore, the cover 22 is provided with a first clamping post 222 for extending into the first wiring groove and a second clamping post 223 for extending into the second wiring groove. When the cover 22 is fastened to the base 21, the nerve stimulation electrode 30 is clamped by the first clamping post 222 and the second clamping post 223 respectively.

[0027] The first clamping post 222 and the second clamping post 223 extend from top to bottom into the first wiring groove or the second wiring groove. The height of the first clamping post 222 and the second clamping post 223 can clamp the nerve stimulation electrode 30 but does not affect the fastening of the base 21 and the cover 22.

[0028] Furthermore, the first protrusion 212 is formed with a slot, and the cover 22 is provided with a buckle 221. The base 21 and the cover 22 are fastened together by the cooperation of the buckle structure formed by the first protrusion 212 with the slot and the buckle 221.

[0029] Furthermore, the slots are located on both sides of the first protrusion 212, and there are two latches 221, which respectively engage with the slots on both sides of the first protrusion 212. The two latches 221 and the slots make the engaging force more symmetrical and the engagement tighter.

[0030] Further, as shown in Figure 4, the fixing sticker 1 includes: foam 11 with adhesive on the bottom surface and release paper 12 attached to the bottom surface of foam 11, and the fixing seat 2 is fixed to the top surface of foam 11.

[0031] Furthermore, the fixing patch 1 is formed with a plurality of through holes 111 to allow the skin to breathe when it is applied to the skin. The release paper 12 is divided into two parts to facilitate peeling off the release paper 12. After peeling off the release paper 12, the foam 11 can be attached to the skin surface with adhesive.

[0032] Based on the above-described preferred embodiments according to this application, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this application. The technical scope of this application is not limited to the contents of the specification, but must be determined according to the scope of the claims.
