Description

Technical Field

[0001] This utility model relates to the field of neurostimulator technology, and in particular to a neurostimulator. Background Technology

[0002] Epilepsy, depression, and post-stroke neurological damage are currently incurable diseases with no complete cure, placing a heavy burden on patients, their families, and society.

[0003] The commonly used treatment is vagus nerve stimulation, which uses electrodes connected to a stimulator to stimulate the vagus nerve. The electrical stimulation signal is transmitted to multiple parts of the brain, thereby achieving rehabilitation treatment. However, current technology requires surgery to open the neck to expose the vagus nerve and then implant stimulation electrodes into the location of the vagus nerve. When the treatment is completed or the electrodes are no longer needed, another surgery is required to remove them. This means that the patient has to endure the pain of two surgeries. In addition, the increased number of surgeries means that the patient has to bear additional risks associated with the surgery. Utility Model Content

[0004] The purpose of this invention is to provide a neurostimulator that can solve the above-mentioned technical problems.

[0005] This utility model provides a nerve stimulator, comprising:

[0006] The perforating body used to penetrate the patient's body and the push rod inserted into the perforating body during use, the push rod being movable within the perforating body;

[0007] The wire is threaded through the push rod;

[0008] The electrode is set in a receiving groove at one end of the push rod and is connected to the wire;

[0009] The protective body is installed inside the push rod and placed between the wire and the push rod;

[0010] The traction body has one end passing through the protective body and connected to the electrode, while the other end is placed outside the protective body.

[0011] As a further technical solution, a first operating handle is provided at one end of the perforated body, and the first operating handle is in communication with the perforated body.

[0012] As a further technical solution, a second operating handle is provided at the other end of the push rod, and the second operating handle is connected to the push rod.

[0013] As a further technical solution, the receiving tank includes a receiving part and a protective part, with the electrode disposed in the receiving part and protected by the protective part.

[0014] As a further technical solution, the electrode includes a first electrode and a second electrode, which are respectively connected to a wire.

[0015] As a further technical solution, the first electrode and the second electrode are connected by an insulating plate.

[0016] As a further technical solution, a sealing cap is provided at one end of the protective body, and both the wire and the traction body pass through the sealing cap.

[0017] As a further technical solution, the sealing cover is provided with a wire hole and a traction hole, with the wire passing through the wire hole and the traction body passing through the traction hole.

[0018] As a further technical solution, a sealing plate is also provided on the protective body.

[0019] As a further technical solution, the traction body includes: a traction rope, one end of which is connected to an electrode, and the other end of which is provided with a traction ring.

[0020] The technical solution of this utility model involves setting a protective body inside the push rod, placing the protective body between the wire and the push rod, and inserting a traction body inside the protective body. One end of the traction body is connected to the electrode, and the other end is placed outside the protective body. After the electrode is placed on the vagus nerve through the cooperation of the perforation body and the push rod, the vagus nerve is electrically stimulated through an external stimulator connected to the wire. At this time, the perforation body and the push rod have been withdrawn from the patient's body, while the protective body, wire, electrode, and traction body remain inside the patient's body. When the treatment is completed and the electrode needs to be removed, the other end of the traction body and the wire are pulled, causing the electrode to enter the protective body under the pull of the traction body. At the same time, the traction body, wire, and protective body are pulled. Since the electrode is placed inside the protective body, the electrode, protective body, and wire can be removed from the patient's body simultaneously. Compared with the prior art, the technical solution of this utility model can remove the electrode placed in the patient's body without multiple surgeries, reducing the number of surgeries and avoiding the additional risks to the patient.

[0033] like Figure 1-6 As shown, the present invention proposes a nerve stimulator comprising:

[0034] The invention comprises a perforating body 1 and a push rod 2 inserted into the perforating body 1 during use. The push rod 2 is movable within the perforating body 1. During use, the perforating body 1 is inserted into the patient's body. A wire 3 is inserted into the push rod 2. An electrode 4 is disposed in a receiving groove 21 at one end of the push rod 2 and connected to the wire 3. Specifically, after the perforating body 1 is inserted into the patient's body, one end of the push rod 2 is inserted into the perforating body 1 and positioned at the location of the vagus nerve. Since the electrode 4 is located in the receiving groove 21 at one end of the push rod 2, the push rod 2 moves along with the electrode 4, positioning the electrode 4 at the location of the vagus nerve. After the electrode 4 is positioned at the vagus nerve, the push rod 2 and the perforating body 1 are withdrawn from the patient's body, thereby placing the electrode 4 and the wire 3 at the vagus nerve position within the patient's body. In addition, in this invention, a protective body 5 is inserted into the push rod 2 and positioned between the wire 3 and the push rod 2. Between rods 2; one end of traction body 6 passes through protective body 5 and connects to electrode 4, while the other end is placed outside protective body 5; since protective body 5 is inserted inside push rod 2, when push rod 2 and perforated body 1 are withdrawn from the patient's body, protective body 5 and electrode 4 need to remain in the patient's body simultaneously; of course, since one end of traction body 6 is connected to electrode 4, traction body 6 will also remain in the patient's body; it is connected to external stimulator through wire 3, and the external stimulator provides the required electrical energy to electrode 4, enabling electrical stimulation therapy of the vagus nerve; it should be noted that in this utility model, both protective body 5 and traction body 6 are made of flexible material, so they can adapt to the patient's activities and avoid causing the patient pain or discomfort; in addition, a scale is provided on the outer surface of perforated body 1, and during use, the depth of perforated body 1 inserted into the patient's body can be known through the scale, thereby better controlling perforated body 1;

[0035] After the treatment is completed, grasp the exposed part of the protective body 5 and pull the other end of the traction body 6. At this time, since the electrode 4 is connected to one end of the traction body 6, under the action of external force, the electrode 4 separates from the vagus nerve and enters the protective body 5. Then, pull the protective body 5, the lead wire 3 and the traction body 6 at the same time to pull them out of the patient's body, and then remove the electrode 4. It should be noted that when removing the protective body 5, the lead wire 3 and the traction body 6, the patient needs to be checked to avoid damage to the adjacent skin or muscles during removal.

[0036] like Figure 1 As shown in Figure 2, to better operate the perforated body 1, a first operating handle 11 is preferably provided at one end of the perforated body 1. Since the push rod 2 needs to be inserted into the perforated body 1, the first operating handle 11 is connected to the perforated body 1. This facilitates the operation of the perforated body 1 without affecting the insertion of the push rod 2 into the perforated body 1. Of course, the push rod 2 also needs to be operated by hand. To better operate the push rod 2, a second operating handle 22 is preferably provided at the other end of the push rod 2. Since the wire 3 and the protective body 5 need to be inserted into the push rod 2, it is necessary to ensure that the second operating handle 22 is connected to the push rod 2. This improves the operability of the push rod 2 without affecting the installation of the wire 3 and the protective body 5. Figure 4 and 5 As shown, the electrode 4 is placed in the receiving groove 21 during the process of entering the patient's body. In this utility model, the receiving groove 21 includes a receiving part 211 and a protective part 212. The electrode 4 is placed in the receiving part 211 and protected by the protective part 212. Specifically, when the push rod 2 is placed in the perforated body 1, the electrode 4 is conveyed in the receiving part 211. When one end of the push rod 2 enters the patient's body, it can be pushed away by the protective part 212 to prevent the internal tissue from contacting the electrode 4 and ensure that the electrode 4 can reach the location of the vagus nerve.

[0037] It should be noted that electrode 4 needs to be placed inside the receiving part 211 to effectively protect electrode 4 from contact with tissues inside the patient's body; wherein, electrode 4 includes a first electrode 41 and a second electrode 42, the first electrode 41 and the second electrode 42 being connected to the wire 3 respectively; in this utility model, the first electrode 41 is a positive electrode and the second electrode 4 is a negative electrode, and the vagus nerve is electrically stimulated through the cooperation of the first electrode 41 and the second electrode 42; in addition, both the first electrode 41 and the second electrode 42 are connected to the traction body 6 and can move under the action of the traction body 6; as Figure 5As shown, to ensure the stability between the first electrode 41 and the second electrode 42, preferably, the first electrode 41 and the second electrode 42 are connected by an insulating plate 43. On the one hand, the first electrode 41 and the second electrode 42 are connected by the insulating plate 43 to form a whole, so that the first electrode 41 and the second electrode 42 can move simultaneously when pulled by the traction body 6. On the other hand, since the insulating plate 43 is made of insulating material, it avoids the conduction between the first electrode 41 and the second electrode 42, thus not affecting the use of the first electrode 41 and the second electrode 42.

[0038] After electrode 4 is placed inside the patient's body, the perforated body 1 and push rod 2 are removed, and then the protective body 5 is placed inside the patient's body. Because it is necessary to ensure that the traction body 6 and the lead wire 3 can move within the protective body 5, there will be space inside the protective body 5. However, when the protective body 5 is placed inside the patient's body, foreign objects may enter the protective body 5 and then the patient's body. Therefore, in this invention, if... Figure 6 As shown, one end of the protective body 5 (the end placed outside the patient's body) is provided with a sealing cap 51, and both the lead wire 3 and the traction body 6 pass through the sealing cap 51. This effectively prevents foreign objects from entering the protective body 5 during use. In addition, the sealing cap 51 is provided with a wire hole 52 and a traction hole 53. The lead wire 3 passes through the wire hole 52, and the traction body 6 passes through the traction hole 53. Thus, even when the sealing cap 51 is connected to the protective body 5, the lead wire 3 and the traction body 6 can still be installed without affecting their operation. Of course, due to the presence of the wire hole 52 and the traction hole 53, there will still be space in the wire hole 52 and the traction hole 53. Therefore, during use, it is necessary to use sterilized cotton balls or other medical supplies to block the wire hole 52 and the traction hole 53, and remove the cotton balls before removing the electrode 4.

[0039] like Figure 3 As shown, a sealing sheet 54 is also provided on the protective body 5. When the perforated body 1 and the push rod 2 are removed, the protective body 5 comes into contact with the patient's skin and muscles. Since a section of the protective body 5 needs to be placed outside the skin, during subsequent use, the intersection of the skin perforation position and the protective body 5 will repeatedly come into contact with the patient's movements, increasing the patient's pain. Therefore, in this utility model, the sealing sheet 54 is placed at the intersection of the skin perforation position and the protective body 5. The sealing sheet 54 is fixedly set on the protective body 5, and an adhesive layer is provided on the side of the sealing sheet 54 adjacent to the skin. By adhering the sealing sheet 54 to the skin, the range of motion of the protective body 5 can be effectively limited when the patient moves, which can effectively reduce the contact between the protective body 5 and the skin perforation position and relieve the patient's pain.

[0040] like Figure 3As shown, the traction body 6 includes a traction rope 61 and a traction ring 62. One end of the traction rope 61 is connected to the electrode 4, and the other end is equipped with a traction ring 62. Specifically, there are two traction ropes 61, which are connected to the first electrode 41 and the second electrode 42 respectively. The other ends of the two traction ropes 61 are connected to the traction ring 62 respectively. When the first electrode 41 and the second electrode 42 are used to perform electrical stimulation therapy on the patient, the traction ring 62 is placed outside the protective body 5 and does not perform any operation. When it is necessary to remove the electrode 4, the traction ring 62 is pulled, which drives the traction rope 61 to move inside the protective body 5 and pulls the first electrode 41 and the second electrode 42, so that the first electrode 41 and the second electrode 42 are pulled into the protective body 5. After the first electrode 41 and the second electrode 42 enter the protective body 5, the protective body 5, the wire 3 and the traction ring 62 are pulled out of the patient's body at the same time, thereby realizing the removal of the electrode 4.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
