Abstract
Description
Technical Field
[0001] This utility model relates to the field of gastrointestinal pacing device technology, specifically to a gastric pacemaker electrode and a gastric pacemaker. Background Technology
[0002] A gastric pacemaker is a device similar to a cardiac pacemaker that uses electrical stimulation to help regulate stomach movement, thereby improving gastrointestinal function. This device is primarily used to treat conditions such as gastroparesis, where the stomach muscles cannot function properly, causing food to remain in the stomach for too long. Electrodes are key components connecting the pacemaker to the stomach tissue, responsible for transmitting electrical signals to stimulate stomach muscle contractions.
[0003] The gastric pacemaker electrode is a crucial component of a gastric pacemaker. Its primary function is to deliver electrical signals to the target tissue. These electrodes are typically made of conductive materials and require good contact with the tissue to ensure effective signal transmission. In a gastric pacemaker, the electrodes stimulate the stomach wall with minute electrical currents to help regulate stomach movement.
[0004] However, when using a gastric pacemaker electrode, it needs to be precisely placed in a specific area of the stomach, usually the antrum, which is one of the key points for controlling gastric contractions. Currently, the fixation method between the gastric pacemaker electrode and the stomach tissue is not very reliable. It is prone to loosening during long-term use, resulting in poor contact between the gastric pacemaker electrode and the stomach tissue and unstable electrical signal transmission. Utility Model Content
[0005] The purpose of this invention is to provide a gastric pacemaker electrode to alleviate the technical problems of weak reliability of the fixation method between the gastric pacemaker electrode and the gastric tissue in the prior art, which is prone to loosening during long-term use, resulting in poor contact between the gastric pacemaker electrode and the gastric tissue and unstable electrical signal transmission.
[0006] This utility model provides a gastric pacemaker electrode, comprising: an electrode body; the electrode body having an implantation portion, a suture portion, and a wiring portion; the implantation portion is located at one end of the electrode body and is capable of penetrating the outer wall of the stomach to fix the electrode body; the suture portion is located on one side of the implantation portion and is used to cooperate with a suture to press the electrode body tightly against the surface of the outer wall of the stomach; the wiring portion is located at the other end of the electrode body and is used to connect a wire.
[0007] Furthermore, the surface of the electrode body is provided with an anti-slip portion; the anti-slip portion is used to conform to the outer surface of the stomach, thereby increasing the friction between the electrode body and the outer wall of the stomach.
[0008] Furthermore, the anti-slip portion is located on one side of the implantation portion; the anti-slip portion is an anti-slip groove, and the anti-slip groove is distributed at intervals along the length direction of the electrode body.
[0009] Furthermore, the anti-slip groove is spiral-shaped and arranged around the axial direction of the electrode body.
[0010] Furthermore, the suture portion includes a fixing hole; the fixing hole penetrates the electrode body along the thickness direction of the electrode body.
[0011] Furthermore, there are multiple fixing holes; the multiple fixing holes are spaced apart and staggered.
[0012] Furthermore, the wiring part is a wire connection groove; the wire connection groove is used to accommodate and weld the wire.
[0013] Furthermore, the implanted portion tapers in a direction away from the suture portion.
[0014] Furthermore, the electrode body is made of 316LVM stainless steel.

[0030] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.
[0031] See Figure 1 The gastric pacemaker electrode provided in this embodiment includes an electrode body 100.
[0032] The electrode body 100 includes an implantation portion 110, a suture portion 120, and a wiring portion 140. The implantation portion 110 is located at one end of the electrode body 100 and can be inserted into the outer wall of the stomach to fix the electrode body 100. The suture portion 120 is located on one side of the implantation portion 110 and is used to cooperate with a suture to press the electrode body 100 firmly against the surface of the outer wall of the stomach. The wiring portion 140 is located at the other end of the electrode body 100 and is used to connect a wire.
[0033] Specifically, before use, the wiring portion 140 of the electrode body 100 in this embodiment is soldered to the wire, and the other end of the wire is connected to the control chip and the power supply. The control chip can control the electrode body 100.
[0034] After the electrode body 100 is connected to the wire, the implantation portion 110 of the electrode body 100 is inserted into the outer wall of the stomach, fixing the position of one end of the electrode body 100 with the implantation portion 110. The other end of the electrode body 100 is engaged with a suture, and the suture is used to tightly bind and fix the suture portion 120 to the outer wall of the stomach. The suture presses the suture portion 120 tightly against the outer wall of the stomach, thereby fixing both ends of the electrode body 100 and ensuring that the electrode body 100 can conform to the stomach tissue.
[0035] In this embodiment, one end of the electrode body 100 is fixed to the stomach wall by insertion, and the other end is pressed and fixed to the stomach wall by sutures, which achieves a close fit between the electrode body 100 and the stomach wall, with excellent fixation effect, and the electrode body 100 is firmly attached to the stomach tissue, and the electrical signal transmission is stable.
[0036] In this embodiment, an anti-slip portion 130 is provided on the surface of the electrode body 100. The anti-slip portion 130 is used to conform to the outer surface of the stomach, thereby increasing the friction between the electrode body 100 and the outer wall of the stomach.
[0037] In this embodiment, the surface of the electrode body 100 is provided with an anti-slip portion 130. The purpose of the anti-slip portion 130 is to reduce the friction between the electrode body 100 and the outer wall of the stomach, thereby improving the fixation stability of the electrode body 100, effectively reducing the risk of displacement or detachment of the electrode body 100 during use, and ensuring that the gastric pacemaker electrode can work continuously and effectively.
[0038] Compared to traditional suturing or clamping fixation methods, the anti-slip part 130 simplifies surgical procedures, reduces surgical time and trauma. The excellent fixation reduces discomfort caused by electrode displacement, improving the patient's treatment experience.
[0039] In this embodiment, the anti-slip portion 130 is provided on one side of the implantation portion 110. The anti-slip portion 130 is an anti-slip groove, which is distributed at intervals along the length direction of the electrode body 100.
[0040] Specifically, in this embodiment, the anti-slip grooves extend along the width direction of the electrode body 100, and there are multiple anti-slip grooves, which are spaced apart along the length direction of the electrode body 100.
[0041] It should be noted that in this embodiment, the extension direction of the electrode body 100 is the same as the insertion direction of the implantation part 110. Under this structure, the electrode body 100 can be prevented from moving along the insertion direction of the implantation part 110, which would cause the electrode body 100 to slide and cause the implantation part 110 to dislodge from the stomach wall, thus changing the position of the electrode body 100.
[0042] In this embodiment, the anti-slip groove is spiral-shaped and arranged around the axial direction of the electrode body 100.
[0043] The spiral anti-slip texture has a superior anti-slip effect and a dense texture, which can effectively increase the friction between the electrode body 100 and the stomach wall.
[0044] In this embodiment, the suture portion 120 includes a fixing hole 121. The fixing hole 121 penetrates the electrode body 100 along the thickness direction of the electrode body 100.
[0045] Specifically, after fixing the implantation portion 110 of the gastric pacemaker electrode, the gastric pacemaker electrode is pressed firmly against the outer wall of the stomach, so that the side of the gastric pacemaker electrode with spiral anti-slip texture is in close contact with the surface of the outer wall of the stomach. Then, the suture is passed through the fixation hole 121 and the gastric pacemaker electrode is sutured to the stomach wall to fix the other end of the gastric pacemaker electrode.
[0046] In this embodiment, there are multiple fixing holes 121. The multiple fixing holes 121 are arranged at intervals and staggered.
[0047] Specifically, this embodiment has two fixing holes 121, which are spaced apart and staggered along the length of the electrode body 100. With this structure, the electrode body 100 can be stitched and fixed at two points by means of sewing.
[0048] In this embodiment, the wiring portion 140 is a wire connection groove. The wire connection groove is used to accommodate and solder connecting wires.
[0049] In this embodiment, the wire connection groove is an L-shaped groove. After the wire is inserted into the L-shaped groove, the connection between the wire and the L-shaped groove is achieved by welding, resulting in a very strong connection.
[0050] In this embodiment, the implantation portion 110 tapers in the direction away from the suture portion 120.
[0051] Specifically, in this embodiment, the implantation part 110 has a pointed structure. The implantation part 110 at the end of the electrode body 100 is very sharp and can be easily inserted into the stomach wall.
[0052] Furthermore, it should be noted that the electrode body 100 is made of 316LVM stainless steel.
[0053] Specifically, 316LVM stainless steel is a material formed by vacuum melting 316L stainless steel. Vacuum melting can further improve the purity and performance of the material, giving it superior corrosion resistance and mechanical properties in certain special environments, as well as better corrosion resistance and weldability. It can also alleviate biocompatibility issues of electrode materials, avoiding tissue reactions that may result from prolonged implantation.
[0054] Furthermore, it should be noted that the thickness of the electrode body 100 should be greater than 0.2 mm and less than 0.4 mm, and the depth of the anti-slip groove should be greater than 0.05 mm and less than 0.15 mm. In this embodiment, the thickness of the electrode body 100 is 0.3 mm, and the depth of the anti-slip groove is 0.1 mm.
[0055] The gastric pacemaker provided in this embodiment includes a chip, a lead wire, and a gastric pacemaker electrode. The chip has a power supply and is externally sealed with a silicone sealant layer. One end of the lead wire is connected to the chip, and the other end is fixedly connected to the wiring portion 140 of the gastric pacemaker electrode.
[0056] Specifically, in this embodiment, the wiring portion 140 of the electrode body 100 is soldered to a wire, and the other end of the wire is connected to a chip and a power supply. The chip enables control of the electrode body 100. After the electrode body 100 is connected to the wire, the implantation portion 110 of the electrode body 100 is inserted into the outer wall of the stomach, fixing the position of one end of the electrode body 100 with the implantation portion 110. The other end of the electrode body 100 cooperates with a suture, and the suture is used to tightly bind and fix the suture portion 120 to the outer wall of the stomach. The suture presses the suture portion 120 tightly against the outer wall of the stomach, thereby fixing both ends of the electrode body 100 and ensuring that the electrode body 100 can fit closely to the stomach tissue. In this embodiment, one end of the electrode body 100 of the gastric pacemaker is fixed to the stomach wall by insertion, and the other end is pressed and fixed to the stomach wall by a suture, achieving a close fit between the electrode body 100 and the stomach wall, with excellent fixation effect, stable fit between the electrode body 100 and the stomach tissue, and stable electrical signal transmission.
[0057] In this embodiment, the chip is equipped with a battery, which can power the electrode body 100 and control the discharge of the electrode body 100 through the chip.
[0058] Furthermore, the chip can be controlled wirelessly, thus enabling remote control of the gastric pacemaker.
[0059] 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 this 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.
