Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an electrode adapter component and a medical equipment device for delivering pulse stimulation. Background Art

[0002] At present, it is known that there are many devices that apply electrical pulse energy to the human body through electrodes and can be used to treat different diseases, such as spinal cord stimulation devices for treating chronic pain syndromes, brain pacemakers for treating neuropsychiatric diseases such as Parkinson's disease and dystonia, and cardiac pacemakers or myocardial regulators for treating cardiac dysfunction. These devices include a control host and at least one electrode wire, and the control host releases electrical energy to one end of the electrode wire, and the electrode at the other end of the electrode wire contacts the tissue to be treated, thereby releasing electrical energy to the tissue to be treated.

[0003] In order to provide more personalized treatment plans, in some improved solutions, these devices can also have multiple electrodes, one or more of which are connected to the control host as needed, and the electrical signals of the human body are sensed through the electrodes; and electrical energy is released to different parts of one or more tissues to be treated. Alternatively, an extension line needs to be added between the electrode wire and the control host. In this case, the existing practice is to use an alligator clip wire for connection, one end of the alligator clip is connected to the control host, and the other end clamps the external electrode end of the electrode wire, and the other internal electrode end of the electrode wire enters the human body to perform functions such as perception or stimulation.

[0004] With the increase in the types of electrode wires, electrode wires with multiple electrodes have appeared, such as electrode wires with 4 or 6 electrodes. Alligator clips can no longer meet current usage requirements due to the single specification and the inconvenience of not allowing the connection to come into contact with other metals. This problem becomes more and more obvious when the control host needs to connect multiple electrode wires. Therefore, how to connect multiple electrode wires to the control host is a problem that needs to be solved urgently. Utility Model Content

The electrode socket 20 is provided with at least one socket mounting hole, and a first plug-in portion 201 is provided in the socket mounting hole; the electrode wire 30 is electrically connected to the first plug-in portion 201, and the electrode wire 30 can be a wire that enters the human body, or it can be as shown in FIG. Figure 1 As shown, it is a transfer wire used to connect another wire entering the human body. When the electrode wire 30 is a transfer wire, the distance between the control host 10 and the electrode entering the human body can be further extended, which is convenient for doctors to operate. At the same time, it is also convenient to match ordinary electrode wires (whether monopolar, bipolar or quadrupole, etc.) with corresponding transfer wires, and the electrode socket 20 can be provided with multiple standardized socket mounting holes to improve the flexibility and adaptability of the transfer assembly.

[0092] In this embodiment, an electrode socket 20 is provided between the control host 10 and the electrode wire 30, and one or more socket mounting holes may be provided on the electrode socket 20. In this embodiment, there is no specific restriction on the number of socket mounting holes, and a first plug-in portion 201 is provided in each socket mounting hole. Multiple electrode wires 30 may be respectively inserted into different socket mounting holes and electrically connected to the first plug-in portion 201 in the socket mounting hole, so as to realize the electrical connection between the electrode wire 30 and the control host 10. The electrode socket 20 in this embodiment can be compatible with electrode wires 30 of various specifications to solve the problem that the alligator clip wire cannot be used for electrode wires 30 of different specifications, and the electrode socket 20 can also be used as an extension cord, but compared with the alligator clip, its connection is more firm and reliable, and each socket mounting hole can be connected to electrode wires 30 of different specifications.

[0093] In this embodiment, Figure 3 As shown, the electrode socket 20 includes a socket housing 21 and at least one buckle 22. A socket mounting hole is provided in the socket housing 21. A socket housing 21 is provided with a socket 211 communicating with the socket mounting hole. The buckle 22 is arranged in the socket mounting hole and outside the first plug-in portion 201. A portion of the electrode wire 30 is inserted into the socket 211, and the outer side wall of the electrode wire 30 is engaged with the buckle 22. In this embodiment, the electrode wire 30 can be fixedly connected to the electrode socket 20 by engaging the buckle 22, so as to prevent the electrode wire 30 from being loosened from the electrode socket 20 and improve the connection stability between the electrode wire 30 and the electrode socket 20.

[0094] In this embodiment, in order to facilitate the connection between the electrode wire 30 and the electrode socket 20, as shown in FIG. Figure 4 As shown, one end of the electrode wire 30 is provided with a second plug-in portion 40, which matches the first plug-in portion 201, and the outer side wall of the second plug-in portion 40 is provided with two grooves 41 arranged opposite to each other, as shown in FIG.

The pin of the first plug-in part 201 is inserted into the plug housing 402 of the second plug-in part 40 and electrically connected to the conductor. As long as the second plug-in part 40 is electrically connected to the first plug-in part 201 after the second plug-in part 40 is engaged with the buckle 22, the utility model does not limit the specific connection structure. When the first plug-in part 201 is a pin, the pin is disposed in the socket mounting hole instead of being exposed to the outside, and the conductor is also disposed inside the second plug-in part 40, which can effectively prevent the metal pin or conductor from being exposed to the outside, further increasing the safety of the electrical connection.

[0097] The shape of the socket 211 is waist-shaped, and the width dimension of the socket 211 is smaller than the height dimension of the socket 211. The outer wall area where the second plug-in portion 40 and the buckle 22 are engaged is also waist-shaped. The distance between the two planes 42 of the second plug-in portion 40 is smaller than the distance between the two arc surfaces 43 of the second plug-in portion 40, and the distance between the two arc surfaces 43 of the second plug-in portion 40 is larger than the width dimension of the socket 211. Figure 8 As shown in the middle mark A, when the second plug-in portion 40 is inserted into the buckle 22, the two planes 42 of the second plug-in portion 40 are located on the left and right sides of the socket 211 along the height direction of the socket 211, and the two arc surfaces 43 of the second plug-in portion 40 are located on the upper and lower sides of the socket 211 along the width direction of the socket 211, ensuring that the second plug-in portion 40 can be smoothly inserted into the buckle 22. Figure 8 As shown in Figure B, after the second plug-in part 40 rotates 90 degrees in the circumferential direction in the buckle 22, the two arc surfaces 43 of the second plug-in part 40 correspond to the width direction of the socket 211, and the distance between the two arc surfaces 43 of the second plug-in part 40 is larger than the width direction dimension of the socket 211, so that the second plug-in part 40 is limited in the socket mounting hole to achieve axial limitation of the second plug-in part 40 and prevent the second plug-in part 40 from axially escaping from the buckle 22.

[0098] It is understandable that in other embodiments, the socket 211 and the second plug-in portion 40 may also have other shapes besides the waist shape, as long as the contours of the two match and the second plug-in portion 40 can be rotated after passing through the socket 211; in other embodiments, the second plug-in portion 40 may be provided with only one arc surface 43 or other concave engaging portion, and the buckle 22 may be provided with only one corresponding protrusion 221, as long as the second plug-in portion 40 and the buckle 22 can be selectively engaged. In other embodiments, the inner contours of at least two of the multiple sockets 211 are different, for example, Figure 5As shown, when the socket housing 21 is provided with a first socket 2111, a second socket 2112, a third socket 2113 and a fourth socket 2114, the inner contour of the first socket 2111 is different from the inner contours of the second socket 2112, the third socket 2113 and the fourth socket 2114. Specifically, two engaging parts are provided on the plug-in housing 402 suitable for connecting with the first socket 2111, and the inner contour of the first socket 2111 includes a recessed part matching the two engaging parts, and the second socket 2112, the third socket 2113 and the fourth socket 2114 are suitable for connecting with the plug-in housing 402. 3 or the plug-in shell 402 connected to the fourth socket 2114 is only provided with one locking portion, and the inner contour of the first socket 2111 includes a recessed portion matching the one locking portion; or the inner contours of the first socket 2111 and the second socket 2112 are different; or the inner contours of the first socket 2111, the second socket 2112, and the third socket 2113 are different, or the inner contours of the first socket 2111, the second socket 2112, the third socket 2113 and the fourth socket 2114 are all different, so as to realize a fool-proof design during plugging. It can be understood that as long as the outer contour of the second plug-in portion 40 and the inner contour of the socket 211 are non-circular and the socket mounting hole is a cylindrical hole, when the second plug-in portion 40 passes through the socket 211 and rotates, the side wall of the socket 211 can axially limit the second plug-in portion 40 to prevent the second plug-in portion 40 from detaching from the socket 211. The utility model does not impose specific restrictions on the shape of the outer contour of the second plug-in portion 40 and the inner contour of the socket 211.

[0099] In this embodiment, the buckle 22 is an elastic buckle made of metal material, such as Fig. 9 As shown, the buckle 22 is annular and has a stop opening 222. Figure 8 As shown, a stop rib 202 is provided in the socket mounting hole, and when the buckle 22 is provided in the socket mounting hole, the stop rib 202 is located in the stop opening 222. By providing the stop opening 222 on the buckle 22 and providing the stop rib 202 in the socket mounting hole, the buckle 22 can be prevented from rotating in the circumferential direction through the cooperation between the stop rib 202 and the stop opening 222.

[0100] like Fig. 9As shown, the buckle 22 includes a spring body 223, a first buckle 224 and a second buckle 225. The spring body 223 is annular and is provided with a stop opening 222. The first buckle 224 and the second buckle 225 are arranged on the same side of the spring body 223 and are located on the same circumference. One end of the first buckle 224 is connected to the spring body 223, and the other end is a free end and has a gap with the spring body 223. One end of the second buckle 225 is connected to the spring body 223, and the other end is a free end and has a gap with the spring body 223. The protrusion 221 is arranged at the free ends of the first buckle 224 and the second buckle 225. In this embodiment, there is a gap between the free end of the first clip 224 and the spring body 223, which allows the free end of the first clip 224 to move freely in the radial direction to clamp the second plug-in part 40 or release the clamping connection with the second plug-in part 40. There is a gap between the free end of the second clip 225 and the spring body 223, which allows the free end of the second clip 225 to move freely in the radial direction to clamp the second plug-in part 40 or release the clamping connection with the second plug-in part 40.

[0101] Embodiment 2

[0102] An electrode adapter assembly, the difference between this embodiment and the first embodiment is that the buckle form is different, and the other structures are the same as the first embodiment, which will not be repeated here. The buckle 22 in the first embodiment is ideally made of elastic metal, but due to the small size of the buckle 22, the processing difficulty is relatively large, so, for example Fig.10 As shown, in this embodiment, a card plate 23 is used, and a buckle 22 is integrally formed in the card plate 23. The card plate 23 is made of non-metal, such as plastic. The card plate 23 can be processed by injection molding, 3D printing, etc., which is simple to process and has low cost.

[0103] In this embodiment, Fig.10 As shown, the electrode socket 20 also includes a card plate 23 made of non-metallic material. The card plate 23 is arranged in the socket shell 21. The card plate 23 is provided with a through hole 231 corresponding to the socket 211. The through hole 231 is provided with a buckle 22 integrally formed with the card plate 23.

[0104] Specifically, Fig.10 As shown, the socket housing 21 includes a housing body 212 and a cover plate 213 which are separately arranged. One end of the housing body 212 is provided with a socket mounting hole, in which the first plug-in portion 201 is installed. The cover plate 213 is covered on the housing body 212, and a socket 211 is provided on the cover plate 213. The card plate 23 is arranged between the cover plate 213 and the housing body 212, and a through hole 231 which is arranged one-to-one with the socket 211 is provided on the card plate 23, and a buckle 22 which is integrally formed with the card plate 23 is provided in the through hole 231. Fig.11As shown, the buckle 22 also includes a first buckle 224 and a second buckle 225. The first buckle 224 and the second buckle 225 are located on the same circumference. One end of the first buckle 224 is connected to the card plate 23, and the other end is a free end with a gap between the card plate 23. One end of the second buckle 225 is connected to the card plate 23, and the other end is a free end with a gap between the card plate 23. The protrusion 221 is provided at the free ends of the first buckle 224 and the second buckle 225. In order to prevent the card plate 23 from being clamped between the shell body 212 and the cover plate 213, causing the buckle 22 to fail to work, as shown in FIG. Fig.12 As shown, a recessed groove 2121 is provided at one end of the shell body 212 having the socket mounting hole, and the card plate 23 and the cover plate 213 are both provided in the recessed groove 2121. In this embodiment, the plug housing of the first plug part 201 can be integrally formed with the shell body 212, and the conductor of the first plug part 201 is provided in the shell body 212. In other embodiments, the first plug part 201 can also include a pin, and the second plug part 40 includes a conductor and a plug housing, and the utility model does not limit this.

[0105] Embodiment 3

[0106] An electrode adapter assembly, such as Fig.13 As shown, this embodiment further includes a stopper 50 on the basis of the first or second embodiment. The stopper 50 is arranged in the socket housing 21. A socket mounting hole is arranged in the stopper 50. The first plug-in portion 201 is arranged in the socket mounting hole. The stopper 50 can be integrally molded with a part of the first plug-in portion 201 as an insert. The inner side wall of the socket mounting hole is protruding with an arc-shaped stopper rib 51 extending in the circumferential direction, which is used to limit the rotation angle of the second plug-in portion 40. By providing the stopper 50 and providing the arc-shaped stopper rib 51 in the stopper 50, the rotation angle of the second plug-in portion 40 can be accurately controlled, so as to avoid excessive force causing the second plug-in portion 40 to rotate beyond a preset angle, so that the second plug-in portion 40 and the buckle 22 cannot be connected.

[0107] like Fig.14 As shown, the outer wall of the second plug-in portion 40 is provided with an arc recessed portion 44. After the second plug-in portion 40 is inserted into the buckle 22, one end of the arc-shaped limiting rib 51 limits the arc recessed portion 44 of the second plug-in portion 40, so that the second plug-in portion 40 cannot rotate counterclockwise, but can only rotate clockwise at a preset angle (such as 90 degrees), wherein, Fig.15 is a schematic diagram of the structure of the second plug-in portion 40 before rotation; after rotation, the other end of the arc-shaped limiting rib 51 limits the arc recessed portion 44 of the second plug-in portion 40, so that the second plug-in portion 40 can no longer rotate. At this time, Fig.16As shown, the protrusion 221 of the buckle 22 is just engaged with the groove 41 on the second plug-in part 40, and the arc surface 43 of the second plug-in part 40 is engaged with the socket 211 on the socket housing 21. When unlocking, the second plug-in part 40 rotates counterclockwise by a preset angle (such as 90 degrees), the buckle 22 withdraws from the groove 41 on the second plug-in part 40, and the second plug-in part 40 is released from the socket 211, and the second plug-in part 40 can withdraw from the buckle 22.

[0108] As a simple variation, the limiting member 50 may be omitted and an arc-shaped limiting rib may be directly provided on the inner wall of the socket mounting hole. The arc-shaped limiting rib cooperates with the outer wall of the second plug-in portion 40 to achieve precise control of the rotation direction and rotation angle of the second plug-in portion 40.

[0109] Embodiment 4

[0110] An electrode adapter assembly is disclosed. The difference between this embodiment and the first embodiment is that the plug structure provided on the electrode wire is different, and other identical structures are not described in detail here.

[0111] In this embodiment, Figures 17 to 19 As shown, the second plug-in portion 40 includes a plug housing 45 and a spring 46. The plug housing 45 is provided with an opening. The spring 46 has a connection end and a free end. The connection end of the spring 46 is provided in the plug housing 45 and connected to the plug housing 45. The free end of the spring 46 extends out of the plug housing 45 from the opening. The free end of the spring 46 has an inclined guide portion 461 and is movable along the radial direction of the electrode wire 30. When the second plug-in portion 40 is inserted into the socket 211, under the guidance of the guide portion 461, the second plug-in portion 40 is inserted into the socket 211. , the socket shell 21 at the socket 211 applies a downward force to the free end of the spring 46, so that the free end of the spring 46 moves along the radial direction of the electrode wire 30 and retracts into the plug shell 45; after the second plug-in portion 40 passes through the socket 211 and is inserted into the socket mounting hole, the free end of the spring 46 resets and moves upward to extend out of the plug shell 45, so that the free end of the spring 46 is engaged with the socket 211, so as to realize the fixed connection between the second plug-in portion 40 and the first plug-in portion 201 in a socket mounting hole of the electrode socket 20. One or more socket mounting holes can be set in the electrode socket 20, and a first plug-in portion 201 is set in each socket mounting hole. A second plug-in portion 40 with the same structure is set at one end of the electrode wire 30, so that the electrode socket 20 can connect multiple electrode wires 30 of different specifications.

[0112] Further, such as Fig.17 and Fig.18As shown, the second plug-in portion 40 further includes an unlocking block 47, which is disposed on the plug housing 45, and a portion of the unlocking block 47 contacts the spring 46, and another portion is exposed from the plug housing 45. When the unlocking block 47 moves, the free end of the spring 46 retracts into the plug housing 45, and the second plug-in portion 40 is unlocked from the first plug-in portion 201. In one embodiment, the unlocking block 47 can be configured as a button, and pressing the unlocking block 47 moves the unlocking block 47 downward, thereby driving the free end of the spring 46 to move downward into the plug housing 45.

[0113] In another embodiment, the unlocking block 47 can be moved horizontally, and the free end of the spring sheet 46 is retracted into the plug housing 45 by the cooperation between the unlocking block 47 and the spring sheet 46. Specifically, the spring sheet 46 includes a first horizontal portion 462, an inclined portion 463, a second horizontal portion 464, a vertical portion 465 and a guide portion 461 connected in sequence. The initial position of the unlocking block 47 is located above the first horizontal portion 462. When the unlocking block 47 is moved horizontally, the unlocking block 47 cooperates with the inclined portion 463 to drive the free end of the spring sheet 46 to move toward the inside of the plug housing 45, so that the spring sheet 46 is retracted into the plug housing 45. When the unlocking block 47 is moved in the reverse direction to the initial position, the free end of the spring sheet 46 is reset and extends out of the plug housing 45.

[0114] Embodiment 5

[0115] An electrode adapter assembly, the difference between this embodiment and the first embodiment is that the structure of the electrode socket 20 is different. In this embodiment, Figure 20 to Figure 23 As shown, the electrode socket 20 includes a socket shell 21 and at least one clamping member 24. The socket shell 21 is provided with a socket 211 for inserting the electrode wire 30. The socket 211 is connected to the socket mounting hole. A clamping member 24 is provided in each socket mounting hole. The clamping member 24 is a first plug-in portion 201 for realizing electrical connection with the electrode wire 30. The clamping member 24 is arranged corresponding to the socket 211. The clamping member 24 includes two conductive spring sheets 241 arranged opposite to each other. When the pin of the electrode wire 30 is fully inserted into the socket mounting hole, the pin is located between the two conductive spring sheets 241 and is clamped with the conductive spring sheets 241. At this time, the second plug-in portion of the electrode wire 30 may only include the pin.

[0116] In this embodiment, the connection between the pin of the electrode wire 30 and the conductive spring sheet 241 can not only fix the electrode wire 30 and the first plug-in portion 201, but also realize the electrical connection between the electrode wire 30 and the first plug-in portion 201. Since the second plug-in portion of the electrode wire 30 can only include the pin, there is no need to make special design for the connecting end of the electrode wire 30, and it can be used to directly connect the standard electrode wire 30 to the electrode socket 20.

[0117] Further, such as Fig.24 and Fig.25As shown, the plug pin of the electrode wire 30 includes a first plug section 31, a second plug section 32 and a third plug section 33 which are connected in sequence. The outer diameter of the second plug section 32 is smaller than the outer diameters of the first plug section 31 and the third plug section 33. When the plug pin of the electrode wire 30 is fully inserted into the socket mounting hole, the second plug section 32 is arranged between the two conductive spring sheets 241 and is clamped with the conductive spring sheets 241.

[0118] In this embodiment, the plug pin (i.e., the connecting end) of the electrode wire 30 has a variable diameter structure, which is respectively a first plug section 31, a second plug section 32, and a third plug section 33. The second plug section 32 has the smallest diameter, and a limiting groove is formed at the second plug section 32. When the connecting end of the electrode wire 30 is inserted between the two conductive spring sheets 241, the limiting groove is engaged with the two conductive spring sheets 241 to achieve the fixation of the electrode wire 30 and the clamping member 24. The step structure formed by the first plug section 31, the second plug section 32, and the third plug section 33 can be the structure of the standard electrode wire 30 itself, and there is no need to perform special design processing on the electrode wire 30.

[0119] like Fig.24 As shown, the clamping member 24 also includes a conductive portion 242, two conductive springs 241 are respectively arranged on both sides of the conductive portion 242 and are located at the same end of the conductive portion 242, and the other end of the conductive portion 242 is used to connect with the wire so as to be electrically connected to the control host 10 through the wire; the conductive spring 241 includes a first arc portion 2411 and a second arc portion 2412, one end of the first arc portion 2411 is connected to the conductive portion 242, and the other end is connected to the second arc portion 2412, the concave portion of the first arc portion 2411 faces the other first arc portion 2411 arranged oppositely, and the convex portion of the second arc portion 2412 faces the other second arc portion 2412 arranged oppositely, the second plug-in section 32 is arranged between the concave portions of the two first arc portions 2411 arranged oppositely, and the outer diameter of the second plug-in section 32 is greater than the distance between the concave portions of the two first arc portions 2411. When the connecting end of the electrode wire 30 is inserted between the two conductive springs 241, the electrode wire 30 stretches the two conductive springs 241 apart, and when the second plug-in section 32 enters between the two conductive springs 241, the two conductive springs 241 close together and fix the electrode wire 30. It is understandable that if the connecting end of the electrode wire 30 is not provided with a limiting groove (the second plug-in section 32), the electrode wire 30 can also be fixed by closing the two conductive springs 241, but the fixing effect is worse than the fixing effect with a limiting groove, the electrode wire 30 is easy to pull out, and there is no feeling of being stuck in place when plugging in, and it is impossible to know whether it is stuck in place. By setting the second plug-in section 32, it is convenient for the operator to grasp the force of plugging and unplugging and determine the plug-in state, which further facilitates the plug-in operation and improves the reliability of the connection.

[0120] Further, such as Fig. 22 and Fig.23 As shown, the electrode socket 20 also includes at least one pre-tightening spring 25, and each socket mounting hole is provided with a pre-tightening spring 25, one end of the pre-tightening spring 25 abuts against the socket housing 21, and the other end of the pre-tightening spring 25 is used to abut against the electrode wire 30; when the electrode wire 30 is engaged with the conductive spring sheet 241, the electrode wire 30 applies force to the pre-tightening spring 25, so that the pre-tightening spring 25 is compressed and deformed and is in a compressed state. When the electrode wire 30 is unengaged from the conductive spring sheet 241, the pre-tightening spring 25 is reset, and the pre-tightening spring 25 pops the electrode wire 30 outward, so that the electrode wire 30 exits the conductive spring sheet 241, thereby realizing the automatic pop-up of the electrode wire 30.

[0121] Further, such as Fig.21 As shown, the electrode socket 20 also includes a pressing plate 26; the socket housing 21 includes an upper plate 214 and a lower plate 215, the clamping member 24 is arranged between the upper plate 214 and the lower plate 215, the upper end of the second arc-shaped portion 2412 extends out of the upper plate 214, the pressing plate 26 is arranged above the upper ends of the two second arc-shaped portions 2412 and is in natural contact with the second arc-shaped portions 2412, and when the pressing plate 26 moves downward, the opening between the two second arc-shaped portions 2412 is opened, so that the two conductive springs 241 are opened outward respectively, and the electrode wire 30 is released from the conductive spring 241. Further, the pressing plate 26 may also have a pressing convex strip on one side facing the second arc-shaped portion 2412, and the pressing convex strip is arranged between the two second arc-shaped portions 2412, so that the two second arc-shaped portions 2412 can be opened by pressing the pressing plate 26.

[0122] like Fig. 20 As shown, the electrode socket 20 also includes an actuator 27 and a return spring 28. The actuator 27 is arranged in the socket housing 21 and is located above the pressure plate 26. When the actuator 27 moves toward the pressure plate 26, it drives the pressure plate 26 to move downward. The return spring 28 is arranged between the actuator 27 and the upper plate 214.

[0123] When the electrode wire 30 is connected to the clamping member 24, the actuator 27 is pressed down, and the actuator 27 drives the pressing plate 26 to move downward. The pressing plate 26 moves downward to open the opening at the upper end of the conductive spring 241, and the two conductive springs 241 are both opened outward, so that the distance between the two first arc-shaped portions 2411 is greater than the outer diameter of the first plug-in section 31. Under the action of the preload spring 25, the electrode wire 30 is pushed outward, so that the limiting groove of the electrode wire 30 is disengaged from the conductive spring 241, and the electrode wire 30 is ejected; at this time, the pressing plate 26 applies pressure to the reset spring 28, and the reset spring 28 is in a compressed state. When the actuator 27 is released, the pressing plate 26 moves upward under the action of the reset spring 28 and returns to its original position. An upper cover plate 29 is also provided above the actuator 27. The design of the upper cover plate 29 can prevent the user from accidentally touching it during operation and avoid the risk of the electrode wire 30 falling off. Furthermore, a structure that can pass through and fix a strap can be provided on the lower plate 215 to facilitate the doctor to fix it on the patient's arm or body.

[0124] The actuator 27 can be configured as a key, that is, when the actuator 27 is pressed downward, the actuator 27 drives the pressure plate 26 to move downward, and when the actuator 27 is released, the actuator 27 automatically resets, and the pressure plate 26 resets under the action of the reset spring 28. The actuator 27 can also be configured to drive the pressure plate 26 to move downward by rotation, that is, the actuator 27 is rotatably connected to the socket housing 21, and a protrusion is provided on the actuator 27. When the actuator 27 rotates toward the pressure plate 26, the protrusion presses the pressure plate 26 downward to move the pressure plate 26 downward, and when the actuator 27 rotates in a direction away from the pressure plate 26, the protrusion leaves the pressure plate 26, and the pressure plate 26 resets under the action of the reset spring 28.

[0125] In one embodiment, an actuator 27 may be provided to control the movement of multiple pressing plates 26 through the actuator 27, so as to realize the simultaneous ejection of multiple electrode wires 30. In another embodiment, multiple actuators 27 may also be provided, each actuator 27 corresponds to a pressing plate 26, and each pressing plate 26 corresponds to a clamping member 24, so as to realize independent control of the clamping member 24 and selectively eject the corresponding electrode wire 30. The actuator 27 and the pressing plate 26 may be integrally formed, and preferably, the actuator 27 and the pressing plate 26 are separately formed, so that the pressing plate 26 moves vertically downward, and the force applied to the clamping member 24 when it is stretched open is uniform as a whole.

[0126] Embodiment 6

[0127] An electrode adapter assembly, this embodiment is based on any one of the above embodiments 1 to 5, such as Fig.26As shown, the electrode lead 30 also includes an electrode adapter 60 and an adapter wire 70. The electrode adapter 60 is used to be electrically connected to another electrode lead 30a (for example, an endocardial electrode lead). One end of the adapter wire 70 is electrically connected to the electrode adapter 60, and the other end of the adapter wire 70 is electrically connected to the second plug-in portion 40. The second plug-in portion 40 is connected to the electrode socket 20. The connection between the second plug-in portion 40 and the electrode socket 20 can be the connection structure between the electrode lead 30 and the electrode socket 20 in any of the above-mentioned embodiments.

Figures 28 to 30 As shown, the locking spring piece 62 includes a vertical spring piece 621, an upper spring piece 622 and a lower spring piece 623. The vertical spring piece 621 is connected to one end of the upper spring piece 622. A through hole is provided on the vertical spring piece 621. One end of the lower spring piece 623 is connected to the other end of the upper spring piece 622. The other end of the lower spring piece 623 extends into the through hole to separate the through hole into an upper through hole 6211 and a lower through hole 6212. The locking rod 63 is rotatably arranged on the adapter housing 61 and is located above the upper spring piece 622. The locking rod 63 has a locking state and an unlocking state. Locked state; when the locking rod 63 is in the unlocked state, the upper spring piece 622 moves downward, the space of the upper through hole 6211 becomes smaller, and the space of the lower through hole 6212 becomes larger and can accommodate the electrode wire 30; when the locking rod 63 rotates in the direction of the lower spring piece 623 away from the locking spring piece 62 to the locked state, the upper spring piece 622 moves upward and resets, the space of the upper through hole 6211 becomes larger, and the space of the lower through hole 6212 becomes smaller and locks the pin of the other electrode wire to achieve a fixed connection between the other electrode wire and the electrode adapter 60.

[0129] It can be understood that in other embodiments based on any one of the above-mentioned embodiments 1 to 5, the electrode wire may also include a connecting wire and an electrode, and the electrode is used to deliver pulse stimulation.
