Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an electrode wire adapter and an electrode wire adapter assembly. 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, so that the human body's electrical signals are sensed through the electrodes, and electrical energy is released to different parts of one or more tissues to be treated, or 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; due to the single specification of the alligator clip and the inconvenience of not being able to contact other metals at the connection point, it can no longer meet current usage requirements. Therefore, how to electrically connect multiple electrodes of the electrode wire to the control host in a portable, fast and secure manner is a problem that needs to be solved urgently.

[0069] In the present application, “proximal end” and “distal end” are relative positions, which refer to the two ends of a component. If one end of the component is the proximal end, the other end of the component is the distal end.

[0070] Embodiment 1

[0071] like Figure 3 As shown, the proximal end of the electrode wire 100 includes one or more conductive rings 101 that are insulated from each other along the axial direction; Figure 1 and Figure 2 As shown, the electrode wire adapter includes a shell 10 and a conductive spring clip 20. The shell 10 has a receiving cavity 11 for inserting the proximal end of the electrode wire 100. The number of the conductive spring clips 20 can be one or more, and the number of the conductive spring clips 20 is the same as the number of the conductive rings 101. The distal end of the conductive spring clip 20 is arranged in the receiving cavity 11 and extends along the axial direction of the receiving cavity 11. The distal end of each conductive spring clip 20 is used to abut against a corresponding conductive ring 101 to form an electrical connection.

[0072] It can be understood that the electrode wire 100 in this embodiment is provided with a conductive ring 101, but in other embodiments, it can also be a conductive member of other shapes, such as a quadrangular prism-shaped conductive member or an arc-shaped sheet-shaped conductive member, and the present invention does not limit this.

[0073] The electrode wire adapter of this embodiment is used to connect with the proximal end of the electrode wire 100, that is, the proximal end of the electrode wire 100 is connected with the distal end of the electrode wire adapter. Figures 19 to 21 As shown, the proximal end of the electrode wire adapter is connected to the control host through the adapter wire 200 to achieve the connection between the electrode wire 100 and the control host, so as to release electrical energy to the electrode wire 100 through the control host.

[0074] It can be understood that one end of the adapter wire 200 is connected to the electrode wire adapter, and the other end of the adapter wire 200 can be provided with a metal pin to facilitate direct electrical connection with the control host, or the other end of the adapter wire 200 can also be provided with an electrode wire adapter with the same structure or a different structure to facilitate indirect connection with the control host through other electrode wires.

[0075] like Figure 1 As shown, the proximal end of the electrode wire 100 includes one or more conductive rings 101. When there are multiple conductive rings 101, the multiple conductive rings 101 are arranged in sequence along the axial direction of the electrode wire 100, and the multiple conductive rings 101 are insulated from each other, and each conductive ring 101 is electrically connected to an electrode arranged at the distal end of the electrode wire 100.

[0076] like Figure 2 and Figure 6 As shown, the electrode wire adapter includes a housing 10 and a conductive spring 20, the distal end of the conductive spring 20 is inserted into the accommodating cavity 11 of the housing 10 and extends along the axial direction of the accommodating cavity 11, and the proximal end of the conductive spring 20 is provided with a welding foot 201 for connecting with the adapter wire 200, and the adapter wire 200 is used to be electrically connected with the control host. When the proximal end of the electrode wire 100 is assembled in the accommodating cavity 11, the distal end of each conductive spring 20 extending into the accommodating cavity 11 is respectively in contact with a conductive ring 101 to achieve electrical connection. Exemplarily, when the proximal end of the electrode wire 100 includes two conductive rings 101, the two conductive rings 101 are isolated and insulated from each other along the axial direction of the electrode wire 100, and the distal ends of the two conductive springs 20 are respectively located in the accommodating cavity 11, and one conductive spring 20 is in contact with one conductive ring 101 to achieve electrical connection, and the other conductive spring 20 is in contact with the other conductive ring 101 to achieve electrical connection.

[0077] In the present embodiment, an electrode wire adapter is provided, and the proximal end of the conductive spring sheet 20 of the electrode wire adapter can be connected to the control host through the adapter wire 200. After the proximal end of the electrode wire 100 is inserted into the outer shell 10 of the electrode wire adapter, the conductive spring sheet 20 is electrically connected to the conductive ring 101 on the electrode wire 100, so that multiple electrodes of the electrode wire 100 can be electrically connected to the electrode wire adapter, thereby realizing a quick connection between the electrode wire 100 and the control host, and the operation is convenient and the connection is firm.

[0078] Preferably, in this embodiment, when there are multiple conductive springs 20, in order to make the conductive ring 101 contact with the correct conductive spring 20, the distal ends of the multiple conductive springs 20 extend into the accommodating cavity 11 at different lengths, and the multiple conductive springs 20 are arranged at intervals along the circumference of the accommodating cavity 11, so that the multiple conductive springs 20 are isolated from each other to be insulated from each other. Exemplarily, the number of conductive rings 101 is two, and the number of conductive springs 20 is also two, such as Figure 1 As shown, the two conductive springs 20 are respectively a long conductive spring 202 and a short conductive spring 203. The length of the long conductive spring 202 extending into the accommodating cavity 11 is greater than the length of the short conductive spring 203 extending into the accommodating cavity 11. The two conductive rings 101 extend along the axial direction of the electrode wire 100. The two conductive rings 101 have different axial positions in the accommodating cavity 11. The long conductive spring 202 is electrically connected to the conductive ring 101 farther from the proximal end of the housing 10, and the short conductive spring 203 is electrically connected to the conductive ring 101 closer to the proximal end of the housing 10. This can prevent the conductive ring 101 from contacting an incorrect conductive spring 20, and facilitate doctors to quickly connect the electrode wire 100. Of course, the number of conductive springs 20 can also be set to more to match more types of electrode wires 100. At the same time, when only a monopolar wire is used, the electrode wire adapter of this embodiment can also be used.

[0079] Further, such as Figure 4 As shown, the inner side wall of the accommodating cavity 11 is provided with a mounting groove 12, and one conductive spring 20 is arranged in one mounting groove 12. When there are multiple conductive springs 20, the inner side wall of the accommodating cavity 11 is provided with multiple mounting grooves 12 at intervals along the circumferential direction, and each mounting groove 12 extends along the axial direction of the accommodating cavity 11. The conductive spring 20 is installed in the mounting groove 12, and the conductive spring 20 can be limited by the mounting groove 12. When the conductive spring 20 includes a long conductive spring 202 and a short conductive spring 203, the inner wall of the housing 10 is provided with a long conductive spring mounting groove and a short conductive spring mounting groove, which are used to install the long conductive spring 202 and the short conductive spring 203, respectively.

[0080] In this embodiment, Figure 5 As shown, the conductive spring 20 includes a spring body 21 and a conductive portion 22. The conductive portion 22 is arranged at the distal end of the spring body 21. The conductive portion 22 is provided with a protrusion 23 protruding toward the central axis of the housing 10. The protrusion 23 is used to electrically connect with the conductive ring 101. The protrusion 23 is a compensable contact on the conductive spring 20, which protrudes toward the central axis of the housing 10, so as to achieve close contact between the conductive spring 20 and the conductive ring 101, so that the conductive ring 101 and the protrusion 23 maintain a good contact state to form an effective electrical connection. The proximal end of the spring body 21 is provided with a welding foot 201 for connecting with a transfer wire 200, and the transfer wire 200 is used to electrically connect with the control host.

[0081] The conductive spring piece 20 can be made of beryllium copper and then heat-treated after molding, so that the conductive spring piece 20 has good hardness and elasticity, thereby enhancing wear resistance and loss resistance, increasing the elasticity of the conductive spring piece 20, and also increasing the contact adhesion and conductivity. In addition, the surface of the conductive part 22 can be gold-plated to further enhance the conductivity.

[0082] Further, such as Figure 5 As shown, the conductive spring piece 20 also includes an axial limiting portion 24, which is arranged on one side or both sides of the spring piece body 21 along the width direction; a limiting groove 13 is provided at the proximal end of each installation groove 12, and the shape of the limiting groove 13 matches the axial limiting portion 24. The axial limiting portion 24 is arranged in the limiting groove 13 to axially and circumferentially limit the conductive spring piece 20, so as to facilitate the installation of the conductive spring piece 20 on the inner wall of the accommodating cavity 11, and at the same time effectively avoid the damage to the conductive spring piece 20 caused by improper operation during installation.

[0083] The spring body 21 of the conductive spring 20 is arranged in the mounting groove 12, and the conductive spring 20 can be radially limited by the cooperation between the spring body 21 and the mounting groove 12; the axial limiting portion 24 of the conductive spring 20 is arranged in the limiting groove 13, and the conductive spring 20 can be axially and circumferentially limited. By limiting the conductive spring 20 to a predetermined position in the housing 10, poor electrical connection caused by the displacement of the conductive spring 20 is avoided.

[0084] Preferably, Figure 6 As shown, the distal end of the installation groove 12 is provided with a limiting structure 14 extending toward the central axis of the housing 10, and the distal end of the conductive spring 20 is located between the limiting structure 14 and the inner wall of the housing 10, and the limiting structure 14 is used to limit the conductive spring 20. The limiting structure 14 can limit the proximal end of the conductive spring 20 to prevent the conductive spring 20 from being misaligned during the installation process, causing the proximal end of the conductive spring 20 to tilt toward the central axis of the accommodating cavity 11 and affect the insertion of the electrode wire 100. Specifically, the limiting structure 14 can be a groove wall, which is formed by opening a groove on the inner wall of the housing 10, and the limiting structure 14 can also be a protruding structure, which is formed integrally with other parts of the housing 10 when the housing 10 is injection molded.

[0085] Further, such as Figures 2 to 6 As shown, the electrode wire adapter also includes a base 30, which is arranged at the proximal end of the housing 10 and is used to axially limit the conductive spring 20. Figure 7As shown, the base 30 is provided with an elastic sheet installation hole 31 for the conductive elastic sheet 20 to pass through. The distal end of the shell 10 is for the electrode wire 100 to be inserted, and the welding foot 201 provided at the proximal end of the conductive elastic sheet 20 extends from the proximal end of the shell 10. The base 30 is provided at the proximal end of the shell 10. The base 30 can abut against the axial limit portion 24 on the conductive elastic sheet 20 to further prevent the conductive elastic sheet 20 from shifting from the proximal end. The base 30 is provided with an elastic sheet installation hole 31 for the welding foot 201 of the conductive elastic sheet 20 to pass through. The base 30 is also provided with a hot melt column installation hole 32. The proximal end of the shell 10 is provided with a hot melt column 15. The hot melt column 15 on the shell 10 passes through the hot melt column installation hole 32 on the base 30. Preferably, the shell 10 and the base 30 are both made of transparent plastic material to facilitate assembly and facilitate the operator to observe the connection position and insertion depth of the electrode wire 100.

[0086] Embodiment 2

[0087] This embodiment shows another structure of the electrode wire adapter. In this embodiment, the lengths of the multiple conductive springs 20 extending into the accommodating cavity 11 are also different, which can prevent the conductive ring 101 from contacting the incorrect conductive spring 20, and facilitate the doctor to quickly implement the wire plugging. The difference between this embodiment and the above-mentioned embodiment 1 is that the structure of the conductive spring 20 is different and the fixing method of the conductive spring 20 is different. The other structures are the same as those of the embodiment 1 and will not be repeated here.

[0088] Specifically, Figure 8 As shown, the conductive spring 20 includes a spring body 21, a connecting arm 25, a cantilever 26 and two conductive parts 22, one end of the connecting arm 25 is connected to the spring body 21, and the other end of the connecting arm 25 is connected to the proximal end of the cantilever 26, one conductive part 22 is arranged at the distal end of the spring body 21, and the other conductive part 22 is arranged at the distal end of the cantilever 26, and the two conductive parts 22 are arranged oppositely and are used to be electrically connected to the same conductive ring 101. In this embodiment, each conductive spring 20 includes two conductive parts 22 arranged oppositely, and the two conductive parts 22 are electrically connected to the same conductive ring 101 of the electrode wire 100, with good contact and good conductivity, that is, the conductive spring 20 in this embodiment is a special h-shaped conductive spring, which can further improve the conductivity, ensure effective contact with the electrode wire 100, and facilitate positioning and installation.

[0089] Furthermore, the conductive part 22 is provided with a protrusion 23 protruding toward the central axis of the housing 10, the protrusion 23 is electrically connected to the conductive ring 101, and the distance between the two oppositely arranged protrusions 23 is smaller than the outer diameter of the conductive ring 101 electrically connected to the protrusion 23. The distal end of the conductive spring 20 is provided with a protrusion 23 (a compensating contact structure), which protrudes toward the central axis of the housing 10, thereby achieving close contact with the conductive ring 101 and forming an effective electrical connection. The proximal end of the conductive spring 20 is provided with a welding foot 201 for connecting to a transfer wire 200, and the transfer wire 200 is used to be electrically connected to the control host.

[0090] In this embodiment, the two conductive parts 22 of the conductive spring 20 are designed as arc-shaped cantilever structures. In the initial position, the distance between the protrusions of the two protrusions 23 on the same conductive spring 20 ( Figure 8 The H in the figure is smaller than the diameter of the conductive ring 101 electrically connected to the protrusion 23. When the conductive spring 20 contacts the conductive ring 101 of the electrode wire 100, the protrusions of the two protrusions 23 of the conductive spring 20 are pushed by the inserted conductive ring 101 to move away from each other, so the distance between the two becomes larger. At this time, the protrusions of the two protrusions 23 of the conductive spring 20 are tightly in contact with the conductive ring 101 under the action of elastic force. The protrusion 23 of the conductive spring 20 has a compensation function. When the diameter of the conductive ring 101 of the electrode wire 100 is within a certain size range (manufacturing deviations of different brands or deviations caused by various reasons), the two protrusions 23 of the conductive spring 20 can always maintain good contact with the conductive ring 101 under the action of elasticity.

[0091] Preferably, in this embodiment, Figures 9 to 11 As shown, the electrode wire adapter also includes a bracket 40 made of a non-metallic material, and the bracket 40 can play a role in assisting the fixing of the conductive spring sheet 20. The bracket 40 is arranged in the accommodating cavity 11, and an opening 41 is provided on the bracket 40; when there are multiple conductive spring sheets 20, the multiple conductive spring sheets 20 are all arranged between the bracket 40 and the inner wall of the housing 10, and the multiple conductive spring sheets 20 are staggered along the circumferential direction of the bracket 40 so that the conductive spring sheets 20 do not contact each other; or, as Fig.12As shown, at least one conductive spring 20 is disposed between the bracket 40 and the inner wall of the housing 10, and the protrusion 23 of the conductive spring 20 passes through the opening 41 to be electrically connected to the conductive ring 101, and the cantilever 26 and the protrusion 23 of at least one conductive spring 20 are disposed in the bracket 40. Exemplarily, when the conductive spring 20 includes a long conductive spring 202 and a short conductive spring 203, the long conductive spring 202 is located outside the bracket 40; the spring body 21, the cantilever 26 and the protrusion 23 of the short conductive spring 203 are installed inside the bracket 40, which can ensure the electrical safety between the long conductive spring 202 and the short conductive spring 203, and improve the reliability of the product. In this embodiment, the bracket 40 is designed inside the housing 10 to further ensure the position accuracy of the conductive spring 20 and prevent short circuits.

[0092] like Fig. 9 As shown, a recessed groove 42 is provided at the proximal end of the bracket 40, and a connecting arm 25 of a conductive spring sheet 20 is installed in a recessed groove 42; when there are multiple recessed grooves 42, the recessed depths of the multiple recessed grooves 42 along the axial direction of the bracket 40 are different, so that the multiple connecting arms 25 do not contact each other. For example, when the conductive spring sheet 20 includes a long conductive spring sheet 202 and a short conductive spring sheet 203, as shown in FIG. Fig.10 As shown, the recessed groove 42 includes a first recessed groove 421 and a second recessed groove 422. The depth of the first recessed groove 421 is greater than the depth of the second recessed groove 422. The connecting arm 25 of the long conductive spring 202 is installed in the first recessed groove 421, and the connecting arm 25 of the short conductive spring 203 is installed in the second recessed groove 422. Because a plurality of conductive springs 20 are arranged at intervals along the circumferential direction, the first recessed groove 421 and the second recessed groove 422 are also arranged staggered along the circumferential direction of the bracket 40. The recessed depths of the recessed groove 42 along the axial direction of the bracket 40 are different, so that the connecting arms 25 of the plurality of conductive springs 20 cannot contact each other, so as to ensure the electrical safety between the plurality of conductive springs 20 and improve the reliability of the product.

[0093] The electrode wire adapter of this embodiment also includes a base 30, which is arranged at the proximal end of the housing 10 to further prevent the conductive spring 20 from shifting from this end. The base 30 is provided with a spring installation hole 31 and a fixing rib 33, which can fix a conductive spring 20. The number of fixing ribs 33 is preferably more than two, and a recessed portion is further provided between each fixing rib 33, which is used to fix another conductive spring, thereby effectively avoiding contact between different conductive springs 20 through axial and circumferential misalignment. Preferably, the housing 10 and the base 30 are both made of transparent plastic material for easy assembly.

[0094] The electrode wire adapter of this embodiment can also be provided with more conductive springs 20, such as three, four or more conductive springs 20, to match more electrode wires 100. Of course, if only a single-pole single wire is used, the electrode wire adapter of this embodiment can also be used.

[0095] For example, Figures 13 to 17 As shown, when the number of the conductive springs 20 is four, they are the first conductive spring 204, the second conductive spring 205, the third conductive spring 206 and the fourth conductive spring 207, which extend into the accommodating cavity 11 and have decreasing lengths in sequence, and the four conductive springs 20 are arranged in a circumferential array along the bracket 40; the side wall of the bracket 40 is provided with a first opening 411, a second opening 412 and a third opening 413 in sequence from the distal end to the proximal end; the proximal end of the bracket 40 is provided with a first concave groove, a second concave groove, a third concave groove and a fourth concave groove with gradually decreasing concave depths along the axial direction; the first conductive spring 204 The connecting arm 25 of the first conductive spring 204 is arranged in the first recessed groove, the connecting arm 25 of the second conductive spring 205 is arranged in the second recessed groove, the connecting arm 25 of the third conductive spring 206 is arranged in the third recessed groove, and the connecting arm 25 of the fourth conductive spring 207 is arranged in the fourth recessed groove; the protrusion 23 of the first conductive spring 204 passes through the first opening 411, the protrusion 23 of the second conductive spring 205 passes through the second opening 412, the protrusion 23 of the third conductive spring 206 passes through the third opening 413, and the protrusion 23 of the fourth conductive spring 207 and the cantilever 26 are located in the bracket 40.

[0096] In this example, the shortest fourth conductive spring 207 is located in the bracket 40, and the other three conductive springs 20 are located between the bracket 40 and the inner wall of the housing 10. The bracket 40 is provided with a first opening 411 in the axial direction. 、 The second opening 412 and the third opening 413 are staggered on the circumference so that the protrusions 23 on the first conductive spring 204, the second conductive spring 205 and the third conductive spring 206 pass through the corresponding openings 41 and are electrically connected to the corresponding conductive ring 101. As a simple variation, the four conductive springs 20 can also be arranged between the bracket 40 and the inner wall of the housing 10.

[0097] In addition, if Fig.18As shown, the bracket 40 can also be set as a first bracket 401, a second bracket 402, a third bracket 403 and a fourth bracket 404 which are separately set. The first bracket 401, the second bracket 402, the third bracket 403 and the fourth bracket 404 are sealed and connected in sequence through a sealing ring 43. The first conductive spring 204 corresponds to the opening 41 on the first bracket 401, the second conductive spring 205 corresponds to the opening 41 on the second bracket 402, the third conductive spring 206 corresponds to the opening 41 on the third bracket 403, the fourth conductive spring 207 is arranged in the fourth bracket 404, and the first concave groove, the second concave groove, the third concave groove and the fourth concave groove are all located at the proximal end of the fourth bracket 404. By setting the bracket 40 in a split form, the molding of the bracket 40 can be facilitated and the molding difficulty of the bracket 40 can be reduced.

[0098] Embodiment 3

[0099] An electrode wire adapter assembly, such as Fig.19 As shown, it includes a locking mechanism 50 and the electrode wire adapter described in the above-mentioned embodiment 1 or embodiment 2. In order to prevent the electrode wire 100 from loosening due to pulling during surgery after being inserted into the electrode wire adapter, a locking mechanism 50 is further provided. The locking mechanism 50 is arranged outside the housing 10, and is used to lock the electrode wire 100 that has been inserted into the electrode wire adapter to keep the relative position of the electrode wire 100 and the electrode wire adapter unchanged.

[0100] like Figures 19 to 21 As shown, the locking mechanism 50 includes a locking block 51 and a locking rod 52, and the locking rod 52 can rotate relative to the locking block 51. An accommodating space 5101 is provided in the locking block 51, and the distal end of the housing 10 is arranged in the accommodating space 5101. An opening 5102 for the electrode wire 100 to pass through is provided at the distal end of the accommodating space 5101. The locking rod 52 is rotatably arranged on the locking block 51, and the locking rod 52 has a locking state and an unlocking state; when the locking rod 52 rotates toward the locking block 51 to the locking state, the size of the opening 5102 becomes smaller to lock the electrode wire 100, and when the locking rod 52 rotates to the unlocking state, the size of the opening 5102 becomes larger, and the electrode wire 100 can move axially. By rotating the locking rod 52 to change the size of the opening 5102, the electrode wire 100 can be locked and released.

[0101] Specifically, Fig. 22As shown, the locking block 51 includes a bottom plate 511, a top plate 512, a side plate 513 and two support frames 514; the proximal end of the top plate 512 is connected to the proximal end of the bottom plate 511 through the side plate 513, and the distal end of the top plate 512 can move up and down relative to the bottom plate 511 along the radial direction of the electrode wire 100, and an opening 5102 is formed between the distal end of the top plate 512 and the distal end of the bottom plate 511; the two support frames 514 are arranged on both sides of the distal end of the bottom plate 511, and the locking rod 52 is arranged on the side of the top plate 512 away from the bottom plate 511 and one end is rotatably connected to the two support frames 514, and the locking rod 52 is connected to the One end of the support frame 514 is provided with a protrusion 521, and the protrusion 521 is connected to the support frame 514 through a pivot rotation; in the locked state, the protrusion 521 presses downward on the top plate 512 through the first contact surface, so that the distance between the top plate 512 and the bottom plate 511 becomes smaller, and the size of the opening 5102 becomes smaller; in the unlocked state, the protrusion 521 no longer presses on the top plate 512 or reduces the pressure on the top plate 512 and contacts the top plate 512 through the second contact surface, the top plate 512 is reset, the distance between the top plate 512 and the bottom plate 511 becomes larger, and the size of the opening 5102 becomes larger. It can be understood that the protrusion 521 has a first size and a second size, the first size is the distance from the pivot to the first contact surface, and the second size is the distance from the pivot to the second contact surface, and the first size is greater than the second size. Of course, in other embodiments, in the unlocked state, the protrusion 521 may no longer contact the top plate 512, and the utility model does not limit this.

[0102] The locking block 51 is covered on the outside of the electrode wire adapter and has an opening 5102 for the electrode wire 100 to pass through. When the locking rod 52 rotates, the protrusion 521 on the locking rod 52 presses down the top plate 512, so that the opening 5102 of the locking block 51 becomes smaller, so that the locking block 51 clamps the electrode wire 100 made of elastic material, and plays a role in fixing the electrode wire 100. At this time, the protrusion 521 on the locking rod 52 is subjected to a reaction force in the locked state, and is perpendicular to the direction of the upper surface of the locking block 51, forming a torque. This torque effect forms the self-locking function of the locking mechanism 50, so that the locking rod 52 remains in the locked state. When unlocking, the locking rod 52 is rotated in the opposite direction, so that the protrusion 521 no longer presses on the top plate 512 or reduces the pressure applied to the top plate 512, and the opening 5102 becomes larger, so that the electrode wire 100 can be easily taken out. In this embodiment, the locking block 51 and the housing 10 of the electrode wire adapter can be integrally formed, or can be separately formed and then assembled. Preferably, the locking block 51 and the housing 10 are both made of transparent material, so that the operator can easily see whether the electrode wire 100 is installed in place.

[0103] In addition, the locking mechanism 50 may also be a wire buckle structure, through which the electrode wire 100 connected to the electrode wire adapter is locked.

[0104] Further, such as Fig.23 As shown, the electrode wire adapter assembly also includes a covering 60, which can be a PVC rubber-coated piece, fixedly connected to the locking block 51, covering the base 30 of the electrode wire adapter and the connection of the adapter wire 200 (the adapter wire 200 is used to connect the conductive spring 20 and the control host) to prevent the two from loosening or being damaged. The locking mechanism 50, the electrode wire adapter, the covering 60 and the adapter wire 200 together constitute the electrode wire adapter assembly.

[0105] Further, such as Fig.23 As shown, the electrode wire adapter assembly also includes a collar 70. In the locked state, the collar 70 is sleeved outside the locking rod 52 and the locking block 51, and is used to fix the locking rod 52 on the locking block 51. The collar 70 can move forward and backward. In the locked state, the collar 70 clamps the locking rod 52 and the locking block 51. The locking rod 52 itself has a self-locking function, and is tightened again by the collar 70, and the safety and reliability are enhanced. When the electrode wire 100 needs to be removed, the locking rod 52 is pressed, and the collar 70 is withdrawn to the proximal end, and no force is applied to the locking rod 52. At this time, the locking rod 52 can be opened and the electrode wire 100 can be removed.

[0106] like Fig.23 and Fig.24 As shown, the electrode wire adapter assembly further includes a reset spring 80, which is disposed in the accommodating space 5101 and is located at the far end of the accommodating space 5101. In a long-term clamping state, the top plate 512 of the locking block 51 may not be able to fully return to the initial position due to the disappearance of stress, which affects subsequent use. In this embodiment, a reset spring 80 is added in the accommodating space 5101 to ensure that the locking block 51 can always return to the initial state.
