Description

Technical Field

[0001] This utility model belongs to the field of biomedical technology, and in particular relates to an electrode clamp. Background Technology

[0002] Currently, in the process of cell electroporation using electroporation cups, clamps are required to fix the electroporation cups and make electrical connections to ensure the stability and accuracy of the electroporation effect. In existing technologies, because different models of electroporation cups have different shapes and sizes (e.g., Bio-rad's cuboid electroporation cups, Lonza's trapezoidal electroporation cups, domestically produced flat electroporation cups, and bottom-socket electroporation cups), existing electrode clamps often only fit one type of electroporation cup, failing to meet the needs of various electroporation cups. If the same clamp is used to hold different electroporation cups, the mismatch in size or shape can lead to loose clamping, causing poor contact problems, which in turn results in large impedance fluctuations in the electroporation cup under test, affecting the stability and accuracy of cell electroporation. Therefore, in existing technologies, when using electroporation cups for cell electroporation, different clamps are often customized for different models of electroporation cups, which increases operating costs and reduces operating efficiency. Summary of the Invention

[0003] This invention addresses the high cost associated with customizing different clamps for different models of electroconvulsive therapy cups in the prior art, by providing an electrode clamp compatible with multiple types of electroconvulsive therapy cups.

[0004] In view of the above technical problems, this utility model provides an electrode clamp, including a base plate, a fixing block fixedly mounted on the base plate, an adjustment assembly disposed on the base plate, and a movable block connected to the adjustment assembly and disposed opposite to the fixing block; the end face of the fixing block facing the movable block is provided with a first clamping surface having a plurality of first electrode contacts; the end face of the movable block facing the fixing block is provided with a second clamping surface having a plurality of second electrode contacts.

[0007] The movable block is connected to the slider; the lead screw is used to drive the slider, thereby causing the movable block to move closer to or away from the fixed block.

[0008] Optionally, the electrode clamp further includes a clamp housing mounted on the base plate; the clamp housing and the base plate form an accommodating space; the fixing block, the support, the lead screw, the slider and the moving block are all located within the accommodating space.

[0009] Optionally, the adjustment assembly further includes a handwheel connected to the lead screw and used to control the rotation of the lead screw; a rod hole is provided on the clamp housing at a position corresponding to the lead screw; the end of the lead screw away from the fixing block passes through the rod hole and is connected to the handwheel.

[0010] Optionally, the electrode clamp further includes a locking member disposed on the slider and used to restrict the movement of the slider; the clamp housing is provided with an operating hole; one end of the locking member away from the slider passes through the operating hole and extends out from the receiving space.

[0011] Optionally, the electrode clamp further includes a clamp cover; one end of the clamp cover is rotatably connected to the clamp housing to close or open the accommodating space.

[0016] The electrode clamp further includes a first magnetic attractor disposed at the second end of the clamp housing, and a second magnetic attractor disposed at the second end of the clamp cover and corresponding to the first magnetic attractor.

[0017] The electrode clamp provided by this utility model has a first electrode contact on the first clamping surface of the fixed block and a second electrode contact on the second clamping surface of the moving block. By setting an adjustment component to drive the moving block closer to or further away from the fixed block, the width of the clamping space between the first and second clamping surfaces can be adjusted.

[0026] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0027] It should be understood that the terms "upper", "lower", "left", "right", "front", "rear", "middle", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0028] like Figure 1 As shown, one embodiment of this utility model provides an electrode clamp, including a base plate 100, a fixing block 200 fixedly mounted on the base plate 100, an adjustment component 300 disposed on the base plate 100, and a movable block 400 connected to the adjustment component 300 and disposed opposite to the fixing block 200; the end face of the fixing block 200 facing the movable block 400 is provided with a first clamping surface 210 having a plurality of first electrode contacts 211; the end face of the movable block 400 facing the fixing block 200 is provided with a second clamping surface 410 having a plurality of second electrode contacts 411; a clamping space for clamping an electroconvulsive cup 500 is provided between the first clamping surface 210 and the second clamping surface 410; the adjustment component 300 is used to drive the movable block 400 closer to or further away from the fixing block 200 to adjust the width of the clamping space.

[0029] Understandably, the adjusting component 300 is used to drive the moving block 400 closer to or further away from the fixed block 200 to adjust the width of the clamping space, thereby achieving the clamping or releasing effect on the electroconvulsive cup 500, and enabling the electrode clamp to adapt to electroconvulsive cups 500 of different shapes and sizes. The adjusting component 300 can be configured as needed, including but not limited to components such as a lead screw 330, a worm gear, or a rack and pinion that can drive the moving block 400 to linear motion. The connection method between the fixed block 200 and the base plate 100 includes but is not limited to one or more of methods such as screwing, snap-fitting, or bonding, as long as the fixed block 200 can be securely installed on the base plate 100. Both the fixed block 200 and the moving block 400 are insulators, providing insulation to prevent current from the first electrode contact 211 and the second electrode contact 411 from flowing into the fixed block 200 or / and the moving block 400, thereby causing a short circuit or affecting the conductivity stability. The first electrode contact 211 and the second electrode contact 411 are respectively used to be electrically connected to an external power source to provide electrical energy to the electric shock cup 500 held between the first clamping surface 210 and the second clamping surface 410.

[0030] The number of the first electrode contact 211 and the second electrode contact 411 can be set according to actual conditions, for example, corresponding to the number of different shaped and sized electroshock cups 500 adapted to the electrode clamp. The number of the first electrode contact 211 can correspond to the number of the second electrode contact 411, so that the two electrodes on the electroshock cups 500 of different shapes and sizes can respectively contact the corresponding first electrode contact 211 and second electrode contact 411 to form an electrical connection. The positions of the first electrode contact 211 and the second electrode contact 411 can be set according to actual conditions, for example, corresponding to the relative positions of the two poles on the electroshock cups 500 of different shapes and sizes. As long as the electroshock cup 500 is clamped between the first clamping surface 210 and the second clamping surface 410, the two electrodes on the electroshock cup 500 can respectively contact one set of the first electrode contact 211 and the second electrode contact 411 to form an electrical connection. The width of the clamping space and the groove can be set according to actual conditions to match multiple electroshock cups 500 of different shapes and sizes. In one specific embodiment, the adjustable width of the clamping space ranges from 3mm to 50mm.

[0031] like Figure 1 and Figure 5As shown, in one embodiment, the first clamping surface 210 is provided with a first groove 212 adapted to different sizes of electroconvulsive cups, and the first electrode contact 211 is disposed on the first groove 212; the second clamping surface 410 is provided with a second groove 412 adapted to different sizes of electroconvulsive cups 500 and matching the first groove 212, and the second electrode contact 411 is disposed on the second groove 412. It can be understood that the first clamping surface 210 can be provided with first grooves 212 of different depths and widths according to different sizes of electroconvulsive cups 500. The number of first grooves 212 can be set according to actual conditions, for example, corresponding to the number of first electrode contacts 211, so that a plurality of first electrode contacts 211 can be correspondingly disposed in a plurality of first grooves 212. The second clamping surface 410 can be provided with second grooves 412 of different depths and widths matching the first groove 212 according to different sizes of electroconvulsive cups 500. The number of the second grooves 412 can be set according to the actual situation, for example, corresponding to the number of the second electrode contacts 411, so that a number of the second electrode contacts 411 can be correspondingly arranged in a number of the second grooves 412.

[0032] The electrode clamp provided in this embodiment can be used for, for example Figure 2 and Figure 5 The various types of electroshock cups 500 shown are clamped. Generally, the two opposing surfaces or the two contacts on the bottom of the electroshock cup 500 are its two opposing electrodes. Before clamping the electroshock cup 500, the electrode clamp can drive the moving block 400 away from the fixed block 200 through the adjusting component 300 to adjust the width of the clamping space to be greater than or equal to the width between the two opposing electrodes of the electroshock cup 500, so that the electroshock cup 500 can be placed in the clamping space. Further, the width of the clamping space can be adjusted to be slightly larger than the width between the two opposing electrodes of the electroshock cup 500, so that the electroshock cup 500 can be easily placed into the clamping space, while reducing the operation time when clamping the electroshock cup 500 later. After the width of the clamping space is adjusted, the electroshock cup 500 is placed in the clamping space, and the two electrodes on the electroshock cup 500 are respectively positioned opposite the first electrode contact 211 and the second electrode contact 411. Then, the adjusting component 300 drives the moving block 400 to approach the fixed block 200, so that the electric shock cup 500 abuts between the first clamping surface 210 and the second clamping surface 410. At the same time, the two electrodes on the electric shock cup 500 are electrically connected after contacting the first electrode contact 211 and the second electrode contact 411 respectively, and the electric shock cup 500 can start working.

[0033] In the electrode clamp provided by this utility model, a first electrode contact 211 is provided on the first clamping surface 210 of the fixed block 200, and a second electrode contact 411 is provided on the second clamping surface 410 of the moving block 400. By setting the adjustment component 300 to drive the moving block 400 to move closer to or further away from the fixed block 200, the width of the clamping space between the first clamping surface 210 and the second clamping surface 410 can be adjusted. This allows the electrode clamp to stably clamp various types and sizes of electroporation cups 500 in the clamping space, thereby making the first electrode contact 211 and the second electrode contact 411 contact the two opposite electrodes on the electroporation cup 500, respectively, and achieve electrical connection with the electroporation cup 500. At this time, the electroporation cup 500 stably clamped by the electrode clamp can be used for cell electroporation. The electrode clamp of this invention can be compatible with clamping different models of electric shock cups, reducing operating costs and improving operating efficiency. At the same time, the electrode clamp of this invention can also adjust the clamping force between the first clamping surface 210 and the second clamping surface 410 for clamping the electric shock cup 500, thereby ensuring the stability of the electrical conductivity when the electric shock cup 500 is clamped and improving the stability and accuracy of the electric shock effect.

[0034] like Figure 1 As shown, in one embodiment, the adjustment assembly 300 includes a support 310 fixedly mounted on the base plate 100, a slider 320 with a threaded hole, and a lead screw 330 rotatably mounted on the support 310 and passing through the threaded hole; the moving block 400 is connected to the slider 320; the lead screw 330 is used to drive the slider 320, thereby causing the moving block 400 to move closer to or away from the fixed block 200.

[0035] Understandably, the connection between the support 310 and the base plate 100 can be achieved through one or more methods, including but not limited to screwing, snap-fitting, or bonding, as long as the support 310 can be securely mounted on the base plate 100. Similarly, the connection between the movable block 400 and the slider 320 can be achieved through one or more methods, including but not limited to screwing, snap-fitting, or bonding, as long as the movable block 400 can be securely mounted on the slider 320. The lead screw 330 is mounted on the support 310 and rotatably connected to it. The rotatable connection between the lead screw 330 and the support 310 can be configured as needed. For example, a through hole can be provided on the support 310, allowing the lead screw 330 to pass through the through hole and connect to the threaded hole of the slider 320. The bottom surface of the slider 320 can be in contact with the base plate 100 to maintain contact with the base plate 100 when the lead screw 330 rotates and moves relative to it, thus preventing the slider 320 from rotating around the lead screw 330. Therefore, when the lead screw 330 rotates, it can drive the slider 320, thereby causing the moving block 400 to move closer to or further away from the fixed block 200.

[0036] like Figures 2 to 4 As shown, in one embodiment, the electrode clamp further includes a clamp housing 600 mounted on the base plate 100; the clamp housing 600 and the base plate 100 form an accommodating space; the fixing block 200, the support 310, the lead screw 330, the slider 320 and the moving block 400 are all located within the accommodating space.

[0037] Understandably, the connection between the clamp housing 600 and the base plate 100 can be one or more of the following methods, including but not limited to screwing, snap-fitting, or bonding, as long as the clamp housing 600 can be securely installed on the base plate 100. The clamp housing 600 can provide safety protection for the components within the accommodating space (such as the fixing block 200, the support 310, the lead screw 330, the slider 320, and the moving block 400).

[0038] like Figure 1 and Figure 2As shown, in one embodiment, the adjustment assembly 300 further includes a handwheel 340 connected to the lead screw 330 and used to control the rotation of the lead screw 330; a rod hole 610 is provided on the clamp housing 600 at a position corresponding to the lead screw 330; one end of the lead screw 330 away from the fixing block 200 passes through the rod hole 610 and is connected to the handwheel 340. Understandably, after the handwheel 340 is connected to the lead screw 330, it is used to control the rotation of the lead screw 330, thereby driving the slider 320 to move via the lead screw 330. The diameter of the rod hole 610 is greater than or equal to the outer diameter of the lead screw 330. The shape and size of the handwheel 340 can be set according to actual conditions. Since the end of the lead screw 330 away from the fixing block 200 passes through the rod hole 610 and is located outside the accommodating space, the handwheel 340 is located outside the accommodating space, thus facilitating the user to rotate the lead screw 330 connected to the handwheel 340 via the handwheel 340.

[0039] like Figure 1 and Figure 2 As shown, in one embodiment, the electrode clamp further includes a locking member 700 disposed on the slider 320 and used to restrict the movement of the slider 320; the clamp housing 600 is provided with an operating hole 620; one end of the locking member 700 away from the slider 320 passes through the operating hole 620 and extends out from the accommodating space.

[0040] Understandably, after the electroshock cup 500 is clamped in the clamping space and the required clamping force is achieved, the locking member 700 can lock the movement of the slider 320, thereby locking the position of the moving block 400, preventing the moving block 400 from loosening due to external force or accidental contact, which could lead to poor contact of the electroshock cup 500. The end of the locking member 700 away from the slider 320 is located outside the receiving space, facilitating user operation of the locking member 700. The locking member 700 can be configured as needed, including but not limited to a set handle screw, a locking brake block, or an electromagnetic lock, as long as it can restrict the movement of the moving block 400. In one embodiment, the locking member 700 restricts the movement of the slider 320 by limiting the rotation between the slider 320 and the lead screw 330. The locking member 700 includes a set handle screw, and the slider 320 has a screw hole corresponding to the set handle screw, with one end of the screw hole facing the lead screw 330. After the set handle screw is screwed into the screw hole, the end of the set handle facing the lead screw 330 can abut against the lead screw 330, thereby restricting the rotation between the lead screw 330 and the slider 320, and thus restricting the movement of the slider 320 and the moving block 400. In other embodiments, the locking member 700 can also restrict the movement of the slider 320 by restricting the movement between the slider 320 and the base plate 100.

[0041] like Figures 2 to 4 As shown, in one embodiment, the electrode clamp further includes a clamp cover 800; the first end of the clamp cover 800 is rotatably connected to the first end of the clamp housing 600 to cover or open the accommodating space.

[0042] Understandably, the clamp cover 800 further provides safety protection for the components within the accommodating space. A transparent window may be provided on the clamp cover 800, or the clamp cover 800 may be made directly of transparent material, allowing the user to observe the components within the accommodating space through the clamp cover 800 or the transparent window when the clamp cover 800 is closed. The first end of the clamp cover 800 can be rotatably connected to the first end of the clamp housing 600 via a butterfly hinge 810, allowing the clamp cover 800 and the clamp housing 600 to rotate at an angle of 180 degrees. The clamp cover 800 has a certain height, ensuring that even after being closed onto the clamp housing 600, it still provides the necessary height for sample loading or clamping of the electrocautery cup 500.

[0043] like Figure 1 and Figure 5As shown, in one embodiment, the movable block 400 has a guide block 420 on the side facing the fixed block 200; the fixed block 200 has a guide groove 220 corresponding to the guide block 420; the guide block 420 is inserted into the guide groove 220 to cooperate with the lead screw 330 to guide the movable block 400 towards or away from the fixed block 200. It can be understood that the direction in which the guide block 420 moves in the guide groove 220 is parallel to the axial direction of the lead screw 330, thereby avoiding interference with the lead screw 330. The guide block 420 further prevents the slider 320 from rotating around the lead screw 330 when the lead screw 330 rotates.

[0044] like Figure 1 As shown, in one embodiment, the guide block 420 is provided with a limiting post 421; the limiting post 421 is used to abut against the fixed block 200 when the width of the clamping space is a preset minimum distance threshold. Understandably, the preset minimum distance threshold can be set according to requirements. The limiting post 421 is used to limit the minimum interval distance (i.e., the preset minimum distance threshold) between the moving block 400 and the fixed block 200, to avoid direct contact between the first electrode contact 211 and the second electrode contact 411, thereby preventing a short circuit. The position of the limiting post 421 can be set according to actual conditions, as long as it can prevent direct contact between the first electrode contact 211 and the second electrode contact 411, thereby preventing a short circuit, when matching multiple electrocup cups 500 of different types and sizes.

[0045] like Figure 5 As shown, in one embodiment, the fixed block 200 is provided with a first power socket 230 electrically connected to the first electrode contact 211; the movable block 400 is provided with a second power socket 430 electrically connected to the second electrode contact 411. It can be understood that both the first power socket 230 and the second power socket 430 are used to connect an external power source and connect the external power source to the first electrode contact 211 and the second electrode contact 411. The first power socket 230 and the second power socket 430 can be banana plugs; the external power source can be connected to the first electrode contact 211 and the second electrode contact 411 by inserting a banana plug into the banana plug (i.e., the first power socket 230 and the second power socket 430). Different banana plugs can be inserted into the first power socket 230 and the second power socket 430 according to the actual circuit connection requirements. When the electrode clamp is not in use, the banana plug can be unplugged for easy storage of the electrode clamp.

[0046] like Figures 1 to 4As shown, in one embodiment, the electrode clamp further includes feet 900 or wheel sets disposed on the end face of the base plate 100 opposite to the fixing block 200. It is understood that the connection method between the feet 900 or wheel sets and the base plate 100 includes, but is not limited to, one or more of methods such as screwing, snap-fitting, or bonding, as long as the feet 900 or wheel sets can be securely mounted on the base plate 100. The feet 900 can improve the stability of the electrode clamp and prevent it from shaking. The wheel sets can drive the entire electrode clamp to move, improving the ease of movement of the electrode clamp.

[0047] like Figure 2 and Figure 3 As shown, in one embodiment, the electrode clamp further includes a first magnetic member 630 disposed at the second end of the clamp housing 600, and a second magnetic member 820 disposed at the second end of the clamp cover 800 corresponding to the first magnetic member 630. It can be understood that the opposite ends of the first magnetic member 630 and the second magnetic member 820 are opposite poles, i.e., they attract each other. The first end of the clamp cover 800 is rotatably connected to the first end of the clamp housing 600, and the first magnetic member 630 and the second magnetic member 820 are correspondingly disposed at the second end of the clamp housing 600 and the second end of the clamp cover 800, respectively, thereby allowing the clamp cover 800 to tightly cover the clamp housing 600.

[0048] The above-described 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 of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
