Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to an electrode clip. Background Technology

[0002] Body composition analysis is a health "code" or window into one's health, providing a clearer understanding of one's own health status. Using bioelectrical impedance analysis, it precisely measures segmental body composition, reflecting changes in extracellular water, fat, protein, and inorganic salts in different body segments, and assessing nutritional status, degree of edema, and visceral fat area. Measurement can be performed standing, sitting, and lying down.

[0003] Bioimpedance contains rich pathological and physiological electrical signals in the human body, which can serve as a primary basis for medical personnel to accurately diagnose patient symptoms and treat diseases. A human body impedance model is constructed, and human body impedance is collected and analyzed using electrodes to obtain various component parameters of the human body. A low-frequency signal is generated and injected into the human body through a signal generation circuit. The voltage generated by the current flowing through the human body is detected using an amplitude detection circuit. The impedance information of different segments of the human body is measured using a segmented detection method. The correlation between the data and human body component parameters is analyzed to obtain various component parameters of the human body and display the measurement results. The above content is from "Design of a Bioimpedance Human Body Composition Analyzer Based on Four-Electrode Multi-Frequency Scanning" 2024, 47(12):45.

[0004] In existing technology, the clips used for measuring body composition are electrocardiogram (ECG) electrode clips. Their main structure includes an upper clip, a lower clip, a rotating shaft, a torsion spring, electrode pads, and leads. The upper and lower clips are rotatably mounted on the rotating shaft. The portions of the upper and lower clips behind the rotating shaft are the gripping parts, and the portions in front of the rotating shaft are the clamping parts. The torsion spring is fitted onto the rotating shaft, with one end connected to the gripping part of the upper clip and the other end connected to the gripping part of the lower clip. However, ECG electrodes have the following drawbacks: the clamping force of the torsion spring is insufficient, leading to easy loosening and insecure fixation.

[0005] Currently, when measuring the styloid process of the ulna and the ankle bones, it is necessary for the electrodes to make full contact. The impedance value of the characteristic area is calculated using the voltage difference obtained from the electrodes. If the electrodes make poor contact or fail to make contact during the process, it may lead to measurement interruption or reduce the reliability of the data.

[0006] Currently used electrode clamps mostly employ a spring-loaded clamping mechanism, with three clamping force settings (weak, medium, and strong). This is not only difficult to adjust, but even at the highest setting, it still fails to adequately clamp the measuring area. This structure cannot provide effective clamping force, and excessive force on the clamping end can cause the shaft to detach and fail. Summary of the Invention

[0007] In order to at least partially solve the problems existing in the prior art, the present invention provides an electrode clip, the technical solution of which is as follows.

[0008] The electrode clamp includes a first clamp, a second clamp, an electrode plate, and a switching mechanism. The first clamp and the second clamp are rotatably connected, and an electrode plate is installed on the inner side of at least one of the first clamp and the second clamp. The switching mechanism has an operating member, a pushing member, and a locking component. The operating member is configured to rotate when subjected to pressure in a first direction. The pushing member is connected to the operating member and is movable in a second direction when the operating member rotates. The locking component is connected to the pushing member and is configured to switch between a locked state and an unlocked state as the pushing member moves. The rotation between the first clamp and the second clamp is restricted when the locking component is in the locked state.

[0009] The electrode clamp provided by this invention can clamp and measure human body segments through a rotating connection between a first clamp and a second clamp. By ensuring full contact between the electrode plates and the human body segments, the impedance value of the characteristic parts is calculated using the voltage difference obtained from the electrode plates. Switching the locking component to the locked state restricts the rotation between the first and second clamps, providing a stable and effective clamping solution. This allows for clamping human body segments of various sizes, resulting in better clamping of the measurement area. Furthermore, switching the locking component to the unlocked state allows for easy disassembly of the electrode clamp. In the electrode clamp, when the operating member is pressed in a first direction, it rotates and drives the pushing member to move along a second direction, thereby switching the locking component between the locked and unlocked states. Since the first and second directions are different, the pushing member can be designed to have a longer length along the second direction, resulting in better stability of the pushing member and a more stable overall structure. In addition, the operating component is connected to the pushing component, and the locking component is connected to the pushing component. The entire component can be reset by resetting only one of the operating component, the pushing component, and the locking component. This makes it easier to switch the locking component to the unlocked state and remove the electrode clip.

[0010] For example, the first clamp has a first gripping portion that encloses a receiving cavity, the operating member has a first rotating end located inside the receiving cavity and an operating end located outside the receiving cavity, and a pushing member is connected to the first rotating end and is located inside the receiving cavity.

[0011] For example, the first gripping part has an opening, and the operating end moves into the receiving cavity through the opening when pressed.

[0012] For example, the first gripping part has a bottom housing opposite to the opening, and a limiting sleeve is provided on the bottom housing. The pusher passes through the limiting sleeve so that it is limited to being movable in the second direction when the operating member rotates.

[0013] For example, a connector is provided in the cavity, the connector having a first end and a second end, and an operating member having a connecting part between the first rotating end and the operating end. The first end and the connecting part are rotatably connected via a first shaft, and the second end is rotatably connected to the limiting sleeve.

[0014] For example, the operating end is connected to the bottom housing via an elastic element, which is used to apply a restoring force acting in a first direction to the operating end.

[0015] For example, a positioning sleeve extending in a first direction is provided on the bottom housing, an elastic element is sleeved on the positioning sleeve, and a positioning post is provided on the side of the operating end facing the receiving cavity. The positioning post is at least partially inserted into the positioning sleeve and is movable relative to the positioning sleeve.

[0016] For example, the end of the pusher that is away from the locking assembly is rotatably connected to the first rotating end via a second shaft.

[0017] For example, the locking assembly has a locking member and a locking engagement member, the pusher member is rotatably connected to the locking member via a third axis, the second clamp has a second gripping portion disposed opposite to the first gripping portion, and the locking engagement member is disposed on the second gripping portion.

[0018] For example, the locking member has an arc-shaped body and a plurality of first teeth disposed on the arc-shaped body, and the locking member has a plurality of second teeth that mesh with the first teeth.

[0019] A series of simplified concepts are introduced in the description of the invention, which will be further explained in detail in the detailed description section. This description is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

Detailed Implementation

[0023] In the following description, numerous details are provided to enable a thorough understanding of the invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the invention, and that the invention can be practiced without one or more of these details. Furthermore, to avoid obscuring the invention, some technical features well-known in the art have not been described in detail.

[0024] This invention provides an electrode clip. See also: Figure 1, Figure 2 , Figure 3 and Figure 4 The electrode clamp 1 may include a first clamp 10, a second clamp 20, an electrode plate 50, and a switching mechanism 60. The first clamp 10 and the second clamp 20 are rotatably connected, and the electrode plate 50 may be mounted on the inner side of at least one of the first clamp 10 and the second clamp 20. The first clamp 10 and the second clamp 20 can be rotatably connected in any suitable manner, and the present invention does not limit the specific form of the rotatable connection between the first clamp 10 and the second clamp 20. For example, see [reference 1] Figure 5 and Figure 6The first clamp 10 can be rotatably connected to the second clamp 20 via a pivot 70. The first clamp 10 may include a first gripping portion 11 and a first clamping portion 12, and the second clamp 20 may include a second gripping portion 21 and a second clamping portion 22. The pivot 70 can be connected between the first gripping portion 11 and the first clamping portion 12 on the first clamp 10, and also between the second gripping portion 21 and the second clamping portion 22 on the second clamp 20. The first clamp 10 and the second clamp 20 can rotate about the pivot 70, thereby allowing them to rotate relative to each other. In an embodiment not shown, the first clamp 10 may be provided with a rotating shaft, and the second clamp 20 can be rotatably connected to this rotating shaft to be rotatable relative to the first clamp 10. Electrode plates 50 may be mounted on the inner side of at least one of the first clamp 10 and the second clamp 20. This can be done on the inner side of the first clamp 10, the second clamp 20, or both. For example, the electrode plate 50 may be mounted on the inner side of the first clamp 10 at any suitable position. When the electrode clamp 1 grips the measurement area, the electrode plate 50 mounted on the inner side of the first clamp 10 can fully contact the measurement area. Alternatively, the electrode plate 50 may be mounted on the inner side of the first clamping part 12. Similarly, the electrode plate 50 may be mounted on the inner side of the second clamp 20 at any suitable position. When the electrode clamp 1 grips the measurement area, the electrode plate 50 mounted on the inner side of the second clamp 20 can fully contact the measurement area. For example, the electrode plate 50 can be installed inside the second clamping part 22. For the electrode clamp 1 shown in the figure, the first gripping part 11 can be opposite to the second gripping part 21, and the first clamping part 12 can be opposite to the second clamping part 22. The inner side of the first clamping part 12 can be the side of the first clamping part 12 facing the second clamping part 22, and the inner side of the second clamping part 22 can be the side of the second clamping part 22 facing the first clamping part 12. When the electrode clamp 1 clamps the measuring part, the first clamping part 12 and the second clamping part 22 can cooperate to clamp the measuring part. The electrode plate 50 can be pressed tightly against the measuring part. The electrode plate 50 inside the first clamping part 12 and / or the electrode plate 50 inside the second clamping part 22 makes full contact with the measuring part, and the impedance value of the measuring part can be calculated using the voltage difference obtained from the electrode plate 50. The contact area of ​​the electrode 50 can be designed according to actual needs so that the electrode 50 can have a suitable contact area. In this way, when the electrode clip 1 is used, it can achieve a higher signal amplitude and a higher current and voltage value through the electrode 50, thereby obtaining a better measurement effect. At the same time, the electrode 50 having a suitable contact area means that the electrode 50 can have a correspondingly suitable weight, thereby preventing the electrode 50 from falling off due to excessive weight.

[0025] It is understandable that, taking the use of electrode clip 1 to measure the styloid process of the ulna as an example, electrode clip 1 can clamp the side of the styloid process of the ulna. That is to say, the clamping of the measurement site by electrode clip 1 is not strictly limited to clamping the measurement site. Rather, it can be moved to a certain position according to the actual needs of the measurement. For example, when it is necessary to clamp the measurement site from the side to measure the measurement site, electrode clip 1 can be clamped from the side of the measurement site.

[0026] Among them, see reference Figure 7 , Figure 8 , Figure 9 and Figure 10 The switching mechanism 60 may have an operating member 61, a pushing member 62, and a locking assembly 63. The operating member 61 may be configured to rotate under pressure in a first direction (direction XX in the figure). The pushing member 62 may be connected to the operating member 61 and movable along a second direction (direction YY in the figure) when the operating member 61 rotates. The locking assembly 63 may be connected to the pushing member 62 and may be configured to switch between a locked and unlocked state as the pushing member 62 moves. The rotation between the first clamp 10 and the second clamp 20 is restricted when the locking assembly 63 is in the locked state. The pushing member 62 may be connected to the operating member 61 by a hinge, a pivot connection, or any other suitable means. Under pressure in the first direction XX, the operating member 61 can rotate, and the rotation of the operating member 61 can drive the pushing member 62 to move along the second direction YY. Figures 2-9In any of the attached figures, direction XX indicates the first direction of electrode clamp 1 in the state shown, and direction YY indicates the second direction of electrode clamp 1 in the state shown. It can be understood that the first and second directions can change when the first clamp 10 and the second clamp 20 rotate relative to each other. The first and second directions are used only as a distinction; they can be at any angle. Since the first and second directions are two different directions—that is, the direction of the pressing force acting on the operating member 61 and causing it to rotate is different from the direction of movement of the pushing member 62—a reasonable structural design can allow the pushing member 62 to have a longer length in its movable direction, i.e., in the second direction YY. This improves the stability of the pushing member 62, especially when it connects the operating member 61 and the locking assembly 63, and plays a transmission role. A more stable pushing member 62 leads to a more stable overall transmission, and thus a more stable switching of the locking assembly 63 between the locked and unlocked states. When the locking assembly 63 is in the unlocked state, the relative rotation between the first clamp 10 and the second clamp 20 is unrestricted. At this time, the electrode clamp 1 can be removed by rotating the first clamping part 12 and the second clamping part 22 in a direction away from each other. When the locking assembly 63 is in the locked state, the relative rotation between the first clamp 10 and the second clamp 20 can be locked in any suitable manner. For example, see... Figure 8 and Figure 9 In the illustrated embodiment, the locking component 63 may include a pawl-shaped locking member 631 and a ratchet-shaped locking engagement member 632. The locking member 631 is rotatably connected to the pusher 62, and the pusher 62 may be disposed on the first gripping portion 11. The locking engagement member 632 may be fixedly connected to the second gripping portion 21. Figure 8 The locking assembly 63 shown is in a locked state. At this time, the pawl-type locking member 631 and the ratchet-type locking engagement member 632 engage to restrict the relative rotation of the first clamp 10 and the second clamp 20. Specifically, the restriction on the relative rotation of the first clamp 10 and the second clamp 20 is such that the first clamping part 12 and the second clamping part 22 can only rotate in a direction closer to each other, and cannot rotate in a direction further away from each other. Figure 9 The locking assembly 63 is in the unlocked state, with the pawl-type locking member 631 disengaged from the ratchet-type locking engagement member 632, and the relative rotation of the first clamp 10 and the second clamp 20 is unrestricted. A pressing force along the first direction XX acts on the operating member 61, causing it to rotate and drive the pushing member 62 to move along the second direction YY. The movement of the pushing member 62 causes the pawl-type locking member 631 to disengage from the ratchet-type locking engagement member 632, meaning the locking assembly 63 is unlocked. Figure 8The state shown transitions to, as Figure 9 The state shown enables the locking component 63 to switch from the locked state to the unlocked state.

[0027] The electrode clamp 1 provided by this invention can clamp and measure human body segments through a first clamp 10 and a second clamp 20 connected by rotation. The electrode plate 50 makes full contact with the human body segment, and the impedance value of the characteristic part is calculated using the voltage difference obtained from the electrode plate 50. By switching the locking component 63 to the locked state, the rotation between the first clamp 10 and the second clamp 20 is restricted. At this time, the electrode clamp 1 provides stable and effective clamping, enabling clamping of human body segments of various sizes, thus allowing for better clamping of the measurement area. Furthermore, switching the locking component 63 to the unlocked state allows for easy disassembly of the electrode clamp 1. In the electrode clamp 1, when the operating member 61 is subjected to pressure in the first direction XX, it rotates and drives the pushing member 62 to move along the second direction YY, thereby switching the locking component 63 between the locked and unlocked states. Since the first direction XX and the second direction YY are two different directions, the pushing member 62 can be designed to have a longer length along the second direction YY, thus improving the stability of the pushing member 62 and making the overall structure more stable. In addition, the operating member 61 is connected to the pushing member 62, and the locking component 63 is connected to the pushing member 62. The entire system can be reset by resetting any one of the operating member 61, the pushing member 62 and the locking component 63. This makes it easier to switch the locking component 63 to the unlocked state and disassemble the electrode clip 1.

[0028] In one embodiment of the present invention, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The first clamp 10 may have a first gripping portion 11, which may enclose a receiving cavity 111. The first gripping portion 11 may have any shape that is easy to grip, and the receiving cavity 111 may be formed inside the first gripping portion 11. Exemplarily, the first gripping portion 11 may have a cover 112 and a bottom shell 113, which may enclose the receiving cavity 111. The operating member 61 may have a first rotating end 611 located inside the receiving cavity 111 and an operating end 612 located outside the receiving cavity 111. A pushing member 62 may be connected to the first rotating end 611 and may be located inside the receiving cavity 111. When a pressing force along the first direction XX is applied to the operating member 61, the pressing force may be applied to the operating end 612 located outside the receiving cavity 111. In this electrode clamp 1, since the pusher 62 and the first rotating end 611 are both located inside the receiving cavity 111, better protection can be provided for the pusher 62, the first rotating end 611, and the connection between the pusher 62 and the first rotating end 611, thus improving overall stability. Moreover, since the operating end 612 is located outside the receiving cavity 111, it is easier to apply pressure to the operating end 612 to rotate the operating part 61, making the electrode clamp 1 more convenient to use.

[0029] For example, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The first grip portion 11 may have an opening 1121, through which the operating end 612 can move into the receiving cavity 111 when subjected to pressure. Exemplarily, the first grip portion 11 may have a cover 112, which can seal the receiving cavity 111 inside the first grip portion 11, and the opening 1121 can be provided on the cover 112. The receiving cavity 111 can communicate with the outside of the first grip portion 11 through the opening 1121. Preferably, the opening 1121 may have a form that matches the operating end 612, so that the operating end 612 can be used to seal the opening 1121, preventing the receiving cavity 111 from being exposed to the outside, and further improving overall stability. By providing an opening 1121 on the first grip portion 11, the operating member 61 can have an operating end 612 located outside the receiving cavity 111, simplifying the overall structure. Furthermore, through reasonable design, the opening 1121 can be smaller; for example, the opening 1121 can match the operating end 612 so that the operating end 612 can seal the opening 1121, thus preventing the receiving cavity 111 from being exposed to the outside and further improving the stability of the overall structure. When pressure is applied, the operating end 612 moves into the receiving cavity 111 through the opening 1121. Thus, when the operating member 61 rotates, it drives the pushing member 62 to move. Since the moving parts are all within the receiving cavity 111, they are less susceptible to external environmental factors. Therefore, the overall transmission process, where pressure is applied to the operating member 61 to drive the pushing member 62 and further makes the locking component 63 switch between locked and unlocked states, is more stable.

[0030] Exemplarily, the first gripping part 11 may have a bottom housing 113 opposite to the opening 1121. A limiting sleeve 114 may be provided on the bottom housing 113. The pushing member 62 may pass through the limiting sleeve 114 so that it can be limited to being movable along the second direction YY when the operating member 61 rotates. The portion of the pushing member 62 extending along the second direction YY may pass through the limiting sleeve 114. In the embodiment shown in the figure, the pushing member 62 may be in the form of a rod extending along the second direction YY. The setting of the limiting sleeve 114 can further protect the pushing member 62, thereby making the structure of the pushing member 62 more stable and the overall structure more stable. Moreover, the limiting sleeve 114 can limit the movement of the pushing member 62 along the second direction YY, so that when the operating member 61 rotates to drive the pushing member 62 to move and further drives the locking component 63 to switch between the locked state and the unlocked state, it can be more stable.

[0031] For example, see Figure 7 , Figure 8 and Figure 9A connector 115 may be provided within the receiving cavity 111. The connector 115 may have a first end 1151 and a second end 1152. An operating member 61 may have a connecting portion 613 between the first rotating end 611 and the operating end 612. The first end 1151 and the connecting portion 613 may be rotatably connected via a first shaft 1153, and the second end 1152 may be rotatably connected to the limiting sleeve 114. The first shaft 1153 may be located at any suitable position. In the illustrated embodiment, the first shaft 1153 may be located on the connector 115. In embodiments not shown, the first shaft 1153 may also be located on the connecting portion 613. With the first rotating end 611 rotatably connected to the pusher 62, the first end 1151 of the connector 115 is rotatably connected to the connecting part 613, and the second end 1152 is rotatably connected to the limiting sleeve 114. The pusher 62 passes through the limiting sleeve 114. In this way, the part of the operating member 61 between the connecting part 613 and the first rotating end 611, the limiting sleeve 114, and the connector 115 can form a triangular structure. While driving the pusher 62 to move without affecting the rotation of the operating member 61, it can provide support for the operating member 61, thereby improving the stability of the overall structure.

[0032] For example, see Figure 3 , Figure 4 , Figure 5 and Figure 6 The operating end 612 can be connected to the bottom housing 113 via an elastic element 116. The elastic element 116 can be used to apply a restoring force acting in the first direction XX to the operating end 612. After the pressing force acting on the operating end 612 is released, under the restoring force of the elastic element 116, the operating end 612 can spring back to the outside of the receiving cavity 111. At the same time, the operating element 61 rotates, which can drive the pushing element 62 to move and further switch the locking component 63 between the locked state and the unlocked state. In this way, it is easier to switch the locking component 63 between the locked state and the unlocked state. The setting of the elastic element 116 can realize automatic reset, and the operation of the electrode clip 1 is also simpler.

[0033] For example, see Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 10A positioning sleeve 117 extending along the first direction XX can be provided on the bottom housing 113. The elastic element 116 can be sleeved on the positioning sleeve 117. A positioning post 6121 can be provided on the side of the operating end 612 facing the receiving cavity 111. The positioning post 6121 can be at least partially inserted into the positioning sleeve 117 and is movable relative to the positioning sleeve 117. On the one hand, the positioning sleeve 117 can provide support for the elastic element 116, preventing the elastic element 116 from undergoing deformation other than expansion and contraction during use, which would affect the rotation of the operating element 61. On the other hand, since the positioning sleeve 117 extends along the first direction XX, it can limit the movement of the positioning post 6121 in the direction perpendicular to the first direction XX, further improving the overall stability of the electrode clamp 1.

[0034] For example, see Figure 7 , Figure 8 , Figure 9 and Figure 10 The end of the pusher 62 furthest from the locking component 63 can be rotatably connected to the first rotating end 611 via a second shaft 621. The second shaft 621 can be positioned at any suitable location. In the illustrated embodiment, the second shaft 621 can be located on the pusher 62; in embodiments not shown, the second shaft 621 can also be located on the first rotating end 611. This rotatable connection between the end of the pusher 62 furthest from the locking component 63 and the first rotating end 611 via the second shaft 621 simplifies the movement of the pusher 62 by rotating the operating component 61, resulting in a simpler overall structure and easier implementation.

[0035] For example, see Figures 3-10The locking component 63 may have a locking member 631 and a locking mating member 632. The pushing member 62 and the locking member 631 can be rotatably connected via a third shaft 622. The second clamp 20 may have a second gripping portion 21 disposed opposite to the first gripping portion 11, and the locking mating member 632 may be disposed on the second gripping portion 21. The third shaft 622 may be disposed at any suitable position. In the illustrated embodiment, the third shaft 622 may be disposed on the pushing member 62; in an embodiment not shown, the third shaft 622 may also be disposed on the locking member 631. The locking mating member 632 may be disposed at any suitable position on the second gripping portion 21. When the pushing member 62 and the locking member 631 are rotatably connected via the third axis 622, the movement of the pushing member 62 along the second direction YY can drive the locking member 631 to rotate around the third axis 622. This allows the locking member 631 to rotate between an angle position where it engages with the locking mating member 632 and an angle position where it disengages from the locking mating member 632. In this way, the movement of the pushing member 62 switches the locking assembly 63 between the locked and unlocked states. The overall structure is simpler and easier to implement. Since the pushing member 62 can be located on the first gripping part 11, when the locking member 631 is rotatably connected to the pushing member 62 via the third axis 622, the locking mating member 632 is located on the second gripping part 21. When the locking member 631 and the locking mating member 632 engage to lock the locking assembly 63, the relative rotation between the first gripping part 11 and the second gripping part 21 can be restricted, which also restricts the relative rotation between the first clamp 10 and the second clamp 20. The locking member 631 and the locking mating member 632 can have any matching form, and the present invention does not limit them.

[0036] For example, see Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10The locking member 632 may have an arc-shaped body 6321 and a plurality of first teeth 6322 disposed on the arc-shaped body 6321. The locking member 631 may have a plurality of second teeth 6311 that mesh with the first teeth 6322. Exemplarily, the arc-shaped extension direction of the arc-shaped body 6321 may extend around the pivot 70. When the locking member 631 and the locking member 632 are engaged, the plurality of first teeth 6322 and the plurality of second teeth 6311 may engage. It is understood that the engagement referred to herein may be at least a portion of the first teeth 6322 engaging with at least a portion of the second teeth 6311, and the number of first teeth 6322 and second teeth 6311 engaging is not limited. When the locking member 631 and the locking mating member 632 are not engaged, that is, when the locking component 63 is in the unlocked state, the locking member 631 can rotate relative to the locking mating member 632 in a clockwise or counterclockwise direction. Since the first tooth 6322 and the second tooth 6311 are engaged, when the locking member 631 and the locking mating member 632 are engaged, the locking member 631 and the locking mating member 632 can only rotate relative to each other in one of the clockwise or counterclockwise directions, while the relative rotation in the other direction will be locked. In this way, when the locking component 63 is in the locked state, the first gripping part 11 and the second gripping part 21 can only rotate relative to each other in a direction that moves closer to each other or only in a direction that moves further away from each other. Thus, as long as the locking component 63 is kept in the locked state, automatic locking can be achieved. For example, through a reasonable structural design of the first tooth 6322 and the second tooth 6311, when the locking component 63 is in the locked state, the first gripping part 11 and the second gripping part 21 can only rotate relative to each other in a direction that moves closer to each other. Thus, as long as the locking component 63 is kept in the locked state, automatic locking can be achieved when the first gripping part 11 and the second gripping part 21 rotate relative to each other in a direction that moves closer to each other.

[0037] For example, see Figure 1 , Figure 2 , Figure 3 and Figure 4 When electrode clip 1 is used to measure ankle bones, it may further include a third clamp 30 and a fourth clamp 40. The third clamp 30 and the fourth clamp 40 together form a secondary clamp, which is located beside the first clamp 10 and the second clamp 20 along a third direction (ZZ direction shown in the diagram). The third clamp 30 can rotate synchronously with the first clamp 10, and the fourth clamp 40 can rotate synchronously with the second clamp 20. When measuring ankle bones, the ankle bones can be positioned between the first clamp 10 and the third clamp 30, and between the second clamp 20 and the fourth clamp 40. This allows for proper positioning of the measurement area; in other words, the secondary clamp formed by the third clamp 30 and the fourth clamp 40 provides auxiliary positioning, resulting in better measurement results.

[0038] For example, see Figure 1 , Figure 2 , Figure 3 and Figure 4 Taking the synchronous rotation of the first clamp 10 and the third clamp 30 as an example, the first clamp 10 and the third clamp 30 can be connected by an adjustment mechanism 80. The adjustment mechanism 80 can include an adjustment column 810 and an adjustment groove 820. One of the first clamp 10 and the third clamp 30 can be provided with an adjustment column 810, and the other can be provided with an adjustment groove 820. By inserting the adjustment column 810 into the adjustment groove 820, the first clamp 10 and the third clamp 30 can rotate synchronously. Such an electrode clamp 1 has a simpler overall structure and better overall stability.

[0039] For example, see Figure 1 , Figure 2 , Figure 3 and Figure 4 The adjusting groove 820 can be slightly larger than the adjusting column 810, allowing the adjusting column 810 to move within the adjusting groove 820. When the adjusting column 810 moves within the adjusting groove 820, the relative positions of the first clamp 10 and the third clamp 30 can be fine-tuned, thereby adjusting the relative clamping tightness of the first clamp 10 and the third clamp 30. Taking the measurement of the ankle bone as an example, the human segments located on both sides of the ankle bone usually have different sizes; for example, the ankle on one side of the ankle bone is usually thinner than the lower leg on the other side. In this case, fine-tuning the relative positions of the first clamp 10 and the third clamp 30 can prevent the third clamp 30 from clamping the lower leg too tightly when the first clamp 10 clamps the ankle. Such an electrode clamp 1 provides a better user experience.

[0040] It is understood that the above description of measuring the ankle bone with electrode clip 1 is only for illustrative purposes. The electrode clip 1 provided by this invention can also be applied to measure the styloid process of the ulna or any other human segment, similar to the above description, and will not be repeated here.

[0041] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front", "rear", "up", "down", "left", "right", "horizontal", "vertical", "horizontal", "top", and "bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms 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, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0042] For ease of description, relative terms such as "above," "over," "on the upper surface of," and "above" are used here to describe the regional positional relationship of one or more components or features shown in the figures to other components or features. It should be understood that relative terms include not only the orientation of the component as depicted in the figure but also different orientations during use or operation. For example, if the components in the figures are inverted as a whole, "above" or "above other components or features" will include cases where the component is "below" or "under" other components or features. Thus, the exemplary term "above" can include both "above" and "below." Furthermore, these components or features may also be positioned at other different angles (e.g., rotated 90 degrees or other angles), and this document intends to include all such cases.

[0043] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of features, steps, operations, parts, components, and / or combinations thereof.

[0044] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in sequences other than those illustrated or described herein.

[0045] The present invention has been described through the above embodiments. However, it should be understood that the above embodiments are for illustrative purposes only and are not intended to limit the invention to the scope of the described embodiments. Furthermore, those skilled in the art will understand that the present invention is not limited to the above embodiments, and many more variations and modifications can be made based on the teachings of the present invention, all of which fall within the scope of protection claimed by the present invention.
