Description

Electrode detection equipment, system and method for tumor electric field treatment

Technical Field

The invention relates to the technical field of medical equipment, in particular to electrode detection equipment, system and method for tumor electric field treatment.

Background

The tumor electric field treatment is an antimitotic noninvasive treatment method, and the application field is continuously expanded along with the development of science and technology. Tumor electric field therapy can deliver low-intensity, medium-frequency, alternating electric fields to the focal site, thereby destroying tumor cell division, inhibiting tumor cell proliferation, interfering with tumor cell migration and invasion, and reducing the ability of tumor DNA repair.

The electrode is an important component in the tumor electric field treatment equipment. At present, the electrodes are often configured to be an electrode patch to be attached to the body surface of the tumor part of the detected person, so that the electrodes can be used for implementing electric field treatment more tightly and durably. The electrodes comprise a flexible circuit board, a plurality of electrode plates arranged on the flexible circuit board at intervals and a plurality of temperature sensors arranged on the flexible circuit board and positioned at the same side of the electrode plates. The middle of each electrode plate is provided with a through hole. The plurality of temperature sensors are selectively accommodated in the through holes of the corresponding electrode sheets, namely, the temperature sensors are not accommodated in the through holes of the electrode sheets. The electrode plates and the flexible circuit board are electrically connected through welding. A gap is formed between the electrode plate and the flexible circuit board due to welding. Sealant is filled between the electrode plate and the flexible circuit board and in the through hole of the electrode plate. The sealant also coats the temperature sensor in the through hole of the corresponding electrode plate. The flexible circuit board of the electrode includes a soldering portion soldered to the lead. And a plurality of welding points welded with the lead are arranged on two sides of the welding part of the flexible circuit board. The electrodes transmit alternating voltage to each electrode pad welded to the flexible wiring board through the lead wires welded to the welding portion of the flexible wiring board, and then apply the alternating voltage to the tumor site of the subject through the electrode pads. Meanwhile, the electrodes transmit direct current voltage to the temperature sensor welded to the flexible circuit board through the lead welded to the welding part of the flexible circuit board, so that the temperature sensor senses the temperature of the skin at the corresponding position. Whether each electrode slice in the electrode is qualified or not has a great influence on the final treatment effect, and therefore, in order to ensure the treatment effect, the electrode slices need to be detected.

In the related art, before electrode detection, a metal plating layer needs to be provided on a surface of an electrode piece of an electrode on a side away from a flexible circuit board. During detection, the metal coating on the surface of the electrode plate of the electrode is pressed against a test board of the detection equipment through the pressing part of the detection equipment. Meanwhile, the test probes of the detection equipment are electrically contacted with a plurality of welding points of the welding part of the electrode to be detected so as to transmit direct current voltage to each temperature sensor and transmit alternating current voltage to each electrode plate of the electrode. The temperature sensors form an electric circuit by respective test probes electrically contacting a plurality of pads of the soldering portion of the electrode under test to sense the temperature of the environment in which the electrode under test is located. The temperature signal generated by the temperature sensor sensing the ambient temperature is collected by the detection equipment through the corresponding test probe. The metal coating on the surface of the electrode plate of the electrode is used as a conductive medium to couple each electrode plate of the tested electrode with the test board respectively, so that alternating electric fields are formed between each electrode plate of the tested electrode and the test board respectively. And then the detection equipment respectively detects and samples voltage signals between the electrode plates of the electrode to be detected and the test board. The metal coating on the surface of the electrode plate can also increase the capacitive reactance between the electrode plate and the test board, and amplify and detect the sampled voltage signal so as to judge whether each electrode plate of the tested electrode is qualified. After detection, the metal coating on the surface of each electrode plate of the electrode needs to be removed. This kind of detection mode, it is complicated to detect the process, and inefficiency.

In the related art, another detection method is to attach a metal sheet to the surface of an electrode sheet of a measured electrode so that each electrode sheet of the measured electrode is coupled with a test board, so as to form an alternating electric field between each electrode sheet of the measured electrode and the test board. The other detection mode avoids the complex operation of the previous detection mode and improves the efficiency. However, when the sealant filled between the electrode sheet and the flexible circuit board and in the through hole of the electrode sheet is too much, the sealant is likely to protrude from the through hole of the electrode sheet to the surface of the electrode sheet far away from the flexible circuit board. The height of the sealant bulge at the perforation of each electrode plate of the same electrode is different, and the electrode plates of the electrode are in rigid contact with the metal sheet, so that when the surface of the electrode plate of the electrode is attached to the surface of the metal sheet, the sealant bulges out of the height difference of the surface of the electrode plate, the distances between the electrode plates of the electrode and the test board are inconsistent, the electric field intensity of a plurality of alternating electric fields formed between the electrode plates of the electrode and the test board is inconsistent, and the data of the voltage signals for testing and sampling are inaccurate. Gaps between each electrode plate of the electrode and the corresponding metal sheet, which are generated due to the hard contact between the electrode plate and the corresponding metal sheet, are different, so that capacitive reactance between each electrode plate of the electrode and the test board is inconsistent, the amplification condition of voltage signals is inconsistent, and the judgment on whether each electrode plate of the electrode to be tested is qualified or not is easily influenced. In addition, because the metal sheet is in hard contact with the electrode plate of the electrode, under the action of pressing down of the pressing part of the detection equipment, the sealant protrudes out of the surface of the electrode plate, so that the electrode plate of the electrode cannot be in smooth contact with the metal sheet, and the electrode plate of the electrode is easy to damage due to uneven stress.

The test board 200 is a plate-shaped structure and is disposed on the base 100 in a flat assembly. The test board 200 is a circuit board for detecting a plurality of voltage signals between the electrode pads 710 of the electrode 700 to be tested and the test board 200, respectively. In this embodiment, the testing board 200 is provided with a plurality of independent electrode testing units 210 spaced from each other. The plurality of electrode test units 210 on the test board 200 are respectively in one-to-one correspondence with one electrode sheet 710 of the plurality of electrode sheets 710 of the at least one electrode 700 to be tested. The number of the electrode test units 210 is the same as the number of electrode pads 710 of the electrode 700 to be tested that need to be tested at one time. Taking fig. 1 as an example, one electrode under test 700 has 9 electrode pads 710, and if two electrodes under test 700 are simultaneously detected at one time, the number of the electrode test units 210 may be 18. The number of electrode test units 210 may be set according to the number of electrode pads 710 in each electrode 700 to be tested, and the number of electrodes 700 to be tested in the sacrificial portion 730.

As shown in fig. 6, a plurality of flexible conductors 300 are disposed on the upper surface of the test board 200 facing away from the base 100. The upper surfaces of the plurality of flexible conductors 300 are flush. The flexible conductor 300 is a conductive silicone sheet, and is a sheet structure made of conductive silicone, and the thickness of the flexible conductor can be 0.3-3 mm. The flexible conductor 300 has electrical conductivity and flexibility. The plurality of flexible conductors 300 respectively couple a corresponding one of the plurality of electrode pads 710 of the at least one electrode 700 to be tested with a corresponding one of the electrode test cells 210 of the test board 200.

Specifically, the upper surface of the test board 200 facing away from the base 100 is provided with a plurality of grooves 250. Each electrode test unit 210 is disposed in a corresponding one of the grooves 250. Each flexible conductor 300 is disposed over a corresponding electrode test unit 210. The flexible conductor 300 is partially located in the recess 250, and the flexible conductor 300 partially protrudes from the upper surface of the test board 200. During testing, the upper surface of the flexible conductor 300 protrudes from the upper surface of the test board 200, which is beneficial for the electrode pads 710 of the electrode 700 to be tested to abut against the corresponding flexible conductors 300.

The shape of the flexible conductor 300 may have a variety of arrangements, for example, the flexible conductor 300 may be round or square, etc. With continued reference to fig. 7, preferably, the center of each flexible conductor 300 is provided with a first through-hole 310 corresponding to a through-hole (not shown) in the center of the corresponding electrode pad 710 of the electrode 700 to be tested. The edge of each flexible conductor 300 is provided with a plurality of protrusions 320 arranged at intervals in the circumferential direction of the first through hole 310, and the plurality of protrusions 320 protrude in the radial direction of the first through hole 310.

The first through hole 310 of each flexible conductor 300 is a circular through hole, the axis of which may coincide with the axis of the flexible conductor 300, i.e. the first through hole 310 is arranged in the center of the flexible conductor 300. The first through hole 310 of each flexible conductor 300 is aligned with a through hole (not shown) in the center of the corresponding electrode sheet 710 of the test electrode 700, so that when the plurality of electrode sheets 710 of the electrode 700 to be tested are pressed against the corresponding flexible conductors 300 on the test board 200, the sealing glue (not shown) protruding from the surfaces of the corresponding electrode sheets 710 of the electrode 700 to be tested can be received, the electrode sheets 710 of the electrode 700 to be tested are further ensured to be at the same height, an alternating electric field with approximately consistent electric field intensity is formed between each electrode sheet 710 of the electrode 700 to be tested and the corresponding electrode test unit 210 of the test board 200, and the accuracy of the test result is further improved.

The plurality of protrusions 320 of the edge of each flexible conductor 300 may be arc-shaped protrusions or pointed-shaped protrusions. The plurality of protrusions 320 of the flexible conductor 300 may be disposed at intervals along the circumferential direction of the first through hole 310 thereof, so that the entire flexible conductor 300 may be substantially petaloid. The spacing between two adjacent protrusions 320 of the flexible conductor 300 facilitates weak deformation of the flexible conductor 300. That is, when the flexible conductors 300 disposed on the test board 200 are pressed by the movable assembly 400, the flexible conductors 300 can be more easily and completely attached to the corresponding electrode pads 710 of the electrode 700 to be tested.

In this embodiment, two lower probe pinholes 230 are disposed on the test board 200, so that two sets of lower probes 110 can upwardly penetrate through the test board 200 through the corresponding lower probe pinholes 230, so as to facilitate the contact between the lower probes 110 and the plurality of solder joints 721 on the lower surface of the corresponding electrode 700 to be tested. In addition, the upper surface of the test board 200 may further be provided with two pads 240 respectively corresponding to the welding portions 720 of the corresponding electrode 700 to be tested. Preferably, two spacers 240 are disposed adjacent to the lower probe pin holes 230, respectively. The two pads 240 respectively pad the welding portions 720 of the corresponding electrode 700 to be tested, so that each welding portion 720 can be kept substantially horizontal, and further, the contact reliability of the plurality of welding points 721 of each welding portion 720 with the corresponding group of lower probes 110 and the corresponding group of upper probes 420 is better.

Preferably, an electrode coupling plate 500 for fixing the test board 200 is disposed between the test board 200 and the base 100. That is, the test board 200 is assembled on the base 100 through the electrode coupling plate 500. In this embodiment, the testing board 200 is fixed on the upper surface of the electrode coupling board 500 away from the bottom board 120. For example, the test board 200 may be fixed to the electrode coupling board 500 by a conventional method such as screwing, clipping, bonding, etc. The electrode coupling plate 500 is also provided with two lower probe escape holes (not shown) through which the corresponding set of lower probes 110 pass.

The upper surface of the electrode coupling plate 500 is provided with a plurality of positioning portions 520 for engaging with the plurality of positioning holes 731 of the sacrificial portion 730 on the periphery of the electrode 700 to be tested one by one. The plurality of positioning parts 520 of the pole coupling plate 500 also penetrate the test plate 200. The positioning portions 520 are in a cylindrical structure, so that the positioning portions can be conveniently clamped into the corresponding positioning holes 731 of the sacrificial portions 730 on the periphery of the electrodes 700 to be tested, each flexible conductor 300 on the test board 200 is arranged over against one corresponding electrode sheet 710 of two electrodes 700 to be tested, and the test accuracy is improved.

First fastener escape holes 540 are respectively formed at positions of the electrode coupling plate 500 facing the plurality of first fasteners 123 for fixing the base plate 120 to the body 190. The plurality of first fastener escape holes 540 of the electrode coupling plate 500 may be used to receive the tops of the corresponding first fasteners 123, so that the electrode coupling plate 500 can be as close as possible to the bottom plate 120, or even fit seamlessly.

The electrode coupling plate 500 for supporting the test plate 200 is movably assembled on the base plate 120 of the base 100 up and down. When the movable assembly 400 is separated from the test board 200, the electrode coupling plate 500 supporting the test board 200 can be separated from the base 100 so that the top end of the lower probe 110 fixed on the base 100 moves to not protrude above the surface of the test board 200, thereby protecting the lower probe 110 and preventing the lower probe 110 from being damaged by the electrode 700 to be tested when the electrode 700 to be tested is placed on the test board 200.

In this embodiment, a plurality of first elastic members 121 are disposed between the bottom plate 120 and the electrode coupling plate 500, so that when the movable assembly 400 is separated from the test plate 200, the electrode coupling plate 500 is separated from the base 100 by the elastic force of the plurality of first elastic members 121. The plurality of first elastic members 121 are identical, so that the plurality of first elastic members 121 have the same elastic force. Specifically, the upper surface of the base plate 120 facing the electrode coupling plate 500 is provided with a plurality of annular grooves 122. The plurality of annular grooves 122 are identical in shape, and the plurality of annular grooves 122 are identical in size. One end of each first elastic member 121 abuts against a bottom wall (not numbered) of a corresponding one of the plurality of annular grooves 122, and the other end abuts against a lower surface of the electrode coupling plate 500. The annular groove 122 may function to receive the first elastic member 121. When the first elastic member 121 is compressed, most or all of it may be compressed into the annular groove 122, thereby further shortening the distance between the base plate 120 and the electrode coupling plate 500, so that the two may be nearly or completely attached, thereby improving the reliability of pressing the plurality of electrode pads 710 of the electrode 700 to be tested and the corresponding flexible conductors 300. Each annular groove 122 has a sidewall (not numbered) perpendicular to the test plate 200. The annular groove 122 can also guide the expansion and contraction of the first elastic member 121, so that the first elastic member 121 expands and contracts along the sidewall (not numbered) of the annular groove 122 in the vertical direction of the vertical test plate 200.

In this embodiment, one second hole 140 is disposed through each annular groove 122. A sliding rod 510 is disposed in each second hole 140. Each sliding bar 510 comprises a second section 512 and a first section 511 which are connected in sequence from top to bottom. The end of the second section 512 of each slide bar 510 facing away from the first section 511 is fixedly connected with the electrode coupling plate 500. An end of the second section 512 of each slide bar 510 facing away from the first section 511 may be provided with a threaded section (not shown), and the threaded section (not shown) may be screwed to the electrode coupling plate 500. Preferably, the top of each sliding bar 510 is embedded inside the electrode coupling plate 500. Each of the first elastic members 121 may be partially enclosed around a corresponding portion of the second section 512 of a corresponding one of the slide bars 510.

The base 100 is provided with a plurality of first holes 130 corresponding to the corresponding slide bars 510, respectively. The first section 511 of each slide bar 510 is received in a corresponding first hole 130 formed in the bottom plate 120 and can move up and down in the corresponding first hole 130.

Taking a plane parallel to the test board 200 as a cross section, the cross sectional area of the first section 511 of each slide bar 510 is the same, the cross sectional area of the second section 512 of each slide bar 510 is the same, the cross sectional area of each first hole 130 disposed on the base 100 is the same, and the cross sectional area of each second hole 140 disposed on the bottom plate 120 is the same. The cross-sectional area of the first section 511 of each slide bar 510 is greater than the cross-sectional area of the second section 512 thereof, the cross-sectional area of each first hole 130 provided on the base 100 is greater than the cross-sectional area of each second hole 140 provided on the bottom plate 120, and the cross-sectional area of the first section 511 of each slide bar 510 is greater than the cross-sectional area of each second hole 140 provided on the bottom plate 120.

The first section 511 of each slide bar 510 is the same length and the second section 512 of each slide bar 510 is the same length. Each of the second holes 140 provided on the base plate 120 has the same depth. The length of the second section 512 of each slide bar 510 is greater than the length of each second hole 140 provided on the base plate 120. When the electrode coupling plate 500 moves relative to the base plate 120, the second section 512 of each slide bar 510 can reciprocate in the corresponding second hole 140 provided on the base plate 120 following the electrode coupling plate 500. Since the cross-sectional area of the first section 511 of each slide bar 510 is greater than the cross-sectional area of each second hole 140 provided in the base plate 120, when each slide bar 510 is able to follow the upward movement of the electrode coupling plate 500 with respect to the base plate 120 under the action of the plurality of first elastic members 121, the first section 511 of each slide bar 510 does not move into the corresponding second hole 140, so that the electrode coupling plate 500 can be restricted from further moving upward, thereby maintaining the interval between the base plate 120 and the electrode coupling plate 500 within a fixed range.

In this embodiment, the electrode coupling plate 500 further has a plurality of first guide rods 530 extending in a direction perpendicular to the test plate 200. The plurality of first guide bars 530 are respectively located at four corners of the electrode coupling plate 500. The plurality of first guide bars 530 are spaced apart from the test board 200 on the electrode coupling plate 500. Each of the first guide bars 530 extends in a direction facing the base 100. The first sleeves 150 are respectively disposed on the base plate 120 at corresponding positions of the plurality of first guide bars 530 disposed corresponding to the electrode coupling plate 500. Each of the first guide bars 530 provided on the lower surface of the electrode coupling plate 500 can move up and down in the corresponding first sleeve 150 provided on the base plate 120. When the electrode coupling plate 500 is moved relative to the base plate 120, each of the first guide bars 530 may be moved in a direction perpendicular to the test plate 200 along the corresponding first sleeve 150. The guide function of the first guide bar 530 and the first sleeve 150 may make the movement of the electrode coupling plate 500 more smooth.

The length of each first sleeve 150 in the direction perpendicular to the test plate 200 may be equal to or greater than the thickness of the base plate 120. The upper surface of each of the first sleeves 150 may be flush with the upper surface of the base plate 120 so as not to affect the relative movement between the base plate 120 and the electrode coupling plate 500. The lower end surface of each first sleeve 150 may be flush with the lower surface of the base plate 120, or the lower end of each first sleeve 150 may protrude from the lower surface of the base plate 120. In this embodiment, the length of each first sleeve 150 is greater than the thickness of the base plate 120. That is, each of the first sleeves 150 protrudes downward from the lower surface of the base plate 120. The base 100 is provided with a plurality of first sleeve escape holes 151 corresponding to the respective first sleeves 150 one-to-one. A portion of the first sleeve 150 protruding out of the lower surface of the base plate 120 may protrude into the first sleeve escape hole 151. Preferably, the length of each first guide bar 530 may be greater than the total thickness of the electrode coupling plate 500, the bottom plate 120 and the upper plate 191 of the base 100.

The moving assembly 400 has a pressing portion 410 for pressing the plurality of electrode pads 710 of the electrode 700 to be tested against the corresponding flexible conductors 300 on the test board 200. The structure of the press-fit portion 410 may be various. For example, the pressing portion 410 may have a horizontally disposed pressing surface (not shown), which may simultaneously press the electrode pads 710 of the electrode 700 to be tested against the corresponding flexible conductors 300 on the test board 200. The moving assembly 400 moves along a direction perpendicular to the test board 200, and can drive the pressing portion 410 to move, so that the pressing portion 410 contacts a corresponding portion of the electrode 700 to be tested, and the pressing portion 410 provides pressure to press the electrode pads 710 of the electrode 700 to be tested against the corresponding flexible conductors 300.

Referring to fig. 6, in the present embodiment, the moving assembly 400 further includes a pressing plate 440 and a top plate 430, which are sequentially disposed along a direction away from the base 100. The pressing plate 440 is fixedly disposed under the top plate 430. In this embodiment, the surface of the pressure plate 440 facing the top plate 430 is provided with a plurality of mounting posts 442. One second fastener 443 is provided for each mounting post 442. Each second fastener 443 may be inserted through the top plate 430 and fixed to a corresponding mounting post 442 of the pressure plate 440, thereby fixing the pressure plate 440 below the top plate 430, and there may be a certain space between the pressure plate 440 and the top plate 430. A plurality of mounting posts 442 may be disposed around the pressure plate 440 to improve connection reliability.

The press 410 may include a plurality of identical press bars 411 movably connected to the top plate 430. The plurality of pressing rods 411 are respectively arranged in one-to-one correspondence with the corresponding flexible conductors 300 on the test board 200. Each strut 411 passes through the top plate 430 and the pressure plate 440. The pressing plate 440 is provided with a plurality of second through holes 441. The bottom of each pressing rod 411 movably penetrates through the corresponding second through hole 441. The diameter of the second through hole 441 may be slightly larger than that of the pressing rod 411, so that the pressing rod 411 may move within the second through hole 441 of the pressing plate 440 relative to the pressing plate 440. The second plurality of through holes 441 of the pressure plate 440 may serve as a guide. The bottoms of the pressing rods 411 are respectively contacted with corresponding parts of the electrode 700 to be detected through corresponding second through holes 441 on the pressing plate 440, so that the phenomenon that the pressing rods 411 are inclined to cause uneven stress on the electrode pieces 710 of the electrode 700 to be detected and influence on detection accuracy is avoided.

Specifically, each of the pressing rods 411 includes a rod 412 extending in a direction perpendicular to the test board 200, and a head 413 connected to the rod 412 and adapted to contact a corresponding portion of the electrode 700 to be tested. The rod 412 of each pressing rod 411 is a rod-shaped structure. The head 413 of each pressing rod 411 is the bottom of the pressing rod 411, and may be a block-shaped structure, and the lower surface of the pressing rod is a plane, so as to press the corresponding electrode sheet 710 of the electrode 700 to be tested against the corresponding flexible conductor 300. The head 413 of each pressing rod 411 is movably arranged through the corresponding second through hole 441.

The rod 412 of each strut 411 includes a middle section 412a, and a first protrusion 412b and a second protrusion 412c respectively located at two ends of the middle section 412 a. The rod body 412 of each pressing rod 411 includes, in order from top to bottom, a first protrusion 412b, an intermediate section 412a, and a second protrusion 412 c. The second protrusion 412c and the middle section 412a of each pressing rod 411 are inclined from a step surface 412 d. The second protrusion 412c of each plunger 411 is connected to its head 413. For example, the head 413 of each plunger 411 may be attached to its second protrusion 412c by a screw (not numbered). Specifically, a countersunk hole (not numbered) may be disposed on the head 413 of each pressing rod 411, so that a screw (not numbered) does not protrude from the lower surface thereof, and the screw does not affect the contact with the corresponding portion of the electrode 700 to be tested.

Correspondingly, a plurality of identical second sleeves 431 (shown in fig. 6) corresponding to the plurality of pressing rods 411 in a one-to-one manner are arranged on the top plate 430. Each second sleeve 431 is longitudinally fixed to the top plate 430. Each of the second sleeves 431 may have a length greater than the thickness of the top plate 430, a top end protruding upward from the upper surface of the top plate 430, and a bottom end protruding downward from the lower surface of the top plate 430.

Each of the second sleeves 431 provided on the top plate 430 has a side wall 431a and a top wall 431b connected to the side wall 431 a. The top wall 431b of each second sleeve 431 is provided with a third through hole 431c for penetrating the middle section 412a of the corresponding pressure rod 411.

The first protrusion 412b of each strut 411 is located outside the top wall 431b of the corresponding second sleeve 431 and has a cross-sectional area larger than that of the corresponding third through hole 431c, so that each strut 411 is movably connected to the corresponding second sleeve 431 to prevent each strut 411 from being separated from the corresponding second sleeve 431 under the action of gravity.

A second elastic member 460 is disposed between the top plate 430 and each pressing rod 411. Each second elastic member 460 is used to provide an elastic force for the corresponding pressure rod 411 to press the corresponding electrode pad 710 of the electrode 700 to be tested against the corresponding flexible conductor 300. The second elastic member 460 may also be an elastic block, an elastic sleeve, a coil spring, or the like. In this embodiment, each of the second elastic members 460 is a coil spring, and is located between the side wall 431a of the corresponding second sleeve 431 of the top plate 430 and the middle section 412a of the corresponding pressing rod 411. That is, each of the second elastic members 460 is located in the corresponding second sleeve 431 and sleeved outside the middle section 412a of the corresponding compression bar 411. Both ends of each second elastic member 460 respectively abut against the top wall 431b of the corresponding second sleeve 431 and the second protrusion 412c of the corresponding pressing rod 411 and protrude out of the step surface 412d of the middle section 412 a. The diameter of the second protrusion 412c of each strut 411 may be slightly smaller than the inner diameter of the sidewall 431a of the corresponding second sleeve 431 such that the intermediate section 412a and the second protrusion 412c of each strut 411 are both movable within the corresponding second sleeve 431.

Each set of upper probes 420 is disposed on the top plate 430 of the moving assembly 400. In this embodiment, one upper probe base 480 is provided on the top plate 430 for each set of upper probes 420. Each upper probe base 480 is fixed to the top plate 430. Each set of upper probes 420 is inserted through and fixed to a corresponding one of the upper probe bases 480. Each set of upper probes 420 is secured to the top plate 430 by a respective upper probe mount 480. The pressure plate 440 has upper probe avoiding holes (not shown) at positions corresponding to each set of upper probes 420 for the corresponding set of upper probes 420 to pass through, so that the corresponding set of upper probes 420 can be conveniently contacted with the plurality of welding points 721 on the upper surface of the corresponding electrode 700 to be tested.

The pressing plate 440 is further provided with a plurality of positioning portion avoiding holes 444 respectively facing the corresponding positioning portions 520 of the electrode coupling plate 500, so that the plurality of electrode sheets 710 of the electrode 700 to be tested can be tightly pressed against the corresponding flexible conductors 300.

The base 100 also includes a bracket 160 disposed on its body 190. The bracket 160 is located at the rear side of the body 190 and may be fixed to the body 190 by means of screws or the like. The support 160 is connected by a plurality of vertical plates, and extends in a direction perpendicular to the test board 200 as a whole.

The electrode-detecting apparatus 1000 for electric-field treatment of tumors further comprises a handle assembly 600 coupled to the bracket 160 of the base 100. The frame 160 is substantially 7-shaped when viewed from the side, such that the moving member 400, the electrode coupling plate 500, the test plate 200, and the bottom plate portion are positioned below the frame, and the handle member 600 is positioned above the moving member 400. The handle assembly 600 is also connected with the moving assembly 400 for drawing the moving assembly 400 to move in a direction perpendicular to the test plate 200. In this embodiment, referring to fig. 3, the moving assembly 400 further includes an arched bracket 470 disposed on a side of the top plate 430 facing away from the base 100. The arched bracket 470 may have an arched shape, and a driving rod installation hole 471 is formed on the arched bracket. The handle assembly 600 includes a handle 610 hinged to the bracket 160, a transmission rod 620 connected to the handle 610, and a sleeve 630 guiding the transmission rod up and down. The end of the drive link 620 facing away from the handle 610 is attached to the arcuate bracket 470. Specifically, the end of drive rod 620 facing away from handle 610 is mounted in drive rod mounting hole 471. The driving rod 620 may be fixedly coupled to the driving rod installation hole 471, or the driving rod 620 may move up and down within the driving rod installation hole 471 to a small extent. In this embodiment, the moving assembly 400 is moved by manual force through the handle assembly 600. In other embodiments, a motor (not shown) capable of outputting linear motion may be connected to the moving assembly 400, so that the motor (not shown) can perform the motion along the linear direction.

The handle 610 is able to rotate relative to the bracket 160. The handle 610 and the transmission rod 620 can be connected to the transmission rod 620 through a rack-and-pinion or a link mechanism, so that the rotation of the handle 610 can be changed into the movement of the transmission rod 620 along the direction perpendicular to the test board 200, so as to move the moving assembly 400 fixed by the transmission rod 620 along the direction perpendicular to the test board 200.

The driving force of the operator rotating the handle 610 may be transmitted to the moving assembly 400 through the driving rod 620. The driving rod installation hole 471 of the arched bracket 470 of the movable assembly 400 can correspond to the center of the test board 200, so that the movement of the movable assembly 400 is more smooth, and the force of the movable assembly 400 pressing the electrode 700 to be tested is more uniform.

In addition, in order to further improve the stability of the movement of the moving assembly 400, a plurality of third guide rods 170 (shown in fig. 2) extending in a direction perpendicular to the test board 200 are disposed on the base 100, and a plurality of third sleeves 450 (shown in fig. 6) are disposed on the top plate 430. Each third guide bar 170 is slidably disposed within a corresponding third sleeve 450. Preferably, at least one of the plurality of third guide rods 170 is further connected to the bracket 160.

Specifically, the plurality of third guide rods 170 are all fixed on the upper panel 191 of the body 190 of the base 100. At least one of the plurality of third guide rods 170 sequentially penetrates through the second mounting hole 171 correspondingly disposed on the bottom plate 120 and the third mounting hole 172 correspondingly disposed on the electrode coupling plate 500, and then extends into the corresponding third sleeve 450 on the top plate 430. The third sleeves 450 disposed on the top plate 430 are respectively located around the top plate 430 and at the periphery of the pressing plate 440. A plurality of third guide rods 170 are coupled around the top plate 430 by corresponding third sleeves 450 on the top plate 430. The pressing plate 440 is located in an area surrounded by the plurality of third guide rods 170.

If the deviation is within a preset range, for example, within a range of 4-5V, the electrode sheet 710 is determined to be qualified, and if the deviation exceeds too much, the electrode sheet is determined to be unqualified. Where k is the dielectric constant, b is the zero compensation parameter, x is the sampling value, i.e., the acquired voltage value, and y is the actual voltage, i.e., the actual value of the function derivation.
