Description

Technical Field

[0001] The embodiments of the present disclosure relate to the field of electrode technology, and in particular to a directional electrode and an implantable stimulation system. Background Art

[0002] Deep brain stimulation (DBS) is an invasive neuromodulation technology that uses stereotactic surgery to implant stimulating electrodes into specific neural structures in the human brain, and implants a neurostimulator in the human body to connect the electrodes, emitting weak electrical pulses that can be adjusted and controlled, thereby changing the electrical activity and function of the brain's neural circuits and networks, and achieving the purpose of controlling and improving user symptoms.

[0003] The stimulation output metal contacts of traditional DBS electrodes are arranged in a circular ring on the main body of the wire. The entire electrode is rotationally symmetrical at any angle and has no specific orientation. However, this structure can only form an approximately spherical electric field, which may stimulate unexpected tissues or structures and produce certain side effects. The current new DBS electrode design allows the original circular stimulation output metal contacts to be split into multiple pieces, usually into three equal pieces. This can achieve directional stimulation, form a stimulation field with a specific direction, and accurately release electrical stimulation to a specific area, while also achieving efficient energy utilization. The new DBS electrode even allows the design of some special-shaped contacts. Therefore, the new DBS electrode currently supports independent regulation of the stimulation output parameters of one or more pieces, thereby achieving stimulation of brain tissue in a specific direction. Therefore, the new DBS electrode can be called a directional electrode.

[0004] However, the structure of the currently used directional electrodes is difficult to meet the needs of directional electrode orientation recognition, which needs to be solved urgently. Summary of the invention

[0048] In order to enable those skilled in the art to better understand the disclosed solution, the technical solution in the disclosed embodiment will be clearly and completely described below in conjunction with the drawings in the disclosed embodiment. Obviously, the described embodiment is only a part of the disclosed embodiment, not all of the embodiments. Based on the embodiments in the disclosed embodiment, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the disclosed embodiment.

[0049] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The situations of "target", "original", etc. are similar and will not be repeated here. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products, or devices.

[0050] Before introducing the embodiments of the present disclosure, the application scenarios of current directional electrodes, the current directional electrode schemes and the reasons why the problem of being difficult to meet the needs of directional electrode orientation identification are first exemplified, so as to better understand why the directional electrode scheme proposed in the embodiments of the present disclosure can realize the orientation identification of the directional electrode.

[0051] Exemplarily, implantable medical systems include implantable neural stimulation systems, implantable cardiac stimulation systems (also known as pacemakers), implantable drug delivery systems (IDDS), and lead switching systems. Examples of implantable neural stimulation systems include deep brain stimulation systems (DBS), implantable cortical nerve stimulation systems (CNS), implantable spinal cord stimulation systems (SCS), implantable sacral nerve stimulation systems (SNS), and implantable vagus nerve stimulation systems (VNS). An implantable neural stimulation system includes a stimulator implanted in a user's body (i.e., an implantable neural stimulator) and a programmable device disposed outside the user's body. In other words, the stimulator is a medical device, or in other words, the medical device includes a stimulator. The relevant neuromodulation technology mainly involves implanting directional electrodes (the directional electrodes are in the form of a wire body, for example) in specific locations (i.e., target sites) of biological tissues through stereotactic surgery, and sending discharge pulses to the target sites through the electrodes to regulate the electrical activities and functions of the corresponding neural structures and networks.

[0052] DBS can include an IPG (Implantable Pulse Generator), an extension wire and a wire body. The IPG is connected to the wire body through the extension wire. The IPG can be implanted in the user's body, for example, in the tinned chest or other body parts; DBS can also include an IPG and a wire body. The IPG is directly connected to the wire body. The IPG is implanted in the user's head, for example, a groove is made in the user's skull, and then the IPG is installed in the groove of the skull. In this case, the IPG may not protrude from the outer surface of the skull, or may partially protrude from the outer surface of the skull. Among them, the IPG responds to the program-controlled instructions sent by the program-controlled device, relies on sealed batteries and circuits to provide controllable electrical stimulation therapy (or electrical stimulation energy) to the body tissue. The IPG delivers one or more controllable specific electrical stimulations to specific areas of the body tissue through the wire body; the extension wire is used in conjunction with the IPG as a transmission medium for electrical stimulation, and transmits the electrical stimulation generated by the IPG to the wire body.

[0053] The electrical stimulation can be delivered in the form of a pulse signal or a non-pulse signal. For example, the electrical stimulation can be delivered as a signal with various waveform shapes, frequencies and amplitudes. Therefore, the electrical stimulation in the form of a non-pulse signal can be a continuous signal, which can have a sine waveform or other continuous waveform. After receiving the electrical stimulation transmitted by the IPG or the extension wire, the lead body delivers the electrical stimulation to a specific area of ​​the tissue in the body through a plurality of electrode contacts. The stimulator is provided with, for example, one or more lead bodies on one side or both sides, and a plurality of electrode contacts are provided on the lead body. The electrode contacts can be arranged uniformly or non-uniformly on the circumference of the lead body. The electrode contacts can be arranged in an array of 4 rows and 3 columns (a total of 12 electrode contacts) on the circumference of the lead body. The electrode contacts can include stimulation electrode contacts and / or collection electrode contacts. The electrode contacts can be in the shape of sheets, rings or dots, for example.

[0054] The stimulated body tissue may be the user's brain tissue, and the stimulated site may be a specific site of the brain tissue. The stimulated sites of different users are generally different, and the number of stimulation contacts (single source or multiple sources), the use of one or more (single channel or multiple channels) of specific electrical stimulation, and the stimulation parameters (values) are also different. The user tissue type for which the stimulation is applicable is not limited, and it may be a disease type applicable to deep brain stimulation (DBS), spinal cord stimulation (SCS), sacral nerve stimulation, gastric stimulation, peripheral nerve stimulation, and functional electrical stimulation.

[0055] When the program-controlled device and the stimulator establish a program-controlled connection, the program-controlled device can be used to adjust one or more stimulation parameters of the stimulator (or one or more stimulation parameters of the pulse generator, and different stimulation parameters correspond to different electrical stimulations), or the stimulator can sense the user's electrophysiological activities to collect electrophysiological signals, and the stimulation parameters of the stimulator can be adjusted through the collected electrophysiological signals to achieve closed-loop control (or adaptive adjustment) of the stimulation parameters. The stimulation parameters may include at least one of the following: electrode contact identifiers for delivering electrical stimulation (for example, electrode contacts 2# and electrode contacts 3#), frequency (for example, the number of electrical stimulation pulse signals per unit time 1s, in units of Hz), pulse width (duration of each pulse, in units of μs), amplitude (generally expressed in voltage, i.e., the intensity of each pulse, in units of V), timing (for example, continuous or burst, and burst refers to a discontinuous timing behavior composed of multiple processes), stimulation mode (including one or more of current mode, voltage mode, timed stimulation mode, and cyclic stimulation mode), doctor-controlled upper and lower limits (ranges that can be adjusted by doctors), and user-controlled upper and lower limits (ranges that can be adjusted by users themselves). The stimulation parameters of the stimulator can be adjusted in current mode or voltage mode. The program-controlled device may include a doctor program-controlled device (i.e., a program-controlled device used by a doctor) and / or a user program-controlled device (i.e., a program-controlled device used by a user). The doctor program-controlled device is, for example, a tablet computer, a laptop computer, a desktop computer, a mobile phone or other intelligent terminal device equipped with program-controlled software. The user program-controlled device is, for example, a tablet computer, a laptop computer, a desktop computer, a mobile phone or other intelligent terminal device equipped with program-controlled software. The user program-controlled device may also be other electronic devices with program-controlled functions (e.g., a charger with program-controlled functions, an electrophysiological acquisition device, etc.).

[0056] After the current directional electrodes are implanted in the human body, the feasible solutions for determining their orientation are all based on cranial X-ray films, that is, by comparing the cranial X-ray films with pre-taken or drawn standard pictures to obtain electrode orientation information. However, this solution has the following disadvantages: it relies on doctors to manually compare cranial X-ray films with standard pictures, and cannot perform automatic recognition; the angle difference between two adjacent angle standard pictures determines the minimum accuracy of the directional electrode angle that can be determined by the solution. The current mainstream solution is to divide 360° into 8 pictures, and the minimum resolution angle is 45°; cranial X-ray films can only clearly develop bony structures such as the skull, and cannot display soft tissues or liquid decomposition such as brain tissue and ventricles, so it is impossible to identify the specific position of the directional electrode relative to the brain nuclei; not all human users will collect cranial X-ray films after implanting directional electrodes. A more common method is to collect computed tomography (CT) images after implanting directional electrodes.

[0057] However, the current method of determining the orientation of the directional electrode by the development characteristics of the directional electrode in the CT images collected after the directional electrode is implanted has the following defects: the most popular directional electrode with three-equally divided contacts, although the contact design and the design of the direction mark have a certain degree of mechanical structure asymmetry, these asymmetric structures are presented in the CT scan, and the artifact characteristics cannot accurately indicate the electrode orientation, that is, for example, see Figure 1 The cross-sectional structure of the metal contacts, and Figure 2 The image obtained by simulating the CT image of the metal contact is shown in Figure 1. The artifact of the metal contact development divided into three equal parts is six rays of light and dark alternating at equal angles. Each bright line corresponds to the center of the metal contact or the gap between two metal contacts. This is because the line connecting the two ends of the same metal contact produces a dark line, and each gap produces two dark lines, which are emitted from the edges of two adjacent metal contacts respectively. See Figure 3 The current medical CT images of directional electrodes taken under conventional cranial brain scanning parameters are not able to identify the details of the locations where the two dark lines are emitted due to the current mainstream medical CT resolution. Therefore, it is impossible to know whether the bright area between the two dark lines corresponds to a metal contact or a gap. In other words, of the two adjacent bright areas, one corresponds to a contact and the other corresponds to a gap, but which one corresponds to the contact cannot be known from the CT image.

[0058] In summary, there are various shortcomings in identifying the direction of directional electrodes using cranial X-ray films, and the imaging characteristics of the mechanical structure of the direction marker of the directional electrode in CT images are currently difficult to meet the needs of directional electrode direction identification.

[0059] In view of this, the embodiment of the present disclosure sets an arc-shaped direction mark including a first notch on the directional electrode, so that an artifact corresponding to the direction mark and capable of indicating the direction of the directional electrode can be seen in the medical image, thereby realizing the direction identification of the directional electrode through the artifact. This will be explained in detail below.

[0060] Figure 4 1 is a structural block diagram of a directional electrode provided by an embodiment of the present disclosure. This embodiment is applicable to the situation of directional electrode orientation recognition.

[0061] See also Figure 4 , the directional electrode of the embodiment of the present disclosure comprises:

[0062] A wire body 110, on which at least one set of directional electrode contacts 130 is disposed;

[0063] Direction marker 120, which is arranged on the wire body 110 in an arc shape, includes a first marker arc 121 and a second marker arc 122, and a first gap 123 is provided between the first marker arc 121 and the second marker arc 122. The wire body 110 is the main body of the wire used to set the directional electrode contact 130 and the direction marker. The electrode contact is a contact that can perform electrical stimulation or data acquisition. The direction marker 120 is a marker used to determine the orientation of the directional electrode through medical images. Specifically, the direction marker 120 can make the artifact corresponding to the direction marker 120 visible in the medical image, thereby realizing the orientation identification of the directional electrode through the artifact; the material of the direction marker 120 can be metal material, or other materials that can present corresponding artifacts in medical images. The first marker arc 121 is an arc that constitutes the direction marker 120. The second marker arc 122 is another arc that constitutes the direction marker 120. The first notch 123 is a notch between the first identification arc 121 and the second identification arc 122; the first notch 123 can be located in the center of the direction mark 120 or on one side, that is, the angle ranges corresponding to the first identification arc 121 and the second identification arc 122 can be the same or different. In the present disclosed embodiment, the position of the first notch 123 in the direction mark 120 is not specifically limited.

[0064] In the embodiment of the present disclosure, the direction mark 120 may be a mark additionally provided on the wire body 110 , or the directional electrode contact 130 may be used as the direction mark 120 .

[0065] Optionally, the arc shape angle range corresponding to the direction mark is [145°, 270°]; and / or, the notch arc angle range corresponding to the first notch is [30°, 90°].

[0066] The arc shape angle range is the angle range of the arc corresponding to the direction mark 120, which can be understood as the arc range between the two distal ends of the first mark arc 121 and the second mark arc 122. The notch arc angle is the angle range of the arc corresponding to the notch, that is, the distance angle between the first mark arc 121 and the second mark arc 122. Generally, in the circumferential direction, there are two notches between the first mark arc 121 and the second mark arc 122, and a notch not exceeding 90° can be determined as the first notch 123.

[0067] In one embodiment of the present disclosure, when the arc shape angle range is [145°, 270°], and / or the notch arc angle range is [30°, 90°], that is, when the arc angle of the overall arc corresponding to the direction mark 120 is less than or equal to 270 degrees and greater than or equal to 145 degrees, and / or the arc angle of the arc corresponding to the first notch 123 is less than or equal to 90 degrees and greater than or equal to 30 degrees, the best pointing effect of the orientation of the directional electrode can be obtained. Optionally, the arc shape angle and the first notch 123 can have the following combination: [180°~240°, 30°~60°].

[0068] It can be understood that, since the positional relationship between the direction marker 120 and the directional electrode contact 130 is fixed, the direction marker 120 with the above-mentioned structural design can obtain better images with identification capabilities under CT images. In this way, when the direction of the direction marker 120 is determined, the direction of the directional electrode contact 130 can be quickly determined, thereby determining the specific position of the directional electrode contact 130 with different directions in the implantation area (such as the user's brain nucleus), which is convenient for doctors to perform targeted input electrical stimulation according to the actual state of the user. For example, see Figure 5 The direction mark 120 with an arc shape angle of 180° includes a first mark arc 121 and a second mark arc 122 , and a first notch 123 with a notch arc angle of 45° is provided between the first mark arc 121 and the second mark arc 122 .

[0069] For example, see Figure 6 The direction mark 120 with an arc shape angle of 180° includes a first mark arc 121 and a second mark arc 122, and a first notch 123 with a notch arc angle of 60° is provided between the first mark arc 121 and the second mark arc 122; Figure 6 It can be seen that the direction mark 120 can present a metal artifact with a directional effect under the CT image, that is, in the CT image, a dark line is generated in the direction of the area corresponding to the first notch 123, and another two dark lines are generated in the areas corresponding to the first mark arc 121 and the second mark arc 122. The three dark lines together constitute a specific "⊥"-shaped dark line mark with direction indication capability.

[0070] Optionally, the direction marker 120 also includes a connecting portion, wherein the connecting portion is used to connect the first marker arc and the second marker arc; the number of connecting portions may be at least one, for example, the number of connecting portions may be two, to respectively connect the two ends of the first marker arc 121 and the second marker arc 122.

[0071] In the embodiments of the present disclosure, see Figure 7The direction indicator 120 may further include a connecting portion connecting the first indicator arc 121 and the second indicator arc 122 , so that the direction indicator 120 is integrally formed through the connecting portion, thereby facilitating the manufacture and assembly of the direction indicator 120 .

[0072] Furthermore, the material of the connecting part can be a non-metallic material, such as a rubber material or a plastic material, so that the non-metallic connecting part will not affect the imaging during CT image acquisition, thereby avoiding the material of the connecting part affecting the imaging and identification effect of the direction mark 120 during CT image acquisition, and also avoiding the metal connecting part from producing a stochastic effect when the directional electrode contact 130 delivers electrical stimulation, thereby causing an uncomfortable experience for the user.

[0073] In the embodiment of the present disclosure, there is no specific limitation on the position of the connecting portion; for example, the connecting portion and the first notch 123 may be located at the same position in a direction parallel to the wire body 110 and at a different position in a direction perpendicular to the wire body 120; for another example, the connecting portion and the first notch 123 may be located at a different position in a direction parallel to the wire body 120.

[0074] Optionally, the curvature of the first identification arc is equal to the curvature of the second identification arc. It can be understood that setting the first notch 123 in the middle position of the two identification arcs can achieve a relatively symmetrical imaging effect, which can improve the recognition accuracy of the direction marker 120 under CT imaging conditions to a certain extent, thereby improving the accuracy of the orientation recognition of the directional electrode.

[0075] Optionally, in the image captured for the directional electrode, the area corresponding to the direction mark has at most one symmetry axis to avoid the situation where the direction of the directional electrode cannot be identified due to the presence of multiple symmetry axes. The image is an image captured for the directional electrode; the captured image can be captured by medical imaging.

[0076] Optionally, the image is a computed tomography (CT) scan image, and the acquisition direction of the image is the direction of the length of the wire body perpendicular to the image, so that the orientation of the directional electrode can be easily identified using the image, avoiding the occurrence of orientation identification errors caused by deviations in the image acquisition angle. Optionally, the length direction of the perpendicular wire body 110 in the acquisition direction can be understood as approximately vertical or close to vertical, because there may be certain deviations in actual operation.

[0077] It can be understood that, taking DBS as an example, the electrodes are generally implanted in the user's brain at an inclined angle. When taking CT images, the user's head is generally used as the basis for acquisition, for example, the acquisition is performed from the user's lower jaw to the top of the skull. During acquisition, the direction of the directional electrode is actually a non-vertical direction. Therefore, the direction marker 120 is required to have a stronger identification effect when the directional electrode is approximately vertical or close to vertical (for example, between 80° and 100°). Therefore, the positional relationship and angle relationship between the first identification arc 121 and the second identification arc 122 in the direction marker 120 need to have a better identification effect when the directional electrode is approximately vertical or close to vertical, so as to achieve targeted direction recognition.

[0078] Optionally, the distance between the directional electrode contact and the directional marker is in the range of [2 mm, 12 mm].

[0079] In the embodiment of the present disclosure, the direction marker 120 can be located above the directional electrode contact 130 at the implanted end of the wire body 110. If the distance between the directional electrode contact 130 and the direction marker 120 is too short, the artifacts corresponding to the directional electrode contact 130 and the direction marker 120 may interfere with each other. If the distance between the directional electrode contact 130 and the direction marker 120 is too long, it may cause the problem that the accuracy of the direction identification of the directional electrode is reduced due to the twisting of the wire body 110. Therefore, the distance between the directional electrode contact 130 and the direction marker 120 can range from [2 mm, 12 mm], that is, the distance between the directional electrode contact 130 and the direction marker 120 is less than or equal to 12 mm and greater than or equal to 2 mm, so as to obtain the best pointing effect of the direction of the directional electrode. Optionally, the distance between the directional electrode contact and the direction marker 120 can be, for example, 3 mm, 4 mm, 6 mm or 8 mm, etc. The specific value of the distance can be determined by factors such as the electrode spacing in the directional electrode and / or the implantation environment, and is not limited in the embodiment of the present disclosure.

[0080] In some other embodiments, the direction indicator 120 further includes at least one third indicator arc, and at least one second gap is provided between the at least one third indicator arc and the first indicator arc and / or the second indicator arc.

[0081] The third identification arc is another arc constituting the direction identification 120. The second notch is a notch on the direction identification 120; the second notch may be located in the middle of the direction identification 120 or may be biased to one side, that is, the angle ranges corresponding to the first identification arc 121, the second identification arc 122 and the third identification arc may be the same or different. In the embodiment of the present disclosure, the position of the second notch in the direction identification 120 is not specifically limited.

[0082] In the embodiment of the present disclosure, the direction marker 120 also includes at least one second notch, so as to divide the arc-shaped direction marker 120 as a state into a first marker arc 121, a second marker arc 122 and at least one third marker arc through the first notch 123 and the second notch, thereby improving the accuracy of the direction recognition of the directional electrode.

[0083] Optionally, the thicknesses of the first identification arc and the second identification arc are different, and / or the lengths of the first identification arc and the second identification arc are different.

[0084] In the embodiment of the present disclosure, the first identification arc 121, the second identification arc 122 and / or at least one third identification arc can be globally or locally thickened or thinned, and the arc lengths of the first identification arc 121, the second identification arc 122 and / or at least one third identification arc can be different, thereby improving the accuracy of orientation identification of the directional electrode.

[0085] In the embodiment of the present disclosure, the direction mark 120 may also be an arc-shaped mark without a gap, that is, the direction mark 120 may also include only the first mark arc 121 or the second mark arc 122 .

[0086] In the embodiment of the present disclosure, the direction marker 120 can also be a marker of multiple feasible configurations with different imaging characteristics, or a marker of multiple feasible configurations with different imaging characteristics can be vertically spliced ​​into a whole to achieve a direction indication effect. In this case, markers of different configurations can be used to cross-verify the directions they indicate, thereby improving the accuracy of the direction indication.

[0087] Optionally, the direction mark is made of metal or the surface of the direction mark is metal-plated, so that the direction of the directional electrode can be identified by utilizing the development effect of metal in the image.

[0088] The technical solution of the disclosed embodiment is to provide at least one group of directional electrode contacts on the wire body so that the directional electrode can perform electrical stimulation; and to provide a direction mark in the shape of an arc on the wire body, the direction mark including a first mark arc and a second mark arc, with a first gap between the first mark arc and the second mark arc, so that an artifact corresponding to the direction mark and capable of indicating the direction of the directional electrode can be seen in the medical image, thereby realizing the direction identification of the directional electrode through the artifact.

[0089] In order to better understand the technical solution of the above-mentioned embodiment of the present disclosure, an optional example is provided here. Figure 8The directional electrode includes a wire body and a direction marker, at least one group of directional electrode contacts is arranged on the wire body, the direction marker is arranged on the wire body in an arc shape, the direction marker includes a first marker arc, a second marker arc and a connecting portion, there is a first gap between the first marker arc and the second marker arc, and the distance range between the directional electrode contact and the direction marker is [2 mm, 12 mm].

[0090] Fig. 9 1 is a flow chart of a method for designing a direction sign provided in an embodiment of the present disclosure. This embodiment is applicable to the case of designing a direction sign. The method can be executed by a direction sign design device provided in an embodiment of the present disclosure, and the device can be implemented by software and / or hardware, and the device can be integrated in an electronic device, and the electronic device can be various user terminals or servers.

[0091] See also Fig. 9 The method of the embodiment of the present disclosure specifically includes the following steps:

[0092] S210. Determine at least one group of alternative logo design schemes, and for each group of alternative logo design schemes in the at least one group of alternative logo design schemes, simulate to obtain an alternative simulation image of the alternative logo design scheme, wherein the alternative simulation image is an image obtained by simulating the captured image of the alternative logo, and the alternative logo is a logo corresponding to the alternative logo design scheme of the direction logo to be designed.

[0093] Among them, the alternative identification design scheme is an alternative design scheme for the directional identification in the directional electrode provided by any embodiment of the present disclosure; the alternative design scheme may be a scheme for an alternative identification with an asymmetric design in structure, so that the alternative identification can introduce asymmetric characteristics into the result obtained by performing image acquisition on it, so as to realize the orientation identification of the directional electrode. The alternative identification is the identification corresponding to the alternative identification design scheme, that is, the alternative identification is the identification that can be manufactured according to the alternative identification design scheme. The acquired image is the image obtained by performing medical image acquisition on the alternative identification; the acquired image may be, for example, a CT image; the acquisition method of the acquired image may be, for example, a CT scan.

[0094] In the embodiment of the present disclosure, at least one set of alternative logo design solutions can be manually designed; or at least one set of alternative logo design solutions can be automatically generated according to the design solution generation rule. For example, the design solution generation rule is that the corresponding arc shape angle range of the alternative logo is within [first angle, second angle], and the alternative logo includes a third gap within a preset range such as [0, 5], and the alternative logo is asymmetric. In the embodiment of the present disclosure, the method for determining at least one set of alternative logo design solutions is not specifically limited.

[0095] In the embodiments of the present disclosure, see Fig.10 The alternative logo design scheme can be presented in the form of a plane picture, for example, representing the structure of the alternative logo corresponding to the alternative logo design scheme in the cross section. The white area in the plane picture can be the area corresponding to the alternative logo; the gray area is the soft tissue components such as brain tissue and cerebrospinal fluid to simulate the head; the black area is the air area, that is, the air area outside the simulated head.

[0096] In the disclosed embodiment, the alternative identification design scheme may include a design scheme that uses the electrode contact of the directional electrode as an alternative identification scheme, that is, there may be an alternative identification design scheme that does not require setting an additional identification on the directional electrode as an alternative identification.

[0097] For example, see Fig.11 , Fig.12 and Fig.13 At least one set of alternative identification design schemes can be determined, each set of alternative identification design schemes can include a text description of specific design parameters of the alternative identification design scheme, a three-dimensional image of the alternative identification and the structure of the alternative identification in the cross section, at least one set of alternative identification design schemes includes alternative identification design schemes with additional design parameters of 60°, 120°, 180°, 180° notch 30°, 180° notch 30°, right side metal sheet doubled thickened, 180° notch 60° right side metal sheet doubled thickened, 240°, 240° notch 30°, 240° notch 60° and 300°, and the design parameters of using electrode contacts as alternative identifications are respectively one of the contacts doubled thickened and three equally large and evenly distributed electrode contacts (i.e. Fig.13 for each set of alternative identification design schemes in at least one set of alternative identification design schemes, simulation is performed to obtain alternative simulation images of the alternative identification design schemes, and the alternative simulation images are also Fig.11 , Fig.12 and Fig.13 The rightmost image in the figure is a simulated image that can characterize the metal artifact characteristics of the configuration of the alternative logo in the CT scan. It should be noted that the above examples of 240° gap 60°, etc. are text descriptions of specific design parameters of the alternative logo design scheme, which can be specifically understood as the configuration of the alternative logo corresponding to the alternative logo design scheme is a 240° arc with a 60° arc third gap therein.

[0098] It should be noted that metal will produce unique metal artifacts in medical images such as CT images. The characteristics of the artifacts are related to the CT imaging principle, as well as the projection, refraction and diffraction characteristics of metal to X-rays. Since metal artifacts are particularly likely to be affected by the environment in which they are located, the imaging characteristics of the physical system composed of metal, soft tissue (simulating brain tissue and cerebrospinal fluid) and air area can be used to simulate alternative simulation images of alternative logo design schemes. For example, based on the CT imaging principle, the projection characteristics of metal to X-rays, the refraction characteristics of metal to X-rays, the diffraction characteristics of metal to X-rays, the soft tissue At least one of the imaging characteristics of the air region during the CT scanning process and the imaging characteristics of the air region during the CT scanning process is simulated by computer simulation of the alternative simulation image of the alternative identification design scheme to predict the imaging characteristics of the alternative identification corresponding to the alternative identification design scheme in the CT scanning, so that it is possible to observe whether the metal artifacts of the alternative identification with light and dark alternations can play a role in specifying a specific orientation according to the alternative simulation image, that is, to facilitate artificial or automatic and active manipulation of the imaging characteristics of the physical system in the CT scanning, especially to use the imaging artifacts of the metal parts to play a role in indicating the orientation of the physical system. In the embodiments of the present disclosure, the method of simulating and obtaining the alternative simulation image of the alternative identification design scheme is not specifically limited.

[0099] S220. Determine a target identification design scheme for a directional identification from at least one group of alternative identification design schemes according to the alternative simulation images corresponding to the at least one group of alternative identification design schemes, so as to determine the structure of the directional electrode provided in any embodiment of the present disclosure according to the target identification design scheme.

[0100] Among them, the target identification design scheme is an alternative identification design scheme for manufacturing the directional identification in the directional electrode provided in any embodiment of the present disclosure.

[0101] Combined with the above-mentioned examples of at least one group of alternative logo design schemes determined, illustratively, according to the alternative simulation images corresponding to at least one group of alternative logo design schemes, it can be seen that the imaging pointing effect of the configuration of the alternative logo corresponding to the alternative logo design scheme with additional design parameters of 240° notch 60°, 240° notch 30° and 180° notch 60° is the best, and the imaging pointing effect of the configuration of the alternative logo corresponding to the alternative logo design scheme with additional design parameters of 240° notch 60° is the best among these three alternative logo design schemes. Therefore, the alternative logo design scheme with additional design parameters of 240° notch 60° can be used as the target logo design scheme, or, any one of the alternative logo design schemes with additional design parameters of 240° notch 60°, 240° notch 30° and 180° notch 60° can be used as the target logo design scheme. In the embodiments of the present disclosure, there is no specific limitation on the method of determining the target logo design scheme from at least one group of candidate logo design schemes according to the candidate simulation images respectively corresponding to at least one group of candidate logo design schemes.

[0102] Exemplarily, when the target identification design scheme is an alternative identification design scheme of an alternative identification with additionally set design parameters of 240° and 60°, the structure of the directional electrode provided in any embodiment of the present disclosure can be determined, especially the structure of the directional identification in the directional electrode provided in any embodiment of the present disclosure can be determined, and the structure of the directional identification in the cross section of the directional identification is as follows: Fig.14 As shown, see Fig.15 , the directional markings obtained by manufacturing are photographed by CT at multiple angles to obtain the marking images at multiple angles. Fig.15 It can be seen that the direction mark can produce a dark line in the direction of the 60° notch, and the metal sheets on the marking parts on both sides of the direction mark correspond to the other two dark lines. The three together constitute a specific "⊥"-shaped dark line mark, and the white arrow indicates the direction. Therefore, the direction mark has an imaging pointing effect and has the ability to indicate direction.

[0103] The technical solution of the embodiment of the present disclosure determines at least one group of alternative identification design schemes, and for each group of alternative identification design schemes in at least one group of alternative identification design schemes, simulates to obtain alternative simulation images of the alternative identification design schemes, wherein the alternative simulation image is an image obtained by simulating the captured image of the alternative identification, and the alternative identification is the identification corresponding to the alternative identification design scheme of the direction identification to be designed, so as to determine the target identification design scheme through the alternative simulation image; according to the alternative simulation images corresponding to at least one group of alternative identification design schemes, the target identification design scheme of the direction identification is determined from at least one group of alternative identification design schemes, so as to determine the structure of the directional electrode provided by any embodiment of the present disclosure according to the target identification design scheme, and the direction identification with the best directivity can be determined through the target identification design scheme. The above technical solution can determine the target identification design scheme that can make the direction identification with the best directivity from at least one group of alternative identification design schemes through the alternative simulation images corresponding to at least one group of alternative identification design schemes, thereby improving the accuracy of the direction recognition of the directional electrode.

[0104] An optional technical solution, according to the alternative simulation images corresponding to at least one group of alternative logo design schemes, determines a target logo design scheme for a directional logo from at least one group of alternative logo design schemes, comprising: determining first logo feature parameters of the alternative simulation images corresponding to at least one group of alternative logo design schemes, wherein the first logo feature parameters at least include the number of symmetry axes of the alternative simulation images; and using the alternative logo design scheme in which the number of symmetry axes is less than or equal to 1 in at least one group of alternative logo design schemes as the target logo design scheme for the directional logo.

[0105] The first identification characteristic parameter is a parameter related to the characteristics of the candidate identification in the candidate simulation image. The number of symmetry axes is the number of symmetry axes in the region corresponding to the candidate identification in the candidate simulation image.

[0106] It is understandable that the candidate logo will produce unique artifacts in the candidate simulation image, and the first logo feature parameter can be determined based on the unique features of the artifacts in the candidate simulation image. For example, the first logo feature parameter can be determined based on at least one of the positions, orientations, occupied areas, and sizes corresponding to the extracted dark lines and / or bright areas in the candidate simulation image. In the embodiment of the present disclosure, there is no specific limitation on the method of determining the first logo feature parameters of the candidate simulation images corresponding to at least one group of candidate logo design solutions.

[0107] In the embodiment of the present disclosure, for example, at least one of the at least one set of alternative identification design schemes in which the number of symmetry axes is less than or equal to 1 can be used as the target identification design scheme for the direction identification; for another example, from at least one of the at least one set of alternative identification design schemes in which the number of symmetry axes is less than or equal to 1, an alternative identification design scheme is determined as the target identification design scheme. In the embodiment of the present disclosure, there is no specific limitation on the manner of using the at least one set of alternative identification design schemes in which the number of symmetry axes is less than or equal to 1 as the target identification design scheme for the direction identification.

[0108] In the embodiment of the present disclosure, by using at least one group of alternative identification design schemes in which the number of symmetry axes is less than or equal to 1 as the target identification design scheme for the directional identification, it is possible to determine the target identification design scheme that can optimize the directionality of the directional identification, thereby improving the accuracy of the direction recognition of the directional electrode.

[0109] Based on the above scheme, another optional technical scheme is that the first identification feature parameter also includes image size and image clarity; taking the alternative identification design scheme with the number of symmetry axes less than or equal to 1 in at least one group of alternative identification design schemes as the target identification design scheme for the direction identification, including: when the number of alternative identification design schemes with the number of symmetry axes less than or equal to 1 in at least one group of alternative identification design schemes is equal to 1, taking the alternative identification design scheme with the number of symmetry axes less than or equal to 1 as the target identification design scheme for the direction identification; determining the target identification design scheme for the direction identification from at least one group of alternative identification design schemes according to the alternative simulation images corresponding to the at least one group of alternative identification design schemes, and also including: when the number of alternative identification design schemes with the number of symmetry axes less than or equal to 1 in at least one group of alternative identification design schemes is greater than 1, taking each alternative identification design scheme with the number of symmetry axes less than or equal to 1 as a candidate design scheme, and determining the target identification design scheme for the direction identification from at least two candidate design schemes according to the image size and image clarity corresponding to the at least two candidate design schemes obtained.

[0110] The image size is the size of the candidate simulation image. The image clarity is the clarity of the candidate simulation image. The candidate design scheme is the candidate logo design scheme that is selected as the target logo design scheme.

[0111] In an embodiment of the present disclosure, when the number of alternative identification design schemes with a number of symmetry axes less than or equal to 1 in at least one group of alternative identification design schemes is equal to 1, the only alternative identification design scheme with a number of symmetry axes less than or equal to 1 can be used as the target identification design scheme for the direction identification.

[0112] In the embodiment of the present disclosure, considering that only one target identification design scheme is actually needed to determine the structure of the directional electrode, therefore, in the case that the number of the alternative identification design schemes with the number of symmetry axes less than or equal to 1 in at least one group of alternative identification design schemes is greater than 1, each alternative identification design scheme with the number of symmetry axes less than or equal to 1 can be used as a candidate design scheme, and the target identification design scheme of the directional identification can be determined from the at least two candidate design schemes according to the image size and image clarity corresponding to the obtained at least two candidate design schemes, for example, the candidate design scheme corresponding to the alternative simulation image with the largest image size and / or the highest image clarity can be used as the target identification design scheme; for another example, the weights corresponding to the image size and image clarity can be determined, the product of the quantized image size and the corresponding weight and the product of the quantized image clarity and the corresponding weight can be added to obtain the addition result, and the candidate design scheme corresponding to the alternative simulation image with the largest addition result can be used as the target identification design scheme; and so on. In the embodiment of the present disclosure, there is no specific limitation on the method of determining the target identification design scheme of the directional identification from the at least two candidate design schemes according to the image size and image clarity corresponding to the obtained at least two candidate design schemes. In the embodiment of the present disclosure, when the number of alternative identification design schemes with the number of symmetry axes less than or equal to 1 in at least one group of alternative identification design schemes is greater than 1, each alternative identification design scheme with the number of symmetry axes less than or equal to 1 is taken as a candidate design scheme, and based on the image size and image clarity corresponding to the at least two candidate design schemes obtained, a target identification design scheme for the directional marker is determined from the at least two candidate design schemes. The target identification design scheme that can optimize the directionality of the directional marker can be determined, thereby improving the accuracy of direction recognition of the directional electrode.

[0113] Fig.16 1 is a flow chart of a directional electrode orientation recognition method provided in an embodiment of the present disclosure. This embodiment is applicable to the case of directional electrode orientation recognition. The method can be executed by a directional electrode orientation recognition device provided in an embodiment of the present disclosure, and the device can be implemented by software and / or hardware, and the device can be integrated in an electronic device, and the electronic device can be various user terminals or servers.

[0114] See also Fig.16 The method of the embodiment of the present disclosure specifically includes the following steps:

[0115] S310, obtaining a medical image of a user who has implanted the directional electrode provided by any embodiment of the present disclosure, a plurality of reference simulation images corresponding to the direction identification in the directional electrode, and a reference orientation corresponding to each reference simulation image.

[0116] The medical image is obtained by collecting images of the direction markings of the directional electrodes in the body of a user in which the directional electrodes have been implanted. The medical image can also be obtained by collecting images of the directional electrodes in the body of the user; the medical image can be, for example, a CT image. The reference simulation image is an image obtained by simulating the collected image of the direction marking; the reference simulation image can be, for example, an alternative simulation image corresponding to the direction marking. The reference orientation is the orientation of the directional electrode represented by the reference simulation image.

[0117] It should be noted that the multiple reference simulation images can be obtained by simulating medical images of directional electrodes in multiple different reference orientations.

[0118] S320, performing image matching on the medical image and a plurality of reference simulation images respectively, and identifying the electrode orientation of the directional electrode implanted in the user's body according to the reference orientation corresponding to the successfully matched reference simulation image.

[0119] The electrode orientation is the orientation of the directional electrode.

[0120] It is understandable that the areas of direction markings in the medical image corresponding to directional electrodes of different orientations may be different, and the difference in the areas of direction markings generally lies in the difference in rotation angles. Therefore, the medical image is image matched with multiple reference simulation images respectively, and the reference simulation images of directional electrodes of different reference orientations and the medical image are matched for similarity, so that the reference orientation corresponding to the successfully matched reference simulation image is the electrode orientation of the directional electrode. In the disclosed embodiment, the method of identifying the electrode orientation of the directional electrode implanted in the user's body according to the reference orientation corresponding to the successfully matched reference simulation image is not specifically limited.

[0121] Exemplarily, a plurality of reference simulation images of a medical image may be overlapped and matched respectively, and a reference orientation corresponding to a successfully matched reference simulation image may be mapped onto the medical image, and the reference orientation mapped onto the medical image may be used as the electrode orientation.

[0122] The technical solution of the embodiments of the present disclosure obtains a medical image of a user who has implanted a directional electrode provided by any embodiment of the present disclosure, multiple reference simulation images corresponding to the direction identification in the directional electrode, and a reference orientation corresponding to each reference simulation image, so as to clarify the medical image, the reference simulation image, and the reference orientation; the medical image is image matched with the multiple reference simulation images respectively, and the electrode orientation of the directional electrode implanted in the user's body is identified according to the reference orientation corresponding to the successfully matched reference simulation image, thereby realizing orientation identification of the directional electrode. The above technical solution can realize accurate orientation identification of the directional electrode by image matching the medical image with multiple reference simulation images, and identifying the electrode orientation of the directional electrode implanted in the user's body according to the reference orientation corresponding to the successfully matched reference simulation image.

[0123] An optional technical solution, obtaining multiple reference simulation images corresponding to directional identifiers in a directional electrode and reference orientations corresponding to each reference simulation image, including: obtaining multiple reference orientations of the directional electrode based on a reference orientation of the directional electrode; obtaining reference simulation images corresponding to the directional identifiers of the directional electrode under multiple reference orientations, wherein the reference simulation image at least includes a portion corresponding to the directional identifier of the directional electrode.

[0124] Here, the reference orientation is an orientation serving as a reference for the orientation of the directional electrodes.

[0125] In the embodiment of the present disclosure, for example, the reference orientation may be rotated at multiple angles to obtain multiple reference orientations of the directional electrodes. In the embodiment of the present disclosure, the method of obtaining multiple reference orientations of the directional electrodes based on the reference orientation of the directional electrodes is not specifically limited.

[0126] In the disclosed embodiment, the medical images of the directional markings of the directional electrodes under multiple reference orientations can be simulated respectively to obtain reference simulation images corresponding to the directional markings of the directional electrodes under multiple reference orientations. In the disclosed embodiment, the method of obtaining the reference simulation images corresponding to the directional markings of the directional electrodes under multiple reference orientations is not specifically limited.

[0127] In the disclosed embodiment, by acquiring reference simulation images corresponding to the direction identification of the directional electrode under multiple reference orientations, a basis is provided for multiple reference simulation images required in the process of directional electrode orientation identification, thereby facilitating the realization of directional electrode orientation identification.

[0128] Another optional technical solution, a directional electrode orientation recognition method, further includes: obtaining a second identification feature parameter of each reference simulation image, and establishing a corresponding relationship between the second identification feature parameter and the reference orientation of the reference simulation image; performing image matching on the medical image with multiple reference simulation images respectively, including: performing image matching on the medical image with multiple reference simulation images respectively according to the second identification feature parameters corresponding to the multiple reference simulation images respectively; identifying the electrode orientation of the directional electrode implanted in the user's body according to the reference orientation corresponding to the successfully matched reference simulation image, including: identifying the electrode orientation of the directional electrode implanted in the user's body according to the reference orientation corresponding to the successfully matched reference simulation image and the corresponding relationship.

[0129] Among them, the second identification feature parameter is a characteristic parameter of the direction identification in the reference simulation image, that is, the second identification feature parameter can be used to point to the reference orientation in the reference simulation image; the second identification feature parameter can, for example, be at least one of the image orientation, the position of a recognizable part, and the orientation of the axis of symmetry, etc.

[0130] In the embodiment of the present disclosure, the method of obtaining the second identification characteristic parameter may be the same as or different from the method of determining the first identification characteristic parameter. In the embodiment of the present disclosure, the method of obtaining the second identification characteristic parameter is not specifically limited.

[0131] Exemplarily, when the second identification feature parameter is the orientation of the symmetry axis, the orientation of the symmetry axis can be associated with the reference orientation. For example, the direction of the dark line in the orientation of the symmetry axis can be used as the reference orientation, so as to establish a corresponding relationship between the second identification feature parameter and the reference orientation of the reference simulation image based on the established association. In the disclosed embodiment, the method for establishing the corresponding relationship between the second identification feature parameter and the reference orientation of the reference simulation image is not specifically limited.

[0132] In the embodiment of the present disclosure, the image features corresponding to the reference simulation image and the medical image can be identified according to each of the multiple reference simulation images and the second identification feature parameter of the reference simulation image, and the image features corresponding to the reference simulation image and the medical image can be matched. In the implementation of the present disclosure, the manner of matching the medical image with the multiple reference simulation images according to the second identification feature parameters corresponding to the multiple reference simulation images is not specifically limited.

[0133] Exemplarily, when the second identification feature parameter is the orientation of the symmetry axis, the symmetry axes corresponding to the reference simulation image and the medical image can be identified. When the orientations of the symmetry axes corresponding to the reference simulation image and the medical image are the same, it can be considered that the reference simulation image and the medical image are successfully matched.

[0134] In the embodiment of the present disclosure, the image features of the medical image and the reference orientation corresponding to the successfully matched reference simulation image can be correlated according to the corresponding relationship, and the electrode orientation of the directional electrode implanted in the user can be identified according to the result of the corresponding relationship. In the embodiment of the present disclosure, the electrode orientation of the directional electrode implanted in the user can be identified according to the reference orientation corresponding to the successfully matched reference simulation image and the corresponding relationship.

[0135] Exemplarily, when the second identification feature parameter is the orientation of the symmetry axis and the corresponding relationship is to use the direction of the dark line in the orientation of the symmetry axis as the reference orientation, the direction of the dark line in the orientation of the symmetry axis of the medical image is determined according to the corresponding relationship, and the direction of the dark line and the reference orientation corresponding to the successfully matched reference simulation image are corresponded, and the electrode orientation of the directional electrode implanted in the user's body is identified according to the correspondence result.

[0136] In the disclosed embodiment, the medical image can be matched with a plurality of reference simulation images respectively through the second identification feature parameter, and the electrode orientation of the directional electrode implanted in the user's body can be identified through the corresponding relationship, so as to improve the accuracy of the determined reference orientation.
