Description

Technical Field

[0001] This invention relates to the field of physical therapy technology for relieving muscle spasms and pain, and specifically to a precision treatment system for localized muscle spasms. Background Technology

[0002] In the fields of clinical rehabilitation medicine, neurology, and pain management, muscle spasm is a common pathological condition that significantly impacts patients' quality of life. It is typically caused by damage to the central nervous system (such as stroke, spinal cord injury, and multiple sclerosis) or peripheral neuropathy, manifesting as involuntary, excessive muscle tension or contraction, often accompanied by severe pain. Traditional treatments include oral muscle relaxants, physical therapy, botulinum toxin injections, and surgical intervention. Oral medications often have systemic side effects, such as drowsiness and fatigue, and are not very effective for localized spasms; physical therapy, while non-invasive, has limited effectiveness for moderate to severe spasms and a slow onset of action; botulinum toxin injections are currently a relatively effective local treatment, but their mechanism of action involves chemically blocking the neuromuscular junction, which carries drawbacks such as the risk of drug diffusion, potential antibody production leading to decreased efficacy, high cost, and limited duration of action (usually 3-6 months). Therefore, there is an urgent clinical need for a safer, more precise, less side-effect-prone, and more repeatable local physical intervention.

[0003] The core challenge in precise local treatment of muscle spasms lies in accurately locating the spastic muscle bundles or trigger points (pain points). Currently, commonly used clinical methods rely primarily on the physician's palpation experience and the patient's pain feedback, i.e., pressing with the fingers to locate nodules, cord-like structures, or tender points within the muscle. This method is highly subjective, heavily dependent on the operator's skill level, has poor repeatability, and is difficult to apply to deep muscles or obese patients, easily leading to inaccurate treatment, affecting efficacy, and even causing unnecessary tissue damage. Furthermore, palpation alone cannot quantify the degree of muscle stiffness or spasm state, making it difficult to objectively assess and compare the effects before and after treatment. Summary of the Invention

[0004] This invention was made to solve the above-mentioned problems, and its purpose is to provide a precise treatment system for local muscle spasms.

[0005] Neuromuscular hydrolysis is an emerging minimally invasive interventional treatment method commonly used in the treatment of peripheral nerve entrapment diseases. Its basic principle involves injecting a small amount of fluid into the space between the entrapped nerve and surrounding tissues using a needle. Through the mechanical separation effect of the fluid, the distance between the compressed nerve and surrounding tissues and fascia is increased, relieving nerve compression symptoms and improving the microenvironment for nerve regeneration.

[0006] Ultrasonic elastography technology reflects the stiffness or elasticity of tissues by assessing the deformation produced by tissues after mechanical stimulation. It can non-invasively, in real time, and visually display the distribution of muscle stiffness, thereby accurately identifying muscle areas that are abnormally stiff due to spasm.

[0007] The inventors of this invention have discovered that combining the stiffness distribution information obtained from ultrasound elastography with neuromuscular hydrolysis injection technology can construct an integrated system from precise diagnosis to targeted treatment. Specifically, ultrasound elastography accurately identifies the core stiff area of ​​spastic muscles as the treatment target, and neuromuscular hydrolysis injection technology provides precise physical intervention to this target. The injected treatment fluid is physiological saline. Unlike chemical agents such as botulinum toxin, physiological saline, although not a drug, can still effectively exert its therapeutic effect through the hydrolysis mechanism, and it has advantages such as easy availability, low cost, and ease of clinical application.

[0008] Based on the above findings, the present invention provides a precision treatment system for localized muscle spasms, which is used to relieve localized muscle spasms. The system comprises: a treatment fluid; an ultrasound imaging device for performing ultrasound imaging on the target muscle area and identifying the core area with the highest hardness value within the target muscle area as the treatment target point; and an injection device for delivering the treatment fluid to the treatment target point to perform water separation in the area where the treatment target point is located, thereby relieving localized muscle spasms. The treatment fluid is physiological saline.

[0009] The precision treatment system for localized muscle spasm provided by this invention may also have the following features: the ultrasound imaging device includes: an ultrasound elastography module, including an ultrasound probe, for applying mechanical or acoustic radiation force to the target muscle region, acquiring deformation data of the tissue in the target muscle region, and generating an ultrasound elastography image reflecting the tissue stiffness distribution based on the deformation data; and a target localization module, communicatively connected to the ultrasound elastography module, for receiving the ultrasound elastography image, identifying areas with abnormally high stiffness values ​​in the ultrasound elastography image, and locating the core area with the highest stiffness value within the area as the treatment target.

[0010] The precision treatment system for local muscle spasm provided by the present invention may also have the following features: the target localization module includes an image analysis unit, which is used to extract the corresponding hardness value according to the color code of each pixel in the ultrasound elastic image and the preset color mark mapping relationship, and to identify the area where the hardness value exceeds the preset threshold as the area with abnormally high hardness value, and to locate the position corresponding to the maximum hardness value in the area as the treatment target.

[0011] The precision treatment system for local muscle spasm provided by the present invention may also have the following features: the ultrasound imaging device further includes a real-time navigation module, which is communicatively connected to the ultrasound elastography module and the target positioning module, and is used to overlay the position information of the treatment target onto the real-time ultrasound image and generate the needle insertion path.

[0012] The precision treatment system for local muscle spasm provided by the present invention may also have the following features: the ultrasound elastography module has a B-mode ultrasound imaging mode for acquiring B-mode ultrasound anatomical images of the target muscle region, and the real-time navigation module overlays the ultrasound elastography image onto the B-mode ultrasound anatomical image of the target muscle region in a color-coded form, and marks the location information of the treatment target point in the overlaid image.

[0013] The precision treatment system for localized muscle spasm provided by the present invention may also have the following feature: the injection device includes a puncture needle, which is used to travel along the needle insertion path to the treatment target location under the guidance of a real-time navigation module.

[0014] The precision treatment system for localized muscle spasm provided by the present invention may also have the following feature: wherein the puncture needle is a fine-diameter puncture needle with a diameter of 25G or 27G.

[0015] The precision treatment system for localized muscle spasm provided by the present invention may also have the following feature: the injection device further includes a guide frame for guiding the puncture needle along the needle insertion path.

[0016] The precision treatment system for localized muscle spasm provided by the present invention may also have the following feature: the injection device further includes a control module, which is communicatively connected to the real-time navigation module, and is used to control the injection device to start the injection action when the tip of the puncture needle reaches the treatment target point, so as to deliver physiological saline to the treatment target point.

[0017] The precision treatment system for local muscle spasm provided by the present invention may also have the following features: the ultrasound imaging device further includes an injection assessment module, which is communicatively connected to the ultrasound elastography module. After the injection device completes the injection action, the ultrasound elastography module acquires the post-injection ultrasound elastography image of the area where the treatment target is located, compares the post-injection ultrasound elastography image with the ultrasound elastography image acquired before injection, and outputs information on the change in hardness value.

[0018] The role and effect of invention

[0019] The precision treatment system for localized muscle spasm according to the present invention has the following beneficial effects:

[0020] This invention deeply integrates the precise positioning capabilities of ultrasound elastography with neuromuscular hydrolysis injection technology, achieving precise control over the entire process of treating spastic muscles, from visual diagnosis to real-time guided treatment. This effectively overcomes the subjectivity and inaccuracy of traditional palpation-based positioning, significantly improving the success rate of target point hits and thus enhancing treatment efficacy and stability. This invention uses physiological saline as the treatment fluid, physically separating abnormal adhesions between the muscle and surrounding tissues through the hydrolysis effect to relieve muscle spasms and pain. Unlike chemical agents such as botulinum toxin, physiological saline, while not a drug, can still effectively exert its therapeutic effect through the hydrolysis mechanism, and it has advantages such as easy availability, low cost, and ease of clinical application. Furthermore, compared to the chemical blocking mechanism of botulinum toxin, this invention does not involve the risk of drug toxicity or immune reactions, making treatment safer and allowing for frequent repetition without being limited by the duration of drug action.

[0021] Furthermore, this invention utilizes the same ultrasound elastography technology to compare and evaluate muscle stiffness before and after injection. The injection assessment module acquires a post-injection ultrasound elastography image after injection, compares it with the pre-injection image to determine stiffness values, and outputs information on changes in stiffness, achieving real-time objective evaluation of the treatment effect. Simultaneously, it incorporates subjective symptom assessment and functional assessment, verifying the treatment effect from multiple dimensions. This forms a complete closed loop of "image localization - precise injection - effect verification," providing closed-loop verification for treatment and a basis for subsequent treatment decisions, making the entire treatment process more data-driven, standardized, and reliable.

Detailed Implementation

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the following embodiments, in conjunction with the accompanying drawings, provide a detailed description of the precise treatment system for local muscle spasms of this invention.

[0031] Figure 1 This is a block diagram of a precision treatment system for localized muscle spasms in an embodiment of the present invention.

[0032] This embodiment provides a precision treatment system 100 for localized muscle spasms (hereinafter referred to as the precision treatment system), used to relieve localized muscle spasms, such as... Figure 1 As shown, it includes an ultrasound imaging device 1, an injection device 2, and a treatment liquid 3.

[0033] Figure 2 This is a block diagram of an ultrasound imaging device in an embodiment of the present invention.

[0034] like Figure 2 As shown, the ultrasound imaging device 1 is used to perform ultrasound imaging on the target muscle area and identify the core area with the highest hardness value in the target muscle area as the treatment target point. It includes an ultrasound elastography module 101, a target point positioning module 102, a real-time navigation module 103, and an injection assessment module 104.

[0035] Specifically, the method for identifying the target muscle area is as follows: For patients whose local muscle spasms are caused by a clear trigger (such as trauma, stiff neck, or prolonged poor posture) and have resulted in specific postural abnormalities or limited joint mobility, a detailed medical history and clinical physical examination are conducted. Through questioning and initial palpation, the physician identifies the area of ​​pain and the joints or muscle groups with limited function, such as head and neck tilting caused by trapezius muscle spasm in the neck, or limited lumbar mobility caused by erector spinae muscle spasm in the lumbar region. This aims to initially define the target muscle area that requires further precise imaging assessment.

[0036] The ultrasonic elastography module 101 includes an ultrasonic probe for applying mechanical or acoustic radiation force to the target muscle region, acquiring and processing deformation data generated by the tissue in the target muscle region in real time, and generating an ultrasonic elastography image covering the scanned area and reflecting the tissue stiffness distribution based on the deformation data.

[0037] The ultrasound elastography module 101 also features a B-mode ultrasound imaging mode for acquiring B-mode ultrasound anatomical images of the target muscle region. The real-time navigation module 103 is communicatively connected to the ultrasound elastography module 101, and displays the ultrasound elastography images in color-coded form on the B-mode ultrasound anatomical images. For example, red represents areas with higher hardness and blue represents areas with lower hardness, thus intuitively reflecting the spatial distribution of relative tissue hardness.

[0038] The target localization module 102 is communicatively connected to the ultrasonic elastography module 101. It is used to receive ultrasonic elastography images and identify areas with abnormally high hardness values ​​in the ultrasonic elastography images. The core area with the highest hardness value within the area is located as the treatment target.

[0039] The target localization module 102 includes an image analysis unit, which specifically achieves treatment target localization in the following way: It acquires the color-coded values ​​of each pixel in the ultrasound elastography image, and converts each pixel's color-coded value into a corresponding hardness value according to a preset color-coded mapping relationship, thereby obtaining hardness value distribution data covering the entire scanned area. The hardness value of each pixel is compared with a preset threshold to identify areas where the hardness value exceeds the preset threshold, i.e., areas with abnormally high hardness values. Within these areas, the location corresponding to the maximum hardness value is selected as the treatment target.

[0040] Through the automated processing of the aforementioned image analysis unit, the precision treatment system 100 can quantitatively and objectively identify the core stiff area of ​​the spastic muscle from the ultrasound elastography image.

[0041] In practical applications, ultrasound elastography images are displayed on a display device. By observing these images, doctors can intuitively identify the "responsible muscle" exhibiting abnormally high stiffness signals within a normally anatomically normal muscle group from a functional pathology perspective. They can also visually confirm the location of the treatment target point output by the image analysis unit. For example, in the ultrasound elastography image of the responsible muscle, can the core area with the highest stiffness value and the reddest color (or the hardest area indicated by a preset color scale) correspond to the location of the treatment target point output by the image analysis unit? This target point corresponds to the stiffest muscle bundle, the area with a high density of neuromuscular junctions, or the myofascial trigger point within the spastic muscle.

[0042] The real-time navigation module 103 is also connected to the target positioning module 102 to receive the location information of the treatment target and mark the location information of the treatment target on the real-time ultrasound image in the form of a marker, while generating the needle insertion path.

[0043] Figure 3 This is a block diagram of the injection device in an embodiment of the present invention.

[0044] like Figure 3As shown, the injection device 2 is used to deliver the treatment liquid 3 to the treatment target to perform water separation in the area where the treatment target is located and relieve local muscle spasm, including a puncture needle 201 and a guide frame 202.

[0045] The treatment fluid 3 is physiological saline. The puncture needle 201 is a fine-bore puncture needle with a diameter of 25G or 27G. In this embodiment, the guide frame 202 adjusts its angle according to the needle insertion path generated by the real-time navigation module 103 to guide the puncture needle 201 along the needle insertion path to the treatment target position. In practical applications, a free-hand technique can also be used, whereby the operator manually guides the puncture needle 201 according to real-time ultrasound images.

[0046] Figure 4 This is a real-time ultrasound image of the puncture needle during the treatment process in an embodiment of the present invention.

[0047] Specifically, such as Figure 4 As shown, under the real-time navigation and monitoring of the real-time navigation module 103, the ultrasound probe position is kept stable to continuously display the treatment target image. The operator, guided by the real-time ultrasound image, gradually advances the needle tip 201, which is connected to a syringe loaded with saline, along the needle insertion direction determined by the guide frame 202 (or using a free-hand technique) to the treatment target location, i.e., the core area with the highest hardness shown on the ultrasound elastic image. After confirming that the needle tip has reached the target, the operator slowly injects a predetermined amount of saline (1 to 4 mL). During the injection, the real-time ultrasound image shows an anechoic or hypoechoic area formed by the diffusion of saline in the treatment target area, i.e., the "water separation" effect: through the mechanical expansion force of the liquid, the abnormally tight contact between nerve endings and muscle fibers is physically separated, and / or the pathological adhesions between muscle fibers and surrounding fascia are loosened, thereby interrupting the abnormal neuromuscular feedback loop and relieving local tissue pressure.

[0048] In this embodiment, the injection device 2 further includes a control module 203, which is communicatively connected to the real-time navigation module 103. The control module 203 controls the injection device 2 to initiate the injection action when the tip of the puncture needle 201 reaches the treatment target, delivering a predetermined amount of saline solution to the treatment target, i.e., performing automatic injection. In practical applications, manual or automatic injection can be selected according to requirements.

[0049] The injection assessment module 104 is communicatively connected to the ultrasound elastography module 101. After the injection device 2 completes the injection action, the ultrasound elastography module 101 acquires the post-injection ultrasound elastography image of the area where the treatment target is located, compares the post-injection ultrasound elastography image with the ultrasound elastography image acquired before injection, and outputs information on the change in hardness value.

[0050] Specifically, changes in hardness are reflected in the image as a corresponding color change (e.g., from red to blue or green), meaning that the hardness value of the originally high-hardness core area decreases, thus objectively reflecting that the mechanical loosening effect of the injection has acted on the treatment target tissue.

[0051] In practical applications, after the injection is completed, the Precision Treatment System 100 can immediately perform multi-dimensional effect evaluation, forming a closed-loop treatment process.

[0052] Figure 5 This is a comparison of the hardness values ​​of ultrasound elastography images before and after treatment in an embodiment of the present invention.

[0053] (1) Imaging assessment: By analyzing the changes in hardness values ​​output by the injection assessment module 104, the changes in hardness of the treatment target area before and after injection can be quantitatively assessed, objectively reflecting the treatment effect. For example... Figure 5 As shown, the hardness value (KPa) of the ultrasound elastography image after injection decreased significantly compared with that before injection, objectively confirming the significant reduction in muscle hardness.

[0054] (2) Subjective symptom assessment: Ask the patient about changes in subjective pain sensation at the original pain site. The visual analog scale is usually used for quantitative comparison. Injection at the correct target point is often accompanied by a significant reduction or disappearance of pain.

[0055] (3) Functional assessment: The degree of improvement in the range of motion of the patient's restricted joints or abnormal posture can be assessed by methods such as joint range of motion measurement, for example, reassessing the rotation angle of the neck and the range of lumbar flexion. If the pain is relieved and the range of motion of the joints is improved immediately, it further confirms that the injection accurately hit the treatment target and the treatment produced a clear immediate effect.

[0056] The aforementioned multi-dimensional real-time feedback collectively verified the accuracy and effectiveness of the entire process of "image localization - precise injection - effect verification".

[0057] Figure 6 This is a flowchart illustrating the workflow of a precision treatment system for localized muscle spasms in an embodiment of the present invention.

[0058] like Figure 6 As shown, the specific workflow of this precision treatment system 100 is as follows:

[0059] S1: Through medical history inquiry and clinical physical examination, combined with preliminary palpation, determine the area of ​​pain and the joints or muscle groups with limited function as complained by the patient, and initially define the target muscle area.

[0060] S2: Place the ultrasound probe on the surface of the target area, start the ultrasound elastography module 101, and generate an ultrasound elastography image covering the scanned area.

[0061] S3: The target localization module 102 extracts hardness value distribution data based on the color coding of each pixel in the elastic image and the preset color mark mapping relationship, identifies the area with abnormally high hardness, and selects the position corresponding to the maximum hardness value as the treatment target.

[0062] S4: The real-time navigation module 103 marks the location information of the treatment target on the real-time ultrasound image in the form of a marker and generates the needle insertion path.

[0063] S5: Under real-time navigation and monitoring, the operator advances the puncture needle 201 along the needle insertion direction determined by the guide frame 202 (or uses free hand technique) to the treatment target position under the guidance of real-time ultrasound image. After confirming that the needle tip has arrived, a predetermined amount of physiological saline (1 to 4 mL) is injected to perform water separation.

[0064] S6: The injection evaluation module 104 acquires the ultrasound elasticity image after injection, compares the hardness value with the image before injection, and outputs the hardness value change information to verify the effect.

[0065] The role and effect of the embodiments

[0066] The precision treatment system for localized muscle spasm according to the present invention has the following beneficial effects:

[0067] This invention generates real-time ultrasound elastic images reflecting the distribution of tissue hardness using an ultrasound elastography module. It also identifies areas with abnormally high hardness values ​​based on the hardness distribution using a target localization module and locates the core area with the highest hardness value as the treatment target. This achieves visualization of target localization and overcomes the shortcomings of traditional palpation localization, such as strong subjectivity, poor repeatability, and difficulty in locating deep muscles. It significantly improves the accuracy of hitting the treatment target, thereby enhancing the treatment effect and stability.

[0068] This invention uses physiological saline as the treatment fluid, employing a water-separation effect to physically separate abnormal adhesions between muscles and surrounding tissues, thereby relieving muscle spasms and pain. Unlike chemical agents such as botulinum toxin, physiological saline, while not a drug itself, can still effectively exert its therapeutic effect through the water-separation mechanism, and has advantages such as easy availability, low cost, and ease of clinical application. Furthermore, compared to the chemical blocking mechanism of botulinum toxin, this invention does not involve the risks of drug toxicity or immune reactions, making the treatment safer and allowing for frequent repetition without being limited by the duration of drug action.

[0069] This invention utilizes an injection assessment module to acquire a post-injection ultrasound elastography image after injection, compares it with the pre-injection ultrasound elastography image to determine stiffness values, and outputs information on changes in stiffness values. This enables real-time, objective assessment of treatment effectiveness. Simultaneously, it incorporates subjective symptom assessment and functional assessment to verify treatment efficacy from multiple dimensions, providing closed-loop validation for treatment and a basis for subsequent treatment decisions. This makes the entire treatment process more data-driven, standardized, and reliable.

[0070] This invention integrates an ultrasound elastography module, a target localization module, a real-time navigation module, an injection assessment module, and an injection device into a collaborative precision treatment system. It achieves full-process coverage from image localization to precise injection to effect verification. The modules work together through communication connections, simplifying the operation process and lowering the technical threshold for treatment.

The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
