Description

Technical Field

[0001] This invention relates to the field of medical rehabilitation, and in particular to a method and device for postpartum pelvic repair using a combination of traditional Chinese and Western medicine. Background Technology

[0002] Postpartum pelvic floor repair is an important topic in obstetrics and gynecology and rehabilitation medicine. During childbirth, the pelvic floor muscles, fascia, and ligaments of women are prone to irreversible damage due to extreme stretching and traction, leading to pelvic floor dysfunction (PFD). Western clinical data shows that more than 60% of women who deliver vaginally have varying degrees of pelvic floor muscle laxity, with 30% experiencing serious complications such as uterine prolapse and urinary incontinence. Current mainstream treatment options include:

[0003] While procedures like anterior and posterior vaginal wall repair and pelvic floor reconstruction can improve anatomical structure in the short term, they have long-term sequelae such as a 15% postoperative infection rate and dyspareunia caused by scar contracture, and are expensive (average cost of over 20,000 yuan per surgery). Kegel exercises and biofeedback electrical stimulation devices can partially improve muscle strength, but they neglect the guidance of traditional Chinese medicine meridian theory and cannot solve chronic pelvic pain (CPP) caused by qi and blood stagnation. They are also highly dependent on these devices (requiring three professional training sessions per week). Acupressure and moxibustion can regulate qi and blood circulation, but they face three major technical bottlenecks: a disconnect between meridian and acupoint location and modern anatomical targets (e.g., the correspondence between the isococcal muscle and the Ren meridian is not clearly defined); a lack of quantitative standards for manipulation techniques (e.g., vague parameters such as vibration frequency and pressure depth); and a repair efficiency of less than 40% for structural injuries (e.g., levator ani muscle tears ≥3cm).

[0004] Clinical research shows that neither Western medicine nor traditional Chinese medicine alone can achieve full recovery of pelvic floor function, and there is an urgent need for innovative solutions that combine Western and traditional Chinese medicine in postpartum pelvic repair techniques and devices. Summary of the Invention

[0005] The purpose of this invention is to provide a method and device for postpartum pelvic repair that combines traditional Chinese and Western medicine.

[0006] To achieve the above objectives, this invention provides the following technical solution: a combined traditional Chinese and Western medicine postpartum pelvic floor repair technique and device. This claim proposes a combined traditional Chinese and Western medicine postpartum pelvic floor repair method, the core of which is to restore the pelvic floor's biomechanical balance by manually stimulating specific glands and muscle groups around the female birth canal. The specific operation includes four key steps: First, precisely locating the greater vestibular gland area (located on both sides of the vaginal opening, with the gland ducts opening between the hymen and labia minora) through palpation combined with ultrasound imaging; then performing treatment using a combination of circular finger pressure and longitudinal vibration. The pressure frequency is controlled at 30-50 times / minute, the pressure is maintained at 0.5-1.5 kgf, the vibration amplitude is 2-3 mm, the frequency is 80-100 Hz, and the treatment depth is strictly limited to 2-3 cm. This operation aims to promote glandular secretion through physical stimulation, alleviate glandular duct blockage and surrounding tissue adhesions caused by childbirth, and improve episiotomy wound pain and dryness; second, resistance training is performed on the deep and superficial transverse vulvar muscles (including the deep transverse vulvar muscle, superficial transverse vulvar muscle, and inguinal muscles). This method utilizes resistance bands to apply 50%-70% of maximum voluntary contraction force, employing a biofeedback training pattern that alternates between isometric contractions (lasting 5 seconds) and eccentric contractions (slow relaxation over 3 seconds) to enhance muscle strength and endurance. Biofeedback technology monitors electromyographic signals in real time to ensure training precision and effectively improve inflammation caused by vulvar insufficiency. It also involves dynamic traction and static holding of the inguinal ligament (originating from the pubic tubercle and inserting into the femoral trochanter) through mechanical intervention. The dynamic traction angle is controlled at 30°-60° and lasts for 10 seconds; the static holding phase is maintained for 5 seconds, and this repeated operation maintains the ligament's elastic modulus within the physiological range (1200-1500 MPa). This method enhances ligament flexibility, prevents pelvic tilt or prolapse caused by ligament laxity due to childbirth, and activates proprioceptive nerves in the perineal body region, using pressure sensors to monitor electromyographic signal intensity in real time. By setting trigger thresholds (resting potential ≤5μV, peak contraction ≥20μV) and combining visual feedback, patients are guided to complete targeted contraction training, enhancing the nerve's control over the pelvic floor muscles and improving postpartum muscle hypertonia or relaxation. Combining anatomical landmarks and imaging localization avoids the subjective errors of traditional methods, ensuring accurate treatment targets; it covers glandular function repair, muscle biomechanical reconstruction, ligament elasticity adjustment, and neural feedback regulation, forming a systematic treatment plan; quantitative parameters (frequency, pressure, angle, etc.) lower the operational threshold, ensuring clinical repeatability; and the depth of treatment and biomechanical parameters are strictly limited to avoid damage to surrounding tissues (such as the urethra and rectum).

[0007] Furthermore, the specific procedures for stimulating the vestibular glands are detailed:

[0008] The procedure employs a combination of circular pressure and vibration, with the depth controlled within 2-3 cm. During the procedure, the fingers use the lower edge of the pubic symphysis as a fulcrum to perform circular pressure along the gland's direction (frequency 30-50 times / minute), followed by longitudinal vibration (amplitude 2-3 mm, frequency 80-100 Hz). This is repeated for three cycles, followed by local heat application (temperature 40±2℃, duration 5 minutes). Circular pressure promotes glandular secretion, vibration accelerates the elimination of metabolic waste, and heat application further dilates local blood vessels, relieving pain and dryness at the episiotomy wound. The 2-3 cm depth avoids the urethra and rectum to prevent mechanical damage. Clinical data shows that this combined technique can increase vestibular gland secretion by three times and reduce the VAS pain score by 60%.

[0009] Furthermore, the deep and superficial striated muscle group training proposes a biofeedback training model: the training includes alternating isometric and eccentric contractions, with intensity adjusted according to surface electromyography (sEMG) signals. Specifically, it is divided into three levels: 30% assisted active contraction via instrument; resisted active contraction applying 60% of maximum contractile force; and overload burst training using 80% of maximum contractile force combined with shockwave stimulation. Real-time sEMG feedback adjusts training intensity to avoid muscle weakness or overload; eccentric contractions enhance muscle fiber recruitment, and shockwave stimulation promotes collagen remodeling and repairs levator ani muscle tears; after training, the maximum contractile force of the pelvic floor muscles increases by 40%, and the incidence of urinary incontinence decreases by 55%.

[0010] Furthermore, a combined dynamic traction and static maintenance method for inguinal ligament treatment is proposed: alternating dynamic traction (angle 30°-60°, frequency 0.5Hz) and static maintenance (holding for 5 seconds), combined with near-infrared spectroscopy (NIR) monitoring of ligament elastic modulus (target value 1200-1500MPa). Dynamic traction simulates the physiological range of motion, while static maintenance consolidates the repair effect; NIR technology monitors ligament elastic modulus in real time to avoid overstretching (>1500MPa, prone to rupture) or loosening (<1200MPa, prone to prolapse); ligament stiffness increases by 25% after treatment, reducing the risk of postpartum pelvic tilt.

[0011] Furthermore, pressure sensing technology is introduced to monitor the proprioceptive nerve activation status in the perineal body region: real-time monitoring of electromyographic (EMG) signal intensity is achieved through pressure sensors, trigger thresholds are set (resting potential ≤ 5 μV, contraction peak ≥ 20 μV), and visual feedback guides the patient to complete precise contractions. Setting EMG signal thresholds avoids ineffective contractions, improving training efficiency; visual feedback (such as screen EMG waveforms) enhances proprioceptive input, promoting central nervous system control of the pelvic floor muscles; and pelvic floor ischemia caused by excessive contraction is avoided (automatic alarm when EMG peak < 20 μV).

[0012] Furthermore, a three-dimensional strengthening training program for the external anal sphincter muscle group is proposed: including sagittal plane anal sphincter contraction (contraction duration ≥10 seconds), coronal plane lateral contraction (resistance training with 30% of maximum resistance), and horizontal plane rotational contraction (coordinated with pelvic pendulum movements). Training is conducted 5 times per week, with intervals of at least 48 hours between each session. Sagittal, coronal, and horizontal plane training covers the full range of functions of the external anal sphincter, avoiding the limitations of single-dimensional training; progressing gradually from basic contraction to resistance training, increasing sphincter closure pressure (from 60 cmH2O to 95 cmH2O); after training, the frequency of urinary incontinence decreased by 53%, and the rate of achieving the target level for anal sphincter coordination increased from 58% to 92%.

[0013] Furthermore, a hip flexion and external rotation resistance training method was proposed for piriformis muscle regulation: Patients inhale while flexing and abducting the hip to 45°, and exhale while externally rotating the hip joint to its endpoint and holding for 5 seconds. Each set is repeated 12 times, with 2 sets per day for 8 weeks. The training is synchronized with the respiratory rhythm. Contraction during exhalation enhances muscle recruitment efficiency, while relaxation during inhalation avoids over-fatigue. The hip flexion and external rotation position directly acts on the piriformis muscle, reducing the risk of sciatic nerve compression. After treatment, the piriformis muscle tenderness threshold increased from 2.3 kgf to 6.8 kgf, and the incidence of sciatica decreased by 72%.

[0014] Furthermore, a combined training program for isococcal muscle activation was proposed: combining bridging exercises (supine hip raises, held for 5 seconds x 10 repetitions) with bulbospongiosus electromyography (EMG) (frequency 100Hz, pulse width 200μs), requiring pelvic floor muscle contraction to be synchronized with the bridging movement, 3 times a week for 12 consecutive weeks. The bridging exercise strengthened the synergistic effect of the gluteus maximus and pelvic floor muscles, while EMG improved local blood flow; after training, the cross-sectional area of ​​the isococcal muscle increased by 28%, and the overall support of the pelvic floor was significantly enhanced; after treatment, the dynamic vaginal pressure increased from 60cmH2O to 95cmH2O, and the improvement rate of pelvic organ prolapse was 82%.

[0015] Furthermore, a pulsed negative pressure suction stimulation technique for Skien's glands was proposed: negative pressure intensity of -40 to -60 kPa, pulse frequency of 5-8 Hz, and duration of 10 minutes were used for treatment, three times a week for four consecutive weeks. The negative pressure pulses promoted angiogenesis around the gland, improving local ischemia; after treatment, vaginal lubrication improved from 3.2 points (VAS score) to 7.8 points, and the incidence of dyspareunia decreased by 67%; the non-invasive procedure avoided mucosal damage, significantly improving patient compliance.

[0016] Furthermore, an integrated approach combining electrostimulation biofeedback and Kegel exercises was developed for urogenital diaphragm repair: Electrostimulation biofeedback training was performed by placing electrodes on both sides of the urethral orifice (frequency 35Hz, pulse width 250μs), combined with three sets of Kegel exercises daily (20 rapid contractions + 10 slow contractions per set), and residual urine volume was monitored in real-time using ultrasound (target value <50ml). Electrostimulation improved muscle strength, while Kegel exercises enhanced endurance, synergistically improving the elasticity of the urogenital diaphragm; real-time ultrasound feedback of residual urine volume ensured the restoration of bladder emptying function (residual urine volume decreased by 62%); bladder compliance increased from 2.1ml / cmH2O to 4.8ml / cmH2O, and nocturia frequency decreased by 53%.

[0017] This invention provides a method and device for postpartum pelvic repair using integrated traditional Chinese and Western medicine, which has the following beneficial effects:

[0018] Based on MRI three-dimensional reconstruction technology to locate key target points in the pelvic floor (such as the coordinates of the origin and insertion points of the isococcal muscle at the S4-S5 sacral level), and combined with the TCM theory of "belt meridian circulation path", an innovative "three-line four-zone" manipulation scheme was proposed: lateral line: stimulating the obturator internus muscle (improving dyspareunia); central line: activating the levator ani complex (repairing prolapse); medial line: regulating the bulbospongiosus muscle (enhancing sensitivity). Clinical trials showed that for patients with grade II uterine prolapse, the POP-Q stage improvement rate reached 82% after 6 weeks of treatment, which was significantly better than the Kegel training group alone (41%).

[0019] Develop a "mechanical-electrophysiological dual-modal feedback system": Real-time monitoring of the elasticity of the urogenital diaphragm (normal value >25 mmHg) using pressure sensors; assessment of the coordination of the external anal sphincter using surface electromyography (normal antagonist ratio 1:1.2-1.5); automatic matching of personalized training programs: low-frequency vibration relaxation (20 Hz / 30 min) is used for hypertonic muscle groups (e.g., piriformis muscle hardness >40 kPa); high-intensity pulse stimulation (100 Hz / pulse train) is initiated for relaxed muscle groups (e.g., perineal body resting tension <15 mV).

[0020] Construct a comprehensive evaluation model comprising 4 dimensions and 12 indicators:

[0021] Evaluation Dimensions detection indicators Normal reference value Structural integrity Sacrococcygeal joint range of motion (°) ≤12° (supine position) Muscle strength level Type I muscle fiber sustained contraction time (s) ≥6s microcirculation status Skene's gland blood flow (ml / min) ≥8 Symptom improvement <![CDATA[Vaginal dynamic pressure (cmH2O)]]> ≥80

[0022] Innovative "painless" operation system: employing gradient pressure technology (initial pressure ≤0.5N, increasing by 10% every 3 days); a unique "breathing-contraction synchronous training method" (levator ani muscle contraction ≥20% of maximum voluntary contraction force during exhalation); special population adaptability verification: safety verification for breastfeeding women (pelvic floor muscle repair effectiveness rate still reaches 78% despite hormonal fluctuations); suitability for patients with keloid scarring (scar hyperplasia rate <3% 1 year post-operation).

[0023] The cost per treatment course is 83% lower than that of traditional surgery (approximately 3200 yuan per course); the recovery period is shortened (average 4.2 weeks vs. 8.7 weeks for traditional treatment); and the consumption of medical resources is reduced (the average number of visits per person is reduced from 12 to 4). Detailed Implementation

[0024] Example 1: Repair plan for vaginal laxity combined with urinary incontinence

[0025] The patient received treatment 42 days postpartum, complaining of vaginal laxity and urinary incontinence during coughing. The treatment involved the following steps: Glandular activation: The greater vestibular gland area was located and subjected to circular pressure at a 30Hz vibration frequency and 0.8kgf for 3 minutes, supplemented with 80Hz vibration to promote glandular secretion; Muscle training: An elastic band was used to apply 60% of the maximum contractile resistance, guiding the patient to perform alternating isometric and eccentric contractions, with biofeedback monitoring of electromyographic signals; Ligament adjustment: A combination of dynamic traction and static holding was used, with NIR monitoring maintaining the ligament elastic modulus at 1350MPa; Pressure sensors were placed in the perineal area, with a threshold of ≥20μV for peak contraction, and real-time feedback was used to adjust the contraction intensity; Bridge exercises and bulbospongiosus electromyography were combined, three times a week for eight weeks. After treatment, the vaginal dynamic pressure increased from 58cmH2O to 92cmH2O, and the frequency of urinary incontinence episodes decreased by 65%.

[0026] Example 2: Intervention for postoperative scar pain and dyspareunia following cesarean section

[0027] The patient had undergone a cesarean section one year prior, experiencing significant tenderness at the perineal episiotomy scar and vaginal pain during intercourse. The following treatment regimen was adopted: Targeted release: Ultrasound was used to locate adhesions beneath the scar, and circular pressure combined with vibration (60Hz frequency, 3mm amplitude) was applied to soften the scar, with a depth controlled to 2.5cm; Treatment of hypertonic muscles: Piriformis muscle was treated with hip flexion and external rotation resistance training (60% of maximum resistance), combined with end-expiratory contraction, twice a week, 12 sets each time; Microcirculation reconstruction: Skien's glands were treated with pulsed negative pressure (-50kPa, 8Hz) to promote local blood flow (blood flow increased 2.8 times after treatment); Neuromodulation: Pelvic floor muscle electrical stimulation (35Hz / 250μs) was performed simultaneously with coccyx muscle activation to improve local sensitivity. After 4 weeks of treatment, the VAS pain score decreased from 8 to 2, and sexual satisfaction significantly improved.

[0028] Example 3: Adjustment of pelvic floor muscle hypertonicity during lactation

[0029] Breastfeeding women often experience difficulty urinating due to persistent tension in the pelvic floor muscles caused by hormonal fluctuations. Treatment strategies are as follows:

[0030] Graded training: Grade I (muscle strength grade 3): 30% assisted isometric contraction, 10 seconds / repetition, 10 repetitions / set; Grade II (muscle strength grade 4): 50% resistance eccentric contraction, coordinated with breathing (exhalation during contraction, inhalation during relaxation); Dynamic traction: 30°-45° traction on the inguinal ligament at a frequency of 0.5Hz, avoiding overstretching; Thermotherapy: Local heat application (40℃, 10 minutes) after treatment to reduce muscle tone; Biofeedback optimization: Real-time adjustment of training intensity via sEMG to maintain electromyographic signals within the 15-25μV range. After 2 weeks of treatment, the resting tension of the pelvic floor muscles decreased from 18μV to 8μV, and urination returned to normal.

[0031] Example 4: Comprehensive intervention for severe uterine prolapse complicated with chronic pelvic pain

[0032] The patient presented with POP-Q stage III prolapse, accompanied by persistent lower abdominal pain. A multi-dimensional repair plan was adopted: Structural reconstruction: Shockwave therapy (0.2 mJ / mm²) was performed on the levator ani muscle tear area. 2 (Once a week); isocaudal muscle activation combined with bridging exercises to enhance pelvic floor support; functional training: urogenital diaphragm repair using electrical stimulation (35Hz frequency) combined with Kegel exercises, 2 sets daily; intravaginal pulsed negative pressure (-45kPa, 6Hz) to promote microcirculation. Pain management: Warm compresses (42℃, 8 minutes) combined with vibration massage (40Hz frequency) on the vestibular gland area. After 12 weeks of treatment, the prolapse degree decreased to grade I, the pain score decreased from 7 to 1, and normal life was restored.

[0033] Example 5: Rapid Recovery Program for Postpartum Urinary Retention

[0034] The patient had not urinated spontaneously for 48 hours postpartum, and ultrasound indicated a residual urine volume of 800 ml. Emergency treatment measures included: urethral activation: electrodes were placed on both sides of the urethral orifice, and 35Hz electrical stimulation was applied to induce detrusor muscle contraction. Sphincter coordination training: Kegel exercises combined with bulbocavernosus electromyography (EMG) (pulse width 200 μs) were used to enhance urethral closure function. Mechanical support: intermittent balloon compression (pressure 30 cmH2O, 10 times per minute) was used for urogenital diaphragm repair. Psychological intervention: Biofeedback display of EMG signals was used to enhance the patient's confidence in voluntary contraction. Spontaneous urination was achieved 3 hours after treatment, and the residual urine volume decreased to 50 ml, avoiding catheterization.
