Description

TECHNICAL FIELD

BACKGROUND

[0002] Female pelvic floor dysfunction (Pelvic Floor Dysfunction, PFD) is a group of diseases caused by defects or degradation of pelvic support structure, injury and dysfunction, its symptoms include pelvic organ prolapse, urinary incontinence, fecal incontinence and constipation, dysuria, chronic pelvic pain, etc., seriously affect the physical and mental health and quality of life of patients. In recent years, the incidence of pelvic floor dysfunction is gradually increasing, and has become one of the most common chronic diseases of middle-aged women in China, so it is of great significance to detect and treat the pelvic floor function of such women.

[0003] At present, the detection probe for female pelvic floor dysfunction generally has defects, for example: Chinese patent CN218220224U discloses an electromyography acquisition and pelvic ultrasound combined examination system, which relates to a pelvic ultrasound module and an electromyography acquisition module. The pelvic ultrasound module can realize the acquisition of the ultrasonic image of the examination site, and the electromyography acquisition module can realize the acquisition of the electromyography signal of the examination site, so that the comprehensive examination of the detection site can be quickly completed according to the obtained pelvic ultrasound image and electromyography acquisition result of the detection site, and more accurate examination results can be obtained. However, when acquiring electromyography signal, the detection system still uses single-channel electromyography acquisition, which can only qualitatively reflect the pelvic muscle strength state, and cannot quantitatively represent the state of different muscle groups or quantitatively distinguish the state of different muscles at different positions, so that the measurement result of pelvic electromyography data is not accurate. Even if combined with ultrasonic image, the overall state of pelvic function cannot be accurately and intuitively reflected, which is not conducive to the precise diagnosis and treatment of clinicians. In addition, Chinese patent CN116392129A also discloses a modular device for pelvic muscle state evaluation and a method for using the same. The device is composed of a probe body, an electrode ring and an air bag ring. The surface of the main body of the probe body is provided with a plurality of detachable air bag rings or electrode rings from top to bottom, which can meet the use of different scenes. Through the setting of the air bag ring, the pelvic muscle strength can be evaluated by pressure detection, and the elasticity and inner diameter of the vagina can be evaluated by pressure detection. Through the setting of the electrode ring, the reaction speed and muscle stability of the pelvic muscle can be evaluated by electromyography detection, and the pelvic muscle can be comprehensively scored by combining the pressure detection result and the electromyography detection result. However, the structure of the device is relatively complex, and pressure detection or electromyography detection needs to be installed with air bag ring or electrode ring respectively before it can be carried out, which is not conducive to clinical use.

[0004] In summary, the existing detection probe only has the detection functions of combining myoelectricity and muscle strength, and combining myoelectricity and ultrasound, and the myoelectricity detection can only roughly realize the measurement of average myoelectricity, so that the measurement is not accurate and the repeatability is poor, or the structure is complex, and the visual image cannot be provided at the same time of multi-channel myoelectricity detection to assist the clinician to obtain more intuitive pelvic floor function state data, therefore, in order to assist in improving the accuracy of the existing detection and treatment of female pelvic floor dysfunction, it is necessary to provide a portable multifunctional detection probe integrating ultrasound, endoscope and myoelectricity precise detection.
