Description

Technical Field

[0001] The present invention belongs to the technical field of transesophageal cardiac ultrasound diagnostic and therapeutic instruments, and particularly relates to a transesophageal cardiac ultrasound diagnostic and therapeutic instrument with a pacing function. Background Art

[0002] Transesophageal echocardiography is a method of examination that inserts an ultrasound probe into the esophagus and closely examines the deep structures of the heart from the back of the heart forward to obtain clearer and more accurate cardiac images. The advantage of this examination method is that it can avoid the interference of factors such as chest bones and pulmonary qi on the ultrasound image, thereby more clearly showing the structure and function of the heart. Through transesophageal echocardiography, doctors can more accurately diagnose heart diseases, such as left atrial appendage thrombus in patients with atrial fibrillation, heart valve diseases, congenital heart diseases, infective endocarditis, etc.

[0003] In the prior art, although the condition of the patient's heart can be detected and treated well through a transesophageal cardiac ultrasound diagnostic and therapeutic instrument, when using the transesophageal cardiac ultrasound diagnostic and therapeutic instrument in the prior art, it is often only possible to judge the spectral image of the patient's heart part through a display. The function of the transesophageal cardiac ultrasound diagnostic and therapeutic instrument for treating the patient's heart is relatively single. When the ultrasound probe is inserted into the patient's heart part for treatment, the pacing function for the patient's heart part is not high, resulting in poor timeliness of pacing and resuscitation for the patient's heart during treatment of the patient's heart part, reducing the treatment effect of the ultrasound therapeutic instrument on the patient's heart and being not conducive to the use by the staff. Therefore, we propose a transesophageal cardiac ultrasound diagnostic and therapeutic instrument with a pacing function. Summary of the Invention

[0004] In order to achieve the above object, the present invention adopts the following technical solutions: A transesophageal cardiac ultrasound diagnostic and therapeutic instrument with a pacing function, including an operation handle, one end of the operation handle is provided with an insertion tube, one end of the insertion tube is provided with an ultrasound probe, and an adjustment component is arranged inside the ultrasound probe; The adjustment component includes a rotating rod and a telescopic rod. A connecting rod is fixedly connected to the inner wall of the ultrasound probe. A threaded slider is slidably connected to the outer wall of the connecting rod. The outer wall of the threaded slider is rotatably connected to a rotating rod. One end of the rotating rod is rotatably connected to a telescopic rod telescopically connected to the outer wall of the connecting rod. A pacing component is arranged inside the ultrasound probe; The pacing component includes an electrode patch, an isolated pulse generator, and a FOGA control module. One end of the telescopic rod is fixedly connected to the electrode patch. A pressure sensor is arranged inside the electrode patch. An isolated pulse generator is arranged inside the electrode patch. A FOGA control module is arranged on one side of the isolated pulse generator.

[0005] In this technical solution, a pacing component is preset in the ultrasonic probe. After the ultrasonic probe extends into the patient's body through the patient's esophagus, in order to synchronously pace the patient's heart while detecting and treating the patient's heart condition and observing the treatment values and specific treatment conditions of the patient's heart, the servo motor can be turned on to drive the threaded slider to slide along the outer wall of the connecting rod through the rotation of the threaded rod. The sliding of the threaded slider drives the telescopic rod to expand and contract through the rotation of the rotating rod, and drives the electrode plate to extend from the surface of the ultrasonic probe, so that the electrode plate contacts the inner wall of the patient's esophagus; After the electrode plate contacts the inner wall of the patient's esophagus, through the control of the FOGA control module, the electrode plate and the ultrasonic probe are alternately operated. When pacing is required at the patient's heart, the FOGA control module drives the isolated pulse generator to operate, and generates an electric current at the patient's heart through the connection of the electrode plate to assist the patient's heart in starting to beat. At the same time, when the contact pressure between the electrode plate and the inner wall of the patient's esophagus exceeds the preset pressure value, the pressure sensor transmits a signal to the servo motor and drives the servo motor to stop driving, so that the electrode plate stops telescopic movement, achieving the effect of improving the contact between the electrode plate and the inner wall of the patient's esophagus.

[0006] Preferably, a servo motor is fixedly connected to the outer wall of the connecting rod, the output end of the servo motor is fixedly connected to a threaded rod rotatably connected to the outer wall of the connecting rod, and the pressure sensor is electrically connected to the servo motor.

[0012] Preferably, the overall material of the electrode plate is platinum-iridium alloy, and an electromagnetic shielding layer made of copper mesh is arranged between the ultrasonic probe and the electrode plate.

[0013] In this technical solution, since the overall material of the electrode plate is platinum-iridium alloy, and an electromagnetic shielding layer made of copper mesh is provided between the ultrasonic probe and the electrode plate, it plays a role in reducing the signal interference between the electrode plate and the ultrasonic probe.

[0014] Preferably, the FOGA control module controls the ultrasonic probe and the isolated pulse generator to perform alternating operation.

[0015] In this technical solution, by controlling the ultrasonic probe and the isolated pulse generator to perform alternating operation through the FOGA control module, it plays a role in alternately treating the patient with the detection function and the pacing function of the therapeutic instrument.

[0016] Preferably, one side of the operating handle is provided with an adapter block. The inner wall of the adapter block is rotatably connected with a conveying roller. The top of the adapter block is provided with a first nut. The inner wall of the first nut is rotatably connected with a first bolt. One end of the first bolt is rotatably connected with a clamping plate that is slidably connected to the outer wall of the adapter block. The outer wall of the adapter block is fixedly connected with a fixing plate located below the clamping plate. The rotation center of the conveying roller is fixedly connected with a ratchet disc through a rotating shaft. The outer wall of the adapter block is slidably connected with a connecting block. The outer wall of the connecting block is rotatably connected with a pawl located on the rotation track of the ratchet disc. The bottom of the pawl is fixedly connected with a spring that is rotatably connected to the outer wall of the connecting block.

[0017] In this technical solution, through the engagement and fixation between the ratchet disc and the pawl, it plays a role in improving the one-way rotation and conveying of the conveying roller, achieving the effect of maintaining the stability of the insertion tube without the need for the user to hold it, and reducing the loosening of the insertion tube.

[0018] Preferably, the insertion tube is wound on the conveying roller for feeding use. The bottom of the clamping plate is provided with anti-slip lines. The top of the fixing plate is provided with anti-slip lines. The cross-section of the connection part between the clamping plate and the fixing plate and the adapter block is U-shaped.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: A pacing component is preset in the ultrasonic probe. After the ultrasonic probe extends into the patient's body through the patient's esophagus, in order to synchronously pace the patient's heart while detecting and treating the patient's heart state, when observing the treatment value and specific treatment situation of the patient's heart, the servo motor can be turned on to drive the threaded slider to slide along the outer wall of the connecting rod through the rotation of the threaded rod. The sliding of the threaded slider drives the telescopic rod to perform telescopic movement through the rotation of the rotating rod, and drives the electrode plate to extend out from the surface of the ultrasonic probe, so that the electrode plate contacts the inner wall of the patient's esophagus; After the electrode plate contacts the inner wall of the patient's esophagus, through the control of the FOGA control module, the electrode plate and the ultrasonic probe are alternately operated. When it is necessary to pace the patient's heart, the FOGA control module drives the isolated pulse generator to operate, and generates an electric current at the patient's heart through the connection of the electrode plate to assist the patient's heart to perform a jumping movement. At the same time, when the contact pressure between the electrode plate and the inner wall of the patient's esophagus exceeds the preset pressure value, the pressure sensor transmits a signal to the servo motor and drives the servo motor to stop driving, so that the electrode plate stops telescopic movement, achieving the effect of improving the contact between the electrode plate and the inner wall of the patient's esophagus.
