Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and specifically relates to a guiding device for puncture biopsy of a biplane ultrasound probe. Background Technique

[0002] In medical diagnosis, puncture biopsy is a commonly used diagnostic method. It extracts samples from suspected diseased tissues by using a fine needle for pathological examination and confirmation. Traditional puncture biopsy methods often rely on doctors' experience and manual operations, which may lead to inaccurate positioning of the biopsy needle, increasing the difficulty of the operation and the pain of the patient. At the same time, it may also reduce the biopsy success rate and the representativeness of the sample. With the development of medical technology, ultrasound-guided puncture biopsy technology has gradually become the mainstream. It uses an ultrasound probe to real-time monitor the position and path of the puncture needle, greatly improving the accuracy and safety of the puncture. However, traditional ultrasound-guided devices usually only equipped with a single-plane ultrasound probe, which may limit the doctor's vision in some cases, especially in puncture biopsy of deep tissues. The single-plane visual information may not be sufficient to provide enough guidance. While the biplane ultrasound probe can provide images of two different cross-sections, enabling doctors to observe the relationship between the puncture needle and the diseased tissue from multiple angles, greatly expanding the doctor's vision. Through the biplane ultrasound images, doctors can more accurately locate the lesion, plan the puncture path, thereby improving the biopsy success rate, reducing the harm to the patient, and obtaining more reliable diagnostic results.

[0003] At present, most of the guiding devices for puncture biopsy of biplane ultrasound probes on the market cannot replace the ultrasound probe, resulting in a small application range of the device. Therefore, different devices are needed in different surgeries, with a high cost. Thus, we propose a guiding device for puncture biopsy of a biplane ultrasound probe. Content of the Utility Model

Through the images of two different sections provided by the first ultrasonic probe 201, doctors can observe the relationship between the puncture needle and the lesion tissue from multiple angles, greatly expanding the doctor's vision and providing sufficient guidance to the doctor. The doctor can more accurately locate the lesion position and surrounding structures according to the image analysis, and plan the puncture path based on the ultrasonic image, determine the puncture point and entry angle, and achieve the guidance for percutaneous biopsy;

[0032] When it is necessary to use the second ultrasonic probe 202 with an acoustic beam emitter 203 at the front end or other types of probes, only need to pull the handle 109 in the direction away from the mounting base 101 respectively. Drive the clamping block 107 to move into the inside of the chute 104 through the sliding rod 106 and release the clamping connection with the clamping groove 206, and compress the first spring 105. Then, remove the first ultrasonic probe 201 in the direction away from the mounting base 101. Subsequently, release the handle 109, so that the clamping block 107 moves into the inside of the fixing hole 103 under the action of the elastic force of the first spring 105. Then, align the jack 204 on the second ultrasonic probe 202 or other types of probes with the connector 102 on the mounting base 101, and insert the positioning rod 205 into the inside of the fixing hole 103. Make the end of the positioning rod 205 close to the fixing hole 103 squeeze the inclined surface of the clamping block 107. Through the inclined surface, the clamping block 107 moves into the inside of the chute 104 and compresses the first spring 105. When the positioning rod 205 is clamped with the fixing hole 103, the jack 204 is clamped with the connector 102, and the clamping groove 206 moves between the two clamping blocks 107. Subsequently, the clamping block 107 will be clamped with the clamping groove 206 under the action of the elastic force of the first spring 105, completing the replacement of the probe.
