Description

Technical Field

[0001] This invention relates to the field of medical device technology, and specifically to an ultrasonic transducer connector. Background Technology

[0002] Ultrasound ablation is a medical technique commonly used to treat tumors or other abnormal tissues. This process uses ultrasound waves to generate heat, destroying or ablating the tissue. Ultrasound ablation can be applied to multiple medical areas, including the liver, thyroid, breast, and prostate. In ultrasound ablation, doctors use an ultrasound probe to deliver high-frequency sound waves directly to the target tissue area. The heat generated by these sound waves causes the tissue to heat up, ultimately leading to cell apoptosis or necrosis. This process helps treat some tumors, masses, or other abnormal tissues without the need for traditional surgical removal. Ultrasound ablation is often considered a minimally invasive treatment because it can be performed through small incisions on the body surface or via a laparoscopy, reducing invasiveness for the patient.

[0003] In the ultrasonic transducer module, the signal detected by the probe needs to be transmitted to the external receiving device. Therefore, a connector is needed to connect the probe to the external device. The purpose is to complete the signal transmission by connecting the two PCB circuit boards.

[0045] Furthermore, since the first PCB board 5 and the second PCB board 6 cannot directly contact each other for electrical connection, a PCB connector 8 is provided in the socket 7. The PCB connector 8 is provided with a mating groove that matches the size of the second PCB board 6. The second PCB board 6 achieves electrical connection with the first PCB board 5 by inserting into the mating groove.

The first PCB board 5 is fixedly connected to the PCB connector 8, and the connection between the first PCB board 5 and the second PCB board 6 is realized by connecting the second PCB board 6 to the mating groove.

[0047] To further explain the internal structure of the ultrasonic transducer connector, please refer to... Figure 5 and Figure 6 Both the left connector 1 and the right outer shell 2 can be divided into upper and lower halves, which are connected together by an interference fit of a pin 91 and a hole 92. The right outer shell 2 is provided with a pin 93 inside, and the second PCB board 6 is provided with a positioning hole 61. The pin 93 cooperates with the positioning hole 61 to fix the second PCB board 6. This structure is simple, reliable and low cost. In this embodiment, the pin 93 is staggered, which can limit the second PCB board 6 in different directions. During use, it can cope with various flipping usage scenarios of the ultrasonic transducer connector, so that the second PCB board 6 will not loosen or shake, and the reliability is good. In addition, from the perspective of easy installation and manufacturing and cost reduction, the left connector 1 is composed of two halves and is locked by screws. The screw holes of the connecting screws are set on the guide post 11, making full use of the internal space of the left connector 1.

[0048] The usage process of this invention is as follows: a locking mechanism is formed by the elastic sheet 3, the first locking strip 41 and the first positioning groove 71. The first locking strip 41 and the first positioning groove 71 are automatically matched and locked during the docking process of the left connector 1 and the right outer shell 2. When connecting, the left connector 1 and the right outer shell 2 can be docked directly. When unlocking, the left connector 1 and the right outer shell 2 can be pulled apart by lightly pressing the elastic sheet 3.
