Description

Ultrasonic probe convenient to puncture

Technical Field

The utility model relates to a medical ultrasonic testing equipment field, concretely relates to ultrasonic probe convenient to puncture.

Background

With the rapid development of electronic technology, the integration level of ultrasonic imaging hardware is higher and higher, and the size of a hardware board card for ultrasonic imaging is smaller and smaller, so that front-end hardware can be directly placed in a probe handle, even the whole imaging hardware including signal processing and image processing is built in the handle, and data is sent to a computer or a mobile phone and other equipment through a USB interface or a wireless WIFI module for further post-processing and display. This is called hand-held ultrasound (hand-held ultrasound) in common, and this type of ultrasound is also commonly called mobile phone ultrasound because most of these devices can be combined with the existing smart phones.

The existing structure of the handheld ultrasound generally comprises at least basic components of a sound head, a hardware circuit board, a sound head shell and a handle. The sound head is connected with the sound head shell through glue (the sound head is fixed and the sealing is ensured at the same time), and the sound head is connected with the hardware circuit board through a connector assembly (the sound head is connected with a socket on the circuit board through a plug on the flexible FPC for mounting). If the probe is connected with a host such as a mobile phone or a computer in a wired manner, the probe is generally connected with the host through a USB interface and a USB cable. If connect through wireless mode, the handle is inside still to contain the rechargeable battery of a pair of hardware circuit board power supply at least, and the circuit is generally through WIFI wireless connection with the connection of host computer. The design of the probe is generally a centrally symmetrical structural design.

Compared with the common traditional probe, at least one hardware circuit board is contained inside, so that the size of the handle is increased, including the width and the length. For probes with larger size relative to the sound head, such as a common abdominal probe or a superficial probe for small organ examination, the size increase of the handle can be ignored, but for some special probes, such as a small linear array of small convex and blood vessel puncture, the size of the sound head is only 2cm, but the general width of the circuit board is more than 4cm, and the thickness of the handle is added, so that the sound head is mostly blocked by the handle if the traditional centered symmetrical structural design is still adopted.

The puncture can be divided into in-plane puncture and out-of-plane puncture, the so-called plane is the plane of ultrasonic imaging, if the puncture needle is always visible in the puncture plane in the puncture process, the in-plane puncture is performed, and at this time, the puncture needle needs to enter the ultrasonic imaging plane from the side surface of the probe. While out-of-plane puncture tends to insert the needle from the front of the probe, and only a bright spot display (corresponding to the tip or cross-section of the needle) of one needle can be seen in the ultrasound imaging plane. In actual puncture, because the length of the puncture needle is limited, in order to observe the motion track of the puncture needle in real time in an ultrasonic image, the puncture needle needs to be close to the probe as much as possible, so that the puncture needle can enter the field of view of ultrasonic imaging quickly after entering tissues, and the puncture risk is reduced.

Taking the small linear array probe as an example, the small linear array probe is used for in-plane puncture, the raised handle blocks the sight line of the sound head, the puncture needle can only be inserted by being tightly attached to the raised handle, and the puncture needle can reach the imaging plane after a long distance under the skin, so that the clinical risk of mistakenly puncturing dangerous parts in the period is increased on one hand, and on the other hand, the short puncture needle can possibly not be punctured in place.
