3 Terms and definitions
The following terms and definitions apply to this document.
3.1
In ultrasound diagnosis and treatment operations, it is used in conjunction with intracavity or extracorporeal ultrasound probes for puncture needles, drainage tubes, treatment or drug delivery devices
Such as the guiding and fixing device of the puncture instrument.
3.2
In-planepuncture
During the puncture process, the puncture instrument and the sound beam are in the same plane.
3.3
Out-planepuncture
During the puncture process, the puncture instrument and the sound beam are not in the same plane.
4 Structure type and naming
The ultrasonic probe puncture frame is mainly composed of a frame body used to fix the probe and a needle groove channel used to fix and guide the puncture instrument.
According to the positional relationship between the puncture path and the plane of the sound beam, the ultrasonic probe puncture frame is divided into an in-plane puncture frame and an out-of-plane puncture frame.
According to the matched ultrasound probes, the ultrasound probe puncture rack is divided into an extracorporeal ultrasound probe puncture rack and an intracavity ultrasound probe puncture rack.
The ultrasonic probe puncture frame is divided into reusable puncture frame and single-use puncture frame according to different uses.
Several typical structures of the ultrasound probe puncture frame and the names and terms of each part, see Appendix A.

The manufacturer expects that the distance from the point on the straight line of the image displayed on the applicable scope to the puncture guide line should not exceed the number specified by the puncture frame manufacturer.
Value, but the maximum distance must not exceed 5mm; when the detection depth is greater than 4cm, the puncture needle will display on the expected scope of application.
The distance between the point on the line where the image is located and the puncture guide line should not exceed the value specified by the puncture frame manufacturer, but the maximum distance should not exceed the value specified by the puncture frame manufacturer.
Over 10mm.
5.3.3 For ultrasound imaging equipment that only displays the puncture guide area, when the detection depth is less than or equal to 4 cm, the puncture needle is
The frame manufacturer expects that the distance from the point on the straight line where the image displayed on the scope of application is to the center line of the puncture guide area should not exceed the puncture frame system.
The value specified by the manufacturer, but the maximum distance must not exceed 5mm; when the detection depth is greater than 4cm, the puncture needle is expected to be suitable
The distance from the point on the line where the image displayed on the range is to the center line of the puncture guide area should not exceed the value specified by the puncture frame manufacturer.
However, the maximum distance must not exceed 10 mm; the image displayed on the ultrasound imaging device by the puncture needle must not exceed the puncture guide area.
range.
5.3.4 For situations where there is no guide line or no guide line is used, the requirements of 5.3.1 shall be met.
