Embodiment 1

[0020] Such as figure 1 As shown, it is a partial screenshot of the ultrasonic sensor and insertion tube of the laparoscopic probe, 1 is the ultrasonic sensor shell area, and 2 is the insertion tube area. When working, 1 and 2 are inserted into the abdominal cavity through the small hole opened in the abdomen of the human body for exploration. It can be seen that the working area of ​​the ultrasonic sensor is not located at the geometric center of 1, and it is difficult for doctors to accurately judge the sound field focal plane and sound field boundary of the ultrasonic sensor through the external display.

[0021] A position calibration line is printed axially on the outer surface of the laparoscopic ultrasound probe sensor housing, and the position calibration line may include at least one or a combination of the following:

[0022] Projection point geometric symmetry center projection point calibration line 31 , sound field focal plane projection line 32 , and equal divis...

Embodiment 2

[0031] An embodiment of the present invention also provides a probe, the probe includes the sensor as described in the first embodiment, the sensor is described in detail in the first embodiment, and will not be repeated here.

Abstract

The invention provides a laparoscope ultrasonic probe sensor for improving the physical positioning accuracy. The laparoscope ultrasonic probe sensor comprises an outer casing and an internal main body structure of the outer casing, wherein the outer surface of the outer casing of the sensor is printed with a position calibration line in the axial direction, and the position calibration line at least comprises the following one position calibration line or the combination of several position calibration lines from a projection point geometric symmetry center projection point calibration line, a sound field focusing plane projection line and a uniform scale calibration line. The invention also provides a corresponding probe. When the technical scheme of the invention is adopted, the problem that the detecting region of the existing laparoscope ultrasonic probe cannot be accurately positioned in a human body is solved.

Description

technical field [0001] The invention relates to the field of probes, in particular to a laparoscopic ultrasonic probe sensor and a probe for improving the accuracy of physical positioning. Background technique [0002] The ultrasonic sensor of the external ultrasonic probe is generally located in the geometric center of the shell, and the user directly touches the probe, so that the probe can be conveniently placed in the central working area of ​​the sensor to obtain a good field of view and acoustic image, such as figure 2 As shown, it is a schematic diagram of a conventional body surface probe. The working area of ​​the ultrasonic sensor is located at the geometric center of the probe shell. The operator can look directly at the sensor and conveniently place the sound field focus plane of the ultrasonic sensor on the target detection area. [0003] The acoustic sensor of the laparoscopic ultrasound probe is generally not located at the symmetrical center of the shell, and...
