Embodiment Construction

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] The core of the present invention is to provide a 3D mechanical probe, the 3D mechanical probe can connect the acoustic window and the base with a buckle structure, and can make the acoustic window and the base move relative to each other at the same time, so that no additional The volume compensation device can also compensate the volume change caused by thermal expansion and contraction of the couplant.

[0032] In order to enable those skilled in the...

Abstract

The invention discloses a 3D mechanical probe. The 3D mechanical probe comprises a base, an acoustic window which is arranged on the base and is connected with the base in a matching manner, and a buckling structure which is used for clamping the acoustic window and the base and can enable the acoustic window and the base to move relatively. The 3D mechanical probe has the advantages that under the connection effect of the buckling structure, when the temperature of the probe rises or falls, namely, the coupling liquid in the cavity is heated to expand or shrink, the acoustic window can move upwards or downwards relative to the base, the problem of excessive internal positive pressure or negative pressure cannot be generated, therefore, the use of a volume compensation device can be avoided while the influence on the sealing performance due to the great change of the internal pressure is avoided, so that the interface design can be reduced, and the problems of coupling liquid leakage and difficulty in removing bubbles in the cavity due to the additional arrangement of the volume compensation device are solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a 3D mechanical probe. Background technique [0002] Ultrasound probes with three-dimensional imaging capabilities are called 3D mechanical probes. The 3D mechanical probe drives the ultrasonic probe to swing within a certain angle through the motor and transmission system inside the probe. During the swinging process, the ultrasonic probe emits ultrasonic pulses at a certain frequency and receives echoes. The echo carries the information of the human tissue penetrated by the ultrasonic wave, and the image of the human body can be generated by processing the echo signal, and finally the image information is combined with the angle information to finally generate a three-dimensional image. [0003] The combination of the acoustic window and the base is a common combination of the existing 3D mechanical probes. The acoustic window and the base together enclose a closed cav...
