Three-dimensional (3D) mechanical probe

Abstract

The invention discloses a three-dimensional (3D) mechanical probe, which comprises a sound window, a base, a restraining body and an elastic sealing ring, wherein the sound window and the base are fixedly connected and form a sealed space, the sound window is provided with a first matching wall, the base is provided with a second matching wall, the first matching wall is sheathed with the second matching wall, the sealing ring is arranged between the first matching wall and the second matching wall and is tightly pressed to deform, and the restraining body limits the deformation of the sound window. Through the sealing ring with the compression deformation quantity between the first matching wall and the second matching wall, the sealing between the sound window and the base can be effectively ensued, the coupling liquid seepage is prevented, through the arrangement of the restraining body, the sound window is prevented from deforming through being expanded by the sealing ring, the sufficient deformation quality of the sealing ring is ensued, and the sealing performance between the base and the sound window is further ensured.

Description

technical field [0001] The invention relates to a 3D mechanical probe for 3D ultrasound imaging. Background technique [0002] The ultrasonic probe with three-dimensional imaging function is called a 3D mechanical probe, which generally has a stepping motor as a driving power source inside, and the stepping motor drives the sound head to swing within a certain angle through the transmission system under signal control. At each swing angle, the 3D mechanical probe can emit ultrasonic waves like a traditional probe and receive echoes with human tissue information, so that human tissue can be imaged at every angle within the swing range, without the need for doctors to move the probe Sliding or swinging on the surface of the human body. [0003] Such as figure 1 and figure 2 As shown, the existing 3D mechanical probe includes a base 1 and an acoustic window 12, the base 1 and the acoustic window 12 are connected to form a closed space 13, the acoustic head 10 is fixedly con...

AI Technical Summary

Problems solved by technology

Commonly used materials for the acoustic window 12 are TPX (poly-4-methylpentene-1), PP (polypropylene), LDPE (low-density polyethylene), etc. These materials have low surface energy and are difficult to bond reliably. The viscose is in contact with the coupling liquid for a long time. When the acoustic head 10 swings, the coupling liquid in the closed space 13 has fluctuating pressure and acts on the bonding surface. Peeling, cannot reliably ensure the connection and sealing between the acoustic window 12 and the base 1
