A pressurization system applied to an ultrasonic scanning device

Abstract

The invention relates to the technical field of ultrasonic scanning, and discloses a pressurization system applied to an ultrasonic scanning device, including a pulley block, a steel wire rope wound around the pulley block, a workbench connected with the steel wire rope for installing an ultrasonic probe assembly, and a steel wire rope The connected counterweight assembly, the steel wire rope includes a first rope part and a second rope part respectively located on both sides of the pulley block, the workbench is connected with the first rope part, and the counterweight assembly is connected with the second rope part, and the counterweight assembly includes a common counterweight The common weight is connected with the second rope portion, the pressurized weight is movably connected with the common weight, and the pressurized weight is also connected with a lifting components. The present invention is easy to use, has good adaptability, can adjust the pressurized state following breathing, ensures that the pressure on the human body is always consistent during exhalation and inhalation, reduces the feeling of oppression and chest tightness, and improves the satisfaction of the user's inspection experience.

Description

technical field [0001] The invention relates to the technical field of ultrasonic scanning, in particular to a pressurization system applied to an ultrasonic scanning device. Background technique [0002] Ultrasound imaging has important clinical applications due to its advantages of non-invasive, real-time, strong repeatability, and low cost. Existing ultrasound examinations (such as breast, abdomen, etc.) are generally manual scanning. Doctors use hand-held scanning devices to press and move on the human body for scanning, which makes the inspection effect greatly dependent on the doctor's operation. Inconsistent or missed diagnosis due to differences in doctor's operating techniques and coverage areas. In order to solve this problem, in breast ultrasound examination, a whole breast ultrasound system is proposed. This system uses a mechanical scanning device to scan the entire breast of the subject, which solves the requirements for doctors' techniques to a certain extent...

Problems solved by technology

During the operation, the greater the pressure of the ultrasonic probe on the subject, the better the contact with the skin, and the better the image effect. In addition, when the equipment is pressurized, a fixed initial pressure value is generally set, as disclosed The patent document No. CN109316207A discloses "a breast ultrasound scanning system and method". Once the probe is in place and the detection starts, the initial pressure value remains unchanged until the end of the detection. The initial pressure value is set in consideration of human Breathing is accompanied by the contraction and expansion of the thoracic cavity. The initial pressure value should be as large as possible to ensure sufficient pressure during thoracic cavity contraction and ensure image quality. The blockage acts on the subject together with the initial pressure value, resulting in greater pressure on the human body. Therefore, at this time, the human body's oppressive feeling and chest tightness are particularly serious. Although some equipment is equipped with a pressure value adjustment device, However, each patient’s somatosensory is different, and the doctor needs to make adjustments according to the actual situation. The process is cumbersome, which not only requires a lot of effort, but also tends to slow down the progress of the examination, and even cause false and missed examinations.
