An ultrasonic probe rotating device and its use method and application

Abstract

The invention discloses an ultrasonic probe rotating device and its use method and application. It mainly includes a rotating magnet, a rotating motor and a rotating guide component. The rotating magnet is connected to the output shaft of the rotating motor. The side surface of the rotating magnet is tangent to the outer circumference of the rotating guide member. The technical scheme of the present invention drives the rotating motor to drive the magnet to rotate the rotating guiding part and control it in time at the same time. At the same time, the rotating guiding part compensates the undesired displacement of the asymmetric structure ultrasonic probe, avoiding the loss of control of the motor or the undesired displacement causing the target organ deformation, equipment damage, and even accidental injury to the recipient, improving system security.

Description

technical field [0001] The invention relates to the field of medical equipment, more specifically, to a medical equipment for prostate surgery. Background technique [0002] The prostate is a very rare gonadal gland with both internal and external secretion functions, such as a chestnut, with the bottom facing up and attached to the bladder, the tip facing down, touching the urogenital diaphragm, the pubic symphysis on the front, and the rectum on the back. The urethra passes through the middle of the prostate gland and guards the upper opening of the urethra. Therefore, if the prostate is diseased, urination will be affected first. When there are lesions in the prostate, one method is "digital rectal examination", which involves feeling the back of the prostate and making judgments based on the doctor's experience. The other method is to perform a prostate biopsy, that is, to take a small part of the prostate tissue as a sample. Pathologists or professional doctors examine...

[0006] 2. In the prior art, in order to realize the transmission structure of the rotation of the ultrasonic probe, the gear connection mode is mostly used, and the output shaft of the motor is driven to drive the rotation of the ultrasonic probe. Additional structures and spaces are required for fixing the gears, which occupy a large operating space. Increased mechanical complexity

At the same time, there is a certain error in the gear transmission, which affects the accuracy of the equipment

[0007] 3. Among the intracavity ultrasonic probes currently used, there are many asymmetrical ultrasonic probes (that is, the central axis of the front of the probe does not coincide with the central axis of the handle, for example, the front end of the probe is thin and the end of the handle is thick); The probe device mostly adopts a symmetrical structure and a uniform thickness design, and it rotates around the central axis of the clamped part (ultrasound probe handle) by default, rather than around the central axis of the target rotating part (front part of the ultrasonic probe) in the cavity. Directly cause the ultrasonic probe to rotate eccentrically in the human body, which may cause the deformation of the target scanning organ, reduce the imaging accuracy, and even damage the protective cover of the ultrasonic probe, causing harm to the patient and causing medical accidents
