Probe flexible connecting device for B-ultrasonic robot

Abstract

The invention discloses a probe flexible connecting device for a B-ultrasonic robot. The probe flexible connecting device comprises a flexible connecting part and a clamping base; one end of the flexible connecting part is fixed to the tail end of a mechanical arm of an ultrasonic detection robot; the other end of the flexible connecting part is fixed to one end of the clamping base; the clampingbase is of a door-shaped structure; an ultrasonic probe and a clamp holder for clamping the ultrasonic probe are arranged at the other end of the clamping base; one end of the ultrasonic probe is arranged in the clamping base; a sound transmission device is arranged at the other end of the ultrasonic probe; the clamp holder comprises a U-shaped clamping part and a hoop; and the U-shaped clamping part is clamped on the clamping base and locked through the hoop. The probe flexible connecting device for the B-ultrasonic robot provided by the invention has axial and radial flexibility, can realizeflexible contact between the ultrasonic probe and human skin, has friendly design appearance and experience process, realizes passive flexibility, and is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a probe flexible connection device for a B-ultrasound robot. Background technique [0002] B-ultrasound detection technology in the medical field, as a detection method without radiation damage, has become an important medical detection method due to its rapid diagnosis, equipment portability and detection flexibility. The traditional hand-held probe detection method will cause repetitive labor injuries to doctors, and the imaging quality depends on the doctor's work experience and operating techniques. It is difficult for doctors and patients to break through the limitation of space. Using B-ultrasound robots instead of manual detection can effectively avoid these questions. [0003] In the detection process using a B-ultrasound robot, the contact process between the ultrasonic probe and the patient's body is particularly important: if the contact force is insufficient, the imag...

Problems solved by technology

The commonly used solution is to use the force control algorithm to control the contact force in real time to keep it in a safe range, but this method is difficult to control, and at the same time, the potential failure factor of the electronic system or software is a major safety hazard; another solution is to design The flexible contact device realizes flexible contact during the detection process and provides mechanical safety protection functions, but most of the existing devices have complex structures and are difficult for doctors to use
