In-vitro soft tissue positioning assisting device applied to C-shaped arm and positioning method

Abstract

The invention discloses an in-vitro soft tissue positioning assisting device applied to a C-shaped arm and a positioning method.The in-vitro soft tissue positioning assisting device comprises a cover body, four fixing claw mechanisms are arranged at the top of the cover body and used for installing the cover body on a receiver of the C-shaped arm, and two rotating adjusting mechanisms and two developing auxiliary positioning mechanisms are arranged in the cover body in a mirror image mode; the rotary adjusting mechanism and the developing auxiliary positioning mechanisms located on the same side of the horizontal partition plate are in transmission connection through a belt, each developing auxiliary positioning mechanism comprises a transmission shaft, a cantilever is fixedly connected to each transmission shaft, Mark mark points are movably arranged on the cantilevers, developing adjusting mechanisms corresponding to the Mark mark points are arranged on the cover body, and the developing adjusting mechanisms are in transmission connection with the developing auxiliary positioning mechanisms. The developing adjusting mechanism is used for adjusting the Mark mark point to move in the cantilever direction, and the rotating adjusting mechanism is used for adjusting the cantilever to rotate horizontally with the transmission shaft as the axis. The device has the advantages of being safe and convenient to operate, capable of reducing ray irradiation receiving time and accurate and lasting in positioning.

Description

technical field [0001] The invention relates to the technical field of clinical imaging, in particular to a device and a positioning method for externally assisting soft tissue positioning on a C-shaped arm. Background technique [0002] The C-arm is the C-arm X-ray machine, which is a common equipment for clinical operations in hospitals. It is a "C"-shaped arm-shaped frame structure, and the upper arm of the C-arm is equipped with an X-ray receiver. The receiver simultaneously It has the function of image enhancement. An X-ray generator is installed on the lower arm of the C-shaped arm. After receiving the X-ray signal, the upper arm of the C-shaped arm outputs the image through the image intensifier. The video signal can be displayed on the monitor in real time so that the doctor can see the patient's condition. Image, the C-arm X-ray machine can actually observe the patient instantaneously or dynamically. Through the judgment and observation of the image by the doctor, t...

Problems solved by technology

[0010] The present invention aims at the problem that the C-arm X-ray machine in the background technology lacks the function of auxiliary positioning, so that the operator’s operation is cumbersome due to the manual use of contrast agents or non-special developing objects to achieve indirect development, and provides a C-arm X-ray machine.
