Embodiment Construction

[0028] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only the technical solutions of the present invention. Some, but not all, embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0029] Such as Figure 1 to Figure 3 As shown, this embodiment provides a positioning device for assisting C-arm fluoroscopy, which is used for non-isocentric C-arm 1. The C-arm 1 is provided with at least two fluoroscopy positions. Since the C-arm 1 itself has a rotating structure, it can Rotate from one perspective position to another around its rot...

Abstract

The invention discloses a positioning device for assisting C-arm perspective, a C-arm X-ray machine and a positioning method, and relates to the technical field of medical devices. Wherein the positioning device includes a first laser assembly and a second laser assembly, the laser beam emitted by the first laser assembly and the laser beam emitted by the second laser assembly intersect at the target point, wherein the target point is located: when the C-arm is in the normal position The intersection area of ​​the X-ray beam and the X-ray beam when the C-arm is in the lateral position. The present invention locates the target point through the first laser component and the second laser component, and then places the region of interest at the target point. Through one positioning, the perspective imaging of the region of interest in two directions can be realized, thereby reducing the The number of adjustments in the area improves the work efficiency, reduces the radiation dose of X-rays, and reduces the radiation damage of X-rays to patients.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a positioning device for assisting C-arm fluoroscopy, a C-arm X-ray machine and a positioning method. Background technique [0002] In orthopedic surgery, the C-arm machine is often used to perform fluoroscopy on the patient's lesion. Because the fluoroscopy image has important reference value for the doctor's diagnosis, before the operation, the medical staff will generally perform multi-angle fluoroscopy on the patient's lesion, including not only frontal fluoroscopy and lateral fluoroscopy, but also oblique perspective . However, for the existing mobile C-arm, it is very inconvenient to switch between the front and side positions. For example, after the doctor takes the front position image, when adjusting the C-arm to the side position, he often faces the region of interest (such as a lesion) ) is not in the imaging area of ​​the plate. Therefore, doctors need to c...
