An auxiliary c-arm machine precision shooting device

Abstract

The invention discloses an auxiliary C-arm machine precision shooting device, which relates to the field of medical equipment. An auxiliary C-arm machine precision shooting device, including a telescopic adjustable hoop, a plurality of mounting seats are arranged on the hoop, the mounting seats are detachably and fixedly connected to the hoop, and a battery is arranged in the mounting seat Frame, the side of the battery frame is provided with a laser lamp placement groove, a laser lamp is arranged in the laser lamp placement groove, and an emission hole is arranged on the mounting base, and the emission hole communicates with the laser lamp placement groove, and the laser lamp is Cross laser light, the emission hole and the laser light are arranged eccentrically. The beneficial effects of the present invention are: it can effectively and continuously fix the laser lamp, avoid the laser beam angle change caused by the displacement of the laser lamp, and facilitate the replacement of the lost laser lamp, the structure is simple, and it is easy to install on different types of C-arm machines; the manufacturing cost is low, It is cost-effective and can be promoted and applied nationwide.

Description

technical field [0001] The invention mainly relates to the field of medical equipment, in particular to an auxiliary C-arm machine precise shooting device. Background technique [0002] C-arm X-ray machine (C-arm machine for short) is a mobile X-ray machine integrating light, machine and image processing technology, and is one of the most commonly used surgical aids in orthopedic surgery. When shooting, place the image intensifier and tube of the C-arm on both sides of the target area, adjust the appropriate angle, and shoot to obtain images. However, to obtain a satisfactory image, the image intensifier must be precisely centered on the target area, and the perspective angle must be adjusted. [0003] At present, the C-arm machine used in clinical practice has a small fluoroscopy range and basically does not have a pre-alignment device. Before fluoroscopy, it is estimated by visual inspection whether the C-arm can effectively capture the image of the target area. In real...
