Device assisting C-arm machines with accurate shooting

Abstract

The invention discloses a device assisting C-arm machines with accurate shooting, and relates to the field of medical instruments. The device assisting C-arm machines with accurate shooting comprisestelescopic circular hoops, wherein a plurality of mounting seats are arranged on the circular hoops; the mounting seats are detachably and fixedly connected to the circular hoops; a battery frame is arranged in each mounting seat; a laser lamp placing groove is formed in one side of the battery frame; a laser lamp is arranged in each laser lamp placing groove; an emission hole is formed in each mounting seat; each emission hole is communicated with each laser lamp placing groove; each laser lamp is a cross laser lamp; and each emission hole is eccentrically arranged against each laser lamp. The device has the beneficial effects that: the device can effectively and continuously fix the laser lamps, avoids the change of the laser beam angle caused by the displacement of the laser lamps, conveniently replaces the lost laser lamps, has a simple structure, can be installed on C-arm machines of different types easily, has low manufacturing cost and high cost performance, and can be popularized and applied all over the country.

Description

technical field [0001] The invention mainly relates to the field of medical equipment, in particular to an auxiliary C-arm machine precision shooting device. Background technique [0002] C-arm X-ray machine (referred to as C-arm machine) is a mobile X-ray machine that integrates light, machine, and image processing technologies. It is one of the most commonly used surgical aids in orthopedic surgery. When shooting, place the image intensifier and tube of the C-arm machine on both sides of the target area, adjust the appropriate angle, and take a film to obtain the image. However, to obtain a satisfactory image, the image intensifier must be accurately centered in the target area, and the perspective angle needs to be adjusted. [0003] The perspective range of the C-arm machine currently used clinically is small, and basically does not have a pre-alignment device. Before fluoroscopy, visually evaluate whether the C-arm machine can effectively capture the image of the targ...
