Embodiment 1

[0029] The developer 8, the developer 8 is selected as colloid or emulsion, which is convenient to flow out after being squeezed, and is also convenient to apply on the surface of the human body or deep tissues. The developer 8 contains an X-ray-impermeable material, such as commonly used barium. The developer 8 can be a mixture of barium and X-ray-transparent ordinary gel. The barium is evenly distributed in the developer 8. After applying the developer 8 to the target position of the medical operation, take a fluoroscopy, such as CT, which can be seen on the CT film The development point and bone shape of the barium agent make it possible to correspond the CT film and the human body point by point more accurately and intuitively through the contrast agent 8 applied on the human body when comparing the CT film with the human body, so that when the operation is broken , The point determination is more accurate, and the correct position can be opened at one time, reducing surgi...

Abstract

The embodiment of the invention provides a marking pen for fluoroscopy, and belongs to the technical field of marking pens. The marking pen is used for developer application and comprises a pen holder which is internally provided with a first containing cavity, a push rod which is arranged in the first containing cavity and above a developer, a pushing part which is connected with the push rod and a stress part which is acted on the pushing part, wherein the developer is arranged in the first containing cavity, the pushing part is acted on the push rod, and makes the developer move out of the pen holder through the push rod, so that a medical image corresponds to a surgical part visually conveniently, and the technical effects of reducing medical maloperation, reducing surgical trauma and reducing surgical complications are achieved.

Description

technical field [0001] The invention relates to the technical field of marker pens, in particular to a marker pen for perspective. Background technique [0002] At present, preoperative filming is performed before puncture or surgery, and the position and shape of bones, muscles or blood vessels are determined through filming, so that accurate operations can be performed during puncture or surgery. [0003] However, the current method of operation requires the surgeon to empirically match the captured medical image with the surgical site, and the accuracy of the correspondence between the medical image and the surgical site is usually affected by multiple factors, for example: the surgeon’s operation Experience, the location of the surgical site, the accuracy of the medical imaging itself; changes in the patient's body position during X-ray filming, etc. [0004] Therefore, the technical problem of the existing technology is that the relationship between medical images and ...
