Stent for assisting CT diagnosis of tarsometatarsal joint injury

Abstract

The invention discloses a stent for assisting computed tomography (CT) diagnosis of tarsometatarsal joint injury. The stent comprises a stent main body, a foot fixer, a pedal, an inner tube and an adjusting piece, wherein the inner tube is fixedly arranged on the stent main body; the adjusting piece is arranged on the inner tube in a rotatable and sliding mode; and both the foot fixer and the pedal are fixedly connected with the adjusting piece. The stent for assisting the CT diagnosis of the tarsometatarsal joint injury can assist a patient in maintaining a foot at a plantar flexion ectropion position in the CT diagnosis process, so that diagnosis is facilitated, the requirement of the CT diagnosis for the flexion direction of the foot of the patient is met, the CT diagnosis operation can be accurately performed, and the accuracy and the precision of the diagnosis result are ensured.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a support for assisting CT in diagnosing tartartarsal joint damage. Background technique [0002] Although metatarsal joint fracture is a rare foot injury, once a metatarsal joint fracture occurs, it can seriously affect the quality of life of the patient. Early diagnosis and early treatment have a greater impact on the patient's recovery. Because metatarsal joint fractures are often not obvious in X-ray examination, the missed diagnosis rate is as high as 20%. According to the differences in X-ray absorption and transmittance of different tissues of the human body, CT uses highly sensitive instruments to measure the human body, and then inputs the data obtained from the measurement into a computer, which processes the data and then Take a cross-sectional or three-dimensional image of the inspected part of the human body, and find small lesions in any part of the body. Therefore...

Problems solved by technology

However, the brackets (such as Brown's frame) commonly used in orthopedics in medicine cannot maintain the position of the patient's foot, which brings inconvenience to CT examination and easily leads to inaccurate diagnosis or low accuracy of diagnostic results.

In addition, most of the currently used orthopedic brackets are opaque and cannot be used for CT examinations
