Description

Auxiliary device for CT wrist joint examination

Technical Field

The utility model relates to the technical field of medical supplies, in particular to an auxiliary device for CT wrist joint examination.

Background

The wrist joint is the vulnerable site of many diseases, and the lesions often appear to invade the articular surfaces as the primary change or manifestation. Although clinical diagnosis can be performed by means of X-ray plain film, CR and DR, the density resolution of the X-ray plain film, CR and DR is far inferior to that of CT, and the display of fine lesions is a difficult problem in current image examination, and many diseases need to be seen more clearly under CT scanning.

During CT wrist joint examination, if a patient with trauma brake on the shoulder joint or the upper arm cannot use a normal body position for examination, the standard examination body position needs to be lifted to the top of the head by the arm, so that the condition that the patient is not overlapped with other tissues can be ensured, and the generation of artifacts is prevented. When the patient appears and can not be lifted, only order the patient with wrist joint put in the position of belly, be convenient for carry out the CT inspection, but also can cause like this with the overlapping of belly, human breathing can drive the belly and move together, can produce the motion artifact under such condition, be unfavorable for diagnosing some tiny fractures.

In order to solve the problems, the utility model provides an auxiliary device which can be used for CT wrist joint examination.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide an auxiliary device for CT wrist joint examination, which solves the problem of image artifacts caused by respiratory motion under the condition that an arm is braked or cannot be lifted.

In order to achieve the purpose, the utility model provides the following technical scheme:

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The utility model provides the following technical scheme:

as shown in the figure, the first and second,

example 1:

the auxiliary device for the CT wrist joint examination comprises a supporting plate 1, wherein a U-shaped plate 4 and a supporting column 5 are respectively arranged on the upper surface and the lower surface of the supporting plate 1, the U-shaped plate 4 can be inwards concave on the supporting plate 1 or can be independently arranged outside the supporting plate 1, and the wrist joint is placed on the U-shaped plate 4; the number of the supporting columns 5 can be two, if the number of the supporting columns 5 is two, the two supporting columns 5 are respectively arranged on two sides of the supporting plate 1, and a connecting piece is arranged on each of the two supporting columns 5; the one end that layer board 1 was kept away from to support column 5 is provided with stand 8, and the one end that support column 5 was kept away from to stand 8 is provided with and is used for fixing at abdominal dead lever 6, if the quantity of support column 5 is when two, sets up stand 8 on the connecting piece.
