Auxiliary device used for horizontal-position load-bearing part X-ray photography

Abstract

The invention discloses an auxiliary device used for horizontal-position load-bearing part X-ray photography. The device includes a supporting board, a vertical guide rod, a spiral screw rod, a movable cross arm and a fixed cross arm; the vertical guide rod is fixed on the supporting board through a casing clamp; one end of the fixed cross arm and one end of the movable cross arm are fixed on thevertical guide rod; the other end of the movable cross arm is connected with the spiral screw rod through a screw drive structure; the other end of the fixed cross arm is connected with a lower gasket; one end of the spiral screw rod is connected with a rotating handle, and the other end of the spiral screw rod is connected with an upper gasket. The casing clamp and the supporting board are fixedthrough fixing screws; the fixed cross arm and the lower gasket are fixed through a buckle, the spiral screw rod and the rotating handle are fixed through cup joint, and the spiral screw rod and the upper gasket are fixed through a buckle; the middle of the vertical guide rod is an arc-shaped groove, and the two sides of the vertical guide rod are latch structures. The device is suitable for X-rayphotography of knee joints, ankle joints, feet or other load-bearing parts of patients.

Description

technical field [0001] The invention relates to a medical appliance, in particular to an auxiliary device which can be used for X-ray photography in the supine position and weight-bearing position. Background technique [0002] Standing position imaging examination has been the focus of both clinical and imaging circles since the birth of imaging diagnosis. Standing weight-bearing X-ray examination of the knee joint, ankle joint or foot, which is widely used in clinical practice, has become a part of clinical disease diagnosis and judicial disability identification because it can objectively reflect the biomechanical changes in the natural standing state of the human body. An indispensable imaging tool. Since the feet or ankle joints are located at the bottom of the human body during standing weight-bearing X-ray photography, the minimum height that the current X-ray camera can descend is limited, so it is often necessary for the subject to stand on a support with a certain...

Problems solved by technology

A scientific researcher has invented an X-ray photographic frame specially used for the horizontal lateral position of children's foot load. The name of the invention is a horizontal lateral X-ray frame of child's foot load. The Chinese patent publication number is CN204394549U, and the publication date is June 2015. On the 17th, the device solved the problem that the minimum height of the machine is limited during the X-ray examination of the foot-bearing position. It can shoot relatively standard X-ray films of the foot-bearing position of children. Designed according to the structural size of children's feet, it cannot be used for weight-bearing X-ray photography of adult knee joints, ankle joints, etc. Its application value cannot take weight-bearing X-ray photos that meet clinical needs, causing certain troubles to clinical diagnosis and judicial disability identification. Therefore, there is an urgent need for an auxiliary device that can be used for supine weight-bearing X-ray photography
