Detachable stress position radiography joint compression device

Abstract

A detachable stress position radiography joint pressurization device is characterized in that it includes a stress support, a plurality of sliding positioning blocks and a joint pneumatic pressurization device, the stress support is provided with a number of positioning holes, and the sliding positioning blocks are sleeved On the stress bracket, the spring bayonet assembly is provided on the sliding positioning block, and the bayonet pin of the spring bayonet assembly is clamped in the positioning hole, and the joint pneumatic pressure device is arranged on the sliding positioning block located in the middle of the stress bracket; The sliding positioning block at the upper part of the bracket is provided with a large-size supporting positioning collar; the sliding positioning block at the lower part of the stress support is provided with an ankle fixing seat. By adding components with different functions, it is possible to realize stress-level radiography of various joints. The joint compression device is suitable for different joints; the modular design and generalized components are not only convenient for production, but also easy and reliable for maintenance and use; it can be effective Reduce medical staff's exposure to radiation and protect their health.

Description

technical field [0001] The invention relates to a medical auxiliary device, in particular to a detachable joint pressurization device used for joints such as ankle joints, knee joints and elbow joints. Background technique [0002] At present, trauma to the knee, ankle, and elbow is a common clinical trauma in orthopedics, often leading to ligament damage or fracture. Due to the combined effects of direct violence, post-injury falls, and body twisting, the bone and ligament injuries of the ankle are often very complicated. It is difficult to understand all the injuries through physical examinations and conventional X-rays, and even CT scans and MRIs Not entirely sure either. [0003] In particular, the knee joint is the most complex and largest joint in the whole body, and injuries to the cruciate ligament and collateral ligament of the knee can not only cause instability of the knee, but even cause disability, so early diagnosis and treatment are particularly important.

Problems solved by technology

[0004] Stress position radiography requires doctors or technicians to assist patients in positioning, and requires doctors or technicians to continuously apply stress to the patient's examination parts during the entire radiography process, but the strength exerted by each person, or even the strength exerted by the same person every time, cannot Precisely quantified, thus introducing a large bias to diagnosis

[0005] In addition, physicians and technicians must be exposed to X-rays during the filming process, and receive more radiation exposure, which will have different degrees of impact on their bodies
