X rays photographic diagnostic bench for finger joints collateral ligamentum crack due to mechanical stressing

Abstract

The present invention is composed of a base plate with a booster and two support devices, the booster has a booster pressure head and a "force-measuring digital display instrument"; the two support devices are multi-angle rotating pressure heads. Use 3 or 2 indenters to quantitatively apply mechanical force to stretch the different joint spaces of the thumb / finger of the injured hand and the corresponding joint spaces of the healthy hand, take X-rays of both hands, compare the size of the two spaces, and diagnose lateral ligament rupture and no. The present invention can completely avoid X-ray damage to the operator, and because quantitative mechanical force is used to avoid errors caused by subjective factors of manual force force, the diagnosis is more accurate.

Description

technical field [0001] The invention relates to an instrument in the field of medical diagnosis, which is used for quantifying mechanical force on the side of the thumb metacarpophalangeal joint and the thumb / interphalangeal joint to open the joint space of the injured side (radial or ulnar side) and compare the X-ray films of the injured side The difference between the size of the gap between the X-rays of the corresponding joints of the healthy hand and the healthy hand is used to diagnose or exclude the rupture of the lateral ligaments of each joint of the thumb / finger. Background technique [0002] The rupture of the collateral ligament of the metacarpophalangeal joint of the thumb, especially the ulnar collateral ligament, and the rupture of the collateral ligament of the thumb / interphalangeal joint is a common type of non-fracture closed injury of the hand. [0003] So far, the X-ray diagnostic method is to stretch the side joint space of the injured side with bare han...

Problems solved by technology

[0004] In order to avoid radiation damage from X-ray exposure, medical personnel can use lead-containing protective aprons and lead-containing gloves when they are in the range of radiation exposure. The interference of the gloves is very inconvenient, so I have to give up using them. In this way, the hands are directly exposed to radiation exposure. Due to repeated occupational operations, radiation damage is inevitable. In addition, the uneven force applied by bare hands and no quantitative standards also affect the diagnosis. the accuracy of
