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

Embodiment Construction

[0022] The present invention will be further described below in conjunction with drawings and embodiments.

[0023] Now in conjunction with accompanying drawing 1-4, illustrate the mechanical structure of the present invention: Fig. 1 and Fig. 2 show that the present invention is to be made up of a booster 3 and two supporting devices 11,17 on a base plate 1, and booster 3 is made up of again Horizontal screw rod 6 and vertical rod 27 are formed, and one end of horizontal screw rod 6 is equipped with pressure head 23, and it is made of detachable pressure plate 9 and nut 22, and the other end is equipped with the nut 4 that adjusts the horizontal rod to move and add force and after adding force. A "dynamometer" that can display numbers. During operation, the force of turning the nut 4 is transmitted through the thread transmission on the horizontal rod to pressurize the relevant parts of the hand, and the quantitative force is displayed on the "digital display instrument for m...

Abstract

A mechanical force-applying table for the X-ray photography and diagnosis apparatus to diagnose if the lateral ligamenta collateralia of the joints of thumb and / or other fingers is broken by mechanically applying force is composed of a base plate, a force applying unit with 2-3 force-applying heads and a digital force display, and two supporters with multi-angle turned press head.

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...
