Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention has advantages such as no need to use screws, no secondary damage to the body, convenient locking and fixing of the hands and feet of people of different shapes, wide application range of the hands and feet fixation device, and strong practicability. The traditional external fixation device for hand and foot fractures needs to drive screws into the bones, which will cause secondary damage to body tissues and bones. However, the hand and foot bones are thinner, and the method of screw drilling and fixing will cause greater damage to the hand and foot bones. Moreover, the existing fracture external fixation device can only fix a single hand or foot, and the device has relatively large limitations. The present invention provides the following technical solution: a miniature locking external fixation device for the treatment of hand and foot fractures, including Assemblies, the connection assembly includes a lower connection mechanism and an upper connection mechanism;

Abstract

The invention provides a miniature locking external fixing device for hand and foot bone fracture treatment, and the miniature locking external fixing device for hand and foot bone fracture treatment comprises a connecting assembly which comprises a lower connecting mechanism and an upper connecting mechanism. According to the miniature locking external fixing device for hand and foot bone fracture treatment, the distance between a hollow plate and a fixing box is located at a proper position, the hand of a patient is inserted into a fixing groove through the interior of the hollow plate, a first rotary knob is rotated, at the moment, five transverse clamping plates can fix fingers of the hand of the patient, and a second rotary knob is rotated; at the moment, the arc-shaped clamping plate can fix the wrist of the patient, and therefore the effects that screws are not needed, secondary damage to the body is avoided, and the hands and feet of people with different figures can be locked and fixed conveniently are achieved. The hollow plate is rotated upwards, at the moment, initial hand fixing is converted into foot fixing, and therefore the effects that the device capable of fixing the hands and the feet is wide in application range and high in practicability are achieved.

Description

technical field [0001] The invention relates to the technical field of fracture treatment, in particular to a miniature locking external fixation device for treatment of hand and foot bone fractures. Background technique [0002] A fracture is a complete or partial break in the continuity of the bone structure. It is more common in children and the elderly, and it also occurs from time to time in young and middle-aged people. Patients often have fractures in one part, and a few have multiple fractures. After timely and appropriate treatment, most patients can recover their original functions, and a few patients may have sequelae of varying degrees. [0003] External fixation devices are required for the treatment of hand and foot fractures. The existing external fixation devices for hand and foot fractures require screws to be driven into the bone, which will cause secondary damage to body tissues and bones. However, the hand and foot bones are thinner, and the screws are d...
