Limb fracture reduction device

Abstract

The invention relates to a limb fracture repositor which comprises a stretching guide rod and a half-ring shaped needle bed track that is axially opened with a ring-shaped continuous manger along a ring-shaped circumferential end surface. The stretching guide rod is formed by connecting a plurality of sub guide rods by a coupling sleeve. An arc rack is embedded in the ring-shaped continuous manger. A needle bed positioning gear which is meshed with the arc rack is arranged in the ring-shaped continuous manger and is connected with an arc needle bed that is buckled on the half-ring shaped needle bed track. The arc needle bed is fixedly and radially connected with a cylindrical outer casing. A lifting pull rod is arranged in the cylindrical outer casing, the upper end of which is equipped with a lifting knob. The lower end of the lifting pull rod is equipped with a needle clipping device. The limb fracture repositor realizes the circumferential, axial and radial flexible adjustment of a fixed needle on a catagmatic limb, substitutes the treatment function of the manual reposition, has the advantages of precise reposition, being easy to master strength and convenient to adjust slimly and avoids the defects of the manual reposition.

Description

technical field [0001] The invention belongs to the field of medical devices, and relates to a limb fracture reducer, in particular to an adjustable limb fracture reducer. Background technique [0002] For a long time, our country has been following previous experience in the treatment of fractures, tending to use manipulation techniques to reset fractures, so as to achieve the purpose of treatment. Whether it is modern western medicine treatment or traditional Chinese medicine bonesetting, it can be summed up to form a three-dimensional impression of the fracture site by carefully touching the injured part on the basis of imaging data, and then use manual techniques to perform closed reduction of general fractures based on empirical judgment. Manipulative skills generally include pulling and stretching, rotating and stretching, lifting and squeezing, squeezing and splitting bones, folding and turning, and so on. The use of these techniques for reduction often has disadvant...

Problems solved by technology

The use of these techniques for reduction often has disadvantages such as inaccurate reduction, difficulty in grasping the strength, and difficulty in making fine adjustments, so that the fracture segment cannot achieve anatomical reduction, and what is more, even the basic functional reduction cannot be satisfied, resulting in treatment failure. Bring huge economic losses and mental trauma to patients

[0003] At present, in the treatment of fracture reduction, external fixators are also used as treatment methods, but this kind of external fixator has the disadvantages of small reduction movement range and insufficient flexibility.
