A clavicle intramedullary nail fixation anchor and a clavicle intramedullary nail fixation device

Abstract

The invention belongs to the technical field of clavicular fracture fixation, and in particular relates to a clavicle intramedullary nail fixation anchor and a clavicular intramedullary nail fixation device. The present invention includes a basic screw sleeve, the outer wall of which is used to fit on the positioning hole at the clavicle in an expansion or threaded manner, and the lumen of the basic screw sleeve is formed so that the intramedullary nail can enter through the positioning hole The passing cavity of the clavicle medullary cavity; the fixation anchor of the clavicle intramedullary nail also includes a positioning piece for radially locking the end of the intramedullary nail. The clavicle intramedullary nail anchor achieves reliable positioning of the end of the intramedullary nail, and prevents the intramedullary nail from falling off and accidentally twisting in the intramedullary cavity of the clavicle; while the clavicle intramedullary nail fixation device is used for minimally invasive Under the environment, it can realize the efficient fixation function of the fractured clavicle.

Description

technical field [0001] The invention belongs to the technical field of clavicular fracture fixation, and in particular relates to a clavicle intramedullary nail fixation anchor and a clavicular intramedullary nail fixation device. Background technique [0002] The clavicle is an S-shaped frame between the manubrium sternum and the acromion, and is the bony support that connects the upper limbs to the trunk. The clavicle is located under the skin and is superficial. It is prone to fracture when it is subjected to external force. The incidence rate accounts for 5% to 10% of all fractures in the whole body, and it mostly occurs in children and young adults. Middle clavicle fracture is a common clinical fracture. The traditional treatment method requires incision to expose the fracture area, and then uses reduction plate for reduction and fixation. This method has long incision, large trauma, great damage to the soft tissue around the fracture, and much bleeding during operation...

AI Technical Summary

Problems solved by technology

Obviously, on the one hand, the two ends of the main nail need to be installed with bulkheads, which are prone to fall off during use or when the intramedullary nail is removed, causing safety accidents

On the other hand, the main nail is installed along the medullary cavity of the clavicle, which is inconvenient for the operation, especially the removal after the operation is even more problematic. The patient suffers more pain, and at the same time, the ability to resist torsion and rotation is also poor, which brings disadvantages to later healing and rehabilitation. Hidden danger

Finally, the fixation of the entire main nail depends entirely on the self-tapping properties of the locking nail relative to the clavicle body, and the reliability of the main nail is also in doubt.
