A Kirschner wire puncture positioner for fracture reduction treatment

Abstract

Provided is a puncture locator for kirschner pins used for treatment of facture reduction. The puncture locator comprises a guide pipe and a positioning rack. A guide channel, through which a first kirschner pin is allowed to penetrate, is formed by communication along an axial direction. The positioning rack is movably arranged on the guide pipe along the guide pipe. The front end of the positioning rack is provided with a clamping part opposite to the front end of the guide pipe. An avoidance groove, through which the first kirschner pin is allowed to penetrate, is formed at the clamping part. The positioning rack is operated to move along the guide pipe such that the clamping part and the front end of the guide pipe are matched to clamp a fracture position. The puncture locator for the kirschner pins used for treatment of facture reduction can be used for minimally-invasive closed reduction, fixation and capable of accurately guiding penetration.

Description

technical field [0001] The invention relates to a Kirschner wire puncture positioner for fracture reduction treatment. Background technique [0002] Many fractures need to be fixed with Kirschner wires and hollow screws after reduction. Clinically, reduction forceps, bone holders, etc. are commonly used to clamp the fracture end for reduction, and then reposition the angle and direction of the Kirschner wires to pass the needles. When it is necessary to fix with tension bands It is also possible to further strip the tissue around the fracture end, causing considerable damage to the blood supply of the fracture end, and the angle and direction of the puncture needle cannot be accurately positioned, and repeated punctures are often required, which also has a negative impact on the healing of the fracture. At present, minimally invasive technology is developing rapidly, and the minimally invasive treatment of fractures is the current mainstream direction. However, the lack of s...

Problems solved by technology

[0002] Many fractures need to be fixed with Kirschner wires and hollow screws after reduction. Clinically, reduction forceps, bone holders, etc. are commonly used to clamp the fracture end for reduction, and then reposition the angle and direction of the Kirschner wires to thread the needles. Tension bands are often used for fixation. It is also possible to further strip the tissue around the fracture end, causing considerable damage to the blood supply of the fracture end, and the angle and direction of the puncture needle cannot be accurately positioned, and repeated punctures are often required, which also has a negative impact on the healing of the fracture

At present, minimally invasive technology is developing rapidly, and minimally invasive treatment of fractures is the current mainstream direction, but the lack of suitable tools is a major problem
