Abstract
The utility model belongs to a medical appliance, mainly relating to an inner fixing needle for fracture. The utility model is a cylindrical rod made of stainless steel, one end of the utility model is in the shape of a triangular edge, and the other end of the utility model is in the shape of a triangular cone. In the process of the operations of the inner fixation of fracture, the utility model can be inserted clockwise or counterclockwise conveniently, which can shorten the time of operations and relieve the pain of patients.
Description
This utility model belongs to medical apparatus and instruments, relates generally to bone fracture internal fixing device.
Existing long bone shaft fracture Internal fixation pin commonly used is fixed.When run into old fracture, medullary cavity has callus formation, or medullary cavity is when having thinner phalange folding, now adopts the Kirschner wire direct motion to squeeze into fracture disconnected section far away usually, and then drives in the wrong direction and squeeze into fracture site.Because the Kirschner wire afterbody is more neat cylinder section, be difficult for driving in the wrong direction and squeeze into fracture site, bring difficulty to operation technique, bring big painful to patient.
The purpose of this utility model provide a kind of in the fracture internal fixation operation retrogradation needle Internal fixation pin of fracturing easily.
This utility model is by the cylinder stainless steel bar of an end band triangle tooth shape, makes triangular pyramidal at the other end of cylinder stainless steel bar, the retrogradation needle in the internal fixation operation that helps fracturing.
The utility model is described in further detail below in conjunction with accompanying drawing:
Among the figure: an end of cylinder stainless steel bar 2 is triangle tooth shapes 1, and the other end is a triangular pyramidal 3, and the cylinder stainless steel bar adopts φ 4～8mm, and length is about 20cm.
Triangle tooth shape angle of the present utility model is 15 °～20 °, in the internal fixation operation of fracturing, can direct motion of more convenient ground or retrogradation needle, and to shorten operating time, alleviate patient's misery.
