Abstract
Double-head thread needle relates to an internal fixation device for treatment of collarbone and ulnar fracture and is primarily designed to solve the problems that the bone gomphosis force of the prior round bone needle is small and the prior round bone needle easily slips. A80mm long thread is separately provided at the two ends of a needle of about 220 mm long. Advantages: the device with bone has strong gomphosis force and will not slip or loosen, and thus fracture easily heals.
Description
This utility model relates to a kind of clavicle, used internal fixation apparatus of ulnar fracture for the treatment of.
Treatment clavicle, ulnar fracture internal fixation apparatus commonly used are osseous pin, plate and screw etc. at present, and shortcoming is that osseous pin is smooth, and is little with the bone inlay resultant force, and easily slippage in case slippage can be thrust thoracic cavity, the lobe of the lung and aorta etc., causes severe complication; The loosening internal fixation that also can cause of osseous pin is failed, and fracture redisplacement etc. occurs.Adopt plate screw fixedly when clavicle, ulnar fracture, it is more extensive to peel off the periosteum scope, and fixing back easily produces stress shielding, is unfavorable for union of fracture, and holes and unintentionally drill bit is punctured pleura, blood vessel, nerve sometimes.After union of fracture, the second operation of still needing is got steel plate screw, increases patient suffering and medical expense.
The purpose of this utility model is used for internal fixation when being a kind of treatment clavicle of design, ulnar fracture, and is good with the bone inlay resultant force, not eely double thread pin.
Above-mentioned purpose can be realized by following proposal, establishes screw thread 2 respectively at two of pin 1.
Usage: along patient's clavicle upper limb is that center work one is about the 30-60mm otch with the fracture, peel off a little periosteum, appear fracture site, double thread pin with pulp cavity diameter coupling is pierced folding end far away with boring to drive in the wrong direction, and pin passes from the clavicle far-end, with fracture anatomical reduction, again the double thread pin is oppositely inwardly pierced, cross fracture 30-50mm, can fixedly secure, wipe out screw needle and expose the outer excessive portion of skin.
The utility model has the advantages that: because there is screw thread at two of pin, with bone stronger inlay resultant force is arranged, slippage, loosening phenomenon can not occur, fracture is healing easily.
Accompanying drawing is a structural representation of the present utility model.
Embodiment: make the pin that is about 220mm, respectively establish the screw thread 2 of long 80mm at two of pin, the diameter of pin 1 is divided into three kinds of 3.0mm, 3.5mm, 4.0mm.
Claims (2)
1, a kind of double thread pin comprises pin [1], it is characterized in that screw thread [2] is established at two of pin respectively.
2, according to the described double thread pin of claim 1, it is characterized in that pin [1] is about 220mm, respectively there is the long screw thread [2] of 80mm at pin two, and the diameter of pin is divided into three kinds of 3.0mm, 3.5mm, 4.0mm.
